Beating The Insomnia Blues

You previously asked us about recipes for insomnia (or rather, recipes/foods to help with easing insomnia). We delivered!

But we also semi-promised we’d cover a bit more of the general management of insomnia, because while diet’s important, it’s not everything.

Sleep Hygiene

Alright, you probably know this first bit, but we’d be remiss if we didn’t cover it before moving on:

  • No caffeine or alcohol before bed
    • Ideally: none earlier either, but if you enjoy one or the other or both, we realize an article about sleep hygiene isn’t going to be what changes your mind
  • Fresh bedding
    • At the very least, fresh pillowcase(s). While washing and drying an entire bedding set constantly may be arduous and wasteful of resources, it never hurts to throw your latest pillowcase(s) in with each load of laundry you happen to do.
  • Warm bed, cool room = maximum coziness
  • Dark room. Speaking of which…

About That Darkness…

When we say the room should be dark, we really mean it:

  • Not dark like “evening mood lighting”, but actually dark.
  • Not dark like “in the pale moonlight”, but actually dark.
  • Not dark like “apart from the light peeking under the doorway”, but actually dark.
  • Not dark like “apart from a few LEDs on electronic devices that are on standby or are charging”, but actually dark.

There are many studies about the impact of blue light on sleep, but here’s one as an example.

If blue light with wavelength between 415 nm and 455 nm (in the visible spectrum) hits the retina, melatonin (the sleep hormone) will be suppressed.

The extent of the suppression is proportional to the amount of blue light. This means that there is a difference between starting at an “artificial daylight” lamp, and having the blue LED of your phone charger showing… but the effect is cumulative.

And it gets worse:

❝This high energy blue light passes through the cornea and lens to the retina causing diseases such as dry eye, cataract, age-related macular degeneration, even stimulating the brain, inhibiting melatonin secretion, and enhancing adrenocortical hormone production, which will destroy the hormonal balance and directly affect sleep quality.❞

Read it in full: Research progress about the effect and prevention of blue light on eyes

See also: Age-related maculopathy and the impact of blue light hazard

So, what this means, if we value our health, is:

  • Switch off, or if that’s impractical, cover the lights of electronic devices. This might be as simple as placing your phone face-down rather than face-up, for instance.
  • Invest in blackout blinds/curtains (per your preference). Serious ones, like these ← see how they don’t have to be black to be blackout! You don’t have to sacrifice style for function
  • If you can’t reasonably do the above, consider a sleep mask. Again, a good one. Not the kind you were given on a flight, or got free with some fluffy handcuffs. We mean a full-blackout sleep mask that’s designed to be comfortable enough to sleep in, like this one.
  • If you need to get up to pee or whatever, do like a pirate and keep one eye covered/closed. That way, it’ll remain unaffected by the light. Pirates did it to retain their night vision when switching between being on-deck or below, but you can do it to halve the loss of melatonin.

Lights-Out For Your Brain Too

You can have all the darkness in the world and still not sleep if your mind is racing thinking about:

  • your recent day
  • your next day
  • that conversation you wish had gone differently
  • what you really should have done when you were 18
  • how you would go about fixing your country’s socio-political and economic woes if you were in charge
  • Etc.

We wrote about how to hit pause on all that, in a previous edition of 10almonds.

  • How To Gain Weight (Healthily!)

    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.

    What Do You Have To Gain?

    We have previously promised a three-part series about changing one’s weight:

    1. Losing weight (specifically, losing fat)
    2. Gaining weight (specifically, gaining muscle)
    3. Gaining weight (specifically, gaining fat)

    There will be, however, no need for a “losing muscle” article, because (even though sometimes a person might have some reason to want to do this), it’s really just a case of “those things we said for gaining muscle? Don’t do those and the muscle will atrophy naturally”.

    Here’s our first article: How To Lose Weight (Healthily!)

    While some people will want to lose fat, please do be aware that the association between weight loss and good health is not nearly so strong as the weight loss industry would have you believe:

    Shedding Some Obesity Myths

    And, while BMI is not a useful measure of health in general, it’s worth noting that over the age of 65, a BMI of 27 (which is in the high end of “overweight”, without being obese) is associated with the lowest all-cause mortality:

    BMI and all-cause mortality in older adults: a meta-analysis

    Here was our second article: How To Build Muscle (Healthily!)

    And now, it’s time for the last part, which yes, is also something that some people want/need to do (healthily!), and want/need help with that.

    How to gain fat, healthily

    Fat gets a bad press, but when it comes to health, we would die without it.

    Even in the case of having excess fat, the fat itself is not generally the problem, so much as comorbid metabolic issues that are often caused by the same things as the excess fat.

    So, how to gain fat healthily?

    • Obvious but potentially dangerously misleading answer: “in moderation”
    • More useful answer: “carefully”

    Because, you can “in moderation” put on less than one pound per week for a few years and be in very bad health by the end of it. So how does this “carefully” work any differently to “in moderation”?

    The key is in how we store the fat

    Not merely where we store it (though that’ll follow from the “how”), but specifically: how we store it.

    • When we consume energy from food in excess of our immediate survival needs, our body stores what it can. This is good!
    • When our body is receiving energy from food faster than it can physically process it to store it healthily, it will start shoving it wherever it can instead. This is bad!

    This is the physiological equivalent of the difference between tidying a room carefully, and cramming everything into one cupboard in 30 seconds just to get it out of sight.

    So, you do need to consume calories yes, but you need to consume them in a way your body can take its time about storing them.

    We’ve written before about the science of this, so we’ll share some links to that in a moment, but first, here are the practical tips:

    • Do not drink your calories. Drinking calories tends to be the equivalent of injecting sugars directly into your veins, in terms of how quickly it gets received.
      • See also: How To Unfatty A Fatty Liver ← this is highly relevant, because the same process that results in unhealthy weight gain, results in liver disease, by the same mechanism (the liver gets overwhelmed).
    • Eat your greens. No, they won’t provide many calories, but they are critical to your body not being overwhelmed by the arrival of sugars.
      • See also: 10 Ways To Balance Blood Sugars ← the other 9 things are also helpful for not putting on fat unhealthily, so using these alongside a calorie-dense diet can result in healthy fat gain as needed
    • Get more of your calories from fats than carbs. Fats will not overwhelm your body’s glycemic response in the same way that carbs will.
    • Consider going low-carb, but even if you choose not to, go for carbs with a low glycemic index instead of a high glycemic index.
    • Need healthy fats in a snack? Enjoy nuts (unless you have an allergy); they will be your best friend in this regard. As an example, a mere 1oz portion of cashew nuts has 157 calories.
    • Need health fats for cooking? Enjoy olive oil, as it has one of the healthiest lipids profiles available, and is a great way to increase the calorific content of many meals.

    Lastly…

    Be patient, enjoy your food, and stick as best you can to the above considerations. All strength to you.

    Take care!

  • Our Top 5 Spices: How Much Is Enough For Benefits?

    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 spoonful of pepper makes the… Hang on, no, that’s not right…

    We know that spices are the spice of life, and many have great health-giving qualities. But…

    1. How much is the right amount?
    2. What’s the minimum to get health benefits?
    3. What’s the maximum to avoid toxicity?

    That last one always seems like a scary question, but please bear in mind: everything is toxic at a certain dose. Oxygen, water, you-name-it.

    On the other hand, many things have a toxicity so low that one could not physically consume it sufficiently faster than the body eliminates it, to get a toxic build-up.

    Consider, for example, the €50 banknote that was nearly withdrawn from circulation because one of the dyes used in it was found to be toxic. However, the note remained in circulation after scientists patiently explained that a person would have to eat many thousands of them to get a lethal dose.

    So, let’s address these questions in reverse order:

    What’s the maximum to avoid toxicity?

    In the case of the spices we’ll look at today, the human body generally* has high tolerance for them if eaten at levels that we find comfortable eating.

    *IMPORTANT NOTE: If you have (or may have) a medical condition that may be triggered by spices, go easier on them (or if appropriate, abstain completely) after you learn about that.

    Check with your own physician if unsure, because not only are we not doctors, we’re specifically not your doctors, and cannot offer personalized health advice.

    We’re going to be talking in averages and generalizations here. Caveat consumator.

    For most people, unless you are taking the spice in such quantities that you are folding space and seeing the future, or eating them as the main constituents of your meal rather than an embellishment, you should be fine. Please don’t enter a chilli-eating contest and sue us.

    What is the minimum to get health benefits and how much should we eat?

    The science of physiology generally involves continuous rather than discrete data, so there’s not so much a hard threshold, as a point at which the benefits become significant. The usefulness of most nutrients we consume, be they macro- or micro-, will tend to have a bell curve.

    In other words, a tiny amount won’t do much, the right amount will have a good result, and usefulness will tail off after that point. To that end, we’re going to look at the “sweet spot” of peaking on the graph.

    Also note: the clinical dose is the dose of the compound, not the amount of the food that one will need to eat to get that dose. For example, food x containing compound y will not usually contain that compound at 100% rate and nothing else. We mention this so that you’re not surprised when we say “the recommended dose is 5mg of compound, so take a teaspoon of this spice”, for example.

    Further note: we only have so much room here, so we’re going to list only the top benefits, and not delve into the science of them. You can see the related main features for more details, though!

    The “big 5” health-giving spices, with their relevant active compound:

    • Black pepper (piperine)
    • Hot pepper* (capsaicin)
    • Garlic (allicin)
    • Ginger (gingerol)
    • Turmeric (curcumin**)

    *Cayenne pepper is very high in capsaicin; chilli peppers are also great

    **not the same thing as cumin, which is a completely different plant. Cumin does have some health benefits of its own, but not in the same league as the spices above, and there’s only so much we have room to cover today.

    Black pepper

    • Benefits: antioxidant, anti-cancer, boosts bioavailability of other nutrients, aids digestion
    • Dosage: 5–20mg for benefits
    • Suggestion: ½ teaspoon of black pepper is sufficient for benefits. However, this writer’s kitchen dictum in this case is “if you can’t see the black pepper in/on the food, add more”—but that’s more about taste!
    • Related main feature: Black Pepper’s Anti-Cancer Arsenal (And More)

    Hot Pepper

    Garlic

    • Benefits: heart health, blood sugar balancing, anti-cancer
    • Dosage: 4–8µg for benefits
    • Suggestion: 1–2 cloves daily is generally good. However, cooking reduces allicin content (and so does oxidation after cutting/crushing), so you may want to adjust accordingly if doing those things.
    • Related main feature: The Many Health Benefits Of Garlic

    Ginger

    • Benefits: anti-inflammatory, antioxidant, anti-nausea
    • Dosage: 3–4g for benefits
    • Suggestion: 1 teaspoon grated raw ginger or ½ a teaspoon powdered ginger, can be used in baking or as part of the seasoning for a stir-fry
    • Related main feature: Ginger Does A Lot More Than You Think

    Turmeric

    Closing notes

    The above five spices are very healthful for most people. Personal physiology can and will vary, so if in doubt, a) check with your doctor b) start at lowest doses and establish your tolerance (or lack thereof).

    Enjoy, and stay well!

  • Cashews 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 cashews to peanuts, we picked the peanuts.

    Why?

    Another one for “that which is more expensive is not necessarily the healthier”! Although, certainly both are good:

    In terms of macros, cashews have about 2x the carbs while peanuts have a little more (healthy!) fat and more than 2x the fiber, meaning that peanuts also enjoy the lower glycemic index. All in all, a fair win for peanuts here.

    When it comes to vitamins, cashews have more of vitamins B6 and K, while peanuts have a lot more of vitamins B1, B2, B3, B5, B7, B9, and E. Another easy win for peanuts.

    In the category of minerals; cashews have more copper, iron, magnesium, phosphorus, and selenium, while peanuts have more calcium, manganese, and potassium. A win for cashews, this time.

    Adding up the sections makes for an overall win for peanuts, but (assuming you are not allergic) enjoy either or both! In fact, enjoying both is best; diversity is good.

    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!

    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.

    There are times when you do really need a doctor, not a dietician. But there are also times when a doctor will prescribe something for the symptom, leaving the underlying issue untouched. If only there were a way to have the best of both worlds!

    That’s where Drs. Rao and Aggarwal come in. They’re both medical doctors… with a keen interest in nutrition and healthy lifestyle changes to make us less sick such that we have less need to go to the doctor at all.

    Best of all, they understand—while some things are true for everyone—there’s not a one-size-fits all diet or exercise regime or even sleep setup.

    So instead, they take us hand-in-hand (chapter by chapter!) through the various parts of our life (including our diet) that might need tweaking. Each of these changes, if taken up, promise a net improvement that becomes synergistic with the other changes. There’s a degree of biofeedback involved, and listening to your body, to be sure of what’s really best for you, not what merely should be best for you on paper.

    The writing style is accessible while science-heavy. They don’t assume prior knowledge, and/but they sure deliver a lot. The book is more text than images, but there are plenty of medical diagrams, explanations, charts, and the like. You will feed like a medical student! And it’s very much worth studying.

    Bottom line: highly recommendable even if you don’t have inflammation issues, and worth its weight in gold if you do.

  • Beetroot vs Pumpkin – 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 beetroot to pumpkin, we picked the beetroot.

    Why?

    It was close! And an argument could be made for either.

    In terms of macros, beetroot has about 3x more protein and about 3x more fiber, as well as about 2x more carbs, making it the “more food per food” option. While both have a low glycemic index, we picked the beetroot here for its better numbers overall.

    In the category of vitamins, beetroot has more of vitamins B6 and B9, while pumpkin has more of vitamins A, B2, B3, B5, E, and K. So, a fair win for pumpkin this time.

    When it comes to minerals, though, beetroot has more calcium, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while pumpkin has a tiny bit more copper. An easy win for beetroot here.

    In short, both are great, and although pumpkin shines in the vitamin category, beetroot wins on overall nutritional density.
