Most of us try to live rational lives. We try to make the best decisions we can based on the information we have… And if we’re thoughtful, we even try to be aware of common logical fallacies, and overcome our personal biases too. But is self-delusion ever useful?

Dr. Stuart Vyse, psychologist and Fellow for the Committee for Skeptical Inquiry, argues that it can be.

From self-fulfilling prophecies of optimism and pessimism, to the role of delusion in love and loss, Dr. Vyse explores what separates useful delusion from dangerous irrationality.

We also read about such questions as (and proposed answers to):

  • Why is placebo effect stronger if we attach a ritual to it?
  • Why are negative superstitions harder to shake than positive ones?
  • Why do we tend to hold to the notion of free will, despite so much evidence for determinism?

The style of the book is conversational, and captivating from the start; a highly compelling read.

Bottom line: if you’ve ever felt yourself wondering if you are deluding yourself and if so, whether that’s useful or counterproductive, this is the book for you!

  • 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)

  • What Does “Balance Your Hormones” Even Mean?

    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.

    Hormonal Health: Is It Really A Balancing Act?

    Have you ever wondered what “balancing your hormones” actually means?

    The popular view is that men’s hormones look like this:

    Testosterone (less) ⟷ Testosterone (more)

    …And that women’s hormones look more like this:

    ♀︎ Estrogen ↭ Progesterone ⤵︎

    ⇣⤷ FSH ⤦ ↴ ☾ ⤹⤷ Luteinizing Hormone ⤦

    DHEA ↪︎ Gonadotrophin ⤾

    ↪︎ Testosterone? ⥅⛢

    Clear as mud, right?

    But, don’t worry, Supplements McHerbal Inc will sell you something guaranteed to balance your hormones!

    How can a supplement (or dietary adjustment) “balance” all that hotly dynamic chaos, and make everything “balanced”?

    The truth is, “balanced” in such a nebulous term, and this is why you will not hear endocrinologists using it. It’s used in advertising to mean “in good order”, and “not causing problems”, and “healthy”.

    In reality, our hormone levels depend on everything from our diet to our age to our anatomy to our mood to the time of the day to the phase of the moon.

    Not that the moon has an influence on our physiology at all—that’s a myth—but you know, 28 day cycle and all. And, yes, half the hormones affect the levels of the others, either directly or indirectly.

    Trying to “balance” them would be quite a game of whack-a-mole, and not something that a “cure-all” single “hormone-balancing” supplement could do.

    So why aren’t we running this piece on Friday, for our “mythbusting” section? Well, we could have, but the more useful information is yet to come and will take up more of today’s newsletter than the myth-busting!

    What, then, can we do to untangle the confusion of these hormones?

    Well first, let’s understand what they do, in the most simple terms possible:

    • Estrogen—the most general feminizing hormone from puberty onwards, busiest in the beginning of the menstrual cycle, and starts getting things ready for ovulation.
    • Progesteronesecondary feminizing hormone, fluffs the pillows for the oncoming fertilized egg to be implanted, increases sex drive, and adjusts metabolism accordingly. Busiest in the second half of the menstrual cycle.
    • Testosterone—is also present, contributes to sex drive, is often higher in individuals with PCOS. If menopause is untreated, testosterone will also rise, because there will be less estrogen
      • (testosterone and estrogen “antagonize” each other, which is the colorfully scientific way of saying they work against each other)
      • DHEA—Dehydroepiandrosterone, supports production of testosterone (and estrogen!). Sounds self-balancing, but in practice, too much DHEA can thus cause elevated testosterone levels, and thus hirsutism.
    • Gonadotrophin—or more specifically human chorionic gonadotrophin, HcG, is “the pregnancy hormone“, present only during pregnancy, and has specific duties relating to such. This is what’s detected in (most) pregnancy test kits.
    • FSH—follicle stimulating hormone, is critical to ovulation, and is thus essential to female fertility. On the other hand, when the ovaries stop working, FSH levels will rise in a vain attempt to encourage the ovulation that isn’t going to happen anymore.
    • Luteinizing hormone—says “go” to the new egg and sends it on its merry way to go get fertilized. This is what’s detected by ovulation prediction kits.

    Sooooooo…

    What, for most women, most often is meant by a “hormonal imbalance” is:

    • Low levels of E and/or P
    • High levels of DHEA and/or T
    • Low or High levels of FSH

    In the case of low levels of E and/or P, the most reliable way to increase these is, drumroll please… To take E and/or P. That’s it, that’s the magic bullet.

    Bonus Tip: take your E in the morning (this is when your body will normally make more and use more) take your P in the evening (it won’t make you sleepy, but it will improve your sleep quality when you do sleep)

    In the case of high levels of DHEA and/or T, then that’s a bit more complex:

    • Taking E will antagonize (counteract) the unwanted T.
    • Taking T-blockers (such as spironolactone or bicalutamide) will do what it says on the tin, and block T from doing the jobs it’s trying to do, but the side-effects are considered sufficient to not prescribe them to most people.
    • Taking spearmint or saw palmetto will lower testosterone’s effects
      • Scientists aren’t sure how or why spearmint works for this
      • Saw palmetto blocks testosterone’s conversion into a more potent form, DHT, and so “detoothes” it a bit. It works similarly to drugs such as finasteride, often prescribed for androgenic alopecia, called “male pattern baldness”, but it affects plenty of women too.

    In the case of low levels of FSH, eating leafy greens will help.

    In the case of high levels of FSH, see a doctor. HRT (Hormone Replacement Therapy) may help. If you’re not of menopausal age, it could be a sign something else is amiss, so it could be worth getting that checked out too.

    What can I eat to boost my estrogen levels naturally?

    A common question. The simple answer is:

    • Flaxseeds and soy contain plant estrogens that the body can’t actually use as such (too incompatible). They’ve lots of high-quality nutrients though, and the polyphenols and isoflavones can help with some of the same jobs when it comes to sexual health.
    • Fruit, especially peaches, apricots, blueberries, and strawberries, contain a lot of lignans and also won’t increase your E levels as such, but will support the same functions and reduce your breast cancer risk.
    • Nuts, especially almonds (yay!), cashews, and pistachios, contain plant estrogens that again can’t be used as bioidentical estrogen (like you’d get from your ovaries or the pharmacy) but do support heart health.
    • Leafy greens and cruciferous vegetables support a lot of bodily functions including good hormonal health generally, in ways that are beyond the scope of this article, but in short: do eat your greens!

    Note: because none of these plant-estrogens or otherwise estrogenic nutrients can actually do the job of estradiol (the main form of estrogen in your body), this is why they’re still perfectly healthy for men to eat too, and—contrary to popular “soy boy” social myths—won’t have any feminizing effects whatsoever.

    On the contrary, most of the same foods support good testosterone-related health in men.

    The bottom line:

    • Our hormones are very special, and cannot be replaced with any amount of herbs or foods.
    • We can support our body’s natural hormonal functions with good diet, though.
    • Our hormones naturally fluctuate, and are broadly self-correcting.
    • If something gets seriously out of whack, you need an endocrinologist, not a homeopath or even a dietician.

    In case you missed it…

  • Why it’s a bad idea to mix alcohol with some medications

    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.

    Anyone who has drunk alcohol will be familiar with how easily it can lower your social inhibitions and let you do things you wouldn’t normally do.

    But you may not be aware that mixing certain medicines with alcohol can increase the effects and put you at risk.

    When you mix alcohol with medicines, whether prescription or over-the-counter, the medicines can increase the effects of the alcohol or the alcohol can increase the side-effects of the drug. Sometimes it can also result in all new side-effects.

    How alcohol and medicines interact

    The chemicals in your brain maintain a delicate balance between excitation and inhibition. Too much excitation can lead to convulsions. Too much inhibition and you will experience effects like sedation and depression.

    Alcohol works by increasing the amount of inhibition in the brain. You might recognise this as a sense of relaxation and a lowering of social inhibitions when you’ve had a couple of alcoholic drinks.

    With even more alcohol, you will notice you can’t coordinate your muscles as well, you might slur your speech, become dizzy, forget things that have happened, and even fall asleep.

    Alcohol can affect the way a medicine works.
    Jonathan Kemper/Unsplash

    Medications can interact with alcohol to produce different or increased effects. Alcohol can interfere with the way a medicine works in the body, or it can interfere with the way a medicine is absorbed from the stomach. If your medicine has similar side-effects as being drunk, those effects can be compounded.

    Not all the side-effects need to be alcohol-like. Mixing alcohol with the ADHD medicine ritalin, for example, can increase the drug’s effect on the heart, increasing your heart rate and the risk of a heart attack.

    Combining alcohol with ibuprofen can lead to a higher risk of stomach upsets and stomach bleeds.

    Alcohol can increase the break-down of certain medicines, such as opioids, cannabis, seizures, and even ritalin. This can make the medicine less effective. Alcohol can also alter the pathway of how a medicine is broken down, potentially creating toxic chemicals that can cause serious liver complications. This is a particular problem with paracetamol.

    At its worst, the consequences of mixing alcohol and medicines can be fatal. Combining a medicine that acts on the brain with alcohol may make driving a car or operating heavy machinery difficult and lead to a serious accident.

    Who is at most risk?

    The effects of mixing alcohol and medicine are not the same for everyone. Those most at risk of an interaction are older people, women and people with a smaller body size.

    Older people do not break down medicines as quickly as younger people, and are often on more than one medication.

    Older people also are more sensitive to the effects of medications acting on the brain and will experience more side-effects, such as dizziness and falls.

    Smaller and older people are often more affected.
    Alfonso Scarpa/Unsplash

    Women and people with smaller body size tend to have a higher blood alcohol concentration when they consume the same amount of alcohol as someone larger. This is because there is less water in their bodies that can mix with the alcohol.

    What drugs can’t you mix with alcohol?

    You’ll know if you can’t take alcohol because there will be a prominent warning on the box. Your pharmacist should also counsel you on your medicine when you pick up your script.

    The most common alcohol-interacting prescription medicines are benzodiazepines (for anxiety, insomnia, or seizures), opioids for pain, antidepressants, antipsychotics, and some antibiotics, like metronidazole and tinidazole.

    Medicines will carry a warning if you shouldn’t take them with alcohol.
    Nial Wheate

    It’s not just prescription medicines that shouldn’t be mixed with alcohol. Some over-the-counter medicines that you shouldn’t combine with alcohol include medicines for sleeping, travel sickness, cold and flu, allergy, and pain.

    Next time you pick up a medicine from your pharmacist or buy one from the local supermarket, check the packaging and ask for advice about whether you can consume alcohol while taking it.

    If you do want to drink alcohol while being on medication, discuss it with your doctor or pharmacist first.The Conversation

    Our Verdict

    When comparing extra virgin olive oil to cold-pressed coconut oil, we picked the olive oil.

    Why?

    While the cold-pressed coconut oil may offer some health benefits due to its lauric acid content, its 80–90% saturated fat content isn’t great for most people. It’s a great oil when applied topically for healthy skin and hair, though!

    The extra virgin olive oil has a much more uncontroversially healthy blend of triglycerides, and (in moderation) is universally recognized as very heart-healthy.

    Your local supermarket, most likely, has a good extra virgin olive oil, but if you’d like to get some online, here’s an example product on Amazon for your convenience.

  • Dioscorea Villosa: Hormones, Arthritis, & Skin

    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.

    On A Wild Yam Chase?

    We recently came across a supplement blend that had wild yam extract as a minor ingredient. Our plucky (and usually very knowledgable) researcher had never heard of its use before, so she set about doing her thing. This is what she found…

    What health claims are made?

    Wild yam extract (Dioscorea villosa) is traditionally sold and used for:

    • Balancing hormones
    • Combating arthritis
    • Anti-aging effects for the skin

    Does it balance hormones?

    First, as a quick catch-up, we’ll drop a previous article of ours for your convenience:

    What Does “Balance Your Hormones” Even Mean?

    We couldn’t find almost any studies into wild yam extract’s hormone-balancing effects, but we did find one study, and:

    ❝Symptom scores showed a minor effect of both placebo and active treatment on diurnal flushing number and severity and total non-flushing symptom scores, and on nocturnal sweating after placebo, but no statistical difference between placebo and active creams.

    This study suggests that short-term treatment with topical wild yam extract in women suffering from menopausal symptoms is free of side-effects, but appears to have little effect on menopausal symptoms❞

    …which is a very thorough, polite, sciencey way of saying “wow, this does so many different kinds of nothing”

    Source: Effects of wild yam extract on menopausal symptoms, lipids and sex hormones in healthy menopausal women

    On the one hand, this was a small study (n=23). On the other hand, it was also literally the only study we could find.

    Does it combat arthritis?

    Maybe! We again didn’t find much research into this but we did find two in vitro studies that suggests that diosgenin (which can be derived from wild yam extract) helps:

    And we also found a rodent study that found that wild yam extract specifically helped against “acetic acid-induced writhing and formalin-induced pain“, and put that down to anti-inflammatory properties:

    Read: Bioassay-guided evaluation of Dioscorea villosa – an acute and subchronic toxicity, antinociceptive and anti-inflammatory approach

    So, none of these studies tell us much about whether it would be helpful for humans—with or without arthritis, and hopefully without “acetic acid-induced writhing and formalin-induced pain”.

    However, they do suggest that it would be reasonable to test in humans next.

    You might prefer:

    Does it keep skin young?

    Again, research is thin on the ground, but we did find some! A study with wild-yam-derived diosgenin found that it didn’t make anything worse, and otherwise performed a similar role to vitamin A:

    Read: Novel effects of diosgenin on skin aging

    That was on rats with breast cancer though, so its applicability to healthy humans may be tenuous (while in contrast, simply getting vitamin A instead is a known deal).

    Summary

    • Does it balance hormones? It probably does little to nothing in this regard
    • Does it combat arthritis? It probably has anti-inflammatory effects, but we know of no studies in humans. There are much more well-established anti-inflammatories out there.
    • Does it keep the skin young? We know that it performs a role similar to vitamin A for rats with breast cancer, and didn’t make anything worse for them. That’s the extent of what we know.

    Where can I get some?

    In the unlikely event that the above research review has inspired you with an urge to buy wild yam extract, here is an example product for your convenience.

    Some final words…

    If you are surprised that we’re really not making any effort to persuade you of its merits, please know that (outside of the clearly-marked sponsor section, which helps us keep the lights on, so please do visit those) we have no interest in selling you anything. We’re genuinely just here to inform 🙂

    If you are wondering why we ran this article at all if the supplement has negligible merits, it’s because science is science, knowledge is knowledge, and knowing that something has negligible merit can be good knowledge to have!

    Also, running articles like this from time to time helps you to know that when we do sing the praises of something, it’s with good reason

    Take care!

    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

    ❝Hi, do you have anything helpful on avoiding PFAs?❞

    PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are “forever chemicals” made specifically to avoid degradation of industrial and chemical products. Which is great for providing stain and water resistance, but not so great for our bodies or the environment.

    To go into all the harms they cause would take a main feature (maybe we will, one of these days), but suffice it to say, they’re not good, and range from cancer and insulin resistance to hypertension and reduced immune response.

    To answer your question in a nutshell, avoiding them completely would be almost impossible, but we can reduce our exposure a lot by avoiding single-use food/drink products that have been waterproofed, e.g. paper/bamboo straws, utensils, cups, dishes, take-out containers, etc.

    Also, anything advertised as “stain-resistant” that you suspect should be quite stainable by nature, is probably good to avoid too.

    For more detailed information than we have room for here today, here’s a helpful overview:
