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

❝Do we really need pores, and why are they bigger on the face?❞

Pores secrete sweat or sebum (there are different kinds of pores for each).

If we didn’t have sweat pores, we’d be unable to sweat, which superficially may seem like a bonus, but it’d make us prone to overheating (like dogs, pigs, and other mammals that cannot sweat).

If we didn’t have sebum pores (usually called hair follicles, which are supplied by a sebaceous gland), we’d be completely hairless, and also unable to supply our skin with natural oils that keep it healthy. So we’d have no hair and very unhappy skin.

Which is ironic, because to believe beauty magazines, we must at all costs minimize our pores (and indeed, interventions like botox* can kill them).

*Let’s give that its full name though:

Botulinum Neurotoxin Type A in the Treatment of Facial Seborrhea and Acne: Evidence and a Proposed Mechanism

Suffice it to say, we do not recommend getting injected with neurotoxins unless it is truly necessary to ward off a greater harm.

As for being bigger on the face, they need not be, but sebaceous glands are more active and numerous there, being most active and numerous in the face/forehead—which is why oily skin is more likely to appear there than other parts of the body.

If your facial sebaceous glands are too active for your liking…

…there are ways to reduce that, a simple and relatively gentle way (relative, for example, botox) is with retinoids, including retinols or retinoic acids. Here’s some of the science of that; the paper is about treating acne, but the mechanism of action is the same (down-regulating the sebaceous glands’ action):

The treatment of severe cystic acne with 13-cis-retinoic acid: evaluation of sebum production and the clinical response in a multiple-dose trial

The potential side-effects, however were noted as:

  • Cheilitis
  • Desquamation of the skin
  • Pruritus

Which, in translation from sciencese, means:

  • Chapped lips
  • Flaky skin
  • Itchiness

Which aren’t necessarily fun, which is why with retinoids are best taken in very small doses at first to see how your skin reacts.

Remember when we said what your skin would be like without pores? This is what would happen, only much worse.

Take care!

  • Stand Up For Your Health (Or Don’t)

    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.

    You may have heard the phrase “sitting is the new smoking”, and while the jury’s out on whether that’s accurate or not in terms of exactly how damaging it is, one thing that is universally agreed-upon is that sitting is indeed very bad.

    It’s especially bad for your spine (because of being folded in ways it shouldn’t be), your muscles and associated nerves of the lower back and hip area, your abdominal organs (because of being compressed in ways they shouldn’t be), and your heart (because of arteries and veins being squashed up in ways they shouldn’t be), and if you remember how “what’s good for your heart is good for your brain”, the inverse is true, and what’s bad for your heart is also bad for your brain, which won’t get nourished with oxygen and nutrients and which won’t have its detritus removed as efficiently as it should; that’ll be left to build up in the brain instead.

    First, elephant in the room: not everybody can stand, and of those who can, not everybody can stand for long. So obviously, work within what’s attainable for you.

    Also note that while sitting is the disease-bringer/worsener, standing isn’t the only solution, for example:

    • Walking is better than standing. You may be wondering: “who can’t stand but can walk?” and the answer is, a lot of people with certain kinds of chronic pain, for whom walking is less chronic-pain-exacerbating than standing, because the human body is built for movement and inactivity can worsen things even more than movement.
    • Lying down is better than sitting. One of the major problems with sitting is that your organs are all bunched up in ways they shouldn’t be. Lying down is, in this regard, closer to standing than sitting, because your body has a nice straight line to it.
    • Sitting can be made less bad! For example:
      • Sitting in a recliner chair in the reclined position is… Not great, if you’re then tilting your skull forwards to compensate, but if you’re just sitting back and relaxing, this is a lot better than sitting in the usual seated position, because again, it’s closer to lying down, which is closer to standing.
      • Sitting in seiza (the traditional Japanese kneeling position) is, provided you do it correctly and with good posture, better than sitting in the traditional Western manner. The reason for this is simple: instead of having your torso and legs at 90°, they are at 120°ish, give or take the size of your thighs and butt (bigger being better in this regard), and even that angle can be made even better if you use a meditation bench like this one ← we’re eyeballing it and didn’t get out a protractor, but if you look at the model’s torso and thighs, that’s about 135° difference, which is huge improvement over the 90° you get while sitting Western-style.

    For most of us a lot of the time though, we can stand to sit less. Think about the places you most often sit, and what can be done to reasonably minimize those, for example:

    • Car: minimize driving (or being a passenger in a car); walk where reasonably possible. Public transport, if available, may have standing options.
    • Office: a standing desk is, of course, the way to go. You can even use a standing desk converter, like this one. Just make sure to set it at the correct height, both in terms of where the keyboard and mouse go (the same height as your elbows are when your arms are dropped to your sides), and where the monitor goes (center of the monitor should be at eye-level).
      • Note: laptops will never be right for this, unless the natural resting distance between your elbows and your eyes is about 4½ inches, which will only be the case if your total height is approximately 1 foot and 2 inches. For anyone taller than that, laptops are still great to have when on the move and as a backup, but not great for ergonomics.
      • Workaround: if for some reason you must use a laptop for your day-to-day work, consider using a bluetooth keyboard so that you can still set them the appropriate height-distance apart and thus not have to hunch over them.
    • Dining room: sitting to eat a main meal is reasonable, but consider standing options for lighter bites; a standing-height “brunch bar” is great if you can arrange one.
    • Lounge: let it live up to its name, and actually lounge: if you’re not going to stand, then horizontal lounging is an improvement over sitting—as is sitting on the floor, and changing your position frequently. Who knew, kids had it right in that regard!
      • Note: if, like this writer, you do a lot of reading, the same applies regardless of which room you’re doing it in.
    • Bedroom: a culprit for many will be sitting while doing a beauty routine and/or possibly make-up. Easily avoided if you set a well-lit mirror at the correct height to use while standing.
      • Note: at the correct height though! While hunching up over a wall-mounted mirror is an improvement over hunching up at a seated vanity, it’s not a great improvement. You want to be able to stand with good posture and do it comfortably.
    • Bathroom: leave your phone outside—which is also a good approach for avoiding hemorrhoids! See also: Half Of Americans Over 50 Have Hemorrhoids, But They Can Be Prevented!

    Want to know more?

    We reviewed this book recently, which goes into all of the above in much more detail than we have room for here, plus also discusses a lot of social reframes that can be used (since a lot of sitting is a matter of social expectations, not actual need). It’s a very useful read:

  • Breakfasting For Health?

    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.

    Breakfast Time!

    In yesterday’s newsletter, we asked you for your health-related opinions on the timings of meals.

    But what does the science say?

    Quick recap on intermittent fasting first:

    Today’s article will rely somewhat on at least a basic knowledge of intermittent fasting, what it is, and how and why it works.

    Armed with that knowledge, we can look at when it is good to break the fast (i.e. breakfast) and when it is good to begin the fast (i.e. eat the last meal of the day).

    So, if you’d like a quick refresher on intermittent fasting, here it is:

    Intermittent Fasting: We Sort The Science From The Hype

    And now, onwards!

    One should eat breakfast first thing: True or False?

    True! Give or take one’s definition of “first thing”. We did a main feature about this previously, and you can read a lot about the science of it, and see links to studies:

    The Circadian Rhythm: Far More Than Most People Know

    In case you don’t have time to read that now, we’ll summarize the most relevant-to-today’s-article conclusion:

    The optimal time to breakfast is around 10am (this is based on getting sunlight around 8:30am, so adjust if this is different for you)

    It doesn’t matter when we eat; calories are calories & nutrients are nutrients: True or False?

    Broadly False, for practical purposes. Because, indeed calories are calories and nutrients are nutrients at any hour, but the body will do different things with them depending on where we are in the circadian cycle.

    For example, this study in the Journal of Nutrition found…

    ❝Our results suggest that in relatively healthy adults, eating less frequently, no snacking, consuming breakfast, and eating the largest meal in the morning may be effective methods for preventing long-term weight gain.

    Eating breakfast and lunch 5-6 h apart and making the overnight fast last 18-19 h may be a useful practical strategy.❞

    ~ Dr. Hana Kahleova et al.

    Read in full: Meal Frequency and Timing Are Associated with Changes in Body Mass Index

    We should avoid eating too late at night: True or False?

    False per se, True in the context of the above. Allow us to clarify:

    There is nothing inherently bad about eating late at night; there is no “bonus calorie happy hour” before bed.

    However…

    If we are eating late at night, that makes it difficult to breakfast in the morning (as is ideal) and still maintain a >16hr fasting window as is optimal, per:

    ❝the effects of the main forms of fasting, activating the metabolic switch from glucose to fat and ketones (G-to-K), starting 12-16 h after cessation or strong reduction of food intake

    ~ Dr. Françoise Wilhelmi de Toledo et al.

    Read in full: Unravelling the health effects of fasting: a long road from obesity treatment to healthy life span increase and improved cognition

    So in other words: since the benefits of intermittent fasting start at 12 hours into the fast, you’re not going to get them if you’re breakfasting at 10am and also eating in the evening.

    Summary:

    • It is best to eat breakfast around 10am, generally (ideally after some sunlight and exercise)
    • While there’s nothing wrong with eating in the evening per se, doing so means that a 10am breakfast will eliminate any fasting benefits you might otherwise get
    • If a “one meal a day, and that meal is breakfast” lifestyle doesn’t suit you, then one possible good compromise is to have a large breakfast, and then a smaller meal in the late afternoon / early evening.

    One last tip: the above is good, science-based information. Use it (or don’t), as you see fit. We’re not the boss of you:

    • Maybe you care most about getting the best circadian rhythm benefits, in which case, prioritizing breakfast being a) in the morning and b) the largest meal of the day, is key
    • Maybe you care most about getting the best intermittent fasting benefits, in which case, for many people’s lifestyle, a fine option is skipping eating in the morning, and having one meal in the late afternoon / early evening.

    Take care!

  • How to Eat 30 Plants a Week – by Hugh Fearnley-Whittingstall

    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.

    If you’re used to eating the same two fruits and three vegetables in rotation, the “gold standard” evidence-based advice to “eat 30 different plants per week” can seem a little daunting.

    Where this book excels is in reminding the reader to use a lot of diverse plants that are readily available in any well-stocked supermarket, but often get forgotten just because “we don’t buy that”, so it becomes invisible on the shelf.

    It’s not just a recipe book (though yes, there are plenty of recipes here); it’s also advice about stocking up and maintaining that stock, advice on reframing certain choices to inject a little diversity into every meal without it become onerous, meal-planning rotation advice, and a lot of recipes that are easy but plant-rich, for example “this soup that has these six plants in it”, etc.

    He also gives, for those eager to get started, “10 x 3 recipes per week to guarantee your 30”, in other words, 10 sets of 3 recipes, wherein each set of 3 recipes uses >30 different plants between them, such that if we have each of these set-of-three meals over the course of the week, then what we do in the other 4–18 meals (depending on how many meals per day you like to have) is all just a bonus.

    The latter is what makes this book an incredibly stress-free approach to more plant-diverse eating for life.

    Bottom line: if you want to be able to answer “do you get your five-a-day?” with “you mean breakfast?” because you’ve already hit five by breakfast each day, then this is the book for you.

  • Science of HIIT – by Ingrid Clay

    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 previously reviewed another book in this series, Science of Yoga. This one’s about HIIT: High Intensity Interval Training!

    We’ve written about HIIT before too, but our article doesn’t have the same amount of room as a book, so…

    This one lays out 90 key HIIT exercises that you can do at home without special equipment. By “without special equipment”, we mean: there are a few exercises that use dumbbells, but if you don’t want to get/use dumbbells, you can improvize (e.g. with water bottles as weights) or skip those. All the rest require just your body!

    The illustrations are clear and the explanations excellent. The book also dives into (as the title promises) the science of HIIT, and why it works the way it does to give results that can’t be achieved with other forms of exercise.

    Bottom line: if you’ve been wanting to do HIIT but have not yet found a way of doing it that suits your lifestyle, this book gives many excellent options.

    Click here to check out Science of HIIT, and level-up yours!

  • Hearty Healthy Ragù

    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.

    Ragù is a traditional Italian meaty sauce with tomato, and is the base for a number of other Italian dishes. It can be enjoyed as-is, or with very minor modifications can be turned into a Bolognese sauce or a lasagna filling or various other things. Our variations from tradition are mainly twofold here: we’re using nutrition-packed lentils instead of meat (but with a couple of twists that make them meatier), and we’re not using wine.

    Traditionally, red wine is used in a ragù (white wine if you want to make it into a Bolognese sauce, by the way), but with all we’re doing it’s not necessary. If you want to add a splash of wine, we’re not going to call that a healthy ingredient, but we’re also not the boss of you

    You will need

    • 1 large onion (or equivalent small ones), chopped roughly
    • 1 bulb garlic (or to your heart’s content), chopped finely or crushed
    • 4 large tomatoes, chopped (or 2 cans chopped tomatoes)
    • 1 tube (usually about 7 oz) tomato purée
    • 1 cup brown lentils (green lentils will do if you can’t get brown)
    • 1 tbsp chia seeds
    • 1 tbsp black pepper, cracked or coarse ground
    • 1 bunch fresh basil, finely chopped (or 1 tbsp, freeze-dried)
    • 1 bunch fresh oregano, finely chopped (or 1 tbsp, freeze-dried)
    • 1 tbsp nutritional yeast (failing that, 1 tbsp yeast extract, yes, even if you don’t like it, we promise it won’t taste like it once it’s done; it just makes the dish meatier in taste and also adds vitamin B12)
    • 1 tsp cumin, ground (note that this one was tsp, not tbsp like the others)
    • 1 tsp MSG, or 2 tsp low-sodium salt
    • 4 cups water
    • Olive oil for frying (ideally Extra Virgin, but so long as it’s at least marked virgin olive oil and not cut with other oils, that’s fine)
    • Parsley, chopped, to garnish

    Method

    (we suggest you read everything at least once before doing anything)

    1) Put the lentils in a small saucepan, or if you have one, a rice cooker (the rice cooker is better; works better and requires less attention), adding the chia seeds, MSG or low sodium salt, and nutritional yeast (or yeast extract). as well as the cumin. Add 4 cups boiling water and turn on the heat to cook them. This will probably take about 15–20 minutes; you want the lentils to be soft; a tiny bit past al dente, but not so far as mushy.

    2) Fry the onion in some olive oil in a big pan (everything is going in here eventually if the pan is big enough; if it isn’t, you’ll need to transfer to a bigger pan in a bit). Once they’re nearly done, throw in the garlic too. If the lentils aren’t done yet, take the onions and garlic off the heat while you wait. After a few times of doing this recipe, you’ll be doing everything like clockwork and it’ll all align perfectly.

    3) Drain the lentils (if all the water wasn’t absorbed; again, after doing it a few times, you’ll just use the right amount of water for your apparatus) but don’t rinse them (remember you put seasonings in here!), and add them to the pan with the onions and garlic; add a splash more olive oil if necessary, and stir until all the would-be-excess fat is absorbed into the lentils.

    Note: the excess fat to be absorbed by the lentils was a feature not a bug; we wanted a little fat in the lentils! Makes the dish meatier and tastier, as well as more nutrient-dense.

    4) add the tomatoes and tomato purée, stirring them in thoroughly; add the basil and oregano too and stir those in as well. Set it on a low heat for at least 10–15 minutes, stirring occasionally to let the flavors blend.

    (if you happen to be serving pasta with it, then the time it takes to boil water and cook the pasta is a good time for the flavors to do their thing)

    5) take it off the heat, and add the parsley garnish. It’s done!

    Enjoy!
