The Diet Myth – by Dr. Tim Spector

Why are we supposed to go low-carb, but get plenty of whole grains? Avoid saturated fat, but olive oil is one of the healthiest fats around? Will cheese kill us or save us? Even amongst the well-informed, there’s a lot of confusion. This book addresses these and many such topics.

A main theme of the book is howa lot of it relates to the state of our gut microbiome, and what is good or bad for that. He also discusses, for example, how microbes predict obesity better than genes, and the good news is: we can change our microbes a lot more easily than we can change our genes!

In the category of criticism, he repeats some decades-old bad science in some areas outside of his field (i.e. unrelated to nutrition), so that’s unfortunate, and/but doesn’t detract from the value of the book if we keep to the main topic.

Bottom line: if you’d like to understand better the physiology and microbiology behind why dieting does work for most people (and how to do it better), then this is a great book for that.

  • Do You Know These 10 Common Ovarian Cancer Symptoms?

    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 better to know in advance:

    Things you may need to know

    The symptoms listed in the video are:

    1. Abdominal bloating: persistent bloating due to fluid buildup, often mistaken for overeating or weight gain.
    2. Pelvic or abdominal pain: continuous pain in the lower abdomen or pelvis, unrelated to menstruation.
    3. Difficulty eating or feeling full quickly: loss of appetite or feeling full after eating only a small amount.
    4. Urgent or frequent urination: increased need to urinate due to tumor pressure on the bladder.
    5. Unexplained weight loss: sudden weight loss without changes in diet or exercise (this goes for cancer in general, of course).
    6. Fatigue: extreme tiredness that doesn’t improve with rest, possibly linked to anemia.
    7. Back pain: persistent lower back pain due to tumor pressure or fluid buildup.
    8. Changes in bowel habits: unexplained constipation, diarrhea, or a feeling of incomplete bowel movements.
    9. Menstrual changes: irregular, heavier, lighter, or missed periods in premenopausal women.
    10. Pain during intercourse: discomfort or deep pelvic pain during or after vaginal sex—often overlooked!

    Of course, some of those things can be caused by many things, but it’s worth getting it checked out, especially if you have a cluster of them together. Even if it’s not ovarian cancer (and hopefully it won’t be), having multiple things from this list certainly means that “something wrong is not right” in any case.

  • Body Image Dissatisfaction/Appreciation Across The Ages

    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.

    Every second news article about body image issues is talking about teens and social media use, but science tells a different story.

    A large (n=1,327) study of people of mixed genders aged 16–88 examined matters relating to people’s body image, expecting…

    ❝We hypothesized that body dissatisfaction and importance of appearance would be higher in women than in men, that body dissatisfaction would remain stable across age in women, and that importance of appearance would be lower in older women compared to younger women. Body appreciation was predicted to be higher in men than in women.❞

    As they discovered, only half of that turned out to be true:

    ❝In line with our hypotheses, body dissatisfaction was higher in women than in men and was unaffected by age in women, and importance of appearance was higher in women than in men.

    However, only in men did age predict a lower level of the importance of appearance. Compared to men, women stated that they would invest more hours of their lives to achieve their ideal appearance.

    Contrary to our assumption, body appreciation improved and was higher in women across all ages than in men.❞

    You can read the study in full here:

    Body Dissatisfaction, Importance of Appearance, and Body Appreciation in Men and Women Over the Lifespan

    That’s a lot of information, and we don’t have the space to go into all parts of it here, fascinating as that would be. So we’re going to put two pieces of information (from the above) next to each other:

    • body dissatisfaction was higher in women than in men and was unaffected by age in women
    • body appreciation improved and was higher in women across all ages than in men

    …and resolve this apparent paradox.

    Dissatisfied appreciation

    How is it that women are both more dissatisfied with, and yet also more appreciative of, their bodies?

    The answer is that we can have positive and negative feelings about the same thing, without them cancelling each other out. In short, simply, feeling more feelings about it.

    Whether the gender-related disparity in this case comes more from hormones or society could be vigorously debated, but chances are, it’s both. And, for our gentleman-readers, note that the principle still applies to you, even if scaled down on average.

    Call to action:

    • be aware of the negative feelings of body dissatisfaction
    • focus on the positive feelings of body appreciation

    While in theory both could motivate us to action, in reality, the former will tend to inform us (about what we might wish to change), while the latter will actually motivate us in a useful way (to do something positive about it).

    This is because the negative feelings about body image tend to be largely based in shame, and shame is a useless motivator (i.e., it simply doesn’t work) when it comes to taking positive actions:

    Why Shame Only Works Negatively

    You can’t hate yourself into a body you love

    That may sound like a wishy-washy platitude, but given the evidence on how shame works (and doesn’t), it’s true.

    Instead, once you’ve identified the things about your body with which you’re dissatisfied, you can then assess:

    • what can reasonably be changed
    • whether it is important enough to you to change it
    • how to go about usefully changing it

    While weight issues are perhaps the most commonly-discussed body image consideration, to the point that often all others get forgotten, let’s look at something that’s generally more specific to adults, and also a very common cause of distress for women and men alike: hair loss/thinning.

    If your hair is just starting to thin and fall, then if this bothers you, there’s a lot that can be done about it quite easily, but (and this is important) you have to love yourself enough to actually do it. Merely feeling miserable about it, and perhaps like you don’t deserve better, or that it is somehow a personal failing on your part, will not help.

    If your hair has been gone for years, then chances are you’ve made your peace with this by now, and might not even take it back if a fairy godmother came along and offered to restore it magically. On the other hand, let’s say that you’re just coming out the other end of a 10-year-long depression, and perhaps you let a lot of things go that you now wish you hadn’t, and maybe your hair is one of them. In this case, now you need to decide whether getting implants (likely the only solution at this late stage) is worth it.

    Note that in both cases, whatever the starting point and whether the path ahead is easy or hard, the person who has dissatisfaction and/but still values themself and their body will get what they need.

    In contrast, the person who has dissatisfaction and does not value themself and their body, will languish.

    The person without dissatisfaction, of course, probably already has what they need.

    In short: identification of dissatisfaction + love and appreciation of oneself and one’s body → motivation to usefully take action (out of love, not hate)

    Now, dear reader, apply the same thinking to whatever body image issues you may have, and take it from there!

    Embodiment

    A quick note in closing: if you are a person with no body dissatisfactions, there are two main possible reasons:

    • You are genuinely happy with your body in all respects. Congratulations!
    • You have disassociated from your body to such an extent that it’s become a mere vehicle to you and you don’t care about it.

    This latter may seem like a Zen-level win, but in fact it’s a warning sign for depression, so please do examine that even if you don’t “feel” depressed (depression is often characterized by a lack of feelings), perhaps by taking the (very quick) free PHQ9 Test ← under 2 minutes; immediate results; industry-standard diagnostic tool

    Take care!

    Inositol Does-It-Ol’!

    First things first, a quick clarification up-front:

    Myo-inositol or D-chiro-inositol?

    We’re going to be talking about inositol today, which comes in numerous forms, but most importantly:

    • Myo-inositol (myo-Ins)
    • D-chiro-inositol (D-chiro-Ins)

    These are both inositol, (a sugar alcohol!) and for our purposes today, the most relevant form is myo-inositol.

    The studies we’ll look at today are either:

    • just about myo-inositol, or
    • about myo-inositol in the presence of d-chiro-inositol at a 40:1 ratio.

    You have both in your body naturally; wherever supplementation is mentioned, it means supplementing with either:

    • extra myo-inositol (because that’s the one the body more often needs more of), or
    • both, at the 40:1 ratio that we mentioned above (because that’s one way to help balance an imbalanced ratio)

    With that in mind…

    Inositol against diabetes?

    Inositol is known to:

    • decrease insulin resistance
    • increase insulin sensitivity
    • have an important role in cell signaling
    • have an important role in metabolism

    The first two things there both mean that inositol is good against diabetes. It’s not “take this and you’re cured”, but:

    • if you’re pre-diabetic it may help you avoid type 2 diabetes
    • if you are diabetic (either type) it can help in the management of your diabetes.

    It does this by allowing your body to make better use of insulin (regardless of whether that insulin is from your pancreas or from the pharmacy).

    How does it do that? Research is still underway and there’s a lot we don’t know yet, but here’s one way, for example:

    ❝Evidence showed that inositol phosphates might enhance the browning of white adipocytes and directly improve insulin sensitivity through adipocytes❞

    Read: Role of Inositols and Inositol Phosphates in Energy Metabolism

    We mentioned its role in metabolism in a bullet-point above, and we didn’t just mean insulin sensitivity! There’s also…

    Inositol for thyroid function?

    The thyroid is one of the largest endocrine glands in the body, and it controls how quickly the body burns energy, makes proteins, and how sensitive the body should be to other hormones. So, it working correctly or not can have a big impact on everything from your mood to your weight to your energy levels.

    How does inositol affect thyroid function?

    • Inositol has an important role in thyroid function and dealing with autoimmune diseases.
    • Inositol is essential to produce H2O2 (yes, really) required for the synthesis of thyroid hormones.
    • Depletion of inositol may lead to the development of some thyroid diseases, such as hypothyroidism.
    • Inositol supplementation seems to help in the management of thyroid diseases.

    Inositol for PCOS?

    A systematic review published in the Journal of Gynecological Endocrinology noted:

    • Inositol can restore spontaneous ovarian activity (and consequently fertility) in most patients with PCOS.
    • Myo-inositol is a safe and effective treatment to improve:
      • ovarian function
      • healthy metabolism
      • healthy hormonal balance

    While very comprehensive (which is why we included it here), that review’s a little old, so…

    Check out this cutting edge (Jan 2023) study whose title says it all:

    Inositol is an effective and safe treatment in polycystic ovary syndrome: a systematic review and meta-analysis of randomized controlled trials

    Inositol for fertility?

    Just last year, Mendoza et al published that inositol supplementation, together with antioxidants, vitamins, and minerals, could be an optimal strategy to improve female fertility.

    This built from Gambiole and Forte’s work, which laid out how inositol is a safe compound for many issues related to fertility and pregnancy. In particular, several clinical trials demonstrated that:

    • inositol can have therapeutic effects in infertile women
    • inositol can also be useful as a preventive treatment during pregnancy
    • inositol could prevent the onset of neural tube defects
    • inositol also reduces the occurrence of gestational diabetes

    Due to the safety and efficiency of inositol, it can take the place of many drugs that are contraindicated in pregnancy. Basically: take this, and you’ll need fewer other drugs. Always a win!

    Inositol For Weight Loss

    We promised you “this alcohol sugar can reduce your BMI”, and we weren’t making it up!

    Zarezadeh et al conducited a very extensive systematic review, and found:

    • Oral inositol supplementation has positive effect on BMI reduction.
    • Inositol in the form of myo-inositol had the strongest effect on BMI reduction.
    • Participants with PCOS and/or who were overweight, experienced the most significant improvement of all.

    Want some inositol?

    As ever, we don’t sell it (or anything else), but for your convenience, here’s myo-inositol and d-chiro-inositol at a 40:1 ratio, available on Amazon!

  • The Evidence-Based Skincare That Beats Product-Specific Hype

    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 million videos on YouTube will try to sell you a 17-step skincare routine, or a 1-ingredient magical fix that’s messy and inconvenient enough you’ll do it once and then discard it. This one takes a simple, scientific approach instead.

    The Basics That Count

    Ali Abdaal, known for his productivity hacks channel, enlisted the help of his friend, dermatologist Dr. Usama Syed, who recommends the following 3–4 things:

    1. Moisturize twice per day. Skin acts as a barrier, locking in moisture and protecting against irritants. Moisturizers replenish fats and proteins, maintaining this barrier and preventing dry, inflamed, and itchy skin. He uses CeraVe, but if you have one you know works well with your skin, stick with that, because skin comes in many varieties and yours might not be like his.
    2. Use sunscreen every day. Your phone’s weather app should comment on your local UV index. If it’s “moderate” or above, then sunscreen is a must—even if you aren’t someone who burns easily at all, the critical thing here is avoiding UV radiation causing DNA mutations in skin cells, leading to wrinkles, dark spots, and potentially skin cancer. Use a broad-spectrum sunscreen, ideally SPF 50.
    3. Use a retinoid. Retinoids are vitamin A-based and offer anti-aging benefits by promoting collagen growth, reducing pigmentation, and accelerating skin cell regeneration. Retinols are weaker, over-the-counter options, while stronger retinoids may require a prescription. Start gently with low dosage, whatever you choose, as initially they can cause dryness or sensitivity, before making everything better. He recommends adapalene as a starter retinoid (such as Differen gel, to give an example brand name).
    4. Optional: use a cleanser. Cleansers remove oils and dirt that water alone can’t. He recommends using a hydrating cleanser, to avoid stripping natural healthy oils as well as unwanted ones. That said, a cleanser is probably only beneficial if your skin tends towards the oily end of the dry-to-oily spectrum.

  • 10 “Healthy” Foods That Are Often Worse Than You Think

    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 is healthy, it’s a…” is an easy mistake to make if one doesn’t read the labels. Here are 10 tricksters to watch out for in particular!

    Don’t be fooled by healthy aesthetics on the packaging…

    Notwithstanding appearances and in many cases reputations, these all merit extra attention:

    • Yogurt: sweetened yogurts, especially “fruit at the bottom / in the corner” types, often have 15–30g of sugar per serving. Plain Greek yogurt is a better choice, offering 15–20g of protein with no added sugar. You can always add fresh fruits or spices like sweet cinnamon for flavor without added sugar.
    • Oatmeal: prepackaged oatmeal can contain 12–15 grams of added sugar per serving, similar to a glazed donut. Additionally, finely milled oats (as in “instant” oatmeal) can cause blood sugar spikes by itself, due to the loss of fiber. Better is plain oats, and if you like, you can sweeten them naturally with sweet cinnamon and/or fresh fruit for a healthier breakfast.
    • Sushi: while sushi contains nutritious fish, it often has too much white rice (and in the US, sushi rice is also often cooked with sugar to “improve” the taste and help cohesion) and sugary sauces. This makes many rolls much less healthy. So if fish (the sashimi component of sushi) is your thing, then focus on that, and minimize sugar intake for a more balanced meal.
    • Baked beans: store-bought baked beans can have up to 25g of added sugar per cup, similar to soda. Better to opt for plain beans and prepare them at home so that nothing is in them except what you personally put there.
    • Deli meats: deli meats are convenient but often are more processed than they look, containing preservatives linked to health risks. Fresh, unprocessed meats like chicken or turkey breast are healthier and can still be cost-effective when bought in bulk.
    • Fruit juices: fruit juices lack fiber (meaning their own natural sugars also become harmful, with no fiber to slow them down) and often contain added sugars too. Eating whole fruits is a much better way to get fiber, nutrients, and controlled healthy sugar intake.
    • Hazelnut spread: hazelnut spreads are usually 50% added sugar and contain unhealthy oils like palm oil. So, skip those, and enjoy natural nut butters for healthier fats and proteins.
    • Granola: granola is often loaded with added sugars and preservatives, so watch out for those.
    • Sports drinks: sports drinks, with 20–25g of added sugar per serving, are unnecessary and unhelpful (except, perhaps, in case of emergency for correcting diabetic hypoglycemia). Stick to water or electrolyte drinks—and even in the latter case, check the labels for added sugar and excessive sodium!
    • Dark chocolate: dark chocolate with 80% or more cocoa has health benefits but still typically contains a lot of added sugar. Check labels carefully!
