How special is our brain? According to Dr. Alan Jasanoff, it’s not nearly as special as we think it is.

In this work, he outlines the case for how we have collectively overstated the brain’s importance. That it’s just another organ like a heart or a kidney, and that who we are is as much a matter of other factors, as what goes on in our brain.

In this reviewer’s opinion, he overcorrects a bit. The heart and kidneys are very simple organs, as organs go. The brain is not. And while everything from our gut microbiota to our environment to our hormones may indeed contribute to what is us, our brain is one thing that can’t just be swapped out.

Nevertheless, this very well-written book can teach us a lot about everything else that makes us us, including many biological factors that many people don’t know about or consider.

Towards the end of the book, he switches into futurist speculation, and his speculation can be summed up as “we cannot achieve anything worthwhile in the future”.

Bottom line: if you’ve an interest in such things as how transplanting glial cells can give a 30% cognitive enhancement, and how a brain transplant wouldn’t result in the same us in a different body, this is the book for you.

  • Fitness Walking and Bodyweight Exercises – by Frank S. Ring

    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.

    A lot of exercise manuals assume that the reader has a “basic” body (nothing Olympian, but nothing damaged either). As we get older, increasingly few of us fall into the “but nothing damaged either” category!

    Here’s where Ring brings to bear his decades of experience as a coach and educator, and also his personal recovery from a serious back injury.

    The book covers direct, actionable exercise advice (with all manner of detail), and also offers mental health tips he’s learned along the way.

    Ring, like us, is a big fan of keeping things simple, so he focusses on “the core four” of bodyweight exercises:

    1. Pushups
    2. Squats
    3. Lunges
    4. Planks

    These four exercises get a whole chapter devoted to them, though! Because there are ways to make each exercise easier or harder, or have different benefits. For example, adjustments include:

    • Body angle
    • Points of contact
    • Speed
    • Pausing
    • Range of motion

    This, in effect, makes a few square meters of floor (and perhaps a chair or bench) your fully-equipped gym.

    As for walking? Ring enjoys and extols the health benefits, and/but also uses his walks a lot for assorted mental exercises, and recommends we try them too.

    A fine book for anyone who wants to gain and/or maintain good health, but doesn’t pressingly want to join a gym or start pumping iron!

  • Whole – by Dr. T. Colin Campbell

    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.

    Most of us have at least a broad idea of what we’re supposed to be eating, what nutrients we should be getting. Many of us look at labels, and try to get our daily dose of this and that and the other.

    And what we don’t get from food? There are supplements.

    Dr. Campbell thinks we can do better:

    Perhaps most critical in this book, where it stands out from others (we may already know, for example, that we should try to eat diverse plants and whole foods) is its treatment of why many supplements aren’t helpful.

    We tend to hear “supplements are a waste of money” and sometimes they are, sometimes they aren’t. How to know the difference?

    Key: things directly made from whole food sources will tend to be better. Seems reasonable, but… why? The answer lies in what else those foods contain. An apple may contain a small amount of vitamin C, less than a vitamin C tablet, but also contains a whole host of other things—tiny phytonutrients, whose machinations are mostly still mysteries to us—that go with that vitamin C and help it work much better. Lab-made supplements won’t have those.

    There’s a lot more to the book… A chunk of which is a damning critique of the US healthcare system (the author argues it would be better named a sicknesscare system). We also learn about getting a good balance of macro- and micronutrients from our diet rather than having to supplement so much.

    The style is conversational, while not skimping on the science. The author has had more than 150 papers published in peer-reviewed journals, and is no stranger to the relevant academia. Here, however, he focuses on making things easily comprehensible to the lay reader.

    In short: if you’ve ever wondered how you’re doing at getting a good nutritional profile, and how you could do better, this is definitely the book for you.

  • Intermittent Fasting, Intermittently?

    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? 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 😎

    ❝Have you come across any research on alternate-day intermittent fasting—specifically switching between one day of 16:8 fasting and the next day of regular eating patterns? I’m curious if there are any benefits or drawbacks to this alternating approach, or if the benefits mainly come from consistent intermittent fasting?❞

    Short and unhelpful answer: no

    Longer and hopefully more helpful answer:

    As you probably know, usually people going for approaches based on the above terms either

    • practise 16:8 fasting (fast for 16 hours each day, eat during an 8-hour window) or
    • practise alternate-day fasting (fast for 24 hours, eat whenever for 24 hours, repeat)

    …which latter scored the best results in this large meta-analysis of studies:

    Effects of different types of intermittent fasting on metabolic outcomes: an umbrella review and network meta-analysis

    There is also the (popular) less extreme version of alternate-day fasting, sometimes called “eat stop eat”, which is not a very helpful description because that describes almost any kind of eating/fasting, but it usually refers to “once per week, take a day off from eating”.

    You can read more about each of these (and some other variants), here:

    Intermittent Fasting: What’s The Truth?

    What you are describing (doing 16:8 fasting on alternate days, eating whenever on the other days) is essentially: intermittent fasting, just with one 16-hour fast per 48 hours instead of per the usual 24 hours.

    See also: International consensus on fasting terminology ← the section on the terms “STF & PF” covers why this gets nudged back under the regular IF umbrella

    Good news: this means there is a lot of literature into the acute (i.e., occurring the same day, not long-term)* benefits of 16:8 IF, and that means that you will be getting those benefits, every second day.

    You remember that meta-analysis we posted above? While it isn’t mentioned in the conclusion (which only praised complete alternate-day fasting producing the best outcomes overall), sifting through the results data discovers that time-restricted eating (which is what you are doing, by these classifications) was the only fasting method to significantly reduce fasting blood glucose levels.

    (However, no significant differences were observed between any IF form and the reference (continuous energy restriction, CER, i.e. calorie-controlled) diets in fasting insulin and HbA1c levels)

    *This is still good news in the long-term though, because getting those benefits every second day is better than getting those benefits on no days, and this will have a long-term impact on your healthy longevity, just like how it is better to exercise every second day than it is to exercise no days, or better to abstain from alcohol every second day than it is to abstain on no days, etc.

    In short, by doing IF every second day, you are still giving your organs a break sometimes, and that’s good.

    All the same, if it would be convenient and practical for you, we would encourage you to consider either the complete alternate-day fasting (which, according to a lot of data, gives the best results overall),or time-restricted eating (TRE) every day (which, according to a lot of data, gives the best fasting blood sugar levels).

    You could also improve the TRE days by shifting to 20:4 (i.e., 20 hours fasting and 4 hours eating), this giving your organs a longer break on those days.

  • The Lies That Depression Tells Us

    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.

    In this short (6:42) video, psychiatrist Dr. Tracey Marks talks about 8 commonly-believed lies that depression often tells us. They are:

    • “I don’t measure up”
    • “No one cares about me”
    • “I’m better off alone”
    • “No one understands”
    • “It’s all my fault”
    • “I have no reason to be depressed”
    • “Nothing matters”
    • “I’ll never get better”

    Some of these can be reinforced by people around us; it’s easy to believe that “no one understands” if for example the few people we interact with the most don’t understand, or that “I have no reason to be depressed” if people try to cheer you up by pointing out your many good fortunes.

    The reality, of course, is that depression is a large, complex, and many-headed beast, with firm roots in neurobiology.

    There are things we can do that may ameliorate it… But they also may not, and sometimes life is just going to suck for a while. That doesn’t mean we should give up (that, too, is depression lying to us, per “I’ll never get better”), but it does mean that we should not be so hard on ourselves for not having “walked it off” the way one might “just walk off” a broken leg.

    Oh, you can’t “just walk off” a broken leg? Well then, perhaps it’s not surprising if we don’t “just think off” a broken brain, either. The brain can rebuild itself, but that’s a slow process, so buckle in:

  • More Salt, Not Less?

    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? 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!

    So, no question/request too big or small

    ❝I’m curious about the salt part – learning about LMNT and what they say about us needing more salt than what’s recommended by the government, would you mind looking into that? From a personal experience, I definitely noticed a massive positive difference during my 3-5 day water fasts when I added salt to my water compared to when I just drank water. So I’m curious what the actual range for salt intake is that we should be aiming for.❞

    That’s a fascinating question, and we’ll have to tackle it in several parts:

    When fasting

    3–5 days is a long time to take only water; we’re sure you know most people fast from food for much less time than that. Nevertheless, when fasting, the body needs more water than usual—because of the increase in metabolism due to freeing up bodily resources for cellular maintenance. Water is necessary when replacing cells (most of which are mostly water, by mass), and for ferrying nutrients around the body—as well as escorting unwanted substances out of the body.

    Normally, the body’s natural osmoregulatory process handles this, balancing water with salts of various kinds, to maintain homeostasis.

    However, it can only do that if it has the requisite parts (e.g. water and salts), and if you’re fasting from food, you’re not replenishing lost salts unless you supplement.

    Normally, monitoring our salt intake can be a bit of a guessing game, but when fasting for an entire day, it’s clear how much salt we consumed in our food that day: zero

    So, taking the recommended amount of sodium, which varies but is usually in the 1200–1500mg range (low end if over aged 70+; high end if aged under 50), becomes sensible.

    More detail: How Much Sodium You Need Per Day

    See also, on a related note:

    When To Take Electrolytes (And When We Shouldn’t!)

    When not fasting

    Our readers here are probably not “the average person” (since we have a very health-conscious subscriber-base), but the average person in N. America consumes about 9g of salt per day, which is several multiples of the maximum recommended safe amount.

    The WHO recommends no more than 5g per day, and the AHA recommends no more than 2.3g per day, and that we should aim for 1.5g per day (this is, you’ll note, consistent with the previous “1200–1500mg range”).

    Questionable claims

    We can’t speak for LMNT (and indeed, had to look them up to discover they are an electrolytes supplement brand), but we can say that sometimes there are articles about such things as “The doctor who says we should eat more salt, not less”, and that’s usually about Dr. James DiNicolantonio, a doctor of pharmacy, who wrote a book that, because of this question today, we’ve now also reviewed:

    The Salt Fix: Why the Experts Got It All Wrong—and How Eating More Might Save Your Life – by Dr. James DiNicolantonio

    Spoiler, our review was not favorable.

    The body knows

    Our kidneys (unless they are diseased or missing) do a full-time job of getting rid of excess things from our blood, and dumping them into one’s urine.

    That includes excess sugar (which is how diabetes was originally diagnosed) and excess salt. In both cases, they can only process so much, but they do their best.

    Dr. DiNicolantino recognizes this in his book, but chalks it up to “if we do take too much salt, we’ll just pass it in urine, so no big deal”.

    Unfortunately, this assumes that our kidneys have infinite operating capacity, and they’re good, but they’re not that good. They can only filter so much per hour (it’s about 1 liter of fluids). Remember we have about 5 liters of blood, consume 2–3 liters of water per day, and depending on our diet, several more liters of water in food (easy to consume several more liters of water in food if one eats fruit, let alone soups and stews etc), and when things arrive in our body, the body gets to work on them right away, because it doesn’t know how much time it’s going to have to get it done, before the next intake comes.

    It is reasonable to believe that if we needed 8–10g of salt per day, as Dr. DiNicolantonio claims, our kidneys would not start dumping once we hit much, much lower levels in our blood (lower even than the daily recommended intake, because not all of the salt in our body is in our blood, obviously).

    Lastly, a note about high blood pressure

    This is one where the “salt’s not the bad guy” crowd have at least something close to a point, because while salt is indeed still a bad guy (if taken above the recommended amounts, without good medical reason), when it comes to high blood pressure specifically, it’s not the worst bad guy, nor is it even in the top 5:

  • Kiwi Fruit vs Pineapple – 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 kiwi fruit to pineapple, we picked the kiwi.

    Why?

    In terms of macros, they’re mostly quite comparable, being fruits made of mostly water, and a similar carb count (slightly different proportions of sugar types, but nothing that throws out the end result, and the GI is low for both). Technically kiwi has twice the protein, but they are fruits and “twice the protein” means “0.5g difference per 100g”. Aside from that, and more meaningfully, kiwi also has twice the fiber.

    When it comes to vitamins, kiwi has more of vitamins A, B9, C, E, K, and choline, while pineapple has more of vitamins B1, B2, B3, B5, and B6. This would be a marginal (6:5) win for kiwi, but kiwi’s margins of difference are greater per vitamin, including 72x more vitamin E (with a cupful giving 29% of the RDA, vs a cupful of pineapple giving 0.4% of the RDA) and 57x more vitamin K (with a cupful giving a day’s RDA, vs a cupful of pineapple giving a little under 2% of the RDA). So, this is a fair win for kiwi.

    In the category of minerals, things are clear: kiwi has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while pineapple has more manganese. An overwhelming win for kiwi.

    Looking at their respective anti-inflammatory powers, pineapple has its special bromelain enzymes, which is a point in its favour, but when it comes to actual polyphenols, the two fruits are quite balanced, with kiwi’s flavonoids vs pineapple’s lignans.

    Adding up the sections, it’s a clear win for kiwi—but pineapple is a very respectable fruit too (especially because of its bromelain content), so do enjoy both!
