How do we successfully balance “a mind is like a parachute: it only works if it’s open”, with the importance of also actually having some kind of personal integrity and consistency?

Dr. Fox recommends that we focus on four key attributes:

  • Mental agility
  • Self-awareness
  • Emotional awareness
  • Situational awareness

If this sounds a little wishy-washy, it isn’t—she delineates and explains each in detail. And most importantly: how we can build and train each one.

Mental agility, for example, is not about being able to rapidly solve chess problems or “answer these riddles three”. It’s more about:

  • Adaptability
  • Balancing our life
  • Challenging (and if appropriate, changing) our perspective
  • Developing our mental competence

This sort of thing is the “meat” of the book. Meanwhile, self-awareness is more a foundational conscious knowledge of one’s own “pole star” values, while emotional awareness is a matter of identifying and understanding and accepting what we feel—anything less is self-sabotage! And situational awareness is perhaps most interesting:

Dr. Fox advocates for “trusting one’s gut feelings”. With a big caveat, though!

If we trust our gut feelings without developing their accuracy, we’re just going to go about being blindly prejudiced and often wrong. So, a whole section of the book is devoted to honing this and improving our ability to judge things as they really are—rather than as we expect.

Bottom line: this book is a great tool for not only challenging our preconceptions about how we think, but giving us the resources to be adaptable and resilient without sacrificing integrity.

  • The Wandering Mind – by Dr. Michael Corballis

    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 mind’s tendency to wander can be a disability, but could it also be a superpower? Dr. Corballis makes the case for such.

    While many authors focus on, well, how to focus, Dr. Corballis argues in this book that our wandering imagination can be more effective at problem-solving and creative tasks, than a focused, blinkered mind.

    The book’s a quick read (184 pages of quite light reading), and yet still quite dense with content. He takes us on a tour of the brain, theory of mind, the Default Mode Network (where a lot of the brain’s general ongoing organization occurs), learning, memory, forgetting, and creativity.

    Furthermore, he cites (and explains) studies showing what kinds of “breaks” from mental work allow the wandering mind to do its thing at peak efficiency, and what kinds of breaks are counterproductive. Certainly this has practical applications for all of us!

    Bottom line: if you’d like to be less frustrated by your mind’s tendency to wander, this is a fine book to show how to leverage that trait to your benefit.

  • Ice Baths: To Dip Or Not To Dip?

    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.

    Many Are Cold, But Few Are Frozen

    We asked you for your (health-related) view of ice baths, and got the above-depicted, below-described, set of responses:

    • About 31% said “ice baths are great for the health; we should take them”
    • About 29% said “ice baths’ risks outweigh their few benefits”
    • About 26% said “ice baths’ benefits outweigh their few risks”
    • About 14% said “ice baths are dangerous and can kill you; best avoided”

    So what does the science say?

    Freezing water is very dangerous: True or False?

    True! Water close to freezing point is indeed very dangerous, and can most certainly kill you.

    Fun fact, though: many such people are still saveable with timely medical intervention, in part because the same hypothermia that is killing them also slows down the process* of death

    Source (and science) for both parts of that:

    Cold water immersion: sudden death and prolonged survival

    *and biologically speaking, death is a process, not an event, by the way. But we don’t have room for that today!

    (unless you die in some sudden violent way, such as a powerful explosion that destroys your brain instantly; then it’s an event)

    Ice baths are thus also very dangerous: True or False?

    False! Assuming that they are undertaken responsibly and you have no chronic diseases that make it more dangerous for you.

    What does “undertaken responsibly” mean?

    Firstly, the temperature should not be near freezing. It should be 10–15℃, which for Americans is 50–59℉.

    You can get a bath thermometer to check this, by the way. Here’s an example product on Amazon.

    Secondly, your ice bath should last no more than 10–15 minutes. This is not a place to go to sleep.

    What chronic diseases would make it dangerous?

    Do check with your doctor if you have any doubts, as no list we make can be exhaustive and we don’t know your personal medical history, but the main culprits are:

    • Cardiovascular disease
    • Hypertension
    • Diabetes (any type)

    The first two are for heart attack risk; the latter is because diabetes can affect core temperature regulation.

    Ice baths are good for the heart: True or False?

    True or False depending on how they’re done, and your health before starting.

    For most people, undertaking ice baths responsibly, repeated ice bath use causes the cardiovascular system to adapt to better maintain homeostasis when subjected to thermal shock (i.e. sudden rapid changes in temperature).

    For example: Respiratory and cardiovascular responses to cold stress following repeated cold water immersion

    And because that was a small study, here’s a big research review with a lot of data; just scroll to where it has the heading“Specific thermoregulative adaptations to regular exposure to cold air and/or cold water exposure“ for many examples and much discussion:

    Health effects of voluntary exposure to cold water: a continuing subject of debate

    Ice baths are good against inflammation: True or False?

    True! Here’s one example:

    Winter-swimming as a building-up body resistance factor inducing adaptive changes in the oxidant/antioxidant status

    Uric acid and glutathione levels (important markers of chronic inflammation) are also significantly affected:

    Uric acid and glutathione levels during short-term whole body cold exposure

  • The Coffee-Cortisol Connection, And Two Ways To Tweak It 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.

    Health opinions on coffee vary from “it’s an invigorating, healthful drink” to “it will leave you a shaking frazzled wreck”. So, what’s the truth and can we enjoy it healthily? Dr. Alan Mandell weighs in:

    Enjoy it, but watch out!

    Dr. Mandell is speaking only for caffeinated coffee in this video, and to this end, he’s conflating the health effects of coffee and caffeine. A statistically reasonable imprecision, since most people drink coffee with its natural caffeine in, but we’ll make some adjustment to his comments below, to disambiguate which statements are true for coffee generally, and which are true for caffeine:

    • Drinking coffee caffeine first thing in the morning may not be ideal due to dehydration from overnight water loss.
    • Coffee caffeine is a diuretic, which means an increase in urination, thus further dehydrating the body.
    • Coffee contains great antioxidants, which are of course beneficial for the health in general.
    • Cortisol, the body’s stress hormone, is generally at its peak in the morning. This is, in and of itself, good and correct—it’s how we wake up.
    • Coffee caffeine consumption raises cortisol levels even more, leading to increased alertness and physical readiness, but it is possible to have too much of a good thing, and in this case, problems can arise because…
    • Elevated cortisol from early coffee caffeine drinking can build tolerance, leading to the need for more coffee caffeine over time.
    • It’s better, therefore, to defer drinking coffee caffeine until later in the morning when cortisol levels naturally drop.
    • All of this means that drinking coffee caffeine first thing can disrupt the neuroendocrine system, leading to fatigue, depression, and general woe.
    • Hydrate first thing in the morning before consuming coffee caffeine to keep the body balanced and healthy.

    What you can see from this is that coffee and caffeine are not, in fact, interchangeable words, but the basic message is clear and correct: while a little spike of cortisol in the morning is good, natural, and even necessary, a big spike is none of those things, and caffeine can cause a big spike, and since for most people caffeine is easy to build tolerance to, there will indeed consistently be a need for more, worsening the problem.

    In terms of hydration, it’s good to have water (or better yet, herbal tea) on one’s nightstand to drink when one wakes up.

    If coffee is an important morning ritual for you, consider finding a good decaffeinated version for at least your first cup (this writer is partial to Lavazza’s “Dek Intenso”—which is not the same as their main decaf line, by the way, so do hold out for the “Dek Intenso” if you want to try my recommendation).

    Decaffeinated coffee is hydrating and will not cause a cortisol spike (unless for some reason you find coffee as a concept very stressful in which case, yes, the stressor will cause a stress response).

    Anyway, for more on all of this, enjoy:

  • Black Cohosh vs The Menopause

    Black Cohosh, By Any Other Name…

    Black cohosh is a flowering plant whose extracts are popularly used to relieve menopausal (and postmenopausal) symptoms.

    Note on terms: we’ll use “black cohosh” in this article, but if you see the botanical names in studies, the reason it sometimes appears as Actaea racemosa and sometimes as Cimicfuga racemosa, is because it got changed and changed back on account of some disagreements between botanists. It’s the same plant, in any case!

    Read: Reclassification of Actaea to include Cimicifuga and Souliea (Ranunculaceae)

    Does it work?

    In few words: it works for physical symptoms, but not emotional ones, based on this large (n=2,310) meta-analysis of studies:

    ❝Black cohosh extracts were associated with significant improvements in overall menopausal symptoms (Hedges’ g = 0.575, 95% CI = 0.283 to 0.867, P < 0.001), as well as in hot flashes (Hedges’ g = 0.315, 95% CIs = 0.107 to 0.524, P = 0.003), and somatic symptoms (Hedges’ g = 0.418, 95% CI = 0.165 to 0.670, P = 0.001), compared with placebo.

    However, black cohosh did not significantly improve anxiety (Hedges’ g = 0.194, 95% CI = -0.296 to 0.684, P = 0.438) or depressive symptoms (Hedges’ g = 0.406, 95% CI = -0.121 to 0.932, P = 0.131)❞

    ~ Dr. Ryochi Sadahiro et al., 2023

    Source: Black cohosh extracts in women with menopausal symptoms: an updated pairwise meta-analysis

    Here’s an even larger (n=43,759) one that found similarly, and also noted on safety:

    ❝Treatment with iCR/iCR+HP was well tolerated with few minor adverse events, with a frequency comparable to placebo. The clinical data did not reveal any evidence of hepatotoxicity.

    Hormone levels remained unchanged and estrogen-sensitive tissues (e.g. breast, endometrium) were unaffected by iCR treatment.

    As benefits clearly outweigh risks, iCR/iCR+HP should be recommended as an evidence-based treatment option for natural climacteric symptoms.

    With its good safety profile in general and at estrogen-sensitive organs, iCR as a non-hormonal herbal therapy can also be used in patients with hormone-dependent diseases who suffer from iatrogenic climacteric symptoms.❞

    ~ Dr. Castelo-Branco et al., 2020

    Source: Review & meta-analysis: isopropanolic black cohosh extract iCR for menopausal symptoms – an update on the evidence

    (iCR = isopropanolic Cimicifuga racemosa)

    So, is this estrogenic or not?

    This is the question many scientists were asking, about 20 or so years ago. There are many papers from around 2000–2005, but here’s a good one that’s quite representative:

    ❝These new data dispute the estrogenic theory and demonstrate that extracts of black cohosh do not bind to the estrogen receptor in vitro, up-regulate estrogen-dependent genes, or stimulate the growth of estrogen-dependent tumors❞

    ~ Dr. Gail Mahady, 2003

    Source: Is Black Cohosh Estrogenic?

    (the abstract is a little vague, but if you click on the PDF icon, you can read the full paper, which is a lot clearer and more detailed)

    The short answer: no, black cohosh is not estrogenic

    Is it safe?

    As ever, check with your doctor as everyone’s situation can vary, but broadly speaking, yes, it has a very good safety profileincluding for breast cancer patients, at that. See for example:

  • Cordyceps: Friend Or Foe?

    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.

    Cordyceps: friend or foe?

    Cordyceps is a famously frightening fungus. It’s the one responsible for “zombie ants” and other zombie creatures, and it’s the basis for the existential threat to humanity in the TV show The Last of Us.

    It’s a parasitic fungus that controls the central and peripheral nervous systems of its host, slowly replacing the host’s body, as well as growing distinctive spines that erupt out of the host’s body. Taking over motor functions, it compels the host to do two main things, which are to eat more food, and climb to a position that will be good to release spores from.

    Fortunately, none of that matters to humans. Cordyceps does not (unlike in the TV show) affect humans that way.

    What does Cordyceps do in humans?

    Cordyceps (in various strains) is enjoyed as a health supplement, based on a long history of use in Traditional Chinese Medicine, and nowadays it’s coming under a scientific spotlight too.

    The main health claims for it are:

    • Against inflammation
    • Against aging
    • Against cancer
    • For blood sugar management
    • For heart health
    • For exercise performance

    Sounds great! What does the science say?

    There’s a lot more science for the first three (which are all closely related to each other, and often overlapping in mechanism and effect).

    So let’s take a look:

    Against inflammation

    The science looks promising for this, but studies so far have either been in vitro (cell cultures in petri dishes), or else murine in vivo (mouse studies), for example:

    In summary: we can see that it has anti-inflammatory properties for mice and in the lab; we’d love to see the results of studies done on humans, though. Also, while it has anti-inflammatory properties, it performed less well than commonly-prescribed anti-inflammatory drugs, for example:

    ❝C. militaris can modulate airway inflammation in asthma, but it is less effective than prednisolone or montelukast.❞

    Source: Effects of the immunomodulatory agent Cordyceps militaris on airway inflammation in a mouse asthma model

    Against aging

    Because examining the anti-aging effects of a substance requires measuring lifespans and repeating the experiment, anti-aging studies do not tend to be done on humans, because they would take lifetimes to perform. To this end, it’s inconvenient, but not a criticism of Cordyceps, that studies have been either mouse studies (short lifespan, mammals like us) or fruit fly studies (very short lifespan, genetically surprisingly similar to us).

    The studies have had positive results, with typical lifespan extensions of 15–20%:

    Against cancer

    Once again, the studies here have been in vitro, or murine in vivo. They do look good though:

    In vitro (human cell cultures in a lab):

    In vivo (mouse studies):

    Summary of these is: Cordyceps quite reliably inhibits tumor growth in vitro (human cell cultures) and in vivo (mouse studies). However, trials in human cancer patients are so far conspicuous by their absence.

    For blood sugar management

    Cordyceps appears to mimic the action of insulin, without triggering insulin sensitivity. For example:

    The anti-hyperglycemic activity of the fruiting body of Cordyceps in diabetic rats

    There were some other rat/mouse studies with similar results. No studies in humans yet.

    For heart health

    Cordyceps contains adenosine. You may remember that caffeine owes part of its stimulant effect to blocking adenosine, the hormone that makes us feel sleepy. So in this way, Cordyceps partially does the opposite of what caffeine does, and may be useful against arrhythmia:

    Cardiovascular protection of Cordyceps sinensis act partially via adenosine receptors

    For exercise performance

    A small (30 elderly participants) study found that Cordyceps supplementation improved VO2 max by 7% over the course of six weeks:

    Randomized double-blind placebo-controlled clinical trial and assessment of fermentation product of Cordyceps sinensis in enhancing aerobic capacity and respiratory function of the healthy elderly volunteers

    However, another small study (22 young athletes) failed to reproduce those results:

    Cordyceps Sinensis supplementation does not improve endurance exercise performance

    In summary…

    Cordyceps almost certainly has anti-inflammation, anti-aging, and anti-cancer benefits.

    Cordyceps may have other benefits too, but the evidence is thinner on the ground for those, so far.

  • 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.
