While reading this week’s health news, we’ve singled out three brain-related articles to feature here:

Bad breath now, bad brain later?

Researchers found links between oral microbiome populations, and changes in brain function with aging. The short version is indeed “bad breath now = bad brain later”, but more specifically:

  • People who had large numbers of the bacteria groups Neisseria and Haemophilus had better memory, attention and ability to do complex tasks
  • People who had higher levels of Porphyromonas had more memory problems later
  • People with a lot of Prevotella tended to predict poorer brain health and was more common in people who carry the Alzheimer’s Disease risk gene, APOE4.

If you’ve never heard of half of those, don’t worry: mostly your oral microbiome can take care of itself, provide you consistently do the things that create a “good” oral microbiome. So, see our “related” link below:

Weeding out a major cause of cognitive decline

Cannabis may be great for relaxation, but regular use is not great for mental sharpness, and recent use (even if not regular, and even if currently sober) shows a similar dip in cognitive abilities, especially working memory. In other words, cannabis use for relaxation should be at most an occasional thing, rather than an everyday thing.

While the results of the study are probably not shocking, something that we found interesting was their classification system:

❝Heavy users are considered young adults who’ve used cannabis more than 1000 times over their lifetime. Whereas, using 10 to 999 times was considered a moderate user, and fewer than 10 times was considered a non-user.❞

Which—while being descriptive rather than prescriptive in nature—suggests that, to be on the healthy end of the bell curve, an occasional cannabis-user might want to consider “if you have 999 uses before you hit the “heavy user” category, project those 999 uses against your life expectancy, and moderate your use accordingly”. In other words, a person just now starting use, who expects to live another 40 years, would calculate: 999/40 = 24.9 uses per year, so call it 2 per month. A person who only expects to live another 20 years, would do the same math and arrive at 4 per month.

Disclaimer: the above is intended as an interesting reframe, and a way of looking at long-term cannabis use while being mindful of the risks. It is not intended as advice. This health-conscious writer personally has no intention of using at all, unless perhaps in some bad future scenario in which I have bad chronic pain, I might consider that pain relief effects may be worth the downsides. Or I might not; I hope not to be in the situation to find out!

Mind-reading technology improves again

We’ve come quite a way from simple 1/0 reads, and basic cursor control! Now, researchers have created a brain decode that can translate a person’s thoughts into continuous text, without requiring the person to focus on words—in other words, it verbalizes the ideas directly. Most recently, the latest upgrade means that while previously, the device had to be trained on an individual brain for many hours, now the training/calibration process takes only an hour:

    Everyone knows the slogan “does this spark joy?”, but there’s a whole method to the magic that goes far beyond that. It spans all manner of things from the over-arching strategy of taking on a house-sized tidying project, to practical little tips like “store these things this way instead; now they’re safe, tidy and accessible—and look good too!”.

    You may be wondering: why are we reviewing this book instead of the much more famous “The Life-Changing Magic of Tidying Up”?

    It’s simple: here at 10almonds, we like things to be super simple and easy to digest.

    This book is smaller, simpler, and more digestible than her more famous book, without sacrificing content. And you know what? We held it in our hands and it sparked joy

    Bottom line is: it’s useful, it’s beautiful, it will change your life (and your underwear drawer).

    PS: this 10almonds team-member gifted a copy to her 12-year-old son. He implemented it the same day, unbidden. Magic indeed!

  • Intermittent Fasting, Intermittently?

    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 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 😎

    ❝Have you come across any research on alternate-day intermittent fasting—specifically switching between one day of 16:8 fasting and the next day of regular eating patterns? I’m curious if there are any benefits or drawbacks to this alternating approach, or if the benefits mainly come from consistent intermittent fasting?❞

    Short and unhelpful answer: no

    Longer and hopefully more helpful answer:

    As you probably know, usually people going for approaches based on the above terms either

    • practise 16:8 fasting (fast for 16 hours each day, eat during an 8-hour window) or
    • practise alternate-day fasting (fast for 24 hours, eat whenever for 24 hours, repeat)

    …which latter scored the best results in this large meta-analysis of studies:

    Effects of different types of intermittent fasting on metabolic outcomes: an umbrella review and network meta-analysis

    There is also the (popular) less extreme version of alternate-day fasting, sometimes called “eat stop eat”, which is not a very helpful description because that describes almost any kind of eating/fasting, but it usually refers to “once per week, take a day off from eating”.

    You can read more about each of these (and some other variants), here:

    Intermittent Fasting: What’s The Truth?

    What you are describing (doing 16:8 fasting on alternate days, eating whenever on the other days) is essentially: intermittent fasting, just with one 16-hour fast per 48 hours instead of per the usual 24 hours.

    See also: International consensus on fasting terminology ← the section on the terms “STF & PF” covers why this gets nudged back under the regular IF umbrella

    Good news: this means there is a lot of literature into the acute (i.e., occurring the same day, not long-term)* benefits of 16:8 IF, and that means that you will be getting those benefits, every second day.

    You remember that meta-analysis we posted above? While it isn’t mentioned in the conclusion (which only praised complete alternate-day fasting producing the best outcomes overall), sifting through the results data discovers that time-restricted eating (which is what you are doing, by these classifications) was the only fasting method to significantly reduce fasting blood glucose levels.

    (However, no significant differences were observed between any IF form and the reference (continuous energy restriction, CER, i.e. calorie-controlled) diets in fasting insulin and HbA1c levels)

    *This is still good news in the long-term though, because getting those benefits every second day is better than getting those benefits on no days, and this will have a long-term impact on your healthy longevity, just like how it is better to exercise every second day than it is to exercise no days, or better to abstain from alcohol every second day than it is to abstain on no days, etc.

    In short, by doing IF every second day, you are still giving your organs a break sometimes, and that’s good.

    All the same, if it would be convenient and practical for you, we would encourage you to consider either the complete alternate-day fasting (which, according to a lot of data, gives the best results overall),or time-restricted eating (TRE) every day (which, according to a lot of data, gives the best fasting blood sugar levels).

    You could also improve the TRE days by shifting to 20:4 (i.e., 20 hours fasting and 4 hours eating), this giving your organs a longer break on those days.

  • Almonds vs Cashews – 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 almonds to cashews, we picked the almonds.

    Why?

    Both are great! But here’s why we picked the almonds:

    In terms of macros, almonds have a little more protein and more than 4x the fiber. Given how critical fiber is to good health, and how most people in industrialized countries in general (and N. America in particular) aren’t getting enough, we consider this a major win for almonds.

    Things are closer to even for vitamins, but almonds have a slight edge. Almonds are higher in vitamins A, B2, B3, B9, and especially 27x higher in vitamin E, while cashews are higher in vitamins B1, B5, B6, C & K. So, a moderate win for almonds.

    In the category of minerals, cashews do a bit better on average. Cashews have moderately more copper, iron, phosphorus, selenium, and zinc, while almonds boast 6x more calcium, and slightly more manganese and potassium. We say this one’s a slight win for cashews.

    Adding the categories up, however, makes it clear that almonds win the day.

    However, of course, enjoy both! Diversity is healthy. Just, if you’re going to choose between them, we recommend almonds.

  • How Tight Are Your Hips? Test (And Fix!) With This

    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.

    Upon surveying over half a million people; hips were the most common area for stiffness and lack of mobility. So, what to do about it?

    This test don’t lie

    With 17 muscles contributing to hip function (“hip flexors” being the name for this group of 17 muscles, not specific muscle), it’s important to figure out which ones are tight, and if indeed it really is the hip flexors at all, or if it could be, as it often is, actually the tensor fasciae latae (TFL) muscle of the thigh. If it turns out to be both, well, that’s unfortunate but the good news is, now you’ll know and can start fixing from all the necessary angles.

    Diagnostic test for tight hip flexors (Thomas Test):

    1. Use a sturdy, elevated surface (e.g. table or counter—not a bed or couch, unless there is perchance room to swing your legs without them touching the floor).
    2. Sit at the edge, lie back, and pull both knees to your chest.
    3. Return one leg back down until the thigh is perpendicular to the table.
    4. Let the other leg dangle off the edge to assess flexibility.

    Observations from the test:

    1. Thigh contact: is the back of your thigh touching the table?
    2. Knee angle: is your knee bent at roughly 80° or straighter?
    3. Thigh rotation: does the thigh roll outward?

    Interpreting results:

    • If your thigh contacts the surface and the knee is bent at around 80°, hip mobility is good.
    • If your thigh doesn’t touch or knee is too straight, hip flexor tightness is present.
    • If your thigh rolls outwards from your midline, that indicates tightness in the TFL muscle of the thigh.

    Three best hip flexor stretches:

    1. Kneeling lunge stretch:
      • Hips above the knee, tuck tailbone, engage glutes, press hips forward, reach arm up with a slight side bend.
    2. Seated hip lift stretch:
      • Sit with feet hip-width apart, hands behind shoulders, lift hips, step one foot back, tuck tailbone, point knee away.
    3. Sofa stretch:
      • Kneel with one shin against a couch/wall, other foot forward in lunge, tuck tailbone, press hips forward, lift torso.

    It’s recommended to how each stretch for 30 seconds on each side.

  • This Chair Rocks: A Manifesto Against Ageism – by Ashton Applewhite

    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 easy to think of ageism as being 80% “nobody will hire me because I am three years away from standard retirement age”, but it’s a lot more pervasive than that. And some of it, perhaps the most insidious, is the ageism that we can sometimes internalize without thinking it through.

    10almonds readers love to avoid/reverse aging (and this reviewer is no different!), but it’s good once in a while to consider our priorities and motivations, for example:

    • There is merit in being able to live without disability or discomfort
    • There is harm in feeling a need to pass for younger than we are

    And yet, even things such as disabilities are, Applewhite fairly argues, not to be feared. Absolutely avoided if reasonably possible of course, yes, but if they happen they happen and it’s good that we be able to make our peace with that, because most people have at least some kind of disability before the end, and can still strive to make the most of the precious gift that is life. The goal can and should be to play the hand we’re dealt and to live as well as we can—whatever that latter means for us personally.

    Many people’s life satisfaction goes up in later years, and Applewhite hypothesizes that while some of that can be put down to circumstances (often no longer overwhelmed with work etc, often more financially stable), a lot is a matter of having come to terms with “losing” youth and no longer having that fear. Thus, a new, freer age of life begins.

    The book does cover many other areas too, more than we can list here (but for example: ranging from pro/con brain differences to sex and intimacy), and the idea that long life is a team sport, and that we should not fall into the all-American trap of putting independence on a pedestal. Reports of how aging works with close-knit communities in the supercentenarian Blue Zones can be considered to quash this quite nicely, for instance.

    The style is casual and entertaining, and yet peppered with scholarly citations, which stack up to 30 pages of references at the back.

    Bottom line: getting older is a privilege that not everyone gets to have, so who are we to squander it? This book shares a vital sense of perspective, and is a call-to-arms for us all to do better, together.

  • ADHD 2.0 – by Dr. Edward Hallowell & Dr. John Ratey

    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 lot of ADHD literature is based on the assumption that the reader is a 30-something parent of a child with ADHD. This book, on the other hand, addresses all ages, and includes just as readily the likelihood that the person with ADHD is the reader, and/or the reader’s partner.

    The authors cover such topics as:

    • ADHD mythbusting, before moving on to…
    • The problems of ADHD, and the benefits that those exact same traits can bring too
    • How to leverage those traits to get fewer of the problems and more of the benefits
    • The role of diet beyond the obvious, including supplementation
    • The role of specific exercises (especially HIIT, and balance exercises) in benefiting the ADHD brain
    • The role of medications—and arguments for and gainst such

    The writing style is… Thematic, let’s say. The authors have ADHD and it shows. So, expect comprehensive deep-dives from whenever their hyperfocus mode kicked in, and expect no stones left unturned. That said, it is very readable, and well-indexed too, for ease of finding specific sub-topics.

    Bottom line: if you are already very familiar with ADHD, you may not learn much, and might reasonably skip this one. However, if you’re new to the topic, this book is a great—and practical—primer.
