Eat beans & greens, take walks, have a purpose; you can probably list off the top of your head some of the “advices from Blue Zones”, so what makes this book stand out?

This is perhaps one of the most thoughtful investigations; the author (a National Geographic researcher) toured and researched all the Blue Zones, took many many notes (we get details), and asked a lot of questions that others skipped.

For example, a lot of books about the Blue Zones mention the importance of community—but they don’t go into much detail of what that looks like… And they certainly don’t tend to explain what we should do about it.

And that’s because community is often viewed as environmental in a way that we can’t control. If we want to take supplements, eat a certain way, exercise, etc, we can do all those things alone if we want. But if we want community? We’re reliant on other people—and that’s a taboo in the US, and US-influenced places.

So, one way this book excels is in describing how exactly people foster community in the Blue Zones (hint: the big picture—the form of the community—is different in each place, but the individual actions taken are similar), with particular attention to the roles actively taken on by the community elders.

In a similar vein, “reduce stress” is good, but what mindsets and mechanisms do they use that are still reproducible if we are not, for example, Okinawan farmers? Again, Buettner delivers in spades.

Bottom line: this is the Blue Zones book that digs deeper than others, and makes the advices much more applicable no matter where we live.

    Can you keep a secret?

    When actor Christopher Lee was asked about his time as a British special forces operative, he would look furtively around, and ask “can you keep a secret?” Upon getting a yes, he would reply:

    “So can I”

    We can’t, though! We just can’t help sharing cool, useful information that changes people’s lives. Never is that more critical than now, as the end of January has been called the most depressing time of year, according to Dr. Cliff Arnall at the University of Cardiff. It doesn’t have to be all doom and gloom, though:

    Today we’re going to share a trick… It’s called the “secret of eternal happiness” (yes, we know… we didn’t come up with the name!) and is taught to soldiers to fend off the worst kinds of despair.

    The soldiers would be ordered to take a moment to reflect on the sheer helplessness of their situation, the ridiculous impossibility of the odds against them, all and any physical pain they might suffer, the weakness of their faltering body… and just when everything feels as bad is it can possibly feel, they’re told to say out loud—as sadly as possible—this single word:

    “Boop”

    It all but guarantees to result in cracking a smile, no matter the situation.

    Now this knowledge is yours too! Keep it secret! Or don’t. Sharing is caring.

  • How to keep your teeth young

    How to keep your teeth young

    The association between aging and teeth is so well-established that it’s entered popular idiom, “too long in the tooth”, and when it comes to visual representations, false teeth are well-associated with old age.

    And yet, avoiding such outcomes does not get anywhere near so much attention as, say, avoiding wrinkles or hair loss.

    At 10almonds, we’ve covered general dental health before, in a three-part series:

    1. Toothpastes & Mouthwashes: Which Help And Which Harm?
    2. Flossing, Better (And Easier!)
    3. Less Common Oral Hygiene Options

    Today, we’re going to be looking specifically at keeping our teeth young. What if you have lost your teeth already? Well, gum health remains important, and it’s foundational for everyone, so…

    Look after your gums first and last

    Hollywood’s most “perfect” whites would be nothing without the gums holding them in place. So, set aside the cosmetic whitening products that often harm gums (anything containing bleach / hydrogen peroxide, is generally a bad idea), andinstead focus on your gums.

    As for avoiding gum disease (periodontitis)?

    ❝In conclusion, periodontitis might enhance the association of biological aging with all-cause mortality in middle-aged and older adults.

    Hence, maintaining and enhancing periodontal health is expected to become an intervention to slow aging and extend life span.❞

    Source: Does Periodontitis Affect the Association of Biological Aging with Mortality?

    Ways to look after gum health include the obvious “floss” and “brush often” and “use fluoride toothpaste”, along with other options we covered in our “Less Common Oral Hygiene Options” article above.

    Also important: don’t smoke. It is bad for everything, and this is no exception.

    We expect we probably don’t have many subscribers who smoke, but if you do, please consider making quitting a priority.

    Consider supplementing with collagen

    Everyone’s all about the calcium and vitamin D for bones (and teeth), but a large part of the mass of both is actually collagen. And unlike calcium, which most people not living in a food desert get plenty of, or vitamin D, which is one of the most popular supplements around, collagen is something that gets depleted as we get older. We’ve written about its importance for bones:

    We Are Such Stuff As Fish Are Made Of—Collagen’s benefits are more than skin deep

    And as for its role in combatting gum disease and tooth loss:

    Nanoscale Dynamics of Streptococcal Adhesion to AGE-Modified Collagen

    By the way, that “AGE” there isn’t about chronological age; it’s about advanced glycation end-products. Those are also something you can and should avoid:

    Are You Eating AGEs?

    A different kind of “spit and polish”

    We imagine you have the “polishing” part in hand; that’s tooth-brushing, of course. But spit?

    Saliva is hugely important for our oral health, but it’s not something most of us think about a lot. For example, you might not have known (or might have known but not thought much about) that many common medications affect our saliva, including many blood pressure medications and antidepressants:

    Impact of ageing and drug consumption on oral health

    Because there are so many possibilities, this is the kind of thing to check with your pharmacist or doctor about. But as a rule, if you take a medication whose side-effects include “dry mouth”, this might be you.

    Here’s a really useful (academic) article that covers what drugs cause this, how to diagnose it, and what can be done about it:

    Hyposalivation in Elderly Patients

    If something’s difficult, find a way to make it easier

    Sometimes, as we get older, some things that used to be easy, aren’t. We can lose strength, coordination, manual dexterity, memory, attention, and more. Obviously, we try not to, and do what we can to keep ourselves in good health.

    But, if you do have some disability that makes for example brushing and/or flossing difficult to do consistently and/or well, consider talking to your doctor to see if there are assistive devices that can help, or some other kind of support that could allow you to do what you need to.

    There’s never any shame in getting help if we need it.

    Take care!

  • Dealing With Waking Up In The Night

    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

    ❝I’m now in my sixties and find that I invariably wake up at least once during the night. Is this normal? Even if it is, I would still like, once in a while, to sleep right through like a teenager. How might this be achieved, without pills?❞

    Most people wake up briefly between sleep cycles, and forget doing so. But waking up for more than a brief moment is indeed best avoided. In men of your age, if you’re waking to pee (especially if it’s then not actually that easy to pee), it can be a sign of an enlarged prostate. Which is again a) normal b) not optimal.

    By “without pills” we’ll assume you mean “without sleeping pills”. There are options to treat an enlarged prostate, including well-established supplements. We did a main feature on this:

    Prostate Health: What You Should Know

    If the cause of waking up is something else, then again this is common for everyone as we get older, and again it’s not optimal. But since there are so many possible causes (and thus solutions), it’s more than we can cover in less than a main feature, so we’ll have to revisit this later.

    Meanwhile, take care!

    First let’s be clear: this is about the US healthcare system, and thus will be mostly relevant for US Americans. Still, many outside of the US may have an interest, and in fact the book does talk about the healthcare systems of many other countries (hence the subtitle mentioning “a global quest”), outlining how each works, and what the journey was that got them there.

    The author, a veteran journalist with a 60+ year-long career, notes that affordable healthcare is a social problem so complex, that only 33 out of 32 of the world’s richest countries have managed to do it. That’s a little glib and can be quibbled in the minutiae, but when it comes down to it, insulin in the US still costs 50x what it does in most places, and in pretty much all aspects of healthcare, US Americans are being fleeced at every turn.

    He examines why this happens, and what currently prevents the US from lowering healthcare costs. He finds the culprits to be the profitmongers along the way (insurance companies in cahoots with drug companies in cahoots with hospitals, etc), as well as a pervasive belief that since healthcare is so expensive, how could the richest country on Earth possibly pay for it? Many Americans will believe that the answer is that other countries have inferior care, but this tends to stem from a mistaken belief that medical treatment actually costs what Americans are billed for it. The fact is: the same quality of care can be provided for a lot less, as many countries demonstrate.

    The book doesn’t argue for any one particular solution; it doesn’t have to be entirely state-funded like the UK, or consumer-funded but seriously low price caps like in Japan; there are many other models to choose from. The argument that is made is that if so many other countries can have medical bankruptcy being a thing unheard-of instead of the leading cause of bankruptcy, then so can the US, and here’s a wide menu of methods to choose from.

    Bottom line: if you’re a US American and you’d like to think you could get the same quality of care without lining numerous corporate pockets along the way with your hard-earned cash, then this book will open your eyes to what is possible.

  • Spinach vs Chard – 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 spinach to chard, we picked the spinach.

    Why?

    In terms of macros, spinach has slightly more fiber and protein, while chard has slightly more carbs. Now, those carbs are fine; nobody is getting metabolic disease from eating greens. But, by the numbers, this is a clear, albeit marginal, win for spinach.

    In the category of vitamins, spinach has more of vitamins A, B1, B2, B3, B5, B6, B9, E, and K, while chard has more of vitamins C and choline. An even clearer victory for spinach this time.

    When it comes to minerals, spinach has more calcium, copper, iron, magnesium, manganese, phosphorus, selenium, and zinc, while chard has more potassium. Once again, a clear win for spinach.

    You may be wondering about oxalates, in which spinach is famously high. However, chard is nearly 2x higher in oxalates. In practical terms, this doesn’t mean too much for most people. If you have kidney problems or a family history of such, it is recommended to avoid oxalates. For everyone else, the only downside is that oxalates diminish calcium bioavailability, which is a pity, as spinach is (by the numbers) a good source of calcium.

    However, oxalates are broken down by heat, so this means that cooked spinach (lightly steamed is fine; you don’t need to do anything drastic) will be much lower in oxalates (if you have kidney problems, do still check with your doctor/dietician, though).

    All in all, spinach beats chard by most metrics, and by a fair margin. Still, enjoy either or both, unless you have kidney problems, in which case maybe go for kale or collard greens instead!

  • Mung Beans vs Red Lentils – 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 mung beans to red lentils, we picked the lentils.

    Why?

    Both are great! But the lentils win on overall nutritional density.

    In terms of macros, they have approximately the same carbs and fiber, and are both low glycemic index foods. The deciding factor is that the lentils have slightly more protein—but it’s not a huge difference; both are very good sources of protein.

    In the category of vitamins, mung beans have more of vitamins A, E, and K, while red lentils have more of vitamins B1, B2, B3, B5, B6, B9, C, and choline. An easy win for lentils.

    When it comes to minerals, again both are great, but mung beans have more calcium and magnesium (hence the green color) while red lentils have more copper, iron, manganese, phosphorus, potassium, selenium, and zinc. Another clear win for lentils.

    Polyphenols are also a worthy category to note here; both have plenty, but red lentils have more, especially flavonols, anthocyanidins, proanthocyanidins, and anthocyanins (whence the red color).

    In short: enjoy both, because diversity is almost always best. But if you’re picking one, red lentils are the most nutritious of the two.
