The Neuroscience of You – by Dr. Chantel Prat

The insides of people are rarely so standardized as one finds in a medical textbook, and that’s just as true of the brain as it is of any other organ—and often more so.
Our brains all look quite different from each other’s. Of course there are similarities; a wobbly mass of white and grey matter with tiny blood vessels running through. The constituent parts are (usually!) all present and correct. But… what is “correct”?
Dr. Chantel Prat takes us on a tour of the anatomical features that we may have grown or shrunken over the course of our life, according to how we’ve used them, or not. She also looks at what’s going on when it comes to the smaller scale—from the neuronal to the neurochemical.
We learn the truth (and myth) when it comes to left- and right-brainedness, and we learn how whether we saw that dress as black and blue or white and gold, depends on our circadian rhythm (and thus whether we have wired ourselves for perceiving colors more or less often under daylight or artificial light). And lots more.
The style throughout is very accessible, for a book that goes beyond most “how the brain works” books.
Bottom line: if you’re interested in the workings of your brain (as opposed to: a standardized Platonic ideal of what a brain might be), then this book will set you on the right track.

Just Be Well – by Dr. Thomas Sult
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.
Firstly, what this is not: a “think yourself well” book. It’s not about just deciding to be well.
Rather, it’s about ensuring the foundations of wellness, from which the rest of good health can spring, and notably, an absence of chronic illness. In essence: enjoying chronic good health.
The prescription here is functional medicine, which stands on the shoulders of lifestyle medicine. This latter is thus briefly covered and the basics presented, but most of the book is about identifying the root causes of disease and eliminating them one by one, by taking into account the functions of the body’s processes, both in terms of pathogenesis (and thus, seeking to undermine that) and in terms of correct functioning (i.e., good health).
While the main focus of the book is on health rather than disease, he does cover a number of very common chronic illnesses, and how even in those cases where they cannot yet be outright cured, there’s a lot more that can be done for them than “take two of these and call your insurance company in the morning”, when the goal is less about management of symptoms (though that is also covered) and more about undercutting causes, and ensuring that even if one thing goes wrong, it doesn’t bring the entire rest of the system down with it (something that often happens without functional medicine).
The style is clear, simple, and written for the layperson without unduly dumbing things down.
Bottom line: if you would like glowingly good health regardless of any potential setbacks, this book can help your body do what it needs to for you.

Why Do We Have Crooked Teeth When Our Ancestors Didn’t?
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.
Evidence shows that people in ancient times typically had straight teeth set well into strong jaws, with even wisdom teeth fitting properly.
So, what went wrong? Did evolution do us a disservice?
Some information to chew on
Transition from hard-to-chew diets to processed, refined foods over millennia has reduced jaw size while tooth size stayed constant. Smaller jaws lead to tooth crowding, crookedness, and impacted wisdom teeth, requiring braces or extractions in modern times.
However, all is not lost!
Studies on non-human animals show softer diets reduce jaw and facial growth, causing dental crowding. In other words: dental crowding is primarily attributed to dietary and lifestyle changes, though genetics may play a role.
And notably, when it comes to humans, populations with less processed diets experience fewer dental problems, suggesting lifestyle modifications could help prevent tooth crowding.
And no, it is not too late. Remember, you are rebuilding your body all the time, including your bones!

Chipotle Chili Wild Rice
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 is a very gut-healthy recipe that’s also tasty and filling, and packed with polyphenols too. What’s not to love?
You will need
- 1 cup cooked wild rice (we suggest cooking it with 1 tbsp chia seeds added)
- 7 oz cooked sweetcorn (can be from a tin or from frozen or cook it yourself)
- 4 oz charred jarred red peppers (these actually benefit from being from a jar—you can use fresh or frozen if necessary, but only jarred will give you the extra gut-healthy benefits from fermentation)
- 1 avocado, pitted, peeled, and cut into small chunks
- ½ red onion, thinly sliced
- 6–8 sun-dried tomatoes, chopped
- 2 tbsp extra virgin olive oil
- 2 tsp chipotle chili paste (adjust per your heat preferences)
- 1 tsp black pepper, coarse ground
- ½ tsp MSG or 1 tsp low-sodium salt
- Juice of 1 lime
Method
(we suggest you read everything at least once before doing anything)
1) Mix the cooked rice, red onion, sweetcorn, red peppers, avocado pieces, and sun-dried tomato, in a bowl. We recommend to do it gently, or you will end up with guacamole in there.
2) Mix the olive oil, lime juice, chipotle chili paste, black pepper, and MSG/salt, in another bowl. If perchance you have a conveniently small whisk, now is the time to use it. Failing that, a fork will suffice.
3) Add the contents of the second bowl to the first, tossing gently but thoroughly to combine well, and serve.
Enjoy!

Creatine’s Brain Benefits Increase With Age
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.
Creatine is generally thought of as a body-building supplement, and for most young people, that’s all it is. But with extra years come extra advantages, and creatine starts to confer cognitive benefits. Dr. Brad Stanfield shares the science:
What the science says
Although 95% of creatine is stored in muscles, 5% is found in the brain, where it helps produce energy needed for brain processes (and that’s a lot of energy—about 20% of our body’s metabolic base rate is accounted for by our brain).
In this video, Dr. Stanfield shares studies showing creatine improving memory, especially in older adults—and also in vegetarians/vegans, since creatine is found in meat (just like in our own bodies, which are also made of meat) and not in plants. On the meta-analysis level, a systematic review concluded that creatine supplementation indeed improves memory, with stronger effects observed in older adults.
Dr. Stanfield also addresses the safety concerns about creatine, which, on balance, are not actually supported by the science (of course, always consult your own doctor to be sure, as your case could vary).
As for dosage, 5g/day is recommended. For more on all of this plus links to the studies cited, enjoy:

PFAS Exposure & Cancer: The Numbers Are High
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.
PFAS & Cancer Risk: The Numbers Are High
Image Credits Mount Sinai This is Dr. Maaike van Gerwen. Is that an MD or a PhD, you wonder? It’s both.
She’s also Director of Research in the Department of Otolaryngology at Mount Sinai Hospital in New York, Scientific Director of the Program of Personalized Management of Thyroid Disease, and Member of the Institute for Translational Epidemiology and the Transdisciplinary Center on Early Environmental Exposures.
What does she want us to know?
She’d love for us to know about her latest research published literally today, about the risks associated with PFAS, such as the kind widely found in non-stick cookware:
Per- and polyfluoroalkyl substances (PFAS) exposure and thyroid cancer risk
Dr. van Gerwen and her team tested this several ways, and the very short and simple version of the findings is that per doubling of exposure, there was a 56% increased rate of thyroid cancer diagnosis.
(The rate of exposure was not just guessed based on self-reports; it was measured directly from PFAS levels in the blood of participants)
- PFAS exposure can come from many sources, not just non-stick cookware, but that’s a “biggie” since it transfers directly into food that we consume.
- Same goes for widely-available microwaveable plastic food containers.
- Relatively less dangerous exposures include waterproofed clothing.
To keep it simple and look at the non-stick pans and microwavable plastic containers, doubling exposure might mean using such things every day vs every second day.
Practical take-away: PFAS may be impossible to avoid completely, but even just cutting down on the use of such products is already reducing your cancer risk.
Isn’t it too late, by this point in life? Aren’t they “forever chemicals”?
They’re not truly “forever”, but they do have long half-lives, yes.
See: Can we take the “forever” out of forever chemicals?
The half-lives of PFOS and PFOA in water are 41 years and 92 years, respectively.
In the body, however, because our body is constantly trying to repair itself and eliminate toxins, it’s more like 3–7 years.
That might seem like a long time, and perhaps it is, but the time will pass anyway, so might as well get started now, rather than in 3–7 years time!

What should we use instead?
In place of non-stick cookware, cast iron is fantastic. It’s not everyone’s preference, though, so you might also like to know that ceramic cookware is a fine option that’s functionally non-stick but without needing a non-stick coating. Check for PFAS-free status; they should advertise this.
In place of plastic microwaveable containers, Pyrex (or equivalent) glass dishes (you can get them with lids) are a top-tier option. Ceramic containers (without metallic bits!) are also safely microwaveable.

The Pains That Good Posture Now Can Help You Avoid Later
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. Murat Dalkilinç explains:
As a rule…
Posture is the foundation for all body movements and good posture helps the body adapt to stress.
Problems arise when poor posture causes muscles to overwork in ways that are not good for them, becoming tight or inhibited over time. Bad posture can lead to wear and tear on joints, increase accident risk, and make some organs (like the lungs, which feed everything else with the oxygen necessary for normal functioning) less efficient. It’s also of course linked to issues like scoliosis, tension headaches, and back pain, and can even affect emotions and pain sensitivity.
Good posture includes straight alignment of vertebrae when viewed from the front/back, and three natural curves in a (very!) gentle S-shape when viewed from the side. Proper posture allows for efficient movement, reduces fatigue, and minimizes muscle strain. For sitting posture, the neck should be vertical, shoulders relaxed, arms close to the body, and knees at a right angle with feet flat.
But really, one should avoid sitting, to whatever extent is reasonably possible. Standing is better than sitting; walking is better than standing. Movement is crucial, as being stationary for extended periods, even with good posture, is not good for our body.
Advices given include: adjust your environment, use ergonomic aids, wear supportive shoes, and keep moving. Regular movement and exercise keep muscles strong to support the body.
