Vitamin D is essential for bone health, immune function and overall wellbeing. And it becomes even more crucial as we age.

New guidelines from the international Endocrine Society recommend people aged 75 and over should consider taking vitamin D supplements.

But why is vitamin D so important for older adults? And how much should they take?

Young people get most vitamin D from the sun

In Australia, it is possible for most people under 75 to get enough vitamin D from the sun throughout the year. For those who live in the top half of Australia – and for all of us during summer – we only need to have skin exposed to the sun for a few minutes on most days.

The body can only produce a certain amount of vitamin D at a time. So staying in the sun any longer than needed is not going to help increase your vitamin D levels, while it will increase your risk of skin cancer.

But it’s difficult for people aged over 75 to get enough vitamin D from a few minutes of sunshine, so the Endocrine Society recommends people get 800 IU (international units) of vitamin D a day from food or supplements.

Why you need more as you age

This is higher than the recommendation for younger adults, reflecting the increased needs and reduced ability of older bodies to produce and absorb vitamin D.

Overall, older adults also tend to have less exposure to sunlight, which is the primary source of natural vitamin D production. Older adults may spend more time indoors and wear more clothing when outdoors.

As we age, our skin also becomes less efficient at synthesising vitamin D from sunlight.

The kidneys and the liver, which help convert vitamin D into its active form, also lose some of their efficiency with age. This makes it harder for the body to maintain adequate levels of the vitamin.

All of this combined means older adults need more vitamin D.

Deficiency is common in older adults

Despite their higher needs for vitamin D, people over 75 may not get enough of it.

Studies have shown one in five older adults in Australia have vitamin D deficiency.

In higher-latitude parts of the world, such as the United Kingdom, almost half don’t reach sufficient levels.

This increased risk of deficiency is partly due to lifestyle factors, such as spending less time outdoors and insufficient dietary intakes of vitamin D.

It’s difficult to get enough vitamin D from food alone. Oily fish, eggs and some mushrooms are good sources of vitamin D, but few other foods contain much of the vitamin. While foods can be fortified with the vitamin D (margarine, some milk and cereals), these may not be readily available or be consumed in sufficient amounts to make a difference.

In some countries such as the United States, most of the dietary vitamin D comes from fortified products. However, in Australia, dietary intakes of vitamin D are typically very low because only a few foods are fortified with it.

Why vitamin D is so important as we age

Vitamin D helps the body absorb calcium, which is essential for maintaining bone density and strength. As we age, our bones become more fragile, increasing the risk of fractures and conditions like osteoporosis.

Keeping bones healthy is crucial. Studies have shown older people hospitalised with hip fractures are 3.5 times more likely to die in the next 12 months compared to people who aren’t injured.

Vitamin D may also help lower the risk of respiratory infections, which can be more serious in this age group.

There is also emerging evidence for other potential benefits, including better brain health. However, this requires more research.

According to the society’s systematic review, which summarises evidence from randomised controlled trials of vitamin D supplementation in humans, there is moderate evidence to suggest vitamin D supplementation can lower the risk of premature death.

The society estimates supplements can prevent six deaths per 1,000 people. When considering the uncertainty in the available evidence, the actual number could range from as many as 11 fewer deaths to no benefit at all.

Should we get our vitamin D levels tested?

The Endocrine Society’s guidelines suggest routine blood tests to measure vitamin D levels are not necessary for most healthy people over 75.

There is no clear evidence that regular testing provides significant benefits, unless the person has a specific medical condition that affects vitamin D metabolism, such as kidney disease or certain bone disorders.

Routine testing can also be expensive and inconvenient.

In most cases, the recommended approach to over-75s is to consider a daily supplement, without the need for testing.

You can also try to boost your vitamin D by adding fortified foods to your diet, which might lower the dose you need from supplementation.

Even if you’re getting a few minutes of sunlight a day, a daily vitamin D is still recommended.

  • Holistic Approach To Resculpting A Face Affected By Hypothyroidism, PCOS, Or Menopause

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Mila Magnani has PCOS and hypothyroidism, but the principles are the same for menopause because both menopause and PCOS are a case of a hormone imbalance resulting in androgenic effects, so there’s a large amount of overlap.

    Obviously, a portion of the difference in the thumbnail is a matter of angle and make-up, but as you can see in the video itself, there’s also a lot of genuine change underneath, too:

    Stress-free method

    Firstly, she bids us get lab tests and work with a knowledgeable doctor to address potential thyroid, hormonal, or nutrient imbalances. Perhaps we already know at least part of what is causing our problems, but even if so, it doesn’t hurt to take steps to rule the others out. Imagine spending ages unsuccessfully battling PCOS or menopause, only to discover it was a thyroid issue, and you were fighting the wrong battle!

    Magnani used a natural route to manage her PCOS and hypothyroidism, while acknowledging that medication is fine too; it’s usually cheaper and more convenient—and there’s a lot more standardization for medications than there is for supplements, which makes it a lot easier to navigate, find what works, and keep getting the exact same thing once it does work.

    Other things she recommends include:

    • Lymphatic drainage: addressing the lymphatic system to reduce puffiness. Techniques include lymphatic drainage massage, stretching, rebounding (trampoline), and dry brushing. She emphasizes that for facial de-puffing, it’s important to treat the whole upper body, not just the face.
    • Low-impact exercise: she switched from high-intensity workouts to low-impact exercises like nature walking and gentle stretching to reduce stress and improve health.
    • Nervous system regulation: she worked on nervous system regulation by means of journaling, breathwork, and stimulating the vagus nerve, which improved sleep and reduced stress and anxiety. These things, of course, have knock-on benefits for almost every part of health.
    • Diet: she adopted a low-glycemic diet, reduced salt intake, and cooked at home to avoid water retention caused by high sodium in restaurant meals.
    • Natural diuretics: she uses teas like hibiscus and chamomile to reduce puffiness after consuming high-sodium foods.
    • Sauna and sweating: consider a sauna mat or hot baths to detox and reduce swelling; that’s what she uses in lieu of a convenient sauna.

    You may be wondering how quickly you can expect results: it took 3–6 months of daily effort to see significant changes, and she now maintains the routine less frequently (every 2–3 days, instead of daily).

  • Neuroaffirming care values the strengths and differences of autistic people, those with ADHD or other profiles. Here’s how

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    We’ve come a long way in terms of understanding that everyone thinks, interacts and experiences the world differently. In the past, autistic people, people with attention deficit hyperactive disorder (ADHD) and other profiles were categorised by what they struggled with or couldn’t do.

    The concept of neurodiversity, developed by autistic activists in the 1990s, is an emerging area. It promotes the idea that different brains (“neurotypes”) are part of the natural variation of being human – just like “biodiversity” – and they are vital for our survival.

    This idea is now being applied to research and to care. At the heart of the National Autism Strategy, currently in development, is neurodiversity-affirming (neuroaffirming) care and practice. But what does this look like?

    Reframing differences

    Neurodiversity challenges the traditional medical model of disability, which views neurological differences solely through a lens of deficits and disorders to be treated or cured.

    Instead, it reframes it as a different, and equally valuable, way of experiencing and navigating the world. It emphasises the need for brains that are different from what society considers “neurotypical”, based on averages and expectations. The term “neurodivergent” is applied to Autistic people, those with ADHD, dyslexia and other profiles.

    Neuroaffirming care can take many forms depending on each person’s needs and context. It involves accepting and valuing different ways of thinking, learning and experiencing the world. Rather than trying to “fix” or change neurodivergent people to fit into a narrow idea of what’s considered “normal” or “better”, neuroaffirming care takes a person-centered, strengths-based approach. It aims to empower and support unique needs and strengths.

    Adaptation and strengths

    Drawing on the social model of disability, neuroaffirming care acknowledges there is often disability associated with being different, especially in a world not designed for neurodivergent people. This shift focuses away from the person having to adapt towards improving the person-environment fit.

    This can include providing accommodations and adapting environments to make them more accessible. More importantly, it promotes “thriving” through greater participation in society and meaningful activities.

    At school, at work, in clinic

    In educational settings, this might involve using universal design for learning that benefits all learners.

    For example, using systematic synthetic phonics to teach reading and spelling for students with dyslexia can benefit all students. It also could mean incorporating augmentative and alternative communication, such as speech-generating devices, into the classroom.

    Teachers might allow extra time for tasks, or allow stimming (repetitive movements or noises) for self-regulation and breaks when needed.

    In therapy settings, neuroaffirming care may mean a therapist grows their understanding of autistic culture and learns about how positive social identity can impact self-esteem and wellbeing.

    They may make efforts to bridge the gap in communication between different neurotypes, known as the double empathy problem. For example, the therapist may avoid relying on body language or facial expressions (often different in autistic people) to interpret how a client is feeling, instead of listening carefully to what the client says.

    Affirming therapy approaches with children involve “tuning into” their preferred way of communicating, playing and engaging. This can bring meaningful connection rather than compliance to “neurotypical” ways of playing and relating.

    In workplaces, it can involve flexible working arrangements (hours, patterns and locations), allowing different modes of communication (such as written rather than phone calls) and low-sensory workspaces (for example, low-lighting, low-noise office spaces).

    In public spaces, it can look like providing a “sensory space”, such as at large concerts, where neurodivergent people can take a break and self-regulate if needed. And staff can be trained to recognise, better understand and assist with hidden disabilities.

    Combining lived experience and good practice

    Care is neuroaffirmative when it centres “lived experience” in its design and delivery, and positions people with disability as experts.

    As a result of being “different”, people in the neurodivergent community experience high rates of bullying and abuse. So neuroaffirming care should be combined with a trauma-informed approach, which acknowledges the need to understand a person’s life experiences to provide effective care.

    Culturally responsive care acknowledges limited access to support for culturally and racially marginalised Autistic people and higher rates of LGBTQIA+ identification in the neurodivergent community.

    Authentic selves

    The draft National Autism Strategy promotes awareness that our population is neurodiverse. It hopes to foster a more inclusive and understanding society.

    It emphasises the societal and public health responsibilities for supporting neurodivergent people via public education, training, policy and legislation. By providing spaces and places where neurodivergent people can be their authentic, unmasked selves, we are laying the foundations for feeling seen, valued, safe and, ultimately, happy and thriving.

  • Walnuts vs Cashews – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing walnuts to cashews, we picked the walnuts.

    Why?

    It was close! In terms of macros, walnuts have about 2x the fiber, while cashews have slightly more protein. In the specific category of fats, walnuts have more fat. Looking further into it: walnuts’ fats are mostly polyunsaturated, while cashews’ fats are mostly monounsaturated, both of which are considered healthy.

    Notwithstanding being both high in calories, neither nut is associated with weight gain—largely because of their low glycemic indices (of which, walnuts enjoy the slightly lower GI, but both are low-GI foods)

    When it comes to vitamins, walnuts have more of vitamins A, B2, B3 B6, B9, and C, while cashews have more of vitamins B1, B5, E, and K. Because of the variation in their respective margins of difference, this is at best a moderate victory for walnuts, though.

    In the category of minerals, cashews get their day, as walnuts have more calcium and manganese, while cashews have more copper, iron, magnesium, phosphorus, potassium, selenium, and zinc.

    In short: unless you’re allergic, we recommend enjoying both of these nuts (and others) for a full range of benefits. However, if you’re going to pick one, walnuts win the day.

    Busting The Myth of “Eight Glasses Of Water A Day”

    Everyone knows we must drink 8 glasses of water a day, or else we’re going to get a failing grade at being a healthy human—like not flossing, or not using adequate sunscreen.

    But… Do we? And does tea count? How about (we dare but whisper it) coffee? And soda drinks are mostly water, right? But aren’t some drinks dehydrating? Are special electrolyte drinks really better? There are so many things to consider, so many differing advices, and it’s easy to give up, or just choose what to believe in as a leap of faith.

    A quick brain-teaser for you first, though:

    If coffee and soda don’t count because they’re dehydrating, then what if you were to take:

    – A concentrated tiny cup of espresso, and then a glass of water, would the glass of water count?

    Or (we don’t relish the thought) what if you took a spoonful of soda syrup, and then a glass of water, would the glass of water count?

    If your answer was “yes, it’s a glass of water”, then why would it not count if it were taken all at once (e.g. as an Americano coffee, or a regular soda)?

    If your answer was “yes, but that water might only offset the dehydration caused by the coffee/syrup, so I might only be breaking even”, then you were thinking about this the right way:

    How much water you need depends on many factors that can be affected by what else you are consuming and what else you are doing. Science loves averages, so eight glasses a day may be great if you are of average health, and average body size, in a temperate climate, doing moderate exercise, and so on and so on.

    If you’re not the most average person of all time? You may need to take into account a lot of factors, ranging from what you ate for dinner to how much you perspired during your morning exercises. As you (probably) don’t live in laboratory conditions, this can become an impossible task—and if you missed (or guessed incorrectly) even one factor, the whole calculation will be thrown off. But is there any other way to know?

    What of the infamous pee test? Drink enough to make your urine as clear as possible, and if it’s dark, you’re dehydrated, common wisdom says.

    In reality, however, that tells you not what’s in your body, but rather, what got ejected from your body. If your urine is dark, it might mean you had too little water, but it also could just mean you had the right amount of water but too much sodium, for instance. A study of this was done on athletes, and found no correlation between urine color and actual bodily hydration when measured directly via a blood test.

    So, if we can’t just have an app tell us “drink this many glasses of water”, and we can’t trust urine color, what can we do?

    What we can do is trust that our body comes with (for free!) a wonderful homeostatic system and it will try to correct any imbalances. If you are thirsty, you’re dehydrated. Drink something with plenty of water in, if not plain water.

    But what about special electrolyte drinks? If you need salts, you will crave them. Craving a salty snack? Go for it! Or if you prefer not to snack, do a salt lick test (just put a little salt on your finger, and taste it; if it tastes good, wait a minute or two, and then have a little more, and repeat until it doesn’t).

    Bonus Tip:

    1. Make sure you always have a source of hydration (that you enjoy!) to hand. Maybe it’s chilled water, maybe it’s a pot of tea, maybe it’s a sports drink, it doesn’t matter too much. Even coffee is actually fine, by the way (but don’t overdo it).
    2. Make a personal rule: “I will always make time for hydration”. That means, if you’re thirsty, have something with water in it now. Not when you’ve finished what you’re doing (unless you really can’t stop, because you are a racecar driver mid-race, or a surgeon mid-operation, or something), but now. Do not postpone it until after you’ve done some other thing first; you will forget and it will keep getting postponed. Always make time for water.

  • Top 5 Anti-Aging Exercises

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    There are some exercises that get called such things as “The King of Exercises!”, but how well-earned is that title and could it be that actually a mix of the top few is best?

    The Exercises

    While you don’t have to do all 5, your body will thank you if you are able to:

    • Plank: strengthens most of the body, and can reduce back pain while improving posture.
    • Squats: another core-strengthening exercise, this time with an emphasis on the lower body, which makes for strong foundations (including strong ankles, knees, and hips). Improves circulation also, and what’s good for circulation is good for the organs, including the brain!
    • Push-ups: promotes very functional strength and fitness; great for alternating with planks, as despite their similar appearance, they work the abs and back more, respectively.
    • Lunges: these are great for lower body strength and stability, and doing these greatly reduces the risk of falling.
    • Glute Bridges: this nicely rounds off one’s core strength, increasing stability and improving posture, as well as reducing lower back pain too.

    If the benefits of these seem to overlap a little, it’s because they do! But each does some things that the others don’t, so put together, they make for a very well-balanced workout.

    For advice on how to do each of them, plus more about the muscles being used and the benefits, enjoy:

  • Fruit, Fiber, & Leafy Greens… On A Low-FODMAP Diet!

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Fiber For FODMAP-Avoiders

    First, let’s quickly cover: what are FODMAPs?

    FODMAPs are fermentable oligosaccharides, disaccharides, monosaccharides, and polyols.

    In plainer English: they’re carbohydrates that are resistant to digestion.

    This is, for most people most of the time, a good thing, for example:

    When Is A Fiber Not A Fiber? When It’s A Resistant Starch.

    Not for everyone…

    However, if you have inflammatory bowel syndrome (IBS), including ulcerative colitis, Crohn’s disease, or similar, then suddenly a lot of common dietary advice gets flipped on its head:

    Dietary Intolerances & More

    While digestion-resistant carbohydrates making it to the end parts of our digestive tract are good for our bacteria there, in the case of people with IBS or similar, it can be a bit too good for our bacteria there.

    Which can mean gas (a natural by-product of bacterial respiration) accumulation, discomfort, water retention (as the pseudo-fiber draws water in and keeps it), and other related symptoms, causing discomfort, and potentially disease such as diarrhea.

    Again: for most people this is not so (usually: quite the opposite; resistant starches improve things down there), but for those for whom it’s a thing, it’s a Big Bad Thing™.

    Hold the veg? Hold your horses.

    A common knee-jerk reaction is “I will avoid fruit and veg, then”.

    Superficially, this can work, as many fruit & veg are high in FODMAPs (as are fermented dairy products, by the way).

    However, a diet free from fruit and veg is not going to be healthy in any sustainable fashion.

    There are, however, options for low-FODMAP fruit & veg, such as:

    Fruits: bananas (if not overripe), kiwi, grapefruit, lemons, limes, melons, oranges, passionfruit, strawberries

    Vegetables: alfalfa, bell peppers, bok choy, carrots, celery, cucumbers, eggplant, green beans, kale, lettuce, olives, parsnips, potatoes (and sweet potatoes, yams etc), radishes, spinach, squash, tomatoes*, turnips, zucchini

    *our stance: botanically it’s a fruit, but culinarily it’s a vegetable.

    For more on the science of this, check out:

    Bonus

    Grains: oats, quinoa, rice, tapioca

    …and wheat if the conditions in table 3 (linked above) are satisfied

    (worth mentioning since grains also get a bad press when it comes to IBS, but that’s mostly because of wheat)
