Jack Black cancels Tenacious D tour after on-stage Trump comment

<p>Jack Black has cancelled the rest of Tenacious D's Australia and New Zealand tour after his bandmate Kyle Gass’s on-stage joke about the attempted assassination of Donald Trump was widely condemned. </p> <p>Gass was celebrating his 64th birthday on stage at Sydney’s International Convention Centre on Sunday night, just hours after Trump was fired upon at a rally Pennsylvania, when Black presented him with a cake and asked for his birthday wish. </p> <p>“Don’t miss Trump next time,” Gass replied. </p> <p>The moment was captured and posted to TikTok where it quickly went viral, even attracting attention from radio shock jock <a href="https://oversixty.com.au/entertainment/music/kyle-slaps-comedy-legends-with-lifetime-ban-for-twisted-trump-joke" target="_blank" rel="noopener">Kyle Sandilands</a>, who proposed Tenacious D receive a lifetime ban from touring in Australia.</p> <p>Since the moment garnered online attention, Kyle Gass has been dropped by his talent agency, Greene Talent, with rep Michael Greene telling <em><a href="https://www.tmz.com/2024/07/16/tenacious-d-kyle-gass-dropped-talent-agency-trump-shooting-comment/" target="_blank" rel="noopener" data-link-type="article-inline">TMZ</a></em> they have parted ways due to the incident.</p> <p>In the hours after the show, Jack Black took to Instagram where he shocked fans by announcing the rest of their tour would be cancelled, as the joke prompted a falling out between the two bandmates.</p> <p>“I was blindsided by what was said at the show on Sunday. I would never condone hate speech or encourage political violence in any form,” Black wrote in a statement.</p> <p>“After much reflection, I no longer feel it is appropriate to continue the Tenacious D tour, and all future creative plans are on hold. I am grateful to the fans for their support and understanding.”</p> <p>Gass has since apologised for the joke, saying, “The line I improvised onstage Sunday night in Sydney was highly inappropriate, dangerous and a terrible mistake."</p> <p>“I don’t condone violence of any kind, in any form, against anyone. What happened was a tragedy, and I’m incredibly sorry for my severe lack of judgement."</p> <p>“I profoundly apologise to those I’ve let down and truly regret any pain I’ve caused.”</p> <p><em>Image credits: Reynaud Julien/APS-Medias/ABACA/Shutterstock Editorial/TikTok</em></p>

Vitamin D supplements can keep bones strong – but they may also have other benefits to your health

<p><em><a href="https://theconversation.com/profiles/martin-hewison-1494746">Martin Hewison</a>, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</a></em></p> <p>Most of us don’t worry about getting vitamin D when the weather’s warm and the sun is shining. But as winter approaches, accompanied by overcast days and long nights, you may be wondering if it could be useful to take a vitamin D supplement – and what benefit it might have.</p> <p>During the summer, the best way to get vitamin D is by getting a bit of sunshine. Ultraviolet rays (specifically UVB, which have a shorter wavelength) interact with a form of cholesterol called <a href="https://www.ncbi.nlm.nih.gov/books/NBK278935/">7-dehydrocholesterol</a> in the skin, which is then converted into vitamin D.</p> <p>Because vitamin D production is dependent on UVB, this means our ability to make it <a href="https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/#:%7E:text=From%20about%20late%20March%2Fearly,enough%20vitamin%20D%20from%20sunlight.">declines in the winter months</a>. Vitamin D production also <a href="https://pubmed.ncbi.nlm.nih.gov/24494042/">depends on where you live</a>, with people living nearer to the equator making more vitamin D than those living nearer the poles.</p> <p>Vitamin D deficiency is a <a href="https://assets.publishing.service.gov.uk/media/5a804e36ed915d74e622dafa/SACN_Vitamin_D_and_Health_report.pdf">problem in the UK</a> during the winter months. This is due to its northerly position and cloudy weather, and lack of time spent outdoors.</p> <p>One study of over 440,000 people in the UK found that <a href="https://pubmed.ncbi.nlm.nih.gov/33309415/">18% were vitamin D deficient</a> during the winter months. Vitamin D deficiency was even higher in certain ethnic groups – with the data showing 57% of Asian participants and 38% of black participants were vitamin D deficient. This is because the melanin content of skin determines a person’s ability to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5946242/#:%7E:text=Skin%20pigmentation%2C%20i.e.%2C%20melanin%2C,%5B7%5D%20and%20more%20generally.">make UVB into vitamin D</a>.</p> <p>Given the prevalence of vitamin D deficiency in the UK, and the importance it has for our health, in 2016 the UK’s Science Advisory Council on Nutrition outlined recommendations for the <a href="https://www.gov.uk/government/publications/sacn-vitamin-d-and-health-report#:%7E:text=In%20a%20change%20to%20previous,aged%204%20years%20and%20older">amount of vitamin D</a> people should aim to get in the winter.</p> <p>They recommend people aim to get ten micrograms (or 400 IU – international units) of vitamin D per day. This would help people avoid severe deficiency. This can be achieved either by taking a supplement, or eating <a href="https://www.bhf.org.uk/informationsupport/heart-matters-magazine/nutrition/ask-the-expert/foods-high-in-vitamin-d">certain foods</a> that are rich in vitamin D – including fatty fish such as herring, mackerel and wild salmon. A 100 gram serving of fresh herring, for example, would have approximately five micrograms of vitamin D.</p> <p>The clearest benefit of taking a vitamin D supplement is for <a href="https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/">bone health</a>. In fact, vitamin D was <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3899558/">first discovered</a> 100 years ago because of its ability to prevent the disease rickets, which causes weak bones that bend.</p> <p>Although rickets <a href="https://www.nhs.uk/conditions/rickets-and-osteomalacia/#:%7E:text=The%20number%20of%20rickets%20cases,from%20sunlight%2C%20can%20develop%20rickets.">isn’t very common</a> in the UK today, it can still occur in children if they lack vitamin D. In adults, vitamin D deficiency can cause bone pain, tenderness and muscles weakness, as well as increased risk of osteomalacia – often called “soft bone disease” – which leads to weakening or softening bones.</p> <p>The reason a lack of vitamin D can have such an effect on bone health is due to the vitamin’s relationship with <a href="https://pubmed.ncbi.nlm.nih.gov/18844850/">calcium and phosphate</a>. Both of these minerals help keep our bones strong – but they require vitamin D in order to be able to reinforce and strengthen bones.</p> <h2>Other health benefits</h2> <p>In addition to its effects on the skeleton, a growing body of research is beginning to indicate that vitamin D supplements may have additional benefits to our health.</p> <p>For example, <a href="https://ar.iiarjournals.org/content/42/10/5009.long">research shows</a> there’s a link between vitamin D deficiency and increased risk of catching certain viral illnesses, including the <a href="https://pubmed.ncbi.nlm.nih.gov/19237723/">common cold</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7231123/">flu</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7385774/">COVID</a>.</p> <p>Similarly, several studies – <a href="https://pubmed.ncbi.nlm.nih.gov/32904944/">including my own</a> – have demonstrated in cell models that vitamin D promotes immunity against microbes, such as the bacteria which causes tuberculosis. This means vitamin D may potentially prevent some types of infections.</p> <p>Vitamin D may also dampen inflammatory immune responses, which could potentially protect against autoimmune diseases, such as <a href="https://pubmed.ncbi.nlm.nih.gov/29243029/">multiple sclerosis</a> and <a href="https://www.frontiersin.org/articles/10.3389/fmed.2020.596007/full">rheumatoid arthritis</a>.</p> <p>One 2022 trial, which looked at over 25,000 people over the age of 50, found taking a 2,000 IU (50 micrograms) vitamin D supplement each day was associated with an <a href="https://www.bmj.com/content/376/bmj-2021-066452">18% lower risk</a> of autoimmune disease – notably rheumatoid arthritis.</p> <p>Vitamin D supplements may also be linked with lower risk of cardiovascular disease. A <a href="https://www.bmj.com/content/381/bmj-2023-075230">major Australian study</a>, which looked at over 21,000 people aged 60-84, found that participants who took a 2,000 IU vitamin D supplement a day for five years had a lower risk of suffering a major cardiovascular event (such as stroke or heart attack) compared to those who didn’t take a supplement.</p> <p>It’s currently not known why vitamin D may have these benefits on these other areas of our health. It’s also worth noting that in many of these trials, very few of the participants were actually vitamin D deficient. While we might speculate the observed health benefits may be even greater in people with vitamin D deficiency, it will be important for future research to study these factors.</p> <p>While it’s too early to say whether vitamin D supplements have broad health benefits, it’s clear it’s beneficial for bone health. It may be worthwhile to take a supplement in the winter months, especially if you’re over 65, have darker skin or spent a lot of time indoors as these factors can put you at <a href="https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/expert-answers/vitamin-d-deficiency/faq-20058397#:%7E:text=However%2C%20some%20groups%20%E2%80%94%20particularly%20people,sun%20exposure%20or%20other%20factors.">increased risk of vitamin D deficiency</a>.</p> <p>The research also shows us that we should be rethinking vitamin D supplementation advice. While in the UK it’s recommended people get 400 IU of vitamin D a day, many trials have shown 2,000 IU a day is associated with health benefits.<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/219521/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/martin-hewison-1494746"><em>Martin Hewison</em></a><em>, Professor of Molecular Endocrinology, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</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.

Should I be getting my vitamin D levels checked?

<p><em><a href="https://theconversation.com/profiles/elina-hypponen-108811">Elina Hypponen</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Australia has seen a <a href="https://insightplus.mja.com.au/2023/29/gps-urged-not-to-routinely-test-children-for-vitamin-d/">surge in vitamin D testing</a> of children, with similar trends reported for adults around the <a href="https://pubmed.ncbi.nlm.nih.gov/29659534/">world</a>. GPs are now <a href="https://insightplus.mja.com.au/2023/29/gps-urged-not-to-routinely-test-children-for-vitamin-d/">being urged</a> not to test for vitamin D unnecessarily.</p> <p>So when is low vitamin D a potential concern? And when might you need to get your levels tested?</p> <h2>How much vitamin D do we need?</h2> <p>Vitamin D is not only a nutrient – when metabolised in the body it acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/29080638/">hormone</a>. We have receptors for this hormone all around our body and it helps regulate the metabolism of calcium and phosphorus.</p> <p>Vitamin D also has many other roles, including helping our immune defences and contributing to <a href="https://pubmed.ncbi.nlm.nih.gov/11295155/">DNA repair</a> and cell differentiation.</p> <p>We can thank the sun for most of our vitamin D. A chemical in our skin called 7-dehydrocholesterol is converted to vitamin D after contact with UVB radiation from the sun.</p> <p>While we get some vitamin D also <a href="https://pubmed.ncbi.nlm.nih.gov/35253289/">through our diet</a>, this makes a relatively small contribution. It’s difficult to get much more than one-third of our daily vitamin D requirement from diet without supplementation.</p> <p>Nutritional vitamin D status is <a href="https://en.wikipedia.org/wiki/Calcifediol">typically measured</a> via a blood test. This checks the calcidiol (calcifediol, 25-hydroxyvitamin D) concentrations, which reflect the average intakes from the sun and diet over the past three to four weeks.</p> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/22708765/">current recommendation</a> is that we should all aim to have at least 50nmol/L (20ng/mL) at the end of winter.</p> <p>However, one problem with vitamin D tests is that there is <a href="https://pubmed.ncbi.nlm.nih.gov/37182753/">variation</a> in measured concentrations between the laboratories and between the assays, and whether you’re deemed to have a deficiency can depend on the testing method used.</p> <p>Doctors do not always agree with what is deficiency. While very low concentrations are likely to prompt doctors to recommend a supplement (and, potentially, follow-up testing), some may consider even relatively high concentrations as inadequate.</p> <p>This is all understandable as research in this space is still evolving, and we know low concentrations do not always cause any symptoms.</p> <h2>Why avoid vitamin D deficiency?</h2> <p>Prolonged, severe vitamin D deficiency will lead to softening of bone tissue and cause diseases such as rickets (children) and osteomalacia (adults).</p> <p>However, avoiding low concentrations is likely to be good for <a href="https://pubmed.ncbi.nlm.nih.gov/37483080/">many aspects of health</a>, with consistent evidence suggesting benefits for <a href="https://www.bmj.com/content/356/bmj.i6583">infectious diseases</a> and autoimmune conditions such as multiple sclerosis.</p> <p>Randomised trials have also provided evidence for lower <a href="https://pubmed.ncbi.nlm.nih.gov/35676320/">cancer</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/24414552/">all cause mortality</a> by daily supplementation, although any benefit is likely to be restricted to those who otherwise have insufficient intakes.</p> <h2>Who is at risk of deficiency?</h2> <p>Most of us do not need tests to have a relatively good idea whether we might be at risk of a clinically important deficiency.</p> <p>If it’s not late winter, we spend regularly at least some time outside with skin exposed to the sun, and we do not belong to a specific high-risk group, it is unlikely that our <a href="https://pubmed.ncbi.nlm.nih.gov/22168576/">levels would be very low</a>.</p> <p>The two main reasons for vitamin D deficiency typically relate to:</p> <p><strong>1. not getting (enough) vitamin D through sun exposure.</strong> Deficiency risk <a href="https://www.healthdirect.gov.au/vitamin-d-deficiency">can be high</a> for anyone who is housebound, such as older or disabled people in residential care. The risk of deficiency increases if we always cover our skin carefully by <a href="https://pubmed.ncbi.nlm.nih.gov/19211395/">modest cultural dress,</a> and also <a href="https://pubmed.ncbi.nlm.nih.gov/6119494/">dark skin pigmentation</a> is known to reduce vitamin D synthesis.</p> <p><strong>2. having a chronic disease that alters your requirement.</strong> Medications such as anticonvulsants used to treat epilepsy, and conditions such as <a href="https://my.clevelandclinic.org/health/diseases/15050-vitamin-d-vitamin-d-deficiency">liver and kidney diseases</a> can interfere with vitamin D metabolism. Some <a href="https://my.clevelandclinic.org/health/diseases/15050-vitamin-d-vitamin-d-deficiency">digestive diseases</a> can reduce vitamin D absorption from your diet, while <a href="https://pubmed.ncbi.nlm.nih.gov/30020507">obesity</a> will increase your vitamin D requirement and make it more difficult to raise your blood levels.</p> <h2>Am I getting enough sun exposure?</h2> <p>In Australia, it is possible to get enough vitamin D from the sun <a href="https://healthybonesaustralia.org.au/your-bone-health/vitamin-d-bone-health">throughout the year</a>. This isn’t so for many people living in the northern hemisphere.</p> <p>For those who live in the top half of Australia – and for all of us during summer – we <a href="https://healthybonesaustralia.org.au/your-bone-health/vitamin-d-bone-health">only need</a> to have skin exposed to the sun a few minutes on most days.</p> <p>The body can only produce a certain amount of vitamin D at the time, so staying in the sun any longer than needed is not going to help increase your vitamin D levels, while it will increase your risk of skin cancer.</p> <p>During winter, catching enough sun can be difficult, especially if you spend your days confined indoors. Typically, the required exposure increases to two to three hours per week in winter. This is because sunlight exposure can only help produce vitamin D if the UVB rays reach us at the correct angle. So in winter we should regularly spend time outside in the middle of the day to get our dose of vitamin D.</p> <p>If you are concerned, you have very dark skin, or are otherwise in a high-risk group, you may want to talk to your GP.</p> <p>In any case, taking a modest daily dose of vitamin D (1,000-2,000 IU) during the darker winter months is unlikely to cause harm and it <a href="https://pubmed.ncbi.nlm.nih.gov/37483080/">may be beneficial</a>.</p> <h2>Why does excess vitamin D testing matter?</h2> <p>When not indicated, testing can cause unnecessary worry and promote a cascade of <a href="https://pubmed.ncbi.nlm.nih.gov/32675268/">laboratory, prescription and imaging services</a> that are of low value.</p> <p>Excessive testing is also a waste of health-care resources, with one <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.50619">single test</a> costing about the same as a years’ worth of vitamin D supplementation.</p> <p>Very often, we can make relatively small changes to our lifestyles to reduce the risks of vitamin D deficiency. <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/211268/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/elina-hypponen-108811">Elina Hypponen</a>, Professor of Nutritional and Genetic Epidemiology, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</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.

Natural ways to boost your vitamin D

<p>Known as the sunshine vitamin, maintaining the right level of vitamin D is essential to keep you healthy. Luckily there are a number of ways you can naturally boost your intake.</p> <p>Research now shows that apart from bone health, vitamin D is also linked to many other functions in the body, too. We’ve done the legwork for you. The sunshine vitamin can also be beneficial for cardiovascular health, rheumatoid arthritis, cancer, glucose intolerance, multiple sclerosis, type 1 and type 2 diabetes, depression and to protect against colds. Here are four ways you can ensure adequate intake – and naturally, too! But like most things in life, a combination of diet, supplements and environment is the key.</p> <p><strong>Sunlight</strong><br />The best source of vitamin D is UV-B radiation from the sun. Approximately five to 30 minutes of sun exposure while you’re not wearing sun screen (between 10am and 3pm), at least twice a week, will do the job. It is worth keeping in mind that UV radiation levels vary depending on things like, location, time of year and time of day, so make sure you wear sun protection when the UV Index is three or above. In some states, UV radiation is higher and sun protection is needed all year round at certain times of the day. The Cancer Council Australia say that for most people, adequate vitamin D levels are reached through regular daily activity and incidental exposure to the sun. To check UV levels and the times sun protection is required, look on the Bureau of Meteorology website at www.bom.gov.au – search for UV alert.</p> <p><strong>Diet</strong><br />There are many food options that you can incorporate into your diet to ensure you have healthy levels of the sunshine vitamin. Think fatty fish (sardines, herring, mackerel, tuna and salmon), canned tuna, milk that has been fortified with vitamin D, egg yolks and cereals that have been fortified with vitamin D.</p> <p><strong>Supplements</strong><br />From tablets and capsules to liquids, supplements are a convenient way to ensure you are getting enough vitamin D. The even better news is, there are some natural supplement options out there. Be careful, though, as too much can be toxic. Depending on your situation, daily dosages vary. The safest way to be sure on what’s best for you is to consult your doctor.</p> <p><strong>Cod liver oil</strong><br />If you’re not a fan of fatty fish, then you’ll be pleased to know that cod liver oil – which comes from the liver of the cod fish – is very rich in vitamins A and D. Women 60-plus should have around 700mcg per day and men 60-plus, 900mcg per day.</p> <p><em>Image: Shutterstock</em></p>

The benefits of vitamin D – from head to toe

<p><strong>The benefits of vitamin D</strong></p> <p>Is it the magic vitamin? Well, it might be close. Research in recent years has shown that vitamin D may be one of the most powerful supplements to boost your total wellness and even help promote longevity. For years, vitamin D was touted as an ace for stronger bones, shinier hair and as a potential mood-booster. But you might not be aware of the many benefits vitamin D can provide for your whole system.</p> <p><strong>Brain</strong></p> <p>When taken with fish oil, vitamin D is a powerful mood booster, according to a study published in the <em>FASEB </em>journal. The aptly named ‘sunshine vitamin’ improves mood and lowers depression by aiding the conversion of the essential amino acid tryptophan into serotonin – a brain chemical that regulates mood. But that’s not all! Vitamin D improves memory and cognitive functions in older women, according to a separate study published in <em>Journals of Gerontology A</em>. Meanwhile, previous research has found it may also have some protective effects against Alzheimer’s disease.</p> <p><strong>Eyes</strong></p> <p>Laugh lines aside, your eyes themselves undergo signs of ageing that can impair your vision. According to a study published in <em>Neurobiology of Ageing</em>, a daily dose of vitamin D reduced some of the effects of ageing on eyes, reduced inflammation and improved vision in mice. A second study found that it may also help prevent macular degeneration, a common eye disease that can lead to blindness if it goes untreated.</p> <p><strong>Ears</strong></p> <p>What causes vertigo, that disorienting sensation of dizziness and spinning? Vertigo may feel like your head is spinning, but the problem often stems from the structures in your inner ear that are responsible for balance. However, taking vitamin D and calcium twice a day may reduce vertigo and lower your chances of getting vertigo again, according to a study published in <em>Neurology</em>.</p> <p><strong>Teeth</strong></p> <p>Want stronger, whiter teeth and fewer cavities? Taking a daily vitamin D supplement may help, according to a meta-analysis published in <em>Nutrients</em>. Researchers analysed dozens of controlled studies with thousands of participants in several countries to find that that vitamin D was associated with a 50 per cent reduction in the incidence of tooth decay.</p> <p><strong>Gums</strong></p> <p>The same vitamin D supplement that strengthens your teeth can also help protect your gums from bacterial infections that lead to problems like gingivitis and periodontitis, according to the <em>Nutrients </em>study. Periodontitis, a potentially serious infection of the gum tissue, is a major cause of tooth loss and can also contribute to heart disease.</p> <p><strong>Heart</strong></p> <p>One of vitamin D’s most powerful roles is in the cardiovascular system, where there are 200 genes regulated by vitamin D. How does it work? Vitamin D may help stop cholesterol from clogging arteries, regulate blood pressure and improve the function of cells in the heart. Even better, it may also be able to help heal existing heart damage, according to research published in the <em>International Journal of Nanomedicine</em>.</p> <p><strong>Lungs</strong></p> <p>Asthma, chronic obstructive pulmonary disease (COPD), emphysema and chronic bronchitis affect many people. While it’s not a cure, vitamin D can reduce the number of lung disease flareups by 40 per cent, a study published in <em>The Lancet</em> concluded. The same may be true for asthma, according to a separate study published in <em>Cochrane Review</em>. Researchers found that people who took a daily dose of vitamin D in addition to their asthma medication reduced the number of severe asthma attacks they experienced.</p> <p><strong>Gut</strong></p> <p>People with metabolic syndrome – increased blood pressure, high blood sugar, excess body fat around the waist and abnormal cholesterol or triglyceride levels – are at a high risk of heart disease, stroke and type 2 diabetes. Exercise and a healthy diet are important practices to avoid or heal the syndrome, but research has suggested vitamin D may also help. In a study published in <em>Frontiers in Physiology</em>, vitamin D improved signs of metabolic syndrome by boosting healthy gut bacteria in mice.</p> <p><strong>Liver</strong></p> <p>Higher vitamin D levels are linked with lower levels of cancer in general, and less liver cancer specifically, according to a <em>BMJ </em>study. Researchers took samples from over 33,000 adult participants and found that higher levels of the nutrient were associated with a 20 per cent reduction in cancer and a 30-50 per cent reduction in liver cancer.</p> <p><strong>Reproductive system</strong></p> <p>Both men and women show reproductive and fertility benefits from vitamin D. Female participants who had a healthy vitamin D level early in pregnancy were more likely to have a baby with a healthy weight and head size in a study published in the <em>Journal of Clinical Endocrinology &amp; Metabolism</em>. Similarly, men with higher vitamin D levels had a better fertility potential, particularly through better sperm motility, say researchers in a separate study, published in<em> World Journal of Men’s Health</em>.</p> <p><strong>Bones</strong></p> <p>Think calcium is the best nutrient for bones? Think again. The positive effects of vitamin D on bone health are some of the most documented benefits of the nutrient. Vitamin D is essential for building and maintaining strong bones, while inadequate vitamin D can lead to osteoporosis, a brittle bone disease, according to the Mayo Clinic.</p> <p><strong>Knees</strong></p> <p>Your knees are one of the most-used joints in your body and often one of the first places to experience joint pain as you get older. Research has suggested the most common causes of joint pain are osteoarthritis from joint overuse or injury, and rheumatoid arthritis – an autoimmune disease that attacks joints. Vitamin D can help protect against both types of arthritis. People who maintained healthy vitamin D levels were less likely to get rheumatoid arthritis, according to a study published in <em>Journal of Autoimmunity</em>. Similarly, people with low vitamin D levels reported more symptoms of osteoarthritis, like knee pain and difficulty walking, according to research by the American College of Rheumatology.</p> <p><strong>Feet</strong></p> <p>Stress fractures – microfractures that often occur in small bones due to overuse – are fairly common injuries, particularly in people who participate in high impact activities, like running, or people who are significantly overweight. According to a study published in <em>The Journal of Foot and Ankle Surgery</em>, vitamin D may reduce stress fractures by helping improve bone density.</p> <p><em><span id="docs-internal-guid-41d08e27-7fff-fd5c-6a8f-fc6514936626">Written by Charlotte Hilton Andersen.

Three simple ways to cut cancer risk for over-70s

<p dir="ltr">Over-70s could cut their cancer risk by up to 61 percent through a combination of high-dose vitamin D, omega-3s, and a home strength exercise program, according to new research.</p> <p dir="ltr">The study, published in <em><a href="https://www.frontiersin.org/articles/10.3389/fragi.2022.852643/full" target="_blank" rel="noopener">Frontiers in Ageing</a></em>, tested the effect of high daily doses of vitamin D3 (a form of vitamin D used in supplements), daily omega-3 supplements, and at-home exercise when combined with each other and in isolation over three years.</p> <p dir="ltr">2,157 healthy participants over the age of 70 were given either a combination of the supplements and exercise, single supplements, or a placebo between December 2012 and 2017, with the researchers then assessing the impact of the supplements on the risk of invasive cancers.</p> <p dir="ltr">Though each supplement was found to have a slight benefit when taken alone, the team found the combination of exercise and supplements had a significant effect.</p> <p dir="ltr">“This is the first randomised controlled trial to show that the combination of daily vitamin D3, supplemental marine omega-3s, and a simple home exercise program may be effective in the prevention of invasive cancer among generally healthy and active adults aged 70 and older,” Dr Heike Bischoff-Ferrari of the University Hospital Zurich, and the study’s first author, <a href="https://www.scimex.org/newsfeed/over-70-vitamin-d,-omega-3s,-and-exercise-could-cut-your-cancer-risk-by-61" target="_blank" rel="noopener">said</a>.</p> <p dir="ltr">“Our results, although based on multiple comparisons and requiring replication, may prove to be beneficial for reducing the burden of cancer.”</p> <p dir="ltr">But Dr Bischoff-Ferrari and her team didn’t pick these supplements by chance.</p> <p dir="ltr">In fact, previous studies have shown that vitamin D stops cancer cells from growing, while omega-3 may prevent normal cells from becoming cancerous.</p> <p dir="ltr">Even exercise has been found to reduce inflammation and improve immune function, which could also help prevent cancer, according to <em><a href="https://www.eurekalert.org/news-releases/950364" target="_blank" rel="noopener">Eureka Alert!</a></em>.</p> <p dir="ltr">But, there have been few robust clinical studies proving that using these three treatments can prevent cancer - which is why Dr Bischoff-Ferrari and her team came in.</p> <p dir="ltr">With their findings, Dr Bischoff-Ferrari said future studies should try to replicate their findings and continue following up with patients for more than three years to determine how long-term these benefits are.</p> <p><span id="docs-internal-guid-95d28c12-7fff-b582-b589-32ae86914c18"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Are you getting enough Vitamin D?

<div class="postIntro"><strong>Many people are deficient in this essential vitamin – are you one of them?</strong></div> <p>When it comes to a vitamin that protects against a long list of ills, it’s hard to go past vitamin D. As well as being essential for supporting normal growth and maintenance of bones, vitamin D supports the normal function of the immune system, the nervous system and normal muscle function.</p> <p>There are many research-backed reasons why vitamin D is imperative to healthy living: It may help improve moods, reduce risk of cancer, facilitate weight loss, and even reduce asthma attacks. It seems like every day there’s fresh evidence that vitamin D protects against some disease.</p> <p>It’s rather unfortunate then, that many of us simply aren’t getting enough of this essential vitamin. You’re probably aware that vitamin D is the sunshine vitamin: you make it when sunlight hits your skin. Yet thanks to workaholic (or TV-aholic) habits, most people don’t make enough. Another culprit is sunscreen and other cosmetics with UV filters which, while protecting us from skin cancer and the ageing effects of the sun, reduce the skin’s ability to synthesise vitamin D.</p> <p>Symptoms of vitamin D deficiency aren’t always easy to spot. On the more obvious end of the spectrum, being deficient in vitamin D can cause rickets (soft, weak bones) in children and thinning bones in the elderly, but it can also have more subtle effects, such as fatigue, cognitive impairment, joint pain, low immunity, depression, weight gain, and low calcium in the blood (because we need vitamin D to help absorb calcium). There’s even evidence to suggest that vitamin D deficiency plays a role in heart disease, diabetes, multiple sclerosis and cancer.</p> <p>It’s no wonder that leading infectious-disease expert Dr Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases in the USA, shares that he takes both vitamin C and vitamin D supplements to reduce susceptibility to infection, and recommends others do the same.</p> <p><img style="width: 500px; height: 281.25px;" src="https://oversixtydev.blob.core.windows.net/media/7842083/vitamin-1.jpg" alt="" data-udi="umb://media/27f0b7481f5a433589476e5ab260cff8" /></p> <p><strong>Who should take Vitamin D?</strong></p> <p>Anyone looking to support their immune system should consider supplementing their diet with vitamin D, but those in the following categories will particularly benefit:</p> <p><strong>You slather on SPF every day, use cosmetics with UV filters, or otherwise shun the sun. </strong>Sun exposure is our main source of vitamin D, and we get drastically less of it in autumn and winter – and also in summer, when judicious applications of sunscreen keeps a majority of the sun’s rays from penetrating the skin. If you spend most of your day indoors, you’re probably not getting enough vitamin D.</p> <p><strong>You avoid dairy or follow a vegan diet. </strong>Few foods naturally contain vitamin D, and foods that are fortified with vitamin D – milk, yoghurts, cheeses, some juices, and some breads – are often inadequate to deliver our daily dose. The best natural sources of vitamin D in the diet are oily fish such as salmon, mackerel and herring and oils from fish, including cod liver oil, according to research from the Vitamin D, Skin, and Bone Research Laboratory at Boston University Medical Center.</p> <p><strong>You have an inflammatory bowel disease, such as Crohn’s or ulcerative colitis. </strong>In fact, scientists are exploring whether taking supplemental vitamin D can help treat these chronic diseases, mainly by reducing inflammation.</p> <p><strong>You’re a senior citizen.</strong> Ageing is associated with decreased concentrations of vitamin D precursors in the skin. According to a study in the <em>American Journal of Clinical Nutrition</em>, 70-year-olds have a 75 percent reduced capacity to manufacture vitamin D in their skin compared to people in their twenties. So as you get older, you actually need more vitamin D because your body isn’t as good at making it as it used to be.</p> <p><strong>You’re overweight or obese. </strong>Vitamin D is fat soluble, which means it’s readily taken up by fat cells – and the more fat cells you have, the more vitamin D gets snatched up, making it less available for use by the body. A study in the <em>American Journal of Clinical Nutrition</em> confirms that obesity is linked with vitamin D deficiency. It’s also been shown that bariatric surgery can lead to vitamin D and calcium deficiencies.<strong> </strong></p> <p><strong>You have a family history of osteoporosis</strong>. Osteoporosis is a condition where you lose too much bone or don’t make enough to replace the bone that you normally lose. Vitamin D and calcium work together to build and maintain healthy bones.<strong> </strong></p> <p><strong>You’re pregnant.</strong> Expecting mothers with low blood levels of vitamin D during pregnancy are at higher risk for potentially fatal high blood pressure (preeclampsia), early delivery and low birth weight babies. Mothers deficient in D are also more likely to require a C-section delivery and are at greater risk for infections, says Dr Michael Holick, professor and director of the Vitamin D, Skin and Bone Research Laboratory at Boston University Medical Center. Vitamin D receptors in the uterine muscle may strengthen contractions during labour, as well as boosting immunity for mother and baby, he says.</p> <p><strong>You have dark skin.</strong> Those with a darker complexion have high melanin in the skin – the pigment that acts as a natural sunscreen, therefore you will absorb less vitamin D naturally.</p> <p><a rel="noopener" href="https://johanw2.sg-host.com/our-products/lipo-sachets-vitamin-d/" target="_blank"><img style="width: 500px; height: 281.25px;" src="https://oversixtydev.blob.core.windows.net/media/7842084/vitamin-2.jpg" alt="" data-udi="umb://media/badd8e1953934bd1a3dc68b84a2534f6" /></a></p> <p><strong>Why take VITAMIN D LIPO-SACHETS?</strong></p> <p>Incorporating a daily vitamin D supplement into your diet will ensure you’re getting adequate levels of this wonder vitamin to achieve its amazing benefits. <a rel="noopener" href="https://johanw2.sg-host.com/our-products/lipo-sachets-vitamin-d/" target="_blank">Vitamin D Lipo-Sachets</a> are convenient, one-a-day sachets that come in a delicious melon flavour and pleasant gel-like consistency that you can consume as is or add to cold water or juice.</p> <p>This simple addition to your daily diet will promote calcium absorption, support healthy bone development, help support immune, nervous system and healthy muscle function, support healthy foetal development and enhance general health and wellbeing.

The truth about vitamin D

<p>It’s one of life’s little ironies that we live in a country with abundant sunshine yet every year the rates of vitamin D deficiency in the Australian population continue to soar.</p> <p>Health experts know the importance of maintaining adequate levels of vitamin D and there is increasing evidence that this is also a contributor to our overall health. While studies are still embryonic, there are signs that low levels of vitamin D is linked to serious illnesses such as heart disease, diabetes and some cancers.</p> <p>Vitamin D helps our body absorb calcium, and that’s a major factor for maintaining our bone health and muscle mass.</p> <p>As we get older, being vitamin D deficient is known to be a mitigating factor in increased falls and bone fractures, says <a href="https://www.osteoporosis.org.au/">Osteoporosis Australia</a>, with more than six million Australians known to have low bone density. Osteoporosis Australia is currently inviting people to visit their website to try the <a href="http://osteoporosisdtc.azurewebsites.net/home">'Know Your Bones' bone health assessment tool</a>.</p> <p>Experts say the best way to “top up” on vitamin D is to spend some time outdoors in the sunshine; especially recommended in winter.</p> <p>Australian Bureau of Statistics figures in 2011 found that by the end of winter, nearly 50 per cent of all Australians in Victoria, Tasmania and the ACT had a vitamin D deficiency, with NSW not far behind with around 40 per cent.</p> <p>It was only the sunnier states of Queensland, Western Australia and the Northern Territory that had far lower percentages – generally less than 20 per cent.</p> <p>While those percentages may fluctuate from year to year, experts agree that many of us need to rethink our relationship with the sun in the colder months. </p> <p>Professor Rebecca Mason, the head of physiology and deputy director of the Bosch Institute at Sydney Medical School at the University of Sydney, who has studied vitamin D for decades, says that exposing parts of our body – arms and legs, for example – to sunlight is by far the preferred way to get vitamin D.</p> <p>“Energy absorption from sunlight is absolutely critical to make vitamin D in skin and the high energy is only available from the UVB part of sunlight,” says Professor Mason. This means we need to try to get in the sun between 11am and 1pm on a daily basis in winter, she adds.</p> <p>However, there is a resistance to getting out there among many Australians, who are often worried about sun exposure and skin cancer as well as preferring to stay indoors.</p> <p>“One of the biggest problems with some older Australians is that they just don’t get outside enough,” says Professor Mason. “Mobility can be an issue, not being well enough and generally not wanting to go out.”</p> <p>There is a lot of confusing information on the internet about how much sun on your skin you need to maintain healthy vitamin D levels. It depends, in fact, on where you live. In Cairns, for example, you will probably only need about 10 minutes per day, whereas in Melbourne or Hobart, you will need at least 40 minutes. Unless you’re playing sport or doing something physical to keep you warm, this can be extremely difficult when it’s freezing cold outside.</p> <p>So are there any worthwhile alternatives? Not really, says Professor Mason, though some, like vitamin D supplements, may be “perfectly reasonable” if you have concerns about skin cancer or other medical, practical or cultural reasons why going out in the sunshine is not an option.</p> <p>“The main problem with supplements,” says Professor Mason, “is that we are becoming increasingly aware that being out in the sun has health benefits that are not necessarily just due to vitamin D.”</p> <p>While there are some foods that do contain vitamin D – such as fish with the skin left on, eggs, meat, some cereals, and margarine – these will only provide about 10 per cent of your daily requirement at best.</p> <p>The only way to find out if you are vitamin D deficient is to have a blood test. The best time to go is at the end of winter or early spring.</p> <p>There are no major physical symptoms if your vitamin D levels have dropped - unless you have very low levels. Then, you may notice general aches and pains, bone tenderness, and a much higher risk of bone fractures if you have a fall.</p> <p><em>Republished with permission of <a href="https://www.wyza.com.au/articles/health/the-truth-about-vitamin-d.aspx">Wyza.com.au.</a></em></p>

This vitamin could be the secret to stopping cold and flu

<p>Vitamin D isn’t just good for promoting good bone health. According to a new study published in the <a href="http://www.bmj.com/cgi/doi/10.1136/bmj.i6583" target="_blank"><strong><em><span style="text-decoration: underline;">British Medical Journal</span></em></strong></a>, taking a vitamin D supplement daily or weekly is as effective as the flu vaccine, cutting users’ chances of respiratory infection by 12 per cent.</p> <p>And, with the effectiveness of sun-safe messages like “slip, slop, slap, and wrap” some experts worry that many of us are covering up to the point where we don’t get any sunshine on our skin.</p> <p>The findings of the study support the observation that we’re most at risk of cold and flu during winter and spring, when our levels of vitamin D are running low.</p> <p>“The bottom line is that the protective effects of vitamin D supplementation are strongest in those who have the lowest vitamin D levels and when supplementation is given daily or weekly rather than in more widely spaced doses,” lead researcher Professor Adrian Martineau of the Queen Mary University of London said.</p> <p>Do you take a vitamin D supplement?

Veterans slam Prince Harry for untidy appearance

<p>It’s not every day that a member of the public gets to take the mickey out of the fifth-in-line for the British throne! During a recent visit to Southwick House in anticipation of the anniversary of D-Day, Prince Harry was jokingly berated by a 91-year-old WWII veteran for his casual appearance.</p> <p>“Where’s your bloody tie?” Ivor Anderson boldly asked the young royal, who replied “I was told not to wear a tie and then you all turn up wearing ties! I feel under-dressed.”</p> <p><img width="500" height="250" src="https://oversixtydev.blob.core.windows.net/media/21505/prince-harry-group_500x250.jpg" alt="Prince Harry Group"/></p> <p>Prince Harry was reportedly worried about his outfit before he even entered the room, asking “Are they all wearing ties in there? I should have worn a tie! Oh well, it’s too late now.”</p> <p>Anderson later said he had a spare one, but couldn’t lend it to the Prince as he didn’t have his “wings”, a term used to describe the badge worn on a tie by members of the air force.</p> <p><strong>Related links:</strong></p> <p><a href="/news/news/2016/05/prince-harry-closes-the-invictus-games-with-a-kiss/"><span style="text-decoration: underline;"><em><strong>Prince Harry closes the Invictus Games with a kiss</strong></em></span></a></p> <p><a href="/news/news/2016/05/piers-morgan-says-harry-would-make-a-better-king-than-william/"><span style="text-decoration: underline;"><em><strong>Piers Morgan says Harry would make a better king than William</strong></em></span></a></p> <p><a href="/news/news/2016/05/prince-harry-meets-australian-invictus-competitors/"><span style="text-decoration: underline;"><em><strong>Star-struck Aussie Invictus competitors meet Prince Harry</strong></em></span></a></p>
