The Fiber Of Good Health

We’ve written before about how most people in industrialized nations in general, and N. America in particular, do not get nearly enough fiber:

Why You’re Probably Not Getting Enough Fiber (And How To Fix It)

Fiber’s important for many aspects of health, not least of all the heart:

What Matters Most For Your Heart? Eat More (Of This) For Lower Blood Pressure

As well, of course, as being critical for gut health:

Gut Health 101: Making Friends With Your Gut (You Can Thank Us Later)

But is all fiber “prebiotic fiber”, and/or are some better than others?

Beta-glucan

A recent study (it’s a mouse study, but promising in its applicability for humans) examined the health impacts of 5 different fiber types:

  • pectin
  • β-glucan
  • wheat dextrin
  • resistant starch
  • cellulose (control)

As for health metrics, they measured:

  • body weight
  • adiposity
  • indirect calorimetry
  • glucose tolerance
  • gut microbiota
  • metabolites thereof

What they found was…

❝Only β-glucan supplementation during HFD-feeding decreased adiposity and body weight gain and improved glucose tolerance compared with HFD-cellulose, whereas all other fibers had no effect. This was associated with increased energy expenditure and locomotor activity in mice compared with HFD-cellulose.

All fibers supplemented into an HFD uniquely shifted the intestinal microbiota and cecal short-chain fatty acids; however, only β-glucan supplementation increased cecal butyrate concentrations. Lastly, all fibers altered the small-intestinal microbiota and portal bile acid composition. ❞

~ Dr. Elizabeth Howard et al.

If you’d like to read less, the short version is that they are all good but β-glucan scored best in several metrics.

It also acts indirectly as a GLP-1 agonist, by the way:

The right fiber may help you lose weight

You may be wondering: what is β-glucan found in?

It’s found in many (non-animal product) foods, but oats, barley, mushrooms, and yeasts are all good sources.

Is it available as a supplement?

More or less; there are supplements that contain it generously, here’s an example product on Amazon, a cordyceps extract, of which >30% is β-glucan.

As an aside, cordyceps itself has many other healthful properties too:

  • The Keys to Good Mental Wellbeing

    The Nine Keys To Good Mental Wellbeing

    Today’s main feature is a bit “pop psychology”, but it has its underpinnings in actual psychology, and is especially useful if approached from that angle.

    What it’s most popularly enjoyed as:

    • A personality-typing system.
    • People love little quizzes and identifiers and such.

    What it’s actually really useful as:

    • A tool for understanding why people (including ourselves) are the way we are
    • A foundational knowledge for living better ourselves, and helping others too

    This stems from the fairly simple principle, uncontroversial in psychology:

    • We have needs, desires, and aversions
    • We act in a way that tries to get our needs met and avoid suffering
    • Thus: Need/Fear → Motivation → Action

    The Enneagram

    The Enneagram (ἐννέα = “nine” in Ancient Greek) system posits that we each have one fundamental need/fear (from a list of nine) that’s strongest for us. A deep-seated insecurity/longing, that we’ll go to almost any lengths to try to meet. Sometimes, in good ways, sometimes, bad.

    The Nine Basic Fears/Insecurities, And Their Corresponding Needs/Desires:

    1. Fear of being a fundamentally bad, wrong person / Need to be good and correct
    2. Fear of being fundamentally unloveable / Need to be loved
    3. Fear of being fundamentally worthless / Need to be valued
    4. Fear of being like everyone else / Need to be different
    5. Fear of being useless / Need to be useful
    6. Fear of being outcast / Need to have a set place in the group
    7. Fear of missing out / Need to experience things
    8. Fear of being hurt or controlled / Need to be in control
    9. Fear of conflict / Need to be at peace

    Of course, most of us have most of these fears/needs to some extent, though usually one will stand out—especially if we aren’t managing it well. The less healthy our coping mechanisms, the more obvious it is how we’re trying to overcompensate in some fashion. For example:

    1. A person who fears being wrong and so becomes a perfectionist rules-abider to a fault
    2. A person who fears being unloveable, and so exaggerates problems to get pity, as the next best thing
    3. A person who fears being worthless, and so exaggerates their accomplishments in order to be admired and valued
    4. A person who fears being like everyone else, and so descends into a “nobody could ever possibly understand me” black hole of pathos.
    5. A person who fears being useless, so burns themself out trying to be an omnicompetent Leonardo da Vinci without ever actually taking the time to stop and smell the flowers as Leonardo did.
    6. A person who fears being outcast, so becomes clingy, passive-aggressive, and suspicious
    7. A person who fears missing out, so tries to experience all the things all the time, ruining their health with dizzying highs and crushing lows.
    8. A person who fears being hurt or controlled, so becomes aggressive and domineering
    9. A person who fears conflict, so shuts down at the slightest hint of it

    If we have healthier coping mechanisms, these same nine people can look a lot different, but in much more subtle ways because we’re not trying to overcompensate so badly:

    1. A person who lives their life rationally by principles that can be adapted as they learn
    2. A person who loves and is loved, as perhaps the most notable part of their character
    3. A person who sets reasonable goals and accomplishes them, and seeks to uplift others
    4. A person who creates and innovates, enriching their own life and the lives of others
    5. A person who is simply very competent and knowledgeable, without overstretching
    6. A person who is dependable and loyal, and a reliable part of something bigger than themself
    7. A person who is fun to be around and loves trying new things, while also knowing how to relax
    8. A person who develops their leadership skills and is a tower of strength for others
    9. A person who knows how to make peace and does so—by themself, and with others

    By being aware of our own fears/insecurities that may drive our motivations and thus underpin our behaviors, we can usually manage them in a much more mindful fashion. Same goes when it comes to managing interactions with other people, too:

    • Letting the Type 3 know you value them, not their accomplishments or what they can do for you.
    • Appreciating the Type 5’s (varied or specialist) skills and knowledge.
    • Giving love to a Type 2 unprompted, but on your own terms, with your own boundaries.
    • And so on for other types

    Or for yourself…

    • As a Type 8, remembering that you can let go sometimes and let someone else be in charge.
    • As a Type 1, catching yourself holding yourself (or others) to impossible standards, and then easing up on that a little.
    • As a Type 9, remembering to stand up for yourself and others, however gently, but firmly.
    • And so on for other types

    If you’re unsure what to focus on, ask yourself: what’s your worst nightmare or greatest daydream? Then work out what it is about that, that makes it feel so bad or good.

    Then, approach things mindfully. Catch yourself in your unhealthy coping mechanisms, and find healthy ones instead.

    What if I get my type wrong? Or I get someone else’s type wrong?

    Obviously it’s better to get them right for maximum effect, but you can never go too far wrong anyway… because we all have all nine of those qualities in us, it’s just a matter of how strong a factor each is for us. So in the worst case scenario, you’ll make someone feel more secure about something that was only a very minor insecurity for them, for example.

    Or in the case of your own type, you may mistakenly think you’re acing being the world’s healthiest Type 5, until you realize you’re actually a Type 3 who thought learning all those things would make you more worthy (spoiler: those things are great, but you’re worthy already). Again, not the end of the world! No matter what, you’re learning and growing, and that’s good.

    We’d love to offer a quick free test here, but all the tests we could find either require paid registration or are wildly inaccurate, so we’ll not waste your time.

    However, we do also think that working it out for yourself is better, as it means you have a handle on what those ideas, fears, insecurities, desires, needs, really mean to you—that way you can actually use the information!

    We’ll close by repeating our previous advice: If you’re unsure what to focus on, ask yourself: what’s your worst nightmare or greatest daydream? Then work out what it is about those scenarios that make them so bad or good. That’ll help you find your real fears/needs, such that you can work on them.

    Good luck!

  • Sleep wrinkles are real. Here’s how they leave their mark

    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 wake up, stagger to the bathroom and gaze into the mirror. No, you’re not imagining it. You’ve developed face wrinkles overnight. They’re sleep wrinkles.

    Sleep wrinkles are temporary. But as your skin loses its elasticity as you age, they can set in.

    Here’s what you can do to minimise the chance of them forming in the first place.

    How side-sleeping affects your face

    Your skin wrinkles for a number of reasons, including ageing, sun damage, smoking, poor hydration, habitual facial expressions (such as grinning, pouting, frowning, squinting) and sleeping positions.

    When you sleep on your side or stomach, your face skin is squeezed and crushed a lot more than if you sleep on your back. When you sleep on your side or stomach, gravity presses your face against the pillow. Your face skin is distorted as your skin is stretched, compressed and pulled in all directions as you move about in your sleep.

    You can reduce these external forces acting on the face by sleeping on your back or changing positions frequently.

    Doctors can tell which side you sleep on by looking at your face

    In a young face, sleep wrinkles are transient and disappear after waking.

    Temporary sleep wrinkles can become persistent with time and repetition. As we age, our skin loses elasticity (recoil) and extensibility (stretch), creating ideal conditions for sleep wrinkles or lines to set in and last longer.

    The time spent in each sleeping position, the magnitude of external forces applied to each area of the face, as well as the surface area of contact with the pillow surface, also affects the pattern and rate of sleep wrinkle formation.

    Skin specialists can often recognise this. People who favour sleeping on one side of their body tend to have a flatter face on their sleeping side and more visible sleep lines.

    Can a night skincare routine avoid sleep wrinkles?

    Collagen and elastin are two primary components of the dermis (inner layer) of skin. They form the skin structure and maintain the elasticity of skin.

    Supplementing collagen through skincare routines to enhance skin elasticity can help reduce wrinkle formation.

    Hyaluronic acid is a naturally occurring molecule in human bodies. It holds our skin’s collagen and elastin in a proper configuration, stimulates the production of collagen and adds hydration, which can help slow down wrinkle formation. Hyaluronic acid is one of the most common active ingredients in skincare creams, gels and lotions.

    Moisturisers can hydrate the skin in different ways. “Occlusive” substances produce a thin layer of oil on the skin that prevents water loss due to evaporation. “Humectants” attract and hold water in the skin, and they can differ in their capacity to bind with water, which influences the degree of skin hydration.

    Do silk pillowcases actually make a difference?

    Can they help? New Africa/Shutterstock

    Silk pillowcases can make a difference in wrinkle formation, if they let your skin glide and move, rather than adding friction and pressure on a single spot. If you can, use silk sheets and silk pillows.

    Studies have also shown pillows designed to reduce mechanical stress during sleep can prevent skin deformations. Such a pillow could be useful in slowing down and preventing the formation of certain facial wrinkles.

    Sleeping on your back can reduce the risk of sleep lines, as can a nighttime routine of moisturising before sleep.

    Otherwise, lifestyle choices and habits, such quitting smoking, drinking plenty of water, a healthy diet (eating enough vegetables, fruits, nuts, seeds, healthy fats, yogurt and other fermented foods) and regular use of sunscreens can help improve the appearance of the skin on our face.

  • Getting Flexible, Starting As An Adult: How Long Does It Really Take?

    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.

    Aleks Brzezinska didn’t start stretching until she was 21, and here’s what she found:

    We’ll not stretch the truth

    A lot of stretching programs will claim “do the splits in 30 days” or similar, and while this may occasionally be true, usually it’ll take longer.

    Brzezinska started stretching seriously when she was 21, and made significant flexibility gains between the ages of 21 and 23 with consistent practice. Since then, she’s just maintained her flexibility.

    There are facts that affect progress significantly, such as:

    • Anatomy: body structure, age, and joint flexibility do influence flexibility; starting younger and/or having hypermobile joints does make it easier.
    • Consistency: regular practice (2–3 times a week) is crucial, but avoid overdoing it, especially when sore.
    • Lifestyle: weightlifting, running, and similar activities can tighten muscles, making flexibility harder to achieve.
    • Hydration: staying hydrated is important for muscle flexibility.

    She also recommends incorporating a variety of different stretching types, rather than just one method, for example passive stretching, active stretching, Proprioceptive Neuromuscular Facilitation (PNF) stretching, and mobility work.

  • When A Period Is Very Late (Post-Menopause)
  • Play Bold – by Magnus Penker

    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.

    This book is very different to what you might expect, from the title.

    We often see: “play bold, believe in yourself, the universe rewards action” etc… Instead, this one is more: “play bold, pay attention to the data, use these metrics, learn from what these businesses did and what their results were”, etc.

    We often see: “here’s an anecdote about a historical figure and/or celebrity who made a tremendous bluff and it worked out well so you should too” etc… Instead, this one is more: “see how what we think of as safety is actually anything but! And how by embracing change quickly (or ideally: proactively), we can stay ahead of disaster that may otherwise hit us”.

    Penker’s background is also relevant here. He has decades of experience, having “launched 10 start-ups and acquired, turned around, and sold over 30 SMEs all over Europe”. Importantly, he’s also “still in the game”… So, unlike many authors whose last experience in the industry was in the 1970s and who wonder why people aren’t reaping the same rewards today!

    Penker is the therefore opposite of many who advocate to “play bold” but simply mean “fail fast, fail often”… While quietly relying on their family’s capital and privilege to leave a trail of financial destruction behind them, and simultaneously gloating about their imagined business expertise.

    In short: boldness does not equate to foolhardiness, and foolhardiness does not equate to boldness.

    As for telling the difference? Well, for that we recommend reading the book—It’s a highly instructive one.

    So, no question/request too big or small

    Side effects of statins, are they worth it? Depression, are antidepressants worth it?

    About statins, that depends a lot on you, your circumstances, and—as it happens—your gender. We covered this in a main feature recently, but a short answer is: for most people, they may not be the best first choice, and could even make things worse. For some people, however, they really are just what’s needed.

    • Factors that make them more likely better for you: being a man, or having atherosclerosis
    • Factors that make them more likely worse for you: being a woman in general

    Check out the main feature we did: Statins: His & Hers?

    As for antidepressants? That depends a lot on you, your physiology, your depression, your circumstances, and more. We’ll definitely do a main feature on that sometime soon, as there’s a lot that most people don’t know!

  • It’s Not Hysteria – by Dr. Karen Tan

    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.

    Firstly, who this book is aimed at: in case it wasn’t clear, this book assumes you have, or at least have had, a uterus. If that’s not you, then well, it’ll still be an interesting read but it won’t be about your reproductive health.

    Secondly, about that “reproductive health”: it’s mostly not actually about reproductive health literally, but rather, the health of one’s reproductive organs and the things that they affect—which is a lot more than the ability to reproduce!

    Dr. Tang takes us on a (respectably in-depth) tour of the relevant anatomy, before moving on to physiology, before continuing to pathology (i.e. things that can go wrong, and often do), and finally various treatment options, including elective procedures, and the pros and cons thereof.

    She also talks the reader through talking about things with gynecologists and other healthcare providers, and making sure concerns are not dismissed out-of-hand (something that happens a lot, of course).

    The style throughout is quite detailed prose, but without being difficult at all to read, and (assuming one is interested in the topic) it’s very engaging.

    Bottom line: if you would like to know more about uteri and everything that is (or commonly/unfortunately) can be attached to them, the effects they have on the rest of the body and health, and what can be done about things not being quite right, then this is a good book for that.
