Future-Proof Your Brain

This is Kimberly Wilson. She’s a psychologist, not a doctor, and/but her speciality is neurophysiology and brain health.
Here’s what she wants us to know…
Avoid this very common killer
As you’re probably aware, the #1 killer in the US is heart disease, followed by COVID, which effectively pushed everything down a place. Thereafter, we see cancer, followed by accidental injuries, stroke, and dementia (including Alzheimer’s).
Over in the UK, where Wilson is from, dementia (including Alzheimer’s disease) is the #1 killer, followed by heart disease and then respiratory diseases (including COVID), and then stroke, then cancer.
As ever, what’s good for the heart is good for the brain, so many of the same interventions will help avoid both. With regard to some of the other differences in order, the reasons are mostly due to differences in the two countries’ healthcare systems and firearms laws.
It’s worth noting, though, that the leading cause of death in young people (aged 15–19) is suicide in the UK; in the US it’s nominally accidental injuries first (e.g. accidental shootings) with intentional suicide in the second spot.
In other words… Young or old, mental health is a serious health category that kills literally the most people in the UK, and also makes the top spots in the US.
Avoid the early killer
Given the demographics of most of our readership, chances are you’ve already lived past your teens and twenties. That’s not to say that suicide is no longer a risk, though, and it’s also worth noting that while mental health issues are invisible, they’re still physical illnesses (the brain is also an organ, after all!), so this isn’t something where you can simply “decide not to” and that’s you set, safe for life. So, please do continue to take good care in that regard.
We wrote about this previously, here:
How To Stay Alive (When You Really Don’t Want To)
Avoid the later killer
Wilson talks about how a recent survey found that…
- while nearly half of adults say dementia is the disease they fear most,
- only a third of those thought you could do anything to avoid it, and
- just 1% could name the 7 known risk factors.
Quick test: can you name the 7 known risk factors?
Please take a moment to actually try (this kind of mental stimulation is good in any case), and count them out on your fingers (or write them down), and then…
When you’re ready: click here to see the answer!
How many did you get? If you got them all, well done. If not, then well, now you know, so that’s good.
So, with those 7 things in mind, the first obvious advice is to take care of those things.
Taking an evidence-based medicine approach, Wilson recommends some specific interventions that will each improve one or more of those things, directly or indirectly:
Eating right
Wilson is a big fan of “nutritional psychiatry” and feeding one’s brain properly. We wrote about this, here:
The 6 Pillars Of Nutritional Psychiatry
As well as agreeing with the obvious “eat plenty of fiber, different-colored plants, and plenty of greens and beans”, Wilson specifically also champions getting enough of vitamins B9, B12, and D, as well as getting a healthy dose of omega-3 fatty acids.
She also recommends intermittent fasting, if that’s a reasonable option for you—but advocates for not worrying about it, if it’s not easy for you. For example, if you are diabetic, or have (or have a history with) some kind of eating disorder(s), then it’s probably not usefully practicable. But for most people, it can reduce systemic inflammation, which means also reducing neuroinflammation.
Managing stress right
Here she advocates for three main things:
- Mindful meditation (see: Evidence-Based, No-Frills Mindfulness)
- Psychological resilience (see: Building Psychological Resilience)
- Mindful social media use (see: Making Social Media Work For Your Mental Health)
Managing money right
Not often we talk about this in a health science publication as opposed to a financial planning publication, but the fact is that a lot of mental distress, which goes on to have a huge impact on the brain, is rooted in financial stresses.
And, of course, it’s good to be able to draw on financial resources to directly fund one’s good health, but that is the secondary consideration here—the financial stress is the biggest issue, and you can’t CBT your way out of debt, for example.
Therapists often face this, and what has been referred to informally by professionals in the field as “Shit Life Syndrome”—and there’s only so much that therapy can do about that.
We’re not a financial publication, but one recommendation we’ll drop is that if you don’t currently have budgeting software that you use, this writer personally uses and swears by YNAB (You Need A Budget), so maybe check that out if you don’t already have everything covered in that regard. It’s not free, but there is a 34-day free trial.
Therapy can be very worthwhile nonetheless
Wilson notes that therapy is like non-invasive brain surgery (because of neuroplasticity, it’s literally changing physical things in your brain).
It’s not a magic bullet and it’s not the right choice for everyone, but it’s worth considering, and even self-therapy can yield benefits for many:

Sleeping right
Sleep is not only critical for health in general and brain health in particular, it’s also most of when our glymphatic system does clean-up in the brain (essential for avoiding Alzheimer’s & Parkinson’s, amongst other diseases):

A Planet of Viruses – by Carl Zimmer
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 reviewed numerous books on the immune system before, and this one’s mostly not about that.
Instead, this one focuses on the viruses themselves, and the part they play in our world, for good and for ill. Popular awareness tends to focus on the ill, of course.
But, there’s a lot that viruses do for us too, including:
- Weak/harmless viruses that keep our immune systems on their toes and ready
- Bacteriophage viruses that kill and consume pathogens that, left unchecked, would do the same to us
- Endogenous retroviruses that have become symbiotic with the human organism, without which our species would quickly go extinct
He also talks about biological warfare, and how we cannot bury our heads in the sand by avoiding research on those grounds, because someone will always do it anyway, so (as the motto of the immune system itself might say), best to be prepared.
The author is a science journalist, by the way, and has no PhD, but does have a flock of Fellowships and assorted scientific awards and honors, so he appears to be doing good work so far as the scientific community is concerned.
Bottom line: if you’d like to know more about viruses than “they’re very small and can cause harm”, then this book will open a whole new world.

Black Coffee vs Orange Juice – 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 black coffee to orange juice, we picked the coffee.
Why?
While this one isn’t a very like-for-like choice, it’s a choice often made, so it bears examining.
In favor of the orange juice, it has vitamins A and C and the mineral potassium, while the coffee contains no vitamins or minerals beyond trace amounts.
However, to offset that: drinking juice is one of the worst ways to consume sugar; the fruit has not only been stripped of its fiber, but also is in its most readily absorbable state (liquid), meaning that this is going to cause a blood sugar spike, which if done often can lead to insulin resistance, type 2 diabetes, non-alcoholic fatty liver disease, and more. Now, the occasional glass of orange juice (and resultant blood sugar spike) isn’t going to cause disease by itself, but everything we consume tips the scales of our health towards wellness or illness (or sometimes both, in different ways), and in this case, juice has a rather major downside that ought not be ignored.
In favor of the coffee, it has a lot of beneficial phytochemicals (mostly antioxidant polyphenols of various kinds), with no drawbacks worth mentioning unless you have a pre-existing condition of some kind.
Coffee can of course be caffeinated or decaffeinated, and we didn’t specify which here. Caffeine has some pros and cons that at worst, balance each other out, and whether or not it’s caffeinated, there’s nothing in coffee to offset the beneficial qualities of the antioxidants we mentioned before.
Obviously, in either case we are assuming consuming in moderation.
In short:
- orange juice has negatives that at least equal, if not outweigh, its positives
- coffee‘s benefits outweigh any drawbacks for most people

Heart Healthy Diet Plan – by Stephen William
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 covered heart-healthy cooking books before, but variety is good, and boredom is an enemy of health, so let’s shake it up with a fresh stack of recipes!
After a brief overview of the relevant science (which if you’re a regular 10almonds reader, probably won’t be new to you), the author takes the reader on a 28-day journey. Yes, we know the subtitle says 30 days, but unless they carefully hid the other two days somewhere we didn’t find, there are “only” 28 inside. Perhaps the publisher heard it was a month and took creative license. Or maybe there’s a different edition. Either way…
Rather than merely giving a diet plan (though yes, he also does that), he gives a wide range of “spotlight ingredients”, such that many of the recipes, while great in and of themselves, can also be jumping-off points for those of us who like to take recipes and immediately do our own things to them.
Each day gets a breakfast, lunch, dinner, and he also covers drinks, desserts, and such like.
Notwithstanding the cover art being a lot of plants, the recipes are not entirely plant-based; there are a selection of fish dishes (and other seafood, e.g. shrimp) and also some dairy products (e.g. Greek yoghurt). The recipes are certainly very “plant-forward” though and many are just plants. If you’re a strict vegan though, this probably isn’t the book for you.
Bottom line: if you’d like to cook heart-healthy but are often stuck wondering “aaah, what to cook again today?”, then this is the book to get you out of any culinary creative block!

Air Purifiers & Sleep
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 Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I’ve read that air pollution has a negative effect on sleep quality and duration. Since I live next to a busy road, I was wondering whether I should invest in an air purifier. What are 10Almonds’s views?❞
Going straight to the science, there are two questions here:
- Does air pollution negatively affect sleep quality and duration?
- Does the use of an air purify actually improve the air quality in the way(s) necessary to make a difference?
We thought we’d have to tackle these questions separately, but we did find one study that addressed your question directly. It was a small study (n=30 if you believe the abstract; n=29 if you read the paper itself—one person dropped out); the results were modest but clear:
❝The purifier filter was associated with increased total sleep time for an average of 12 min per night, and increased total time in bed for an average of 19 min per night relative to the placebo.
There were several sleep and mood outcomes for which no changes were observed, and time awake after sleep onset was higher for the purifier filter. Air quality was better during the high-efficiency particulate air filter condition.
These findings offer positive indications that environmental interventions that improve air quality can have benefits for sleep outcomes in healthy populations who are not exhibiting clinical sleep disturbances.❞
In the above-linked paper’s introduction, it does establish the deleterious effect of air pollution on a wide variety of health metrics, including sleep, this latter evidenced per Caddick et al. (2018): A review of the environmental parameters necessary for an optimal sleep environment
Now, you may be wondering: is an extra 12 minutes per night worth it?
That’s your choice to make, but we would argue that it is. We can make many choices in our lives that affect our health slightly for the better or the worse. If we make a stack of choices in a particular direction, the effects will also stack, if not outright compound.
So in the case of sleep, it might be (arbitrary numbers for the sake of illustration):
- Get good exercise earlier in the day (+3%)
- Get good food earlier in the day (+2.5%)
- Practice mindfulness/meditation before bed (+2.5%)
- Have a nice dark room (+5%)
- Have fresh bedding (+2.5%)
- Have an air purifier running (+3%)
Now, those numbers are, as we said, arbitrary*, but remember that percentages don’t add up; they compound. So that “+3%” starts being a lot more meaningful than if it were just by itself.
*Confession: the figure of 3% for the air purifier wasn’t entirely arbitrary; it was based on 100(12/405) = 80/27 ≈ 3, wherein the 405 figure was an approximation of the average total time (in minutes) spent sleeping with placebo, based on a peep at their results graph. There are several ways the average could be reasonably calculated, but 6h45 (i.e., 405 minutes) was an approximate average of those reasonable approximate averages.
So, 12 minutes is a 3% improvement on that.
Don’t have an air purifier and want one?
We don’t sell them, but here’s an example on Amazon, for your convenience

Kidney Beans vs Fava Beans – 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 kidney beans to fava beans, we picked the kidney beans.
Why?
It’s a simple and straightforward one today!
The macronutrient profiles are mostly comparable, but kidney beans do have a little more protein and a little more fiber.
In the category of vitamins, kidney beans have more of vitamins B1, B5, B6, B9, C, E, & K, while fava beans boast only more of vitamins B2 and B3. They are both equally good sources of choline, but the general weight of vitamins is very much in kidney beans’ favor, with a 7:2 lead, most of which have generous margins.
When it comes to minerals, kidney beans have more iron, phosphorus, and potassium, while fava beans have more copper and selenium. They’re both equally good sources of other minerals they both contain. Still, a 3:2 victory for kidney beans on the mineral front.
Adding up the moderate victory on macros, the strong victory on vitamins, and the slight victory on minerals, all in all makes for a clear win for kidney beans.
Still, enjoy both! Diversity is healthy.

The Kitchen Doctor
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. Rupy Aujla: The Kitchen Doctor
This is Dr. Rupy Aujla, and he’s a medical doctor. He didn’t set out to become a “health influencer”.
But then, a significant heart condition changed his life. Having a stronger motivation to learn more about nutritional medicine, he did a deep dive into the scientific literature, because that’s what you do when your life is on the line, especially if you’re a doctor!
Using what he learned, he was able to reverse his condition using a food and lifestyle approach. Now, he devotes himself to sharing what he learned—and what he continues to learn as he goes along.
One important thing he learned because of what happened to him, was that he hadn’t been paying enough attention to what his body was trying to tell him.
He wants us to know about interoception—which isn’t a Chris Nolan movie. Rather, interoception is the sense of what is going on inside one’s own body.
The counterpart of this is exteroception: our ability to perceive the outside world by means of our various senses.
Interoception is still using the senses, but is sensing internal body sensations. Effectively, the brain interprets and integrates what happens in our organs.
When interoception goes wrong, researchers found, it can lead to a greater likelihood of mental health problems. Having an anxiety disorder, depression, mood disorder, or an eating disorder often comes with difficulties in sensing what is going on inside the body.
Improving our awareness of body cues
Those same researchers suggested therapies and strategies aimed at improving awareness of mind-body connections. For example, mindfulness-based stress reduction, yoga, meditation and movement-based treatments. They could improve awareness of body cues by attending to sensations of breathing, cognitions and other body states.
But where Dr. Aujla puts his focus is “the heart of the home”, the kitchen.
The pleasure of food
❝Eating is not simply ingesting a mixture of nutrients. Otherwise, we would all be eating astronaut food. But food is not only a tool for health. It’s also an important pleasure in life, allowing us to connect to others, the present moment and nature.❞
Dr. Rupy Aujla
Dr. Aujla wants to help shift any idea of a separation between health and pleasure, because he believes in food as a positive route to well-being, joy and health. For him, it starts with self-awareness and acceptance of the sensory pleasures of eating and nourishing our bodies, instead of focusing externally on avoiding perceived temptations.
Most importantly:
We can use the pleasure of food as an ally to healthy eating.
Instead of spending our time and energy fighting the urge to eat unhealthy things that may present a “quick fix” to some cravings but aren’t what our body actually wants, needs, Dr. Aujla advises us to pay just a little more attention, to make sure the body’s real needs are met.
His top tips for such are:
- Create an enjoyable relaxing eating environment
To help cultivate positive emotions around food and signal to the nervous system a shift to food-processing time. Try setting the table with nothing else on it beyond what’s relevant to the dinner, putting away distractions, using your favorite plates, tablecloth, etc.
- Take 3 deep abdominal breaths before eating
To help you relax and ground yourself in the present moment, which in turn is to prepare your digestive system to receive and digest food.
- Pay attention to the way you sit
Take some time to sit comfortably with your feet grounded on the floor, not slouching, to give your stomach space to digest the food.
- Appreciate what it took to bring this food to your plate
Who was involved in the growing process and production, the weather and soil it took to grow the food, and where in the world it came from.
- Enjoy the sensations
When you’re cooking, serving, and eating your food, be attentive to color, texture, aroma and even sound. Taste the individual ingredients and seasonings along the way, when safe and convenient to do so.
- Journal
If you like journaling, you can try adding a mindful eating section to that. Ask questions such as: “how did I feel before, during, and after the meal?”
In closing…
Remember that this is a process, not only on an individual level but as a society too.
Oftentimes it’s hard to eat healthily… We can be given to wonder even “what is healthy, after all?”, and we can be limited by what is available, what is affordable, and what we have time to prepare.
But if we make a conscious commitment to make the best choices we reasonably can as we go along, then small changes can soon add up.
