The Diet Compass – by Bas Kast

Facts about nutrition and health can be hard to memorize. There’s just so much! And often there are so many studies, and while the science is not usually contradictory, pop-science headlines sure can be. What to believe?
Bas Kast brings us a very comprehensive and easily digestible solution.
A science journalist himself, he has gone through the studies so that you don’t have to, and—citing them along the way—draws out the salient points and conclusions.
But, he’s not just handing out directions (though he does that too); he’s arranged and formatted the information in a very readable and logical fashion. Chapter by chapter, we learn the foundations of important principles for “this is better than that” choices in diet.
Most importantly, he lays out for us his “12 simple rules for healthy eating“, and they are indeed as simple as they are well-grounded in good science.
Bottom line: if you want “one easy-reading book” to just tell you how to make decisions about your diet, simply follow those rules and enjoy the benefits… Then this book is exactly that.

Fatty Acids For The Eyes & Brain: The Good And The Bad
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.
Good For The Eyes; Good For The Brain
We’ve written before about omega-3 fatty acids, covering the basics and some lesser-known things:
What Omega-3 Fatty Acids Really Do For Us
…and while we discussed its well-established benefits against cognitive decline (which is to be expected, because omega-3 is good against inflammation, and a large part of age-related neurodegeneration is heavily related to neuroinflammation), there’s a part of the brain we didn’t talk about in that article: the eyes.
We did, however, talk in another article about supplements that benefit the eyes and [the rest of the] brain, and the important links between the two, to the point that an examination of the levels of lutein in the retina can inform clinicians about the levels of lutein in the brain as a whole, and strongly predict Alzheimer’s disease (because Alzheimer’s patients have significantly less lutein), here:
Now, let’s tie these two ideas together
In a recent (June 2024) meta-analysis of high-quality observational studies from the US and around the world, involving nearly a quarter of a million people over 40 (n=241,151), researchers found that a higher intake of omega-3 is significantly linked to a lower risk of macular degeneration.
To put it in numbers, the highest intake of omega-3s was associated with an 18% reduced risk of early stage macular degeneration.
They also looked at a breakdown of what kinds of omega-3, and found that taking a blend DHA and EPA worked best of all, although of people who only took one kind, DHA was the best “single type” option.
You can read the paper in full, here:
Association between fatty acid intake and age-related macular degeneration: a meta-analysis
A word about trans-fatty acids (TFAs)
It was another feature of the same study that, while looking at fatty acids in general, they also found that higher consumption of trans-fatty acids was associated with a higher risk of advanced age-related macular degeneration.
Specifically, the highest intake of TFAs was associated with a more than 2x increased risk.
There are two main dietary sources of trans-fatty acids:
- Processed foods that were made with TFAs; these have now been banned in a lot of places, but only quite recently, and the ban is on the processing, not the sale, so if you buy processed foods that contain ingredients that were processed before 2021 (not uncommon, given the long life of many processed foods), the chances of them having TFAs is higher.
- Most animal products. Most notably from mammals and their milk, so beef, pork, lamb, milk, cheese, and yes even yogurt. Poultry and fish technically do also contain TFAs in most cases, but the levels are much lower.
Back to the omega-3 fatty acids…
If you’re wondering where to get good quality omega-3, well, we listed some of the best dietary sources in our main omega-3 article (linked at the top of today’s).
However, if you want to supplement, here’s an example product on Amazon that’s high in DHA and EPA, following the science of what we shared today 😎
Take care!

It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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
❝Have just had microsuction to remove wax from my ears. A not unpleasant experience but would appreciate your guidance on how best to discourage the buildup of wax in the first place.❞
Well, certainly do not prod or poke it, and that includes with cotton buds (Q-Tips, for the Americans amongst us). That pushes more down than that it extracts, and creates a denser base of wax.
There is no evidence that ear candles help, and they can cause harm.
Further reading: Experts update best practices for diagnosis and treatment of earwax (cerumen impaction)
Ear drops can help, and if you want a home-remedy edition, olive oil or almond oil can be used; these oils dissolve the wax quite quickly (in fancier words: they are cerumenolytic agents); washing with water (e.g. in the shower or bath) is then all that’s needed. However, to avoid infection, ensure you are using a high-purity oil, and get one to use just for that; don’t just grab a bottle from the kitchen.
For your convenience, here is an example of medical grade almond oil (with dropper!) on Amazon
❝Every article had relevance to me. I ❤️ whole fruit, it’s my go to treat. I use ice packs to ease my arthritic knee pain, works well. I’ve read and loved Dr Gawande’s books. Great handful of almonds today❞
While this wasn’t a question, and we don’t usually publish feedback here, I (your writer here, hi) misread that as “ice picks” in the first instance, an implement we’ve probably all wanted to use to relieve pain at some point, but certainly not recommendable! Anyway, the momentary confusion made me smile, so I thought I’d share the silly thought. Smiling is infectious, and all that… And it’s certainly good for the health!
More seriously, glad you enjoyed!

Ageless Aging – by Maddy Dychtwald
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.
Maddy Dychtwald, herself 73, has spent her career working in the field of aging. She’s not a gerontologist or even a doctor, but she’s nevertheless been up-to-the-ears in the industry for decades, mostly as an organizer, strategist, facilitator, and so forth. As such, she’s had her finger on the pulse of the healthy longevity movement for a long time.
This book was written to address a problem, and the problem is: lifespan is increasing (especially for women), but healthspan has not been keeping up the pace.
In other words: people (especially women) are living longer, but often with more health problems along the way than before.
And mostly, it’s for lack of information (or sometimes: too much competing incorrect information).
Fortunately, information is something that a woman in Dychtwald’s position has an abundance of, because she has researchers and academics in many fields on speed-dial and happy to answer her questions (we get a lot of input from such experts throughout the book—which is why this book is so science-based, despite the author not being a scientist).
The book answers a lot of important questions beyond the obvious “what diet/exercise/sleep/supplements/etc are best for healthy aging” (spoiler: it’s quite consistent with the things we recommend here, because guess what, science is science), questions like how best to prepare for this that or the other, how to get a head start on preventative healthcare for some things, how to avoid being a burden to our families (one can argue that families are supposed to look after each other, but still, it’s a legitimate worry for many, and understandably so), and even how to balance the sometimes conflicting worlds of health and finances.
Unlike many authors, she also talks about the different kinds of aging, and tackles each of them separately and together. We love to see it!
Bottom line: this book is a very good one-stop-shop for all things healthy aging. It’s aimed squarely at women, but most advice goes for men the same too, aside from the section on hormones and such.

Natural alternatives to medication for depression?
Great question! We did a mean feature a while back, but we definitely have much more to say! We’ll do another main feature soon, but in the meantime, here’s what we previously wrote:
See: The Mental Health First-Aid That You’ll Hopefully Never Need
^This covers not just the obvious, but also why the most common advice is not helpful, and practical tips to actually make manageable steps back to wellness, on days when “literally just survive the day” is one’s default goal.

Acid Reflux Diet Cookbook – by Dr. Harmony Reynolds
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.
Notwithstanding the title, this is far more than just a recipe book. Of course, it is common for health-focused recipe books to begin with a preamble about the science that’s going to be applied, but in this case, the science makes up a larger portion of the book than usual, along with practical tips about how to best implement certain things, at home and when out and about.
Dr. Reynolds also gives a lot of information about such things as medications that could be having an effect one way or the other, and even other lifestyle factors such as exercise and so forth, and yes, even stress management. Because for many people, what starts as acid reflux can soon become ulcers, and that’s not good.
The recipes themselves are diverse and fairly simple; they’re written solely with acid reflux in mind and not other health considerations, but they are mostly heathy in the generalized sense too.
The style is straight to the point with zero padding sensationalism, or chit-chat. It can make for a slightly dry read, but let’s face it, nobody is buying this book for its entertainment value.
Bottom line: if you have been troubled by acid reflux, this book will help you to eat your way safely out of it.
Click here to check out the Acid Reflux Diet Cookbook, and enjoy!

The Seven Circles – by Chelsey Luger & Thosh Collins
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.
At first glance, this can seem like an unscientific book—you won’t find links to studies in this one, for sure! However, if we take a look at the seven circles in question, they are:
- Food
- Movement
- Sleep
- Ceremony
- Sacred Space
- Land
- Community
Regular 10almonds readers may notice that these seven items contain five of the things strongly associated with the “supercentenarian Blue Zones”. (If you are wondering why Native American reservations are not Blue Zones, the answer there lies less in health science and more in history and sociology, and what things have been done to a given people).
The authors—who are Native American, yes—present in one place a wealth of knowledge and know-how. Not even just from their own knowledge and their own respective tribes, but gathered from other tribes too.
Perhaps the strongest value of this book to the reader is in the explanation of noting the size of each of those circles, how they connect with each other, and providing a whole well-explained system for how we can grow each of them in harmony with each other.
Or to say the same thing in sciencey terms: how to mindfully improve integrated lifestyle factors synergistically for greater efficacy and improved health-adjusted quality-of-life years.
Bottom line: if you’re not averse to something that mostly doesn’t use sciencey terms of have citations to peer-reviewed studies peppered through the text, then this book has wisdom that’s a) older than the pyramids of Giza, yet also b) highly consistent with our current best science of Blue Zone healthy longevity.
