How To Clean Your Brain (Glymphatic Health Primer)

That’s not a typo! The name “glymphatic system” was coined by the Danish neuroscientist Dr. Maiken Nedergaard, and is a nod to its use of glial cells to do a similar job to that of the peripheral lymphatic system—but this time, in the CNS. Today, we have Dr. Jin Sung to tell us more:

Brainwashing (but not like that)

The glymphatic system may sound like a boring job, but so does “sanitation worker” in a city—yet the city would grind to a messy halt very very quickly without them. Same goes for your brain.

Diseases that are prevalent when this doesn’t happen the way it should include Alzheimer’s (beta-amyloid clearance) and Parkinson’s (alpha-synuclein clearance) amongst others.

Things Dr. Sung recommends for optimal glymphatic function include: sleep (7–9 hours), exercise (30–45 minutes daily), hydration (half your bodyweight in pounds, in ounces, so if your body weighs 150 lbs, that means 75 oz of water), good posture (including the use of good ergonomics, e.g. computer monitor at right height, car seat correct, etc), stress reduction (reduces inflammatory cytokines), getting enough omega-3 (the brain needs certain fats to work properly, and this is the one most likely to see a deficit), vagal stimulation (methods include humming, gargling, and gagging—please note we said vagal stimulation; easy to misread at a glance!), LED light therapy, and fasting (intermittent or prolonged).

  • The Plant-Based Diet Revolution – by Dr. Alan Desomond

    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.

    Is this just another gut-healthy cooking guide? Not entirely…

    For a start, it’s not just about giving you a healthy gut; it also covers a healthy heart and a healthy brain. There’s lots of science in here!

    It’s also aimed as a transitional guide to eating more plants and fewer animal products, if you so choose. And if you don’t so choose, at least having the flexibility to cook both ways.

    The recipes themselves (organized into basics, breakfasts, lunches, mains, desserts) are clear and easy while also being calculated to please readers (and their families) who are used to eating more meat. There are, for instance, plenty of healthy proteins, healthy fats, and comfort foods.

    The “28 days” of the title refers to a meal plan using the recipes from the book; it’s not a big feature of the book though, so use it or don’t, but the cooking advice itself is more than worth the price of the book and the recipes are certainly great.

    Bottom line: if you’re thinking of taking a “Meatless Mondays” approach to making your diet healthier, this book can help you do that in style!

  • Why We’re Called “10almonds”, And Other Questions

    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.

    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

    ❝Avid coffee drinker so very interested in the results Also question Is there something that you could take or eat that would prevent the caffeine from stimulating the kidneys? I tried to drink decaf from morning to night not a good result! Thanks❞

    That is a good question! The simple answer is “no” (but keep reading, because all is not lost)

    There’s no way (that we yet know of) to proof the kidneys against the stimulating effect of caffeine. This is especially relevant because part of caffeine’s stimulating effect is noradrenergic, and that “ren” in the middle there? It’s about the kidneys. This is just because the adrenal gland is situated next to them (actually, it’s pretty much sitting on top of them), hence the name, but it does mean that the kidneys are about the hardest thing in the body to have not affected by caffeine.

    However! The effects of caffeine in general can be softened a little with l-theanine (found in tea, or it can be taken as a supplement). It doesn’t stop it from working, but it makes the curve of the effect a little gentler, and so it can reduce some unwanted side effects.

    You can read more about l-theanine here:

    L-Theanine: What’s The Tea?

    ❝How to jump start a inactive metabolism and keep it going? THANKYOU❞

    The good news is, if you’re alive, your metabolism is active (it never stops!). So, it may just need perking up a little.

    As for keeping it going, well, that’s what we’re here for! We’re all in favor of healthy longevity.

    We’ll do a main feature soon on what we can do to influence our metabolism in either direction, but to give some quick notes here:

    • A lot of our metabolism is influenced by genes and is unalterable (without modifying our genes, anyway)
    • Metabolism isn’t just one thing—it’s many. And sometimes, parts of our metabolism can be much quicker or slower than others.
    • When people talk about wanting a “faster metabolism”, they’re usually referring to fat-burning, and that’s just a small part of the picture, but we understand that it’s a focal point for many.

    There really is enough material for a whole main feature on metabolic tweaks, though, so watch this space!

    ❝Why the name “10 Almonds?” Is this recommended by the Doctor? A daily dosage? And, if so, why? Thanks! Please answer me…I truly want to know!❞

    Almonds are very nutritionally dense, and for example 20g of almonds (so, about 20 almonds) would give a 100% daily dose of zinc, amongst other nutrients.

    We also do like to think that we give our readers an easily digestible dose of condensed “nutrition” in the form of health information.

    However! That’s not actually the reason at all. It’s a reference to a viral Facebook hoax! There was a post going around that claimed:

    ❝HEADACHE REMEDY. Eat 10–12 almonds, the equivalent of two aspirins, next time you have a headache❞ ← not true!

    It made us think about how much health-related disinformation there was circulating online! So, calling ourselves 10almonds was a bit of a nod to that story, but also a reminder to ourselves:

    We must always publish information with good scientific evidence behind it!

  • When the Body Says No – by Dr. Gabor Maté

    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 know that chronic stress is bad for us because of what it does to our cortisol levels, so what is the rest of this book about?

    Dr. Gabor Maté is a medical doctor, heavily specialized in the impact of psychological trauma on long term physical health.

    Here, he examies—as the subtitle promises—the connection between stress and disease. As it turns out, it’s not that simple.

    We learn not just about the impact that stress has on our immune system (including increasing the risk of autoimmune disorders like rheumatoid arthritis), the cardiovascular system, and various other critical systems fo the body… But also:

    • how environmental factors and destructive coping styles contribute to the onset of disease, and
    • how traumatic events can warp people’s physical perception of pain
    • how certain illnesses are associated with particular personality types.

    This latter is not “astrology for doctors”, by the way. It has more to do with what coping strategies people are likely to employ, and thus what diseases become more likely to take hold.

    The book has practical advice too, and it’s not just “reduce your stress”. Ideally, of course, indeed reduce your stress. But that’s a) obvious b) not always possible. Rather, Dr. Maté explains which coping strategies result in the least prevalence of disease.

    In terms of writing style, the book is very much easy-reading, but be warned that (ironically) this isn’t exactly a feel-good book. There are lot of tragic stories in it. But, even those are very much well-worth reading.

    Bottom line: if you (and/or a loved one) are suffering from stress, this book will give you the knowledge and understanding to minimize the harm that it will otherwise do.

  • You Are Not a Before Picture – by Alex Light

    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.

    It’s that time of year, and many of us are looking at what we’ll do in the coming days, weeks, and months to level-up our health. So… Is this a demotivational book?

    Quite the opposite! It’s rather a case of an often much-needed reminder to ensure that our plans are really our own, and really are what’s best for us. Why wouldn’t they be, you ask?

    Much of diet culture (ubiquitous! From magazine covers to movie stars to the models advertising anything from health insurance to water filters) has us reaching for “body goals” that are not possible without a different skeleton and genes and compromises and post-production edits.

    Alex Light—herself having moved from the fashion and beauty industry into health education—sets out in a clear, easy-reading manner, how we can look after ourselves, not be neglectful of our bodies, and/but also not get distracted into unhelpful, impossible, castles-in-the-air.

    Bottom line: you cannot self-hate your way into good health, and good health will always be much more attainable than a body that’s just not yours. This book can help you sort out which is which.

    Click here to check out You Are Not A Before Picture, and appreciate all you and your body can (and do) do for each other!

  • How To Reduce Or Quit Alcohol

    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.

    Rethinking Drinking

    When we’re looking at certain health risks, there are often five key lifestyle factors that have a big impact; they are:

    • Have a good diet
    • Get good exercise
    • Get good sleep
    • Reduce (or eliminate) alcohol
    • Don’t smoke

    Today, we’re focussing the alcohol bit. Maybe you’d like to quit, maybe just cut down, maybe the topic just interests you… So, here’s a quick rundown of some things that will help make that a lot easier:

    With a big enough “why”, you can overcome any “how”

    Research and understand the harm done by drinking, including:

    And especially as we get older, memory problems:

    Alcohol-related dementia: an update of the evidence

    And as for fear of missing out, or perhaps even of no longer being relaxed/fun… Did you ever, while sober, have a very drunk person try to converse with you, and you thought “I wish that were me”?

    Probably not

    Know your triggers

    Why do you drink? If your knee-jerk response is “because I like it”, dig deeper. What events prompt you to have a drink?

    • Some will be pure habit born of convention—perhaps with a meal, for example
    • Others may be stress-management—after work, perhaps
    • Others may be pseudo-medicinal—a nightcap for better* sleep, for instance

    *this will not work. Alcohol may make us sleepy but it will then proceed to disrupt that very sleep and make it less restorative

    Become mindful

    Now that you know why you’d like to drink less (or quit entirely), and you know what triggers you to drink, you can circumvent that a little, by making deals with yourself, for example

    • “I can drink alcohol, if and only if I have consumed a large glass of water first” (cuts out being thirsty as a trigger to drink)
    • “I can drink alcohol, if and only if I meditate for at least 5 minutes first” (reduces likelihood of stress-drinking)
    • “I can drink alcohol, if and only if it is with the largest meal of the day” (minimizes total alcohol consumption)

    Note that these things also work around any FOMO, “Fear Of Missing Out”. It’s easier to say “no” when you know you can have it later if you still want it.

    Get a good replacement drink

    There are a lot of alcohol-free alcohol-like drinks around these days, and many of them are very good. Experiment and see. But!

    It doesn’t even have to be that. Sometimes what we need is not even an alcohol-like drink, but rather, drinkable culinary entertainment.

    If you like “punch-in-the-face” flavors (as this writer does), maybe strong black coffee is the answer. If you like “crisp and clear refreshment” (again, same), maybe your favorite herbal tea will do it for you. Or maybe for you it’ll be lemon-water. Or homemade ginger ale.

    Whatever it is… make it fun, and make it yours!

    Bonus item: find replacement coping strategies

    This one goes if you’ve been using alcohol to cope with something. Stress, depression, anxiety, whatever it may be for you.

    The thing is, it feels like it helps briefly in the moment, but it makes each of those things progressively worse in the long-run, so it’s not sustainable.

    Consider instead things like therapy, exercise, and/or a new hobby to get immersed in; whatever works for you!

  • Natto vs Tofu – 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 nattō to tofu, we picked the nattō.

    Why?

    In other words, in the comparison of fermented soy to fermented soy, we picked the fermented soy. But the relevant difference here is that nattō is fermented whole soybeans, while tofu is fermented soy milk of which the coagulated curds are then compressed into a block—meaning that the nattō is the one that has “more food per food”.

    Looking at the macros, it’s therefore no surprise that nattō has a lot more fiber to go with its higher carb count; it also has slightly more protein. You may be wondering what tofu has more of, and the answer is: water.

    In terms of vitamins, nattō has more of vitamins B2, B4, B6, C, E, K, and choline, while tofu has more of vitamins A, B3, and B9. So, a 7:3 win for nattō, even before considering that that vitamin C content of nattō is 65x more than what tofu has.

    When it comes to minerals, nattō has more copper, iron, magnesium, manganese, potassium, and zinc, while tofu has more calcium, phosphorus, and selenium. So, a 6:3 win for nattō, and yes, the margins of difference are comparable (being 2–3x more for most of these minerals).

    In short, both of these foods are great, but nattō is better.
