What’s the difference between MSG and table salt? A chemist explains

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p>It’s dinner time. You’ve worked hard to prepare a nutritious and tasty meal. But after taking your first bite you feel something is missing. Perhaps you should have added more salt? Pepper? Or maybe even something more exotic like monosodium glutamate, better known as MSG?</p> <p>There are many <a href="https://theconversation.com/explainer-what-are-e-numbers-and-should-you-avoid-them-in-your-diet-43908">food additives</a> used in both home cooking and commercial products. These ingredients improve the flavour, smell, texture, appearance and longevity of foods.</p> <p>Salt and MSG are two well-known food additives. Both contain sodium, but there are plenty of differences which you can use to your benefit.</p> <h2>What is a salt?</h2> <p>Salts are made of positively and negatively charged components called ions. Salts generally dissolve in water, and are brittle. The names of salts often feature a metal (positively charged) followed by a non-metal (negatively charged).</p> <p>The common kitchen ingredient we call “salt” is just one type of salt. To distinguish it from all other salts, we should more specifically refer to it as “table salt”. Chemically, it’s sodium chloride.</p> <h2>Sodium chloride</h2> <p>After the quick chemistry lesson above, we can see that table salt, sodium chloride, contains a positively charged sodium and a negatively charged chlorine.</p> <p>These charged components are arranged in crystals of salt in a regular repeating pattern. Each sodium ion is surrounded by six chloride ions and each chloride ion is surrounded by six sodium ions. This arrangement gives the crystal a “cubic” form. If you look closely at salt, you may see cube-shaped crystals.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&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/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">The chemical structure of table salt forms a cube of sodium and chloride ions.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/sodium-chloride-nacl-structure-ionic-crystal-2417242373">Sandip Neogi/Shutterstock</a></span></figcaption></figure> <p>Sodium chloride is very abundant. It is found <a href="https://theconversation.com/i-have-always-wondered-why-is-the-sea-salty-83489">dissolved in Earth’s oceans</a>. Mineral deposits of salt, known as halite or rock salt, formed from the evaporation and crystallisation of ancient seas.</p> <p>Depending on the source, the salt may contain many other trace minerals that can even add colour to it, such as the pink-coloured Himalayan salt from Pakistan. Salt can also be fortified with <a href="https://www.who.int/publications/i/item/9789240053717">sodium iodide</a> as a public health measure.</p> <p>Describing the taste of salt is quite difficult without using the word “salty”. It’s a very common food additive, as it is so abundant and versatile. It is an essential ingredient for many traditional food preservation techniques for meats (pork and fish), vegetables (kimchi, sauerkraut and pickles), and dairy (cheese and butter).</p> <p>Salt is considered a universal flavouring agent. It can mask bitter flavours and bring out sweet, sour and <a href="https://theconversation.com/the-asian-roots-of-umami-the-fifth-taste-central-to-thanksgiving-fare-50699">umami</a> (savoury) ones.</p> <p>Despite popular depictions of <a href="https://theconversation.com/that-neat-and-tidy-map-of-tastes-on-the-tongue-you-learned-in-school-is-all-wrong-44217">taste maps</a>, there is no one place on the tongue where we taste salt. Other sodium salts can also give a “salty” taste, but the effect declines (and can even turn to bitter) with negatively charged components other than chloride.</p> <h2>MSG or monosodium glutamate</h2> <p>Monosodium glutamate is also a salt. The glutamate is the negatively charged form of glutamic acid, an amino acid that is found in nature as a building block of proteins.</p> <p>MSG, and more generally glutamates, are found in a wide range of foods including tomatoes, Parmesan cheese, soy sauce, dried seaweeds, Worcestershire sauce and protein-rich foods. All of these foods impart umami flavours, which are described as savoury or meaty.</p> <p>Commercial MSG is not extracted from the environment but produced by bacterial fermentation. Glucose is converted to glutamic acid, which is further processed by adding sodium hydroxide to form MSG (and water).</p> <p>MSG is sold as crystals, but they have a long, prismatic shape rather than the cubic form of sodium chloride. It’s worth tasting a few crystals of MSG directly to experience the native taste of umami.</p> <p>Despite decades of bad press and concern, <a href="https://theconversation.com/msg-is-back-is-the-idea-its-bad-for-us-just-a-myth-or-food-science-237871">MSG is considered safe</a> to consume in the concentrations typically found in or added to foods.</p> <p>Table salt and MSG both contain sodium, but at different percentages of the total weight: table salt has around 40% sodium, versus just 14% in MSG. You are also more likely to be routinely adding table salt to your food rather than MSG.</p> <p>Eating too much sodium is well known to be unhealthy. <a href="https://theconversation.com/this-salt-alternative-could-help-reduce-blood-pressure-so-why-are-so-few-people-using-it-221409">Potassium-enriched substitutes</a> have been suggested for a range of health benefits.</p> <h2>A flavour enhancer</h2> <p>The flavour of MSG can be elevated further by combining it with other food additives, known as sodium ribonucleotides.</p> <p>Japanese and Korean cooks figured this secret out long before chemists, as boiling dried fish and seaweed produces foundation stocks (dashi) containing a mix of naturally sourced glutamates and ribonucleotides.</p> <p>Ribonucleotides are classified as “generally considered as safe” by <a href="https://www.cfsanappsexternal.fda.gov/scripts/fdcc/index.cfm?set=FoodSubstances&amp;id=DISODIUMINOSINATE&amp;sort=Sortterm_ID&amp;order=ASC&amp;startrow=1&amp;type=basic&amp;search=disodium">food standards authorities</a>. Humans consume many grams of the natural equivalent in their diets.</p> <p>What can be more problematic are the carbohydrates- and fat-rich foods that have their flavours enhanced, which can potentially lead us to eat excessive calories.</p> <p>The combination of MSG and ribonucleotides produces a more-ish sensation. Next time you see a bag of potato chips or instant noodles, have a quick look to see if it contains both MSG (E621) and a ribonucleotide source (E627–E635).</p> <p>I personally keep a jar of MSG in my kitchen. A little goes a long way to elevate a soup, stew or sauce that isn’t quite tasting the way you want it to, but without adding too much extra sodium.<!-- Below is The Conversation's page counter tag.

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

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/emma-beckett-22673">Emma Beckett</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Rice is a <a href="http://www.ipni.net/publication/bci.nsf/0/42A2EA40E95CBD1385257BBA006531E9/$FILE/Better%20Crops%20International%202002-3%20p03.pdf">culinary staple</a> in Australia and around the world.</p> <p>It might seem like a given that brown rice is healthier than white and official <a href="https://www.eatforhealth.gov.au/eating-well/healthy-recipes/recipe-modification-tips">public health resources</a> often recommend brown rice instead of white as a “healthy swap”.</p> <p>But <a href="https://pubmed.ncbi.nlm.nih.gov/34441728/">Australians definitely prefer white rice</a> over brown. So, what’s the difference, and what do we need to know when choosing rice?</p> <h2>What makes rice white or brown?</h2> <p>Rice “grains” are technically seeds. A complete, whole rice seed is called a “paddy”, which has <a href="https://www.fao.org/4/t0567e/t0567e07.htm">multiple parts</a>:</p> <ol> <li>the “hull” is the hard outer layer which protects the seed</li> <li>the “bran”, which is a softer protective layer containing the seed coat</li> <li>the “germ” or the embryo, which is the part of the seed that would develop into a new plant if was germinated</li> <li>the “endosperm”, which makes up most of the seed and is essentially the store of nutrients that feeds the developing plant as a seed grows into a plant.</li> </ol> <p>Rice needs to be <a href="https://www.tandfonline.com/doi/pdf/10.1080/87559128509540778">processed</a> for humans to eat it.</p> <p>Along with cleaning and drying, the hard hulls are removed since we can’t digest them. This is how <a href="https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1541-4337.12449">brown rice is made</a>, with the other three parts of the rice remaining intact. This means brown rice is regarded as a “wholegrain”.</p> <p>White rice, however, is a “refined” grain, as it is <a href="https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1541-4337.12449">further polished</a> to remove the bran and germ, leaving just the endosperm. This is a mechanical and not a chemical process.</p> <h2>What’s the difference, nutritionally?</h2> <p>Keeping the bran and the germ means <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/cche.10322">brown rice has more</a> magnesium, phosphorus, potassium B vitamins (niacin, folate, riboflavin and pyridoxine), iron, zinc and fibre.</p> <p>The germ and the bran also contain more bioactives (compounds in foods that aren’t essential nutrients but have health benefits), like <a href="https://www.mdpi.com/1420-3049/28/2/532#:%7E:text=Brown%20rice%20(BR)%20is%20obtained,and%20phenolic%20compounds%20%5B3%5D.">oryzanols and phenolic compounds</a> which have antioxidant effects.</p> <p>But that doesn’t mean white rice is just empty calories. It <a href="https://www.glnc.org.au/wp-content/uploads/2011/04/GLNC_Rice-factsheet_WEB.pdf">still contains</a> vitamins, minerals and some fibre, and is low in fat and salt, and is naturally gluten-free.</p> <p>White and brown rice actually have <a href="https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1541-4337.12449">similar</a> amounts of calories (or kilojoules) and total carbohydrates.</p> <p>There are studies that show eating more white rice is linked to <a href="https://diabetesjournals.org/care/article/43/11/2625/35820/A-Global-Perspective-on-White-Rice-Consumption-and">a higher risk</a> of type 2 diabetes. But it is difficult to know if this is down to the rice itself, or other related factors such as socioeconomic variables or other dietary patterns.</p> <h2>What about the glycaemic index?</h2> <p>The higher fibre means brown rice has a <a href="https://www.sciencedirect.com/science/article/pii/S0002916523314862">lower glycaemic index</a> (GI), meaning it raises blood sugar levels more slowly. But this is highly variable between different rices within the white and brown categories.</p> <p>The <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/carbohydrates-and-the-glycaemic-index#:%7E:text=The%20glycaemic%20index%20(GI)%20is,simple'%20or%20'complex'.">GI system</a> uses low (less than 55), medium (55–70) and high (above 70) categories. <a href="https://glycemicindex.com/gi-search/?food_name=rice&amp;product_category=&amp;country=&amp;gi=&amp;gi_filter=&amp;serving_size_(g)=&amp;serving_size_(g)_filter=&amp;carbs_per_serve_(g)=&amp;carbs_per_serve_(g)_filter=&amp;gl=&amp;gl_filter=">Brown rices</a> fall into the low and medium categories. <a href="https://glycemicindex.com/gi-search/?food_name=rice&amp;product_category=&amp;country=&amp;gi=&amp;gi_filter=&amp;serving_size_(g)=&amp;serving_size_(g)_filter=&amp;carbs_per_serve_(g)=&amp;carbs_per_serve_(g)_filter=&amp;gl=&amp;gl_filter=">White rices</a> fall in the medium and high.</p> <p>There are specific <a href="https://www.gisymbol.com/low-gi-products/sunrice-doongara-low-gi-white-clever-rice-1kg/">low-GI types available</a> for both white and brown types. You can also lower the GI of rice by <a href="https://pubs.acs.org/doi/abs/10.1021/jf503203r">heating and then cooling it</a>. This process converts some of the “available carbohydrates” into “resistant starch”, which then functions like dietary fibre.</p> <h2>Are there any benefits to white rice?</h2> <p>The <a href="https://www.realsimple.com/brown-rice-vs-white-rice-8417468#:%7E:text=The%20eating%20experience%20between%20these,chewier%20texture%20and%20nuttier%20flavor.">taste and textural qualities</a> of white and brown rices differ. White rice tends to have a softer texture and more mild or neutral flavour. Brown rice has a chewier texture and nuttier flavour.</p> <p>So, while you can technically substitute brown rice into most recipes, the experience will be different. Or other ingredients may need to be added or changed to create the desired texture.</p> <p>Removing more of the outer layers may also reduce the levels of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10375490/">contaminants</a> such as pesticides.</p> <h2>We don’t just eat rice</h2> <p>Comparing white and brown rice seems like an easy way to boost nutritional value. But just because one food (brown rice) is more nutrient-dense doesn’t make the other food (white rice) “bad”.</p> <p>Ultimately, it’s not often that we eat just rice, so we don’t need the rice we choose to be the perfect one. Rice is typically the staple base of a more complex dish. So, it’s probably more important to think about what we eat with rice.</p> <p>Adding vegetables and lean proteins to rice-based dishes can easily add the micronutrients, bioactives and fibre that white rice is comparatively lacking, and this can likely do more to contribute to diet quality than eating brown rice instead.<!-- Below is The Conversation's page counter tag.

Could the shingles vaccine lower your risk of dementia?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/ibrahim-javed-1552271">Ibrahim Javed</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>A <a href="https://www.nature.com/articles/s41591-024-03201-5">recent study</a> has suggested Shingrix, a relatively new vaccine given to protect older adults against shingles, may delay the onset of dementia.</p> <p>This might seem like a bizarre link, but actually, <a href="https://pubmed.ncbi.nlm.nih.gov/34697158/">research</a> has previously shown an older version of the shingles vaccine, Zostavax, reduced the risk of dementia.</p> <p>In this new study, published last week in the journal Nature Medicine, researchers from the United Kingdom found Shingrix delayed dementia onset by 17% compared with Zostavax.</p> <p>So how did the researchers work this out, and how could a shingles vaccine affect dementia risk?</p> <h2>From Zostavax to Shingrix</h2> <p>Shingles is a viral infection caused by the varicella-zoster virus. It causes <a href="https://www.healthdirect.gov.au/shingles">painful rashes</a>, and affects older people in particular.</p> <p>Previously, Zostavax was used to vaccinate against shingles. It was administered as a single shot and provided good protection for about <a href="https://immunisationhandbook.health.gov.au/contents/vaccine-preventable-diseases/zoster-herpes-zoster">five years</a>.</p> <p>Shingrix has been developed based on a newer vaccine technology, and is thought to offer stronger and longer-lasting protection. Given in two doses, it’s now the preferred option for shingles vaccination in Australia and elsewhere.</p> <p>In November 2023, Shingrix replaced Zostavax on the <a href="https://www.health.gov.au/news/national-immunisation-program-changes-to-shingles-vaccination-from-1-november-2023">National Immunisation Program</a>, making it available for free to those at highest risk of complications from shingles. This includes all adults aged 65 and over, First Nations people aged 50 and older, and younger adults with certain medical conditions that affect their immune systems.</p> <h2>What the study found</h2> <p>Shingrix was approved by the US Food and Drugs Administration in <a href="https://www.drugs.com/history/shingrix.html">October 2017</a>. The researchers in the new study used the transition from Zostavax to Shingrix in the United States as an opportunity for research.</p> <p>They selected 103,837 people who received Zostavax (between October 2014 and September 2017) and compared them with 103,837 people who received Shingrix (between November 2017 and October 2020).</p> <p>By analysing data from electronic health records, they found people who received Shingrix had a 17% increase in “diagnosis-free time” during the follow-up period (up to six years after vaccination) compared with those who received Zostavax. This was equivalent to an average of 164 extra days without a dementia diagnosis.</p> <p>The researchers also compared the shingles vaccines to other vaccines: influenza, and a combined vaccine for tetanus, diphtheria and pertussis. Shingrix and Zostavax performed around 14–27% better in lowering the risk of a dementia diagnosis, with Shingrix associated with a greater improvement.</p> <p>The benefits of Shingrix in terms of dementia risk were significant for both sexes, but more pronounced for women. This is not entirely surprising, because we know women have <a href="https://www.alzheimers.org.uk/blog/why-dementia-different-women">a higher risk</a> of developing dementia due to interplay of biological factors. These include being more sensitive to certain genetic mutations associated with dementia and hormonal differences.</p> <h2>Why the link?</h2> <p>The idea that vaccination against viral infection can lower the risk of dementia has been around for more than two decades. Associations have been <a href="https://pubmed.ncbi.nlm.nih.gov/11762573/">observed</a> between vaccines, such as those for diphtheria, tetanus, polio and influenza, and subsequent dementia risk.</p> <p>Research has shown Zostavax vaccination can <a href="https://bmjopen.bmj.com/content/11/10/e045871">reduce the risk</a> of developing dementia by 20% compared with people who are unvaccinated.</p> <p>But it may not be that the vaccines themselves protect against dementia. Rather, it may be the resulting lack of viral infection creating this effect. Research indicates bacterial infections in the gut, as well as viral infections, are associated with a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10169152/">higher risk of dementia</a>.</p> <p>Notably, untreated infections with herpes simplex (herpes) virus – closely related to the varicella-zoster virus that causes shingles – can <a href="https://alz-journals.onlinelibrary.wiley.com/doi/10.1002/trc2.12119">significantly increase</a> the risk of developing dementia. Research has also shown shingles increases the risk of a later dementia diagnosis.</p> <p>The mechanism is not entirely clear. But there are two potential pathways which may help us understand why infections could increase the risk of dementia.</p> <p>First, certain molecules are produced when a baby is developing in the womb to help with the body’s development. These molecules have the potential to cause inflammation and accelerate ageing, so the production of these molecules is silenced around birth. However, viral infections such as shingles can <a href="https://doi.org/10.1016/j.virol.2018.07.011">reactivate</a> the production of these molecules in adult life which could <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8717685/#:%7E:text=The%20disease%20mechanisms%20of%20AD,may%20lead%20to%20new%20therapies.">hypothetically lead to dementia</a>.</p> <p>Second, in Alzheimer’s disease, a specific protein called Amyloid-β go rogue and kill brain cells. Certain proteins produced by viruses <a href="https://www.biorxiv.org/content/10.1101/2024.05.16.594465v1">such as COVID</a> and <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.202001299">bad gut bacteria</a> have the potential to support Amyloid-β in its toxic form. In laboratory conditions, these proteins have been shown to <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1003537">accelerate the onset</a> of dementia.</p> <h2>What does this all mean?</h2> <p>With an ageing population, the burden of dementia is only likely to become greater in the years to come. There’s a lot more we have to learn about the causes of the disease and what we can potentially do to prevent and treat it.</p> <p>This new study has some limitations. For example, time without a diagnosis doesn’t necessarily mean time without disease. Some people may have underlying disease with delayed diagnosis.</p> <p>This research indicates Shingrix could have a silent benefit, but it’s too early to suggest we can use antiviral vaccines to prevent dementia.</p> <p>Overall, we need more research exploring in greater detail how infections are linked with dementia. This will help us understand the root causes of dementia and design potential therapies.<!-- Below is The Conversation's page counter tag.

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a></em></p> <p>Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can <a href="https://theconversation.com/is-winter-miserable-for-wildlife-108734">quickly turn chilly and dangerous</a> for people and pups alike.</p> <p>Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs <a href="https://doi.org/10.3390/ani11113302">when the weather gets cold</a>. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog.</p> <p>I am an <a href="https://www.vetmed.ucdavis.edu/faculty/erik-olstad">assistant professor</a> at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets.</p> <h2>Breed and age differences</h2> <p>Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia.</p> <p>Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat.</p> <p>Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather.</p> <h2>When is my dog too cold?</h2> <p>Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable.</p> <p>Just like people, <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">dogs can get frostbite</a>. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; <a href="https://www.britannica.com/science/ulcer">or ulceration</a>.</p> <p>Other <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">serious signs of hypothermia</a> include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog.</p> <p>Getting your dog a <a href="https://www.cnn.com/cnn-underscored/pets/best-winter-dog-coats-jackets">sweater or jacket</a> and <a href="https://www.akc.org/expert-advice/vets-corner/protect-dogs-paws-snow-ice-salt/">paw covers</a> can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it.</p> <h2>Road salt dangers</h2> <p>Road salt that treats ice on streets and sidewalks <a href="https://www.cbc.ca/news/canada/kitchener-waterloo/ice-salt-toxic-for-pets-1.5020088">can also harm dogs</a>. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws.</p> <p>Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can <a href="https://www.petpoisonhelpline.com/pet-tips/my-dog-ate-road-salt-will-they-be-okay/">disrupt critical body functions</a> in dogs.</p> <p>Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or <a href="https://www.akc.org/expert-advice/lifestyle/how-to-make-your-own-paw-balm-for-winter/">paw pad balm</a> to the skin of the paw pads can also help protect your pet’s paws from irritation.</p> <h2>Antifreeze risks</h2> <p><a href="https://www.britannica.com/science/antifreeze-chemical-substance">Antifreeze, or ethylene glycol</a>, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing.</p> <p>Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have <a href="https://www.petpoisonhelpline.com/pet-owner-blog/antifreeze-poisoning/">permanent kidney damage or die</a>.</p> <p>There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment.</p> <p>When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible. Try some <a href="https://www.akc.org/expert-advice/lifestyle/great-indoor-games-to-play-with-your-dog/">indoor activities</a>, like hide-and-seek with low-calorie treats, fetch or even an interactive obstacle course. Food puzzles can also keep your dog mentally engaged during indoor time.</p> <p>Although winter presents some unique challenges, it can still be an enjoyable and healthy time for you and your canine companion.<!-- Below is The Conversation's page counter tag.

I want to eat healthily. So why do I crave sugar, salt and carbs?

<p><em><a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>We all want to eat healthily, especially as we reset our health goals at the start of a new year. But sometimes these plans are sabotaged by powerful cravings for sweet, salty or carb-heavy foods.</p> <p>So why do you crave these foods when you’re trying to improve your diet or lose weight? And what can you do about it?</p> <p>There are many reasons for craving specific foods, but let’s focus on four common ones:</p> <h2>1. Blood sugar crashes</h2> <p>Sugar is a key energy source for all animals, and its taste is one of the most basic sensory experiences. Even without specific sweet taste receptors on the tongue, a strong preference for sugar can develop, indicating a mechanism beyond taste alone.</p> <p>Neurons <a href="https://www.nature.com/articles/s41593-021-00982-7">responding to sugar</a> are activated when sugar is delivered to the gut. This can increase appetite and make you want to consume more. Giving into cravings also drives an appetite for more sugar.</p> <p>In the long term, research suggests a high-sugar diet can affect <a href="https://www.bmj.com/content/369/bmj.m2382">mood</a>, digestion and <a href="https://pubmed.ncbi.nlm.nih.gov/33339337/">inflammation</a> in the <a href="https://www.science.org/doi/10.1126/scitranslmed.aay6218?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">gut</a>.</p> <p>While there’s a lot of <a href="https://www.sciencedirect.com/science/article/pii/S0149763402000040?via%3Dihub#aep-section-id23">variation between individuals</a>, regularly eating sugary and high-carb foods can lead to <a href="https://pubmed.ncbi.nlm.nih.gov/30951762/">rapid spikes and crashes</a> in blood sugar levels. When your blood sugar drops, your body can respond by craving quick sources of energy, often in the form of sugar and carbs because these deliver the fastest, most easily accessible form of energy.</p> <h2>2. Drops in dopamine and serotonin</h2> <p>Certain neurotransmitters, such as <a href="https://pubmed.ncbi.nlm.nih.gov/30595479/">dopamine</a>, are involved in the reward and pleasure centres of the brain. Eating sugary and carb-rich foods can trigger the release of dopamine, creating a pleasurable experience and reinforcing the craving.</p> <p>Serotonin, the feel-good hormone, suppresses <a href="https://www.sciencedirect.com/science/article/pii/S1569733910700886">appetite</a>. Natural changes in serotonin can influence daily fluctuations in mood, energy levels and attention. It’s also associated with eating more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5829131/">carb-rich snacks in the afternoon</a>.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/21985780/">Low carb diets</a> may reduce serotonin and lower mood. However, a recent systematic review suggests little association between these diets and risk for <a href="https://www.sciencedirect.com/science/article/pii/S0165032722013933?via%3Dihub">anxiety and depression</a>.</p> <p>Compared to men, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4189179/">women tend to crave more carb rich foods</a>. Feeling irritable, tired, depressed or experiencing carb cravings are part of premenstrual <a href="https://pubmed.ncbi.nlm.nih.gov/29218451/">symptoms</a> and could be <a href="https://www.ncbi.nlm.nih.gov/books/NBK560698/">linked to</a> reduced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9928757/">serotonin levels</a>.</p> <h2>3. Loss of fluids and drops in blood sugar and salt</h2> <p>Sometimes our bodies crave the things they’re missing, such as hydration or even salt. A low-carb diet, for example, <a href="https://www.ncbi.nlm.nih.gov/books/NBK537084/">depletes</a> insulin levels, decreasing sodium and water retention.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S1933287419302673">Very low-carb diets</a>, like ketogenic diets, induce “ketosis”, a metabolic state where the body switches to using fat as its primary energy source, moving away from the usual dependence on carbohydrates.</p> <p>Ketosis is often associated with increased urine production, further contributing to potential fluid loss, electrolyte imbalances and salt cravings.</p> <h2>4. High levels of stress or emotional turmoil</h2> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214609/">Stress</a>, boredom and emotional turmoil can lead to cravings for comfort foods. This is because stress-related hormones can impact our appetite, satiety (feeling full) and food preferences.</p> <p>The stress hormone <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425607/">cortisol</a>, in particular, can drive cravings for <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">sweet comfort foods</a>.</p> <p>A <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">2001 study</a> of 59 premenopausal women subjected to stress revealed that the stress led to higher calorie consumption.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/37295418/">A more recent study</a> found chronic stress, when paired with high-calorie diet, increases food intake and a preference for sweet foods. This shows the importance of a healthy diet during stress to prevent weight gain.</p> <h2>What can you do about cravings?</h2> <p>Here are four tips to curb cravings:</p> <p><strong>1) don’t cut out whole food groups.</strong> Aim for a well-balanced diet and make sure you include:</p> <ul> <li> <p><em>sufficient protein</em> in your meals to help you feel full and reduce the urge to snack on sugary and carb-rich foods. Older adults should aim for 20–40g protein per meal with a particular focus on <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/jhn.12838">breakfast and lunch</a> and an overall daily protein intake of at least <a href="https://apps.who.int/iris/handle/10665/43411">0.8g</a> per kg of body weight for <a href="https://pubmed.ncbi.nlm.nih.gov/35187864/">muscle health</a></p> </li> <li> <p><em>fibre-rich foods</em>, such as vegetables and whole grains. These make you feel full and <a href="https://pubmed.ncbi.nlm.nih.gov/32142510/">stabilise your blood sugar</a> levels. Examples include broccoli, quinoa, brown rice, oats, beans, lentils and bran cereals. Substitute refined carbs high in sugar like processed snack bars, soft drink or baked goods for more complex ones like whole grain bread or wholewheat muffins, or nut and seed bars or energy bites made with chia seeds and oats</p> </li> </ul> <p><strong>2) manage your stress levels.</strong> Practise stress-reduction techniques like meditation, deep breathing, or yoga to manage emotional triggers for cravings. Practising <a href="https://pubmed.ncbi.nlm.nih.gov/30570305/">mindful eating</a>, by eating slowly and tuning into bodily sensations, can also reduce daily calorie intake and curb cravings and stress-driven eating</p> <p><strong>3) get enough sleep.</strong> Aim for <a href="https://pubmed.ncbi.nlm.nih.gov/33054337/">seven to eight</a> hours of quality sleep per night, with a minimum of seven hours. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9031614/">Lack of sleep</a> can disrupt hormones that regulate hunger and cravings</p> <p><strong>4) control your portions.</strong> If you decide to indulge in a treat, control your portion size to avoid overindulging.</p> <p>Overcoming cravings for sugar, salt and carbs when trying to eat healthily or lose weight is undoubtedly a formidable challenge. Remember, it’s a journey, and setbacks may occur. Be patient with yourself – your success is not defined by occasional cravings but by your ability to manage and overcome them.<!-- Below is The Conversation's page counter tag.

Influencer announces tragic death of six-week-old son

<p>TikTok influencer Veruca Salt, real name Kimberley Summer Hartley, took to Instagram to announce the tragic death of her six-week-old son, Cash. </p> <p>The Gold Coast - based influencer, 25, shared the tragic news just one day after she posted a TikTok of her taking her newborn bub out for his first hospital visit, as he hadn't pooped in seven days. </p> <p>On Monday morning she revealed that her son “died in his sleep”. </p> <p>“It is with a heavy heart that I’m writing this,” she wrote.</p> <p>“My baby died in his sleep on Monday morning. I don’t know what happened, he is having an autopsy this week but it is unlikely that I’ll ever have an answer.</p> <p>“I’m just saying this because people are still commenting on my TikToks saying how happy I look with him and ‘just wait for the toddler stage’ and stuff and I (really) can’t take it anymore. I’m really sorry.”</p> <p>In her most recent <a href="https://www.tiktok.com/@verucasalt444/video/7332609198599032065?is_from_webapp=1&sender_device=pc&web_id=7142332295764346370" target="_blank" rel="noopener">TikTok</a>, she shared a clip of her grieving her son's death with the caption: "I knew he was dead but there was a part of me that really thought they were gonna wake him up." </p> <p>Fans have shared their condolences. </p> <p>"We are all standing by you Veruca.

Slashing salt can save lives – and it won’t hurt your hip pocket or tastebuds

It <a href="https://www.nature.com/articles/s41569-018-0004-1">raises blood pressure</a>, which increases the risk of <a href="https://www.ahajournals.org/doi/full/10.1161/HYPERTENSIONAHA.119.14240">heart disease and stroke</a>.</p> <p>About <a href="https://www.aihw.gov.au/reports/risk-factors/high-blood-pressure/contents/summary">one in three</a> Australians has high blood pressure, and eating too much salt is the biggest individual contributor.</p> <p>Unfortunately, the average Australian eats far too much salt – <a href="https://onlinelibrary.wiley.com/doi/abs/10.5694/mja17.00394">almost double</a> the recommended daily maximum of 5 grams, equivalent to <a href="https://www.heartfoundation.org.au/sodium-and-salt-converter#:%7E:text=We%20recommend%20adults%20eat%20less,about%201%20teaspoon%20a%20day">a teaspoon</a>.</p> <p>Australian governments know excessive salt intake is a big problem. That’s why in <a href="https://www.health.gov.au/resources/publications/national-preventive-health-strategy-2021-2030?language=en">2021 they set a target</a> to reduce salt intake by at least 30% by 2030.</p> <p>It’s an ambitious and worthy goal. But we’re still eating too much salt and we don’t have the policies to change that.</p> <h2>Most of the salt we eat is added to food during manufacturing</h2> <p>Most of the salt Australians eat doesn’t come from the shaker on the table. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7231587/">About three-quarters</a> of it is added to food during manufacturing.</p> <p>This salt is hidden in everyday staples such as bread, cheese and processed meats. Common foods such as ready-to-eat pasta meals or a ham sandwich can have up to half our total recommended salt intake.</p> <h2>Salt limits are the best way to cut salt intake</h2> <p>Reducing the amount of salt added to food during manufacturing is the most effective way to reduce intake.</p> <p>Salt limits can help us do that. They work by setting limits on how much salt can be added to different kinds of food, such as bread or biscuits. To meet these limits, companies need to change the recipes of their products, reducing the amount of salt.</p> <p>Under salt limits, the United Kingdom reduced salt intake <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.120.16649">by 20% in about a decade</a>. <a href="https://www.nature.com/articles/s41371-021-00653-x">South Africa</a> is making even faster gains. Salt limits are cheap and easy to implement, and can get results quickly.</p> <p>Most consumers won’t notice a change at the checkout. Companies will need to update their recipes, but even if all the costs of updating recipes were passed on to shoppers, we calculate that at most it would cost about 10 cents each week for the average household.</p> <p>Nor will consumers notice much of a change at the dinner table. <a href="https://www.mdpi.com/2072-6643/6/10/4354">Most people don’t notice</a> when some salt is removed <a href="https://www.sciencedirect.com/science/article/pii/S0022316622031224">from common foods</a>. There are many ways companies can make foods taste just as salty without adding as much salt. For example, they can make <a href="https://www.wsj.com/articles/SB10001424052748704534904575131602283791566">salt crystals finer</a>, or use <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4520464/">potassium-enriched salt</a>, which swaps some of the harmful sodium in salt for potassium. And because the change will be gradual, our tastebuds will <a href="https://doi.org/10.1093/eurjcn/zvac060.077">adapt to less salty foods</a> over time.</p> <h2>Australia’s salt limits are failing</h2> <p>Australia has had voluntary salt limits since 2009, but they are badly designed, poorly implemented, and have reduced population salt intake by just <a href="https://www.abs.gov.au/articles/healthy-food-partnership-reformulation-program-two-year-progress">0.3%</a>.</p> <p>Because Australia’s limits are voluntary, many food companies have chosen not to participate in the scheme. Our analysis shows that 73% of eligible food products are not participating, and only 4% have reduced their salt content.</p> <h2>Action could save lives</h2> <p>Modelling from the University of Melbourne <a href="https://mspgh.unimelb.edu.au/__data/assets/pdf_file/0004/4783405/The-Health-and-Cost-Impacts-of-Sodium-Reduction-Interventions-in-Australia.pdf">shows</a> that fixing our failed salt limits could add 36,000 extra healthy years of life, across the population, over the next 20 years.</p> <p>This would delay more than 300 deaths each year and reduce health-care spending by A$35 million annually, the equivalent of 6,000 hospital visits.</p> <p><a href="https://www.nature.com/articles/jhh2013105">International experience</a> <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.120.16649">shows</a> the costs of implementing such salt limits would be very low and far outweighed by the benefits.</p> <h2>How to fix our failed salt limits</h2> <p>To achieve these gains, the federal government should start by enforcing the limits we already have, by making compliance mandatory. <a href="https://www.sciencedirect.com/science/article/abs/pii/S216183132300042X">Fifteen countries</a> have mandatory salt limits, and 14 are planning to introduce them.</p> <p>The number of foods covered by salt limits in Australia should more than double, to be as broad as those the <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/604338/Salt_reduction_targets_for_2017.pdf">UK set in 2014</a>. Broader targets would include common foods for which Australia does not currently set targets, such as baked beans, butter, margarine and canned vegetables.</p> <p>A loophole in the current scheme that lets companies leave out a fifth of their products should be closed. The federal government should design the policy, rather than doing it jointly with industry representatives.</p> <p>Over the coming decades, Australia will need many new and improved policies to reduce diet-related disease. Reducing salt intake must be part of this agenda. For too long, Australia has let the food industry set the standard, with almost no progress against a major threat to our health.</p> <p>Getting serious about salt would save lives, and it would more than pay for itself through reduced health-care costs and increased economic activity.<!-- Below is The Conversation's page counter tag.

How can I lower my cholesterol? Do supplements work? How about psyllium or probiotics?

<p><em><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> and <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></em></p> <p>Your GP says you have high cholesterol. You’ve six months to work on your diet to see if that’ll bring down your levels, then you’ll review your options.</p> <p>Could taking supplements over this time help?</p> <p>You can’t rely on supplements alone to control your cholesterol. But there’s some good evidence that taking particular supplements, while also eating a healthy diet, can make a difference.</p> <h2>Why are we so worried about cholesterol?</h2> <p>There are two main types of cholesterol, both affecting your risk of heart disease and stroke. Both types are carried in the bloodstream inside molecules called lipoproteins.</p> <p><strong>Low-density lipoprotein or LDL cholesterol</strong></p> <p>This is often called “bad” cholesterol. This lipoprotein carries cholesterol from the liver to cells throughout the body. High levels of LDL cholesterol in the blood can lead to the <a href="https://www.ahajournals.org/doi/full/10.1161/JAHA.118.011433">build-up of plaque</a> in arteries, which leads to an <em>increased</em> risk of heart disease and stroke.</p> <p><strong>High-density lipoprotein or HDL cholesterol</strong></p> <p>This is often called “good” cholesterol. This lipoprotein helps remove excess cholesterol from the bloodstream and transports it back to the liver for processing and excretion. Higher levels of HDL cholesterol are <a href="https://www.ahajournals.org/doi/full/10.1161/CIRCRESAHA.119.312617">linked to</a> a <em>reduced</em> risk of heart disease and stroke.</p> <p>Diet can play a key role in reducing blood cholesterol levels, especially LDL (“bad”) cholesterol. Healthy dietary choices are <a href="https://theconversation.com/got-high-cholesterol-here-are-five-foods-to-eat-and-avoid-63941">well recognised</a>. These include a focus on eating more unsaturated (“healthy”) fat (such as from olive oil or avocado), and eating less saturated (“unhealthy”) fat (such as animal fats) and trans fats (found in some shop-bought biscuits, pies and pizza bases).</p> <h2>Fibre is your friend</h2> <p>An additional way to significantly reduce your total cholesterol and LDL cholesterol levels through diet is by eating more <a href="https://theconversation.com/fiber-is-your-bodys-natural-guide-to-weight-management-rather-than-cutting-carbs-out-of-your-diet-eat-them-in-their-original-fiber-packaging-instead-205159">soluble fibre</a>.</p> <p>This is a type of fibre that dissolves in water to form a gel-like substance in your gut. The gel can bind to cholesterol molecules preventing them from being absorbed into the bloodstream and allows them to be eliminated from the body through your faeces.</p> <p>You can find soluble fibre in whole foods such as fruits, vegetables, oats, barley, beans and lentils.</p> <h2>Fibre supplements, such as psyllium</h2> <p>There are also many fibre supplements and food-based products on the market that may help lower cholesterol. These include:</p> <ul> <li> <p><strong>natural soluble fibres</strong>, such as inulin (for example, Benefiber) or psyllium (for example, Metamucil) or beta-glucan (for example, in ground oats)</p> </li> <li> <p><strong>synthetic soluble fibres</strong>, such as polydextrose (for example, STA-LITE), wheat dextrin (also found in Benefiber) or methylcellulose (such as Citrucel)</p> </li> <li> <p><strong>natural insoluble fibres</strong>, which bulk out your faeces, such as flax seeds.</p> </li> </ul> <p>Most of these supplements come as fibres you add to food or dissolve in water or drinks.</p> <p>Psyllium is the fibre supplement with the strongest evidence to support its use in improving cholesterol levels. It’s been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5413815/">studied</a> in at least 24 high-quality randomised controlled trials.</p> <p>These trials show consuming about 10g of psyllium a day (1 tablespoon), as part of a healthy diet, <a href="https://www.sciencedirect.com/science/article/pii/S0002916523070107#:%7E:text=Conclusions%3A,mild%2Dto%2Dmoderate%20hypercholesterolemia.">can significantly lower</a> total cholesterol levels by 4% and LDL cholesterol levels by 7%.</p> <h2>Probiotics</h2> <p>Other cholesterol-lowering supplements, such as probiotics, are not based on fibre. Probiotics are thought to help lower cholesterol levels via a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3352670/">number of mechanisms</a>. These include helping to incorporate cholesterol into cells, and adjusting the microbiome of the gut to favour elimination of cholesterol via the faeces.</p> <p>Using probiotics to reduce cholesterol is an upcoming area of interest and the <a href="https://www.sciencedirect.com/science/article/abs/pii/S089990071500461X">research</a> is promising.</p> <p>In a <a href="https://pubmed.ncbi.nlm.nih.gov/29384846/">2018 study</a>, researchers pooled results from 32 studies and analysed them altogether in a type of study known as a meta-analysis. The people who took probiotics reduced their total cholesterol level by 13%.</p> <p><a href="https://www.tandfonline.com/doi/full/10.3109/07853890.2015.1071872">Other</a> <a href="https://link.springer.com/article/10.1007/s11906-020-01080-y">systematic reviews</a> support these findings.</p> <p>Most of these studies use probiotics containing <em>Lactobacillus acidophilus</em> and <em>Bifidobacterium lactis</em>, which come in capsules or powders and are consumed daily.</p> <p>Ultimately, probiotics could be worth a try. However, the effects will likely vary according to the probiotic strains used, whether you take the probiotic each day as indicated, as well as your health status and your diet.</p> <h2>Red yeast rice</h2> <p><a href="https://www.nccih.nih.gov/health/red-yeast-rice">Red yeast rice</a> is another non-fibre supplement that has gained attention for lowering cholesterol. It is often used in Asia and some European countries as a complementary therapy. It comes in capsule form and is thought to mimic the role of the cholesterol-lowering medications known as statins.</p> <p>A <a href="https://www.frontiersin.org/articles/10.3389/fphar.2021.819482/full">2022 systematic review</a> analysed data from 15 randomised controlled trials. It found taking red yeast rice supplements (200-4,800mg a day) was more effective for lowering blood fats known as triglycerides but less effective at lowering total cholesterol compared with statins.</p> <p>However, these trials don’t tell us if red yeast rice works and is safe in the long term. The authors also said only one study in the review was registered in a major <a href="https://www.clinicaltrials.gov">database</a> of clinical trials. So we don’t know if the evidence base was complete or biased to only publish studies with positive results.</p> <h2>Diet and supplements may not be enough</h2> <p>Always speak to your GP and dietitian about your plan to take supplements to lower your cholesterol.</p> <p>But remember, dietary changes alone – with or without supplements – might not be enough to lower your cholesterol levels sufficiently. You still need to quit smoking, reduce stress, exercise regularly and get enough sleep. Genetics can also play a role.</p> <p>Even then, depending on your cholesterol levels and other risk factors, you may still be recommended cholesterol-lowering medications, such as <a href="https://jamanetwork.com/journals/jama/fullarticle/2795522">statins</a>. Your GP will discuss your options at your six-month review.<!-- Below is The Conversation's page counter tag.

The top 11 situations to always haggle for a lower price

<p><strong>Mortgage rates</strong></p> <p>Buying a new home is probably the biggest purchase you will make over the course of your life, so every last penny you can save is worth it. “Borrowers should shop their business around to many banks/lenders to see what rates are available,” says mortgage broker Ade Labinjo. “Then use the rates obtained to pit the banks against each other for the purpose of either matching or driving down the rates they were quoted.”</p> <p>Labinjo says that by getting at least one extra quote rate, the average borrower could save up to $1,500. Never settle for the initial quote rate that the bank offers you – haggle for a better price because chances are, they’re not giving you their absolute best offer upfront.</p> <p><strong>Flea markets, farmers markets, garage sales</strong></p> <p>At flea markets, farmers markets, and garage sales the sellers typically set their own price. If you know how to haggle, this is a great opportunity to get a really good deal. Also, see if buying in bulk or large quantities can get you a price reduction.</p> <p><strong>Hotel rooms</strong></p> <p>Hotels want their rooms filled, so it never hurts to haggle with the people at the front desk for a better price or room upgrades. “Hotels have to pay a commission to booking websites, and pass on some of that as a benefit to the user,” says Saurabh Jindal, founder of Talk Travel.</p> <p>If you find that the price is the same on the booking website and the hotel’s website, ask the hotel for a room with a better view or more amenities. “Hotels have rooms allocated to various booking platforms and may give you a better option which has not yet been sold.”</p> <p><strong>Memberships</strong></p> <p>Memberships always come along with extra fees. It might be a renewal fee, startup fee, or a maintenance fee if it’s your gym membership. Ask if they can waive some of the fees or threaten to cancel and go somewhere else. They want to keep making money off of you and might just give you a discount.</p> <p><strong>Lease renewal </strong></p> <p>If you’re considering re-signing your lease, know that it is most likely more expensive for the landlord to prepare your apartment for a new tenant than to lease to you for another year. If you’ve had a good relationship with your landlord, try to negotiate in a deal before you re-sign. If the landlord is going to increase your rent, ask if you can increase it by less or not at all. If you consistently pay rent on time, are a respectful neighbour, and take good care of your apartment they may keep your rent from increasing.</p> <p>It’s important to remember who your lease is with though, says Julie Ramhold, Consumer Expert at DealNews.com. If your apartment is owned by a management company, they probably won’t offer any wiggle room. But, if you’re renting from a single landlord or owner, try negotiating for a lower price.</p> <p><strong>Online selling platforms </strong></p> <p>People who post items for sale online are typically moving or looking to get rid of unwanted items. Use that to your advantage and ask for a lower price – the worst they can say is no. You could also offer to come and pick it up quickly if they give you a better deal.</p> <p><strong>Internet and phone bill</strong></p> <p>As annoying as your internet and phone provider may be, they don’t want to lose you as a customer. “If you’re signing up or looking to renew, sometimes you can get a lower rate by telling a rep what the competitor is offering and saying it works better with your budget,” says Ramhold.</p> <p>A lot of cable companies give you a promotional price for your first year, make sure to call right before the price goes up for your second year. The competitors will most likely offer better prices for new customers and that can work in your advantage and possibly get you a better deal with your current provider.</p> <p><strong>Insurance rates</strong></p> <p>Just like internet providers, insurance companies don’t want you to switch to a different provider. “Use your customer loyalty to your advantage and try to talk to the right person on the phone,” says Kelan Kline a personal finance expert and co-founder of The Savvy Couple. “Tell them the service you are receiving is not good enough for the price.” They might offer you a discount to keep you.</p> <p><strong>Home services</strong></p> <p>If you’re renovating your kitchen or getting some landscaping done, make sure to shop around and get a few different quotes first. Use those quotes to negotiate with the contractor you want to work with. Also, you may be able to haggle for a better price if you offer to pay upfront in cash or schedule a contractor during the winter months when business is typically slower.</p> <p><strong>Jewellery</strong></p> <p>“You should know that the markup on diamond jewellery is anywhere from 50 to 200 per cent and more,” says Chhavi Agarwal, a personal finance expert. There is always room for haggling. Agarwal suggests politely making a counteroffer. You’d be surprised the changes they are willing to make to the bill. If they refuse to come down in price, try to haggle the labour charges.</p> <p><strong>Returned items </strong></p> <p>Never miss an opportunity to haggle for a better price on items that have been returned to stores. Stores will typically mark returned items that have been slightly used or have a ding with a price reduction, but it doesn’t hurt to ask for more off. They know that items that have already been opened aren’t as appealing to customers and they want to get them sold.</p> <p><em>Image credits: Getty Images</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.com.au/food-home-garden/money/11-times-you-should-always-haggle-for-a-better-price?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Climb the stairs, lug the shopping, chase the kids. Incidental vigorous activity linked to lower cancer risks

<p><em><a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Many people know exercise reduces the risk of <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2521826">cancers</a>, including liver, lung, breast and kidney. But structured exercise is time-consuming, requires significant commitment and often financial outlay or travel to a gym. These practicalities can make it infeasible for <a href="https://bjsm.bmj.com/content/42/11/901">most adults</a>.</p> <p>There is <a href="https://www.nature.com/articles/s41591-022-02100-x">very little research</a> on the potential of incidental physical activity for reducing the risk of cancer. Incidental activities can include doing errands on foot, work-related activity or housework as part of daily routines. As such they do not require an extra time commitment, special equipment or any particular practical arrangements.</p> <p>In our <a href="https://jamanetwork.com/journals/jamaoncology/fullarticle/2807734">study</a> out today, we explored the health potential of brief bursts of vigorous physical activities embedded into daily life. These could be short power walks to get to the bus or tram stop, stair climbing, carrying heavy shopping, active housework or energetic play with children.</p> <h2>How was the study done?</h2> <p>Our <a href="https://jamanetwork.com/journals/jamaoncology/fullarticle/2807734">new study</a> included 22,398 <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a> participants who had never been diagnosed with cancer before and did not do any structured exercise in their leisure time. Around 55% of participants were female, with an average age of 62. Participants wore wrist activity trackers for a week. Such trackers monitor activity levels continuously and with a high level of detail throughout the day, allowing us to calculate how hard and exactly for how long people in the study were moving.</p> <p>Participants’ activity and other information was then linked to future cancer registrations and other cancer-related health records for the next 6.7 years. This meant we could estimate the overall risk of cancer by different levels of what we call “<a href="https://pubmed.ncbi.nlm.nih.gov/33108651/">vigorous intermittent lifestyle physical activity</a>”, the incidental bursts of activity in everyday life. We also analysed separately a group of <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2521826">13 cancer sites in the body</a> with more established links to exercise, such such as breast, lung, liver, and bowel cancers.</p> <p>Our analyses took into account other factors that influence cancer risk, such as age, smoking, diet, and alcohol habits.</p> <h2>What we found out</h2> <p>Even though study participants were not doing any structured exercise, about 94% recorded short bursts of <a href="https://pubmed.ncbi.nlm.nih.gov/33108651/">vigorous activity</a>. Some 92% of all bouts were done in very short bursts lasting up to one minute.</p> <p>A minimum of around 3.5 minutes each day was associated with a 17–18% reduction in total cancer risk compared with not doing any such activity.</p> <p>Half the participants did at least 4.5 minutes a day, associated with a 20–21% reduction in total cancer risk.</p> <p>For cancers such as breast, lung and bowel cancers, which we know are impacted by the amount of exercise people do, the results were stronger and the risk reduction sharper. For example, a minimum of 3.5 minutes per a day of vigorous incidental activity reduced the risk of these cancers by 28–29%. At 4.5 minutes a day, these risks were reduced by 31–32%.</p> <p>For both total cancer and those known to be linked to exercise, the results clearly show the benefits of doing day-to-day activities with gusto that makes you huff and puff.</p> <h2>Our study had its limits</h2> <p>The study is observational, meaning we looked at a group of people and their outcomes retrospectively and did not test new interventions. That means it cannot directly explore cause and effect with certainty.</p> <p>However, we took several statistical measures to minimise the possibility those with the lowest levels of activity were not the unhealthiest, and hence the most likely to get cancer – a phenomenon called “<a href="https://www.sciencedirect.com/topics/computer-science/reverse-causation">reverse causation</a>”.</p> <p>Our study can’t explain the biological mechanisms of how vigorous intensity activity may reduce cancer risk. Previous <a href="https://journals.lww.com/acsm-msse/Fulltext/2017/02000/Brief_Intense_Stair_Climbing_Improves.10.aspx">early-stage trials</a> show this type of activity leads to rapid improvements in heart and lung fitness.</p> <p>And higher fitness is linked to lower <a href="https://www.sciencedirect.com/science/article/abs/pii/S0002934320300097">insulin resistance</a> and lower <a href="https://www.sciencedirect.com/science/article/pii/S0735109704017036">chronic inflammation</a>. High levels of these are risk <a href="https://www.sciencedirect.com/science/article/pii/S0735109704017036">factors for cancer</a>.</p> <p>There is very little research on incidental physical activity and cancer in general, because most of the scientific evidence on lifestyle health behaviours and cancer is based on questionnaires. This method doesn’t capture short bursts of activity and is very inaccurate for measuring the incidental activities of daily life.</p> <p>So the field of vigorous intensity activity and cancer risk is at its infancy, despite some <a href="https://academic.oup.com/eurheartj/article/43/46/4801/6771381">very promising</a> recent findings that vigorous activity in short bouts across the week could cut health risks. In another recent study of ours, we found benefits from daily <a href="https://www.nature.com/articles/s41591-022-02100-x%22%22">vigorous intermittent lifestyle activity</a> on the risk of death overall and death from cancer or cardiovascular causes.</p> <h2>In a nutshell: get moving in your daily routine</h2> <p>Our study found 3 to 4 minutes of vigorous incidental activity each day is linked with decreased cancer risk. This is a very small amount of activity compared to <a href="https://bjsm.bmj.com/content/54/24/1451">current recommendations</a> of 150–300 minutes of moderate intensity or 75–150 minutes of vigorous intensity activity a week.</p> <p>Vigorous incidental physical activity is a promising avenue for cancer prevention among people unable or unmotivated to exercise in their leisure time.</p> <p>Our study also highlights the potential of technology. These results are just a glimpse how wearables combined with machine learning – which our study used to identify brief bursts of vigorous activity – can reveal health benefits of unexplored aspects of our lives. The future potential impact of such technologies to prevent cancer and possibly a <a href="https://www.nature.com/articles/s41591-022-02100-x">host of other</a> conditions could be very large.<!-- Below is The Conversation's page counter tag.

This in turn would alter the make-up of the Australian electorate at each election or referendum. The addition of socially progressive voters might well be <a href="https://reporter.anu.edu.au/all-stories/young-people-may-decide-the-outcome-of-the-voice-referendum-heres-why">decisive</a> on a highly contentious and divisive issue such as the Indigenous Voice to Parliament.</p> <h2>Who should have the right to vote?</h2> <p>In 1973, following mass youth casualties in the Vietnam War, Australia’s voting age was lowered from 21 to 18. The reasoning behind this centred on equity: if 18-year-olds were old enough to fight and die, they should be old enough to vote.</p> <p>Today’s equity arguments centre on taxation: many 16 and 17-year-olds pay tax and therefore should have equal rights to representation. However, this representation logic is not <a href="https://www.aph.gov.au/Parliamentary_Business/Committees/Joint/Electoral_Matters/VotingAge/Advisory_report/section?id=committees%2Freportjnt%2F024195%2F26301#:%7E:text=Civics%20education,-2.81&amp;text=Lowering%20the%20voluntary%20voting%20age,for%20politics%20and%20civics%20education.">unique</a> to 16 and 17-year-olds. It applies equally well to those under 16, as well as to tourists and temporary residents, who pay tax but do not have the right to vote.</p> <p>Beyond the taxation argument, the franchise has been aligned with other adult responsibilities such as driving a car and consenting to sex. An important point of distinction, though, is the motivation: do they actually want to vote?</p> <p>Although enthusiastic young leaders are driving campaigns such as Make It 16, we cannot be confident that a subset of politically engaged young people is representative of the Australian youth. There is no question about the cognitive abilities of 16 to 17-year-olds to engage with the electoral process. But there is little longitudinal data to firmly establish that younger people are <a href="https://www.abc.net.au/everyday/do-young-people-care-about-politics/10905604">enthused</a> about voting.</p> <p>That is not to say young people are not <a href="https://theconversation.com/young-australians-are-supposedly-turning-their-backs-on-democracy-but-are-they-any-different-from-older-voters-163891">interested in politics</a>. <a href="https://openresearch-repository.anu.edu.au/bitstream/1885/292274/2/Full%20Thesis%20Revisions_clean%20copy.pdf">Evidence</a> from Australia and elsewhere shows young people engage differently: their engagement with politics is based more on issues than party loyalties.</p> <p>Being able to vote would mean younger people feel less excluded and alienated from politics. However, critics <a href="https://www.news.com.au/national/politics/gen-z-pushing-for-australias-voting-age-to-be-lowered-to-16/news-story/ba9103ed2b5bb825b9178b6efb52a1d9">worry</a> voluntary voting for 16 to 17-year-olds would weaken compulsory voting.</p> <p>Australia’s compulsory voting means it has <a href="https://www.tandfonline.com/doi/full/10.1080/10361146.2021.1899131">resisted</a> youth electoral disengagement at the polls, which has markedly happened in other non-compulsory voting democracies. Given the highly transitory life stage they are in, young people are more likely to abstain if voting is voluntary. This would also run the risk of imprinting the habit of abstention.</p> <h2>What does the evidence suggest?</h2> <p>Data from the Australian Election Study <a href="https://australianelectionstudy.org/wp-content/uploads/McAllister-Voting-Age-2014.pdf">suggest</a> lowering the voting age would not invigorate electoral participation. It is likely early enfranchisement alone <a href="https://www.aph.gov.au/Parliamentary_Business/Committees/Joint/Electoral_Matters/VotingAge/Advisory_report/section?id=committees%2Freportjnt%2F024195%2F26301#footnote28target">will not be a panacea</a> for youth engagement. Rather, there are concerns that voluntary voting might further exacerbate the problem of lower youth enrolment.</p> <p>My <a href="https://openresearch-repository.anu.edu.au/bitstream/1885/292274/2/Full%20Thesis%20Revisions_clean%20copy.pdf">comparative study</a> of youth electoral disengagement in advanced democracies studied a suite of institutional factors, including:</p> <ul> <li>electoral system (majoritarian versus proportional)</li> <li>type of executive (parliamentary/presidential)</li> <li>type of system (federal/unitary)</li> <li>party system (two/multi)</li> <li>voting age (16-21).</li> </ul> <p>I found that, even when controlling for compulsory voting, it is the registration system that significantly influences generational engagement at the polls.</p> <p>Transition to adulthood is characterised by increasing mobility in every aspect of life. On top of this, registration rules make it difficult for young people without a permanent, long-term residence to register to vote.</p> <p>Within the voluntary registration system, young people are especially disadvantaged since new eligible voters are often unfamiliar with the registration system, including how and where to register to vote. Consequently, many confused, eligible voters inadvertently miss voter registration deadlines. Current <a href="https://www.aec.gov.au/Enrolling_to_vote/Enrolment_stats/performance/national-youth.htm">evidence</a> shows voter enrolment is lowest among those aged 18-24, at 89.5%, compared to a <a href="https://www.aec.gov.au/enrolling_to_vote/enrolment_stats/">national figure</a> of 97.2%.</p> <p>However, what has been largely missing in the voting age debate is that lowering it to 16 may be a way to redress this enrolment discrepancy. It may be an institutional design feature that could cater to youth transition: 16-17-year-olds are more likely to be in parental homes when they enrol and then finally vote. This may help attract and keep them as active voters as they gain independence.</p> <h2>What does this mean for (major) parties?</h2> <p>The Coalition’s historic low support among young voters in the <a href="https://australianelectionstudy.org/wp-content/uploads/The-2022-Australian-Federal-Election-Results-from-the-Australian-Election-Study.pdf">2022 federal election</a> may be a symptom of a long-lasting generational shift in the electorate. In the past two elections, only 26% of Gen Z voters, born after 1996, reported voting for the Coalition, while 67% of them voted either for the Greens or Labor. Although historically young people have tended to become more conservative as they age, <a href="https://www.afr.com/politics/millennials-are-getting-older-but-not-more-conservative-20221205-p5c3na">recent evidence</a> suggests voters born after 1980 are not doing that.</p> <p>Extrapolating this trajectory of voting preferences, the addition of more socially progressive, issue-based younger voters will potentially benefit the left-of-centre parties, particularly the Greens. One political reason for Labor’s reluctance to lower the voting age seems to be the stark popularity of the Greens among Gen Z voters, which would increase the Greens threat to the incumbent.</p> <p>Over the years, both major parties have been losing their (youth) votes to the Greens. Lowering the voting age may well pronounce this.</p> <h2>What would it mean for young voters?</h2> <p>Given the context of compulsory voting, Australia is best placed to implement the lowering of voting age to reap the benefits of engaging younger voters to the electorate. Much <a href="https://www.smh.com.au/politics/federal/push-to-follow-overseas-lead-and-lower-voting-age-to-16-gains-momentum-20220401-p5aa3o.html">has been said</a> about how this would improve youth representation, efficacy and outcomes.</p> <p>However, lowering the voting age might not address the problem of <a href="https://www.policyforum.net/overly-suspicious-youth-or-dodgy-politicians/">youth distrust</a> of politicians and the widening gap between younger generations and political parties. This would require a sincere effort to understand what causes the drift, before enfranchising younger voters and loosely tying them to a voluntary voting system. In fact, there is a real risk that voluntary voting might encourage the type of abstention driven by a strong dislike for politicians.</p> <p>Enfranchising hundreds and thousands of additional voters would also inevitably raise the issues of ensuring proper enrolment and that young voters are well informed to vote. It would need to be accompanied by a major boost to <a href="https://theconversation.com/schools-are-not-adequately-preparing-young-australians-to-participate-in-our-democracy-88131">civics education</a> in Australian secondary schools.</p> <p>All in all, while compulsory voting is the best system for lowering the voting age, we’d have to be careful not to undermine the system as it stands. Instead, it is important to tie it to efforts to inform younger voters and reduce the age-related barriers in a (compulsory) electoral process.<!-- Below is The Conversation's page counter tag.

Golfers guide to lower back pain

<p><em><strong>Dr Richard Parkinson is a highly trained neurosurgeon who has performed ground breaking and complex surgery on some of Australia's elite sportspeople and recognised as a leading expert in sports injuries.</strong></em></p> <p>Golf is a great sport for general fitness, including muscular endurance and cardiovascular wellbeing. However, it’s time we talked about golf back pain, which is a fairly common affliction, exacerbated by the more advanced age of the average amateur golfer. Fortunately, the pros of getting out there on the green outweigh the cons.</p> <p>Lower back pain in golfers is common, as are a range of other injuries to areas including the neck, shoulders, elbows, head and eyes. Interestingly enough, injuries to the knees are pretty rare. Golf back pain and neck pain are usually related to bending or twisting injury and both are, in turn, often related to current swinging of the club. Golf is, unfortunately, a fairly asymmetric sport.</p> <p><strong>The price of the swing</strong></p> <p>The problem is that the swinging action causing the pain is unavoidable in golf. You can't hold your back completely still while you swing. Having said that, though, it's not a tremendously high impact sport by any reach of the imagination, and the exercise you get from being outdoors and getting some gentle exercise is very beneficial.</p> <p>So for people who are a bit older, golf remains an excellent way to get some exercise and have some fun. Equally, however, that twisting can increase the problem with lower back pain and really the only thing you can do is, if you're hurting, work on your short game and minimise your swing. Other solutions might be to work on your putt and to try to improve your score by avoiding the big screen with the three wood. Most people can do a short swing with an iron and get three quarters of the way.</p> <p><strong>The core of the problem</strong></p> <p>When I discover lower back pain in golfers, I usually tell them to go and see a physio and get some work done on their core. In the meantime, they can still work on their short game while they gradually find their way back to full strength with the assistance of a physio. Core strength is the key to avoiding golf back pain. Golfers need to learn how to turn their core on—to engage it, in other words—when they swing, and to start approaching their game in a physiological way with a bit of knowledge about how their body works.</p> <p>There are a lot of golfers out there, and it is, generally speaking, a low-risk game for injuries—but what if you have an established back problem or disc herniation, what should you do about your golf? After I perform disc surgery, I usually tell patients to have three months off golf, because the twisting can predispose you to golf back pain.</p> <p><strong>Your first step</strong></p> <p>If you do have an injury, it's always worthwhile giving it some physiotherapy and, as a Sydney neurosurgeon, I can definitely refer my patients to a physio with an interest in golfing injuries.</p> <p>There are physios out there that specialise in asymmetric sports; then there are those that specialise in over-arm sports − and there are those physios that specialise in bending and twisting type sports.</p> <p><em>Images: Getty</em></p>

6 stretches for lower back pain

<h2>Lower back pain 101</h2> <p>Low back pain is a beast. And not just because it can make you feel like your body is rebelling against you. Back pain can is a symptom of a problem. To treat the symptom – with things like stretches for lower back pain – you have to know what the problem is.</p> <p>This becomes complicated because the cause of low back pain is sometimes hard to pin down. Sometimes it’s obvious. You pick up a heavy box without thinking about proper lifting form and – bam! – you pull a muscle and end up with an acute bout of pain. But other times, the problem is more insidious and unclear.</p> <p>Maybe after years of inactivity, you’ve felt pain starting to creep in, possibly due to changes in muscle balance, decreases in strength, and general inflammation. Maybe you injured yourself years ago and, over time, a minor injury exacerbated it into something more serious.</p> <h2>Here’s why stretching could help lower back pain</h2> <p>That doesn’t mean you have to live with the pain. Movement (you know, exercise) is one of the best ways to prevent, limit, and address back pain.</p> <p>“Most of us aren’t moving in the variety of ways our bodies are built for, and habitual postures and sedentary living create excessive muscular tension, which leads to discomfort,” says Lara Heimann, a licensed physical therapist and yoga instructor. “Our bodies signal to us ‘please move!’ But we often ignore the signals and instead adapt to not listening. Over time, we lose some of the innate brain signallings that would otherwise keep us healthy and mobile.”</p> <p>The answer, then, is to move more. You need a well-rounded exercise program that includes back pain exercises, as well as cardiovascular and muscle-strengthening exercises. Incorporating flexibility and stretching exercises can also help you attain and maintain the range of motion you need to help keep pain at bay.</p> <p>“Taking time to stretch helps decrease stiffness, reduces pain and discomfort, and reprograms our brains to send signals when we need to get up and stretch,” Heimann says.</p> <p>Regular stretching can also facilitate better circulation, allowing for more efficient transportation of oxygen and nutrient-rich blood throughout the body, says Heimann.</p> <p>But most importantly, Heimann stresses that stretching is a preservation tool for movement, helping prevent tightness and tension that can set the stage for injuries. “Regular stretching helps to preserve joint health,” Heimann says. “The joint can move freely and efficiently in all directions with decreased stress placed on its structures.”</p> <h2>Word of caution</h2> <p>Back pain has so many causes and some are more serious than others. If your back pain persists for more than a few days, or if it’s severe or causes weakness or tingling in your extremities, make an appointment to see your doctor. Also, avoid any stretch or exercise that causes sharp or shooting pain. Not all types of stretches or exercises are appropriate for every person or every injury. This is why extended self-treatment isn’t advised. To address an issue effectively, you need to know exactly what the issue is.</p> <h2>Warm up</h2> <p>You know how you feel a little more tight first thing in the morning or after sitting still for a few hours? While stretching is a good way to “wake up” your muscles and joints after remaining stationary, you’ll feel better all-around if you’ve gotten your blood pumping a little bit first. And you’ll likely move more smoothly and comfortably through a full range of motion as you stretch.</p> <p>This is because circulating blood delivers oxygen and nutrients to your working muscles, helps warm them up, and prepares them for whatever movements you’re about to ask of them.</p> <p>Walking briskly or marching in place for a few minutes before you dive in is a good way to help prep your body for your stretching routine. For each of the exercises below, an exercise mat is recommended.</p> <h2>Cat-Cow</h2> <p>For those with back pain, cat-cow – an exercise that is popular in yoga – is a good, active stretch that takes the spine through flexion and extension. According to Heimann, it can help improve posture. Plus, it’s one of the best stretches to do for morning back pain relief.</p> <h3>How to do Cat-Cow</h3> <p>Start on your hands and knees on the floor in a “tabletop” position (back flat, knees under your hips, palms under your shoulders). In a controlled action, press your tailbone up and slowly extend your spine by allowing your abdomen to release toward the floor as you press your chest and shoulders up. You should create a U-shaped curve in your back as you look up toward the ceiling. Think about moving each vertebra separately in a wave-like fashion as you create the extension.</p> <p>Hold for a second, then reverse the action. This time, release your head and neck toward the floor as you flex your spine, ultimately tucking your tailbone under to create a rainbow-like arc with your spine.</p> <p>The first position is “cat,” and the second position is “cow.” As you move into cat, inhale; as you move into cow, exhale. Continue alternating between the two positions for a total of 30 to 60 seconds to help release tension in the back.</p> <h2>Prone Press-up</h2> <p>The Prone Press-up is sometimes called the cobra pose in yoga. But it’s also an essential part of the McKenzie Method that physical therapists and other clinicians often use to help address back pain. While people with low back pain might assume that back flexion (stretches like forward bends to touch the toes) should be used to help loosen up tight hamstrings, hips, and low back, the research actually suggests otherwise. Many people with low back pain are better served by doing back extension exercises, like the prone press-up.</p> <p>“Through clinical observation and research, we have seen that moving into the direction of lumbar spine extension can make a tremendous difference in many people with low back pain,” says chiropractor Jordan Duncan.</p> <p>“One reason for the great benefit of moving into spinal extension is likely due to the fact that as a society we spend the bulk of our time in flexion and very little time in extension,” he says. “Therefore, in the majority of people, spinal extension allows us to undo the effects of a great deal of time spent in flexion.”</p> <h3>How to do Prone Press-up</h3> <p>Lie on your stomach with your palms flat on the mat at your shoulders, as if you were going to do a pushup. Keeping your legs and hips on the floor, press through your palms and lift your chest from the mat, aiming to fully extend your elbows as you try to achieve full extension through your spine. Hold for one or two seconds, then slowly reverse the movement and lower your chest back to the floor.</p> <p>Continue repeating the exercise in a controlled fashion for 30 to 60 seconds. If you can’t reach full extension without pain or irritation, move to the range of motion you can comfortably achieve. As an alternative, press up to a partial extension balanced on your elbows.</p> <h2>Standing Backbend</h2> <p>If the Prone Press-up is simply not doable, the Standing Backbend is another option for achieving back extension. This can be particularly helpful if you experience localised pain while sitting, says physical therapist Sara Mikulsky. “When we spend long hours sitting, our core muscles can weaken and our hip flexors can tighten,” she says. “This then puts abnormal strain on the spine and its structure, which can lead to pain.”</p> <h3>How to do Standing Backbend</h3> <p>Stand tall with your feet roughly hip-distance apart and your knees very slightly bent. Place your hands on the back of your hips. Engage your core and gently lean back. Don’t overdo it, but do allow your shoulders to open and your chest to lift up toward the ceiling. Hold for a few seconds, then carefully return to the starting position. Repeat for 30 to 60 seconds.</p> <h2>Kneeling Hip Flexor</h2> <p>The Standing Backbend can help stretch the hip flexors while also releasing tension in the lumbar spine. You can also specifically target your hip flexors to help loosen them up with a Kneeling Hip Flexor.</p> <h3>How to do Kneeling Hip Flexor</h3> <p>Start on your knees, your hips extended and your torso tall. Place your right foot on the floor in front of you, with your right knee bent at a 90-degree angle (as if you’re about to propose). Place your hands on your hips and shift your weight forward without leaning your torso forward as you press and more fully extend your left hip flexor.</p> <p>You should feel the stretch at the front of your left hip. Hold for a second, release the stretch, then repeat. Continue for 30 to 60 seconds, then switch legs.</p> <h2>Supine Figure 4 Stretch</h2> <p>If you tend to have pain that travels down your leg, the best stretches might differ. Mikulsky points out that this form of pain may be caused by a nerve or disc injury that requires further medical attention. However, stretches – like the Supine Figure 4 stretch – that target a deep muscle in your buttocks called the piriformis, might provide some lower back pain relief (although they’re unlikely to fix the underlying problem).</p> <h3>How to do Supine Figure 4 Stretch</h3> <p>Lie on your back with your knees bent and your feet flat on the floor. Lift your right foot from the floor and place your ankle across your left thigh. Allow your right knee to open outward, creating a “4” shape with your legs. You should feel a stretch through the outside of your hip.</p> <p>Holding this position, reach your hands behind your left thigh and use your hands to guide your left knee closer to your chest. Lift your left foot from the floor to deepen the stretch through your right buttock and hip. Hold for a few seconds, then release your left foot to the floor. Repeat for 30 to 60 seconds before switching sides.</p> <h2>Knee to Chest</h2> <p>If you tend to have back pain while standing, Mikulsky says this might a joint issue or arthritis. If this is the case, a back extension might actually place more stress on your spine, leading to pain. (This is the tricky part about back issues – the stretches that are most appropriate for one issue might be the least appropriate for another.) If you find that standing or attempting back extension stretches – like the Standing Backbend or the Prone Press-up – cause more irritation or pain, try the Knee to Chest exercise.</p> <h3>How to do Knee to Chest</h3> <p>Lie on your back with your legs bent and feet on the floor. Place your hands on the back of each thigh and use your hands to guide your knees toward your chest. Place your hands on your shins and gently pull your knees even closer. You should feel the stretch across your lower back. Hold for 30 seconds to a minute, then repeat two or three times.</p> <p><em>Images: Getty</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/fitness/6-stretches-for-lower-back-pain" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Beat lower back pain

<p>Muscle strain, twinges, aches. These are the common problems associated with pesky lower back pain. Here are some effective ways to reduce your risk of developing a chronic condition.</p> <p>Between 70 to 80 per cent of people will experience back pain at some point in their lives with weight, posture, activity and footwear all common triggers.</p> <p>When you sit, lift, carry things or even cook, you probably don’t consciously think about your back, even though it’s the support structure to your head, neck, shoulders, arms, pelvis and rib cage.</p> <p>Holding in place about 30 bones – or vertebrae – that are cushioned by spongy discs attached to muscles, tendons and ligaments, your back houses your spinal column that keeps your upright. Over time, injury-related issues or constant strain can lead to annoying twinges, chronic aches or pain that interferes with everyday life.</p> <p><strong>Stand up straight</strong></p> <p>Train yourself to become aware of your posture throughout the day. From sitting to standing, there are techniques to improve your stance. For standing, keep your weight evenly balanced between both feet and your shoulders back without straining them. When you’re sitting, again keep your shoulders back in line with your hips with you feet flat on the floor. You can also try a foot stool if that’s more comfortable.</p> <p><strong>Lighten the load</strong></p> <p>Reduce what you carry – meaning you should not be lugging around heavy handbags or backpacks. These will not only strain your muscles but they can also contribute to slumped posture and cause lower back pain if the things you carry are too heavy. Consider getting groceries delivered or asking a family member for help.</p> <p><strong>Lower the heel</strong></p> <p>Ladies, unfortunately it’s not good news. High heels tilt your pelvis forward throwing your centre gravity out of alignment, which in turn forces your back muscles to work harder to maintain stability. Opt for a flat wide heel that’s no higher than 2.5cm – especially if you already suffer lower back pain. Gentlemen who suffer from lower back pain, you should avoid thongs and loafers – both don’t provide the necessary support.</p> <p><strong>Fighting fit</strong></p> <p>Studies show that people who regularly exercise suffer less back pain. But choose your exercise wisely, especially if you already experience some lower back pain. For example swimming will be much better than running in not exacerbating any pain as swimming supports your back as you exercise. Aerobics, yoga and Pilates under the guidance of an experience teacher can also be great for back pain.</p>

Big study shows that lowering blood pressure lowers risk of dementia

<p>A study across 20 countries has strengthened a link between lowering blood pressure, and reducing the risk of dementia.</p> <p>The meta-analysis, published in the European Heart Journal, draws on clinical trial data from 28,008 participants, to show the strongest link to date between medication that lowers blood pressure, and reduced dementia risk.</p> <p>“We know that high blood pressure is a risk factor for dementia – especially high blood pressure in midlife, so say 40 to 65 years of age,” says lead author Dr Ruth Peters, an associate professor at the University of New South Wales and program lead for dementia in the George Institute’s Global Brain Health Initiative.</p> <p>“But there has been some uncertainty about whether lowering blood pressure, especially in older adults, would reduce risk of dementia.</p> <p>“What we’ve done is take five really high-quality clinical trials and combine them into one dataset, which gave us the ability to really look at this question and look at the relationship between blood pressure-lowering tablets – antihypertensives – and dementia.”</p> <p>The five studies were all double-blind, randomised clinical trials – the ‘gold standard’ in medical research – with participants hailing from 20 different countries.</p> <p>The average age of the participants was 69, and participants were followed up an average of four years after doing the trial.</p> <p>Participants who took antihypertensives had a significantly lower chance of being diagnosed with dementia than those who took placebos.</p> <p>Dementia affects 50 million people worldwide: a number projected to triple by 2050.</p> <p>According to The Lancet’s 2020 Commission on dementia, treatment for hypertension (high blood pressure) is “the only known effective preventive medication for dementia,” all other methods of reducing your risk come from lifestyle and environment.</p> <p>“The strength of this study is the use of individual patient data in a meta-analysis of data drawn from randomised controlled trials of blood pressure medication. This is the first time such data has been meta-analysed,” says Professor Kaarin Anstey, a senior principal research scientist at Neuroscience Research Australia and the UNSW.</p> <p>“This is important for informing clinical practice,” adds Anstey, who was not involved with the study.</p> <p>Professor Nicolas Cherbuin, head of the Australian National University’s Centre for Research on Ageing, Health and Wellbeing, says that the study is “well-designed”, and reflects research by his team showing that higher blood pressure is linked to lower brain volumes and poorer brain health.</p> <p>“The diagnostic procedure and criteria used are well-established, the sample size is large, those with dementia at baseline were excluded,” says Cherbuin.</p> <p>But he points out that the study didn’t find an effect of blood pressure medication on cognitive decline, and nor did it include participants with mild cognitive impairment, who would be “more likely to convert”.</p> <p>Anstey points out that “inevitably” the participants in the cohort are now quite old, and thus may be different to populations developing dementia now.</p> <p>“Clinical trials involve highly selected samples and often exclude diverse ethnic groups,” she adds.</p> <p>“I hope that this reinforces the importance of blood pressure control for brain health,” says Peters.</p> <p>But she emphasises that, while this is useful news for preventing dementia in mid-life, people of all ages can improve their brain health by other means.</p> <p>“It’s not just blood pressure lowering – it has to be taken in the context of a healthy lifestyle.”</p> <p><strong>This article originally appeared on <a href="https://cosmosmagazine.com/health/dementia-blood-pressure-meta/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Ellen Phiddian.</strong></p> <p><em>Image: Shutterstock</em></p>

9 natural ways to lower cholesterol

<h2>What is cholesterol?</h2> <p>Cholesterol is a waxy, fat-like substance that is made in your liver and travels throughout your bloodstream. It may not sound particularly good for your body, what with the “waxy” and “fat-like” descriptors, but cholesterol does have some merit.</p> <p>It’s one of the ingredients the body needs to make new cells. And it’s essential for creating vitamin D, bile acids, and hormones such as progesterone and oestrogen.</p> <p>But having too much cholesterol can put you at risk for cardiovascular disease and stroke. That’s why it’s so important you know your level and, if it’s high, take action. These nine lifestyle tips will help you control your cholesterol naturally.</p> <h2>It takes a multifaceted approach</h2> <p>Lowering cholesterol takes a multifaceted approach. It’s not enough to switch from donuts to oatmeal for breakfast or swap out butter for olive oil.</p> <p>Slashing high cholesterol numbers requires you to make healthy lifestyle choices daily. That means looking at all aspects of your routine, from what you eat, to the activity you get, to bad habits you have.</p> <p>One word of warning: if you’re currently taking medication, this isn’t a time to go cold turkey. Stay with your current medication dosage and schedule.</p> <h2>Get plenty of soluble fibre</h2> <p>Fibre comes in two types: soluble and insoluble. Both types are an essential part of a healthy diet. But studies show that soluble fibre, found in high-fibre foods like whole grains, fruits, vegetables, seeds and legumes, can reduce LDL cholesterol by 5 to 10 per cent.</p> <p>Soluble fibres dissolve in water and other bodily fluids. They don’t stick around long, escorting cholesterol to the toilet, so to speak. “Soluble fibre binds to cholesterol in the intestines and causes the cholesterol to be excreted in the stool,” says Dr Colleen Tewksbury, a senior research investigator and bariatric program manager at Penn Medicine in Philadelphia.</p> <p>Insoluble fibre, on the other hand, absorbs water and other materials to form regular stools. You need both types, so be sure you get half of each, totalling about 25 to 30 grams per day.</p> <h2>Eat unsaturated fats</h2> <p>By now, we know that we should limit saturated fats in our diets because it raises levels of bad cholesterol in the blood. But in addition to that, we should also be upping our intake of monounsaturated and polyunsaturated fats.</p> <p>The unsaturated fats from foods like fatty fish, olive oil, vegetables, nuts and seeds are much healthier for the heart.</p> <p>Case in point: a study in the Journal of the Academy of Nutrition and Dietetics found that diets rich in unsaturated fats can improve overall cholesterol levels. Not only were higher intakes of polyunsaturated fats associated with healthier total cholesterol levels, but higher intakes of monounsaturated fats were linked to healthier HDL levels too. “They improve cholesterol likely by requiring less work and leaving fewer/preferred by products of converting by the liver for transport to your cells,” says Tewksbury. Interestingly, the healthiest high-fat foods you should be eating may surprise you. Eggs, for example, are well known for their high cholesterol, but the truth about eggs is that it’s the saturated fats, not the cholesterol, that causes health problems for most people.</p> <h2>Choose foods that contain plant sterols</h2> <p>Plant sterols (also known as phytosterols) are found in foods such as whole grains, fruits, vegetables, vegetable oil, nuts and legumes. “They directly block the absorption of cholesterol,” Tewksbury says. Research published in 2018 in Nutrients indicates that consuming 1.5 to 3 grams of plant sterols per day could decrease LDL cholesterol levels by as much as 12 per cent. Plant sterols occur in small quantities, so food manufacturers fortify cereal, crackers, orange juice, margarine, and other products with them. Then they market the products as “heart healthy,” says Tewksbury. That means some of these so-called “heart healthy” foods are also loaded with saturated fat and sugar. Be sure to check the label and leave the ones high in saturated fat and sugar on the supermarket shelf.</p> <h2>Sprinkle on spices to flavour food</h2> <p>Isn’t it a pleasant surprise to know something you’re probably already eating could help lower cholesterol? Well there’s a good chance you’re already ticking off this cholesterol to-do, at least to some degree. Sprinkling cinnamon in your coffee or oatmeal and cooking with garlic are probably things you’re already doing – without realising they could improve your cholesterol. “Studies suggest consuming certain spices, such as cinnamon and garlic, can help lower cholesterol,” says Tewksbury. Garlic has the potential to regulate slightly elevated cholesterol concentrations, while cinnamaldehyde, the active component in cinnamon, improves lipid and glucose metabolism.</p> <h2>Try a plant-based diet</h2> <p>To bring those high cholesterol numbers down, you might want to consider transitioning to a plant-based diet. “There is a plethora of literature supporting the use of a plant-based diet to treat and reverse multiple chronic diseases, especially heart disease and high cholesterol levels,” says dietitian Dana Hunnes.</p> <p>That likely includes the 2019 ACC/AHA Guidelines on the Primary Prevention of Cardiovascular Disease. The guidelines stated that eating a plant-based protein diet reduced amounts of cholesterol (and sodium) compared with an animal protein diet. Which means replacing animal proteins (think meat and poultry) with plant proteins (like tofu, beans and quinoa) can reduce the risk of plaque build-up in the arteries, a precursor to cardiovascular disease.</p> <h2>Ditch the processed foods</h2> <p>Processed foods are often high in LDL-raising saturated fat. But they come with an additional warning. The trans fats, refined sugars and carbohydrates in processed foods trigger inflammation in the body, says cardiologist Dr Neel Chokshi. “High cholesterol, in combination with inflammation, is what leads to atherosclerosis, or blockages in the walls of your arteries,” he says.</p> <h2>Exercise</h2> <p>You may not know this, but exercise ranks nearly as important as the food you eat when it comes to lowering cholesterol naturally. A huge body of research shows exercise reduces the unhealthy fats circulating in your blood – both LDL and triglycerides. “Cholesterol and fats provide fuel for your body,” Dr Chokshi says. “Exercise raises your body’s energy expenditure and, in turn, burns more of these fats.” Despite the evidence, exercise is rarely the favoured option to lower cholesterol. Some people may think it’s boring, unpleasant, or hard to squeeze into a busy schedule. But that’s not the case – you don’t have to grudgingly drag yourself to the gym in order to reap benefits. “All activity counts as exercise, so choose something you enjoy,” says Dr Chokshi. Better yet, grab some friends or family for fun and accountability. The key to lowering cholesterol is consistency. “We recommend at least 150 minutes of moderate-intensity activity per week, or 75 minutes of high-intensity activity per week,” he says. Beginners can start by walking 30 minutes a day at a comfortable pace, and then build to moderate-intensity activity. Doing two, 20-minute resistance training sessions a week can also help lower cholesterol by increasing muscle mass and raising your metabolism, Dr Chokshi adds.</p> <h2>Shed some weight</h2> <p>If you’re overweight or obese, aim to drop some kilos. Even a little weight loss goes a long way towards achieving lower cholesterol. Research in Translational Behavioral Medicine found that people who lost 5 to 10 per cent of their weight showed a reduction in total cholesterol, LDL and triglycerides. And the numbers got even better when people lost more than 10 per cent. Losing weight will lower your cholesterol and decrease your risks for diabetes and cardiovascular diseases.</p> <h2>Quit smoking</h2> <p>The association between smoking and cholesterol is twofold. For starters, smoking makes LDL cholesterol stickier, so it clings to artery walls. As we know, clogged arteries hinder blood flow and can lead to heart problems. Secondly, smoking lowers HDL cholesterol. That isn’t good because the job of HDL is to escort LDL out of the arteries. Quitting can make a big difference. A review of studies found that HDL levels increase by as much as 30 per cent just after three weeks of stopping smoking. As strong as the argument to quit smoking is, it’s rarely easy to do.</p> <p><strong>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/9-natural-ways-to-lower-cholesterol?pages=1" target="_blank" rel="noopener">Reader's Digest</a>.</strong></p> <p>Image: Shutterstock</p>
