Woman cured of Type 1 diabetes in life-changing clinical trial

<p>Marlaina Goedel was diagnosed with Type 1 diabetes when she was just five-years-old, and not only was the disease controlling her, but it almost cost her life. </p> <p>"I've crashed my car into a brick building before having a diabetic attack while driving," Goedel recalled. </p> <p>Her condition was so extreme that she felt robbed of a normal childhood, telling the <em>Daily Mail </em>that she was in and out of hospital with  life-threatening diabetic ketoacidosis, which causes toxic chemicals to build up in the blood due to a lack of insulin.</p> <p>Now 30-years-old, the Illinois woman no longer needs daily insulin shots and can finally enjoy sugar again thanks to a pioneering stem cell therapy that has cured her of type 1 diabetes. </p> <p>Goedel was one of three Americans who have been cured of their type 1 diabetes thanks to the clinical trial involving an islet cell transplant. </p> <p>It is a one-off infusion that involved transplanting islet cells into her liver to help her body produce insulin on its own. </p> <p>After four weeks, she no longer needed to take insulin. </p> <p>"[My doctor] said, ‘Mark it on your calendar. Today is the day. Stop all insulin,'" Goedel said of the life-changing moment. </p> <p>"I just went quiet and finally said, ‘I’m here. I’m in shock. I’m going to need you to repeat that.’"</p> <p>The trial was being run at the University of Chicago Medicine Transplant Institute. </p> <p>While Islet cell transplants isn't a new procedure, the current anti-rejection medication used can be toxic to the transplanted cells, potentially making it less effective over time. </p> <p>The clinical trial that ran at the university tested out a new antibody called tegoprubart, which was given to Goedel and the two other patients. </p> <p>Tegoprubart is made from lab-made antibodies that trick the immune system into thinking the body made the cells on its own, preventing them from being rejected. </p> <p>The patients were then given islet cells from a deceased donor's pancreas, which were then infused into the patient's small blood vessels in their liver. Those cells then lodged into the blood vessels and started producing insulin. </p> <p>For Goedel the only side effect of the procedure was "feeling like I got punched in the ribs,"  with the procedure lasting just an hour. </p> <p>"The cure is out there," Goedel told the <em>Daily Mail. </em></p> <p>With her new lease on life, Goedel plans to go back to school and go horse riding without worrying about suffering an attack and causing an accident. </p> <p>"It took a while to get used to saying, 'I am cured. I am diabetes free.' It's been very freeing," she said.</p> <p>"No one should have to live with this disease. I know that now more than ever."</p> <p><em>Images: Good Morning America/ UChicago Medicine</em></p> <p> </p>

For type 2 diabetes, focusing on when you eat – not what – can help control blood sugar

<p><em><a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Type 2 diabetes affects <a href="https://www.aihw.gov.au/reports/diabetes/diabetes/contents/how-common-is-diabetes/type-2-diabetes">1.2 million Australians</a> and accounts for <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">85-90%</a> of all diabetes cases. This chronic condition is characterised by high blood glucose (sugar) levels, which carry serious <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(17)30058-2/abstract">health</a> risks. <a href="https://www.nature.com/articles/nrendo.2017.151">Complications</a> include heart disease, kidney failure and vision problems.</p> <p>Diet is an important way people living with type 2 diabetes manage blood glucose, alongside exercise and medication. But while we know individualised, professional dietary advice improves blood glucose, it can be <a href="https://linkinghub.elsevier.com/retrieve/pii/S0168822717317588">complex</a> and is not always <a href="https://www.publish.csiro.au/py/PY13021">accessible</a>.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">Our new study</a> looked at the impact of time-restricted eating – focusing on when you eat, rather than what or how much – on blood glucose levels.</p> <p>We found it had similar results to individualised advice from an accredited practising dietitian. But there were added benefits, because it was simple, achievable, easy to stick to – and motivated people to make other positive changes.</p> <h2>What is time-restricted eating?</h2> <p>Time-restricted eating, also known as <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-nutr-082018-124320">the 16:8 diet</a>, became popular for weight loss around 2015. Studies have since shown it is also an <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2811116">effective way</a> for people with type 2 diabetes to manage blood glucose.</p> <p>Time-restricted eating involves limiting when you eat each day, rather than focusing on what you eat. You restrict eating to a window during daylight hours, for example between 11am and 7pm, and then fast for the remaining hours. This can sometimes naturally lead to also eating less.</p> <p>Giving your body a break from constantly digesting food in this way helps align eating with natural <a href="https://doi.org/10.1111/jne.12886">circadian rhythms</a>. This <a href="https://doi.org/10.1111/jnc.15246">can help</a> regulate metabolism and improve overall health.</p> <p>For people with type 2 diabetes, there may be specific benefits. They often have their <a href="https://doi.org/10.2337/dc12-2127">highest blood glucose</a> reading in the morning. Delaying breakfast to mid-morning means there is time for physical activity to occur to help reduce glucose levels and prepare the body for the first meal.</p> <h2>How we got here</h2> <p>We ran an <a href="https://www.mdpi.com/2072-6643/12/11/3228">initial study</a> in 2018 to see whether following time-restricted eating was achievable for people with type 2 diabetes. We found participants could easily stick to this eating pattern over four weeks, for an average of five days a week.</p> <p>Importantly, they also had improvements in blood glucose, spending less time with high levels. <a href="https://www.mdpi.com/2072-6643/12/2/505">Our previous research</a> suggests the reduced time between meals may play a role in how the hormone insulin is able to reduce glucose concentrations.</p> <p><a href="https://doi.org/10.1001/jamanetworkopen.2023.39337">Other studies</a> have confirmed these findings, which have <a href="https://doi.org/10.1186/s12986-021-00613-9">also shown</a> notable improvements in HbA1c. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK304271/">marker</a> in the blood that represents concentrations of blood glucose over an average of three months. It is the <a href="https://journals.sagepub.com/doi/10.4137/BMI.S38440">primary clinical tool</a> used for diabetes.</p> <p>However, these studies provided intensive support to participants through weekly or fortnightly meetings with researchers.</p> <p>While we know this level of support <a href="https://www.nature.com/articles/0802295">increases</a> how likely people are to stick to the plan and improves outcomes, it is not readily available to everyday Australians living with type 2 diabetes.</p> <h2>What we did</h2> <p>In our <a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">new study</a>, we compared time-restricted eating directly with advice from an <a href="https://dietitiansaustralia.org.au/working-dietetics/standards-and-scope/role-accredited-practising-dietitian">accredited practising dietitian</a>, to test whether results were similar across six months.</p> <p>We recruited 52 people with type 2 diabetes who were currently managing their diabetes with up to two oral medications. There were 22 women and 30 men, aged between 35 and 65.</p> <p>Participants were randomly divided into two groups: diet and time-restricted eating. In both groups, participants received four consultations across the first four months. During the next two months they managed diet alone, without consultation, and we continued to measure the impact on blood glucose.</p> <p>In the diet group, consultations focused on changing their diet to control blood glucose, including improving diet quality (for example, eating more vegetables and limiting alcohol).</p> <p>In the time-restricted eating group, advice focused on how to limit eating to a nine-hour window between 10am and 7pm.</p> <p>Over six months, we measured each participant’s blood glucose levels every two months using the HbA1c test. Each fortnight, we also asked participants about their experience of making dietary changes (to what or when they ate).</p> <h2>What we found</h2> <p>We found time-restricted eating was as effective as the diet intervention.</p> <p>Both groups had reduced blood glucose levels, with the greatest improvements occurring after the first two months. Although it wasn’t an objective of the study, some participants in each group also lost weight (5-10kg).</p> <p>When surveyed, participants in the time-restricted eating group said they had adjusted well and were able to follow the restricted eating window. Many told us they had family support and enjoyed earlier mealtimes together. Some also found they slept better.</p> <p>After two months, people in the time-restricted group were looking for more dietary advice to further improve their health.</p> <p>Those in the diet group were less likely to stick to their plan. Despite similar health outcomes, time-restricted eating seems to be a simpler initial approach than making complex dietary changes.</p> <h2>Is time-restricted eating achievable?</h2> <p>The main barriers to following time-restricted eating are social occasions, caring for others and work schedules. These factors may prevent people eating within the window.</p> <p>However, there are many benefits. The message is simple, focusing on when to eat as the main diet change. This may make time-restricted eating more translatable to people from a wider variety of socio-cultural backgrounds, as the types of foods they eat don’t need to change, just the timing.</p> <p>Many people don’t have access to more individualised support from a dietitian, and receive nutrition advice from their GP. This makes time-restricted eating an alternative – and equally effective – strategy for people with type 2 diabetes.</p> <p>People should still try to stick to <a href="https://www.eatforhealth.gov.au/guidelines/guidelines">dietary guidelines</a> and prioritise vegetables, fruit, wholegrains, lean meat and healthy fats.</p> <p>But our study showed time-restricted eating may also serve as stepping stone for people with type 2 diabetes to take control of their health, as people became more interested in making diet and other positive changes.</p> <p>Time-restricted eating might not be appropriate for everyone, especially people on medications which don’t recommend fasting. Before trying this dietary change, it’s best speak to the healthcare professional who helps you manage diabetes.<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/241472/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, Research Fellow in Exercise Metabolism and Nutrition, Mary MacKillop Institute for Health Research, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, Lecturer in Nutrition and Dietetics, School of Human Movement and Nutrition Sciences, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is type 1.5 diabetes? It’s a bit like type 1 and a bit like type 2 – but it’s often misdiagnosed

<p><em><a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> and <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>While you’re likely familiar with type 1 and type 2 diabetes, you’ve probably heard less about type 1.5 diabetes.</p> <p>Also known as latent autoimmune diabetes in adults (LADA), type 1.5 diabetes has features of <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">both type 1 and type 2 diabetes</a>.</p> <p>More people became aware of this condition after <a href="https://www.imdb.com/name/nm0004726/">Lance Bass</a>, best known for his role in the iconic American pop band NSYNC, <a href="https://www.foxnews.com/health/pop-singer-lance-bass-type-1-5-diabetes-know-disease">recently revealed</a> he has it.</p> <p>So, what is type 1.5 diabetes? And how is it diagnosed and treated?</p> <h2>There are several types of diabetes</h2> <p>Diabetes mellitus is a group of conditions that arise when the levels of glucose (sugar) in our blood are higher than normal. There are actually <a href="https://diabetesjournals.org/care/article/37/Supplement_1/S81/37753/Diagnosis-and-Classification-of-Diabetes-Mellitus">more than ten types</a> of diabetes, but the <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)01301-6/fulltext">most common</a> are type 1 and type 2.</p> <p>Type 1 diabetes is an <a href="https://diabetesjournals.org/care/article/44/11/2589/138492/The-Management-of-Type-1-Diabetes-in-Adults-A">autoimmune condition</a> where the body’s immune system attacks and destroys the cells in the pancreas that make the hormone insulin. This leads to very little or no insulin production.</p> <p>Insulin is important for moving glucose from the blood into our cells to be used for energy, which is why people with type 1 diabetes need <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6995794/">insulin medication daily</a>. Type 1 diabetes usually <a href="https://www.nature.com/articles/s41390-024-03107-5">appears</a> in children or young adults.</p> <p>Type 2 diabetes is not an autoimmune condition. Rather, it happens when the body’s cells become resistant to insulin over time, and the pancreas is no longer able to make enough insulin to <a href="https://diabetesjournals.org/care/article/47/Supplement_1/S20/153954/2-Diagnosis-and-Classification-of-Diabetes">overcome this resistance</a>. Unlike type 1 diabetes, people with type 2 diabetes still produce some insulin.</p> <p>Type 2 is more common in adults but is <a href="https://www.sciencedirect.com/science/article/abs/pii/S1871402121002733">increasingly</a> seen in children and young people. Management <a href="https://www.racgp.org.au/getattachment/41fee8dc-7f97-4f87-9d90-b7af337af778/Management-of-type-2-diabetes-A-handbook-for-general-practice.aspx">can include</a> behavioural changes such as nutrition and physical activity, as well as oral medications and insulin therapy.</p> <h2>How does type 1.5 diabetes differ from types 1 and 2?</h2> <p>Like type 1 diabetes, type 1.5 occurs when the immune system attacks the pancreas cells that make insulin. But people with type 1.5 often don’t need insulin <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">immediately</a> because their condition develops more slowly. Most people with type 1.5 diabetes will need to use insulin within <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5111528/">five years</a> of diagnosis, while those with type 1 typically require it from diagnosis.</p> <p>Type 1.5 diabetes is usually diagnosed in people <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">over 30</a>, likely due to the slow progressing nature of the condition. This is older than the typical age for type 1 diabetes but younger than the usual diagnosis age for type 2.</p> <p>Type 1.5 diabetes shares <a href="https://www.nature.com/articles/nrendo.2017.99">genetic and autoimmune risk factors</a> with type 1 diabetes such as specific gene variants. However, evidence has also shown it may be influenced by lifestyle factors such as <a href="https://pubmed.ncbi.nlm.nih.gov/29589073/">obesity</a> and <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2019.00320/full">physical inactivity</a> which are more commonly associated with type 2 diabetes.</p> <h2>What are the symptoms, and how is it treated?</h2> <p>The symptoms of type 1.5 diabetes are highly variable between people. Some have no symptoms at all. But generally, people may experience the following <a href="https://www.ncbi.nlm.nih.gov/books/NBK557897/">symptoms</a>:</p> <ul> <li>increased thirst</li> <li>frequent urination</li> <li>fatigue</li> <li>blurred vision</li> <li>unintentional weight loss.</li> </ul> <p>Typically, type 1.5 diabetes is <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">initially treated</a> with oral medications to keep blood glucose levels in normal range. Depending on their glucose control and the medication they are using, people with type 1.5 diabetes may need to monitor their blood glucose levels regularly throughout the day.</p> <p>When average blood glucose levels increase beyond normal range even with oral medications, treatment may progress to insulin. However, there are <a href="https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2022.959011/full">no universally accepted</a> management or treatment strategies for type 1.5 diabetes.</p> <h2>Type 1.5 diabetes is often misdiagnosed</h2> <p>Lance Bass said he was initially diagnosed with <a href="https://www.healthline.com/health-news/lance-bass-misdiagnosed-diabetes">type 2 diabetes</a>, but later learned he actually has type 1.5 diabetes. This is <a href="https://journals.lww.com/jaanp/abstract/2009/03000/latent_autoimmune_diabetes_of_adulthood__lada___an.4.aspx">not entirely uncommon</a>. Estimates suggest type 1.5 diabetes is misdiagnosed as type 2 diabetes <a href="https://www.sciencedirect.com/science/article/abs/pii/S1043276018301292">5–10% of the time</a>.</p> <p>There are a few possible reasons for this.</p> <p>First, accurately diagnosing type 1.5 diabetes, and distinguishing it from other types of diabetes, requires special <a href="https://journals.lww.com/jaanp/abstract/2009/03000/latent_autoimmune_diabetes_of_adulthood__lada___an.4.aspx">antibody tests</a> (a type of blood test) to detect autoimmune markers. Not all health-care professionals necessarily order these tests routinely, either due to cost concerns or because they may not consider them.</p> <p>Second, type 1.5 diabetes is commonly found in adults, so doctors might wrongly assume a person has developed type 2 diabetes, which is more common in this age group (whereas type 1 diabetes usually affects children and young adults).</p> <p>Third, people with <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">type 1.5 diabetes</a> often initially make enough insulin in the body to manage their blood glucose levels without needing to start insulin medication. This can make their condition appear like type 2 diabetes, where people also produce some insulin.</p> <p>Finally, because type 1.5 diabetes has <a href="https://www.ncbi.nlm.nih.gov/books/NBK557897/">symptoms</a> that are similar to type 2 diabetes, it may initially be treated as type 2.</p> <h2>We’re still learning about type 1.5</h2> <p>Compared with type 1 and type 2 diabetes, there has been much less research on how common type 1.5 diabetes is, especially in <a href="https://www.sciencedirect.com/science/article/abs/pii/S1043276018301292">non-European populations</a>. In 2023, it was estimated type 1.5 diabetes represented <a href="https://pubmed.ncbi.nlm.nih.gov/37428296/">8.9%</a> of all diabetes cases, which is similar to type 1. However, we need more research to get accurate numbers.</p> <p>Overall, there has been a limited awareness of type 1.5 diabetes and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10683931/">unclear diagnostic criteria</a> which have slowed down our understanding of this condition.</p> <p>A misdiagnosis can be stressful and confusing. For people with type 1.5 diabetes, being misdiagnosed with type 2 diabetes might mean they don’t get the insulin they need in a timely manner. This can lead to worsening health and a greater likelihood of complications down the road.</p> <p>Getting the right diagnosis helps people receive the most appropriate treatment, save money, and reduce <a href="https://diabetesjournals.org/diabetes/article/73/Supplement_1/55-OR/155112/55-OR-Diabetes-Distress-among-Persons-Living-with">diabetes distress</a>.

Does eating ham, bacon and beef really increase your risk of developing type 2 diabetes?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a></em></p> <p>That lunchtime staple, the humble ham sandwich, has come in for a bashing in the press recently. According to <a href="https://www.theguardian.com/society/article/2024/aug/20/two-slices-of-ham-a-day-can-raise-type-2-diabetes-risk-by-15-research-suggests">many</a> <a href="https://www.dailymail.co.uk/health/article-13761253/Eating-ham-daily-linked-increase-risk-diabetes.html">reports</a>, eating two slices of ham a day can increase your risk of developing type 2 diabetes.</p> <p>But what’s the science behind these headlines?</p> <p>The research offers a more complex picture. <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(24)00179-7/fulltext">A new study</a> from the University of Cambridge highlighted an association between developing type 2 diabetes and eating processed meat like ham and bacon, and red meat such as beef and lamb.</p> <p>This led to headlines suggesting the risk was mainly linked to <a href="https://www.telegraph.co.uk/news/2024/08/21/ham-sandwich-processed-meat-fresh-risk-link-type-2-diabetes/">ham sandwiches</a>. This seems to have come from the <a href="https://www.cam.ac.uk/research/news/red-and-processed-meat-consumption-associated-with-higher-type-2-diabetes-risk">press release</a>, which used ham as the example to quantify the amount of processed meat associated with a 15% increased risk of developing type 2 diabetes over ten years.</p> <p>The research found that this risk was linked to eating an extra 50g of processed meat every day, which happens to equate to two slices of ham. A useful example thus appears to have been taken up by the media as the main cause, perhaps ignoring some of the key messages coming from the study.</p> <p>So, can processed and red meat really increase your risk of developing type 2 diabetes?</p> <p>The <a href="https://www.diabetes.org.uk/diabetes-the-basics/types-of-diabetes/type-2/diabetes-risk-factors">biggest risk factors</a> linked to developing type 2 diabetes are being over 40, having family members with type 2 diabetes, being of South Asian or African descent, or having a higher body weight – and especially a larger waist.</p> <figure><iframe src="https://www.youtube.com/embed/EsOBcx2bJqU?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The Cambridge study used data from nearly 2 million people from 31 studies. Participants were followed for an average of ten years. During this time, around one in 20 people developed type 2 diabetes.</p> <p>The research suggested that a 10% increase in the probability of developing type 2 diabetes was associated with every 100g of additional red meat eaten daily. Eating half as much extra processed meat every day was linked to an even greater increased risk of developing the disease.</p> <p>This is not the <a href="https://ajcn.nutrition.org/article/S0002-9165(23)66119-2/abstract">first time</a> that both processed and red meats have been linked with an increased risk of developing type 2 diabetes. However, the key strength of the Cambridge study was that it tried to control for many of the other factors linked to the disease, including smoking, having a higher body weight, dietary intake and exercise.</p> <p>However, the size of the increased risk is modest, considering few people included in the study ate 50g or more processed meat per day – meaning moderate ham consumption is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9908545/">no meaningful effect</a> on your risk.</p> <h2>What’s the link?</h2> <p>Processed meat has been linked to increased risk of type 2 diabetes because of its nitrate and salt content – additives that are used to cure many processed meats.</p> <p>Nitrates and salt in processed meats have also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893523/">been linked to</a> an increased risk of developing colon cancer. In fact, the World Health Organization classifies the additives as <a href="https://www.who.int/news-room/questions-and-answers/item/cancer-carcinogenicity-of-the-consumption-of-red-meat-and-processed-meat">group 1 carcinogens</a>, which means they can cause a range of cancers.</p> <p>The mechanism linking processed meat to cancer seems to be similar to how it might be linked to type 2 diabetes. During digestion, processed meat produces <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6294997/">N-nitroso chemicals</a>, which can damage cells. This can lead to inflammation and affects how insulin, the hormone that controls blood glucose (sugar), works. This in turn can lead to <a href="https://www.niddk.nih.gov/health-information/diabetes/overview/what-is-diabetes/prediabetes-insulin-resistance">insulin resistance</a>, when cells in your muscles, fat and liver don’t respond well to insulin and can’t easily take up glucose from your blood.</p> <p>Red meat, meanwhile, is <a href="https://www.healthline.com/nutrition/healthy-iron-rich-foods">rich in iron</a>. Research suggests that people with <a href="https://www.diabetes.org.uk/diabetes-the-basics/related-conditions/haemochromatosis-diabetes#:%7E:text=So%20a%20rise%20of%20iron,GP%20as%20soon%20as%20possible.">high levels of iron</a> are more likely to develop type 2 diabetes. However, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8744124/#:%7E:text=The%20WHO%20has%20recognised%20iron,being%20affected%20with%20this%20condition.">low levels of iron</a> are more of a health concern for the general population.</p> <p>Another potential link regarding red meat could be the way it is cooked.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5521980/">Previous studies</a> have suggested that charred meat, cooked over an open flame or at high temperature, is also linked to an increased risk of developing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5911789/">type 2 diabetes</a>. Charring meat leads to formation of toxic chemicals such as <a href="https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/heterocyclic-amine#:%7E:text=Heterocyclic%20amines%20are%20aromatic%20compounds,of%20reactions%20called%20Maillard%20reactions.">heterocyclic aromatic amines</a> and harmful compounds like <a href="https://www.healthline.com/nutrition/advanced-glycation-end-products">advanced glycation end products</a>, both of which have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/21709297/">insulin resistance and type 2 diabetes</a>.</p> <h2>Bye-bye barbecues and bacon butties?</h2> <p>The key message is reduction, rather than avoidance. The UK government nutritional recommendations offer sound advice: limit your combined intake of red and processed meat to no more than <a href="https://www.nhs.uk/live-well/eat-well/food-types/meat-nutrition/#:%7E:text=Red%20meat%20and%20processed%20meat&amp;text=If%20you%20currently%20eat%20more,%2C%20veal%2C%20venison%20and%20goat.">an average of 70g per day</a>.</p> <p>But these guidelines also suggest that red meat can be a valuable source of iron. So, if you decide to stop eating red meat, you should eat alternative sources of iron such as beans, lentils, dark green vegetables and fortified cereals.</p> <p>This needs to be done as part of a carefully planned diet. Non-meat sources of iron are more difficult for our bodies to absorb so should be eaten with a source of vitamin C, found in green vegetables and citrus fruit.</p> <p>The best advice to reduce your risk of developing type 2 diabetes is to maintain a healthy weight – consider losing weight if you have a higher body weight – and be as physically active as possible.</p> <p>A healthy diet should be based on plenty of vegetables, fruit, beans, peas, lentils, nuts and seeds, along with some wholegrain foods, some dairy products, fish and white meat (or vegetarian alternatives) – plus moderate amounts of red meat and minimal processed meat. This will help reduce your risk of type 2 diabetes, <a href="https://www.bhf.org.uk/informationsupport/support/healthy-living/healthy-eating">heart disease</a>, and <a href="https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/does-having-a-healthy-diet-reduce-my-risk-of-cancer">many cancers</a> – as well being more <a href="https://www.bda.uk.com/static/539e2268-7991-4d24-b9ee867c1b2808fc/a1283104-a0dd-476b-bda723452ae93870/one%20blue%20dot%20reference%20guide.pdf">environmentally sustainable</a>.</p> <p>But if you have a penchant for ham sandwiches, rest assured you can continue to indulge as an occasional treat.

Why do dogs have different coats? Experts explain – and give grooming tips for different types

<p><em><a href="https://theconversation.com/profiles/susan-hazel-402495">Susan Hazel</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>Dog hair comes in many varieties, from shaggy to short, curly to straight. If you live with a dog, you live with their hair – on your couch, in your clothes, it’s everywhere!</p> <p>Beyond colour, have you ever wondered what’s behind the differences in coat type?</p> <p>We actually know quite a lot about why dogs have different coats, and it comes down to their genes.</p> <h2>What are the main coat types in dogs?</h2> <p>The three main features of dog coats are how long the hairs are, whether they are curly or straight, and whether they have extra flourishes. The flourishes are called “furnishings”, and can include a hairy moustache and shaggy eyebrows.</p> <p>Combinations of these three features result in seven different coat types in dogs: short, wire, wire and curly, long, long with furnishings, curly, and curly with furnishings.</p> <p>We know from a <a href="https://www.science.org/doi/abs/10.1126/science.1177808">study of more than 1,000 dogs with varying coats</a> that differences in only three genes are responsible for this variety.</p> <p>The gene responsible for long hair (called FGF5) is <a href="https://learn.genetics.utah.edu/content/basics/patterns">recessive</a>, meaning dogs must have two copies of the mutated gene to have long hair. <a href="https://doi.org/10.1073/pnas.1402862111">In humans</a>, the same gene has been identified in families with excessively long eyelashes.</p> <p>Curly coats in dogs are related to a gene called <a href="https://www.pawprintgenetics.com/products/tests/details/173/">KRT71</a>, which affects keratin, a protein involved in hair formation. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2974189/">Mutations in this gene</a> in cats result in hairless (Sphynx) or curly-haired (Devon Rex) breeds.</p> <p>The gene responsible for furnishings (<a href="https://medlineplus.gov/genetics/gene/rspo2/">RSPO2</a>) is involved in establishing hair follicles. <a href="https://www.healthline.com/health/hair-follicle">Hair follicles</a> are small pockets in the skin that grow hair.</p> <p>Variations in these three genes could explain the coat type in most (but not all!) of the dogs tested. For example, the long coat of the Afghan hound is not explained by these three genes. Further study is needed to identify less common mutations and genes controlling the coat in these dogs.</p> <p>The earliest dog breeds would have been short-haired, as a result of the “wild-type” genes. Later changes would have arisen through mutation and deliberate selection <a href="https://theconversation.com/managing-mutations-of-a-species-the-evolution-of-dog-breeding-96635">through modern breeding practices</a>.</p> <p>If all three mutations are present, the dog has a long, curly coat with furnishings. An example is the Bichon Frisé.</p> <h2>What else varies in dog coats?</h2> <p>Dog coat types can also be single or double. In a double-coated breed such as a Labrador, there is a longer coarse layer of hairs and a softer and shorter undercoat. Wolves and ancestral dogs are single-coated, and the double coat is a result of a <a href="https://www.mdpi.com/2073-4425/10/5/323">mutation in chromosome 28</a>.</p> <p>In the Labrador, the mutation was probably selected for as they were bred to <a href="https://www.gov.nl.ca/releases/2023/exec/0525n07/">retrieve fishing nets in Canada</a>. The double coat is a great insulator and helps them to stay warm, even in icy water.</p> <h2>Why does it matter what kind of coat a dog has?</h2> <p>We know with climate change our world is going to get hotter. Dogs with a double coat are less able to tolerate heat stress, as their hair prevents heat loss.</p> <p>In a study of dogs <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/avj.13296">suffering heat-related illness</a>, most of the 15 breeds at higher risk had double coats. The death rate in these dogs was 23%. We can only imagine how it must feel going out on a 40 degree day wearing a thick fur coat.</p> <p>Dogs with a double coat shed more hair than dogs with a single coat. This means even short-haired breeds, like the Labrador retriever, can shed an astonishing amount of hair. If you can’t tolerate dog hair, then a dog with a double-coat may not suit you.</p> <p>When we think of wool we think of sheep, but in the past <a href="https://www.si.edu/stories/woolly-dog-mystery-unlocked">woolly dogs were kept for their wool</a> that was <a href="https://www.science.org/doi/10.1126/science.adi6549">woven by Indigenous groups</a> and used to make blankets.</p> <p>A dog’s coat also affects how much time and effort is needed for grooming. Dogs with long or curly hair with furnishings are likely to need more time invested in their care, or visits to a professional groomer.</p> <p>Designer dogs (cross-bred dogs often crossed with a poodle, such as groodles), are likely to be curly with furnishings. In a US study, people with designer dogs reported meeting their dogs’ maintenance and grooming requirements was <a href="https://www.mdpi.com/2076-2615/12/23/3247">much harder than they expected</a>.</p> <p>It’s not just bank balances and the time needed that can suffer. If people are unable to cope with the demands of grooming long-haired dogs, lack of grooming can cause welfare problems. A study of animal cruelty cases in New York found <a href="https://www.frontiersin.org/articles/10.3389/fvets.2022.827348/full">13% involved hair matting</a>, with some hair mats causing strangulation wounds and 93% of affected dogs having long hair.</p> <h2>How can you prevent problems?</h2> <p>If you have a curly- or long-haired breed of dog, it will help to train them to like being brushed from an early age. You can do this by counter-conditioning so they have a positive emotional response to being groomed, rather than feeling anxious. First show the brush or lightly brush them, then give them a treat. They learn to associate being brushed with something positive.</p> <p>If you take your dog to the groomer, it’s very important their first experience is positive. A scary or painful incident will make it much more difficult for future grooming.</p> <p>Is your dog difficult to groom or hard to get out of the car at the groomers? It’s likely grooming is scary for them. Consulting a dog trainer or animal behaviourist who focuses on positive training methods can help a lot.</p> <p>Keeping your dog well groomed, no matter their hair type, will keep them comfortable. More important than looking great, feeling good is an essential part of dogs living their best lives with us.<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/232480/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/susan-hazel-402495">Susan Hazel</a>, Associate Professor, School of Animal and Veterinary Science, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, Research Fellow, Animal Welfare Science Centre, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Yes, adults can develop food allergies. Here are 4 types you need to know about

<p><em><a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a></em></p> <p>If you didn’t have food allergies as a child, is it possible to develop them as an adult? The short answer is yes. But the reasons why are much more complicated.</p> <p>Preschoolers are about <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">four times more likely to have a food allergy</a> than adults and are more likely to grow out of it as they get older.</p> <p>It’s hard to get accurate figures on adult food allergy prevalence. The Australian National Allergy Council reports <a href="https://nationalallergycouncil.org.au/about-us/our-strategy">one in 50 adults</a> have food allergies. But a US survey suggested as many as <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">one in ten adults</a> were allergic to at least one food, with some developing allergies in adulthood.</p> <h2>What is a food allergy</h2> <p><a href="https://pubmed.ncbi.nlm.nih.gov/36509408/">Food allergies</a> are immune reactions involving <a href="https://www.aaaai.org/tools-for-the-public/allergy,-asthma-immunology-glossary/immunoglobulin-e-(ige)-defined">immunoglobulin E (IgE)</a> – an antibody that’s central to triggering allergic responses. These are known as “IgE-mediated food allergies”.</p> <p>Food allergy symptoms that are <em>not</em> mediated by IgE are usually delayed reactions and called <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">food intolerances or hypersensitivity</a>.</p> <p>Food allergy symptoms can include hives, swelling, difficulty swallowing, vomiting, throat or chest tightening, trouble breathing, chest pain, rapid heart rate, dizziness, low blood pressure or <a href="https://www.allergy.org.au/hp/papers/acute-management-of-anaphylaxis-guidelines?highlight=WyJhbmFwaHlsYXhpcyJd">anaphylaxis</a>.</p> <p>IgE-mediated food allergies can be life threatening, so all adults need an <a href="https://allergyfacts.org.au/allergy-management/newly-diagnosed/action-plan-essentials">action management plan</a> developed in consultation with their medical team.</p> <p>Here are four IgE-mediated food allergies that can occur in adults – from relatively common ones to rare allergies you’ve probably never heard of.</p> <h2>1. Single food allergies</h2> <p>The most <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">common IgE-mediated food allergies</a> in adults in a US survey were to:</p> <ul> <li>shellfish (2.9%)</li> <li>cow’s milk (1.9%)</li> <li>peanut (1.8%)</li> <li>tree nuts (1.2%)</li> <li>fin fish (0.9%) like barramundi, snapper, salmon, cod and perch.</li> </ul> <p>In these adults, about 45% reported reacting to multiple foods.</p> <p>This compares to <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">most common childhood food allergies</a>: cow’s milk, egg, peanut and soy.</p> <p>Overall, adult food allergy prevalence appears to be increasing. Compared to <a href="https://pubmed.ncbi.nlm.nih.gov/14657884/">older surveys published in 2003</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/15241360/">2004</a>, peanut allergy prevalence has increased about three-fold (from 0.6%), while tree nuts and fin fish roughly doubled (from 0.5% each), with shellfish similar (2.5%).</p> <p>While new <a href="https://pubmed.ncbi.nlm.nih.gov/38214821/">adult-onset food allergies are increasing</a>, childhood-onset food allergies are also more likely to be retained into adulthood. Possible reasons for both <a href="https://pubmed.ncbi.nlm.nih.gov/38214821/">include</a> low vitamin D status, lack of immune system challenges due to being overly “clean”, heightened sensitisation due to allergen avoidance, and more frequent antibiotic use.</p> <h2>2. Tick-meat allergy</h2> <p>Tick-meat allergy, also called α-Gal syndrome or mammalian meat allergy, is an allergic reaction to galactose-alpha-1,3-galactose, or α-Gal for short.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/33529984/">Australian immunologists first reported</a> links between α-Gal syndrome and tick bites in 2009, with cases also reported in the United States, Japan, Europe and South Africa. The <a href="https://pubmed.ncbi.nlm.nih.gov/38318181/">US Centers for Disease Control estimates</a> about 450,000 Americans <a href="https://www.cdc.gov/mmwr/volumes/72/wr/mm7230a2.htm">could be affected</a>.</p> <p>The α-Gal contains a carbohydrate molecule that is bound to a <a href="https://pubmed.ncbi.nlm.nih.gov/38318181/">protein</a> molecule in <a href="https://alphagalinformation.org/what-is-a-mammal/">mammals</a>.</p> <p>The IgE-mediated allergy is triggered after repeated bites from ticks or <a href="https://www.insectshield.com/pages/chiggers">chigger mites</a> that have bitten those mammals. When tick saliva crosses into your body through the bite, antibodies to α-Gal are produced.</p> <p>When you subsequently eat foods that contain α-Gal, the allergy is triggered. These triggering foods include meat (lamb, beef, pork, rabbit, kangaroo), dairy products (yoghurt, cheese, ice-cream, cream), <a href="https://en.wikipedia.org/wiki/Gelatin">animal-origin gelatin</a> added to gummy foods (jelly, lollies, marshmallow), prescription medications and over-the counter supplements containing gelatin (<a href="https://www.drugs.com/inactive/gelatin-57.html">some antibiotics, vitamins and other supplements</a>).</p> <p>Tick-meat allergy reactions can be hard to recognise because they’re usually delayed, and they can be severe and include anaphylaxis. Allergy <a href="https://www.allergy.org.au/patients/food-allergy/mammalian-meat-tick-faq">organisations produce management guidelines</a>, so always discuss management with your doctor.</p> <h2>3. Fruit-pollen allergy</h2> <p>Fruit-pollen allergy, called pollen food allergy syndrome, is an <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">IgE-mediated allergic reaction</a>.</p> <p>In susceptible adults, pollen in the air provokes the production of IgE antibodies to antigens in the pollen, but these antigens are similar to ones found in some fruits, vegetables and herbs. The problem is that <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">eating those plants</a> triggers an allergic reaction.</p> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">most allergenic tree pollens</a> are from birch, cypress, Japanese cedar, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/latex-allergy">latex</a>, grass, and ragweed. Their pollen can cross-react with <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">fruit and vegetables</a>, including kiwi, banana, mango, avocado, grapes, celery, carrot and potato, and some herbs such as caraway, coriander, fennel, pepper and paprika.</p> <p>Fruit-pollen allergy is not common. Prevalence <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">estimates are between 0.03% and 8%</a> depending on the country, but it can be life-threatening. Reactions range from itching or tingling of lips, mouth, tongue and throat, called <a href="https://pubmed.ncbi.nlm.nih.gov/20306812/">oral allergy syndrome</a>, to mild <a href="https://www.allergy.org.au/patients/skin-allergy/urticaria-hives">hives</a>, to anaphylaxis.</p> <h2>4. Food-dependent, exercise-induced food allergy</h2> <p>During heavy exercise, the stomach produces less acid than usual and gut permeability increases, meaning that small molecules in your gut are more likely to escape across the membrane into your blood. These include food molecules that trigger an IgE reaction.</p> <p>If the person already has IgE antibodies to the foods eaten before exercise, then the risk of triggering food allergy reactions is increased. This allergy is called <a href="https://pubmed.ncbi.nlm.nih.gov/37893663/">food-dependent exercise-induced allergy</a>, with symptoms ranging from hives and swelling, to difficulty breathing and anaphylaxis.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/30601082/">Common trigger foods include</a> wheat, seafood, meat, poultry, egg, milk, nuts, grapes, celery and other foods, which could have been eaten many hours before exercising.</p> <p>To complicate things even further, allergic <a href="https://pubmed.ncbi.nlm.nih.gov/33181008/">reactions can</a> occur at lower levels of trigger-food exposure, and be more severe if the person is simultaneously taking non-steroidal inflammatory medications like aspirin, drinking alcohol or is sleep-deprived.</p> <p>Food-dependent exercise-induced allergy is extremely rare. Surveys have estimated prevalence as between <a href="https://www.sciencedirect.com/science/article/pii/S1555415517300259">one to 17 cases per 1,000 people worldwide</a> with the highest prevalence between the teenage years to age 35. Those affected often have other allergic conditions such as hay fever, asthma, allergic conjunctivitis and dermatitis.</p> <h2>Allergies are a growing burden</h2> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/36509408/">burden on physical health, psychological health</a> and health costs due to food allergy is increasing. In the US, this <a href="https://pubmed.ncbi.nlm.nih.gov/38393624/">financial burden was estimated as $24 billion per year</a>.</p> <p>Adult food allergy needs to be taken seriously and those with severe symptoms should wear a medical information bracelet or chain and carry an <a href="https://www.healthdirect.gov.au/how-to-use-an-adrenaline-autoinjector-epipen-anapen">adrenaline auto-injector pen</a>. Concerningly, surveys suggest only <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">about one in four adults</a> with food allergy have an adrenaline pen.</p> <p>If you have an IgE-mediated food allergy, discuss your management plan with your doctor.

Could not getting enough sleep increase your risk of type 2 diabetes?

<p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936"><em>University of Technology Sydney</em></a></em></p> <p>Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">recent study</a> that found people who sleep less than six hours a night are at higher risk of type 2 diabetes.</p> <p>So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex.</p> <h2>The study</h2> <p>Researchers analysed data from the <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a>, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade.</p> <p>The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk.</p> <p>As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets.</p> <p>Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category.</p> <p>The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours.</p> <p>One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less.</p> <p>Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations.</p> <h2>Why might short sleep increase diabetes risk?</h2> <p>In people with <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">type 2 diabetes</a>, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body.</p> <p>We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But <a href="https://doi.org/10.7759/cureus.23501">previous research</a> has shown sleep-deprived people often have increased <a href="https://doi.org/10.1186/1476-511X-9-125">inflammatory markers</a> and <a href="https://doi.org/10.1007/s00125-015-3500-4">free fatty acids</a> in their blood, which <a href="https://doi.org/10.1007/s11892-018-1055-8">impair insulin sensitivity</a>, leading to <a href="https://doi.org/10.7759/cureus.23501">insulin resistance</a>. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes.</p> <p>Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5995632/">circadian rhythm</a>.</p> <p>This can interfere with the release of hormones like <a href="https://doi.org/10.1210/edrv.18.5.0317">cortisol, glucagon and growth hormones</a>. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses.</p> <p>These factors, and <a href="https://www.science.org/doi/10.1126/sciadv.aar8590">others</a>, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours.</p> <p>While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes.</p> <p>Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A <a href="https://doi.org/10.2337/dc14-2073">review</a> of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase.</p> <p>The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to <a href="https://doi.org/10.2337/dc15-0186">weight gain</a>, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be <a href="https://doi.org/10.1016/j.sleh.2017.07.013">overweight or obese</a>.</p> <h2>Good sleep, healthy diet</h2> <p>Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes.</p> <p>Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle.</p> <p>While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of <a href="https://www.who.int/initiatives/behealthy/healthy-diet">healthy eating</a> for overall health.</p> <p>The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">authors of the study</a> acknowledge it’s not always possible to get enough sleep, and suggest doing <a href="https://pubmed.ncbi.nlm.nih.gov/33137489/">high-intensity interval exercise</a> during the day may offset some of the potential effects of short sleep on diabetes risk.</p> <p>In fact, exercise <a href="https://doi.org/10.1016/j.jshs.2023.03.001">at any intensity</a> can improve blood glucose levels.<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/225179/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, Casual Academic, Faculty of Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, Senior Lecturer, School of Public Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The types of insurance that aren’t worth your while

<p>While it’s important to make sure you’ve been covered, some forms of insurance aren’t really worth your while in the long run. We’ve taken a look at several types of insurance you shouldn’t really bother with, why they’re not worth your money and how you can find an alternative. </p> <p>Yes, it’s essential to make sure you’re covered, but at the same time you don’t need to waste any money.</p> <p><strong>Extended warranties</strong></p> <p>Many a salesperson has made a customer fork out that little bit extra for an “extended warranty” to go with a major electronic purchase. The thing is though, in many cases the period of time covered by the warranty is actually exactly the level you’re automatically entitled to under consumer law.</p> <p><strong>Credit protection insurance</strong></p> <p>While this type of insurance can be useful and a way to insure yourself against the possibility of something happening to your income as the result of an injury or a condition, credit protection insurance has tendency to be pretty expensive. </p> <p>A more cost effective way to ensure your payments to your credit card, personal loans or mortgages are fulfilled would be to take out a life insurance or total and permanent disability insurance policy through your individual superannuation fund.</p> <p><strong>Funeral insurance</strong></p> <p>Many people see this as a good way to ease the financial burden on their family that comes with their passing, but in reality funeral insurance is quite expensive and the premiums add up every year. </p> <p>A far better option is a prepaid funeral, funeral bonds life insurance or even a special savings account with money set aside. Just make sure you let your family know!</p> <p><strong>ID theft insurance</strong></p> <p>This is one of those types of insurance that isn’t really protecting your from becoming a victim, rather helping you deal with the costs once it’s already happened. And what’s more, you bank is usually willing to cover the costs of credit card fraud, which is one of the major problems to be associated with ID theft. </p> <p>Instead of spending money on a policy you can protect yourself from ID theft by simply keeping your personal documents safe, shredding documents such as bank account statements before throwing them away, and using antivirus software that is up to date. You can also check your credit file each year to make sure nobody’s using your identity for fake accounts.</p> <p><em>Image credits: Getty Images </em></p>

8 reasons everyone should know their blood type

<p><strong>Why you should know your blood type</strong></p> <p>What’s in a blood type? Potentially a lot, according to research, including a review of studies published in the Wiley Interdisciplinary Reviews: Systems Biology and Medicine, that connects different blood groups to everything from risk of heart disease and dementia to urinary tract infections and the norovirus. </p> <p>While none of the studies are conclusive about cause and effect (they can’t say X blood type causes Y disease) and any increased risks are still pretty small, the research does highlight the importance of knowing your type – A, B, AB, or O – and how it could affect your wellbeing.</p> <p><strong>Blood clots: Type AB, A, and B increases risk</strong></p> <p>Danish researchers studied how blood type interacts with a genetic predisposition for deep-vein thrombosis (DVT), or blood clots in the lower legs that can travel to the lungs and become life-threatening. After analysing data on about 66,000 people over more than 30 years, they found that those with type AB, A, or B had a 40 per cent higher risk of DVT than people with type O, the most common type.</p> <p>When the scientists did further analysis to see which factors have the biggest impact on DVT risk on a population level, they found that an AB blood type contributed to about 20 per cent of blood clots; genetic mutations accounted for 11 per cent, being overweight accounted for 16 per cent, and smoking accounted for six per cent.</p> <p><strong>Heart disease: Type AB, B, and A all increase risk </strong></p> <p>People whose blood type is A, B, or AB have an increased risk of heart disease and shorter life spans than people who have type O blood, according to a large study published in BMC Medicine. After following more than 50,000 middle-age and elderly people for seven years, on average, researchers found that as many as nine per cent of cardiovascular deaths were attributed to having non-O blood types. </p> <p>However, as any doctor will tell you, lifestyle factors like weight, smoking and diet, which, unlike blood type, are modifiable, have a much greater impact on heart disease.</p> <p><strong>Stomach cancer: Types A and AB increases risk </strong></p> <p>Researchers have known for a while that people with blood type A are at risk for stomach cancer. But research published in BMC Cancer shows that people with blood type AB are also at risk. Using genetic data from a large number of cases and controls, researchers found a link between both blood types and gastric cancer in Chinese populations. A review of 39 previous studies confirmed their findings.</p> <p><strong>Fertility: Type O reduces it </strong></p> <p>Women with this blood type were twice as likely to have blood levels of the hormone FSH high enough to indicate low ovarian reserve, a measure of fertility, according to a study published in Human Reproduction. Researchers couldn’t say for sure why, though. Given that type O blood is the most prevalent, it doesn’t pay to worry too much about it. Age is a far more important risk factor for fertility problems.</p> <p><strong>Pregnancy risks </strong></p> <p>This has nothing to do with your “letter” blood type or the type determined by the ABO grouping system. This has to do with what’s known as the Rhesus (Rh) factor, which determines whether your blood type is positive or negative. This could cause complications in pregnant women if the baby’s Rh blood type is different from the mother’s. </p> <p>For instance, if the mother has a negative blood type and the baby has a positive one, the mother’s body can actually build up antibodies against the baby’s blood type. Luckily, this doesn’t affect the baby, but it could have a negative effect on future pregnancies. Fortunately, doctors can give pregnant women a shot early in their pregnancy that can prevent Rh-incompatibility problems.</p> <p><strong>Dementia and memory loss: Type AB increases risk </strong></p> <p>People with type AB blood have an 82 per cent greater risk for cognitive decline later in life, according to a study published in Neurology. That’s likely because they have larger amounts of what’s known as the Factor VIII protein, which helps with blood clotting. </p> <p>Study participants with higher levels of this protein were 24 per cent more likely to develop memory problems – regardless of their blood type – than people with lower levels. Blood type, however, is far from the only, or even most important, factor that affects your risk for cognitive decline.</p> <p><strong>Stroke: Type O has the lowest risk</strong></p> <p>People with a blood type other than O (the most common) have a higher risk of cardiovascular issues such as stroke, according to a study published in the Journal of Thrombosis and Haemostasis. Biologists are still investigating why this might be; one possible explanation is that non-O blood types contain more of the Von Willebrand factor, a protein that has been connected to blood clotting and stroke in the past.</p> <p><strong>Mosquitos like Type O blood </strong></p> <p>If you find yourself scratching bug bites all summer long, your blood type might be to blame. In a one small study, researchers found that type Os are up to twice as attractive to mosquitoes as type As, with type Bs falling somewhere in the middle. </p> <p><em>Image credits: Shutterstock</em></p> <p style="box-sizing: border-box; border: 0px; margin: 0px 0px 20px; outline: 0px; padding: 0px; vertical-align: baseline; line-height: 26px;"><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/8-reasons-everyone-should-know-their-blood-type" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

We found 3 types of food wasters, which one are you?

<p><em><a href="https://theconversation.com/profiles/trang-nguyen-1454838">Trang Nguyen</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/patrick-oconnor-109973">Patrick O'Connor</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p>Each year, Australian households discard about <a href="https://workdrive.zohopublic.com.au/external/06152b9ff5971843391f39fc4d32a847e56fb907c167a4a645887b0a4bc43000">2.5 million tonnes of food</a>. Most (73%) of this food waste <a href="https://www.sciencedirect.com/science/article/pii/S0959652622042081">ends up in landfill</a>.</p> <p>This is costly and contributes to <a href="https://pubmed.ncbi.nlm.nih.gov/37118273/">escalating greenhouse gas emissions</a>, because food waste rotting in landfill produces methane. So reducing household food waste and diverting it from landfill saves money, improves food security and benefits the environment.</p> <p>To address the problem, we need to understand how people generate and dispose of food waste. In <a href="https://doi.org/10.1016/j.foodqual.2023.105000">our new study</a>, we found households fell into three categories – based on the amount of food wasted, how much of that waste was avoidable and how it was sorted. These insights into consumer behaviour point to where the most worthwhile improvements can be made.</p> <figure><iframe src="https://www.youtube.com/embed/JvAFaD5f1Lo?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption></figcaption></figure> <h2>Three types of households</h2> <p>We conducted an online survey of 939 households in metropolitan Adelaide between April and May 2021.</p> <p>The sample closely matched the national Australian population in terms of gender, age and income.</p> <p>We asked about the types of food waste produced, the amount of food waste typically discarded in a week and motivations towards reducing and sorting food waste.</p> <p>We identified three distinct types of households:</p> <p><strong>Warriors</strong> are typically older and highly motivated to reduce and sort food waste. They generate minimal waste (9.6 litres per week), such as bones and vegetable peels, that is mostly unavoidable. This group comprised 39.6% of the sample.</p> <p><strong>Strugglers</strong> mainly consist of families with children who produce the largest amount of food waste (33.1 litres per week). They produce the highest proportion of avoidable food waste, such as uneaten fruits and vegetables, bread and cereals. They are moderately motivated to reduce and sort food waste, but more than half of their food waste still ends up in landfill. This group made up 19.6% of the sample.</p> <p><strong>Slackers</strong> are generally younger. They show little concern about reducing or sorting food waste. Slackers produce the smallest amount of food waste overall (9 litres a week), but the proportion of avoidable food waste (such as mixed leftovers) is significantly higher (38.9%) compared to warriors (24.5%). They are more than twice as likely to live in units, with 17.2% doing so, compared to just 7.8% of warriors. This group was 40.8% of the sample.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=361&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=361&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=361&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=454&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=454&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=454&amp;fit=crop&amp;dpr=3 2262w" alt="Graphic explainer showing the three types of households with their typical characteristics and food waste behaviours." /></a><figcaption><span class="caption">The three types of households with their typical characteristics and food waste behaviours.</span> <span class="attribution"><a class="source" href="https://doi.org/10.1016/j.foodqual.2023.105000">Trang Nguyen using Canva.com</a>, <a class="license" href="http://creativecommons.org/licenses/by-nc-nd/4.0/">CC BY-NC-ND</a></span></figcaption></figure> <h2>What can households do about their food waste?</h2> <p>Reducing household food waste involves changing behaviours in both food management (“upstream”) and waste management (“downstream”).</p> <p>Upstream measures aim to prevent food waste in the first place. For example, households can avoid buying or cooking too much food. Supporting households to plan and buy just the right amount of food is a great starting point.</p> <p>Once food waste has been produced, downstream measures come into play. The focus shifts to how we handle and dispose of this waste.</p> <p>When households engage in food waste recycling they <a href="https://doi.org/10.3390/su131911099">start thinking more</a> about their behaviour including purchasing and cooking.</p> <p>In Australia, food waste management is mainly the responsibility of local councils.</p> <p>There are three ways to target household food waste management and drive behavioural change:</p> <ul> <li> <p>providing kerbside collection of food organics and garden organics, also known as “FOGO”</p> </li> <li> <p>changing social norms around food waste</p> </li> <li> <p>offering economic incentives and disincentives.</p> </li> </ul> <h2>1. Providing a FOGO system</h2> <p>Councils should provide this option at a minimum. This ensures sufficient infrastructure is available to support motivated households to sort food waste.</p> <p>Unfortunately <a href="https://experience.arcgis.com/experience/e6b5c78e1dac47f88e7e475ffacfc49b">fewer than half of Australian councils</a> provide a garden organics system and only a quarter of councils provide a FOGO system.</p> <p>You can explore <a href="https://experience.arcgis.com/experience/e6b5c78e1dac47f88e7e475ffacfc49b">the FOGO interactive map</a> to see how your area stacks up.</p> <p><a href="https://www.greenindustries.sa.gov.au/resources/adelaide-metro-kerbside-waste-performance-report-2021-22">Most councils in metropolitan Adelaide</a> provide access to food waste recycling through the FOGO bin. But <a href="https://doi.org/10.1016/j.jclepro.2022.134636">our research</a> indicates more than half of household food waste still ends up in landfill. So we need additional programs to promote more sustainable behaviours.</p> <h2>2. Changing social norms</h2> <p>Social norms, the unspoken rules about what behaviours are deemed appropriate, can drive behavioural change.</p> <p>Examples of promoting social norms around food waste reduction include a <a href="https://www.stopfoodwaste.com.au/stop-food-waste-nationwide-consumer-campaign-summit-communique/">nationwide consumer campaign</a> on stopping food waste and the <a href="https://www.cityofadelaide.com.au/resident/recycling-waste/kitchen-caddies/">kitchen caddy</a> for benches to increase convenience for collecting food waste.</p> <p>But our research suggests some groups, like slackers, remain unmotivated without additional incentives. Economic incentives might motivate this group to engage in more sustainable behaviours.</p> <h2>3. Economic incentives</h2> <p>Currently, Australians pay for waste management through their council rates. This is a “pay-as-you-own” system.</p> <p>The cost is determined by the property’s value, regardless of the amount of waste generated. Renters indirectly contribute to this cost by paying rent.</p> <p>Neither owner-occupiers nor renters have any incentive to reduce waste generation when the cost is levied on property value rather than the amount of waste.</p> <p>An alternative approach gaining momentum in other parts of the world is the “pay-as-you-throw” approach, such as <a href="https://www.collectors2020.eu/wcs-ppw/stockholm-se/">Stockholm</a> and <a href="https://pocacito.eu/sites/default/files/WasteCharging_Taipei.pdf">Taipei</a>. This system charges households based on the weight of their waste, usually the general waste that needs to be discarded in landfill, while the collection of food waste and other recyclables remains free to encourage waste sorting.</p> <p>Recent <a href="https://doi.org/10.1016/j.jclepro.2023.137363">research</a> in Italy shows pay-as-you-throw schemes result in significant reductions in both the quantity of waste and costs associated with waste disposal in many Italian municipalities.</p> <p>The reduced costs flow on to savings for councils that could potentially reduce waste management fees passed on to homeowners and renters through council rates. Giving households incentives to reduce waste and find alternatives to disposal encourages residents to place a higher value on food that may otherwise be sent to landfill.</p> <h2>Reducing food waste is a win-win</h2> <p>Tackling food waste is a win-win for people and the planet. It’s worth using various approaches to encourage people to change their behaviour.</p> <p>Our findings can help inform the design of interventions aimed at reducing and sorting food waste in specific segments of the Australian population.<!-- Below is The Conversation's page counter tag.

The best cruise cabin for every type of need

<p><strong>So many options</strong></p> <p>Cruise accommodations – also known as staterooms or cabins – are your home away from home while at sea. Far from a one-size-fits-all decision, there are numerous factors to consider when determining the best rooms on a cruise ship to fit your and your companions’ needs.</p> <p>From size to location to view and beyond, there are many things to keep in mind when selecting your stateroom, says Gianluca Corneli, hotel director at Royal Caribbean International. “How many will stay in the room? Is your room a place to hang out or just where you sleep?” Also, think about what you’d like to be near on the ship. “For example, consider if you would like to be near the elevator for convenience or prefer a location down the hallway with fewer guests passing by,” she says. Also factor in any ways you’d like to elevate your stay, like maybe a balcony or a suite for your next Caribbean cruise.</p> <p>It’s no wonder that some of the best cruise lines offer up to 28 different types of rooms on a single ship – they want to ensure there’s an ideal solution for every guest. Let’s focus on upgrading your room choice to the perfect fit for your specific needs.</p> <p><strong>Best for avoiding seasickness</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: the middle of the ship, on a low deck</p> <p>Picture a ship like a seesaw – the most movement will be felt on either end, while the middle stays fairly even-keel. “Middle and low, that’s where you want to be,” says cruise expert Dori Saltzman, senior editor with trade publication Travel Market Report. “While you don’t need to be on the absolute lowest passenger deck, you don’t want to go above the middle of the ship (vertical wise). You also want to try to be as middle (horizontal wise) as possible.</p> <p>If cabins in the middle of the ship aren’t available, she says to choose aft over forward, because the more forward a cabin is, the more you’ll feel the motion of the ocean. And while this may seem counter-intuitive, be sure to book a cabin with a window or balcony, so you can keep your eyes on the horizon if you start feeling queasy.</p> <p><strong>Best for great views</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: a cabin with a balcony, preferably at the back of the ship</p> <p>While you can always go to the upper decks of any ship for 360-degree views of your surroundings, there’s no greater cruise ship luxury than enjoying the scenery from your own private balcony. They may also be called verandah cabins. Balconies are the perfect place to enjoy a cup of coffee in the morning or glass of champagne during a spectacular sunset and pretend you’re all alone at sea.</p> <p>And some of the absolute best rooms on a cruise ship are located at the rear, where you’ll also be treated to the photo-worthy wake left behind, which is a fun way to mark your ship’s progress. Balconies are also nice for having access to fresh air when you want it, it can be very soothing to listen to the sounds of the ocean from your stateroom, and you’ll have a better chance of spotting wildlife along your cruise too.</p> <p><strong>Best for light sleepers</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: a deck filled with other guest cabins and away from elevators</p> <p>Finding the best rooms on a cruise ship for light sleepers usually takes a little research, but that due diligence will pay off come bedtime. “You need your cabin to be located away from any bank of elevators, but also away from crew entrances,” says Saltzman. So being surrounded by other cabins of people who want to sleep too is a safe bet. “You also don’t want your cabin to be located above the ship’s main theatre, underneath any restaurants where you can hear the chairs scraping on the floor or under/over any of the lounges that have music late into the night.”</p> <p>Finally, you don’t want to be on a low deck that’s too aft or too forward, as you may end up above the engines or the anchor, which makes a lot of noise when it’s lowered and raised. You may feel a bit like Goldilocks trying to choose that perfect cabin on your next romantic cruise, but the reward of peace and quiet will be priceless.</p> <p><strong>Best for a little more space</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: a forward-facing cabin</p> <p>While you aren’t likely to find a balcony on a forward-facing cabin, you may find more interior space than similarly priced mid-ship cabins. Why? There are some odd angles in forward-facing cabins that the designers had to work around, thanks to the slanted style of the front of a ship. Those odd angles may work in your favour when it comes to square footage.</p> <p>It’s important to note that while these are some of the best rooms on a cruise ship for extra space, you will experience the most movement in a front-facing cabin, so this choice is not an ideal position for anyone prone to motion sickness.</p> <p><strong>Best for cruising with little kids</strong></p> <p>Most cruise lines offer family-friendly cruises and specific cabins suited for kids, which can be a mix of in-room amenities and proximity to other areas of the ship children will love. “On Disney’s ships, all cabins have two bathrooms, one with a sink and toilet and the other with a shower/bath combo (a small minority of rooms do not have the tub) for families that need the little one to be able to take a bath, while everyone else is still able to wash up,” says Saltzman. </p> <p>“Another good option is the Family Harbour cabins on Carnival’s Vista-class ships (Vista, Horizon, Panorama) and Excel-class ships (Mardi Gras, Celebration). Similar to the Disney cabins, these have two bathrooms, one a full one with a shower, sink and toilet, and the other with a sink and shower/tub combo.”</p> <p><strong>Best for staying on a budget</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: an interior cabin</p> <p>Unless you’re worried about feeling claustrophobic – since there will be no porthole or window to the outside world – an interior cabin is a nice option for saving money (we’re talking $300 for 7-day cruises). Not only is it the lowest-priced cabin type, which means you’ll have more funds to put toward excursions, a drink package or souvenirs, but you’ll also be able to take midday naps or sleep in later because there won’t be any light sneaking in.</p> <p>Another positive is that an interior cabin might encourage you to spend more of your free time roaming around the ship, meeting other people and getting more involved in activities, since you may not find it desirable to spend your time beyond sleeping and showering in a windowless box.</p> <p><strong>Best for mobility disabilities </strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: an accessible stateroom</p> <p>For passengers with limited mobility or no mobility, most major cruise lines offer accessible staterooms in a variety of room types (inside cabin, ocean view and balcony). These options do vary based on the cruise line and the age of the ship, so it’s best to research this in advance and factor the accessible options available into your cruise planning process.</p> <p>Accessible rooms tend to be larger than standard cabins to accommodate wheelchair or scooter users, and they also feature larger bathrooms. Additionally, some rooms will have emergency-call buttons or specific amenities for hearing or vision-impaired guests. For instance, the fully accessible rooms on Holland America Line provide adequate turning space, accessibility routes throughout the room, roll-in showers, wheelchair access on both sides of the bed, handlebars in the shower and hand-held shower heads, says Sissel Bergersen, director of rooms division, Holland America Line. Before you lock in a booking, it may be best to call the cruise line and explain your needs so they can help steer you toward the perfect cabin.</p> <p><strong>Best for being spoiled rotten</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: a cabin with butler service or a spa cabin</p> <p>For travellers who like adult-only cruises or who are yearning for a little extra pampering, the best rooms on a cruise ship fall into one of two categories. The first is a suite that comes with butler service, where you’ll have someone helping with all the details you don’t want to spend your precious holiday time tending to – like reserving prime-time dinner slots at specialty restaurants, booking shore excursions, packing and unpacking and even drawing rose petal bubble baths. Rooms at this level may also come with exclusive access to private pools, clubs and lounges with more luxurious touches and solitude than you’ll find elsewhere on the ship.</p> <p>The other category that’s becoming increasingly popular is spa suites. On Norwegian Cruise Line, the Haven Spa Suite, Spa Club Balcony Suites and Spa Balcony (available on the Norwegian Escape, Norwegian Bliss and Norwegian Epic) have varying amenities that range from more tranquil room décor with an oversized shower and body spray jets to priority access to Mandara Spa. And on Celebrity Cruises, the AquaClass staterooms are focused on wellness, with a pillow menu, complimentary fitness pass, preferential rates on spa packages, healthy room-service menu options, an exclusive restaurant, a spa concierge, access to the SEA Thermal Suite and a yoga mat for use onboard.</p> <p><strong>Best for solo cruisers</strong></p> <p><em><span style="text-decoration: underline;">Choose</span></em>: a cruise line that offers single rooms or waives single supplements</p> <p>Solo cruises are a wonderful experience, yet so many cruise lines penalise single cruisers by forcing them to pay a ‘single supplement.’ This surcharge is added to the fare of a solo passenger, since cruise room pricing is generally based on double occupancy. This fee can be an additional 10 per cent all the way up to a full 100 per cent of the rate, making solo cruising unaffordable for many travellers.</p> <p>Instead, look for cruise lines that offer single staterooms, like Celebrity, which has the Edge Single Stateroom with Infinite Veranda (available on Celebrity Edge, Celebrity Apex, Celebrity Beyond and Celebrity Ascent) and the Single Inside Stateroom on Celebrity Silhouette. Other cruise lines, including Holland America Line, Royal Caribbean and Norwegian Cruise Line, also offer single cabins – these special solo and studio cabins aren’t subject to single supplements. Occasionally, you may even find cruise lines running special promotions and waiving their single supplement for a regular-size room.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/travel/cruising/the-best-cruise-cabin-for-every-type-of-need" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Why certain types of music make our brains sing, and others don’t

<p>A few years ago, Spotify published an online <a href="https://www.francetvinfo.fr/culture/musique/spotify-devoile-une-cartographie-des-gouts-musicaux_3320877.html">interactive map</a> of musical tastes, sorted by city. At the time, <a href="https://open.spotify.com/artist/5TEGxYftTkeKmLXkZjHNUE">Jeanne Added</a> prevailed in Paris and Nantes, and London was partial to local hip hop duo <a href="https://open.spotify.com/artist/31lnFZEM6ysvjOx59VyxRE">Krept and Kronan</a>. It is well established that music tastes vary over time, by region and even by social group. However, most brains look alike at birth, so what happens in them that causes us to end up with such disparate music tastes?</p> <h2>Emotions – a story of prediction</h2> <p>If one presented you with a unknown melody and suddenly stopped it, you could be able to sing the note you think fit the best. At least, professional musicians could! In a <a href="https://www.jneurosci.org/content/41/35/7449">study</a> published in the Journal of Neuroscience in September 2021, we show that similar prediction mechanisms are happening in the brain every time we listen to music, whithout us being necessarly conscious of it. Those predictions are generated in the auditory cortex and merged with the note that was actually heard, resulting in a “prediction error”. We used this prediction error as a sort of neural score to measure how well the brain could predict the next note in a melody.</p> <p>Back in <a href="https://books.google.fr/books/about/Emotion_and_Meaning_in_Music.html?id=HuWCVGKhwy0C&amp;redir_esc=y">1956</a>, the US composer and musicologist Leonard Meyer theorised that emotion could be induced in music by a sense of satisfaction or frustration derived from the listener’s expectations. Since then, academic advances have helped identify a link between musical expectations and other more complex feelings. For instance, participants in <a href="https://onlinelibrary.wiley.com/doi/10.1111/cogs.12477">one study</a> were able to memorize tone sequences much better if they could first accurately predict the notes within.</p> <p>Now, basic emotions (e.g., joy, sadness or annoyance) can be broken down into two fundamental dimensions, valence and psychological activation, which measure, respectively, how positive an emotion is (e.g., sadness versus joy) and how exciting it is (boredom versus anger). Combining the two helps us define these basic emotions. Two studies from <a href="https://link.springer.com/article/10.3758/s13415-013-0161-y">2013</a> and <a href="http://webprojects.eecs.qmul.ac.uk/marcusp/papers/SauveEtAl2018.pdf">2018</a> showed that when participants were asked to rank these two dimensions on a sliding scale, there was a clear relationship between prediction error and emotion. For instance, in those studies, music notes that were less accurately predicted led to emotions with greater psychological activation.</p> <p>Throughout the history of <a href="https://www.nature.com/articles/nrn1406">cognitive neuroscience</a>, pleasure has often been linked to the reward system, particularly with regard to learning processes. <a href="https://www.cell.com/current-biology/pdf/S0960-9822(14)01207-X.pdf">Studies</a> have shown that there are particular dopaminergic neurons that react to prediction error. Among other functions, this process enables us to learn about and predict the world around us. It is not yet clear whether pleasure drives learning or vice versa, but the two processes are undoubtedly connected. This also applies to music.</p> <p>When we listen to music, the greatest amount of pleasure stems from events predicted with only a moderate level of accuracy. In other words, overly simple and predictable events – or, indeed, overly complex ones – do not necessarily induce new learning and thus generate only a small amount of pleasure. Most pleasure comes from the events falling in between – those that are complex enough to arouse interest but consistent enough with our predictions to form a pattern.</p> <h2>Predictions dependent on our culture</h2> <p>Nevertheless, our prediction of musical events remains inexorably bound to our musical upbringing. To explore this phenomenon, a group of researchers met with the Sámi people, who inhabit the region stretching between the northernmost reaches of Sweden and the Kola Peninsula in Russia. Their traditional singing, known as yoik, differs vastly from Western tonal music due to limited exposure to Western culture.</p> <p>For a <a href="http://users.jyu.fi/%7Eptoiviai/pdf/Cognition.Yoiks.pdf">study</a> published in 2000, musicians from Sámi regions, Finland and the rest of Europe (the latter coming from various countries unfamiliar with yoik singing) were asked to listen to excerpts of yoiks that they had never heard before. They were then asked to sing the next note in the song, which had been intentionally left out. Interestingly, the spread of data varied greatly between groups; not all participants gave the same response, but certain notes were more prevalent than others within each group. Those who most accurately predicted the next note in the song were the Sámi musicians, followed by the Finnish musicians, who had had more exposure to Sámi music than those from elsewhere in Europe.</p> <h2>Learning new cultures through passive exposure</h2> <p>This brings us to the question of how we learn about cultures, a process known as enculturation. For example, <a href="https://www.musicnotes.com/now/tips/a-complete-guide-to-time-signatures-in-music/">musical time</a> can be divided in different ways. Western musical traditions generally use <a href="https://www.youtube.com/watch?v=e-CEd6xrRQc">four-time signatures</a> (as often heard in classic rock ‘n’ roll) or <a href="https://www.youtube.com/watch?v=-tn2S3kJlyU">three-time signatures</a> (as heard in waltzes). However, other cultures use what Western musical theory calls an asymmetrical meter. Balkan music, for instance, is known for asymmetrical meters like <a href="https://www.youtube.com/watch?v=b65FN-X3OkA">nine-time</a> or <a href="https://www.youtube.com/watch?v=EhVzrqvAsZI">seven-time signatures</a>.</p> <p>To explore these differences, a <a href="https://journals.sagepub.com/doi/full/10.1111/j.0956-7976.2005.00779.x">2005 study</a> looked at folk melodies with either symmetrical or asymmetrical meters. In each one, beats were added or removed at a specific moment – something referred to as an “accident” – and then participants of various ages listened to them. Regardless of whether the piece had a symmetrical or asymmetrical meter, infants aged six months or less listened for the same amount of time. However, 12-month-olds spent considerably more time watching the screen when the “accidents” were introduced into the symmetrical meters compared to the asymmetrical ones. We could infer from this that the subjects were more surprised by an accident in a symmetrical meter because they interpreted it as a disruption to a familiar pattern.</p> <p>To test this hypothesis, the researchers had a CD of Balkan music (with asymmetrical metres) played to the infants in their homes. The experiment was repeated after one week of listening, and the infants spent an equal amount of time watching the screen when the accidents were introduced, regardless of whether the meter was symmetrical or asymmetrical. This means that through passive listening to the Balkan music, they were able to build an internal representation of the musical metric, which allowed them to predict the pattern and detect accidents in both meter types. </p> <p>A <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2927013/pdf/nihms225442.pdf">2010 study</a> found a strikingly similar effect among adults – in this case, not for rhythm but for pitch. These experiments show that passive exposure to music can help us learn the specific musical patterns of a given culture – formally known as the process of enculturation.</p> <p>Throughout this article, we have seen how passive music listening can change the way we predict musical patterns when presented with a new piece. We have also looked at the myriad ways in which listeners predict such patterns, depending on their culture and how it distorts perception by making them feel pleasure and emotions differently. While more research is needed, these studies have opened new avenues toward understanding why there is such diversity in our music tastes. What we know for now is that our musical culture (that is, the music we have listened to throughout life) warps our perception and causes our preference for certain pieces over others, whether by similarity or by contrast to pieces that we have already heard.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/why-certain-types-of-music-make-our-brains-sing-and-others-dont-194100" target="_blank" rel="noopener">The Conversation</a>. </em></p>

The 10 “types” of grandparents

<p>In his book, <em>The Grandparent Guide: The Definitive Guide to Coping with the Challenges of Modern Grandparenting</em>, Dr. Arthur Kornhaber, a psychiatrist and founder of a non-profit organisation that promotes the importance of grandparenting identified 10 special roles grandparents play in the lives of grandchildren, all showing the profound impact grandparents can have on children’s lives. Which role, or roles, do you most identify with?</p> <p><strong>Ancestor –</strong> “You function as an ambassador to the past, a powerful figure in the present, and a role model for the future.”</p> <p><strong>Buddy –</strong> “You’re a pal, secret confidante, and at times, even a light-hearted conspirator.”</p> <p><strong>Hero –</strong> “The fact that you have lived in times and places so far removed from your grandchild’s everyday experiences imbues you with heroic qualities.”</p> <p><strong>Historian –</strong> “Sharing your own life experiences as well as those of your ancestors will give your grandchild a sense of continuity and belonging.”</p> <p><strong>Mentor –</strong> “You are a cheerleader firing her imagination, inspiring her dreams, nurturing her spirit, and encouraging her intellectual growth while giving her a sense of self-worth.”</p> <p><strong>Role model –</strong> “Your actions show your children and grandchildren how they should behave as grandparents of the future.”</p> <p><strong>Spiritual guide –</strong> “Acting as a spiritual guide involves teaching your grandchild to harvest such fruits of the spirit as love, tolerance, compassion, reverence, joy, peace, gentleness, faith, and kindness.”</p> <p><strong>Teacher –</strong> “As a grandparent, you have the right and the responsibility to run your own classroom about life, to develop your own curriculum, and to pass on your wisdom, knowledge, and life experience.”</p> <p><strong>Student –</strong> “Just as you teach and inspire your grandchild with your knowledge, she can teach and inspire you with her knowledge of contemporary times across generations and motivate you to jumpstart your capacity to grow and change.”</p> <p><strong>Wizard –</strong> “Activate your own wizardry and be your grandchild’s companion in the preternatural world of make-believe and illusion, of dreams and surprises. Fly together on the wings of fancy and enjoy the flight!”</p> <p><em>Image: Getty Images</em></p>

Is just 4.5 kg of weight loss really going to help stop type 2 diabetes?

<p>A new study has found that losing just 4.5 kg of weight could be the difference between getting type 2 diabetes and not.</p> <p>That’s the headline on some of the publicity surrounding the research, except like all these studies, it’s significantly more complicated than that. So, let’s talk about it.</p> <p>The study looked at around 100,000 nurses and other health professionals from a few different US cohort studies that started in the late 1980s.</p> <p>The team looked at up to 10 years of weight changes and tracked the participants for 24 years to see if they developed type 2 diabetes.</p> <p>They also looked at the way that those who lost more than 4.5 kg, dieted. They split them into seven categories – low-calorie diet; exercise; low-calorie diet plus exercise; fasting; commercial weight loss program; diet pills; and a combination of fasting, commercial and diet pills.</p> <p>When the team looked at the original results, they found something surprising: In the overall population, those who lost more than 4.5 kilograms had a higher risk of being diagnosed with type 2 diabetes than those that didn’t diet or try and lose weight.</p> <p>This was particularly striking for those that lost the weight due to limiting calories, diet pills, fasting, or weight loss programs.</p> <p>The researchers then split the data into BMI categories – those who were ‘normal’ weight or underweight, those who were overweight and those who were obese.</p> <p>The findings of a higher risk of type 2 diabetes after trying to lose weight broadly held in both the ‘underweight’ and ‘normal’ as well as the ‘overweight’ categories.</p> <p>“We were a bit surprised when we first saw the positive associations of weight loss attempts with faster weight gain and higher type 2 diabetes risk among lean individuals,” says Qi Sun, a nutrition researcher at the TH Chan Harvard School of Public Health.</p> <p>As you can see in this figure below, the risk of type 2 diabetes only reduced a little – significantly less than the increased risk of type 2 diabetes if you lost over 4.5 kilograms while at a normal BMI.</p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/10/figures.jpg" alt="" width="1280" height="720" /></p> <p>As noted in the paper, the vast majority of people try and diet at some point or another – in 2013 to 2016 almost half of US adults reported trying to lose weight.</p> <p>But almost everyone either doesn’t succeed or puts all the weight back on, normally within a few months.</p> <p>This study backs that up. After 10 years, those who tried to lose weight (known as the weight loss strategies group) gained more weight than those that hadn’t.</p> <p>“Participants who lost 4.5+ kg were likely to gain more weight and have higher risk of type 2 diabetes than those who did not attempt to lose weight,” the team writes in their paper.</p> <p>“By 10 years of follow-up, all weight loss strategy groups were associated with more weight gain than the reference group (ranging from 1.7% for exercise to 6.6% for fasting, commercial weight loss program and pills).”</p> <p>It’s important to note here that exercise and eating well is not bad for you. Exercise has been shown time and time again to help us live longer, and eating more fruits and vegetables and less processed food is better for us.</p> <p>However, this study is a good reminder that just losing weight – particularly in ways like weight loss pills, calorie restriction and weight loss programs are not a silver bullet for keeping us healthy.</p> <p>In fact, depending on who you are, it seems it might make it worse.</p> <p>The conclusion from the study is worth reading in full:</p> <p>In conclusion, in individuals with obesity, losing 4.5+ kg of body weight intentionally was associated with less weight gain and lower T2D risk, regardless of the methods used to achieve the weight loss. However, for individuals who were lean, losing 4.5+ kg was not associated with these health benefits. Of all WLSs, exercise was optimal for long-term weight control and T2D prevention. Our data support current guidelines for body weight management, such as that issued by the Obesity Society, which recommend a weight loss of 5% to 10% of baseline weight for individuals who are overweight or obese and exercise of 200 to 300 minutes per week to maintain the weight loss.</p> <p><strong>This article originally appeared on <a href="https://cosmosmagazine.com/health/diabetes-type-2-weight-loss-4-5-diet-pills-exercise/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Jacinta Bowler.</strong></p> <p><em>Image: Shutterstock</em></p>

The 5 worst types of people on cruises

<p>There is so much for you to enjoy on a cruise – state of the art facilities, sunshine, an escape from normal life and the food.</p> <p>However, just like anywhere else you go in the world, you can never anticipate the type of people you will be surrounded by when you cruise.</p> <p>To save you wasting any unnecessary time and energy, here are the <a href="../Find%20out%20about%20the%20five%20types%20of%20people%20you%20may%20encounter%20on%20a%20cruise." target="_blank" rel="noopener"><span style="text-decoration: underline;"><strong>types of people you need to be wary</strong></span></a> of during your cruise.</p> <p><strong>1. The deckchair hog</strong></p> <p>Despite there being a limited amount of deckchairs on board, some cruisers think it is acceptable to lay their sunscreen, towels, hats and books over a deckchair in a bid to communicate that it is “taken".  Although it is common courtesy to remove your belongings if you won’t be needing the chair, unfortunately this seldom happens. If you are looking to enjoy lying by the pool, be ready to wake up early to get yourself a deckchair.</p> <p><strong>2. The buffet over-eater</strong></p> <p>These travellers think it is fine to pile up their plates with all the best food, leaving everyone else waiting for the mains to be restocked. After their meal, they are back again for as many more rounds as their stomachs can handle. There is nothing wrong with eating big portions to satisfy your hunger, however, often these people are only taking excessive amounts of food to get their money’s worth.</p> <p><strong>3. The cruise “expert”</strong></p> <p>Sometimes you can find seasoned cruisers who will share great hints about the ship and activities worth trying. Other times, you will meet a know-it-all who will criticise various elements of the cruise due to their “experience”. It is better to be surrounded by the optimistic when trying to enjoy a relaxing cruise getaway.</p> <p><strong>4. The spa dominator</strong></p> <p>Although there is only a select amount of space to be enjoyed in the spa, some travellers will go there day in and day out, not caring about whether anyone else wants to use it. It is even worse when a whole group of people are committed to using the spa for most of the trip, ignoring all their fellow cruisers who are patiently waiting to use it.</p> <p><strong>5. The entitled cruiser</strong></p> <p>You will see this kind of traveller clicking their fingers at staff or making another complaint about something that wasn’t up to their standard. If things go wrong it is definitely necessary to get staff to fix the issue, however, no matter the situation you can still be kind.</p> <p>What kind of people have you noticed on cruises? Let us know in the comments below. </p> <p><em>Image: Getty</em></p>

10 tips to find the perfect style for your body type

<p>Whether we are 30 or 60, we all want to look like the best version of ourselves by wearing clothing that accentuates our silhouette in a positive manner. Fashion should be fun and a thing which boosts our confidence, not something that causes us stress and hits us with a dose of low self-esteem.</p> <p>No matter what your body shape is, you can always take your everyday style to an elegant and sophisticated state, that is always timeless but also modern. Here are 10 tips to help you find the perfect style for your body shape.</p> <p><strong>Hourglass</strong></p> <p>If your bust and hips are full and your waist is smaller, then you have an hourglass figure. The best way to flatter this body shape to your advantage is by wearing fit and flare dresses which will accentuate your tiny waist and leave room for the fuller areas of your body. Other design silhouettes like peplum tops or body hugging pieces will also help to flatter your body shape.</p> <p><strong>Apple shape</strong></p> <p>When your silhouette is fuller throughout, just like the shape of an apple, but your legs are slim, then you need tunic tops to give the upper part of your bodya flowy shape and sheath dresses (which are very much like a T shirt in design but longer) to straighten your apple shaped body. To balance the bottom area of your body, you can wear slim pants, preferably tailored pieces to accentuate the tiniest area on your body.</p> <p><strong>Heavy bust</strong></p> <p>When your bust area is quite large and the rest of your body is smaller, then you might want to minimise this feature. One way of balancing your heavy bust and make it appear smaller than it is, is by wearing V-neck tops and knitwear, as well as buttoned up shirts with the top three buttons left open. You can also use the timeless design of a wrap dress with this kind of body shape.</p> <p><strong>Pear shape</strong></p> <p>One of the most common body shapes out there, a pear shaped body, with a tiny top part and a larger bottom area needs boxy shaped tops to make the bust area look bigger and A-line dresses to hide the wider hips and thighs. Bootleg pants can also help to balance the wide hips by widening the area around your ankles.</p> <p><strong>Rectangle shape</strong></p> <p>When your body is quite straight, with relatively no curves, then you have a rectangle shape and you need clothing to help you create the idea of curves. High neck tops like polo necks and collared blouses, as well as statement jewelry to add more volume to your neck area are all ways you can use clothing to add the suggestion of curves on your body.</p> <p><strong>Carrot shape</strong></p> <p>A relatively unknown definition for a body shape, a carrot shape is when you have a broad shoulder area but the rest of your silhouette is quite tiny. There are two ways you can work this body shape. You can either use your bottom area to create volume there by wearing skirts and trousers with pleats or you can accentuate the shoulder area with embellishment and keep the rest of your body tiny by wearing body hugging pieces.</p> <p><strong>Accessories</strong></p> <p>Choosing accessories that are not unproportioned to your body is how you will continue to flatter your body shape, so if you have a full bust, don’t wear a dainty necklace that will appear very small in that area.</p> <p><strong>Use colour</strong></p> <p>We tend to steer clear of color when we are older but using color to highlight the best areas of your body is another way of playing up your shape.</p> <p><strong>Be wary of prints</strong></p> <p>While prints are great to bring that bold touch to your everyday look, try to avoid wearing prints on those areas of your body which you want to minimize.</p> <p><strong>Shoes always help</strong></p> <p>You may not like wearing heels as much as you did in earlier decades but even a pair of comfortable shoes with a small heel can really help to elongate your body and help to make you look slimmer.</p> <p><em>Image credits: Getty Images</em></p>

Every type of wedding guest attire, explained

<p><strong>Deciphering wedding dress codes</strong></p> <p>Even if you’re well versed in wedding traditions, there’s a good chance that one bit of wedding etiquette gives you pause: exactly how to decipher wedding dress codes. After all, is it really a big deal if you wear black-tie clothing to a white-tie wedding? It’s all formal…but is ‘formal’ a different category altogether? And on a completely different note, how casual is casual? It’s enough to give anyone a headache, but don’t worry – this primer on proper wedding guest attire will tell you everything you need to know.</p> <p>The first thing you should do to figure things out? Check your invitation. It will often tell you what type of wedding you’ll be attending. If not, or if the language is vague, check the couple’s website. While you can always fall back on classic dresses, some weddings do have strict dress codes that you’ll definitely want to follow.</p> <p><strong>What is the normal dress code for a wedding?</strong></p> <p>There isn’t one official dress code for every wedding, but you should always keep the following advice in mind when figuring out what to wear: “I want to look nice but not take away focus from the couple I’m celebrating,” says bridal stylist, Kennedy Bingham. That means sticking to styles and colours that aren’t too bold or too sexy – and certainly never wearing white.</p> <p>Beyond that, if the invitation doesn’t specify a dress code, you should take into consideration the time of day the wedding is being held, along with the venue. “I think the later [in the day] the wedding is, the more formally it should be treated,” says Bingham. “A nice summer sundress might be fine for a breakfast wedding, but it would look out of place at a dinner party.” That line of thinking follows logically to the venue. For example, if a wedding is being held outdoors in a park or beach, you might want to opt for something a little more casual. While we’re on the subject, make sure you’re wearing comfortable wedding shoes that work for the setting.</p> <p><strong>What colours are not appropriate for a wedding?</strong></p> <p>The days of not being allowed to wear black to a wedding are over. In fact, bridal boutique manager, Ashley Grape, recommends wearing a classic little black dress (long or short) to black-tie weddings. However, unless specifically requested by the bride, there are a few colours that should never be worn by a wedding guest: white, cream, off-white, or ivory. You also shouldn’t wear a dress that looks even vaguely bridal. Other no-nos? Neon shades, bright red from head to toe, and anything overly sequined or bedazzled.</p> <p><strong>White tie</strong></p> <p>White-tie weddings are the most formal type of weddings, and they have a strict dress code. Partially due to their high costs, white-tie weddings tend to be observed by royal families and members of high society. The name is derived from the man’s tuxedo, which consists of a black tail coat (the back of the coat – that is, the ‘tails’ – hang below a man’s knees) worn over a white tuxedo shirt that has a pointed wing collar, a white pique waistcoat, white bow tie, matching black trousers, and either black patent leather opera pumps or black patent lace-up oxfords. The perfect accessories for a man’s white-tie tuxedo are cuff links and a good watch.</p> <p>And women get to dress like princesses for the night. “Women can wear a grand ball gown with rich jewels,” states Deborah Van Cleve, owner of Van Cleve Bridal. Accessory options include full-length white gloves, jewelled clutches, and, if married, a tiara. “If you are lucky enough to be invited to one, don’t let the rules intimidate you,” says Van Cleve. “Dress for the occasion, and revel in the Britishness of it all.”</p> <p>Most white-tie weddings are adult-only affairs. If a teen makes the guest list, the dress code is the same as it is for the adult guests.</p> <p><strong>Black tie</strong></p> <p>One step down from white-tie weddings, black-tie weddings also require that all male guests wear a tuxedo, but men have some sartorial options within that category. “While black tuxedos are a mainstay for men, there are also deep navy tuxedos and lush velvet jackets for the winter months,” says Linda Della Rocco, a tuxedo and custom suiting specialist, saying, “I think a fun colour could be fine for a black-tie wedding, as long as it adheres to the traditional tux cuts and elements.” If there’s any doubt, though, check with the couple.</p> <p>For women, fancy dresses are the way to go for this type of wedding guest attire. If you have only one black-tie wedding to attend this season, invest in a sleekly tailored formal gown in a seasonal colour: jewel tones for fall and winter, and paler hues for spring and summer. “If it’s a summer full of weddings, try investing in one or two full-length skirts and coordinating tops,” suggests Grape. By mixing and matching formal separates, it will appear as if the guest has a closet full of gowns instead of four different pieces.</p> <p>When it comes to choosing jewellery and accessories for tuxedos and gowns, follow the protocol for white-tie weddings. Men’s tuxedo shirts should have cuff links, and men’s jewellery should be minimal – a wedding band or signet ring and a watch. Women can try pearl jewellery for a daytime wedding, and semiprecious jewellery for an evening event. Skip the tiara for a black-tie wedding…unless you’re the bride.</p> <p>Teens should follow the adult guests’ dress code. As for tweens and children, girls should opt for knee-length party dresses, and if the boys can tolerate it, tuxedos. If they’re wigglers, a boy’s formal suit is completely acceptable.</p> <p><strong>Casual</strong></p> <p>Confused as to how casual you should go when the wedding calls for casual attire? You’re not alone. “It’s one of the hardest [weddings] to dress for,” says Bingham. Still, leave the jeans at home, she says, no matter what. “[If it’s a] backyard wedding, I’d dress the way I would for a birthday brunch – a nice dress, possibly a maxi dress, and accessories. For guys, a suit with no tie, or khakis instead of dress pants.” Both men and women can accessorise with a hat, especially if it’s an outdoor wedding. Guys can try a straw boater, pork pie, or fedora, and women can opt for a casual fascinator or full-brimmed straw hat.</p> <p>The dress code for teens would be the same as for any quasi-formal event: a button-down shirt and khakis for boys, and either a knee- or ankle-length dress for girls, or a pair of dressy trousers with a pretty top. For tweens and younger kids, unfussy birthday-style dresses, pants, and button-up shirts fit the bill.</p> <p><strong>Cocktail</strong></p> <p>Cocktail attire is the marriage (so to speak) of formal and casual wedding guest attire. Women can opt for a cocktail dress that hits at the knee or below, or a dressy beaded suit dress. One classic option for a cocktail wedding is the classic little black dress, paired with either a diamond or pearl necklace, and black pumps or black dressy heeled sandals. Men can wear a suit and tie.</p> <p>For teens and children, girls can go with a classic party dress or dressy trousers and a shirt, while boys should wear a suit. These are good guidelines for children attending other types of formal events as well.</p> <p><strong>Formal</strong></p> <p>Formal and black-tie weddings are very similar. Sartorially speaking, a formal wedding is wedged in between cocktail and black tie. What to wear? For men, it’s a tuxedo or dark suit. If they’re feeling daring, and they’ve checked in with the bride, they may wear a brocade or print tuxedo. Women, on the other hand, have a plethora of dress choices that include full-length dresses, cocktail dresses and suits, beaded pantsuits, jumpsuits, or even gowns. Children should follow the dress code for a cocktail wedding – essentially, party dresses and suits.</p> <p><strong>Semiformal</strong></p> <p>OK, last one! Wedding guest attire for a semiformal wedding is less formal than a formal wedding…but dressier than a company dinner. Women can wear anything from a floor-length dress to a beaded cocktail suit. For men, a dark suit is the way to go. If a semiformal wedding is any time before cocktail hour (aka 5pm), women’s dresses should have less (if any) beaded embellishments. Footwear should suit the location, and jewellery can range from pearls to gold and semiprecious stones. Save the statement jewellery for night-time events.</p> <p>If teens and children are invited to a semiformal wedding, they should follow the dress code for a cocktail wedding.</p> <p><strong>Quick tips when trying on your outfit</strong></p> <p>Now that you’ve found the perfect wedding guest attire for your event, you’re ready to go. Well, almost. When your delivery arrives, don’t just look in the mirror to see how it looks on you. Take it for a walk – as in, really walk around in it, and then bend, sit, raise your hands, and even dance a little. By moving around, you’ll see how the outfit moves when you do and, most important, how comfortable you are in it.</p> <p>If you’re also buying new shoes for a wedding, make sure to break them in well before the event. After all, fabulous shoes don’t just look great – they feel great when you’re on your feet all day. And blisters are the last thing you want to deal with after (or, worse, during) a wedding.</p> <p>And finally, because the weather can change over the course of a day, bring a lightweight wrap with you. Depending on the season and event, go with cashmere, wool, or silk. A fancy spring jacket can also work over certain ensembles for in-transit moments.</p> <p><em><span id="docs-internal-guid-74139b16-7fff-1291-0ee3-8ada9a4280e6">Written by PJ Gach.

New type of gel helps the medicine go down

<p class="spai-bg-prepared">Swallowing tablets can be a challenge for most children and some adults, but scientists have come to the rescue with a new drug-delivering oleogel that can make it easier to consume a variety of medicines.</p> <p class="spai-bg-prepared">According to a <a class="spai-bg-prepared" href="https://www.science.org/doi/10.1126/sciadv.abm8478" target="_blank" rel="noreferrer noopener">new study</a>, the gels are made from plant-based oils and can be prepared in a variety of textures – from a thickened drink to a gel with yogurt-like consistency. This could help adults who have difficulty swallowing pills, such as older people or those who have suffered a stroke.</p> <p class="spai-bg-prepared">The gels have also been designed to remain stable at 40°C for two weeks, and even up to 60°C for one week. This could make them especially helpful for children in developing nations, where the gels might be transported in vehicles without refrigeration. </p> <p class="spai-bg-prepared">“Given the simplicity of the system and its low cost, it could have a tremendous impact on making it easier for patients to take medications,” says senior author Giovanni Traverso, assistant professor of mechanical engineering at Massachusetts Institute of Technology (MIT) and a gastroenterologist at Brigham and Women’s Hospital, US.</p> <p class="spai-bg-prepared">Existing strategies for people unable to swallow pills have relied on dissolving drugs in water, but this requires a water-soluble medicine, as well as access to clean water and refrigeration. It can also be difficult to achieve the right dosage for children if the pills used are meant for adults.</p> <p class="spai-bg-prepared">To avoid these issues, the interdisciplinary research team focused on the potential of oil-based gels, also known as oleogels, for drug delivery.</p> <p class="spai-bg-prepared">The researchers explored several different types of plant-derived oils, including sesame, cottonseed and flaxseed oil. By combining these oils with edible gelling ingredients – such as beeswax and rice bran wax – they found they could control the texture depending on the type of oil and gelling agent, and their concentrations.</p> <div class="newsletter-box spai-bg-prepared"> <div id="wpcf7-f6-p193139-o1" class="wpcf7 spai-bg-prepared" dir="ltr" lang="en-US" role="form"> </div> </div> <p class="spai-bg-prepared">To identify the most palatable oleogels, the researchers worked with a consulting firm specialising in consumer sensory experiences to narrow down the oleogels to those made from oils with a neutral or slightly nutty flavour.</p> <p class="spai-bg-prepared">“That approach gave us the capacity to deliver very hydrophobic drugs that cannot be delivered through water-based systems,” says lead author Ameya Kirtane, former MIT postdoctoral researcher and current instructor in medicine at Brigham and Women’s Hospital. “It also allowed us to make these formulations with a really wide range of textures.”</p> <p class="spai-bg-prepared">They then tested delivering three oil-soluble (hydrophobic) drugs from the World Health Organization’s (<a class="spai-bg-prepared" href="https://www.who.int/" target="_blank" rel="noreferrer noopener">WHO</a>) list of <a class="spai-bg-prepared" href="https://www.who.int/publications/i/item/WHO-MHP-HPS-EML-2021.03" target="_blank" rel="noreferrer noopener">essential medicines for children</a>: praziquantel, used to treat parasitic infections; lumefantrine, used to treat malaria; and azithromycin, used to treat bacterial infections.</p> <p class="spai-bg-prepared">The tests showed that in pigs the oleogels were able to deliver doses of these medicines equal to or greater than the amounts absorbed from tablets, and that a water-soluble <a class="spai-bg-prepared" href="https://cosmosmagazine.com/health/medicine/antibiotic-resistance-millions-years/" target="_blank" rel="noreferrer noopener">antibiotic</a> (moxifloxacin hydrochloride) could also be successfully delivered.</p> <p class="spai-bg-prepared">“Based on that list, infectious diseases really stood out in terms of what a country needs to protect its children,” Kirtane says. “A lot of the work that we did in this study was focused on infectious-disease medications, but from a formulation standpoint, it doesn’t matter what drug we put into these systems.”</p> <p class="spai-bg-prepared">A phase I clinical trial of the oleogel formulation of azithromycin should be underway within the next few months.</p> <p><img id="cosmos-post-tracker" class="spai-bg-prepared" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=193139&title=New+type+of+gel+helps+the+medicine+go+down" width="1" height="1" /></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/health/oleogels-alternative-medicine-delivery/" target="_blank" rel="noopener">This article</a> was originally published on <a href="https://cosmosmagazine.com" target="_blank" rel="noopener">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/imma-perfetto" target="_blank" rel="noopener">Imma Perfetto</a>.

Type of person who struggles with the idea of terminal illness

<p dir="ltr">People who tend to look after themselves by working out and eating healthy foods are more likely to struggle with the idea of death and the process of dying. </p> <p dir="ltr">Palliative care nurse Maryan Bova has helped people with dying for 25 years and said some people accept their terminal diagnosis while others struggle to come to terms with it. </p> <p dir="ltr">She revealed that those who lived a healthy lifestyle were those who felt more ripped off when they are given the awful diagnosis. </p> <p dir="ltr">“They're the ones that have looked after themselves their whole life, for example the yoga teacher who runs retreats and has probably never eaten anything that wasn't organic and green in their life,” she told Mamamia. </p> <p dir="ltr">“And yet they've been smacked down with a horrible diagnosis. It can feel like a slap in the face.”</p> <p dir="ltr">Maryan confessed that the job can be emotionally draining as some experiences stick with her, especially when she was in the same position. </p> <p dir="ltr">Her mother Helen was diagnosed with brain cancer and Maryan did what she did best - but this time it was someone close to her. </p> <p dir="ltr">"I knew what it would all end up looking like, but I also knew how to orchestrate the help that was needed for her to die at home in a space she was comfortable in,” she said.</p> <p dir="ltr">“It was a gift to have that time to talk openly, have important conversations and bond as a family. It was like mum became childlike again, a full-circle moment.”</p> <p dir="ltr">Maryan stressed that it was important to look at how people with a terminal diagnosis are treated in the last moments of their life. </p> <p dir="ltr"><em>Images: Facebook/Shutterstock</em></p>

Plant based diets could prevent type 2 diabetes

<p>Eating a diet high in plant foods with little or no red meat has been linked to a lower risk of type 2 diabetes in the most comprehensive scrutiny of this connection so far.</p> <p>This protective effect is even stronger for diets high in healthier plant foods such as fruits, vegetables, whole grains, legumes and nuts.</p> <p>Diabetes has been called “the fastest growing health crisis of our time”. At the same time, plant-based diets are gaining popularity.</p> <p><span style="font-family: inherit;">Therefore, the researchers thought it was important to quantify their link with diabetes risk, says first author Frank Qian from the Harvard TH Chan School of Public Health, US – especially given the large variation in these diets. </span></p> <p><span style="font-family: inherit;">The analysis, </span>published<span style="font-family: inherit;"> in the </span>Journal of the American Medical Association<span style="font-family: inherit;">, included nine studies with more than 300,000 participants – of whom 23,544 had type 2 diabetes – over two to 28 years of follow-up. </span></p> <p><span style="font-family: inherit;">In the primary evaluation, Qian and co-authors focussed on an overall higher intake of plant-based foods along with little or no animal-based foods. Therefore, this included vegetarian or vegan dietary patterns.</span></p> <p>They found that people with the highest adherence to predominantly plant-based diets had a 23% reduced risk of type 2 diabetes compared to those with the lowest consumption of plant foods.</p> <p>But these dietary patterns didn’t exclude plant-derived foods that have been linked to higher diabetes risk, such as sugar and refined carbohydrates.</p> <p><span style="font-family: inherit;">When narrowing the analysis to four studies that defined a plant-based diet as the healthy whole food options, they found a 30% lower risk of type 2 diabetes.</span></p> <p>While it must be noted that the studies are observational, most, if not all, adjusted for well-known risk factors, including body mass index (BMI), gender, smoking status and family history of diabetes, among other potentially confounding variables.</p> <p>Several factors could explain the associations, the authors say.</p> <p>Plant-based diets typically include healthy plant foods packed with nutrients, polyphenols and fibre, which can improve insulin sensitivity, lower blood pressure, reduce inflammation and help maintain a healthy weight.</p> <p><span style="font-family: inherit;">All of these can lower the risk of type 2 diabetes. Conversely, eating red and processed meat has been linked to higher risk.</span></p> <p><span style="font-family: inherit;">Because the studies controlled for BMI, and excess weight and type 2 diabetes are a deadly duo, the authors suggest the associations they found could underestimate the actual degree of protection conferred by the diets.</span></p> <p><span style="font-family: inherit;">“Overall,” says senior author Qi Sun, “these data highlight the importance of adhering to plant-based diets to achieve or maintain good health.” </span></p> <!-- Start of tracking content syndication.
