Your Bones Were Made For Moving Too!
We know that to look after bone health, resistance training is generally what’s indicated. Indeed, we mentioned it yesterday, and we’ve talked about it before:
Resistance Is Useful! (Especially As We Get Older)
We also know that if you have osteoporosis already, some exercises are a better or worse idea than others:
Osteoporosis & Exercises: Which To Do (And Which To Avoid)
However! New research suggests that also getting in your recommended 150 minutes per week of moderate exercise slows bone density loss.
The study by Dr. Tiina Savikangas et al. looked at 299 people in their 70s (just over half being women) and found that, over the course of a year, bone mineral density loss was inversely correlated with moderate exercise as recorded by an accelerometer (as found in most fitness-tracking wearables and smartphones).
In other words: those who got more minutes of exercise, kept more bone mineral density.
As well as monitoring bone mineral density, the study also looked at cross-sectional area, but that remained stable throughout.
As for how much is needed:
❝Even short bursts of activity can be significant for the skeleton, so we also looked at movement in terms of the number and intensity of individual impacts. For example, walking and running cause impacts of different intensities.
We found that impacts that were comparable to at least brisk walking were associated with better preservation of bone mineral density.❞

On which note, we’ve a small bone to pick…
As a small correction, the pop-science source says that the subjects’ ages ranged from 70 to 85 years; the paper, meanwhile, clearly shows that the age-range was 74.4±3.9 years (shown in the “Results” table), rounded to 74.4 ± 4 years, in the abstract. So, certainly no participant was older than 78 years and four months.
Why this matters: the age range itself may be critical or it might not, but what is important is that this highlights how we shouldn’t just believe figures cited in pop-science articles, and it’s always good to click through to the source!
This paper is a particularly fascinating read if you have time, because—unlike a lot of studies—they really took great care to note what exactly can and cannot be inferred from the data, and how and why.
Especially noteworthy was the diligence with which they either controlled for, or recognized that they could not control for, far more variables than most studies even bother to mention.
This kind of transparency is critical for good science, and we’d love to see more of it!
Want to apply this to your life?
Tracking minutes-of-movement is one of the things that fitness trackers are best at, so connect your favourite app (one of these days we’ll do a fitness tracker comparison article) and get moving!
And as for the other things that fitness trackers do? As it turns out, they do have their strengths and weaknesses, which are good to bear in mind:

How (And Why) To Train Your Pre-Frontal Cortex
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.
Dr. Chapman’s Keys For Mental Focus
This is Dr. Sandra Chapman; she’s a cognitive neuroscientist, on a mission to, in her words, further our understanding of:
- what makes the brain stronger, faster and last longer
- what enhances human cognitive capacity, and
- what enhances the underlying brain systems across the lifespan.
To this end, she’s also the founder and Chief Director of the Center For Brain Health, where she has worked on her mission for the past 25 years (clocking up hundreds of peer-reviewed publications to her name), as well as being a professor of Behavioral and Brain Sciences at UT Dallas.
What does she want us to know?
Get your brain into gear
When it comes to your brainpower, it is “use it or lose it”, but it is also perfectly possible to use it and lose it.
Why?
Very often, what we are using our brains for is high-strain, low-yield stuff, such as multitasking, overthinking, or overthinking while multitasking. And to make it worse, we often do it without sufficient rest.
This is the equivalent of owning a Ferrari but trying to drive it in second and third gear at once by switching between the two as rapidly as possible. And doing that for 18 hours each day.
Suffice it to say, you’ll be going nowhere quickly.
An alternative “use” of brainpower is low-strain, low-yield stuff, such as having to pay close attention to a boring conversation. It’s enough to stop your mind from doing anything else, but not enough to actually stimulate you.
This is the equivalent of owning a Ferrari but keeping it idling. The wear and tear is minimal this time, but you’re not actually going anywhere either.
Better, of course, are the other two quadrants:
- low-strain, high-yield: consistently using our brain in relatively non-taxing ways that encourage its development
- high-strain, high-yield: here the Ferrari metaphor definitely fails, because unlike cars, our bodies (including our brains) are machines that benefit from judicious regular progressive overloading (but just by a bit, and with adequate recovery time between overloads).
See also: 12 Weeks To Measurably Boost Your Brain
How to do the “low-strain, low-yield” part
When it comes to “what’s the most important part of the brain to help in the face of cognitive decline?” the usual answer is either to focus on memory (hippocampi) or language (various parts, but for example Wernicke’s area and Broca’s area), since people most fear losing memory, and language is very important both socially and practically.
Those are indeed critical, and we at 10almonds stand by them, but Dr. Chapman (herself having originally trained as speech and language pathologist!) makes a strong case for adding a third brain part to the list.
Specifically, she advocates for strengthening the pre-frontal cortex, which is responsible for inhibition, task-switching, working memory, and cognitive flexibility. If that seems like a lot, do remember it’s a whole cortex and not one of the assorted important-but-small brain bits we mentioned above.
How? She has developed training programs for this, based on what she calls Strategic Memory Advanced Reasoning Tactics (SMART), to support support attention, planning, judgment and emotional management.
You can read more about those programs here:
Center For Brain Health | Our Programs
Participation in those is mostly not free, however, if you join their…
Center For Brain Health | BrainHealth Project
…then they will periodically invite you to join pilot programs, research programs, and the like, which will either be free or they-pay-you affairs—because this is how science is done, and you can read about yourself (anonymized, of course) later in peer-reviewed papers of the kind we often cite here.
If you’re not interested in any of that though, we will say that according to Dr. Chapman, the keys are:
Inhibition: be conscious of this function of your brain, and develop it. This is the function of your brain that stops you from making mistakes—or put differently: stops you from saying/doing something stupid.
Switching: do this consciously; per “I am now doing this task, now I am switching to this other task”, rather than doing the gear-grinding thing we discussed earlier
Working memory: this is effectively your brain’s RAM. Unlike the RAM of a computer (can be enhanced by adding another chip or replacing with a bigger chip), our brain’s RAM can be increased by frequent use, and especially by judicious use of progressive overloading (with rests between!) which we’ll discuss in the high-strain, high-yield section.
Flexibility: this is about creative problem-solving, openness to new ideas, and curiosity
See also: Curiosity Kills The Neurodegeneration
How to do the “high-strain, high-yield” part
Delighting this chess-playing writer, Dr. Chapman recommends chess. Although, similar games such as go (a Chinese game that looks simpler than chess but actually requires more calculation) work equally well too.
Why?
Games like chess and go cause structural changes that are particularly helpful, in terms of engaging in such foundational tasks as learning, abstract reasoning, problem-solving and self-control:
Chess Practice as a Protective Factor in Dementia
Basically, it checks (so to speak) a lot of boxes, especially for the pre-frontal cortex. Some notes:
- Focusing on the game is required for brain improvement; simply pushing wood casually will not do it. Ideally, calculating several moves ahead will allow for strong working memory use (because to calculate several moves ahead, one will have to hold increasingly many possible positions in the mind while doing so).
- The speed of play must be sufficiently slow as to allow not only for thinking, but also for what in chess is called “blunder-checking”, in other words, having decided on one’s move, pausing to consider whether it is a mistake, and actively trying to find evidence that it is. This is the crucial “inhibition habit”, and when one does it reflexively, one will make fewer mistakes. Tying this to dementia, see for example how one of the common symptoms of dementia is falling for scams that one wouldn’t have previously. How did cognitive decline make someone naïve? It didn’t, per se; it just took away their ability to, having decided what to do, pause to consider whether it was a mistake, and actively trying to find evidence that it is.
- That “conscious switching” that we talked about, rather than multitasking? In chess, there is a difference between strategy and tactics. Don’t worry about what that difference is for now (learn it if you want to take up chess), but know that strong players will only strategize while it is their opponent’s turn, and only calculate (tactics) while it is their own turn. It’s very tempting to flit constantly between one and the other, but chess requires players to have the mental discipline be able to focus on one task or the other and stick with that task until it’s the appointed time to switch.
If you feel like taking up chess, this site (and related app, if you want it) is free (it’s been funded by voluntary donations for a long time now) and good and even comes with free tuition and training tools: LiChess.org
Here’s another site that this writer (hi, it’s me) personally uses—it has great features too, but many are paywalled (I’m mostly there just because I’ve been there nearly since its inception, so I’m baked into the community now): Chess.com

Tips For Avoiding/Managing Rheumatoid Arthritis
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.
Avoiding/Managing Rheumatoid Arthritis
Arthritis is the umbrella term for a cluster of joint diseases involving inflammation of the joints, hence “arthr-” (joint) “-itis” (suffix used to denote inflammation). These are mostly, but not all, autoimmune diseases, in which the body’s immune system mistakenly attacks our own joints.
Inflammatory vs Non-Inflammatory Arthritis
Arthritis is broadly divided into inflammatory arthritis and non-inflammatory arthritis.
You may be wondering: how does one get non-inflammatory inflammation of the joints?
The answer is, in “non-inflammatory” arthritis, such as osteoarthritis, the damage comes first (by general wear-and-tear) and inflammation generally follows as part of the symptoms, rather than the cause. So the name can be a little confusing. In the case of osteo- and other “non-inflammatory” forms of arthritis, you definitely still want to keep your inflammation at bay as best you can, but it’s not as absolutely critical a deal as it is for “inflammatory” forms of arthritis.
We’ll tackle the beast that is osteoarthritis another day, however.
Today we’re going to focus on…
Rheumatoid Arthritis
This is the most common of the autoimmune forms of arthritis. Some quick facts:
- It affects a little under 1% of the global population, but the older we get, the more likely it becomes
- Early onset of rheumatoid arthritis is most likely to show up around the age of 50 (but it can show up at any age)
- However, incidence (not onset) of rheumatoid arthritis peaks in the 70s age bracket
- It is 2–4 times more common in women than in men
- Approximately one third of people stop work within two years of its onset, and this increases thereafter.
Well, that sounds gloomy.
Indeed it’s not fun. There’s a lot of stiffness and aching of joints (often with swelling too), loss of joint function can be common, and then there are knock-on effects like fatigue, weakness, and loss of appetite.
Beyond that it’s an autoimmune disorder, its cause is not known, and there is no known cure.
Is there any good news?
If you don’t have rheumatoid arthritis at the present time, you can reduce your risk factors in several ways:
- Having an anti-inflammatory diet. Get plenty of fiber, greens, and berries. Fatty fish is great too, as are oily nuts. On the other side of things, high consumption of salt, sugar, alcohol, and red meat are associated with a greater risk of developing rheumatoid arthritis.
- Not smoking. Smoking is bad for pretty much everything, including your chances of developing rheumatoid arthritis.
- Not being obese. This one may be more a matter of correlation than causation, because of the dietary factors (if one eats an anti-inflammatory diet, obesity is less likely), but the association is there.
There are other risk factors that are harder to control, such as genetics, age, sex, and having a mother who smoked.
See: Genetic and environmental risk factors for rheumatoid arthritis
What if I already have rheumatoid arthritis?
If you already have rheumatoid arthritis, it becomes a matter of symptom management.
First, reduce inflammation any (reasonable) way you can. We did a main feature on this before, so we’ll just drop that again here:
Next, consider the available medications. Your doctor may or may not have discussed all of the options with you, so be aware that there are more things available than just pain relief. To talk about them all would require a whole main feature, so instead, here’s a really well-compiled list, along with explanations about each of them, up to date as of this year:
Rheumatoid Arthritis Medication List (And What They Do, And How)
Finally, consider other lifestyle adjustments to manage your symptoms. These include:
- Exercise—gently, though! You do not want to provoke a flare-up, but you do want to maintain your mobility as best you can. There’s a use-it-or-lose-it factor here. Swimming and yoga are great options, as is tai chi. You may want to avoid exercises that involve repetitive impacts to your joints, like running.
- Rest—while keeping mobility going. Get good sleep at night (this is important), but don’t make your bed your new home, or your mobility will quickly deteriorate.
- Hot & cold—both can help, and alternating them can reduce inflammation and stiffness by improving your body’s ability to respond appropriately to these stimuli rather than getting stuck in an inappropriate-response state of inflammation.
- Mobility aids—if it helps, it helps. Maybe you only need something during a flare-up, but when that’s the case, you want to be as gentle on your body as possible while keeping moving, so if crutches, handrails etc help, then by all means get them and use them.
- Go easy on the use of braces, splints, etc—these can offer short-term relief, but at a long term cost of loss of mobility. Only you can decide where to draw the line when it comes to that trade-off.

Treat Your Own Knee – 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.
First, a note about the author: he’s a physiotherapist and not a doctor, but with 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.
The book covers recognizing the difference between arthritis, degeneration, or normal wear and tear, before narrowing down what your actual problem is and what can be done about it.
While there are many possible causes of knee pain (and by causes, we mean the first-level cause, such as “bad posture” or “old sports injury” or “inflammatory diet” or “repetitive strain” etc, not second-level causes that are also symptoms, like inflammation), McKenzie’s approach involves customizing his system to your body’s specific problems and needs. That’s what most of the book is about.
The style is direct and to-the-point; there’s no sensationalization here nor a feel of being sold anything. There’s lots of science scattered throughout, but all with the intent of enabling the reader to understand what’s going on with the problems, processes, and solutions, and why/how the things that work, work. Where there are exercises offered they are clearly-described and well-illustrated.
Bottom line: this is not a fancy book but it is an effective one. If you have knee pain, this is a very worthwhile one to read.
Click here to check out Treat Your Own Knee, and treat your own knee!
PS: if you have musculoskeletal problems elsewhere in your body, you might want to check out the rest of his body parts series (back, hip, neck, wrist, ankle, etc) for the one that’s tailored to your specific problem.

When can my baby drink cow’s milk? It’s sooner than you think
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.
Parents are often faced with well-meaning opinions and conflicting advice about what to feed their babies.
The latest guidance from the World Health Organization (WHO) recommends formula-fed babies can switch to cow’s milk from six months. Australian advice says parents should wait until 12 months. No wonder some parents, and the health professionals who advise them, are confused.
So what do parents need to know about the latest advice? And when is cow’s milk an option?
What’s the updated advice?
Last year, the WHO updated its global feeding guideline for children under two years old. This included recommending babies who are partially or totally formula fed can have whole animal milks (for example, full-fat cow’s milk) from six months.
This recommendation was made after a systematic review of research by WHO comparing the growth, health and development of babies fed infant formula from six months of age with those fed pasteurised or boiled animal milks.
The review found no evidence the growth and development of babies who were fed infant formula was any better than that of babies fed whole, fresh animal milks.
The review did find an increase in iron deficiency anaemia in babies fed fresh animal milk. However, WHO noted this could be prevented by giving babies iron-rich solid foods daily from six months.
On the strength of the available evidence, the WHO recommended babies fed infant formula, alone or in addition to breastmilk, can be fed animal milk or infant formula from six months of age.
The WHO said that animal milks fed to infants could include pasteurised full-fat fresh milk, reconstituted evaporated milk, fermented milk or yoghurt. But this should not include flavoured or sweetened milk, condensed milk or skim milk.
If you’re choosing cow’s milk for your baby, make sure it’s whole milk rather than skim milk. Mr Adi/Shutterstock Why is this controversial?
Australian government guidelines recommend “cow’s milk should not be given as the main drink to infants under 12 months”. This seems to conflict with the updated WHO advice. However, WHO’s advice is targeted at governments and health authorities rather than directly at parents.
The Australian dietary guidelines are under review and the latest WHO advice is expected to inform that process.
OK, so how about iron?
Iron is an essential nutrient for everyone but it is particularly important for babies as it is vital for growth and brain development. Babies’ bodies usually store enough iron during the final few weeks of pregnancy to last until they are at least six months of age. However, if babies are born early (prematurely), if their umbilical cords are clamped too quickly or their mothers are anaemic during pregnancy, their iron stores may be reduced.
Cow’s milk is not a good source of iron. Most infant formula is made from cow’s milk and so has iron added. Breastmilk is also low in iron but much more of the iron in breastmilk is taken up by babies’ bodies than iron in cow’s milk.
Babies should not rely on milk (including infant formula) to supply iron after six months. So the latest WHO advice emphasises the importance of giving babies iron-rich solid foods from this age. These foods include:
- meat
- eggs
- vegetables, including beans and green leafy vegetables
- pulses, including lentils
- ground seeds and nuts (such as peanut or other nut butters, but with no added salt or sugar).
You may have heard that giving babies whole cow’s milk can cause allergies. In fact, whole cow’s milk is no more likely to cause allergies than infant formula based on cow’s milk.
If you’re introducing cow’s milk at six months, offer iron-rich foods too, such as meat or lentils. pamuk/Shutterstock What are my options?
The latest WHO recommendation that formula-fed babies can switch to cow’s milk from six months could save you money. Infant formula can cost more than five times more than fresh milk (A$2.25-$8.30 a litre versus $1.50 a litre).
For families who continue to use infant formula, it may be reassuring to know that if infant formula becomes hard to get due to a natural disaster or some other supply chain disruption fresh cow’s milk is fine to use from six months.
It is also important to know what has not changed in the latest feeding advice. WHO still recommends infants have only breastmilk for their first six months and then continue breastfeeding for up to two years or more. It is also still the case that infants under six months who are not breastfed or who need extra milk should be fed infant formula. Toddler formula for children over 12 months is not recommended.
All infant formula available in Australia must meet the same standard for nutritional composition and food safety. So, the cheapest infant formula is just as good as the most expensive.
What’s the take-home message?
The bottom line is your baby can safely switch from infant formula to fresh, full-fat cow’s milk from six months as part of a healthy diet with iron-rich foods. Likewise, cow’s milk can also be used to supplement or replace breastfeeding from six months, again alongside iron-rich foods.
If you have questions about introducing solids your GP, child health nurse or dietitian can help. If you need support with breastfeeding or starting solids you can call the National Breastfeeding Helpline (1800 686 268) or a lactation consultant.

Pistachios vs Walnuts – 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 pistachios to walnuts, we picked the pistachios.
Why?
Pistachios have more protein and fiber, while walnuts have more fat (though the fats are famously healthy, the same is true of the fats in pistachios).
In the category of vitamins, pistachios have several times more* of vitamins A, B1, B6, C, and E, while walnuts boast only a little more of vitamin B9. They are approximately equal on other vitamins they both contain.
*actually 25x more vitamin A, but the others are 2x, 3x, 4x more.
When it comes to minerals, things are more even; pistachios have more iron, phosphorus, potassium, and selenium, while walnuts have more copper, magnesium, manganese, and zinc. So this category’s a tie.
So given two clear wins for pistachios, and one tie, it’s evident that pistachios win the day.
However! Do enjoy both of these nuts; we often mention that diversity is good in general, and in this case, it’s especially true because of the different mineral profiles, and also because in terms of the healthy fats that they offer, pistachios offer more monounsaturated fats and walnuts offer more polyunsaturated fats; both are healthy, just different.
They’re about equal on saturated fat, in case you were wondering, as it makes up about 6% of the total fats in both cases.
