Brain Food? The Eyes Have It!

This is Dr. Michael Greger, M.D. FACLM, of “Dr. Greger’s Daily Dozen” and “How Not To Die” fame, and he wants us to protect our brains (and while we’re at it, our eyesight).
And the secret is…
Lutein.
This is a carotenoid, which is super important for the eyes and brain. Not to be confused with carrots, which despite the name are usually not a good source of carotenoids!
They do however contain lots of beta-carotene, a form of vitamin A, but that (and the famous WW2-era myth born of deliberate disinformation by the British government) isn’t what we’re covering today.
We say “eyes and brain” but really, the eyes are just an extension of the brain in any case.
Pedantry aside, what Dr. Greger wants you to know about lutein is how important it is for the protection of your brain/eyes, both against cognitive decline and against age-related macular degeneration (the most common cause of eyesight loss in old age).
Important take-away info:
- Two things that hasten brain aging are inflammation and oxidative stress. Antioxidant and anti-inflammatory foods mitigate those.
- Researchers investigated eight different dietary antioxidants, including vitamins A and E. Only lutein was “significantly related to better cognition”.
- The macula in the middle of our retina is packed with lutein, and levels in the retina correspond to levels in the rest of our brain.
- Alzheimer’s patients have significantly less lutein in their eyes and in their blood, and a higher occurrence of macular degeneration.
- Dark green leafy vegetables are lutein superstars. A half cup of kale has 50 times more lutein than an egg.

Exhausted To Energized – by Dr. Libby Weaver
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 very many possible causes of low energy; some are obvious; some are not.
Dr. Weaver goes through a comprehensive list that goes beyond the common, to encompass also the “not rare” options—how to test for them where appropriate, and how to improve/fix them where appropriate.
Thus, she talks us through the marvels of mitochondria (including how to keep them happy and healthy and how to promote the generation of new ones), antioxidant defense mechanisms, coenzyme Q10 and friends, B vitamins of various kinds, macronutrients, the autonomic nervous system, sleep and its many factors, blood oxygenation, digestive issues, what’s going on in the spleen, the gallbladder, the liver, the kidneys, the adrenal glands, our thyroid goings-on in all its multifarious wonders, minerals like iodine, iron, magnesium, zinc, our epigenetic factors, and even psychological considerations ranging from stress to grief. In short—and we have shortened the list to pick out particularly salient points—quite a comprehensive rundown of the human body to make your human body less run-down.
The style is on the very readable pop-science, and/but she does bring her professional knowledge to bear on topic (her doctorate is a PhD in biochemistry, and it shows; a lot of explanations come from that angle).
Bottom line: if you are often exhausted and would rather be energized, this this book almost certainly address at least a couple of things you probably haven’t considered—and even just one would make it worthwhile.

How Processed Is The Food You Buy, Really?
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.
Ultraprocessed foods are a) ubiquitous in industrialized nations b) generally not fabulous for the health. See for example:
- Eat To Beat Cancer ← skipping the ultraprocessed foods is one main point
- What To Leave Off Your Table (To Stay Off This Surgeon’s) ← have a guess
Abstaining from ultraprocessed food can also be difficult psychologically, because they are generally engineered specifically to trigger certain physiological responses, often with their combination of sweet and/or salty flavors with simple carbohydrates that will zip straight into one’s veins and feel immediately rewarding, even if there is a health price to pay later.
And worse, being habituated to ultraprocessed food can make unprocessed or minimally-processed food seem less appealing:
What causes food cravings? And what can we do about them?
Fortunately, we can reverse this, and once we get habituated to unprocessed or minimally-processed food, the ultraprocessed will start to seem like not-food to us. You will wonder: how did I ever eat that crap?
Now, one other thing to bear in mind:
There is a scale of “badness”
You might recall this article:
Not all ultra-processed foods are bad for your health, whatever you might have heard
For example, Reese’s confectionary and Huel nutrition powder are both ultra-processed, but one is definitely better than the other.
See also: Are plant-based burgers really bad for your heart? Here’s what’s behind the scary headlines
Some comparisons are obvious; others, not so much. So, how to tell the difference?
The “True Food” Scale
A large study analyzed ingredient lists, nutrition facts, and prices of over 50,000 food items from Target, Whole Foods, and Walmart. Using a rigorous statistical method, they assigned processing scores and compiled data into a giant database, with results published publicly.
You can find the study here:
Prevalence of processed foods in major US grocery stores
That in and of itself doesn’t tell a lot that’s useful to the consumer, because the paper itself does not have all of the data from all 50,000 food items, just the aggregate results, trends, implications for public health, and suggestions for public health policy.
However, what does tell a lot, is the public face of the database itself, which you can browse for free, and look up your regular shopping items, if you are wondering “are these textured soy pieces basically a step away from soy beans, or a frankenfood that will murder me in my sleep?”
How it works: it examines each food, its listed ingredients, and what is known about the processedness of such ingredients. It also draws a distinction between ingredients and additives, rendering the entire process of the production of the food into an “ingredient tree”, showing what was added to what along the way. Minimally-processed foods will have barely an ingredient sapling, while ultraprocessed foods will have an ingredient tree whose branches can barely be counted, they are so numerous. It’s not just about the number of ingredients though; it’s about the processes that each underwent.
How it represents this data: you can look at the food in the database, and it’ll tell you the ingredients and nutritional facts (which you probably knew already; it’s written on the packaging), and then show you how processed it is, and then ranking that against all other foods in the database of the same kind.
So for example, if you are looking at a pizza (have you ever noticed how some are marketed with bright flashy colors, and others in natural tones to suggest minimal processing? This is marketing, not reliable information! Sometimes the product that looks healthier, isn’t!), then it’ll give it a score reflecting how it ranks compared to all other pizze in the database. This number is out of a hundred, and it reflects the percentile into which it falls.
So for example, if the score your pizza gets is 47, then that means that if you looked at it next to 99 others, on average your pizza would would rank better than 46 of them and worse than 53 of them.
In other words, the lower the score, the less processed it is on the whole.
Here’s a side-by-side example of two cakes, one of which got a score of 3, and the other got a score of 61:
Mini No Sugar Added Cheesecake vs EDWARDS Desserts Original Whipped Cheesecake
And here is the main menu of the database, in which you can use the search function to look up the food you want to check, or else browse by category:
The TrueFood Database: Search or Browse (it’s free!)
Enjoy!

‘Tis To Season To Be SAD-Savvy

Seasonal Affective Disorder & SAD Lamps
For those of us in the Northern Hemisphere, it’s that time of the year; especially after the clocks recently went back and the nights themselves are getting longer. So, what to do in the season of 3pm darkness?
First: the problem
The problem is twofold:
- Our circadian rhythm gets confused
- We don’t make enough serotonin
The latter is because serotonin production is largely regulated by sunlight.
People tend to focus on item 2, but item 1 is important too—both as problem, and as means of remedy.
Circadian rhythm is about more than just light
We did a main feature on this a little while back, talking about:
- What light/dark does for us, and how it’s important, but not completely necessary
- How our body knows what time it is even in perpetual darkness
- The many peaks and troughs of many physiological functions over the course of a day/night
- What that means for us in terms of such things as diet and exercise
- Practical take-aways from the above
Read: The Circadian Rhythm: Far More Than Most People Know
With that in mind, the same methodology can be applied as part of treating Seasonal Affective Disorder.
Serotonin is also about more than just light
Our brain is a) an unbelievably powerful organ, and the greatest of any animal on the planet b) a wobbly wet mass that gets easily confused.
In the case of serotonin, we can have problems:
- knowing when to synthesize it or not
- synthesizing it
- using it
- knowing when to scrub it or not
- scrubbing it
- etc
Selective Serotonin Re-uptake Inhibitors (SSRIs) are a class of antidepressants that, as the name suggests, inhibit the re-uptake (scrubbing) of serotonin. So, they won’t add more serotonin to your brain, but they’ll cause your brain to get more mileage out of the serotonin that’s there, using it for longer.
So, whether or not they help will depend on you and your brain:

How useful are artificial sunlight lamps?
Artificial sunlight lamps (also called SAD lamps), or blue light lamps, are used in an effort to “replace” daylight.
Does it work? According to the science, generally yes, though everyone would like more and better studies:
- The Efficacy of Light Therapy in the Treatment of Seasonal Affective Disorder: A Meta-Analysis of Randomized Controlled Trials
- Blue-Light Therapy for Seasonal and Non-Seasonal Depression: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Interestingly, it does still work in cases of visual impairment and blindness:
How much artificial sunlight is needed?
According to Wirz-Justice and Terman (2022), the best parameters are:
- 10,000 lux
- full spectrum (white light)
- 30–60 minutes exposure
- in the morning
Source: Light Therapy: Why, What, for Whom, How, and When (And a Postscript about Darkness)
That one’s a fascinating read, by the way, if you have time.
Can you recommend one?
For your convenience, here’s an example product on Amazon that meets the above specifications, and is also very similar to the one this writer has

Healthy Kids, Happy Kids – by Dr. Elisa Song
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.
If you have young children or perhaps grandchildren, you probably care deeply about those children and their wellbeing, but there can often be a lot more guesswork than would be ideal, when it comes to ensuring they be and remain healthy.
Nevertheless, a lot of common treatments for children are based (whether parents know it or not—and often they dont) on what is most convenient for the parent, not necessarily what is best for the child. Dr. Song looks to correct that.
Rather than dosing kids with acetaminophen or even antibiotics, assuming eczema can be best fixed with a topical cream (treating the symptom rather than the cause, much?), and that some things like asthma “just are”, and “that’s unfortunate”, Dr. Song takes us on a tour of pediatric health, centered around the gut.
Why the gut? Well, it’s pretty central to us as adults, and it’s the same for kids, except one difference: their gut microbiome is changing even more quickly than ours (along with the rest of their body), and as such, is even more susceptible to little nudges for better or for worse, having a big impact in either direction. So, might as well make it a good one!
After an explanatory overview, most of the book is given over to recognizing and correcting what things can go wrong, including the top 25 acute childhood conditions, and the most critical chronic ones, and how to keep things on-track as a team (the child is part of the team! An important part!).
The style of the book is very direct and instructional; easy to understand throughout. It’s a lot like being in a room with a very competent pediatrician who knows her stuff and explains it well, thus neither patronizing nor mystifying.
Bottom line: if there are kids in your life, be they yours or your grandkids or someone else, this is a fine book for giving them the best foundational health.

Five Advance Warnings of Multiple Sclerosis
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.
Five Advance Warnings of Multiple Sclerosis
First things first, a quick check-in with regard to how much you know about multiple sclerosis (MS):
- Do you know what causes it?
- Do you know how it happens?
- Do you know how it can be fixed?
If your answer to the above questions is “no”, then take solace in the fact that modern science doesn’t know either.
What we do know is that it’s an autoimmune condition, and that it results in the degradation of myelin, the “insulator” of nerves, in the central nervous system.
- How exactly this is brought about remains unclear, though there are several leading hypotheses including autoimmune attack of myelin itself, or disruption to the production of myelin.
- Treatments look to reduce/mitigate inflammation, and/or treat other symptoms (which are many and various) on an as-needed basis.
If you’re wondering about the prognosis after diagnosis, the scientific consensus on that is also “we don’t know”:
Read: Personalized medicine in multiple sclerosis: hope or reality?
this paper, like every other one we considered putting in that spot, concludes with basically begging for research to be done to identify biomarkers in a useful fashion that could help classify many distinct forms of MS, rather than the current “you have MS, but who knows what that will mean for you personally because it’s so varied” approach.
The Five Advance Warning Signs
Something we do know! First, we’ll quote directly the researchers’ conclusion:
❝We identified 5 health conditions associated with subsequent MS diagnosis, which may be considered not only prodromal but also early-stage symptoms.
However, these health conditions overlap with prodrome of two other autoimmune diseases, hence they lack specificity to MS.❞
So, these things are a warning, five alarm bells, but not necessarily diagnostic criteria.
Without further ado, the five things are:
- depression
- sexual disorders
- constipation
- cystitis
- urinary tract infections
❝This association was sufficiently robust at the statistical level for us to state that these are early clinical warning signs, probably related to damage to the nervous system, in patients who will later be diagnosed with multiple sclerosis.
The overrepresentation of these symptoms persisted and even increased over the five years after diagnosis.❞

An Apple (Cider Vinegar) A Day…
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.
An Apple (Cider Vinegar) A Day…
You’ve probably heard of people drinking apple cider vinegar for its health benefits. It’s not very intuitive, so today we’re going to see what the science has to say…
Apple cider vinegar for managing blood sugars
Whether diabetic, prediabetic, or not at all, blood sugar spikes aren’t good for us, so anything that evens that out is worth checking out. As for apple cider vinegar…
Diabetes Control: Is Vinegar a Promising Candidate to Help Achieve Targets?
…the answer found by this study was “yes”, but their study was small, and they concluded that more research would be worthwhile. So…
…was also a small study, with the same (positive) results.
But! We then found a much larger systematic review was conducted, examining 744 previously-published papers, adding in another 14 they found via those. After removing 47 duplicates, and removing another 15 for not having a clinical trial or not having an adequate control, they concluded:
❝In this systematic review and meta-analyses, the effect of vinegar consumption on postprandial glucose and insulin responses were evaluated through pooled analysis of glucose and insulin AUC in clinical trials. Vinegar consumption was associated with a statistically significant reduction in postprandial glucose and insulin responses in both healthy participants and participants with glucose disorder.❞
~ Sishehbor, Mansoori, & Shirani
Check it out:
Apple cider vinegar for weight loss?
Yep! It appears to be an appetite suppressant, probably moderating ghrelin and leptin levels.
But…
As a bonus, it also lowers triglycerides and total cholesterol, while raising HDL (good cholesterol), and that’s in addition to doubling the weight loss compared to control:
How much to take?
Most of these studies were done with 1–2 tbsp of apple cider vinegar in a glass of water, at mealtime.
Obviously, if you want to enjoy the appetite-suppressant effects, take it before the meal! If you forget and/or choose to take it after though, it’ll still help keep your blood sugars even and still give you the cholesterol-moderating benefits.
Where to get it?
Your local supermarket will surely have it. Or if you buy it online, you can even get it in capsule form!
