It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
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
❝So its normal to develop a white sort of coating on the tongue, right? It develops when I eat, and is able to (somewhat) easily be brushed off❞
If (and only if) there is no soreness and the coverage of the whiteness is not extreme, then, yes, that is normal and fine.
Your mouth has a microbiome, and it’s supposed to have one (helps keep the conditions in your mouth correct, so that food is broken down and/but your gums and teeth aren’t).
Read more: The oral microbiome: Role of key organisms and complex networks in oral health and disease
The whiteness you often see on a healthy tongue is, for the most part, bacteria and dead cells—harmless.
Cleaning the whiteness off with your brush is fine. You can also scrape off with floss is similar if you prefer. Or a tongue-scraper! Those can be especially good for people for whom brushing the tongue is an unpleasant sensation. Or you can just leave it, if it doesn’t bother you.
By the way, that microbiome is a reason it can be good to go easy on the mouthwash. Moderate use of mouthwash is usually fine, but you don’t want to wipe out your microbiome then have it taken over by unpleasantries that the mouthwash didn’t kill (unpleasantries like C. albicans).
There are other mouthwash-related considerations too:
Toothpastes and mouthwashes: which kinds help, and which kinds harm?
If you start to get soreness, that probably means the papillae (little villi-like things) are inflamed. If there is soreness, and/or the whiteness is extreme, then it could be a fungal infection (usually C. albicans, also called Thrush), in which case, antifungal medications will be needed, which you can probably get over the counter from your pharmacist.
Do not try to self-treat with antibiotics.
Antibiotics will make a fungal infection worse (indeed, antibiotic usage is often the reason for getting fungal growth in the first place) by wiping out the bacteria that normally keep it in check.
Other risk factors include a sugary diet, smoking, and medications that have “dry mouth” as a side effect.

If you have any symptoms more exciting than the above, then definitely see a doctor.
Take care!

End Your Carb Confusion – by Dr. Eric Westman & Amy Berger
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.
Carbs can indeed be confusing! We’ve written about it ourselves before, but there’s more to be said than fits in a single article, and sometimes a book is in order. This one is such a book.
The authors (an MD and a nutritionist) explain the ins and outs of carbohydrates of various kinds, insulin responses, and what that means for the body. They also then look at the partly-similar, partly-different processes that occur with the metabolism of fats of various kinds, and what that means for the body, too.
Ultimately they advocate for a simple and clear low-carb approach broadly consistent with keto diet macro principles, without getting too overly focused on “is this fruit/vegetable ok?” minutiae. This has the benefit of putting it well aside from the paleo diet, for example (which focuses more on pseudo-historical foods than it does on macros), and also makes it a lot easier on a practical level.
The style is very textbook-like, which makes for an easy read with plenty of information that should stick easily in most reader’s minds, rather than details getting lost in wall-of-text formatting. So, we approve of this.
There is not, by the way, a recipes section. It’s “here’s the information, now go forth and enjoy” and leaves us all to find/make our own recipes, rather than trying to guess our culinary preferences.
Bottom line: if you’d like an easy-to-read primer on understanding how carbs work, what it means for you, and what to do about it, then this is a fine book.

Do Breathe – by Michael Williams
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.
Have you ever felt you could get everything in your life in order, if you could just get a little breathing room first?
Notwithstanding the title, this is mostly not a book about breathing exercises. It does cover that too, but there’s a lot more.
The author’s advices draw from a variety of high quality sources. Well-read readers will certainly recognise sections that are straight from David Allen’s “Getting Things Done”, and Mihaly Czikszentmihalyi’s “Flow”, for example, as well as Francesco Cirillo’s “Pomodoro Technique”, and James Clear’s “Atomic Habits”.
We also learn about how even simple yoga can help us, and good sleep, and a healthy diet.
In short, if you’ve been reading 10almonds for a while, you might not actually learn much new! But it’s very nice to have all these things in one book, for sure, and it’s a pleasant, easy read too.
Bottom line: if you’d like to streamline your life and not have to buy a whole stack of different books to do it, this book is a great composite that will enable you to get the job done efficiently.

The Coffee-Cortisol Connection, And Two Ways To Tweak It For Health
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.
Health opinions on coffee vary from “it’s an invigorating, healthful drink” to “it will leave you a shaking frazzled wreck”. So, what’s the truth and can we enjoy it healthily? Dr. Alan Mandell weighs in:
Enjoy it, but watch out!
Dr. Mandell is speaking only for caffeinated coffee in this video, and to this end, he’s conflating the health effects of coffee and caffeine. A statistically reasonable imprecision, since most people drink coffee with its natural caffeine in, but we’ll make some adjustment to his comments below, to disambiguate which statements are true for coffee generally, and which are true for caffeine:
- Drinking
coffeecaffeine first thing in the morning may not be ideal due to dehydration from overnight water loss. Coffeecaffeine is a diuretic, which means an increase in urination, thus further dehydrating the body.- Coffee contains great antioxidants, which are of course beneficial for the health in general.
- Cortisol, the body’s stress hormone, is generally at its peak in the morning. This is, in and of itself, good and correct—it’s how we wake up.
Coffeecaffeine consumption raises cortisol levels even more, leading to increased alertness and physical readiness, but it is possible to have too much of a good thing, and in this case, problems can arise because…- Elevated cortisol from early
coffeecaffeine drinking can build tolerance, leading to the need for morecoffeecaffeine over time. - It’s better, therefore, to defer drinking
coffeecaffeine until later in the morning when cortisol levels naturally drop. - All of this means that drinking
coffeecaffeine first thing can disrupt the neuroendocrine system, leading to fatigue, depression, and general woe. - Hydrate first thing in the morning before consuming
coffeecaffeine to keep the body balanced and healthy.
What you can see from this is that coffee and caffeine are not, in fact, interchangeable words, but the basic message is clear and correct: while a little spike of cortisol in the morning is good, natural, and even necessary, a big spike is none of those things, and caffeine can cause a big spike, and since for most people caffeine is easy to build tolerance to, there will indeed consistently be a need for more, worsening the problem.
In terms of hydration, it’s good to have water (or better yet, herbal tea) on one’s nightstand to drink when one wakes up.
If coffee is an important morning ritual for you, consider finding a good decaffeinated version for at least your first cup (this writer is partial to Lavazza’s “Dek Intenso”—which is not the same as their main decaf line, by the way, so do hold out for the “Dek Intenso” if you want to try my recommendation).
Decaffeinated coffee is hydrating and will not cause a cortisol spike (unless for some reason you find coffee as a concept very stressful in which case, yes, the stressor will cause a stress response).
Anyway, for more on all of this, enjoy:

Can Saturated Fats Be Healthy?
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.
Saturated Fat: What’s The Truth?
We asked you for your health-related opinion of saturated fat, and got the above-pictured, below-described, set of results.
- Most recorded votes were for “Saturated fat is good, but only some sources, and/or in moderation”
- This is an easy one to vote for, because of the “and/or in moderation” part, which tends to be a “safe bet” for most things.
- Next most popular was “Saturated fat is terrible for the health and should be avoided”
- About half as many recorded votes were for “I’m not actually sure what makes saturated fat different”, which is a very laudable option to click. Admitting when we don’t know things (and none of us know everything) is a very good first step to learning about them!
- Fewest recorded votes were for “Saturated fat is the best source of energy; we should get plenty”.
So, what does the science say?
First, a bit of physics, chemistry, and biology
You may be wondering what, exactly, saturated fats are “saturated” with. That’s a fair question, so…
All fats have a molecular structure made up of carbon, hydrogen, and oxygen atoms. Saturated fats are saturated with hydrogen, and thus have only single bonds between carbon atoms (unsaturated fats have at least one double-bond between carbon atoms).
The observable effect this has on them, is that fats that are saturated with hydrogen are solid at room temperature, whereas unsaturated fats are liquid at room temperature. Their different properties also make for different interactions inside the human body, including how likely or not they are to (for example) clog arteries.
See also: Could fat in your bloodstream cause blood clots?
Saturated fat is the best source of energy; we should get plenty: True or False?
False, in any reasonable interpretation, anyway. That is to say, if your idea of “plenty” is under 13g (e.g: two tablespoons of butter, and no saturated fat from other sources, e.g. meat) per day, then yes, by all means feel free to eat plenty. More than that, though, and you might want to consider trimming it down a bit.
The American Heart Association has this to say:
❝When you hear about the latest “diet of the day” or a new or odd-sounding theory about food, consider the source.
The American Heart Association recommends limiting saturated fats, which are found in butter, cheese, red meat and other animal-based foods, and tropical oils.
Decades of sound science has proven it can raise your “bad” cholesterol and put you at higher risk for heart disease.❞
Source: The American Heart Association Diet and Lifestyle Recommendations on Saturated Fat
The British Heart Foundation has a similar statement:
❝Despite what you read in the media, our advice is clear: replace saturated fats with unsaturated fats and avoid trans fats. Saturated fat is the kind of fat found in butter, lard, ghee, fatty meats and cheese. This is linked to an increased risk of heart and circulatory disease❞
Source: British Heart Foundation: What does fat do and what is saturated fat?
As for the World Health Organization:
❝1. WHO strongly recommends that adults and children reduce saturated fatty acid intake to 10% of total energy intake
2. WHO suggests further reducing saturated fatty acid intake to less than 10% of total energy intake
3. WHO strongly recommends replacing saturated fatty acids in the diet with polyunsaturated fatty acids; monounsaturated fatty acids from plant sources; or carbohydrates from foods containing naturally occurring dietary fibre, such as whole grains, vegetables, fruits and pulses.❞
Source: Saturated fatty acid and trans-fatty acid intake for adults and children: WHO guideline
Please note, organizations such as the AHA, the BHF, and the WHO are not trying to sell us anything, and just would like us to not die of heart disease, the world’s #1 killer.
As for “the best source of energy”…
We evolved to eat (much like our nearest primate cousins) a diet consisting mostly of fruits and other edible plants, with a small supplementary amount of animal-source protein and fats.
That’s not to say that because we evolved that way we have to eat that way—we are versatile omnivores. But for example, we are certainly not complete carnivores, and would quickly sicken and die if we tried to live on only meat and animal fat (we need more fiber, more carbohydrates, and many micronutrients that we usually get from plants)
The closest that humans tend to come to doing such is the ketogenic diet, which focuses on a high fat, low carbohydrate imbalance, to promote ketosis, in which the body burns fat for energy.
The ketogenic diet does work, and/but can cause a lot of health problems if a lot of care is not taken to avoid them.
See for example: 7 Keto Risks To Keep In Mind
Saturated fat is terrible for the health and should be avoided: True or False?
False, if we are talking about “completely”.
Firstly, it’s practically impossible to cut out all saturated fats, given that most dietary sources of fat are a mix of saturated, unsaturated (mono- and poly-), and trans fats (which are by far the worst, but beyond the scope of today’s main feature).
Secondly, a lot of research has been conducted and found insignificant or inconclusive results, in cases where saturated fat intake was already within acceptable levels (per the recommendations we mentioned earlier), and then cut down further.
Rather than fill up the newsletter with individual studies of this kind here’s a high-quality research review, looking at 19 meta-analyses, each of those meta-analyses having looked at many studies:
Dietary saturated fat and heart disease: a narrative review
Saturated fat is good, but only some sources, and/or in moderation: True or False?
True! The moderation part is easy to guess, so let’s take a look at the “but only some sources”.
We were not able to find any convincing science to argue for health-based reasons to favor plant- or animal-sourced saturated fat. However…
Not all saturated fats are created equal (there are many kinds), and also many of the foods containing them have additional nutrients, or harmful compounds, that make a big difference to overall health, when compared gram-for-gram in terms of containing the same amount of saturated fat.
For example:
- Palm oil’s saturated fat contains a disproportionate amount of palmitic acid, which raises LDL (“bad” cholesterol) without affecting HDL (“good” cholesterol), thus having an overall heart-harmful effect.
- Most animal fats contain a disproportionate amount of stearic acid, which has statistically insignificant effects on LDL and HDL levels, and thus is broadly considered “heart neutral” (in moderation!)
- Coconut oil’s saturated fat contains a disproportionate amount of lauric acid, which raises total cholesterol, but mostly HDL without affecting LDL, thus having an overall heart-beneficial effect (in moderation!)

Brain Maker – by Dr. David Perlmutter
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.
Regular 10almonds readers probably know about the gut-brain connection already, so what’s new here?
Dr. David Perlmutter takes us on a tour of gut and brain health, specifically, the neuroprotective effect of healthy gut microbiota.
This seems unlikely! After all, vagus nerve or no, the gut microbiota are confined to the gut, and the brain is kept behind the blood-brain barrier. So how does one thing protect the other?
Dr. Perlmutter presents the relevant science, and the honest answer is, we’re not 100% sure how this happens! We do know part of it: that bad gut microbiota can result in a “leaky gut”, and that may in turn lead to such a thing as a “leaky brain”, where the blood-brain barrier has been compromised and some bad things can get in with the blood.
When it comes to gut-brain health…
Not only is the correlation very strong, but also, in tests where someone’s gut microbiota underwent a radical change, e.g. due to…
- antibiotics (bad)
- fasting (good)
- or a change in diet (either way)
…their brain health changed accordingly—something we can’t easily check outside of a lab, but was pretty clear in those tests.
We’re also treated to an exposé on the links between gut health, brain health, inflammation, and dementia… Which links are extensive.
In closing, we’ll mention that throughout this book we’re also given many tips and advices to improve our gut/brain health, reverse damage done already, and set ourselves up well for the future.

Sweet Potato vs Cassava – 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 sweet potato to cassava, we picked the sweet potato.
Why?
For any unfamiliar with cassava, it’s also called manioc or yuca/yucca, and it’s a tuber that can be used a lot like sweet potato. It’s popular in S. America, often in recipes that aren’t the healthiest (deep-fried chunky “cassava chips” are popular in Brazil, for example, and farofa, a flour made from cassava, is less healthy even than refined white flour from wheat), but today we’re going to judge it on its own merit—since after all, almost anything can be deep-fried and many things can be turned into flour, but it doesn’t mean we have to do that.
Let’s talk macros first: sweet potato has nearly 2x the protein, while cassava has nearly 2x the carbs. As for fiber to soften those carbs’ impact on our blood sugars, well, sweet potato has about 2x the fiber. All in all for macros, a clear and easy win for sweet potato.
Important note: as for the impact that has on glycemic index: the exact glycemic index will depend on what you do with it (different cooking methods change the GI), but broadly speaking, sweet potatoes are considered a medium GI food, while cassava is a very high GI food, to the point that it’s higher than sucrose, and nearly equal to pure glucose. Which is impressive, for a tuber.
In terms of vitamins, sweet potato’s famously high vitamin A content raises the bar, but it’s not all it has to offer: sweet potato has more of vitamins A, B1, B2, B3, B5, B6, E, and K, while cassava has more of vitamins B9 and choline. Just for amusement’s sake, let’s note that the sweet potato has over 1,478x the vitamin A content. In any case, the vitamins category is another clear win for sweet potato.
When it comes to minerals, it’s again quite one-sided: sweet potato has more calcium, copper, iron, magnesium, manganese, phosphorus, and potassium, while cassava has more selenium. So, sweet potato wins yet again.
In short: definitely a case of “the less widely-available option is not necessarily the healthier”!
