Are you over 75? Here’s what you need to know about vitamin D

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.

  • Treat Your Own Hip – by Robin McKenzie

    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 previously reviewed another book by this author in this series, “Treat Your Own Knee”, and today it’s the same deal, but for the hip.

    A quick note about the author first: a physiotherapist and not a doctor, but with over 40 years of practice to his name and 33 letters after his name (CNZM OBE FCSP (Hon) FNZSP (Hon) Dip MDT Dip MT), he seems to know his stuff.

    He takes the reader through first diagnosing the nature of the pain (and how to rule out, for example, a back problem manifesting as hip pain, rather than a hip problem per se—and points to his own “Treat Your Own Back” manual if it turns out that that’s your problem instead), and then treating it. A bold claim, the kind that many people’s lawyers don’t let them make, but once again, this guy is pretty much the expert when it comes to this. Ask any other physiotherapist, and they probably have several of his books on their shelf.

    The treatments recommend are tailored to the results of various diagnostic flowcharts; essentially troubleshooting your hip. However, they mainly consist of exercises (perhaps the greatest value of the book), and lifestyle adjustments (these ones, 10almonds readers probably know already, but a reminder never hurts).

    The explanations are thorough while still being comprehensible, and there is zero sensationalization or fluff. It is straight to the point, and clearly illustrated too with diagrams and photographs.

    Bottom line: if you’re looking for a “one-stop shop” for diagnosing and treating your bad hip, then this is it.

    Click here to check out Treat Your Own Hip, and indeed Treat Your Own Hip!

    PS: if you have musculoskeletal problems elsewhere in your body, you might want to check out the rest of his body parts series (neck, back, shoulder, wrist, knee, ankle) for the one that’s tailored to your specific problem.

  • The Insider’s Guide To Making Hospital As Comfortable As Possible

    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.

    Nobody Likes Surgery, But Here’s How To Make It Much Less Bad

    This is Dr. Chris Bonney. He’s an anesthesiologist. If you have a surgery, he wants you to go in feeling calm, and make a quick recovery afterwards, with minimal suffering in between.

    Being a patient in a hospital is a bit like being a passenger in an airplane:

    • Almost nobody enjoys the thing itself, but we very much want to get to the other side of the experience.
    • We have limited freedoms and comforts, and small things can make a big difference between misery and tolerability.
    • There are professionals present to look after us, but they are busy and have a lot of other people to tend to too.

    So why is it that there are so many resources available full of “tips for travelers” and so few “tips for hospital patients”?

    Especially given the relative risks of each, and likelihood, or even near-certainty of coming to at least some harm… One would think “tips for patients” would be more in demand!

    Tips for surgery patients, from an insider expert

    First, he advises us: empower yourself.

    Empowering yourself in this context means:

    • Relax—doctors really want you to feel better, quickly. They’re on your side.
    • Research—knowledge is power, so research the procedure (and its risks!). Dr. Bonney, himself an anesthesiologist, particularly recommends you learn what specific anesthetic will be used (there are many, and they’re all a bit different!), and what effects (and/or after-effects) that may have.
    • Reframe—you’re not just a patient; you’re a customer/client. Many people suffer from MDeity syndrome, and view doctors as authority figures, rather than what they are: service providers.
    • Request—if something would make you feel better, ask for it. If it’s information, they will be not only obliged, but also enthusiastic, to give it. If it’s something else, they’ll oblige if they can, and the worst case scenario is something won’t be possible, but you won’t know if you don’t ask.

    Next up, help them to help you

    There are various ways you can be a useful member of your own care team:

    • Go into surgery as healthy as you can. If there’s ever a time to get a little fitter, eat a little healthier, prioritize good quality sleep more, the time approaching your surgery is the time to do this.
      • This will help to minimize complications and maximize recovery.
    • Take with you any meds you’re taking, or at least have an up-to-date list of what you’re taking. Dr. Bonney has very many times had patients tell him such things as “Well, let me see. I have two little pink ones and a little white one…” and when asked what they’re for they tell him “I have no idea, you’d need to ask my doctor”.
      • Help them to help you; have your meds with you, or at least a comprehensive list (including: medication name, dosage, frequency, any special instructions)
    • Don’t stop taking your meds unless told to do so. Many people have heard that one should stop taking meds before a surgery, and sometimes that’s true, but often it isn’t. Keep taking them, unless told otherwise.
      • If unsure, ask your surgical team in advance (not your own doctor, who will not be as familiar with what will or won’t interfere with a surgery).

    Do any preparatory organization well in advance

    Consider the following:

    • What do you need to take with you? Medications, clothes, toiletries, phone charger, entertainment, headphones, paperwork, cash for the vending machine?
    • Will the surgeons need to shave anywhere, and if so, might you prefer doing some other form of depilation (e.g. waxing etc) yourself in advance?
    • Is your list of medications ready?
    • Who will take you to the hospital and who will bring you back?
    • Who will stay with you for the first 24 hours after you’re sent home?
    • Is someone available to look after your kids/pets/plants etc?

    Be aware of how you do (and don’t) need to fast before surgery

    The American Society of Anesthesiologists gives the following fasting guidelines:

    • Non-food liquids: fast for at least 2 hours before surgery
    • Food liquids or light snacks: fast for at least 6 hours before surgery
    • Fried foods, fatty foods, meat: fast for at least 8 hours before surgery

    (see the above link for more details)

    Dr. Bonney notes that many times he’s had patients who’ve had the worst thirst, or caffeine headache, because of abstaining unnecessarily for the day of the surgery.

    Unless told otherwise by your surgical team, you can have black coffee/tea up until two hours before your surgery, and you can and should have water up until two hours before surgery.

    Hydration is good for you and you will feel the difference!

    Want to know more?

    Dr. Bonney has his own website and blog, where he offers lots of advice, including for specific conditions and specific surgeries, with advice for before/during/after your hospital stay.

    He also has a book with many more tips like those we shared today:

  • Easing Election Stress & Anxiety

    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.

    At the time of writing, the US is about to have a presidential election. Most of our readers are Americans, and in any case, what the US does tends to affect most of the world, so certainly many readers in other countries will be experiencing stress and anxiety about it too.

    We’re a health science publication, not a political outlet, so we’ll refrain from commenting on any candidates or campaign policies, and we’d also like to be clear we are not urging you to any particular action politically—our focus today is simply about mental health.

    First, CBT what can be CBT’d

    Cognitive Behavioral Therapy (CBT) is far from a panacea, but it’s often a very good starting point. And when it seems the stakes are high, it’s easy to fall into such cognitive distortions as “crystal ball” and “catastrophization”, that is to say, predicting the future and feeling the impact of that (probably undesired version of the) future, and also feeling like it will be the end of the world.

    Recognizing these processes and how they work, is the first step to managing our feelings about them.

    Learn more: The Art of Being Unflappable (Tricks For Daily Life)

    Next, DBT what can be DBT’d

    A lot of CBT hinges on the assumption that our assumptions are incorrect. For example, that our friend does not secretly despise us, that our spouse is not about to leave us, that the symptoms we are experiencing are not cancer, and in this case, that the election outcome will not go badly, and if it does, the consequences will be less severe than imagined.

    But… What if our concerns are, in fact, fully justified? Here’s where Dialectic Behavior Therapy (DBT) comes in, and with it, what therapists call “radical acceptance”.

    In other words, we accept up front the idea that maybe it’s going to be terrible and that will truly suck, and then either:

    • there’s nothing we can reasonably do about it now (so worrying just means you’ll suffer twice), or
    • there is something we can reasonably do about it now (so we can go do that thing)

    After doing the thing (if appropriate), defer processing the outcome of the election until after the election. There is no point in wasting energy to worry before then. In a broadly two-party system where things are usually close between those two largest parties, there’s something close to a 50% chance of an outcome that’s, at least, not the worst you feared.

    Learn more: CBT, DBT, & Radical Acceptance

    Lastly, empower yourself with Behavioral Activation (BA)

    Whatever the outcome of any given election, the world will keep turning, and the individual battles about any given law or policy or such will continue to go on. That’s not to say an election won’t change things—it will—but there will always still be stuff to do on a grassroots level to make the world a better place, no matter what politician has been elected.

    Being involved in doing things on a community level will not only help banish any feelings of despair (and if you got the election outcome you wanted, it’ll help you feel involved), but also, it can give you a sense of control, and can even form a part of the “ikigai” that is often talked about as one of the pillars of healthy longevity.

  • Beating Sleep Apnea

    Healthier, Natural Sleep Without Obstruction!

    Obstructive Sleep Apnea, the sleep disorder in which one periodically stops breathing (and thus wakes up) repeatedly through the night, affects about 25% of men and 10% of women:

    Prevalence of Obstructive Sleep Apnea Syndrome: A Single-Center Retrospective Study

    Why the gender split?

    There are clues that suggest it is at least partially hormonal: once women have passed menopause, the gender split becomes equal.

    Are there other risk factors?

    There are few risk other factors; some we can’t control, and some we can:

    • Being older is riskier than being younger
    • Being overweight is riskier than not being overweight
    • Smoking is (what a shock) riskier than not smoking
    • Chronic respiratory diseases increase risk, for example:
      • Asthma
      • COPD
      • Long COVID*—probably. The science is young for this one so far, so we can’t say for sure until more research has been done.
    • Some hormonal conditions increase risk, for example:

    *However, patients already undergoing Continuous Positive Airway Pressure (CPAP) treatment for obstructive sleep apnea may have an advantage when fighting a COVID infection:

    Prolonged Effects of the COVID-19 Pandemic on Sleep Medicine Services—Longitudinal Data from the Swedish Sleep Apnea Registry

    What can we do about it?

    Avoiding the above risk factors, where possible, is great!

    If you are already suffering from obstructive sleep apnea, then you probably already know about the possibility of a CPAP device; it’s a mask that one wears to sleep, and it does what its name says (i.e. it applies continuous positive airway pressure), which keeps the airway open.

    We haven’t tested these, but other people have, so here are some that the Sleep Foundation found to be worthy of note:

    Sleep Foundation | Best CPAP Machines of 2024

    What can we do about it that’s not CPAP?

    Wearing a mask to sleep is not everyone’s preferred way to do things. There are also a plethora of surgeries available, but we’ll not review those, as those are best discussed with your doctor if necessary.

    However, some lifestyle changes can help, including:

    • Lose weight, if overweight. In particular, having a collar size under 16” for women or under 17” for men, is sufficient to significantly reduce the risk of obstructive sleep apnea.
    • Stop smoking, if you smoke. This one, we hope, is self-explanatory.
    • Stop drinking alcohol, or at least reduce intake, if you drink. People who consume alcohol tend to have more frequent, and longer, incidents of obstructive sleep apnea. See also: How To Reduce Or Quit Drinking
    • Avoid sedatives and muscle relaxants, if it is safe for you to do so. Obviously, if you need them to treat some other condition you have, talk this through with your doctor. But basically, they can contribute to the “airway collapses on itself” by reducing the muscular tension that keeps your airway the shape it’s supposed to be.
    • Sleep on your side, not your back. This is just plain physics, and a matter of wear the obstruction falls.
    • Breathe through your nose, not through your mouth. Initially tricky to do while sleeping, but the more you practice it while awake, the more it becomes possible while asleep.
    • Consider a nasal decongestant before sleep, if congestion is a problem for you, as that can help too.

  • Eggcellent News Against Dementia?

    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.

    It’s that time of the week again… We hope all our readers have had a great and healthy week! Here are some selections from health news from around the world:

    Moderation remains key

    Eggs have come under the spotlight for their protective potential against dementia, largely due to their content of omega-3 fatty acids, choline, and other nutrients.

    Nevertheless, the study had some limitations (including not measuring the quantity of eggs consumed, just the frequency), and while eating eggs daily showed the lowest rates of dementia, not eating them at all did not significantly alter the risk.

    Eating more than 2 eggs per day is still not recommended, however, for reasons of increasing the risk of other health issues, such as heart disease.

    Read in full: Could eating eggs prevent dementia?

    Related: Eggs: Nutritional Powerhouse or Heart-Health Timebomb?

    More than suitable

    It’s common for a lot of things to come with the warning “not suitable for those who are pregnant or nursing”, with such frequency that it can be hard to know what one can safely do/take while pregnant or nursing.

    In the case of COVID vaccines, though, nearly 90% of babies who had to be hospitalized with COVID-19 had mothers who didn’t get the vaccine while they were pregnant.

    And as for how common that is: babies too young to be vaccinated (so, under 6 months) had the highest covid hospitalization rate of any age group except people over 75.

    Positive dieting

    Adding things into one’s diet is a lot more fun than taking things out, is generally easier to sustain, and (as a general rule of thumb; there are exceptions of course) give the greatest differences in health outcomes.

    This is perhaps most true of beans and pulses, which add many valuable vitamins, minerals, protein, and perhaps most importantly of all (single biggest factor in reducing heart disease risk), fiber.

    Clearing out disordered thinking

    Hoarding is largely driven by fear of loss, and this radical therapy tackles that at the root, by such means as rehearsing alternative outcomes of discarding through imagery rescripting, and examining the barriers to throwing things away—to break down those barriers one at a time.

    Superfluous

    Fluoridated water may not be as helpful for the teeth as it used to be prior to about 1975. Not because it became any less effective per se, but because of the modern prevalence of fluoride-containing toothpastes, mouthwashes, etc rendering it redundant in more recent decades.

    Off-label?

    With rising costs of living including rising healthcare costs, and increasing barriers to accessing in-person healthcare, it’s little wonder that many are turning to the gray market online to get their medications.

    These websites typically use legal loopholes to sell prescription drugs to the public, by employing morally flexible doctors who are content to expediently rubber-stamp prescriptions upon request, on the basis of the patient having filled out a web form and checked boxes for their symptoms (and of course also having waived all rights of complaint or legal recourse).

    However, some less scrupulous sorts are exploiting this market, to sell outright fake medications, using a setup that looks like a “legitimate” gray market website. Caveat emptor indeed.

    A rising threat

    In 2021 (we promise the paper was published only a few days ago!), the leading causes of death were:

    1. COVID-19
    2. Heart disease
    3. Stroke

    …which latter represented a rising threat, likely in part due to the increase in the aging population.

  • How To Eat To Lose Belly Fat (3 Stages)

    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.

    Belly fat is easier to gain than it is to lose, and it’s absolutely something that needs more attention in the kitchen than in the gym. Here’s one way of doing it:

    By the numbers

    First note: this video is by a man, and judging by the numbers mentioned, assumes that the viewer is also a man. An end goal of 10% body fat is a little on the low side for men, and would be dangerous for women. The magic 15% mark that he mentions as being a point where various metabolic things change, is more like 20% for women. All assuming normal hormones, of course, since it is hormones that direct this.

    Healthy body fat percentages are (assuming normal hormones) in the range of 20–25% for women and 15–20% for men.

    With that in mind…

    The idea of this approach is to lose enough weight that your body gets rid of even the most awkward bits (e.g: visceral belly fat, which will often be the last to get used) before, if desired, then maintaining at a slightly higher body fat percentage.

    • Stage 1: count calories (we don’t usually recommend this at 10almonds, but he does, so we’re reporting it here) and use your weight in pounds multiplied by 12 to give your daily calorie target. Make the majority of your diet foods that have a large volume:calorie ratio, such as fruits and vegetables, in order to feel full without overloading your metabolism. He has an interesting method of calculating a protein target; instead of the usual “1g/kg of body weight”, he says 1g per cm of height. Doing this consistently should get you to 15% body fat (so, 20%, for women).
    • Stage 2: start counting fat intake too, and aim for 20–25% of your daily calories as fat. Continue, aside from that, with what you were doing in Stage 1. Doing this consistently should get you to 12% body fat (so, about 17%, for women). Being under the usual healthy level for a while should allow your body to start getting rid of visceral fat.
    • Stage 3: track everything, levelling up your precision (no more “this little thing doesn’t count”), and planning ahead when it comes to social events etc. Doing this consistently should yet you to 10% body fat (so, about 15%, for women). This stage has a good chance of making most people miserable, so if that happens, consider the benefits of going back to the healthier 15% body fat (men) or 20% (women).
