6 Daily Habits To Keep Your Brain Young & Sharp

Without brain health, we do not have health. So here are six ways to keep it in order:
Food for thought
The six areas to focus on are as follows:
- Physical exercise: as we at 10almonds sometimes say, what’s good for the heart is good for the brain (because the brain is only as healthy as the circulation feeding it). For this reason, the recommendation here is for physical exercise that improves heart health—so, walking, running, swimming, dancing, etc.
- Healthy diet: shocking nobody, this is important too. Specifically, a diet rich in fruits, vegetables, and healthy proteins and fats is important—partly for the heart benefits that give indirect benefits to the brain, and partly because the brain is built of stuff and so we have to consume that stuff in order to rebuild it (omega-3s features strongly here, for instance). Remember to hydrate, too! The body can’t do anything without water.
- Good sleep: yes, the famous 7–9 hours sleep per night, and yes, even at your age, whatever that might be. This is important for memory consolidation, cell repair, toxin removal, and more. Sleep deprivation, on the other hand, leads to cognitive decline and brain shrinkage.
- Mental stimulation: ideally, engaging those parts of the brain you most wish to protect (e.g. language, memory, or whatever is most important to you).
- Social interaction: this one gets underestimated a lot, but it’s important to have meaningful conversations (not just polite smalltalk from a small menu of stock phrases), and that these should be two-way, i.e. involving both listening/reading and speaking/writing. Ideally, all four of those, which for most people means online and offline social interactions.
- Stress management: because chronic stress damages brain cells and accelerates cognitive decline, it’s important to manage that; practices like mindfulness meditation go a very long way and make a big difference.

What To Leave Off Your Table (To Stay Off This Surgeon’s)
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.
Why we eat too much (and how we can fix that)
This is Dr. Andrew Jenkinson. He’s a Consultant Surgeon specializing in the treatment of obesity, gallstones, hernias, heartburn and abdominal pain. He runs regular clinics in both London and Dubai. What he has to offer us today, though, is insight as to what’s on our table that puts us on his table, and how we can quite easily change that up.
So, why do we eat too much?
First things first: some metabolic calculations. No, we’re not going to require you to grab a calculator here… Your body does it for you!
Our body’s amazing homeostatic system (the system that does its best to keep us in the “Goldilocks Zone” of all our bodily systems; not too hot or too cold, not dehydrated or overhydrated, not hyperglycemic or hypoglycemic, blood pressure not too high or too low, etc, etc) keeps track of our metabolic input and output.
What this means: if we increase or decrease our caloric consumption, our body will do its best to increase or decrease our metabolism accordingly:
- If we don’t give it enough energy, it will try to conserve energy (first by slowing our activities; eventually by shutting down organs in a last-ditch attempt to save the rest of us)
- If we give it too much energy, it will try to burn it off, and what it can’t burn, it will store
In short: if we eat 10% or 20% more or less than usual, our body will try to use 10% to 20% more or less than usual, accordingly.
So… How does this get out of balance?
The problem is in how our system does that, and how we inadvertently trick it, to our detriment.
For a system to function, it needs at its most base level two things—a sensor and a switch:
- A sensor: to know what’s going on
- A switch: to change what it’s doing accordingly
Now, if we eat the way we’re evolved to—as hunter-gatherers, eating mostly fruit and vegetables, supplemented by animal products when we can get them—then our body knows exactly what it’s eating, and how to respond accordingly.
Furthermore, that kind of food takes some eating! Most fruit these days is mostly water and fiber; in those days it often had denser fiber (before agricultural science made things easier to eat), but either way, our body knows when we are eating fruit and how to handle that. Vegetables, similarly. Unprocessed animal products, again, the gut goes “we know what this is” and responds accordingly.
But modern ultra-processed foods with trans-fatty acids, processed sugar and flour?
These foods zip calories straight into our bloodstream like greased lightning. We get them so quickly so easily and in such great caloric density, that our body doesn’t have the chance to count them on the way in!
What this means is: the body has no idea what it’s just consumed or how much or what to do with it, and doesn’t adjust our metabolism accordingly.
Bottom line:
Evolutionarily speaking, your body has no idea what ultra-processed food is. If you skip it and go for whole foods, you can, within the bounds of reason, eat what you like and your body will handle it by adjusting your metabolism accordingly.
Now, advising you “avoid ultra-processed foods and eat whole foods” was probably not a revelation in and of itself.
But: sometimes knowing a little more about the “why” makes the difference when it comes to motivation.

Dioscorea Villosa: Hormones, Arthritis, & Skin
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.
On A Wild Yam Chase?
We recently came across a supplement blend that had wild yam extract as a minor ingredient. Our plucky (and usually very knowledgable) researcher had never heard of its use before, so she set about doing her thing. This is what she found…
What health claims are made?
Wild yam extract (Dioscorea villosa) is traditionally sold and used for:
- Balancing hormones
- Combating arthritis
- Anti-aging effects for the skin
Does it balance hormones?
First, as a quick catch-up, we’ll drop a previous article of ours for your convenience:
What Does “Balance Your Hormones” Even Mean?
We couldn’t find almost any studies into wild yam extract’s hormone-balancing effects, but we did find one study, and:
❝Symptom scores showed a minor effect of both placebo and active treatment on diurnal flushing number and severity and total non-flushing symptom scores, and on nocturnal sweating after placebo, but no statistical difference between placebo and active creams.
This study suggests that short-term treatment with topical wild yam extract in women suffering from menopausal symptoms is free of side-effects, but appears to have little effect on menopausal symptoms❞
…which is a very thorough, polite, sciencey way of saying “wow, this does so many different kinds of nothing”
On the one hand, this was a small study (n=23). On the other hand, it was also literally the only study we could find.
Does it combat arthritis?
Maybe! We again didn’t find much research into this but we did find two in vitro studies that suggests that diosgenin (which can be derived from wild yam extract) helps:
- Diosgenin inhibits IL-1β-induced expression of inflammatory mediators in human osteoarthritis chondrocytes
- Diosgenin, a plant steroid, induces apoptosis in human rheumatoid arthritis synoviocytes with cyclooxygenase-2 overexpression
And we also found a rodent study that found that wild yam extract specifically helped against “acetic acid-induced writhing and formalin-induced pain“, and put that down to anti-inflammatory properties:
So, none of these studies tell us much about whether it would be helpful for humans—with or without arthritis, and hopefully without “acetic acid-induced writhing and formalin-induced pain”.
However, they do suggest that it would be reasonable to test in humans next.

- How to Prevent (or Reduce) Inflammation
Does it keep skin young?
Again, research is thin on the ground, but we did find some! A study with wild-yam-derived diosgenin found that it didn’t make anything worse, and otherwise performed a similar role to vitamin A:
Read: Novel effects of diosgenin on skin aging
That was on rats with breast cancer though, so its applicability to healthy humans may be tenuous (while in contrast, simply getting vitamin A instead is a known deal).
Summary
- Does it balance hormones? It probably does little to nothing in this regard
- Does it combat arthritis? It probably has anti-inflammatory effects, but we know of no studies in humans. There are much more well-established anti-inflammatories out there.
- Does it keep the skin young? We know that it performs a role similar to vitamin A for rats with breast cancer, and didn’t make anything worse for them. That’s the extent of what we know.
Where can I get some?
In the unlikely event that the above research review has inspired you with an urge to buy wild yam extract, here is an example product for your convenience.
Some final words…
If you are surprised that we’re really not making any effort to persuade you of its merits, please know that (outside of the clearly-marked sponsor section, which helps us keep the lights on, so please do visit those) we have no interest in selling you anything. We’re genuinely just here to inform 🙂
If you are wondering why we ran this article at all if the supplement has negligible merits, it’s because science is science, knowledge is knowledge, and knowing that something has negligible merit can be good knowledge to have!
Also, running articles like this from time to time helps you to know that when we do sing the praises of something, it’s with good reason
Take care!

Seniors: Improve Blood Flow & Circulation In Your Legs
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. Doug Weiss, a physiotherapist (and thus: a doctor of physical therapy), has advice on how and why to increase blood flow and circulation in your legs, keeping yourself healthier for longer and avoiding a lot of potential unpleasantries.
The exercises
The exercises here are not complex; they are as follows, and he suggests 3 sets of 10 reps of each, daily:
- Sitting ankle pumps: sitting on a chair or the edge of a bed, lift the toes up, then heels up, squeezing the muscles.
- Sitting knee extensions: sitting as before, kick one leg up until knee is straight, then switch legs.
- Heel raises: standing this time, with a sturdy support such as a countertop, raise on toes as high as possible, then lower heels back to the ground
- Pillow squats: placing pillows on a chair, cross hands on chest, and simply stand up and sit down—similar to the “getting up off the floor without using your hands” exercise, but an easier version.
For visuals on these, and more details including the specific benefits of each, enjoy:

Water Water Everywhere, But Which Is Best To Drink?
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.
Well Well Well…
In Tuesday’s newsletter, we asked you for your (health-related) opinion on drinking water—with the understanding that this may vary from place to place. We got the above-depicted, below-described, set of responses:
- About 65% said “Filtered is best”
- About 20% said “From the mains is best”
- About 8% said “Bottled is best”
- About 3% said “Distilled is best”
- About 3% said “Some other source is best”
Of those who said “some other source is best”, one clarified that their preferred source was well water.
So what does the science say?
Fluoridated water is bad for you: True or False?
False, assuming a normal level of consumption. Rather than take up more space today though, we’ll link to what we previously wrote on this topic:
You may be wondering: but what if my level of consumption is higher than normal?
Let’s quickly look at some stats:
- The maximum permitted safety level varies from place to place, but is (for example) 2mg/l in the US, 1.5mg/l in Canada & the UK.
- The minimum recommended amount also varies from place to place, but is (for example) 0.7mg/l in Canada and the US, and 1mg/l in the UK.
It doesn’t take grabbing a calculator to realize that if you drink twice as much water as someone else, then depending on where you are, water fluoridated to the minimum may give you more than the recommended maximum.
However… Those safety margins are set so much lower than the actual toxicity levels of fluoride, that it doesn’t make a difference.
For example: your writer here takes a medication that has the side effect of causing dryness of the mouth, and consequently she drinks at least 3l of water per day in a climate that could not be described as hot (except perhaps for about 2 weeks of the year). She weighs 72kg (that’s about 158 pounds), and the toxicity of fluoride (for ill symptoms, not death) is 0.2mg/kg. So, she’d need 14.4mg of fluoride, which even if the water fluoridation here were 2mg/l (it’s not; it’s lower here, but let’s go with the highest figure to make a point), would require drinking more than 7l of water faster than the body can process it.
For more about the numbers, check out:
Acute Fluoride Poisoning from a Public Water System
Bottled water is the best: True or False?
False, if we consider “best” to be “healthiest”, which in turn we consider to be “most nutrients, with highest safety”.
Bottled water generally does have higher levels of minerals than most local mains supply water does. That’s good!
But you know what else is generally has? Microplastics and nanoplastics. That’s bad!
We don’t like to be alarmist in tone; it’s not what we’re about here, but the stats on bottled water are simply not good; see:
We Are Such Stuff As Bottles Are Made Of
You may be wondering: “but what about bottled water that comes in glass bottles?”
Indeed, water that comes in glass bottles can be expected to have lower levels of plastic than water that comes in plastic bottles, for obvious reasons.
However, we invite you to consider how likely you believe it to be that the water wasn’t stored in plastic while being processed, shipped and stored, before being portioned into its final store-ready glass bottles for end-consumer use.
Distilled water is the best: True or False?
False, generally, with caveats:
Distilled water is surely the safest water anywhere, because you know that you’ve removed any nasties.
However, it’s also devoid of nutrients, because you also removed any minerals it contained. Indeed, if you use a still, you’ll be accustomed to the build-up of these minerals (generally simplified and referenced as “limescale”, but it’s a whole collection of minerals).
Furthermore, that loss of nutrients can be more than just a “something good is missing”, because having removed certain ions, that water could now potentially strip minerals from your teeth. In practice, however, you’d probably have to swill it excessively to cause this damage.
Nevertheless, if you have the misfortune of living somewhere like Flint, Michigan, then a water still may be a fair necessity of life. In other places, it can simply be useful to have in case of emergency, of course.
Here’s an example product on Amazon if you’d like to invest in a water still for such cases.
PS: distilled water is also tasteless, and is generally considered bad, tastewise, for making tea and coffee. So we really don’t recommend distilling your water unless you have a good reason to do so.
Filtered water is the best: True or False?
True for most people in most places.
Let’s put it this way: it can’t logically be worse than whatever source of water you put into it…
Provided you change the filter regularly, of course.
Otherwise, after overusing a filter, at best it won’t be working, and at worst it’ll be adding in bacteria that have multiplied in the filter over however long you left it there.
You may be wondering: can water filters remove microplastics, and can they remove minerals?
The answer in both cases is: sometimes.
- For microplastics it depends on the filter size and the microplastic size (see our previous article for details on that).
- For minerals, it depends on the filter type. Check out:
The H2O Chronicles | 5 Water Filters That Remove Minerals
One other thing to think about: while most water filtration jugs are made of PFAS-free BPA-free plastics for obvious reasons, for greater peace of mind, you might consider investing in a glass filtration jug, like this one ← this is just one example product on Amazon; by all means shop around and find one you like

Mung Beans vs Red Lentils – 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 mung beans to red lentils, we picked the lentils.
Why?
Both are great! But the lentils win on overall nutritional density.
In terms of macros, they have approximately the same carbs and fiber, and are both low glycemic index foods. The deciding factor is that the lentils have slightly more protein—but it’s not a huge difference; both are very good sources of protein.
In the category of vitamins, mung beans have more of vitamins A, E, and K, while red lentils have more of vitamins B1, B2, B3, B5, B6, B9, C, and choline. An easy win for lentils.
When it comes to minerals, again both are great, but mung beans have more calcium and magnesium (hence the green color) while red lentils have more copper, iron, manganese, phosphorus, potassium, selenium, and zinc. Another clear win for lentils.
Polyphenols are also a worthy category to note here; both have plenty, but red lentils have more, especially flavonols, anthocyanidins, proanthocyanidins, and anthocyanins (whence the red color).
In short: enjoy both, because diversity is almost always best. But if you’re picking one, red lentils are the most nutritious of the two.

Somatic Exercises For Nervous System Regulation – by Rose Kilian
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 written before about the vagus nerve, its importance, and how to make use of it, but it’s easy to let it slip from one’s mind when it comes to exercises. This book fixes that!
The promised 35 exercises are quite a range, and are organized into sections:
- Revitalizing through breath
- Stress and tension release
- Spinal and postural health
- Mindfulness and grounding
- Movements for flexibility
- Graceful balance and focus
While it’s not necessary to do all 35 exercises, it’s recommended to do at least some from each section, to “cover one’s bases”, and enjoy the best of all worlds.
The exercises are drawn from many sources, but tai chi and yoga are certainly the most well-represented. Others, meanwhile, are straight from physiotherapy or are things one might expect to be advised at a neurology consultation.
Bottom line: if you’d like to take better care of your vagus nerve, the better for it to take care of you, this book can certainly help with that.
Click here to check out Somatic Exercises For Nervous System Regulation, and take care of yourself!
