When Bitter Is Better

A good general rule of thumb for “does this food contain a lot of healthy polyphenols?” is:

“is this (edible) plant bitter/astringent/pungent”?

If it is, it’s probably rich in polyphenols:

…which is why it’s no surprise that black coffee and bitter chocolate score highly, as do hot peppers and even garlic.

Even fruits, generally considered something sweet to eat, often contain more polyphenols when they are bitter—many berries are great examples of this!

You can read more about the science of this here:

Sensory Nutrition and Bitterness and Astringency of Polyphenols

Important for multiple reasons (including heart and brain health)

Polyphenols have many benefits, and they’re most well known for their heart-healthy properties, but their antioxidant effect (and other mechanisms) also means these foods are generally neuroprotectants too:

A century of research shows eating these compounds can help protect against heart disease and Alzheimer’s

The science of this is not all as obvious as you might think!

It is reasonable to expect “ok, this has antioxidant effect, so it will reduce oxidative damage to brain cells too”, and while that is true (and yes, polyphenols do cross the blood-brain barrier), they also help in other ways, including through the gut:

Where to Look into the Puzzle of Polyphenols and Health? The Postbiotics and Gut Microbiota Associated with Human Metabotypes

What if I don’t like bitter/astringent/pungent foods?

If you do not have a medical condition that proscribes them (do check with your doctor if unsure), the best advice is to simply eat them anyway, and your tastes will adapt.

It will also help if you avoid sweet foods (though this too is also a good general rule of thumb!), as this will move the balance of where your brain’s “set range” is for “good taste”.

Bonus tip: dark chocolate (80%+ cocoa if possible, 95% if you can get it) and chilli peppers go great with each other. Here’s an example of a chilli chocolate product on Amazon; it’s 70% cocoa (which is not bad, but could be better). You might be able to get a higher percentage locally, especially if you ask your local chocolatière, or make it yourself!

Enjoy!

  • Stretching to Stay Young – by Jessica Matthews

    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 stretching gurus (especially the Instagrammable kind) offer advices like “if you can’t do the splits balanced between two chairs to start with, that’s fine… just practise by doing the splits against a wall first!”

    Jessica Matthews, meanwhile, takes a more grounded approach. A lot of this is less like yoga and more like physiotherapy—it’s uncomplicated and functional. There’s nothing flashy here… just the promise of being able to thrive in your body; supple and comfortable, doing the activities that matter to you.

    On which note: the book gives advices about stretches for before and after common activities, for example:

    • a bedtime routine set
    • a pre-gardening set
    • a post-phonecall set
    • a level-up-your golf set
    • a get ready for dancing set

    …and many more. Whether “your thing” is cross-country skiing or knitting, she’s got you covered.

    The book covers the whole body from head to toe. Whether you want to be sure to stretch everything, or just work on a particular part of your body that needs special attention, it’s there… with beautifully clear illustrations (the front cover illustration is indicative of the style—note how the muscle being stretched is highlighted in orange, too) and simple, easy-to-understand instructions.

    All in all, we’re none of us getting any younger, but we sure can take some of our youth into whatever years come next. This is the stuff that life is made of!

  • Overcoming Gravity – by Steven Low

    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 author, a professional gymnast and coach with a background in the sciences, knows his stuff here. This is what it says on the tin: it’s rigorously systematic. It’s also the most science-based calisthenics book this reviewer has read to date.

    If you just wanted to know how to do some exercises, then this book would be very much overkill, but if you want to be able to go from no knowledge to expert knowledge, then the nearly 600 pages of this weighty tome will do that for you.

    This is a textbook, it’s a “the bible of…” style book, it’s the one that if you’re serious, will engage you thoroughly and enable you to craft the calisthenics-forged body you want, head to toe.

    As if it weren’t already overdelivering, it also has plenty of information on injury avoidance (or injury/condition management if you have some existing injury or chronic condition), and building routines in a dynamic fashion that avoids becoming a grind, because it’s going from strength to strength while cycling through different body parts.

    Bottom line: if you’d like to get serious about calisthenics, then this is the book for you.

    Putting The Abs Into Absurdity

    We’ve talked before about the health benefits of a broadly positive outlook on life:

    Optimism Seriously Increases Longevity!

    …and we’re very serious about it, but that’s about optimistic life views in general, and today we’re about not just keeping good humor in questionable circumstances, but actively finding good humor in the those moments—even when the moments in question might not be generally described as good!

    After all, laughter really can be the best medicine, for example:

    The effect of laughter yoga exercises on anxiety and sleep quality in patients suffering from Parkinson’s disease

    From the roots

    First a quick recap on de-toothing the psychological aspect of threats, no matter how menacing they may be:

    Hello, Emotions: Time For Radical Acceptance!

    …which we can then take a step further:

    What’s The Worst That Could Happen?

    Choose your frame

    Do you remember when that hacker hacked and publicized the US Federal no-fly list, after already hacking a nationwide cloud-based security camera company, getting access to more than 150,000 companies’ and private individuals’ security cameras, amongst various other cyber crimes, mostly various kinds of fraud and data theft?

    Imagine how she (age 21) must have felt, when being indicted. What do you suppose this hacker had to say for itself under such circumstances?

    ❝congress is investigating now 🙂

    but i stay silly :3 ❞

    ~ maia arson crimew

    …the latter half of which, usually rendered “but I stay silly” or “but we stay silly” has since entered popular Gen-Z parlance, usually after expressing some negative thing, often in a state of powerlessness.

    Which is an important life skill if powerlessness is something that is often likely.

    It’s important for many Gen-Zs with negligible life prospects economically; it’s equally important for 60-somethings getting cancer diagnoses (statistically the most likely decade to find out one has cancer, by the way), and many other kinds of people younger, older, and in between.

    Because at the end of the day, we all start powerless and we all end powerless.

    Learned helplessness (two kinds)

    In psychology, “learned helplessness” occurs when a person or creature gives up after learning that all and any attempts to resist a Bad Thing™ fail, perhaps even badly. A lab rat may just shut down and sit there getting electroshocked, for example. A person subjected to abuse may stop trying to improve their situation, and just go with the path of least resistance.

    But, there’s another kind, wherein someone in a position of absolute powerlessness not only makes their peace with that, but also, decides that the one thing the outside world can’t control, is how they take it. Like the hacker we mentioned earlier.

    Sometimes the gallows humor is even more literal, laughing at one’s own impending death. Not as a matter of bravado, but genuinely seeing the funny side.

    But how?

    Unfortunately, fortunately

    The trick here is to “find a silver lining” that is nowhere near enough to compensate for the bad thing—and it may even be worse! But that’s fine:

    Unfortunately, I didn’t have time to do the dishes before leaving for my vacation. Fortunately, I also forgot to turn the oven off, so the house burning down covered up my messy kitchen”

    Writer’s personal less drastic example: today I set my espresso machine to press me an espresso; it doesn’t have an auto-off and I got distracted and it overflowed everywhere; my immediate reaction was “Oh! I have been blessed with an abundance of coffee!”

    This kind of silly little thing, on a daily basis, builds a very solid habit for life that allows one to see the funny side in even the most absurd situations, even matters of life and death (can confirm: been there enough times personally—so far so good, still alive to find the remembered absurdity silly).

    The point is not to genuinely value the “silver lining”, because half the time it isn’t even one, really, and it is useless to pretend, in seriousness.

    But to pretend in silliness? Now we’re onto something, and the real benefit is in the laughs we had along the way.

    Because those worst moments? Are probably when we need it the most, so it’s good to get some practice in!

    Want more ways to find the funny and make it a life habit?

    We reviewed a good book recently:

    Turns out the viral ‘Sleepy Girl Mocktail’ is backed by science. Should you try it?

    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.

    Many of us wish we could get a better night’s sleep. Wouldn’t it be great if it was as easy as a mocktail before bed?

    That’s what the latest viral trend might have us believe. The “Sleepy Girl Mocktail” is a mix of tart cherry juice, powdered magnesium supplement and soda water. TikTok videos featuring the concoction have garnered hundreds of thousands of views. But, what does the science say? Do these ingredients actually help us sleep?

    Tart cherry juice

    There is research to show including tart cherry juice in your diet improves overall sleep. Clinical trials show tart cherry juice increases sleep quality and quantity, as well as a lessening insomnia symptoms (compared to a placebo). This could be due to the presence of melatonin, a sleep-promoting hormone, in cherries.

    Tart cherry varieties such as Jerte Valley or Montmorency have the highest concentration of melatonin (approximately 0.135 micrograms of melatonin per 100g of cherry juice). Over the counter melatonin supplements can range from 0.5 milligram to over 100 milligrams, with research suggesting those beginning to take melatonin start with a dose of 0.5–2 milligrams to see an improvement in sleep.

    Melatonin naturally occurs in our bodies. Our body clock promotes the release of melatonin in the evening to help us sleep, specifically in the two hours before our natural bedtime.

    If we want to increase our melatonin intake with external sources, such as cherries, then we should be timing our intake with our natural increase in melatonin. Supplementing melatonin too close to bed will mean we may not get the sleep-promoting benefits in time to get off to sleep easily. Taking melatonin too late may even harm our long-term sleep health by sending the message to our body clock to delay the release of melatonin until later in the evening.

    Magnesium – but how much?

    Magnesium also works to promote melatonin, and magnesium supplements have been shown to improve sleep outcomes.

    However, results vary depending on the amount of magnesium people take. And we don’t yet have the answers on the best dose of magnesium for sleep benefits.

    We do know magnesium plays a vital role in energy production and bone development, making it an important daily nutrient for our diets. Foods rich in magnesium include wheat cereal or bread, almonds, cashews, pumpkin seeds, spinach, artichokes, green beans, soy milk and dark chocolate.

    Bubbly water

    Soda water serves as the base of the drink, rather than a pathway to better sleep. And bubbly water may make the mix more palatable. It is important to keep in mind that drinking fluids close to bedtime can be disruptive to our sleep as it might lead to waking during the night to urinate.

    Healthy sleep recommendations include avoiding water intake in the two hours before bed. Having carbonated beverages too close to bed can also trigger digestive symptoms such as bloating, gassiness and reflux during the night.

    Bottoms up?

    Overall, there is evidence to support trying out the Sleepy Girl Mocktail to see if it improves sleep, however there are some key things to remember:

    • timing: to get the benefits of this drink, avoid having it too close to bed. Aim to have it two hours before your usual bedtime and avoid fluids after this time

    • consistency: no drink is going to be an immediate cure for poor sleep. However, this recipe could help promote sleep if used strategically (at the right time) and consistently as part of a balanced diet. It may also introduce a calming evening routine that helps your brain relax and signals it’s time for bed

    • maximum magnesium: be mindful of the amount of magnesium you are consuming. While there are many health benefits to magnesium, the recommended daily maximum amounts are 420mg for adult males and 320mg for adult females. Exceeding the maximum can lead to low blood pressure, respiratory distress, stomach problems, muscle weakness and mood problems
    • sugar: in some of the TikTok recipes sugar (as flavoured sodas, syrups or lollies) is added to the drink. While this may help hide the taste of the tart cherry juice, the consumption of sugar too close to bed may make it more difficult to get to sleep. And sugar in the evening raises blood sugar levels at a time when our body is not primed to be processing sugar. Long term, this can increase our risk of diabetes

    • sleep environment: follow good sleep hygiene practices including keeping a consistent bedtime and wake time, a wind-down routine before bed, avoiding electronic device use like phones or laptops in bed, and avoiding bright light in the evening. Bright light works to suppress our melatonin levels in the evening and make us more alert.

    What about other drinks?

    Other common evening beverages include herbal tisanes or teas, hot chocolate, or warm milk.

    Milk can be especially beneficial for sleep, as it contains the amino acid tryptophan, which can promote melatonin production. Again, it is important to also consider the timing of these drinks and to avoid any caffeine in tea and too much chocolate too close to bedtime, as this can make us more alert rather than sleepy.

    Getting enough sleep is crucial to our health and wellbeing. If you have tried multiple strategies to improve your sleep and things are not getting better, it may be time to seek professional advice, such as from a GP.

  • All About Olive Oil

    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 😎

    ❝Skip the video & tell more about olive oil please.❞

    We love requests!

    We can’t really do anti-requests (e.g. “skip the video”) because for every one person who doesn’t care for one particular element of the newsletter, there will be thousands who do—and indeed, the video segment is a popular one, so it will certainly remain.

    However! Let us reassure you that you personally are not obliged to watch the video if you don’t want to 🙂 In fact, our general hope with 10almonds is that there will be at least one feature that is of value to each reader, each day.

    Writer’s note: I’m a very bookish person, and in honesty do not love videos personally either. You know what I do love though? Olive oil. So let’s get onto that 😎

    Why olive oil?

    Let’s quickly address the taste/culinary side of things first, and then spend more time on the health aspects. Olive oil’s strong punchy flavor (as oils go, anyway) makes it a big winner with those of us who love strong punchy flavors. However, it does mean that it can overwhelm some more delicate dishes if one isn’t careful, meaning that it’s not perfect for everything all the time.

    Healthwise, olive oil is one of the healthiest oils around, along with avocado oil. In fact, we compared them previously:

    Avocado Oil vs Olive Oil – Which is Healthier?

    …and it’s worth noting that their (excellent) lipids profiles are very similar, meaning that the main factor between them is that olive oil usually retains vitamins that avocado oil doesn’t.

    Meanwhile, another popular contender for “healthy oil” is coconut oil, but this doesn’t have nearly as unambiguously good a lipids profile, because of coconut oil’s high saturated fat content—though lauric acid can have a cardioprotective effect, so the jury is out on that one:

    Olive Oil vs Coconut Oil – Which is Healthier?

    Interestingly, this article from The Conversation considered seed oils (canola, sunflower, sesame) to be next-best options:

    I can’t afford olive oil. What else can I use?

    …but it’s worth noting that the way those seed oils are made varies a lot from country to country, and can affect their health impact considerably.

    It’s not just about the fats

    Olives, especially green olives with their stronger more pungent flavor, are rich in assorted polyphenols that have many health-giving properties:

    Black Olives vs Green Olives – Which is Healthier

    …and olive oil is almost always made from green olives. Note that while we picked black olives in the above comparison, that’s mainly because green olives are “cured” for longer and thus are much higher in sodium… Which, guess what, isn’t in olive oil, so with olive oil we can enjoy all of the polyphenols with almost none of the sodium!

    Let’s talk virginity

    When it comes to olive oil, definitely not everything labelled as olive oil in the supermarket is of the same quality. Mostly, however, it’s not whether it’s “extra virgin” (i.e. the oil from the first mechanical pressing) or not that actually makes the biggest health difference, so much as that olive oils are often adulterated with other cheaper oils, so it’s important to check labels for that, even when they say “extra virgin”, in case it’s something like:

    a blend of
    EXTRA VIRGIN OLIVE OIL
    and other oils

    We talk about this, and the various different levels of quality of olive oil and how you can tell them apart for yourself in the supermarket (and be wise to the ways they may try to trick you), here:

    Is “Extra Virgin” Worth It?

    What to enjoy it with?

    Olive oil is the single largest source of fat in the Mediterranean diet, and by that we mean not just “food that is eaten in the Mediterranean”, but rather, the well-defined dietary approach that has for a long time now been considered “the gold standard” of what a healthy diet looks like, scientifically. You can read more about what is and isn’t included in the definition, here:

  • The Dangers Of Fires, Floods, & Having Your Hair Washed

    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 a dangerous business, going out of your door… And this week’s news round-up looks at 5 reasons why that might be:

    Superspreading like wildfire

    Environmental health risks are a big topic these days, with our changing climate. As for wildfires? Some of the risks are obvious: burning to death or choking to death in the smoke—but even upon surviving the seemingly worst, more threats remain that themselves can still kill.

    Those threats include that both burns and smoke inhalation can cause acute and chronic changes in the immune system. Specifically: changes for the worse. The mechanisms by which this happens depend on the nature of any burns received, and in the case of smoke, what exactly was in the smoke. Now, there is no kind of smoke that is healthy to inhale, but definitely some kinds are a lot worse than others, and let’s just say, people’s homes contain a lot of plastic.

    Additionally, if you think someone coughing near you spreads germs, imagine how far germs can be spread by miles-high, miles-wide billowing hot air.

    In short, there’s a lot going on and none of it is good, and we’ve barely had room to summarise here, so…

    A flood of diseases

    *record scratch*

    Environmental health risks are a big topic these days, with our changing climate. As for floods? Some of the risks are obvious: drowning to death or having your house washed away—but even upon surviving the seemingly worst, more threats remain that themselves can still kill.

    Those threats include increases in deaths from infectious and parasitic diseases, and respiratory diseases in general. Simply, a place that has been waterlogged, even if it seems “safe” now, is not a healthy place to be, due to bacteria, viruses, fungi, and more. In fact, it even increases all-cause mortality, because being healthy in such a place is simply harder:

    Don’t lose your head

    Visiting the hairdresser is not something that most people consider a potential brush with death—your hairdresser is probably not Sweeney Todd, after all. However…

    There is an issue specifically with getting your hair washed there. Backwash basins—the sink things into which one rests one’s head at a backwards tilt—create an awkward angle for the cervical vertebrae and a sudden reduction in blood flow to the brain can cause a stroke, with the risk being sufficiently notable as to have its own name in scientific literature: beauty parlor stroke syndrome (BPSS).

    ❝While research suggests BPSS is most likely to occur in women over 50—and previous history of narrowing or thinning of blood vessels and arthritis of the spinal column in the neck are particular risk factors—it could happen to anyone regardless of age or medical history.❞

    The smartwatch wristbands that give you cancer

    It’s about the PFAS content. The article doesn’t discuss cancer in detail, just mentioning the increased risk, but you can read about the link between the two in our article below.

    Basically, if your smartwatch wristband is a) not silicone and b) waterproof anyway, especially if it’s stain-resistant (as most are designed to be, what with wearing it next to one’s skin all the time while exercising, and not being the sort of thing one throws in the wash), then chances are it has PFAS levels much higher than normally found in consumer goods or clothing.

    The cows giving milk with a little extra

    Bird flu (HPAI) is now not the only flu epidemic amongst cattle in the US, and not only that, but rather than “merely” colonizing the lungs and upper respiratory tracts, in this case the virus (IAV) is thriving in the mammary glands, meaning that yes, it gets dispensed into the milk, and so far scientists are simply scrambling to find better ways to vaccinate the cattle, in the hopes that the milk will not be so risky because yes, it is currently a “reservoir and transmission vector” for the virus.

    There are, however, barriers to creating those vaccines:
