At 10almonds we talk often of the health benefits of walking, so what’s new here?
As the subtitle suggests: a new scientific exploration!
Dr. Shane O’Mara is a professor of experimental brain research—and a keen walker. Combining his profession and his passion, he offers us a uniquely well-grounded perspective.
While the writing style is very readable, there’s a lot of science referenced here, with many studies cited. We love that!
We begin our journey by learning what we have in common with sea squirts, and what we have different from all other apes. What we can learn from other humans, from toddlers to supercentenarians.
As one might expect from a professor of experimental brain research, we learn a lot more about what walking does for our brain, than for the rest of our body. We’ve previously talked about walking and cardiovascular health, and brown adipose tissue, and benefits to the immune system, but this book remains steadfastly focused on the brain.
Which just goes to show, what a lot there is to say for the science-based benefits to our brain health, both neurologically and psychologically!
One of the things at which Dr. O’Mara excels that this reviewer hasn’t seen someone do so well before, is neatly tie together the appropriate “why” and “how” to each “what” of the brain-benefits of walking. Not just that walking boosts mood or creativity or problem-solving, say, but why and how it does so.
Often, understanding that can be the difference between being motivated to actually do it or not!
Bottom line: if there’s a book that’ll get you lacing up your walking shoes, this’ll be the one.

The Kitchen Doctor

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.

Ending Aging – by Dr. Aubrey de Grey
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 know about how to slow aging. We know about diet, exercise, sleep, intermittent fasting, and other lifestyle tweaks to make. But how much can we turn back the clock, according to science?
Dr. Aubrey de Grey’s foundational principle is simple: the body is a biological machine, and aging is fundamentally an engineering problem.
He then outlines the key parts to that problem: the princple ways in which cells (and DNA) get damaged, and what we need to do about that in each case. Car tires get damaged over time; our approach is to replace them within a certain period of time so that they don’t blow out. In the body, it’s a bit similar with cells so that we don’t get cancer, for example.
The book goes into detail regards each of the seven main ways we accumulate this damage, and highlights avenues of research looking to prevent it, and in at least some cases, the measures already available to so.
Bottom line: if you want a hard science overview of actual rejuvenation research in biogerontology, this is a book that presents that comprehensively, without assuming prior knowledge.

Gut Feelings – by Dr Will Cole
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.
More and more, science is uncovering links between our gut health and the rest of our health—including our mental health! We all know “get some fiber and consider probiotics”, but what else is there that we can do?
Quite a lot, actually. And part of it, which Dr. Cole also explores, is the fact that the gut-brain highway is a two-way street!
The book looks a lot especially at the particular relationship between shame and eating. The shame need not initially be about eating, though it can certainly end up that way too. But any kind of shame—be it relating to one’s body, work, relationship, or anything else, can not only have a direct effect on the gut, but indirect too:
Once our “eating our feelings” instinct kicks in, things can spiral from there, after all.
So, Dr. Cole walks us through tackling this from both sides—nutrition and psychology. With chapters full of tips and tricks, plus a 21-day plan (not a diet plan, a habit integration plan), this book hits shame (and inflammation, incidentally) hard and leads us into much healthier habits and cycles.
In short: if you’d like to have a better relationship with your food, improve your gut health, and/or reduce inflammation, this is definitely a book for you!

5 Things You Can Change About Your Personality (But: Should You?)
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 many personality-typing systems that, with varying degrees of validity*, aim to describe a person’s personality.
*and often pseudoscience:
- sometimes obviously so like astrology
- sometimes dressed up in clinical words like the Meyers-Briggs
- sometimes openly, per “this is not science but you may find it useful to frame things this way”, like the Enneagram
There is currently one kind of personality-typing system (with some minor variations) that is used in the actual field of clinical psychology, specifically under the umbrella of “trait theory”, and that is…
The “Big Five” personality traits
Also called the OCEAN or CANOE model, based on its 5 components:
- openness to experience: inventive/curious rather than consistent/cautious
- conscientiousness: efficient/organized rather than extravagant/careless
- extraversion: outgoing/energetic rather than solitary/reserved
- agreeableness: friendly/compassionate rather than critical/judgmental
- neuroticism: sensitive/nervous rather than resilient/confident
The latter (neuroticism) is not to be confused with neurosis, which is very different and beyond the scope of today’s article.
Note that some of these seem more positive/negative than others at a glance, but really, any of these could be a virtue or a vice depending on specifics or extremity.
For scientific reference, here’s an example paper:
The Big Five Personality Factors and Personal Values
Quick self-assessment
There are of course many lengthy questionnaires for this, but in the interests of expediency:
Take a moment to rate yourself as honestly as you can, on a scale of 1–10, for each of those components, with 10 being highest for the named trait.
For example, this writer gives herself: O7, C6, E3, A8, N2 (in other words I’d say I’m fairly open, moderately conscientious, on the reserved side, quite agreeable, and quite resilient)
Now, put your rating aside (in your phone’s notes app is fine, if you hadn’t written it down already) and forget about it for the moment, because we want you to do the next exercise from scratch.
Who would you be, at your best?
Now imagine your perfect idealized self, the best you could ever be, with no constraints.
Take a moment to rate your idealized self’s personality, on a scale of 1–10, for each of those components, with 10 being highest for the named trait.
For example, this writer picks: O9, C10, E5, A8, N1.
Maybe this, or maybe your own idealized self’s personality, will surprise you. That some traits might already be perfect for you already; others might just be nudged a little here or there; maybe there’s some big change you’d like. Chances are you didn’t go for a string of 10s or 1s (though if you did, you do you; there are no wrong answers here as this one is about your preferences).
We become who we practice being
There are some aspects of personality that can naturally change with age. For example:
- confidence/resilience will usually gradually increase with age due to life experience (politely overlook teenagers’ bravado; they are usually a bundle of nerves inside, resulting in the overcompensatory displays of confidence)
- openness to experience may decrease with age, as we can get into a rut of thinking/acting a certain way, and/or simply consciously decide that our position on something is already complete and does not need revision.
But, we can decide for ourselves how to nudge our “Big Five” traits, for example:
- We can make a point of seeking out new experiences, and considering new ideas, or develop strategies for reining ourselves in
- We can use systems to improve our organization, or go out of our way to introduce a little well-placed chaos
- We can “put ourselves out there” socially, or make the decision to decline more social invitations because we simply don’t want to
- We can make a habit of thinking kindly of others and ourselves, or we can consciously detach ourselves and look on the cynical side more
- We can build on our strengths and eliminate our weaknesses, or lean into uncomfortable emotions
Some of those may provoke a “why would anyone want to…?” response, but the truth is we are all different. An artist and a police officer may have very different goals for who they want to be as a person, for example.
Interventions to change personality can and do work:
A systematic review of personality trait change through intervention
There are many ways to go about “being the change we want to see” in ourselves, and yes there can be a degree of “fake it until you make it” if that works for you, but it doesn’t have to be so. It can also simply be a matter of setting yourself reminders about the things that are most important to you.
Writer’s example: pinned above my digital workspace I have a note from my late beloved, written just under a week before death. The final line reads, “keep being the good person that you are” (on a human level, the whole note is uplifting and soothing to me and makes me smile and remember the love we shared; or to put it in clinical terms, it promotes high agreeableness, low neuroticism).
Other examples could be a daily practice of gratitude (promotes lower neuroticism), or going out of your way to speak to your neighbors (promotes higher extraversion), signing up for a new educational course (promotes higher openness) or downloading a budgeting app (promotes higher conscientiousness).
In short: be the person you want to be, and be that person deliberately, because you can.

- How (And Why) To Train Your Pre-Frontal Cortex

Food for Life – by Dr. Tim Spector
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.
This book is, as the author puts it, “an eater’s guide to food and nutrition”. Rather than telling us what to eat or not eat, he provides an overview of what the latest science has to say about various foods, and leaves us to make our own informed decisions.
He also stands firmly by the “personalized nutrition” idea that he introduced in his previous book which we reviewed the other day, and gives advice on what tests we might like to perform.
The writing style is accessible, without shying away from reference to hard science. Dr. Spector provides lots of information about key chemicals, genes, gut bacteria, and more—as well as simply providing a very enjoyable read along the way.
Bottom line: if you’d like a much better idea of what food is (and isn’t) doing what, this book is an invaluable resource.

Olive Oil vs Coconut Oil – 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 extra virgin olive oil to cold-pressed coconut oil, we picked the olive oil.
Why?
While the cold-pressed coconut oil may offer some health benefits due to its lauric acid content, its 80–90% saturated fat content isn’t great for most people. It’s a great oil when applied topically for healthy skin and hair, though!
The extra virgin olive oil has a much more uncontroversially healthy blend of triglycerides, and (in moderation) is universally recognized as very heart-healthy.
Your local supermarket, most likely, has a good extra virgin olive oil, but if you’d like to get some online, here’s an example product on Amazon for your convenience.
