"The worst is still yet to come": Grim warning for chocolate lovers

Chocolate lovers could be facing a potential nightmare ahead of the festive season as cocoa supplies hit an all time low, driving confectionary prices to a record high. Most of the world's cocoa beans are grown in West Africa, where ongoing inclement weather and crippling crop diseases, coupled with economy-wide pressures like rising labour, packaging and energy costs, have put unprecedented pressure on the chocolate industry in recent months. However, market analyst Rabobank’s Paul Joules told <a title="www.smh.com.au" href="https://www.smh.com.au/politics/federal/why-a-global-cocoa-crunch-will-sour-chocolate-for-years-to-come-20240927-p5ke0w.html" target="_blank" rel="noopener">The Sydney Morning Herald, </a> “the worst is still yet to come for consumers”, as the stockpiles of cocoa that manufacturers have been relying on for the past 18 months have run out. “While hedging has protected many manufacturers from the worst effects of the price rises until now, eventually all these forward contracts will get used up, and prices will have to increase to reflect the current cocoa price,” Rabobank’s Soaring chocolate prices report, released last week, read. Rabobank wanted that the increased costs of manufacturing will be passed down to consumers, with dark chocolate lovers being the most affected due to the high concentration of cocoa. Analysis by Mr Joules found that, worldwide, a 100 gram block of chocolate with 70 per cent cocoa content could rise from $4.90 to $6.50, with a “similar increase could be expected in Australia”. “It can take anywhere from six to 12 months for … price hikes to be reflected in the retail pricing of products,” Saxo Head of Commodity Strategy, Ole Sloth Hansen said. “The trend of shrinkflation is likely to become more pronounced. Consequently, while there might not be a stark rise in the price tags of chocolate items, the quantity offered for the same price will see a reduction.” Image credits: Shutterstock

Thinking of trying a new diet? 4 questions to ask yourself before you do

<a href="https://theconversation.com/profiles/melissa-eaton-1522868">Melissa Eaton</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a>; <a href="https://theconversation.com/profiles/verena-vaiciurgis-1647095">Verena Vaiciurgis</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a>, and <a href="https://theconversation.com/profiles/yasmine-probst-235268">Yasmine Probst</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> We live in a society that glorifies dieting, with around <a href="https://doi.org/10.1111%2Fobr.12466">42% of adults globally</a> having tried to lose weight. Messages about <a href="https://doi.org/10.2196/38245">dieting and weight loss</a> are amplified on social media, with a never-ending cycle of weight loss fads and diet trends. Amid often conflicting messages and misinformation, if you’re looking for diet advice online, it’s easy to become confused and overwhelmed. So before diving into the latest weight loss trend or extreme diet, consider these four questions to help you make a more informed decision. <h2>1. Is the diet realistic?</h2> Have you considered the financial cost of maintaining the diet or lifestyle, and the time and resources that would be required? For example, do you need to purchase specific products, supplements, or follow a rigid meal plan? If the diet is coming from someone who is trying to sell you something – such as a particular weight-loss product you need in order to follow the diet – this could be a particular red flag. Many extreme diet recommendations come from a place of privilege and overlook food access, affordability, cooking skills, where you live, or even your culture and ethics. If the diet has these sorts of issues it can lead to <a href="https://doi.org/10.1017/S1368980024000132">frustration, stress, stigmatisation</a> and feelings of failure for the person trying to adhere to the diet. But the problem may be with the diet itself – not with you. <h2>2. Is there evidence to support this diet?</h2> Self-proclaimed “experts” online will often make claims focused on specific groups, known as <a href="https://doi.org/10.4103%2F0972-6748.77642">target populations</a>. This might be 30- to 50-year-old men with diabetes, for example. In some cases, evidence for claims made may come from animal studies, which might not be applicable to humans at all. So be aware that if research findings are for a group that doesn’t match your profile, then the results might not be relevant to you. It takes time and a lot of high-quality studies to tell us a “diet” is safe and effective, not just one study. Ask yourself, is it supported by multiple studies in humans? Be critical and question the claims before you accept them. For accurate information look for government websites, or ask your GP or dietitian. <h2>3. How will this diet affect my life?</h2> Food is much more than calories and nutrients. It plays many roles in our lives, and likewise diets can influence our lives in ways we often overlook. Socially and culturally, food can be a point of <a href="https://doi.org/10.1017/S1368980024000132">connection and celebration</a>. It can be a source of enjoyment, a <a href="https://doi.org/10.1016/j.jbusres.2018.12.024">source of</a> comfort, or even a way to explore new parts of the world. So when you’re considering a new diet, think about how it might affect meaningful moments for you. For example, if you’re going travelling, will your diet influence the food choices you make? Will you feel that you can’t sample the local cuisine? Or would you be deterred from going out for dinner with friends because of their choice of restaurant? <h2>4. Will this diet make me feel guilty or affect my mental health?</h2> What is your favourite meal? Does this diet “allow” you to eat it? Imagine visiting your mum who has prepared your favourite childhood meal. How will the diet affect your feelings about these special foods? Will it cause you to feel stressed or guilty about enjoying a birthday cake or a meal cooked by a loved one? Studies have shown that dieting can negatively impact our <a href="https://doi.org/10.1007%2FBF03405201">mental health</a>, and skipping meals can increase symptoms of <a href="https://doi.org/10.1016/j.jagp.2020.01.160">depression and anxiety</a>. Many diets fail to consider the psychological aspects of eating, even though our mental health is just as important as physical health. Eating should not make you feel stressed, anxious, or guilty. So before starting another diet, consider how it might affect your mental health. <h2>Moving away from a dieting mindset</h2> We’re frequently told that weight loss is the path to better health. Whereas, we can prioritise our health without focusing on our weight. Constant messages about the need to lose weight can also be harmful to mental health, and not necessarily helpful for <a href="https://doi.org/10.1152/ajpregu.00755.2010">physical health</a>. Our research has found eating in a way that prioritises health over weight loss is linked to a range of <a href="https://doi.org/10.1016/j.appet.2024.107361">positive outcomes</a> for our health and wellbeing. These include a more <a href="https://books.google.com.au/books?hl=en&lr=&id=IuZzDgAAQBAJ&oi=fnd&pg=PT9&dq=%22relationship+with+food%22&ots=e-NxLzUIFF&sig=s7p6_SijfgZE6Odx7ztV4xXPGp8&redir_esc=y#v=onepage&q=%22relationship%20with%20food%22&f=false">positive relationship</a> with food, and less guilt and stress. Our research also indicates <a href="https://doi.org/10.1016/j.appet.2024.107361">mindful and intuitive eating</a> practices – which focus on internal cues, body trust, and being present and mindful when eating – are related to lower levels of depression and stress, and greater body image and self-compassion. But like anything, it takes practice and time to build a positive relationship with food. Be kind to yourself, seek out <a href="https://www.sizeinclusivehealth.org.au/find-a-provider">weight-inclusive</a> health-care professionals, and the changes will come. Finally, remember you’re allowed to find joy in food.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237766/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/melissa-eaton-1522868">Melissa Eaton</a>, Accredited Practising Dietitian; PhD Candidate, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a>; <a href="https://theconversation.com/profiles/verena-vaiciurgis-1647095">Verena Vaiciurgis</a>, Accredited Practising Dietitian; PhD Candidate, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a>, and <a href="https://theconversation.com/profiles/yasmine-probst-235268">Yasmine Probst</a>, Associate Professor, School of Medical, Indigenous and Health Sciences, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Is white rice bad for me? Can I make it lower GI or healthier?

<a href="https://theconversation.com/profiles/emma-beckett-22673">Emma Beckett</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Rice is a <a href="http://www.ipni.net/publication/bci.nsf/0/42A2EA40E95CBD1385257BBA006531E9/$FILE/Better%20Crops%20International%202002-3%20p03.pdf">culinary staple</a> in Australia and around the world. It might seem like a given that brown rice is healthier than white and official <a href="https://www.eatforhealth.gov.au/eating-well/healthy-recipes/recipe-modification-tips">public health resources</a> often recommend brown rice instead of white as a “healthy swap”. But <a href="https://pubmed.ncbi.nlm.nih.gov/34441728/">Australians definitely prefer white rice</a> over brown. So, what’s the difference, and what do we need to know when choosing rice? <h2>What makes rice white or brown?</h2> Rice “grains” are technically seeds. A complete, whole rice seed is called a “paddy”, which has <a href="https://www.fao.org/4/t0567e/t0567e07.htm">multiple parts</a>: <ol> <li>the “hull” is the hard outer layer which protects the seed</li> <li>the “bran”, which is a softer protective layer containing the seed coat</li> <li>the “germ” or the embryo, which is the part of the seed that would develop into a new plant if was germinated</li> <li>the “endosperm”, which makes up most of the seed and is essentially the store of nutrients that feeds the developing plant as a seed grows into a plant.</li> </ol> Rice needs to be <a href="https://www.tandfonline.com/doi/pdf/10.1080/87559128509540778">processed</a> for humans to eat it. Along with cleaning and drying, the hard hulls are removed since we can’t digest them. This is how <a href="https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1541-4337.12449">brown rice is made</a>, with the other three parts of the rice remaining intact. This means brown rice is regarded as a “wholegrain”. White rice, however, is a “refined” grain, as it is <a href="https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1541-4337.12449">further polished</a> to remove the bran and germ, leaving just the endosperm. This is a mechanical and not a chemical process. <h2>What’s the difference, nutritionally?</h2> Keeping the bran and the germ means <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/cche.10322">brown rice has more</a> magnesium, phosphorus, potassium B vitamins (niacin, folate, riboflavin and pyridoxine), iron, zinc and fibre. The germ and the bran also contain more bioactives (compounds in foods that aren’t essential nutrients but have health benefits), like <a href="https://www.mdpi.com/1420-3049/28/2/532#:%7E:text=Brown%20rice%20(BR)%20is%20obtained,and%20phenolic%20compounds%20%5B3%5D.">oryzanols and phenolic compounds</a> which have antioxidant effects. But that doesn’t mean white rice is just empty calories. It <a href="https://www.glnc.org.au/wp-content/uploads/2011/04/GLNC_Rice-factsheet_WEB.pdf">still contains</a> vitamins, minerals and some fibre, and is low in fat and salt, and is naturally gluten-free. White and brown rice actually have <a href="https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1541-4337.12449">similar</a> amounts of calories (or kilojoules) and total carbohydrates. There are studies that show eating more white rice is linked to <a href="https://diabetesjournals.org/care/article/43/11/2625/35820/A-Global-Perspective-on-White-Rice-Consumption-and">a higher risk</a> of type 2 diabetes. But it is difficult to know if this is down to the rice itself, or other related factors such as socioeconomic variables or other dietary patterns. <h2>What about the glycaemic index?</h2> The higher fibre means brown rice has a <a href="https://www.sciencedirect.com/science/article/pii/S0002916523314862">lower glycaemic index</a> (GI), meaning it raises blood sugar levels more slowly. But this is highly variable between different rices within the white and brown categories. The <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/carbohydrates-and-the-glycaemic-index#:%7E:text=The%20glycaemic%20index%20(GI)%20is,simple'%20or%20'complex'.">GI system</a> uses low (less than 55), medium (55–70) and high (above 70) categories. <a href="https://glycemicindex.com/gi-search/?food_name=rice&product_category=&country=&gi=&gi_filter=&serving_size_(g)=&serving_size_(g)_filter=&carbs_per_serve_(g)=&carbs_per_serve_(g)_filter=&gl=&gl_filter=">Brown rices</a> fall into the low and medium categories. <a href="https://glycemicindex.com/gi-search/?food_name=rice&product_category=&country=&gi=&gi_filter=&serving_size_(g)=&serving_size_(g)_filter=&carbs_per_serve_(g)=&carbs_per_serve_(g)_filter=&gl=&gl_filter=">White rices</a> fall in the medium and high. There are specific <a href="https://www.gisymbol.com/low-gi-products/sunrice-doongara-low-gi-white-clever-rice-1kg/">low-GI types available</a> for both white and brown types. You can also lower the GI of rice by <a href="https://pubs.acs.org/doi/abs/10.1021/jf503203r">heating and then cooling it</a>. This process converts some of the “available carbohydrates” into “resistant starch”, which then functions like dietary fibre. <h2>Are there any benefits to white rice?</h2> The <a href="https://www.realsimple.com/brown-rice-vs-white-rice-8417468#:%7E:text=The%20eating%20experience%20between%20these,chewier%20texture%20and%20nuttier%20flavor.">taste and textural qualities</a> of white and brown rices differ. White rice tends to have a softer texture and more mild or neutral flavour. Brown rice has a chewier texture and nuttier flavour. So, while you can technically substitute brown rice into most recipes, the experience will be different. Or other ingredients may need to be added or changed to create the desired texture. Removing more of the outer layers may also reduce the levels of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10375490/">contaminants</a> such as pesticides. <h2>We don’t just eat rice</h2> Comparing white and brown rice seems like an easy way to boost nutritional value. But just because one food (brown rice) is more nutrient-dense doesn’t make the other food (white rice) “bad”. Ultimately, it’s not often that we eat just rice, so we don’t need the rice we choose to be the perfect one. Rice is typically the staple base of a more complex dish. So, it’s probably more important to think about what we eat with rice. Adding vegetables and lean proteins to rice-based dishes can easily add the micronutrients, bioactives and fibre that white rice is comparatively lacking, and this can likely do more to contribute to diet quality than eating brown rice instead.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236767/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/emma-beckett-22673">Emma Beckett</a>, Adjunct Senior Lecturer, Nutrition, Dietetics & Food Innovation - School of Health Sciences, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Food and exercise can treat depression as well as a psychologist, our study found. And it’s cheaper

<a href="https://theconversation.com/profiles/adrienne-oneil-268324">Adrienne O'Neil</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/sophie-mahoney-1557294">Sophie Mahoney</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Around <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&inline=true">3.2 million</a> Australians live with depression. At the same time, <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&inline=true">few</a> Australians meet recommended dietary or physical activity guidelines. What has one got to do with the other? Our world-first trial, <a href="https://www.thelancet.com/journals/lanwpc/article/PIIS2666-6065%2824%2900136-6/fulltext">published this week</a>, shows improving diet and doing more physical activity can be as effective as therapy with a psychologist for treating low-grade depression. Previous studies (including <a href="https://link.springer.com/article/10.1186/s12916-017-0791-y">our own</a>) have found “lifestyle” therapies are effective for depression. But they have never been directly compared with psychological therapies – until now. Amid a nation-wide <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">shortage</a> of mental health professionals, our research points to a potential solution. As we found lifestyle counselling was as effective as psychological therapy, our findings suggest dietitians and exercise physiologists may one day play a role in managing depression. <h2>What did our study measure?</h2> During the prolonged COVID lockdowns, Victorians’ distress levels were <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.50831">high and widespread</a>. Face-to-face mental health services were limited. Our trial targeted people living in Victoria with elevated distress, meaning at least mild depression but not necessarily a diagnosed mental disorder. Typical symptoms included feeling down, hopeless, irritable or tearful. We partnered with our <a href="https://www.barwonhealth.org.au/mhdas/">local mental health service</a> to recruit 182 adults and provided group-based sessions on Zoom. All participants took part in up to six sessions over eight weeks, facilitated by health professionals. Half were randomly assigned to participate in a program co-facilitated by an accredited practising dietitian and an exercise physiologist. That group – called the lifestyle program – developed nutrition and movement goals: <ul> <li>eating a wide variety of foods</li> <li>choosing high-fibre plant foods</li> <li>including high quality fats</li> <li>limiting discretionary foods, such as those high in saturated fats and added sugars</li> <li>doing enjoyable physical activity.</li> </ul> The second group took part in psychotherapy sessions convened by two psychologists. The psychotherapy program used cognitive behavioural therapy (CBT), the gold standard for treating depression in <a href="https://jamanetwork.com/journals/jamapsychiatry/article-abstract/2730724">groups and when delivered remotely</a>. In both groups, participants could continue existing treatments (such as taking antidepressant medication). We gave both groups <a href="https://link.springer.com/article/10.1186/s12888-022-03840-3">workbooks and hampers</a>. The lifestyle group received a food hamper, while the psychotherapy group received items such as a colouring book, stress ball and head massager. <h2>Lifestyle therapies just as effective</h2> We found similar results in each program. At the trial’s beginning we gave each participant a score based on their self-reported mental health. We measured them again at the end of the program. Over eight weeks, those scores showed symptoms of depression reduced for participants in the lifestyle program (42%) and the psychotherapy program (37%). That difference was not statistically or clinically meaningful so we could conclude both treatments were as good as each other. There were some differences between groups. People in the lifestyle program improved their diet, while those in the psychotherapy program felt they had increased their social support – meaning how connected they felt to other people – compared to at the start of the treatment. Participants in both programs increased their physical activity. While this was expected for those in the lifestyle program, it was less expected for those in the psychotherapy program. It may be because they knew they were enrolled in a research study about lifestyle and subconsciously changed their activity patterns, or it could be a positive by-product of doing psychotherapy. There was also not much difference in cost. The lifestyle program was slightly cheaper to deliver: A$482 per participant, versus $503 for psychotherapy. That’s because hourly rates differ between dietitians and exercise physiologists, and psychologists. <h2>What does this mean for mental health workforce shortages?</h2> Demand for mental health services is increasing in Australia, while at the same time the workforce <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">faces worsening nation-wide shortages</a>. Psychologists, who provide <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&inline=true">about half</a> of all mental health services, can have long wait times. Our results suggest that, with the appropriate training and guidelines, allied health professionals who specialise in diet and exercise could help address this gap. Lifestyle therapies can be combined with psychology sessions for multi-disciplinary care. But diet and exercise therapies could prove particularly effective for those on waitlists to see a psychologists, who may be receiving no other professional support while they wait. Many dietitians and exercise physiologists already have advanced skills and expertise in motivating behaviour change. Most accredited practising dietitians are trained in managing <a href="https://link.springer.com/content/pdf/10.1007/978-3-030-67929-3_38-1.pdf">eating disorders</a> or <a href="https://www.nature.com/articles/s41572-020-0200-2">gastrointestinal conditions</a>, which commonly overlap with depression. There is also a cost argument. It is <a href="https://journals.sagepub.com/doi/full/10.1177/1355819616668202">overall cheaper</a> to train a dietitian ($153,039) than a psychologist ($189,063) – and it takes less time. <h2>Potential barriers</h2> Australians with chronic conditions (such as diabetes) can access subsidised dietitian and exercise physiologist appointments under various Medicare treatment plans. Those with eating disorders can also access subsidised dietitian appointments. But mental health care plans for people with depression do not support subsidised sessions with dietitians or exercise physiologists, despite <a href="https://dietitiansaustralia.org.au/sites/default/files/2024-04/Dietitians%20Australia%20Mental%20Health%20Evidence%20Brief%202024.pdf">peak bodies</a> urging them to do so. Increased training, upskilling and Medicare subsidies would be needed to support dietitians and exercise physiologists to be involved in treating mental health issues. <a href="https://foodandmoodcentre.com.au/academy">Our training</a> and clinical <a href="https://www.tandfonline.com/doi/full/10.1080/15622975.2022.2112074">guidelines</a> are intended to help clinicians practising lifestyle-based mental health care within their scope of practice (activities a health care provider can undertake). <h2>Future directions</h2> Our trial took place during COVID lockdowns and examined people with at least mild symptoms of depression who did not necessarily have a mental disorder. We are seeking to replicate these findings and are now running <a href="https://foodandmoodcentre.com.au/projects/the-harmone-trial/">a study</a> open to Australians with mental health conditions such as major depression or bipolar disorder.

Cheeky diet soft drink getting you through the work day? Here’s what that may mean for your health

So what does the research say about how your health is affected in the long term if you drink them often? <h2>What makes diet soft drinks sweet?</h2> The World Health Organization (WHO) <a href="https://www.who.int/news/item/04-03-2015-who-calls-on-countries-to-reduce-sugars-intake-among-adults-and-children">advises</a> people “reduce their daily intake of free sugars to less than 10% of their total energy intake. A further reduction to below 5% or roughly 25 grams (six teaspoons) per day would provide additional health benefits.” But most regular soft drinks contain <a href="https://www.actiononsugar.org/surveys/2014/sugar-sweetened-beverages/">a lot of sugar</a>. A regular 335 millilitre can of original Coca-Cola contains at least <a href="https://www.coca-cola.com/ng/en/about-us/faq/how-much-sugar-is-in-cocacola-original-taste">seven</a> teaspoons of added sugar. Diet soft drinks are designed to taste similar to regular soft drinks but without the sugar. Instead of sugar, diet soft drinks contain artificial or natural sweeteners. The artificial sweeteners include aspartame, saccharin and sucralose. The natural sweeteners include stevia and monk fruit extract, which come from plant sources. Many artificial sweeteners are much sweeter than sugar so less is needed to provide the same burst of sweetness. Diet soft drinks are marketed as healthier alternatives to regular soft drinks, particularly for people who want to reduce their sugar intake or manage their weight. But while surveys of Australian <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7551593/">adults</a> and <a href="https://www.cambridge.org/core/journals/public-health-nutrition/article/adolescents-knowledge-and-beliefs-regarding-health-risks-of-soda-and-diet-soda-consumption/32F3E0FD6727F18F04C63F0390595131">adolescents</a> show most people understand the benefits of reducing their sugar intake, they often aren’t as aware about how diet drinks may affect health more broadly. <h2>What does the research say about aspartame?</h2> The artificial sweeteners in soft drinks are considered safe for consumption by food authorities, including in the <a href="https://www.fda.gov/food/food-additives-petitions/aspartame-and-other-sweeteners-food">US</a> and <a href="https://www.foodstandards.gov.au/consumer/additives/aspartame">Australia</a>. However, some <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4899993/">researchers</a> have raised concern about the long-term risks of consumption. People who drink diet soft drinks regularly and often are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446768/">more likely</a> to develop certain metabolic conditions (such as diabetes and heart disease) than those who don’t drink diet soft drinks. The link was found even after accounting for other dietary and lifestyle factors (such as physical activity). In 2023, the WHO announced reports had found aspartame – the main sweetener used in diet soft drinks – was “<a href="https://www.who.int/news/item/14-07-2023-aspartame-hazard-and-risk-assessment-results-released">possibly carcinogenic to humans</a>” (carcinogenic means cancer-causing). Importantly though, the report noted there is not enough current scientific evidence to be truly confident aspartame may increase the risk of cancer and emphasised it’s safe to consume occasionally. <h2>Will diet soft drinks help manage weight?</h2> Despite the word “diet” in the name, diet soft drinks are not strongly linked with weight management. In 2022, the WHO conducted a <a href="https://www.who.int/news/item/15-05-2023-who-advises-not-to-use-non-sugar-sweeteners-for-weight-control-in-newly-released-guideline">systematic review</a> (where researchers look at all available evidence on a topic) on whether the use of artificial sweeteners is beneficial for weight management. Overall, the randomised controlled trials they looked at suggested slightly more weight loss in people who used artificial sweeteners. But the observational studies (where no intervention occurs and participants are monitored over time) found people who consume high amounts of artificial sweeteners tended to have an increased risk of higher body mass index and a 76% increased likelihood of having obesity. In other words, artificial sweeteners may not directly help manage weight over the long term. This resulted in the WHO <a href="https://www.who.int/news/item/15-05-2023-who-advises-not-to-use-non-sugar-sweeteners-for-weight-control-in-newly-released-guideline">advising</a> artificial sweeteners should not be used to manage weight. <a href="http://www.cell.com/cell-metabolism/fulltext/S1550-4131(16)30296-0">Studies</a> in animals have suggested consuming high levels of artificial sweeteners can signal to the brain it is being starved of fuel, which can lead to more eating. However, the evidence for this happening in humans is still unproven. <h2>What about inflammation and dental issues?</h2> There is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10817473/">some early evidence</a> artificial sweeteners may irritate the lining of the digestive system, causing inflammation and increasing the likelihood of diarrhoea, constipation, bloating and other symptoms often associated with irritable bowel syndrome. However, this study noted more research is needed. High amounts of diet soft drinks have <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-023-17223-0">also been</a> linked with liver disease, which is based on inflammation. The consumption of diet soft drinks is also <a href="https://link.springer.com/article/10.1007/s40368-019-00458-0#:%7E:text=Diet%20soft%20drinks%20often%20have,2006">associated</a> with dental erosion. Many soft drinks contain phosphoric and citric acid, which can damage your tooth enamel and contribute to dental erosion. <h2>Moderation is key</h2> As with many aspects of nutrition, moderation is key with diet soft drinks. Drinking diet soft drinks occasionally is unlikely to harm your health, but frequent or excessive intake may increase health risks in the longer term. Plain water, infused water, sparkling water, herbal teas or milks remain the best options for hydration.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233438/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Accredited Practising Dietitian and Lecturer, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

3 signs your diet is causing too much muscle loss – and what to do about it

<a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> When trying to lose weight, it’s natural to want to see quick results. So when the number on the scales drops rapidly, it seems like we’re on the right track. But as with many things related to weight loss, there’s a flip side: rapid weight loss can result in a significant loss of muscle mass, as well as fat. So how you can tell if you’re losing too much muscle and what can you do to prevent it? <h2>Why does muscle mass matter?</h2> Muscle is an important factor in determining our metabolic rate: how much energy we burn at rest. This is determined by how much muscle and fat we have. Muscle is more metabolically active than fat, meaning it burns more calories. When we diet to lose weight, we create a calorie deficit, where our bodies don’t get enough energy from the food we eat to meet our energy needs. Our bodies start breaking down our fat and muscle tissue for fuel. A decrease in calorie-burning muscle mass slows our metabolism. This quickly slows the rate at which we lose weight and impacts our ability to maintain our weight long term. <h2>How to tell you’re losing too much muscle</h2> Unfortunately, measuring changes in muscle mass is not easy. The most accurate tool is an enhanced form of X-ray called a dual-energy X-ray absorptiometry (DXA) scan. The scan is primarily used in medicine and research to capture data on weight, body fat, muscle mass and bone density. But while DEXA is becoming more readily available at weight-loss clinics and gyms, it’s not cheap. There are also many “smart” scales available for at home use that promise to provide an accurate reading of muscle mass percentage. However, the accuracy of these scales is questionable. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8122302/">Researchers found</a> the scales tested massively over- or under-estimated fat and muscle mass. Fortunately, there are three free but scientifically backed signs you may be losing too much muscle mass when you’re dieting. <h2>1. You’re losing much more weight than expected each week</h2> Losing a lot of weight rapidly is one of the early signs that your diet is too extreme and you’re losing too much muscle. Rapid weight loss (of more than 1 kilogram per week) results in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5702468/">greater muscle mass loss</a> than slow weight loss. Slow weight loss better preserves muscle mass and often has the added benefit of <a href="https://www.sciencedirect.com/science/article/pii/S0195666312000153">greater fat mass loss</a>. One study compared people in the obese weight category who followed either a very low-calorie diet (500 calories per day) for five weeks or a low-calorie diet (1,250 calories per day) for 12 weeks. While both groups lost similar amounts of weight, participants following the very low-calorie diet (500 calories per day) for five weeks lost <a href="https://pubmed.ncbi.nlm.nih.gov/26813524/">significantly more muscle mass</a>. <h2>2. You’re feeling tired and things feel more difficult</h2> It sounds obvious, but feeling tired, sluggish and finding it hard to complete physical activities, such as working out or doing jobs around the house, is another strong signal you’re losing muscle. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3648712/">Research</a> shows a decrease in muscle mass may negatively impact your body’s physical performance. <h2>3. You’re feeling moody</h2> Mood swings and feeling anxious, stressed or depressed may also be signs you’re losing muscle mass. <a href="https://pubmed.ncbi.nlm.nih.gov/26228522/">Research</a> on muscle loss due to ageing suggests low levels of muscle mass can negatively impact mental health and mood. This seems to stem from the relationship between low muscle mass and proteins called neurotrophins, which help regulate mood and feelings of wellbeing. <h2>So how you can do to maintain muscle during weight loss?</h2> Fortunately, there are also three actions you can take to maintain muscle mass when you’re following a calorie-restricted diet to lose weight. <h2>1. Incorporate strength training into your exercise plan</h2> While a broad exercise program is important to support overall weight loss, strength-building exercises are a surefire way to help prevent the loss of muscle mass. A <a href="https://pubmed.ncbi.nlm.nih.gov/29596307/">meta-analysis of studies</a> of older people with obesity found resistance training was able to prevent almost 100% of muscle loss from calorie restriction. Relying on diet alone to lose weight will reduce muscle along with body fat, slowing your metabolism. So it’s essential to make sure you’ve incorporated sufficient and appropriate exercise into your weight-loss plan to hold onto your muscle mass stores. But you don’t need to hit the gym. Exercises using body weight – such as push-ups, pull-ups, planks and air squats – are just as effective as lifting weights and using strength-building equipment. Encouragingly, moderate-volume resistance training (three sets of ten repetitions for eight exercises) <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/sms.14237">can be as effective</a> as high-volume training (five sets of ten repetitions for eight exercises) for maintaining muscle when you’re following a calorie-restricted diet. <h2>2. Eat more protein</h2> Foods high in protein play an essential role in building and maintaining muscle mass, but <a href="https://europepmc.org/article/MED/19927027">research</a> also shows these foods help prevent muscle loss when you’re following a calorie-restricted diet. But this doesn’t mean just eating foods with protein. Meals need to be balanced and include a source of protein, wholegrain carb and healthy fat to meet our dietary needs. For example, eggs on wholegrain toast with avocado. <h2>3. Slow your weight loss plan down</h2> When we change our diet to lose weight, we take our body out of its comfort zone and trigger its survival response. It then counteracts weight loss, triggering <a href="https://pubmed.ncbi.nlm.nih.gov/25896063/">several physiological responses</a> to defend our body weight and “survive” starvation. Our body’s survival mechanisms want us to regain lost weight to ensure we survive the next period of famine (dieting). <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5764193/">Research</a> shows that more than half of the weight lost by participants is regained within two years, and more than 80% of lost weight is regained within five years. However, a slow and steady, stepped approach to weight loss, prevents our bodies <a href="https://pubmed.ncbi.nlm.nih.gov/38193357/">from activating defence mechanisms</a> to defend our weight when we try to lose weight. Ultimately, losing weight long-term comes down to making gradual changes to your lifestyle to ensure you form habits that last a lifetime. <hr /> At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

What’s the difference between vegan and vegetarian?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Vegan and vegetarian diets are <a href="https://link.springer.com/article/10.1007/s00394-023-03086-z">plant-based diets</a>. Both include plant foods, such as fruits, vegetables, legumes and whole grains. But there are important differences, and knowing what you can and can’t eat when it comes to a vegan and vegetarian diet can be confusing. So, what’s the main difference? <h2>What’s a vegan diet?</h2> A <a href="https://link.springer.com/article/10.1007/s00394-023-03086-z">vegan diet</a> is an entirely plant-based diet. It doesn’t include any meat and animal products. So, no meat, poultry, fish, seafood, eggs, dairy or honey. <h2>What’s a vegetarian diet?</h2> A <a href="https://link.springer.com/article/10.1007/s00394-023-03086-z">vegetarian diet</a> is a plant-based diet that generally excludes meat, poultry, ﬁsh and seafood, but can include animal products. So, unlike a vegan diet, a vegetarian diet can include eggs, dairy and honey. But you may be wondering why you’ve heard of vegetarians who eat fish, vegetarians who don’t eat eggs, vegetarians who don’t eat dairy, and even vegetarians who eat some meat. Well, it’s because there are variations on a vegetarian diet: <ul> <li> a lacto-ovo vegetarian diet excludes meat, poultry, fish and seafood, but includes eggs, dairy and honey </li> <li> an ovo-vegetarian diet excludes meat, poultry, fish, seafood and dairy, but includes eggs and honey </li> <li> a lacto-vegetarian diet excludes meat, poultry, fish, seafood and eggs, but includes dairy and honey </li> <li> a pescatarian diet excludes meat and poultry, but includes eggs, dairy, honey, fish and seafood </li> <li> a flexitarian, or semi-vegetarian diet, includes eggs, dairy and honey and may include small amounts of meat, poultry, fish and seafood. </li> </ul> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=456&fit=crop&dpr=1 600w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=456&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=456&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=573&fit=crop&dpr=1 754w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=573&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=573&fit=crop&dpr=3 2262w" alt="" /></a><figcaption></figcaption></figure> <h2>Are these diets healthy?</h2> A <a href="https://academic.oup.com/eurheartj/article/44/36/3423/7224412">2023 review</a> looked at the health effects of vegetarian and vegan diets from two types of study. Observational studies followed people over the years to see how their diets were linked to their health. In these studies, eating a vegetarian diet was associated with a lower risk of developing cardiovascular disease (such as heart disease or a stroke), diabetes, hypertension (high blood pressure), dementia and cancer. For example, in a <a href="https://www.sciencedirect.com/science/article/pii/S0002916523054497?via%3Dihub">study</a> of 44,561 participants, the risk of heart disease was 32% lower in vegetarians than non-vegetarians after an average follow-up of nearly 12 years. Further evidence came from randomised controlled trials. These instruct study participants to eat a specific diet for a specific period of time and monitor their health throughout. These studies showed eating a vegetarian or vegan diet led to reductions in weight, blood pressure, and levels of unhealthy cholesterol. For example, one <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/1832195">analysis</a> combined data from seven randomised controlled trials. This so-called meta-analysis included data from 311 participants. It showed eating a vegetarian diet was associated with a systolic blood pressure (the first number in your blood pressure reading) an average 5 mmHg lower compared with non-vegetarian diets. It seems vegetarian diets are more likely to be healthier, across a number of measures. For example, a 2022 <a href="https://link.springer.com/article/10.1007/s00394-022-02942-8">meta-analysis</a> combined the results of several observational studies. It concluded a vegetarian diet, rather than vegan diet, was recommended to prevent heart disease. There is also <a href="https://link.springer.com/article/10.1007/s13668-024-00533-z">evidence</a> vegans are more likely to have bone fractures than vegetarians. This could be partly due to a lower body-mass index and a lower intake of nutrients such as calcium, vitamin D and protein. <h2>But it can be about more than just food</h2> Many vegans, where possible, do not use products that directly or indirectly involve using animals. So vegans would not wear leather, wool or silk clothing, for example. And they would not use soaps or candles made from beeswax, or use products tested on animals. The motivation for following a vegan or vegetarian diet can vary from person to person. Common motivations <a href="https://www.sciencedirect.com/science/article/pii/S2475299123157957">include</a> health, environmental, ethical, religious or economic reasons. And for many people who follow a vegan or vegetarian diet, this forms a central part of their <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9231820/">identity</a>. <h2>So, should I adopt a vegan or vegetarian diet?</h2> If you are thinking about a vegan or vegetarian diet, here are some things to consider: <ul> <li> eating more plant foods does not automatically mean you are eating a healthier diet. Hot chips, biscuits and soft drinks can all be vegan or vegetarian foods. And many <a href="https://theconversation.com/we-looked-at-700-plant-based-foods-to-see-how-healthy-they-really-are-heres-what-we-found-222991">plant-based alternatives</a>, such as plant-based sausages, can be high in added salt </li> <li> meeting the <a href="https://www.eatforhealth.gov.au/nutrient-reference-values/nutrients">nutrient intake targets</a> for vitamin B12, iron, calcium, and iodine requires more careful planning while on a vegan or vegetarian diet. This is because meat, seafood and animal products are good sources of these vitamins and minerals </li> <li> eating a plant-based diet doesn’t necessarily mean <a href="https://theconversation.com/why-you-should-eat-a-plant-based-diet-but-that-doesnt-mean-being-a-vegetarian-78470">excluding</a> all meat and animal products.

5 ways your sleep affects what you eat

We know a good night’s sleep is good for us but logging in those hours of sleep can be a difficult task. Without quality shut-eye, our productivity decreases, immune system weakens and even our dietary health is negatively affected. You eat more when you sleep less A Mayo Clinic study comparing the eating habits of people who slept as much as they needed and those who only slept two-thirds of their required rest time for eight days, found the subject who were sleep-deprived ended up eating an average of 549 extra calories each day. You snack more, especially at night A lack of sleep can lead to decrease in physical activity and an increase in snacking behaviour. Such behaviours typically leads to weight gain. You crave extra carbs and fatty foods The foods we’re snacking on aren’t usually the healthy variety. A 2013 study found that when we’re tired we not only crave unhealthy, -carbohydrate, and high-fat foods but we’re less likely to consider the consequences of such food choices over time. Disrupted sleep cycle equal changing eating patterns Your internal clock guides both your sleep patterns and your eating patterns – aka when you feel hungry during the day. A 2011 study found that people who are “late sleepers” tend to delay their meals throughout the day and end up consuming more calories than the average meal. Those late-eating habits affect sleep and perpetuates the cycle. You don’t eat the right foods A 2013 study found that sleep-deprived subjects ate half the fruit and vegetable servings of a normal sleeper. This meant losing key nutrients from their diet, which can lead to dietary imbalances and effect the regular functioning of the body. Image credits: Shutterstock

Want to reduce your dementia risk? Eat these 4 foods, says new study

If you are what you eat, this might make you hungrier for foods that are bright in every sense. Research has shown that living, vibrant foods can slow down aging at a cellular level; while fruit and vegetables in particular have been associated with lower incidence of cognitive decline as individuals age. However, research has been relatively lacking on just how much of these brain-healthy foods you really need and which fruit and vegetables are best for the job. In collaboration with public health experts at Harvard University, medical researchers at China’s Zhejiang University School of Medicine conducted a meta-analysis that’s slated to be published in the June 2024 issue of The Journal of Nutrition, Health, and Aging. They combined data from two large-scale population-representative studies that analysed the diets and cognitive function of more than 10,000 participants ages 55 and older from China and the US. <h2>What daily diets revealed</h2> The data included diet questionnaires that honed in on the average of participants’ total daily intake of several different types of foods, including fruit and vegetables, and also broke them down into sub-types like green leafy vegetables and berries. Over a period of five years, the participants also took part in activities designed to assess their cognitive function and the average rate of cognitive decline. Overall, participants who included the most fruit and vegetables in their daily diets performed best on the brain tests and maintained those results over time. This suggested that both fruit and vegetables had protective elements that slowed cognitive decline. <h2>Vegetables that help protect cognition</h2> Interestingly, certain types of vegetables appeared to be more beneficial than others—say the researchers: “Our findings support the potential beneficial roles of VF, especially cruciferous vegetables, green leafy vegetables, and red and yellow vegetables, in maintaining cognitive function and slowing cognitive decline in middle-aged and older adults.” The researchers pointed to several reasons these particular vegetables might have shown a substantial impact, including anti-inflammatory and antioxidation nutrients like flavonoids and various vitamins or even gut improvements that have been shown to help improve or protect cognition. While beans didn’t figure prominently in both studies, they showed a protective element in the US study, so they are also worth keeping on your plate. (Beans are also thought to be one of the top foods for longevity.) <h2>Fruit that pack a punch</h2> As for fruit, while some didn’t show as much of a protective effect across the board, berries and apples are two examples of fruit that experts have previously said provide major polyphenol and antioxidant effect. Participants whose brains maintained performance were shown to have eaten three or more servings of vegetables and two or more servings of fruit per day. This is on par with the five servings of vegetables and two servings of fruit recommended we eat every day.

Exercise, therapy and diet can all improve life during cancer treatment and boost survival. Here’s how

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/rob-newton-12124">Rob Newton</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> With so many high-profile people <a href="https://www.theguardian.com/uk-news/2024/mar/23/cancer-charities-princess-of-wales-speaking-about-diagnosis">diagnosed with cancer</a> we are confronted with the stark reality the disease can strike any of us at any time. There are also reports certain cancers are <a href="https://www.cancer.org/research/acs-research-news/facts-and-figures-2024.html">increasing among younger people</a> in their 30s and 40s. On the positive side, medical treatments for cancer are advancing very rapidly. Survival rates are <a href="https://acsjournals.onlinelibrary.wiley.com/doi/10.3322/caac.21763">improving greatly</a> and some cancers are now being managed more as <a href="https://www.cancer.org/cancer/survivorship/long-term-health-concerns/cancer-as-a-chronic-illness.html">long-term chronic diseases</a> rather than illnesses that will rapidly claim a patient’s life. The <a href="https://www.cancer.org/cancer/managing-cancer/treatment-types.html">mainstays of cancer treatment</a> remain surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy and hormone therapy. But there are other treatments and strategies – “adjunct” or supportive cancer care – that can have a powerful impact on a patient’s quality of life, survival and experience during cancer treatment. <h2>Keep moving if you can</h2> Physical exercise is now recognised as a <a href="https://www.exerciseismedicine.org/">medicine</a>. It can be tailored to the patient and their health issues to stimulate the body and build an internal environment where <a href="https://wchh.onlinelibrary.wiley.com/doi/full/10.1002/tre.884">cancer is less likely to flourish</a>. It does this in a number of ways. Exercise provides a strong stimulus to our immune system, increasing the number of cancer-fighting immune cells in our blood circulation and infusing these into the tumour tissue <a href="https://jitc.bmj.com/content/9/7/e001872">to identify and kill cancer cells</a>. Our skeletal muscles (those attached to bone for movement) release signalling molecules called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7288608/">myokines</a>. The larger the muscle mass, the more myokines are released – even when a person is at rest. However, during and immediately after bouts of exercise, a further surge of myokines is secreted into the bloodstream. Myokines attach to immune cells, stimulating them to be better “hunter-killers”. Myokines also signal directly to cancer cells <a href="https://www.sciencedirect.com/science/article/pii/S2095254623001175">slowing their growth and causing cell death</a>. Exercise can also greatly <a href="https://wchh.onlinelibrary.wiley.com/doi/full/10.1002/tre.884">reduce the side effects of cancer treatment</a> such as fatigue, muscle and bone loss, and fat gain. And it reduces the risk of <a href="https://doi.org/10.2337/diacare.27.7.1812">developing other chronic diseases</a> such as heart disease and type 2 diabetes. Exercise can maintain or improve quality of life and mental health <a href="https://www.hindawi.com/journals/tbj/2022/9921575/">for patients with cancer</a>. Emerging research evidence indicates exercise might increase the effectiveness of mainstream treatments such as <a href="https://aacrjournals.org/cancerres/article/81/19/4889/670308/Effects-of-Exercise-on-Cancer-Treatment-Efficacy-A">chemotherapy</a> and <a href="https://www.nature.com/articles/s41391-020-0245-z">radiation therapy</a>. Exercise is certainly essential for preparing the patient for any surgery to increase cardio-respiratory fitness, reduce systemic inflammation, and increase muscle mass, strength and physical function, and then <a href="https://www.jsams.org/article/S1440-2440(18)31270-2/fulltext">rehabilitating them after surgery</a>. These mechanisms explain why cancer patients who are physically active have much <a href="https://journals.lww.com/acsm-msse/fulltext/2019/06000/physical_activity_in_cancer_prevention_and.20.aspx">better survival outcomes</a> with the relative risk of death from cancer <a href="https://journals.lww.com/acsm-msse/fulltext/2019/06000/physical_activity_in_cancer_prevention_and.20.aspx">reduced by as much as 40–50%</a>. <h2>Mental health helps</h2> The second “tool” which has a major role in cancer management is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6016045/">psycho-oncology</a>. It involves the psychological, social, behavioural and emotional aspects of cancer for not only the patient but also their carers and family. The aim is to maintain or improve quality of life and mental health aspects such as emotional distress, anxiety, depression, sexual health, coping strategies, personal identity and relationships. Supporting quality of life and happiness is important on their own, but these barometers <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2024.1349880/full">can also impact</a> a patient’s physical health, response to exercise medicine, resilience to disease and to treatments. If a patient is highly distressed or anxious, their body can enter a flight or fight response. This creates an internal environment that is actually supportive of cancer progression <a href="https://www.cancer.gov/about-cancer/coping/feelings/stress-fact-sheet">through hormonal and inflammatory mechanisms</a>. So it’s essential their mental health is supported. <h2>Putting the good things in: diet</h2> A third therapy in the supportive cancer care toolbox is diet. A healthy diet <a href="https://www.cancer.org/cancer/survivorship/coping/nutrition/benefits.html">can support the body</a> to fight cancer and help it tolerate and recover from medical or surgical treatments. Inflammation provides a more fertile environment <a href="https://www.cancer.gov/news-events/cancer-currents-blog/2022/reducing-inflammation-to-treat-cancer">for cancer cells</a>. If a patient is overweight with excessive fat tissue then a diet to reduce fat which is also anti-inflammatory can be very helpful. This <a href="https://www.frontiersin.org/articles/10.3389/fnut.2021.709435/full">generally means</a> avoiding processed foods and eating predominantly fresh food, locally sourced and mostly plant based. Muscle loss is <a href="https://onlinelibrary.wiley.com/doi/10.1002/rco2.56">a side effect of all cancer treatments</a>. Resistance training exercise can help but people may need protein supplements or diet changes to make sure they get enough protein to build muscle. Older age and cancer treatments may reduce both the intake of protein and compromise absorption so <a href="https://www.sciencedirect.com/science/article/pii/S0261561421005422">supplementation may be indicated</a>. Depending on the cancer and treatment, some patients may require highly specialised diet therapy. Some cancers such as pancreatic, stomach, esophageal, and lung cancer can cause rapid and uncontrolled drops in body weight. This is called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8233663/">cachexia and needs careful management</a>. Other cancers and treatments such as hormone therapy can cause rapid weight gain. This also needs careful monitoring and guidance so that, when a patient is clear of cancer, they are not left with higher risks of other health problems such as cardiovascular disease and metabolic syndrome (a cluster of conditions that boost your risk of heart disease, stroke and type 2 diabetes). <h2>Working as a team</h2> These are three of the most powerful tools in the supportive care toolbox for people with cancer. None of them are “cures” for cancer, alone or together. But they can work in tandem with medical treatments to greatly improve outcomes for patients. If you or someone you care about has cancer, national and state cancer councils and cancer-specific organisations can provide support. For exercise medicine support it is best to consult with an <a href="https://www.essa.org.au/Public/Public/Consumer_Information/What_is_an_Accredited_Exercise_Physiologist_.aspx">accredited exercise physiologist</a>, for diet therapy an <a href="https://dietitiansaustralia.org.au/working-dietetics/standards-and-scope/role-accredited-practising-dietitian">accredited practising dietitian</a> and mental health support with a <a href="https://psychology.org.au/psychology/about-psychology/what-is-psychology">registered psychologist</a>. Some of these services are supported through Medicare on referral from a general practitioner. <hr /> For free and confidential cancer support call the <a href="https://www.cancer.org.au/support-and-services/cancer-council-13-11-20">Cancer Council</a> on 13 11 20.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/226720/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rob-newton-12124">Rob Newton</a>, Professor of Exercise Medicine, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Caring

Not all ultra-processed foods are bad for your health, whatever you might have heard

<a href="https://theconversation.com/profiles/gary-sacks-3957">Gary Sacks</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-backholer-10739">Kathryn Backholer</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-bradbury-1532662">Kathryn Bradbury</a>, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a>, and <a href="https://theconversation.com/profiles/sally-mackay-1532685">Sally Mackay</a>, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a> In recent years, there’s been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11036430/">increasing</a> <a href="https://theconversation.com/ultra-processed-foods-heres-what-the-evidence-actually-says-about-them-220255#:%7E:text=Hype%20around%20ultra%2Dprocessed%20food,or%20worry%20about%20their%20health.">hype</a> about the potential health risks associated with so-called “ultra-processed” foods. But new evidence published <a href="https://www.bmj.com/content/385/bmj-2023-078476">this week</a> found not all “ultra-processed” foods are linked to poor health. That includes the mass-produced wholegrain bread you buy from the supermarket. While this newly published research and associated <a href="https://www.bmj.com/content/385/bmj.q793">editorial</a> are unlikely to end the wrangling about how best to define unhealthy foods and diets, it’s critical those debates don’t delay the implementation of policies that are likely to actually improve our diets. <h2>What are ultra-processed foods?</h2> <a href="https://pubmed.ncbi.nlm.nih.gov/30744710/">Ultra-processed foods</a> are industrially produced using a variety of processing techniques. They typically include ingredients that can’t be found in a home kitchen, such as preservatives, emulsifiers, sweeteners and/or artificial colours. Common examples of ultra-processed foods include packaged chips, flavoured yoghurts, soft drinks, sausages and mass-produced packaged wholegrain bread. In <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7719194/#CR13">many other countries</a>, ultra-processed foods make up a large proportion of what people eat. A <a href="https://pubmed.ncbi.nlm.nih.gov/31676952/">recent study</a> estimated they make up an average of 42% of total energy intake in Australia. <h2>How do ultra-processed foods affect our health?</h2> Previous <a href="https://pubmed.ncbi.nlm.nih.gov/33167080/">studies</a> have linked increased consumption of ultra-processed food with poorer health. High consumption of ultra-processed food, for example, has been associated with a <a href="https://pubmed.ncbi.nlm.nih.gov/38418082/">higher risk</a> of type 2 diabetes, and death from heart disease and stroke. Ultra-processed foods are typically high in energy, added sugars, salt and/or unhealthy fats. These have long been <a href="https://www.who.int/news-room/fact-sheets/detail/healthy-diet">recognised</a> as risk factors for a range of diseases. It has also been suggested that structural changes that happen to ultra-processed foods as part of the manufacturing process <a href="https://pubmed.ncbi.nlm.nih.gov/31105044/">may</a> lead you to eat more than you should. Potential explanations are that, due to the way they’re made, the foods are quicker to eat and more palatable. It’s also <a href="https://pubmed.ncbi.nlm.nih.gov/35952706/">possible</a> certain food additives may impair normal body functions, such as the way our cells reproduce. <h2>Is it harmful? It depends on the food’s nutrients</h2> The <a href="https://www.bmj.com/content/385/bmj-2023-078476">new paper</a> just published used 30 years of data from two large US cohort studies to evaluate the relationship between ultra-processed food consumption and long-term health. The study tried to disentangle the effects of the manufacturing process itself from the nutrient profile of foods. The study found a small increase in the risk of early death with higher ultra-processed food consumption. But importantly, the authors also looked at diet quality. They found that for people who had high quality diets (high in fruit, vegetables, wholegrains, as well as healthy fats, and low in sugary drinks, salt, and red and processed meat), there was no clear association between the amount of ultra-processed food they ate and risk of premature death. This suggests overall diet quality has a stronger influence on long-term health than ultra-processed food consumption. When the researchers analysed ultra-processed foods by sub-category, mass-produced wholegrain products, such as supermarket wholegrain breads and wholegrain breakfast cereals, were not associated with poorer health. This finding matches another recent <a href="https://pubmed.ncbi.nlm.nih.gov/38417577/">study</a> that suggests ultra-processed wholegrain foods are not a driver of poor health. The authors concluded, while there was some support for limiting consumption of certain types of ultra-processed food for long-term health, not all ultra-processed food products should be universally restricted. <h2>Should dietary guidelines advise against ultra-processed foods?</h2> Existing national <a href="https://www.eatforhealth.gov.au/sites/default/files/2022-09/n55_australian_dietary_guidelines.pdf">dietary</a> <a href="https://www.health.govt.nz/system/files/documents/publications/eating-activity-guidelines-new-zealand-adults-updated-2020-oct22.pdf">guidelines</a> have been developed and refined based on decades of nutrition evidence. Much of the recent evidence related to ultra-processed foods tells us what we already knew: that products like soft drinks, alcohol and processed meats are bad for health. Dietary guidelines <a href="https://pubmed.ncbi.nlm.nih.gov/35184508/">generally</a> already advise to eat mostly whole foods and to limit consumption of highly processed foods that are high in refined grains, saturated fat, sugar and salt. But some nutrition researchers have <a href="https://www.bmj.com/content/384/bmj.q439">called</a> for dietary guidelines to be amended to recommend avoiding ultra-processed foods. Based on the available evidence, it would be difficult to justify adding a sweeping statement about avoiding all ultra-processed foods. Advice to avoid all ultra-processed foods would likely unfairly impact people on low-incomes, as many ultra-processed foods, such as supermarket breads, are relatively affordable and convenient. Wholegrain breads also provide important nutrients, such as fibre. In many countries, bread is the <a href="https://www.health.govt.nz/system/files/documents/publications/a-focus-on-nutrition-ch3_0.pdf">biggest contributor</a> to fibre intake. So it would be problematic to recommend avoiding supermarket wholegrain bread just because it’s ultra-processed. <h2>So how can we improve our diets?</h2> There is strong <a href="https://www.foodpolicyindex.org.au/_files/ugd/7ee332_a2fa1694e42f423195caf581044fccf1.pdf">consensus</a> on the need to implement evidence-based policies to improve population diets. This includes legislation to restrict children’s exposure to the marketing of unhealthy foods and brands, mandatory Health Star Rating nutrition labelling and taxes on sugary drinks. These policies are underpinned by <a href="https://pubmed.ncbi.nlm.nih.gov/37659696/">well-established systems</a> for classifying the healthiness of foods. If new evidence unfolds about mechanisms by which ultra-processed foods drive health harms, these classification systems can be updated to reflect such evidence. If specific additives are found to be harmful to health, for example, this evidence can be incorporated into existing nutrient profiling systems, such as the <a href="http://www.healthstarrating.gov.au/internet/healthstarrating/publishing.nsf/content/home">Health Star Rating</a> food labelling scheme. Accordingly, policymakers can confidently progress food policy implementation using the tools for classifying the healthiness of foods that we already have. Unhealthy diets and obesity are among the <a href="https://www.aihw.gov.au/reports/burden-of-disease/burden-of-disease-study-2018-key-findings/contents/key-findings">largest contributors</a> to poor health. We can’t let the hype and academic debate around “ultra-processed” foods delay implementation of globally recommended policies for improving population diets.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229493/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/gary-sacks-3957">Gary Sacks</a>, Professor of Public Health Policy, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-backholer-10739">Kathryn Backholer</a>, Co-Director, Global Centre for Preventive Health and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-bradbury-1532662">Kathryn Bradbury</a>, Senior Research Fellow in the School of Population Health, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a>, and <a href="https://theconversation.com/profiles/sally-mackay-1532685">Sally Mackay</a>, Senior Lecturer Epidemiology and Biostatistics, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Food & Wine

How extreme dieting can affect bone health

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> In a recent Instagram post, the actor Jameela Jamil revealed she has poor bone density, despite only being in her 30s. Jamil blamed this finding on 20 years of dieting – urging her followers to be aware of the harms diet culture can do to your health. Bone density is important for many reasons, primarily because it acts as a reservoir for many of the important minerals our bones need to function well. Many factors can affect your bone density – and as Jamil has pointed out, diet is one component that has a significant effect on bone health. Bone is a living tissue. This means our skeleton <a href="https://www.sciencedirect.com/science/article/abs/pii/S1521690X08000869">grows and remodels itself</a> according to the stresses and strains it’s put under. Everything from fractures to exercise require our bones to change their shape or density. This is why a weightlifter’s skeleton is <a href="https://link.springer.com/article/10.1007/BF00298721">much denser</a> than a marathon runner’s. The biggest skeletal changes we experience happen in our younger years. But bones keep changing throughout our lives depending on how active we are, what our diet consists of, and if we’ve suffered an injury or disease. Bones are <a href="https://www.niams.nih.gov/health-topics/what-bone">made of proteins</a>, such as collagen, as well as minerals – largely calcium. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK430714/">key mineral</a> for us, as it keeps our bones and teeth strong and helps repair and rebuild any injured bones. But other minerals and vitamins are also important. For example, vitamin D supports calcium, playing a key role in <a href="https://jamanetwork.com/journals/jamapediatrics/fullarticle/2761808">bone mineralisation</a>. This is where calcium <a href="https://www.ncbi.nlm.nih.gov/books/NBK279023/">combines with phosphate</a> in our bones to create the mineral crystal <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7264100/">hydroxyapatite</a>. This crystal is crucial to our bone mineral density (also known as “bone mass”), as it helps bones remodel and maintain their structural strength. <a href="https://www.nhs.uk/conditions/dexa-scan/">Dexa scans</a> – the type of scan Jamil referred to in her post – can measure the density of these crystals in bones. The <a href="https://theros.org.uk/information-and-support/osteoporosis/scans-tests-and-results/bone-density-scan-dxa/">more hydroxyapatite crystals</a> detected, the healthier the bones are. <figure class="align-center "><img src="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=338&fit=crop&dpr=1 600w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=338&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=338&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=424&fit=crop&dpr=1 754w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=424&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=424&fit=crop&dpr=3 2262w" alt="The interior of bones, showing four depictions of bone density – from healthy to severe osteoporosis." /><figcaption>The more crystals detected, the better your bone density. <a class="source" href="https://www.shutterstock.com/image-illustration/osteoporosis-4-stages-one-picture-3d-524364046">Crevis/ Shutterstock</a></figcaption></figure> We hit peak bone mineral density in our <a href="https://pubmed.ncbi.nlm.nih.gov/35869910/">late teens and early 20s</a>, when our body has grown to full size and our metabolism is working its best. From here, it’s possible to maintain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">stable bone mass</a> into your late 30s for women and early 40s for men, with the right diet and activity. But after this point, it begins to decline. <h2>Bone density</h2> We accrue calcium over many years. It initially comes from our mother, then later from our diet. Our body accrues calcium so it can adapt to times when calcium demand is greater than what we can get from our diet – such as during pregnancy, when the foetus needs calcium to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3355895/">build its own bones</a>. However, relying solely on this skeletal calcium reserve can’t be sustained for lengthy or repeated periods, because of how long it takes to be replenished. This is why diet is so important for bone density – and why a poor diet can cause extreme damage, especially when certain food groups or minerals are consistently left out. For instance, studies have shown consuming soft drinks, (<a href="https://pubmed.ncbi.nlm.nih.gov/17023723/">particularly cola</a>), more than four times a week is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071508/">lower bone density</a> and increased fracture risk. This is true even after adjusting for many other variables that affect bone density. These carbonated and energy drinks contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2966367/">varying levels of vitamins</a> – often with none of the minerals, including calcium, that the body needs to function optimally. This causes the body to draw on its reserves if calcium isn’t being delivered elsewhere in the diet. Diets high in added sugar can also have a detrimental affect on the skeleton. Excess sugar causes inflammation and other physiological changes, such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9471313/">obesity</a>. Consuming high amounts of sugar is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2748414/">reduced calcium intake</a>, especially in children who substitute milk for sugary drinks. Excess sugar consumption also causes the body to <a href="https://jps.biomedcentral.com/articles/10.1007/s12576-016-0487-7">excrete excess calcium</a>, instead of reabsorbing it in the kidney as the body normally would. <a href="https://pubmed.ncbi.nlm.nih.gov/25491765/">Low- and high-fat diets</a> have also been associated with increased risk of <a href="https://www.nhs.uk/conditions/osteoporosis/">osteoporosis</a> (a condition that weakens bones) in women – though larger studies are needed to better understand the effects of removing whole food groups on bone health. <a href="https://www.nhs.uk/mental-health/conditions/anorexia/overview/">Anorexia nervosa</a> also has a significant affect on <a href="https://pubmed.ncbi.nlm.nih.gov/30817009">bone density</a> – affecting a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">majority of people</a> with the condition. Low bone mineral density – especially in the spine – puts people with anorexia at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">increased risk of fractures</a> because their bone thickness is reduced, increasing the likelihood of developing osteoporosis, which is associated with increased fractures. Anorexia in young adulthood is particularly challenging. This is the stage where the skeleton is building itself to reach peak <a href="https://pubmed.ncbi.nlm.nih.gov/15574617/">bone mass</a>, so it’s depositing calcium at a record pace. When diet is insufficient and the body already starts drawing on its mineral reserves, there’s a potential that the bone density or calcium reserves in the body will never be optimal – increasing fracture risk for the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6746661/">rest of that person’s life</a>. <h2>Can bone health be fixed?</h2> Optimal bone health starts in utero, but our prepubescent years are key to <a href="https://pubmed.ncbi.nlm.nih.gov/26884506/">setting our skeleton up</a> for later life. People who are behind the curve in early life may have difficulty achieving their peak, as poor bone mineral density can affect everything from our appetite to how efficient our gastrointestinal tract is at absorbing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6971894/">important nutrients</a> (including calcium). Supplements have a limited effect because our body can only absorb a set amount of any <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8746734/">vitamin or mineral at a time</a>. While it’s possible to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">limit some of the decline</a> in bone density that naturally happens as we age, some of the choices we make – such as not consuming enough calcium – can accelerate the decline. Biological sex also has a significant impact on our bone health in old age – with post-menopausal women at greater risk of osteoporosis because they <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5643776/">produce less oestrogen</a>, which helps keep the cells that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3424385">degrade bone</a> in check.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/228321/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Don’t give mum chocolates for Mother’s Day. Take on more housework, share the mental load and advocate for equality instead

<a href="https://theconversation.com/profiles/leah-ruppanner-106371">Leah Ruppanner</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> With Mother’s Day right around the corner, many grateful and loving families are thinking about what to give mum to show their appreciation. Should you give her chocolate? Nope. Fancy soaps? Nope. Fuzzy slippers, pyjamas, scented candles? No, no and no. On this Mother’s Day, keep your cash and give your wonderful mother gifts that will actually have a long-term impact on her health and well-being. <h2>1. Do a chore that mum hates and hold onto it … forever</h2> Research <a href="https://www.tandfonline.com/doi/full/10.1080/13545701.2020.1831039">shows</a> men have increased the amount of time spent on housework and childcare and that mothers, over time, are doing less (hooray!). But, women <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1741-3737.2008.00479.x">still do more housework</a> than men, especially when <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/gwao.12497?fbclid=IwAR2dp04p2sFqbDqdehXmXgDSfTYwX3GRzP7ScMJhSOrMePTGQVErR2TTX88">kids are in the home</a>. Further, <a href="https://journals.sagepub.com/doi/abs/10.1177/0891243205285212">men tend to pick up the more desirable tasks</a>, like <a href="https://www.jstor.org/stable/3598304">cooking and playing with the kids</a>, leaving mothers to do the less pleasurable chores (think cleaning toilets and clearing out fridges). The chore divide in same-sex relationships is generally found to be more equal, but some critique suggests equality may suffer <a href="https://www.nytimes.com/2018/05/16/upshot/same-sex-couples-divide-chores-much-more-evenly-until-they-become-parents.html">once kids are involved</a>. This year give your mum (or mums) the gift of equal housework and childcare sharing – start by taking the most-hated tasks and then hold onto them… forever. <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/gwao.12727">Research</a> shows housework inequality is bad for women’s mental health. Undervaluing women’s housework and unequal sharing of the chores deteriorates <a href="https://link.springer.com/article/10.1007/s11199-022-01282-5">relationship quality</a>, and <a href="https://journals.sagepub.com/doi/full/10.1177/0038038516674664">leads to divorce</a>. Housework and childcare take up valuable time to keep the family happy, harmonious and thriving, often at the expense of mum’s health and well-being. So, skip the chocolates and show mum love by doing the worst, most drudgerous and constant household chores (hello, cleaning mouldy showers!) and keep doing these… forever. <h2>2. Initiate a mental unload</h2> The <a href="https://www.abc.net.au/news/health/2017-09-14/the-mental-load-and-what-to-do-about-it/8942032">mental load</a> is all of the planning, organising and management work necessary to keep the family running. The mental load is often perceived as list making or allocating tasks to family members. But, it’s so much more – it is the <a href="https://theconversation.com/planning-stress-and-worry-put-the-mental-load-on-mothers-will-2022-be-the-year-they-share-the-burden-172599">emotional work</a> that goes with this thinking work. The mental load is the worry work that never ends and can be done <a href="https://www.tandfonline.com/doi/abs/10.1080/13668803.2021.2002813">anywhere, anytime and with anyone</a> (in, for example, said mouldy shower). Because the mental load is performed inside our heads, it is invisible. That means we don’t know when we or others are performing this labour unless we really tune in. In fact, it is often when we tune in through quiet time, relaxation or meditation that the mental load rears its ugly head. Suddenly you remind yourself to buy oranges for the weekend soccer game, organise a family movie night and don’t forget to check in on nanna. Women in heterosexual relationships are <a href="https://journals.sagepub.com/doi/abs/10.1177/0003122419859007">shown to do more</a> of the mental load with serious consequences for their mental health. But we don’t have a comprehensive measurement of how much women do it nor how it is allocated in same-sex couples. So, on this mothers’ day spend some time talking about, cataloguing, and equalising the family’s mental load. This isn’t just making a list about what has to be done but also understanding <a href="https://www.abc.net.au/news/health/2017-09-14/the-mental-load-and-what-to-do-about-it/8942032">how the mental load</a> connects to the emotional health of the family, and the person carrying this <a href="https://www.newamerica.org/better-life-lab/blog/making-the-mental-load-visible/">invisible labour, worry and stress</a>. <h2>3. Speak up for your mum and all caregivers</h2> Families alone cannot bear the brunt of the caregiving necessary to keep us thriving. Governments, workplaces and local communities also play a critical role. For this mothers’ day, pick an issue impacting mothers (for example, equal pay, affordable childcare or paid family leave) and do one thing to help move the needle. Write a letter to your boss, your local MP, or donate money to an advocacy organisation advancing gender equality. Or, role model these behaviours yourself – normalise caregiving as a critical piece of being an effective worker, create policies and practices that support junior staff to care for themselves, their families and their communities and use these policies. <a href="https://journals.sagepub.com/doi/abs/10.1177/0891243216649946">Research</a> shows men want to be equal carers and sharers but often fear what taking time off for caregiving will signal to their employer despite evidence that fathers who request flexible work are perceived more <a href="https://academic.oup.com/sf/article-abstract/94/4/1567/2461609?login=false">favourably</a>. Appearing to be singularly devoted to work was shown to be impossible during the pandemic with kids, spouses, partners, and pets home all day long. Learning to create more care-inclusive workplaces and communities is critical. Paid parental leave, affordable and accessible high-quality childcare, flexibility in how, when and where we work and greater investments in paid sick leave, long-term disability support and aged care are just a few policies that would strengthen the care safety net. We will all be called upon to care at some point in our lives – let’s create the environments that support caregiving for all, not just mum.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/182330/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/leah-ruppanner-106371">Leah Ruppanner</a>, Professor of Sociology and Founding Director of The Future of Work Lab, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

People in the world’s ‘blue zones’ live longer – their diet could hold the key to why

<a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Ageing is an inevitable part of life, which may explain our <a href="https://time.com/4672969/why-do-people-want-to-live-so-long/">strong fascination</a> with the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2726954">quest for longevity</a>. The allure of <a href="https://pubmed.ncbi.nlm.nih.gov/26566891/">eternal youth</a> drives a <a href="https://www.alliedmarketresearch.com/longevity-and-anti-senescence-therapy-market-A14010">multi-billion pound industry</a> ranging from anti-ageing products, supplements and <a href="https://www.everydayhealth.com/diet-nutrition/longevity-diet">diets</a> for those hoping to extend their lifespan. f you look back to the turn of the 20th century, average life expectancy in the UK was around 46 years. Today, it’s closer to <a href="https://population.un.org/wpp/">82 years</a>. We are in fact <a href="https://pubmed.ncbi.nlm.nih.gov/27706136/">living longer than ever before</a>, possibly due to medical advancements and improved <a href="https://www.health.org.uk/publications/reports/mortality-and-life-expectancy-trends-in-the-uk">living and working conditions</a>. But living longer has also come at a price. We’re now seeing higher rates of <a href="https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death">chronic and degenerative diseases</a> – with heart disease consistently topping the list. So while we’re fascinated by what may help us live longer, maybe we should be more interested in being healthier for longer. Improving our “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4632858/">healthy life expectancy</a>” remains a global challenge. Interestingly, certain locations around the world have been discovered where there are a high proportion of centenarians who display remarkable physical and mental health. The <a href="https://pubmed.ncbi.nlm.nih.gov/15489066/">AKEA study of Sardinia, Italy</a>, as example, identified a “blue zone” (named because it was marked with blue pen), where there was a higher number of locals living in the central-eastern mountainous areas who had reached their 100th birthday compared with the wider Sardinian community. This longevity hotspot has since been expanded, and now includes several other areas around the world which also have greater numbers of longer-living, healthy people. Alongside Sardinia, these blue zones are now <a href="https://www.netflix.com/gb/title/81214929">popularly recognised</a> as: Ikaria, Greece; Okinawa, Japan; Nicoya, Costa Rica; and Loma Linda, California. Other than their long lifespans, people living in these zones also appear to share certain other commonalities, which centre around being <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874460">part of a community</a>, having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224996/">life purpose</a>, eating <a href="https://pubmed.ncbi.nlm.nih.gov/33514872/">nutritious, healthy foods</a>, keeping <a href="https://www.nature.com/articles/s41398-021-01735-7">stress levels</a> low and undertaking purposeful daily <a href="https://pubmed.ncbi.nlm.nih.gov/30202288/">exercise or physical tasks</a>. Their longevity could also relate to their <a href="https://pubmed.ncbi.nlm.nih.gov/9010380/">environment</a>, being mostly rural (or less polluted), or because of <a href="https://pubmed.ncbi.nlm.nih.gov/22253498/">specific longevity genes</a>. However, studies indicate genetics may only account for <a href="https://pubmed.ncbi.nlm.nih.gov/8786073">around 20-25% of longevity</a> – meaning a person’s lifespan is a complex interaction between lifestyle and genetic factors, which contribute to a long and healthy life. <h2>Is the secret in our diet?</h2> When it comes to diet, each blue zone has its own approach – so one specific food or nutrient does not explain the remarkable longevity observed. But interestingly, a diet rich in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662288">plant foods</a> (such as locally-grown vegetables, fruits and legumes) does appear to be reasonably consistent across these zones. For instance, the Seventh-day Adventists of Loma Linda are <a href="https://pubmed.ncbi.nlm.nih.gov/10641813/">predominately vegetarian</a>. For centenarians in Okinawa, <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">high intakes of flavonoids</a> (a chemical compound typically found in plants) from purple sweet potatoes, soy and vegetables, have been linked with <a href="https://pubmed.ncbi.nlm.nih.gov/11710359/">better cardiovascular health</a> – including lower cholesterol levels and lower incidences of stroke and heart disease. In Nicoya, consumption of locally produced rice and beans has been associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34444746/">longer telomere length</a>. Telomeres are the structural part at the end of our chromosomes which protect our genetic material. Our telomeres get shorter each time a cell divides – so get progressively shorter as we age. Certain <a href="https://pubmed.ncbi.nlm.nih.gov/21102320/">lifestyle factors</a> (such as smoking and poor diet) can also shorten telomere length. It’s thought that telomere length acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/31728493/">biomarker of ageing</a> – so having longer telomeres could, in part, be linked with longevity. But a plant-based diet isn’t the only secret. In Sardinia, for example, meat and fish is consumed in moderation in addition to locally grown vegetables and <a href="https://journalofethnicfoods.biomedcentral.com/articles/10.1186/s42779-022-00152-5">traditional foods</a> such as acorn breads, pane carasau (a sourdough flatbread), honey and soft cheeses. Also observed in several blue zone areas is the inclusion of <a href="https://www.jacc.org/doi/10.1016/j.jacc.2021.10.041">olive oil</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/33669360/">wine</a> (in moderation – around 1-2 glasses a day), as well as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830687/">tea</a>. All of these contain powerful antioxidants which may help <a href="https://ncbi.nlm.nih.gov/pmc/articles/PMC10049696/">protect our cells</a> from damage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273542/">as we age</a>. Perhaps then, it’s a combination of the protective effects of various nutrients in the diets of these centenarians, which explains their exceptional longevity. Another striking observation from these longevity hot spots is that meals are typically <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7232892">freshly prepared at home</a>. Traditional blue zone diets also don’t appear to contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6538973/">ultra-processed foods</a>, fast foods or sugary drinks which may <a href="https://pubmed.ncbi.nlm.nih.gov/32330232/">accelerate ageing</a>. So maybe it’s just as important to consider what these longer-living populations are not doing, as much as what they are doing. There also appears to be a pattern of eating until 80% full (in other words partial <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9036399/">caloric reduction</a>. This could be important in also supporting how our cells deal with damage as we age, which could mean a longer life. Many of the factors making up these blue zone diets – primarily plant-based and natural whole foods – are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35706591/">lower risk of chronic diseases</a> such as <a href="https://pubmed.ncbi.nlm.nih.gov/28728684/">heart disease</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/37589638/">cancer</a>. Not only could such diets contribute to a <a href="https://pubmed.ncbi.nlm.nih.gov/37836577/">longer, healthier life</a>, but could support a more <a href="https://pubmed.ncbi.nlm.nih.gov/33397404/">diverse gut microbiome</a>, which is also associated with healthy ageing. Perhaps then we can learn something from these remarkable centenarians. While diet is only one part of the bigger picture when it comes to longevity, it’s an area we can do something about. In fact, it might just be at the heart of improving not only the quality of our health, but the quality of how we age.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221463/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, Professor of Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, PhD Candidate in Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, Senior Lecturer in Public Health and Nutrition, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Food & Wine

Eating some chocolate really might be good for you – here’s what the research says

<a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Although it always makes me scoff slightly to see Easter eggs making their first appearance in supermarkets at the end of December, there are few people who aren’t delighted to receive a bit of chocolate every year. It makes sense that too much chocolate would be bad for you because of the high fat and sugar content in most products. But what should we make of common claims that eating some chocolate is actually good for you? Happily, there is a fair amount of evidence that shows, in the right circumstances, chocolate may be both beneficial for your heart and good for your mental state. In fact, chocolate – or more specifically cacao, the raw, unrefined bean – is a medicinal wonder. It contains many different active compounds which can evoke pharmacological effects within the body, like medicines or drugs. Compounds that lead to neurological effects in the brain have to be able to cross the <a href="https://link.springer.com/chapter/10.1007/978-3-642-13443-2_7">blood-brain barrier</a>, the protective shield which prevents harmful substances – like toxins and bacteria – entering the delicate nervous tissue. One of these is the compound <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">theobromine</a>, which is also found in tea and contributes towards its bitter taste. Tea and chocolate also contain caffeine, which theobromine is related to as part of the purine family of chemicals. These chemicals, among others, contribute to chocolate’s addictive nature. They have the ability to cross the blood-brain barrier, where they can influence the nervous system. They are therefore known as <a href="https://pubmed.ncbi.nlm.nih.gov/15549276/">psychoactive</a> chemicals. <figure><iframe src="https://www.youtube.com/embed/HloqayQdR6M?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> What effects can chocolate have on mood? Well, <a href="https://academic.oup.com/nutritionreviews/article/71/10/665/1931144?login=false">a systematic review</a> looked at a group of studies which examined the feelings and emotions associated with consuming chocolate. Most demonstrated improvements in mood, anxiety, energy and states of arousal. Some noted the feeling of guilt, which is perhaps something we’ve all felt after one too many Dairy Milks. <h2>Health benefits of cocoa</h2> There are other organs, aside from the brain, that might benefit from the medicinal effects of cocoa. For centuries, chocolate has been used as a medicine to treat a <a href="https://pubmed.ncbi.nlm.nih.gov/10917925/">long list of diseases</a> including anaemia, tuberculosis, gout and even low libido. These might be spurious claims but there is evidence to suggest that eating cacao has a positive effect on the cardiovascular system. First, it can prevent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8068178/">endothelial dysfunction</a>. This is the process through which arteries harden and get laden down with fatty plaques, which can in turn lead to heart attacks and strokes. Eating dark chocolate may also reduce <a href="https://www.sciencedirect.com/science/article/pii/S1537189115001135?via%3Dihub">blood pressure</a>, which is another risk factor for developing arterial disease, and prevent formation of clots which block up blood vessels. <figure><iframe src="https://www.youtube.com/embed/8VUcPCbSSCY?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Some studies have suggested that dark chocolate might be useful in adjusting ratios of <a href="https://pubmed.ncbi.nlm.nih.gov/20968113/">high-density lipoprotein cholesterol</a>, which can help protect the heart. Others have examined insulin resistance, the phenomenon associated with Type 2 diabetes and weight gain. They suggest that the <a href="https://www.sciencedirect.com/science/article/pii/S0963996900000697#:%7E:text=Cocoa%20is%20rich%20in%20polyphenols%20particularly%20in%20catechins,and%20cocoa%20powder%20have%20been%20published%20only%20recently.">polyphenols</a> – chemical compounds present in plants – found in foodstuffs like chocolate may also lead to <a href="https://pubmed.ncbi.nlm.nih.gov/29993262/">improved control of blood sugars</a>. <h2>Chocolate toxicity</h2> As much as chocolate might be considered a medicine for some, it can be a poison for others. It’s well documented that the ingestion of caffeine and theobromine is highly toxic for domestic animals. Dogs are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4801869/">particularly affected</a> because of their often voracious appetites and generally unfussy natures. The culprit is often dark chocolate, which can provoke symptoms of agitation, rigid muscles and even seizures. In certain cases, if ingested in high enough quantities, it can lead to comas and abnormal, even fatal heart rhythms. Some of the compounds found in chocolate have also been found to have potentially negative effects in humans. Chocolate is a source of oxalate which, along with calcium, is one of the main components of <a href="https://pubmed.ncbi.nlm.nih.gov/20301742/">kidney stones</a>. Some clinical groups have advised against consuming oxalate rich foods, such as spinach and rhubarb – and chocolate, for those who suffer from recurrent kidney stones. So, what should all this mean for our chocolate consumption habits? Science points in the direction of chocolate that has as high a cocoa solid content as possible, and the minimum of extras. The potentially harmful effects of chocolate are more related to fat and sugar, and may counteract any possible benefits. A daily dose of 20g-30g of plain or dark chocolate with cocoa solids above 70% – rather than milk chocolate, which contains fewer solids and white chocolate, which contains none – could lead to a greater health benefit, as well as a greater high. But whatever chocolate you go for, please don’t share it with the dog.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/226759/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, Senior Lecturer, School of Physiology, Pharmacology and Neuroscience, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Here’s why having chocolate can make you feel great or a bit sick – plus 4 tips for better eating

<a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Australians are <a href="https://www.retail.org.au/media/sweet-spending-boon-predicted-for-easter-retail">predicted</a> to spend around A$1.7 billion on chocolates, hot cross buns and other special foods this Easter season. Chocolate has a long history of production and consumption. It is made from cacao beans that go through processes including fermentation, drying, roasting and grounding. What is left is a rich and fatty liquor that is pressed to remove the fat (cocoa butter) and the cacao (or “cocoa”) powder which will then be mixed with different ingredients to produce dark, milk, white and other types of chocolates. There are several health benefits and potential problems that come in these sweet chocolatey packages. <h2>The good news</h2> Cacao beans contain <a href="https://foodstruct.com/food/cocoa-bean">minerals</a> like iron, potassium, magnesium, zinc and phosphorus and some vitamins. They are also rich in beneficial chemicals called <a href="https://pubmed.ncbi.nlm.nih.gov/23150750/">polyphenols</a>. These are great antioxidants, with the potential to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">improve heart health</a>, increase <a href="https://pubmed.ncbi.nlm.nih.gov/25164923/">nitric oxide</a> (which dilates blood vessels) and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3488419/">reduce blood pressure</a>, provide food for gut microbiota and <a href="https://www.mdpi.com/2072-6643/12/7/1908">promote gut health</a>, boost the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">immune system</a> and reduce inflammation. However, the concentration of polyphenols in the chocolate we eat depends largely on the cocoa solid amounts used in the final product. In general terms, the darker the chocolate, the more cocoa solids, minerals and polyphenols it has. For example, dark chocolates may have around <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">seven times more polyphenols</a> compared to white chocolates and <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">three times more polyphenols</a> compared to milk chocolates. <h2>But also some bad news</h2> Unfortunately, the <a href="https://theconversation.com/treat-or-treatment-chocolate-is-good-but-cocoa-is-better-for-your-heart-3084">health benefits of cocoa solids</a> are easily offset by the high sugar and fat content of modern-day chocolates. For example, milk and white chocolate eggs are on average 50% sugar, 40% fat (mostly saturated fats) – which means a lot of added kilojoules (calories). Also, there may be some side effects that come with ingesting chocolate. Cocoa beans include a compound called theobromine. While it has the anti-inflammatory properties responsible for some of the health benefits of chocolate, it is also a mild brain stimulant that acts in a similar way to caffeine. The mood boost it offers may also be partly responsible for how much we <a href="https://www.frontiersin.org/articles/10.3389/fphar.2015.00030/full?crsi=662496658&cicada_org_src=healthwebmagazine.com&cicada_org_mdm=direct">like chocolate</a>. Dark chocolate has higher theobromine compared to milk and white chocolate. But accordingly, overindulging in chocolate (and therefore theobromine) may lead to feeling restless, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">headaches</a> and nausea. <h2>What else is in your chocolate?</h2> Milk and dairy-based chocolates may also cause stomach upset, abdominal pain and bloating in people with <a href="https://dietitiansaustralia.org.au/health-advice/lactose-intolerance">lactose intolerance</a>. This happens when we don’t produce enough lactase enzymes to digest milk sugar (lactose). People with lactose intolerance can usually tolerate up to 6 grams of lactose without showing symptoms. Milk chocolate can have around <a href="https://www.ncbi.nlm.nih.gov/books/NBK310258/">3 grams of lactose</a> per 40 grams (the size of a standard chocolate bar). So two chocolate bars (or the equivalent in milk chocolate eggs or bunnies) may be enough to cause symptoms. It’s worth noting that lactase enzyme activity dramatically declines as we age, with the highest activity in newborns and children. So lactose sensitivity or intolerance may not be such an issue for your kids and your symptoms may increase over time. Genetics also plays a major role in how sensitive people are to lactose. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6815241/">Allergic reactions</a> to chocolate are usually due to the added ingredients or cross-contamination with potential allergens such as nuts, milk, soy, and some sweeteners used in the production of chocolate. Symptoms can be mild (acne, rashes and stomach pain) or more severe (swelling of the throat and tongue and shortness of breath). If you or your family members have known allergic reactions, make sure you read the label before indulging – especially in a whole block or basket of the stuff. And if you or your family members do experience symptoms of an allergic reaction after eating chocolate, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/allergic-reactions-emergency-first-aid">seek medical attention</a> immediately. <h2>4 take home tips</h2> So, if you are like me and have a weakness for chocolate there are a few things you can do to make the experience a good one.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/202848/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <ol> <li>keep an eye out for the darker chocolate varieties with higher cocoa solids. You may notice a percentage on labelling, which refers to how much of its weight is from cocoa beans. In general, the higher this percentage, the lower the sugar. White chocolate has almost no cocoa solid, and mostly cocoa butter, sugar and other ingredients. Dark chocolate has 50–100% cocoa beans, and less sugar. Aim for at least 70% cocoa</li> <li>read the fine print for additives and possible cross-contamination, especially if allergies might be an issue</li> <li>the ingredients list and nutrition information panel should tell you all about the chocolate you choosing. Go for varieties with lower sugar and less saturated fat.

Does intermittent fasting have benefits for our brain?

<a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Intermittent fasting has become a popular dietary approach to help people lose or manage their <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8683964/">weight</a>. It has also been promoted as a way to reset metabolism, control chronic disease, slow ageing and <a href="https://pubmed.ncbi.nlm.nih.gov/27810402">improve overall health</a>. Meanwhile, some research suggests intermittent fasting may offer a different way for the brain to access energy and provide protection against neurodegenerative diseases like <a href="https://link.springer.com/article/10.1007/s11011-023-01288-2">Alzheimer’s disease</a>. This is not a new idea – the ancient Greeks believed fasting <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8839325/">enhanced thinking</a>. But what does the modern-day evidence say? <h2>First, what is intermittent fasting?</h2> Our <a href="https://pubmed.ncbi.nlm.nih.gov/35487190/">diets</a> – including calories consumed, macronutrient composition (the ratios of fats, protein and carbohydrates we eat) and when meals are consumed – are factors in our lifestyle we can change. People do this for cultural reasons, desired weight loss or potential health gains. Intermittent fasting consists of short periods of calorie (energy) restriction where food intake is limited for 12 to 48 hours (usually 12 to 16 hours per day), followed by periods of normal food intake. The intermittent component means a re-occurrence of the pattern rather than a “one off” fast. Food deprivation beyond 24 hours typically constitutes starvation. This is distinct from fasting due to its specific and potentially harmful biochemical alterations and nutrient deficiencies if continued for long periods. <h2>4 ways fasting works and how it might affect the brain</h2> The brain accounts for about <a href="https://theconversation.com/how-much-energy-do-we-expend-thinking-and-using-our-brain-197990">20% of the body’s energy consumption</a>. Here are four ways intermittent fasting can act on the body which could help explain its potential effects on the brain. 1. Ketosis The goal of many intermittent fasting routines is to flip a “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5913738/">metabolic switch</a>” to go from burning predominately carbohydrates to burning fat. This is called ketosis and typically occurs after 12–16 hours of fasting, when liver and glycogen stores are depleted. <a href="https://www.ncbi.nlm.nih.gov/books/NBK493179/">Ketones</a> – chemicals produced by this metabolic process – become the preferred energy source for the brain. Due to this being a slower metabolic process to produce energy and potential for lowering blood sugar levels, ketosis can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10844723/">cause symptoms</a> of hunger, fatigue, nausea, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8754590/">low mood</a>, irritability, constipation, headaches, and brain “fog”. At the same time, as glucose metabolism in the brain declines with ageing, studies have shown ketones could provide an alternative energy source to <a href="https://www.science.org/doi/10.1126/science.aau2095">preserve brain function</a> and prevent <a href="https://pubmed.ncbi.nlm.nih.gov/32709961/">age-related neurodegeneration disorders and cognitive decline</a>. Consistent with this, increasing ketones through <a href="https://pubmed.ncbi.nlm.nih.gov/31027873/">supplementation</a> or <a href="https://pubmed.ncbi.nlm.nih.gov/31757576/">diet</a> has been shown to improve cognition in adults with mild cognitive decline and those at risk of Alzheimer’s disease respectively. 2. Circadian syncing Eating at times that <a href="https://pubmed.ncbi.nlm.nih.gov/32480126/">don’t match our body’s natural daily rhythms</a> can disrupt how our organs work. Studies in shift workers have suggested this might also make us more prone to <a href="https://pubmed.ncbi.nlm.nih.gov/22010477/">chronic disease</a>. Time-restricted eating is when you eat your meals within a six to ten-hour window during the day when you’re most active. Time-restricted eating causes changes in <a href="https://pubmed.ncbi.nlm.nih.gov/36599299/">expression of genes in tissue</a> and helps the body during rest and activity. A 2021 <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7827225/">study of 883 adults</a> in Italy indicated those who restricted their food intake to ten hours a day were less likely to have cognitive impairment compared to those eating without time restrictions. 3. Mitochondria Intermittent fasting may provide <a href="https://pubmed.ncbi.nlm.nih.gov/35218914/">brain protection</a> through improving mitochondrial function, metabolism and reducing oxidants. Mitochondria’s <a href="https://www.genome.gov/genetics-glossary/Mitochondria">main role is to produce energy</a> and they are crucial to brain health. Many age-related diseases are closely related to an energy supply and demand imbalance, likely attributed to <a href="https://www.nature.com/articles/s41574-021-00626-7">mitochondrial dysfunction during ageing</a>. Rodent studies suggest alternate day fasting or reducing calories <a href="https://journals.sagepub.com/doi/10.1038/jcbfm.2014.114">by up to 40%</a> might protect or improve <a href="http://www.ncbi.nlm.nih.gov/pubmed/21861096">brain mitochondrial function</a>. But not all studies support this theory. 4. The gut-brain axis The <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6469458/">gut and the brain communicate with each other</a> via the body’s nervous systems. The brain can influence how the gut feels (think about how you get “butterflies” in your tummy when nervous) and the gut can affect mood, cognition and mental health. In mice, intermittent fasting has shown promise for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5913738/">improving brain health</a> by increasing survival and <a href="https://pubmed.ncbi.nlm.nih.gov/12354284/">formation of neurons</a> (nerve cells) in the hippocampus brain region, which is involved in memory, learning and emotion. There’s <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8470960/">no clear evidence</a> on the effects of intermittent fasting on cognition in healthy adults. However one 2022 study interviewed 411 older adults and found <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9646955/">lower meal frequency</a> (less than three meals a day) was associated with reduced evidence of Alzheimer’s disease on brain imaging. Some research has suggested calorie restriction may have a protective effect against <a href="https://academic.oup.com/nutritionreviews/article/81/9/1225/7116310">Alzheimer’s disease</a> by reducing oxidative stress and inflammation and promoting vascular health. When we look at the effects of overall energy restriction (rather than intermittent fasting specifically) the evidence is mixed. Among people with mild cognitive impairment, one study showed <a href="https://pubmed.ncbi.nlm.nih.gov/26713821/">cognitive improvement</a> when participants followed a calorie restricted diet for 12 months. Another study found a 25% calorie restriction was associated with <a href="https://pubmed.ncbi.nlm.nih.gov/30968820">slightly improved working memory</a> in healthy adults. But a <a href="https://www.sciencedirect.com/science/article/pii/S0022316623025221?via%3Dihub">recent study</a>, which looked at the impact of calorie restriction on spatial working memory, found no significant effect. <h2>Bottom line</h2> Studies in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9740746/">mice</a> support a role for intermittent fasting in improving brain health and ageing, but few studies in humans exist, and the evidence we have is mixed. Rapid weight loss associated with calorie restriction and intermittent fasting can lead to nutrient deficiencies, muscle loss, and decreased immune function, particularly in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8749464/">older adults</a> whose nutritional needs may be higher. Further, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6314618/">prolonged fasting</a> or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9042193/">severe calorie restriction</a> may pose risks such as fatigue, dizziness, and electrolyte imbalances, which could exacerbate existing health conditions. If you’re considering <a href="https://www.nejm.org/doi/10.1056/NEJMra1905136?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">intermittent fasting</a>, it’s best to seek advice from a health professional such as a dietitian who can provide guidance on structuring fasting periods, meal timing, and nutrient intake. This ensures intermittent fasting is approached in a safe, sustainable way, tailored to individual needs and goals.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/223181/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, Assistant Professor, Faculty of Health Sciences and Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mothers’ dieting habits and self-talk have profound impact on daughters − 2 psychologists explain how to cultivate healthy behaviors and body image

<a href="https://theconversation.com/profiles/janet-j-boseovski-451496">Janet J. Boseovski</a>, <a href="https://theconversation.com/institutions/university-of-north-carolina-greensboro-2069">University of North Carolina – Greensboro</a> and <a href="https://theconversation.com/profiles/ashleigh-gallagher-1505989">Ashleigh Gallagher</a>, <a href="https://theconversation.com/institutions/university-of-north-carolina-greensboro-2069">University of North Carolina – Greensboro</a> Weight loss is one of the most common health and appearance-related goals. Women and <a href="https://www.cdc.gov/nchs/products/databriefs/db340.htm">teen girls</a> are <a href="https://www.cdc.gov/nchs/products/databriefs/db313.htm">especially likely to pursue dieting</a> to achieve weight loss goals even though a great deal of research shows that <a href="https://theconversation.com/what-thin-people-dont-understand-about-dieting-86604">dieting doesn’t work over the long term</a>. We are a <a href="https://www.duck-lab.com/people">developmental psychologist</a> and a <a href="https://psy.uncg.edu/directory/ashleigh-gallagher/">social psychologist</a> who together wrote a forthcoming book, “Beyond Body Positive: A Mother’s Evidence-Based Guide for Helping Girls Build a Healthy Body Image.” In the book, we address topics such as the effects of maternal dieting behaviors on daughters’ health and well-being. We provide information on how to build a foundation for healthy body image beginning in girlhood. <h2>Culturally defined body ideals</h2> Given the strong influence of social media and other cultural influences on body ideals, it’s understandable that so many people pursue diets aimed at weight loss. <a href="https://communityhealth.mayoclinic.org/featured-stories/tiktok-diets">TikTok</a>, YouTube, Instagram and celebrity websites feature slim influencers and “how-tos” for achieving those same results in no time. For example, women and teens are engaging in rigid and extreme forms of exercise such as 54D, a program to <a href="https://54d.com/">achieve body transformation in 54 days</a>, or the <a href="https://health.clevelandclinic.org/75-hard-challenge-and-rules">75 Hard Challenge</a>, which is to follow five strict rules for 75 days. For teens, these pursuits are likely fueled by trendy body preoccupations such as the desire for “<a href="https://www.nytimes.com/2024/02/06/well/move/tiktok-legging-legs-eating-disorders.html">legging legs</a>.” Women and teens have also been been inundated with recent messaging around <a href="https://theconversation.com/drugs-that-melt-away-pounds-still-present-more-questions-than-answers-but-ozempic-wegovy-and-mounjaro-could-be-key-tools-in-reducing-the-obesity-epidemic-205549">quick-fix weight loss drugs</a>, which come with a lot of caveats. Dieting and weight loss goals are highly individual, and when people are intensely self-focused, it is <a href="https://doi.org/10.1521/jscp.2000.19.1.70">possible to lose sight of the bigger picture</a>. Although women might wonder what the harm is in trying the latest diet, science shows that dieting behavior doesn’t just affect the dieter. In particular, for women who are mothers or who have other girls in their lives, these behaviors affect girls’ emerging body image and their health and well-being. <h2>The profound effect of maternal role models</h2> Research shows that mothers and maternal figures <a href="https://doi.org/10.1016/j.brat.2017.11.001">have a profound influence on their daughters’ body image</a>. The opportunity to influence girls’ body image comes far earlier than adolescence. In fact, research shows that these influences on body image <a href="https://www.teenvogue.com/story/how-toxic-diet-culture-is-passed-from-moms-to-daughters">begin very early in life</a> – <a href="https://doi.org/10.1016/bs.acdb.2016.10.006">during the preschool years</a>. Mothers may feel that they are being discreet about their dieting behavior, but little girls are watching and listening, and they are far more observant of us than many might think. For example, one study revealed that compared with daughters of nondieting women, 5-year-old girls whose mothers dieted <a href="https://doi.org/10.1016/S0002-8223(00)00339-4">were aware of the connection between dieting and thinness</a>. Mothers’ eating behavior does not just affect girls’ ideas about dieting, but also their daughters’ eating behavior. The amount of food that mothers eat <a href="https://doi.org/10.1016/j.appet.2018.04.018">predicts how much their daughters will eat</a>. In addition, daughters whose mothers are dieters are <a href="https://doi.org/10.1016/j.appet.2018.04.018">more likely to become dieters themselves</a> and are also <a href="https://doi.org/10.1016/j.eatbeh.2007.03.001">more likely to have a negative body image</a>. Negative body image is <a href="https://theconversation.com/mounting-research-documents-the-harmful-effects-of-social-media-use-on-mental-health-including-body-image-and-development-of-eating-disorders-206170">not a trivial matter</a>. It affects girls’ and women’s mental and physical well-being in a <a href="https://doi.org/10.1177/1359105317710815">host of ways</a> and <a href="https://doi.org/10.1016/j.brat.2011.06.009">can predict the emergence of eating disorders</a>. <h2>Avoiding ‘fat talk’</h2> What can moms do, then, to serve their daughters’ and their own health? They can focus on small steps. And although it is best to begin these efforts early in life – in girlhood – it is never too late to do so. For example, mothers can consider how they think about and talk about themselves around their daughters. Engaging in “fat talk” may inadvertently send their daughters the message that larger bodies are bad, <a href="https://doi.org/10.1016/j.bodyim.2020.07.004">contributing to weight bias</a> and negative self-image. Mothers’ fat talk also <a href="https://doi.org/10.1080/15267431.2021.1908294">predicts later body dissatisfaction in daughters</a>. And negative self-talk isn’t good for mothers, either; it is associated with <a href="https://doi.org/10.1177/1359105318781943">lower motivation and unhealthful eating</a>. Mothers can instead practice and model self-compassion, which involves treating oneself the way <a href="https://doi.org/10.1016/j.bodyim.2016.03.003">a loving friend might treat you</a>. In discussions about food and eating behavior, it is important to avoid moralizing certain kinds of food by labeling them as “good” or “bad,” as girls may extend these labels to their personal worth. For example, a young girl may feel that she is being “bad” if she eats dessert, if that is what she has learned from observing the women around her. In contrast, she may feel that she has to eat a salad to be “good.” Moms and other female role models can make sure that the dinner plate sends a healthy message to their daughters by showing instead that all foods can fit into a balanced diet when the time is right. Intuitive eating, which emphasizes paying attention to hunger and satiety and allows flexibility in eating behavior, is associated with <a href="https://doi.org/10.1007/s40519-020-00852-4">better physical and mental health in adolescence</a>. Another way that women and especially moms can buffer girls’ body image is by helping their daughters <a href="https://doi.org/10.1016/j.bodyim.2021.12.009">to develop media literacy</a> and to think critically about the nature and purpose of media. For example, moms can discuss the misrepresentation and distortion of bodies, such as the use of filters to enhance physical appearance, on social media. <h2>Focusing on healthful behaviors</h2> One way to begin to focus on health behaviors rather than dieting behaviors is to develop respect for the body and to <a href="https://theconversation.com/body-neutrality-what-it-is-and-how-it-can-help-lead-to-more-positive-body-image-191799">consider body neutrality</a>. In other words, prize body function rather than appearance and spend less time thinking about your body’s appearance. Accept that there are times when you may not feel great about your body, and that this is OK. To feel and look their best, mothers can aim to stick to a <a href="https://theconversation.com/whats-the-best-diet-for-healthy-sleep-a-nutritional-epidemiologist-explains-what-food-choices-will-help-you-get-more-restful-zs-219955">healthy sleep schedule</a>, manage their stress levels, <a href="https://theconversation.com/fiber-is-your-bodys-natural-guide-to-weight-management-rather-than-cutting-carbs-out-of-your-diet-eat-them-in-their-original-fiber-packaging-instead-205159">eat a varied diet</a> that includes all of the foods that they enjoy, and <a href="https://theconversation.com/the-runners-high-may-result-from-molecules-called-cannabinoids-the-bodys-own-version-of-thc-and-cbd-170796">move and exercise their bodies regularly</a> as lifelong practices, rather than engaging in quick-fix trends. Although many of these tips sound familiar, and perhaps even simple, they become effective when we recognize their importance and begin acting on them. Mothers can work toward modeling these behaviors and tailor each of them to their daughter’s developmental level. It’s never too early to start. <h2>Promoting healthy body image</h2> Science shows that several personal characteristics are associated with body image concerns among women. For example, research shows that women who are <a href="https://doi.org/10.1016/j.bodyim.2020.02.001">higher in neuroticism</a> <a href="https://doi.org/10.1186/2050-2974-1-2">and perfectionism</a>, <a href="https://doi.org/10.3389/fpsyg.2022.983534">lower in self-compassion</a> or <a href="https://doi.org/10.1016/j.bodyim.2013.08.001">lower in self-efficacy</a> are all more likely to struggle with negative body image. Personality is frequently defined as a person’s characteristic pattern of thoughts, feelings and behaviors. But if they wish, <a href="https://doi.org/10.1002/per.1945">mothers can change personality characteristics</a> that they feel aren’t serving them well. For example, perfectionist tendencies – such as setting unrealistic, inflexible goals – can be examined, challenged and replaced with more rational thoughts and behaviors. A woman who believes she must work out every day can practice being more flexible in her thinking. One who thinks of dessert as “cheating” can practice resisting moral judgments about food. Changing habitual ways of thinking, feeling and behaving certainly takes effort and time, but it is far more likely than diet trends to bring about sustainable, long-term change. And taking the first steps to modify even a few of these habits can positively affect daughters. In spite of all the noise from media and other cultural influences, mothers can feel empowered knowing that they have a significant influence on their daughters’ feelings about, and treatment of, their bodies. In this way, mothers’ modeling of healthier attitudes and behaviors is a sound investment – for both their own body image and that of the girls they love.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221968/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/janet-j-boseovski-451496">Janet J.

The best diet for 2024

Over years of research and diet rankings, there is one regimen that scientists have crowned the "Best Diet Overall" for seven years in a row. The Mediterranean diet has topped the list in <a href="https://health.usnews.com/best-diet/best-diets-overall" target="_blank" rel="noopener">US News and World Reports’</a> annual ranking for 2024, followed by the DASH diet, and the MIND diet coming in third. The ranking is based off the findings of a panel of leading medical and nutrition experts, who analyse the nutritional completeness, health risks and benefits, long-term sustainability and effectiveness of the diet in addressing its goals. What sets it apart from other diets? The Mediterranean diet emphasises multiple servings of fruits and vegetables daily, alongside whole grains, legumes, nuts, olive oil and seafood. Red meats, dairy and poultry are consumed occasionally and in moderation, and highly processed foods and added sugars are generally avoided. <h4>What are its benefits?</h4> The experts found that following the diet long term can increase the odds of living a longer, healthier life, with a few other studies suggesting it lowers the risk of heart disease and Type 2 diabetes, while potentially slowing cognitive decline. “It’s a way of life, it’s a cuisine, it dates back thousands of years, and in the last five to six decades, it is the most highly researched cuisine in the world,” said Dr Catherine Itsiopoulos, a professor of nutrition and dietetics at RMIT University in Melbourne. Lowers risk of heart disease A 2021 research review found that the diet has been shown to reduce the risk of coronary heart disease in women by 29 per cent and stroke by 13 per cent. A 2017 analysis found that on average it lowers the risk of coronary heart disease, heart attacks and strokes by 40 per cent. Experts suggest that this may be because the fats in olive oil, seeds, fish and nuts are monounsaturated or polyunsaturated fats aka healthy fats. Additionally, because of its emphasis on fruits, vegetables and legumes, which contain antioxidants and other beneficial compounds, it is believed to combat chronic inflammation. Lowers chances of developing type 2 diabetes Because this diet relies heavily on honey and cinnamon as sweeteners, and fruits as a primary source of sugar, it reduces the risk of developing this disease. One study conducted on 300,000 participants found that those who were on the Mediterranean diet had a nearly 30 per cent lower risk of Type 2 diabetes. Good for your gut The diet contains a lot of fibre which are associated with more regular bowel movements, lower blood pressure, cholesterol and blood sugar levels, according to the Food and Drug Administration. This is because good bacteria in our stomachs feed off fibre, which creates a stronger lining in the intestines. There are a few other potential health benefits including reducing risk of dementia among seniors by almost 25 per cent, and lowering the risk of death from cancer including breast, colorectal, head and neck and lung cancers.

How dieting, weight suppression and even misuse of drugs like Ozempic can contribute to eating disorders

<a href="https://theconversation.com/profiles/samantha-withnell-1504436">Samantha Withnell</a>, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> and <a href="https://theconversation.com/profiles/lindsay-bodell-1504260">Lindsay Bodell</a>, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> Up to 72 per cent of women and 61 per cent of men are dissatisfied with their weight or <a href="https://doi.org/10.1016/j.eatbeh.2014.04.010">body image</a>, according to a U.S. study. Globally, millions of people <a href="https://doi.org/10.1111%2Fobr.12466">attempt to lose weight</a> every year with the hope that weight loss will have positive effects on their body image, health and quality of life. However, these motivated individuals often struggle to maintain new diets or exercise regimens. The rise of medications such as semaglutides, like <a href="https://dhpp.hpfb-dgpsa.ca/dhpp/resource/101298">Ozempic</a> or <a href="https://dhpp.hpfb-dgpsa.ca/dhpp/resource/101765">Wegovy</a>, <a href="https://www.cbc.ca/news/health/ozempic-weight-loss-1.6772021">might be viewed as an appealing “quick fix”</a> alternative to meet weight loss goals. Research led by our team and others suggests that such attempts to lose weight often do more harm than good, and even increase the risk of <a href="https://osf.io/9stq2">developing an eating disorder</a>. <h2>Weight loss and eating disorders</h2> Eating disorders are <a href="https://doi.org/10.1002/eat.20589">serious mental health conditions</a> primarily characterized by extreme patterns of under- or over-eating, concerns about one’s shape or body weight or other behaviours intended to influence body shape or weight such as exercising excessively or self-inducing vomiting. Although once thought to only affect young, white adolescent girls, eating disorders do not discriminate; eating disorders can develop in people of <a href="https://doi.org/10.1002/erv.2553">any age, sex, gender or racial/ethnic background</a>, with an estimated <a href="https://nedic.ca/general-information/">one million Canadians</a> suffering from an eating disorder at any given time. Feb. 1 to 7 is <a href="https://nedic.ca/edaw/">National Eating Disorders Awareness Week</a>. As a clinical psychologist and clinical psychology graduate student, our research has focused on how eating disorders develop and what keeps them going. Pertinent to society’s focus on weight-related goals, our research has examined associations between weight loss and eating disorder symptoms. <h2>Eating disorders and ‘weight suppression’</h2> In eating disorders research, the state of maintaining weight loss is referred to as “weight suppression.” Weight suppression is typically defined as the difference between a person’s current weight and their highest lifetime weight (excluding pregnancy). Despite the belief that weight loss will improve body satisfaction, we found that in a sample of over 600 men and women, weight loss had no impact on women’s negative body image and was associated with increased body dissatisfaction in <a href="https://doi.org/10.1016/j.bodyim.2023.01.011">men</a>. Importantly, being more weight suppressed has been associated with the <a href="https://doi.org/10.1093/ajcn/nqaa146">onset of eating disorders</a>, including anorexia nervosa and bulimia nervosa. <a href="https://doi.org/10.1007/s11920-018-0955-2">One proposed explanation</a> for the relationship between weight suppression and eating disorders is that maintaining weight loss becomes increasingly difficult as body systems that <a href="https://doi.org/10.3945/ajcn.110.010025">reduce metabolic rate and energy expenditure, and increase appetite</a>, are activated to promote weight gain. There is growing awareness that <a href="https://doi.org/10.1136/bmj.g2646">weight regain is highly likely following conventional diet programs</a>. This might lead people to engage in more and more extreme behaviours to control their weight, or they might shift between extreme restriction of food intake and episodes of overeating or binge eating, the characteristic symptoms of bulimia nervosa. <h2>Ozempic and other semaglutide drugs</h2> Semaglutide drugs like Ozempic and Wegovy are part of a class of drug called <a href="https://pdf.hres.ca/dpd_pm/00067924.PDF">glucagon-like peptide-1 agonists (GLP-1As)</a>. These drugs work by mimicking the hormone GLP-1 to interact with neural pathways that signal satiety (fullness) and slow stomach emptying, leading to reduced food intake. Although GLP-1As are indicated to treat Type 2 diabetes, <a href="https://www.cbc.ca/news/canada/london/ozempic-off-label-1.6884141">they are increasingly prescribed off-label</a> or being <a href="https://www.bbc.com/news/health-67414203">illegally purchased</a> without a prescription because of their observed effectiveness at inducing weight loss. Although medications like Ozempic do often lead to weight loss, the rate of weight loss may <a href="https://doi.org/10.1001/jama.2021.3224">slow down or stop over time</a>. Research by Lindsay Bodell, one of the authors of this story, and her colleagues on weight suppression may help explain why effects of semaglutides diminish over time, as <a href="https://doi.org/10.1016/j.physbeh.2019.112565">weight suppression is associated with reduced GLP-1 response</a>. This means those suppressing their weight could become less responsive to the satiety signals activated by GLP-1As. Additionally, weight loss effects are only seen for as long as the medication is taken, meaning those who take these drugs to achieve some weight loss goal are <a href="https://doi.org/10.1111/dom.14725">likely to regain most, if not all, weight lost</a> when they stop taking the medication. <h2>Risks of dieting and weight-loss drugs</h2> The growing market for off-label weight loss drugs is concerning, because of the exacerbation of <a href="https://theconversation.com/ozempic-the-miracle-drug-and-the-harmful-idea-of-a-future-without-fat-211661">weight stigma</a> and the serious <a href="https://doi.org/10.1016/j.jand.2022.01.004">health risks</a> associated with unsupervised weight loss, including developing eating disorders. Researchers and health professionals are already raising the alarm about the use of GLP-1As in children and adolescents, due to concerns about their possible <a href="https://doi.org/10.1017/cts.2023.612">impact on growth and development</a>. Moreover, popular weight-loss methods, whether they involve pills or “crash diets,” often mimic symptoms of eating disorders. For example, intermittent fasting diets that involve long periods of fasting followed by short periods of food consumption may mimic and <a href="https://doi.org/10.1016/j.eatbeh.2022.101681">increase the risk of developing binge eating problems</a>. The use of diet pills or laxatives to lose weight has been found to increase the risk of <a href="https://doi.org/10.2105/AJPH.2019.305390">being diagnosed with an eating disorder in the next one to three years</a>. Drugs like Ozempic may also be <a href="https://doi.org/10.1002/eat.24109">misused by individuals already struggling with an eating disorder</a> to suppress their appetite, compensate for binge eating episodes or manage fear of weight gain. Individuals who are already showing signs of an eating disorder, such as limiting their food intake and intense concerns about their weight, may be most at risk of spiralling from a weight loss diet or medication into an eating disorder, <a href="https://doi.org/10.1002/eat.24116">even if they only lose a moderate amount of weight</a>. People who are dissatisfied with their weight or have made multiple attempts to lose weight often feel pressured to try increasingly drastic methods. However, any diet, exercise program or weight-loss medication promising a quick fix for weight loss should be treated with extreme caution. At best, you may gain the weight back; at worst, you put yourself at risk for much more serious eating disorders and other health problems.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221514/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/samantha-withnell-1504436">Samantha Withnell</a>, PhD Candidate, Clinical Psychology, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> and <a href="https://theconversation.com/profiles/lindsay-bodell-1504260">Lindsay Bodell</a>, Assistant Professor of Psychology, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
