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!

  • Dr. Greger’s Daily Dozen

    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.

    Give Us This Day Our Daily Dozen

    This is Dr. Michael Greger. He’s a physician-turned-author-educator, and we’ve featured him and his work occasionally over the past year or so:

    But what we’ve not covered, astonishingly, is one of the things for which he’s most famous, which is…

    Dr. Greger’s Daily Dozen

    Based on the research in the very information-dense tome that his his magnum opus How Not To Die (while it doesn’t confer immortality, it does help avoid the most common causes of death), Dr. Greger recommends that we take care to enjoy each of the following things per day:

    Beans

    • Servings: 3 per day
    • Examples: ½ cup cooked beans, ¼ cup hummus

    Greens

    • Servings: 2 per day
    • Examples: 1 cup raw, ½ cup cooked

    Cruciferous vegetables

    • Servings: 1 per day
    • Examples: ½ cup chopped, 1 tablespoon horseradish

    Other vegetables

    • Servings: 2 per day
    • Examples: ½ cup non-leafy vegetables

    Whole grains

    • Servings: 3 per day
    • Examples: ½ cup hot cereal, 1 slice of bread

    Berries

    • Servings: 1 per day
    • Examples: ½ cup fresh or frozen, ¼ cup dried

    Other fruits

    • Servings: 3 per day
    • Examples: 1 medium fruit, ¼ cup dried fruit

    Flaxseed

    • Servings: 1 per day
    • Examples: 1 tablespoon ground

    Nuts & (other) seeds

    • Servings: 1 per day
    • Examples: ¼ cup nuts, 2 tablespoons nut butter

    Herbs & spices

    • Servings: 1 per day
    • Examples: ¼ teaspoon turmeric

    Hydrating drinks

    • Servings: 60 oz per day
    • Examples: Water, green tea, hibiscus tea

    Exercise

    • Servings: Once per day
    • Examples: 90 minutes moderate or 40 minutes vigorous

    Superficially it seems an interesting choice to, after listing 11 foods and drinks, have the 12th item as exercise but not add a 13th one of sleep—but perhaps he quite reasonably expects that people get a dose of sleep with more consistency than people get a dose of exercise. After all, exercise is mostly optional, whereas if we try to skip sleep for too long, our body will force the matter for us.

  • Broccoli vs Red Cabbage – 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 broccoli to red cabbage, we picked the broccoli.

    Why?

    Both are certainly great! Which is usual for any Brassica oleracea cultivar (as both of these vegetables are). But there is a clear winner:

    In terms of macros, broccoli has more fiber and protein, while red cabbage has more carbs. Now, nobody is getting metabolic disease from eating cabbage, but by the numbers, this is a simple win for broccoli, especially on account of the fiber.

    In the category of vitamins, broccoli has more of vitamins B1, B2, B3, B5, C, E, K, and choline, while red cabbage has more of vitamins A and B6. Another win for broccoli.

    When it comes to minerals, it’s a similar story: broccoli has more copper, magnesium, phosphorus, potassium, selenium, and zinc, while red cabbage has more iron and manganese. They’re equal in calcium, by the way. Broccoli wins again.

    Looking at polyphenols, both cultivars have plenty, but broccoli has more in total, as well as more variety, so yet another win for broccoli here.

    Now, standing next to broccoli has made red cabbage look bad, but we want to assure you that red cabbage is itself a nutritional powerhouse—broccoli is just even more so.

    So of course, by all means do enjoy either or both; 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

    ❝I think the heart may be an issue for lots of us. I know it is for me due to AFib. When I’m in my training zone like on a treadmill, I’m usually around 110 to 120. But there are occasionally times when I’m at 140 or 150. How dangerous is that? If I use that formula of 180 minus age, thats 103. I get nothing from that. My resting heart rate is in the 50 to 60 range.❞

    First, for safety, let us draw attention to our medical disclaimer at the bottom of each email, and also specifically note that we are not cardiologists here, let alone your cardiologist. There’s a lot we can’t know or advise about. However, as general rules of thumb:

    For people without serious health conditions, it is considered good and healthful for one’s heart rate to double (from its resting rate) during exercise, with even more than 2.5x resting rate being nothing more than a good cardio workout.

    As for “180 minus age” (presuming you mean: to calculate the safe maximum heart rate), more common (and used by the American Heart Association) is 220 minus age. In your case, that’d give 143.

    Having atrial fibrillation may change this however, and we can’t offer medical advice.

    We can point to this AHA “AFib Resources For Patients and Professionals”, including this handy FAQ sheet which says:

    “Am I able to exercise?” / “Yes, as long as you’re cleared by your doctor, you can perform normal activities of daily living that you can tolerate” (accompanied by a little graphic of a person using an exercise bike)

    You personally probably know this already, of course, but it’s quite an extensive collection of resources, so we thought we’d include it.

    It’s certainly a good idea for everyone to be aware of their healthy heart rate ranges, regardless of having a known heart condition or not, though!

    ❝I would like to see some articles on osteoporosis❞

    You might enjoy this mythbusting main feature we did a few weeks ago!

    The Bare-Bones Truth About Osteoporosis

    ❝Interesting, but… Did you know spinach is high in oxylates? Some people are sensitive and can cause increased inflammation, joint pain or even kidney stones. Moderation is key. My sister and I like to eat healthy but found out by experience that too much spinach salad caused us joint and other aches.❞

    It’s certainly good to be mindful of such things! For most people, a daily serving of spinach shouldn’t cause ill effects, and certainly there are other greens to eat.

    We wondered whether there was a way to reduce the oxalate content, and we found:

    How to Reduce Oxalic Acid in Spinach: Neutralizing Oxalates

    …which led us this product on Amazon:

    Nephure Oxalate Reducing Enzyme, Low Oxalate Diet Support

    We wondered what “nephure” was, and whether it could be trusted, and came across this “Supplement Police” article about it:

    Nephure Review – Oxalate Reducing Enzyme Powder Health Benefits?

    …which honestly, seems to have been written as a paid advertisement. But! It did reference a study, which we were able to look up, and find:

    In vitro and in vivo safety evaluation of Nephure™

    …which seems to indicate that it was safe (for rats) in all the ways that they checked. They did not, however, check whether it actually reduced oxalate content in spinach or any other food.

    The authors did declare a conflict of interest, in that they had a financial relationship with the sponsor of the study, Captozyme Inc.

    All in all, it may be better to just have kale instead of spinach:

    Hampton at Hybrid Calisthenics always has very sound advice in his uplifting videos, and this one’s no exception:

    Key tips for optimizing workouts without burning out

    “We all have the same 24 hours” is a folly when in fact, some of us have more responsibilities and/or other impediments to getting things done (e.g. disabilities).

    A quick word on disabilities first: sometimes people are quick to point out Paralympian athletes, and “if they can do it, so can you!” and forget that these people are in the top percentile of the top percentile of the top percentile of human performance. If you wouldn’t disparagingly say “if Simone Biles/Hussein Bolt/Michael Phelps can do it, so can you”, then don’t for Paralympians either 😉

    Now, as for Hampton’s advice, he recommends:

    Enjoy short, intense workouts:

    • You can get effective results in under 30 minutes (or even just a few minutes per day) with compound exercises (e.g., squats, pull-ups).
    • Focus on full-body movements also saves time!
    • Push closer to failure when possible to maximize efficiency. It’s the last rep where most of the strength gains are made! Same deal with cardiovascular fitness, too. Nevertheless, do take safety into account in both cases, of course.

    Time your rest periods:

    • Resting for 2–3 minutes between sets ensures optimal recovery.
    • Avoid getting distracted during rest by setting a timer to stay focused.
    • 10almonds tip: use this time to practice a mindfulness meditation. That will greatly reduce the chance of you becoming distracted.

    Remember holistic fitness:

    • Fitness isn’t just about exercise; diet, sleep, and stress management are equally important for your fitness as much as for the rest of your health.
    • Better sleep and reduced stress will help you exercise more consistently and avoid junk food.

    Address burnout:

    • If feeling too exhausted to apply these tips, focus on getting better rest and reducing stress first.
    • Taking a short break to reset can help in the long run.

  • How Primary Care Is Being Disrupted: A Video Primer

    How patients are seeing their doctor is changing, and that could shape access to and quality of care for decades to come.

    More than 100 million Americans don’t have regular access to primary care, a number that has nearly doubled since 2014. Yet demand for primary care is up, spurred partly by record enrollment in Affordable Care Act plans. Under pressure from increased demand, consolidation, and changing patient expectations, the model of care no longer means visiting the same doctor for decades.

    KFF Health News senior correspondent Julie Appleby breaks down what is happening — and what it means for patients.

    Known as the “front door” to the health system, primary care is changing. Under pressure from increased demand, consolidation, and changing patient expectations, the model of care no longer means visiting the same doctor for decades. KFF Health News looks at what this means for patients.

  • Egg Noodles vs Rice Noodles – 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 egg noodles to rice noodles, we picked the egg noodles.

    Why?

    It was close—these are both quite mediocre foods. They’re neither amazing for the health nor appalling for the health (in moderation). They are both relatively low in nutrients, but they are also low in anti-nutrients, i.e. things that have a negative effect on the health.

    Their mineral profiles are similar; both are a source of selenium, manganese, phosphorus, copper, and iron. Not as good as many sources, but not devoid of nutrients either.

    Their vitamin profiles are both pitiful; rice noodles have trace amounts of various vitamins, and egg noodles have only slightly more. While eggs themselves are nutritious, the processing has robbed them of much of their value.

    In terms of macros, egg noodles have a little more fat (but the fats are healthier) and rice noodles have a lot more carbs, so this is the main differentiator, and is the main reason we chose the egg noodles over the rice noodles. Both have a comparable (small) amount of protein.

    In short:

    • They’re comparable on minerals, and vitamins here are barely worth speaking about (though egg noodles do have marginally more)
    • Egg noodles have a little more fat (but the fats are healthier)
    • Rice noodles have a lot more carbs (with a moderately high glycemic index, which is relatively worse—if you eat them with vegetables and fats, then that’ll offset this, but we’re judging the two items on merit, not your meal)
