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:

Pistachios vs Brazil Nuts – 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 Brazil nuts, we picked the pistachios.
Why?
In terms of macros, pistachios have more protein, carbs, and fiber, while Brazil nuts have more fat. The fats are mostly healthy, although it is worth noting that Brazil nuts have not only more total saturated fat, but also more saturated fat proportionally to total fats. All in all, Brazil nuts’ macro balance isn’t bad, but we say pistachios have it better.
When it comes to vitamins, pistachios have a lot more of vitamins A, B1, B2, B3, B5, B6, B7, B9, and C, while Brazil nuts have more vitamin E. An easy win for pistachios here.
In the category of minerals, it gets interesting: pistachios have more iron and potassium, while Brazil nuts have more calcium, copper, magnesium, phosphorus, selenium, and zinc. Sounds great, but… About that selenium:
- A cup of cashews contains 38% of the RDA of selenium. This will go towards helping your hair be luscious and shiny (also important for energy conversion).
- A cup of Brazil nuts contains 10,456% of the RDA of selenium. This is way past the point of selenium toxicity, and your (luscious, shiny) hair will fall out.
For this reason, it’s recommended to eat no more than 3–4 Brazil nuts per day.
We consider that a point against Brazil nuts.
Adding up the sections gives us an overall win for pistachios. Of course, enjoy Brazil nuts too if you will, but in careful moderation please!

Radical Longevity – by Dr. Ann Gittleman
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. Gittleman takes a comprehensive approach, advising us about avoiding AGEs, freeing up fascia, stimulating cellular rejuvenation, the mind-gut connection, keeping the immune system healthy, and more.
The “plan” promised by the subtitle involves identifying the key factors of nutrition and lifestyle most impactful to you, and adjusting them accordingly, in a multistep, author-walks-the-reader-by-the-hand process.
There’s also, for those who prefer it, a large section (seven chapters) on a body part/system by body part/system approach, e.g. brain health, heart health, revitalizing skin, reversing hair loss, repairing bones, muscles, joints, etc.
The writing style is quite casual,butalso with a mind to education, with its call-out boxes, bullet-point summaries, and so forth. There is a “select references” section, but if one wants to find studies, it’s often necessary to go looking, as there aren’t inline citations.
Bottom line: we’d love to see better referencing, but otherwise this is a top-tier anti-aging book, and a lot more accessible than most, without skimping on depth and breadth.

Beating Toxic Positivity
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.
How To Get Your Brain On A More Positive Track (Without Toxic Positivity)
There have been many studies done regards optimism and health, and they generally come to the same conclusion: optimism is simply good for the health.
Here’s an example we’ve mentioned before, but it’s a good introduction to today’s main feature. It’s a longitudinal study, and it followed 121,700 women (what a sample size!) for eight years. It controlled for all kinds of other lifestyle factors (especially smoking, drinking, diet, and exercise habits, as well as pre-existing medical conditions), so this wasn’t a case of “people who are healthy are more optimistic as results. And, in the researchers’ own words…
❝We found strong and statistically significant associations of increasing levels of optimism with decreasing risks of mortality, including mortality due each major cause of death, such as cancer, heart disease, stroke, respiratory disease, and infection. Importantly, findings were maintained after close control for potential confounding factors, including sociodemographic characteristics and depression❞
Read: Optimism and Cause-Specific Mortality: A Prospective Cohort Study
And yet, toxic positivity can cause as many problems as it tries to fix.
What is toxic positivity?
- Toxic positivity is the well-meaning friend who says “I’m sure it’ll be ok” when you know full well it definitely will not.
- Toxic positivity is the allegorical frog-in-a-pan saying that the temperature rises due to climate change are gradual, so they’re nothing to worry about
- Toxic positivity is thinking that “good vibes” will outperform chemotherapy
Sometimes, a dose of realism is needed. So, can we do that and maintain a positive attitude?
The answer is: somewhat, yes! But first, a quick check-in:
❝I’m not a pessimist; I’m a realist!❞
~ every pessimist ever
To believe self-reports, the world is divided between optimists and realists. But how does your outlook measure up, really?
While like most free online tests, this is offered “as-is” with the usual caveats about not being a clinical diagnostic tool, this one actually has a fair amount of scientific weight behind it:
❝Empirical testing has indicated the validity of the Optimism Pessimism Instrument as published in the scientific journal Current Psychology: Research and Reviews.
The IDRlabs Optimism/Pessimism Test (IDR-OPT) was developed by IDRlabs. The IDR-OPT is based on the Optimism/Pessimism Instrument (OPI) developed by Dr. William Dember, Dr. Stephanie Martin, Dr. Mary Hummer, Dr. Steven Howe, and Dr. Richard Melton, at the University of Cincinnati.❞
Take This Short (1–2 mins) Test
How did you score? And what could you do to improve on that score?
First, it’s said that with a big enough “why”, one can overcome any “how”. So…
An attitude of gratitude
We know, we know, it’s very Oprah Winfrey. But also, it works. Take the time, ideally daily, to quickly list 3–5 things for which you feel grateful. Great or small, it can be anything from your spouse to your cup of coffee, provided you feel fortunate to have it.
How this works: our brains easily get stuck in loops, so it can help to nudge them into a more positive loop.
What about when we are treated unfairly? Are we supposed to be grateful?
Sometimes, our less positive emotions are necessary, to protect us and/or those around us, and to provide a motivational force. We can still maintain a positive attitude by noting the bad thing and some good, but watch out! Notice the difference:
- “How dare they take our healthcare away, but at least I’m not sick right now” (lasting impression: no action required)
- “At least I’m not sick right now, but how dare they take our healthcare away!” (lasting impression: action required)
It’s a well-known idea in neurolinguistic programming, that “but” negates whatever goes before it (think of “I’m sorry but”, or “I’m not racist but”, etc), so use it consciously and wisely, or else simply use “and” instead.
Cognitive reframing: problem, or opportunity?
Most problems can be opportunities, even if the problems themselves genuinely suck and are not intrinsically positive. A way of leveraging this can be replacing “I have to…” with “I get to…”.
This not only can reframe problems as opportunities, but also calls back to the gratitude idea.
- Instead of “I have to get my mammogram / prostate exam” (not generally considered fun activities), “I get to have the peace of mind of being free from cancer / I get to have the forewarning that will keep me safe”.
- Instead of “I have to go to work”, “I get to go to work” (many wish they were in your shoes!)
- Instead of “I have to rest”, “I get to rest”
When things are truly not great
Whether due to internal or external factors, whether you can control something or not, sometimes things are truly not great. The trick here is that in most contexts, one can replace negative talk, with verbally positive talk, no matter how dripping with scathing irony. You’ll still get to express the idea you wanted, but your brain will feel more positive and you’ll be in a positive loop rather than a negative one.
This, by the way, is the inverse of talking to a dog with a tone of voice that is completely the opposite of the meaning of the words. Whereas the dog will interpret the tone only, your brain will interpret the words only.
- You just spilled your drink over yourself at a social function? “Aren’t I the very model of grace and charm?”
- You made a costly mistake in your business dealings? “I am such a genius”
- You just got a diagnosis of a terrible disease? “Well, this is fabulous”
None of these things involve burying your head in the sand, in the manner of toxic positivity. You’ll still learn from your business mistake and correct it as best you can, or take appropriate action regards the disease, for example.
You’ll just feel better while you do it, and not get caught into a negative spiral that ruins your day, or even your next few months.
Sympathetic/Somatic Therapy:
Lastly, an easy one, leveraging the body’s tendency to get in sync with things around us:
For when you do just need a mood change, have an uplifting playlist available at the touch of a button. It’s hard to be consumed with counterproductive feelings to the tune of “Walking on Sunshine”!
Bonus tip: consider having the playlist start with something that is lyrically negative while musically upbeat. That way, your brain won’t resist it as antithetical to your mood, and by the second track, you’ll already be on your way to a better mood.

Food and Nutrition – by Dr. P.K. Newby
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.
The “What Everyone Needs To Know” part of the title is the name of a series of books, of which this one, “Food and Nutrition”, is one.
In this case, the title is apt, and/or could have been “What Everyone Really Should Know”, or “What Everyone Would Like To Think They Know But Have Often Just Been Bluffing Their Way Through The Supermarket Aisles”.
The chapter and section headings are all in the forms of questions, such that all-together in such volume in the table of contents, they’re reminiscent of the “Jonathan Frakes Asks You Things” meme.
But, this serves a dual purpose—for one, it makes the whole book one big FAQ, which is a very convenient format. Furthermore, it prompts a little thought on the part of the reader before each section, if we indeed question for ourselves:
- Are fertilizers in farming friend or foe?
- How have the Digital Revolution and Information Age impacted our diet?
- Are canned and frozen foods inferior to fresh?
- Does snacking or meal timing matter?
- What are cereal grains and “pseudograins”?
…And so many more. But what’s best about this is:
Dr. Newby doesn’t reference her own preferences, or even have a particular way of eating she’d like us to adopt. She just lays out the science to answer each question, as discovered by high-quality studies and a general weight of evidence.
Bottom line: this book can level-up your nutritional knowledge from bluffing to really knowing! A worthy addition to anyone’s bookshelf.

Feel Great, Lose Weight – by Dr. Rangan Chatterjee
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 all know that losing weight sustainably tends to be harder than simply losing weight. We know that weight loss needs to come with lifestyle change. But how to get there?
One of the biggest problems that we might face while trying to lose weight is that our “metabolic thermostat” has got stuck at the wrong place. Trying to move it just makes our bodies think we are starving, and everything gets even worse. We can’t even “mind over matter” our way through it with willpower, because our bodies will do impressive things on a cellular level in an attempt to save us… Things that are as extraordinary as they are extraordinarily unhelpful.
Dr. Rangan Chatterjee is here to help us cut through that.
In this book, he covers how our metabolic thermostat got stuck in the wrong place, and how to gently tease it back into a better position.
Some advices won’t be big surprises—go for a whole foods diet, avoiding processed food, for example. Probably not a shocker.
Others are counterintuitive, but he explains how they work—exercising less while moving more, for instance. Sounds crazy, but we assure you there’s a metabolic explanation for it that’s beyond the scope of this review. And there’s plenty more where that came from, too.
Bottom line: if your weight has been either slowly rising, or else very stable but at a higher point than you’d like, Dr. Chatterjee can help you move the bar back to where you want it—and keep it there.

Healthy Heart, Healthy Brain – by Dr. Bradley Bale & Dr. Amy Doneen
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 often written that “what’s good for your heart is good for your brain”, because the former feeds the latter and takes away detritus. You cannot have a healthy brain without a healthy heart.
This book goes into that in more detail than we have ever had room to here! This follows from their previous book “Beat The Heart Attack Gene”, but we’re jumping in here because that book doesn’t really contain anything not also included in this one.
The idea is the same though: it is the authors’ opinion that far too many interventions are occurring far too late, and they want to “wake everyone up” (including their colleagues in the field) to encourage earlier (and broader!) testing.
Fun fact: that also reminded this reviewer that she had a pending invitation for blood tests to check these kinds of things—phlebotomy appointment now booked, yay!
True the spirit of such exhortation to early testing, this book does include diagnostic questionnaires, to help the reader know where we might be at. And, interestingly, while the in-book questionnaire format of “so many points for this answer, so many for that one”, etc is quite normal, what they do differently in the diagnostics is that in cases of having to answer “I don’t know”, it assigns the highest-risk point value, i.e. the test will err on the side of assume the worst, in the case of a reader not knowing, for example, what our triglycerides are like. Which, when one thinks about it, is probably a very sensible reasoning.
There’s a lot of advice about specific clinical diagnostic tools and things to ask for, and also things that may raise an alarm that most people might overlook (including doctors, especially if they are only looking for something else at the time).
You may be wondering: do they actually give advice on what to actually do to improve heart and brain health, or just how to be aware of potential problems? And the answer is that the latter is a route to the former, and yes they do offer comprehensive advice—well beyond “eat fiber and get some exercise”, and even down to the pros and cons of various supplements and medications. When it comes to treating a problem that has been identified, or warding off a risk that has been flagged, the advice is a personalized, tailored, approach. Obviously there’s a limit to how much they can do that in the book, but even so, we see a lot of “if this then that” pointers to optimize things along the way.
The style is… a little salesy for this reviewer’s tastes. That is to say, while it has a lot of information of serious value, it’s also quite padded with self-congratulatory anecdotes about the many occasions the authors have pulled a Dr. House and saved the day when everyone else was mystified or thought nothing was wrong, the wonders of their trademarked methodology, and a lot of hype for their own book, as in, the book that’s already in your hands. Without all this padding, the book could have been cut by perhaps a third, if not more. Still, none of that takes away from the valuable insights that are in the book too.
Bottom line: if you’d like to have a healthier heart and brain, and especially if you’d like to avoid diseases of those two rather important organs, then this book is a treasure trove of information.
