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.

  • How To April Fool Yourself Into Having A Nutrient-Dense Diet!

    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.

    These nutrient-dense foods pack such a punch you only need a bit added to your meal…

    • “Have 5 servings of fruit per day”—popular wisdom in the West
    • “Have 7 servings of fruit per day!”—generally held as the norm in Japan
    • “Have these 12 things that are mostly fruit & veg & nuts each day”Dr. Greger’s Daily Dozen
    • “Does the pickle that comes with a burger count?”—an indication of how much many people struggle.

    For what it’s worth: pickles are a good source of some minerals (and some healthy gut bacteria too), but are generally too high in sodium to be healthy for most people beyond in the most modest moderation.

    But! It can be a lot easier, and without sitting down to a salad buffet every day!

    Here are some sneaky tips:

    (call it our nod to April Fool’s Day, because tricking yourself into eating more healthily is a top-tier prank)

    Beyond soups and smoothies

    Soups and smoothies are great, because we can take a lot of nutrients that way without actually oing much eating. And if we’ve a want or need to hide something, blending it does a fine job. However, we’re confident you already know how to make soups and smoothies. So…

    Sauces are another excellent place to put nutrients—and as a bonus, homemade sauces will mean skipping on the store-bought sauces whose ingredients all-too-often look something like “sugar, water, spirit vinegar, glucose-fructose syrup, modified maize starch, maltodextrin, salt…”

    Top things to use as a main base ingredient in sauces:

    • Tomato purée—so much lycopene, and great vitamins too! Modest flavour, but obviously only sensible for what you intend to be a tomato-based sauce. Use it to make anything from marinara sauce to ketchup, sweet-and-sour to smoky barbecue.
    • Lentils/beans—if unsure, red lentils or haricot beans have a very mild taste, and edamame beans are almost not-there, flavor-wise. But cooked and blended smooth, these are high-protein, iron-rich, flavonoid-heavy, and a good source of fiber too. Can be used as the base of so many savory creamy sauces!
    • Corn—that yellow color? It’s all the lutein. Home-made creamed corn goes great as a dipping sauce! Added spices optional.

    Vegetables that punch above their weight

    Sometimes, you might not want to eat much veg, but a small edible side-dish could be appealing, or even a generous garnish. In those cases, if you choose wisely, you can have a lot of nutrients in a tiny portion. Here are some that have an absurd nutrient-to-size ratio:

    Cacao nibs—one for the dessert-lovers here, but can also garnish a frothy coffee, your morning overnight oats, or if we’re honest, can also just be snacked on! And they keep for ages. Botanically technically a fruit, but we’re going to throw it in here. As for health qualities? Where to begin…

    They:

    …which is starting to look like a pattern, isn’t it? It’s good against cancer.

    Brussels sprouts—if your knee-jerk reaction here wasn’t one of great appeal, then consider: these are delicious if done right.

    Buy them fresh, not frozen (nothing nutritionally wrong with frozen if you like them—we’re just doing the extra-level tastiness here). Wash them and peel them, then cut twice from the top to almost-the-bottom, to quarter them in a way that they still stay in one piece. Rub them (or if you’re going easier on the fats, spray them) with a little olive oil, a tiny touch of lemon juice, and sprinkle a little cracked black pepper. Sautée them. We know people will advise roasting, which is also great, but try the sautée approach, and thank us later.

    Four sprouts is already a sufficient daily serving of cruciferous vegetables, and provides so many health benefits, with not just a stack of vitamins and minerals, but also have anti-cancer properties, are great for your heart in multiple ways, and reduce inflammation too. They’re literally one of the healthiest foods out there and you only need a tiny portion to benefit.

    Kale—Don’t like the taste/texture? That’s OK, read on… No surprises here, but it’s crammed with vitamins and minerals.

    • If you don’t care for the bitter taste, cooking it (such as by steaming it) takes that away.
    • If you don’t care for the texture, baking it with a little sprayed-on olive oil changes that completely (and is how “kale chips” are made).
    • If you don’t care for either? Do the “kale chips” thing mentioned above, but do it on a lower heat for longer—dry it out, basically. Then either blend it in a food processor, or by hand with a pestle and mortar (it turns to powder very easily, so this won’t be hard work), and you now have a very nutrient-dense powder that tastes of very little. While fries are not a health food, an example here is that you can literally dust fries with it and they won’t taste any different but you got a bunch of vitamins and minerals added from a whole food source.
      • If going for the above approach, do it in batch and make yourself a jar of it to keep handy with your seasonings collection!

    Bell peppers—Working hard to justify their high prices in the grocery store, these are very high in vitamins, especially rich in carotenoids, including lutein, and as a bonus, they’re also full of antioxidants. So, slice some and throw them at whatever else you’re cooking, and you’ve added a lot of nutrients for negligible effort.

    Garlic—once you’ve done the paperwork, garlic not only makes bland meals delicious, but is also a treasure trove of micronutrients. It has a stack of vitamins and minerals, and also contains allicin. If you’ve not heard of that one, it’s the compound in garlic that is so good for blood pressure and heart health. See for example:

    If an apple a day keeps the doctor away, just imagine what a bulb of garlic can do (come on, we can’t be the only ones who measure garlic by the bulb instead of by the clove, right?)!

    But in seriousness: measure garlic with your heart—have lots or a little, per your preference. The whole point here is that even a little of these superfoods can make a huge difference to your health!

  • Science of Pilates – by Tracy Ward

    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’ve reviewed other books in this series, “Science of Yoga” and “Science of HIIT” (they’re great too; check them out!). What does this one add to the mix?

    Pilates is a top-tier “combination exercise” insofar as it checks a lot of boxes, e.g:

    • Strength—especially core strength, but also limbs
    • Mobility—range of motion and resultant reduction in injury risk
    • Stability—impossible without the above two things, but Pilates trains this too
    • Fitness—many dynamic Pilates exercises can be performed as cardio and/or HIIT.

    The author, a physiotherapist, explains (as the title promises!) the science of Pilates, with:

    • the beautifully clear diagrams we’ve come to expect of this series,
    • equally clear explanations, with a great balance of simplicity of terms and depth where necessary, and
    • plenty of citations for the claims made, linking to lots of the best up-to-date science.

    Bottom line: if you are in a position to make a little time for Pilates (if you don’t already), then there is nobody who would not benefit from reading this book.

  • Your Brain on Art – by Susan Magsamen & Ivy Ross

    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.

    The notion of art therapy is popularly considered a little wishy-washy. As it turns out, however, there are thousands of studies showing its effectiveness.

    Nor is this just a matter of self-expression. As authors Magsamen and Ross explore, different kinds of engagement with art can convey different benefits.

    That’s one of the greatest strengths of this book: “this form of engagement with art will give these benefits, according to these studies”

    With benefits ranging from reducing stress and anxiety, to overcoming psychological trauma or physical pain, there’s a lot to be said for art!

    And because the book covers many kinds of art, if you can’t imagine yourself taking paintbrush to canvas, that’s fine too. We learn of the very specific cognitive benefits of coloring in mandalas (yes, really), of sculpting something terrible in clay, or even just of repainting the kitchen, and more. Each thing has its set of benefits.

    The book’s main goal is to encourage the reader to cultivate what the authors call an aesthetic mindset, which involves four key attributes:

    • a high level of curiosity
    • a love of playful, open-ended exploration
    • a keen sensory awareness
    • a drive to engage in creative activities

    And, that latter? It’s as a maker and/or a beholder. We learn about what we can gain just by engaging with art that someone else made, too.

    Bottom line: come for the evidence-based cognitive benefits; stay for the childlike wonder of the universe. If you already love art, or have thought it’s just “not for you”, then this book is for you.

  • Passion Fruit vs Pomegranate – 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 passion fruit to pomegranate, we picked the passion fruit.

    Why?

    Both of these fruits have beaten a lot of other contenders, so it’s time to pit them against each other:

    In terms of macros, passion fruit has more protein, carbs, and fiber, the ratio of which meaning also that passion fruit has the lower glycemic index. So, we say passion fruit wins on macros.

    In the category of vitamins, things are more even; passion fruit has more of vitamins A, B2, B3, B6, and C, while pomegranate has more of vitamins B1, B5, B9, E, and K. In light of this 5:5 tie, and since passion fruit’s overall vitamin coverage is better (in terms of meeting RDA needs) but pomegranate’s vitamins are often in shorter supply in diet, we’re calling it a tie on vitamins.

    When it comes to minerals, passion fruit has more calcium, iron, magnesium, phosphorus, potassium, and selenium, while pomegranate has more copper, manganese, and zinc. That’s already an easy 6:3 win for passion fruit, before we even consider the fact that passion fruit’s minerals’ margin of difference is greater too.

    Adding it up makes for a clear win for passion fruit. As ever when it comes to plants, enjoy both if you can, though!

  • Pistachios vs Peanuts – 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 pistachios to peanuts, we picked the peanuts.

    Why?

    The choice might be surprising; after all, peanuts are usually the cheapest and most readily available nuts, popularly associated with calories and not much else. However! This one was super-close, and peanuts won very marginally, as you’ll see.

    In terms of macros, pistachios have slightly more fiber and nearly 2x the carbs, while peanuts have slightly more protein and fats. What we all as individuals might prioritize more there is subjective, but this could arguably be considered a tie. About the fiber and carbs: peanuts have the lower glycemic index, but not by much. And about those fats: yes, they are healthy, and the fat breakdown for each is almost identical: pistachios have 53% monounsaturated, 33% polyunsaturated, and 14% saturated, while peanuts have 53% monounsaturated, 34% polyunsaturated, and 14% saturated. Yes, that adds up to 101% in the case of peanuts, but that’s what happens with rounding things to integers. However, the point is clear: both of these nuts have almost identical fats.

    In the category of vitamins, pistachios have more of vitamins A, B1, B2, B6, and C, while peanuts have more of vitamins B3, B5, B9, E, and choline, So, a 5:5 tie on vitamins.

    When it comes to minerals, pistachios have more calcium, copper, phosphorus, and potassium, while peanuts have more iron, magnesium, manganese, selenium, and zinc. So, a marginal victory for peanuts (and yes, the margins of difference were similar in each case).

    Adding up the tie, the other tie, and the marginal victory for peanuts, means a marginal victory for peanuts in total.

    A quick note in closing though: this was comparing raw unsalted nuts in both cases, so do take that into account when buying nuts, and at the very least, skip the salted, unless you are deficient in sodium. Or if you’re using them for cooking, then buying salted nuts because they’re usually cheaper is fine; just soak and rinse them to remove the salt.

  • The “Five Tibetan Rites” & Why To Do Them!

    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.

    Spinning Around

    In Tuesday’s newsletter, we asked you for your opinion of the “Five Tibetan Rites”, and got the above-depicted, below-described, set of responses:

    • About 41% said “I have never heard of these before”
    • About 27% said “they restore youth by adjusting internal vortexes”
    • About 22% said “they are basically yoga, by a different name”
    • About 11% said “they are a pseudoscience popular in the US”

    So what does the science say?

    The Five Tibetan Rites are five Tibetan rites: True or False?

    False, though this is more question of social science than of health science, so we’ll not count it against them for having a misleading name.

    The first known mentioning of the “Five Tibetan Rites” is by an American named Peter Kelder, who in 1939 published, through a small LA occult-specialized publishing house, a booklet called “The Eye of Revelation”. This work was then varyingly republished, repackaged, and occasionally expanded upon by Kelder or other American authors, including Chris Kilham’s popular 1994 book “The Five Tibetans”.

    The “Five Tibetan Rites” are unknown as such in Tibet, except for what awareness of them has been raised by people asking about them in the context of the American phenomenon.

    Here’s a good history book, for those interested:

    The Secret of the Five Rites: In Search of a Lost Western Tradition of Inner Alchemy – by John Michael Greer

    The author didn’t originally set out to “debunk” anything, and is himself a keen spiritualist (and practitioner of the five rites), but he was curious about the origins of the rites, and ultimately found them—as a collection of five rites, and the other assorted advices given by Kelder—to be an American synthesis in the whole, each part inspired by various different physical practices (some of them hatha yoga, some from the then-popular German gymnastics movement, some purely American spiritualism, all available in books that were popular in California in the early 1900s).

    You may be wondering: why didn’t Kelder just say that, then, instead of telling stories of an ancient Tibetan tradition that empirically does not exist? The answer to this lies again in social science not health science, but it’s been argued that it’s common for Westerners to “pick ‘n’ mix” ideas from the East, champion them as inscrutably mystical, and (since they are inscrutable) then simply decide how to interpret and represent them. Here’s an excellent book on this, if you’re interested:

    Orientalism – by Edward Said

    (in Kelder’s case, this meant that “there’s a Tibetan tradition, trust me” was thus more marketable in the West than “I read these books in LA”)

    They are at least five rites: True or False?

    True! If we use the broad definition of “rite” as “something done repeatedly in a solemn fashion”. And there are indeed five of them:

    1. Spinning around (good for balance)
    2. Leg raises (this one’s from German gymnastics)
    3. Kneeling back bend (various possible sources)
    4. Tabletop (hatha yoga, amongst others)
    5. Pendulum (hatha yoga, amongst others) ← you may recognize this one from the Sun Salutation

    You can see them demonstrated here:

    Kelder also advocated for what was basically the Hay Diet (named not for the substance but for William Hay; it involved separating foods into acid and alkali, not necessarily according to the actual pH of the foods, and combining only “acid” foods or only “alkali” foods at a time), which was popular at the time, but has since been rejected as without scientific merit. Kelder referred to this as “the sixth rite”.

    The Five Rites restore youth by adjusting internal vortexes: True or False?

    False, in any scientific sense of that statement. Scientifically speaking, the body does not have vortexes to adjust, therefore that is not the mechanism of action.

    Spiritually speaking, who knows? Not us, a humble health science publication.

    The Five Rites are a pseudoscience popular in the US: True or False?

    True, if 27% of those who responded of our mostly North American readership can be considered as representative of what is popular.

    However…

    “Pseudoscience” gets thrown around a lot as a bad word; it’s often used as a criticism, but it doesn’t have to be. Consider:

    A small child who hears about “eating the rainbow” and mistakenly understands that we are all fuelled by internal rainbows that need powering-up by eating fruits and vegetables of different colors, and then does so…

    …does not hold a remotely scientific view of how things are happening, but is nevertheless doing the correct thing as recommended by our best current science.

    It’s thus a little similar with the five rites. Because…

    The Five Rites are at least good for our health: True or False?

    True! They are great for the health.

    The first one (spinning around) is good for balance. Science would recommend doing it both ways rather than just one way, but one is not bad. It trains balance, trains our stabilizing muscles, and confuses our heart a bit (in a good way).

    See also: Fall Special (How To Not Fall, And Not Get Injured If You Do)

    The second one (leg raises) is excellent for core strength, which in turn helps keep our organs where they are supposed to be (this is a bigger health issue than most people realise, because “out of sight, out of mind”), which is beneficial for many aspects of our health!

    See also: Visceral Belly Fat & How To Lose Itvisceral fat is the fat that surrounds your internal organs; too much there becomes a problem!

    The third, fourth, and fifth ones stretch our spine (healthily), strengthen our back, and in the cases of the fourth and fifth ones, are good full-body exercises for building strength, and maintaining muscle mass and mobility.

    See also: Building & Maintaining Mobility

    So in short…

    If you’ve been enjoying the Five Rites, by all means keep on doing them; they might not be Tibetan (or an ancient practice, as presented), and any mystical aspect is beyond the scope of our health science publication, but they are great for the health in science-based ways!

    Take care!
