Biological aging is not truly just one thing, but rather the amalgam of many things intersecting—and most of them are modifiable. The cells of your body neither know nor care how many times you have flown around the sun; they just respond to the stimuli they’re given.

Which is what fuels this book. The idea is to have a brain that is less-assailed by the things that would make it age, and more rejuvenated by the things that can make it biologically younger.

Dr. Milstein doesn’t neglect the rest of the body, and indeed notes the brain’s connections with the immune system, the heart, the gut, and more. But everything in this book is done with the brain in mind and its good health as the top priority outcome of all the things he advises.

On which note, yes, there is plenty of practical, implementable advice here. For a book that is consistently full of study paper citations, he does take care to make everything useful to the reader, and makes everything as easy as possible for the layperson along the way.

Bottom line: if you would like your brain to age less, this is an excellent, very evidence-based, guidebook.

    They are healthy, they are tasty, they are convenient! Make some of these and when you need an energizing treat at silly o’clock when you don’t have time to prepare something, here they are, full of antioxidants, vitamins and minerals, good for blood sugars too, and ready to go:

    You will need

    • 1 cup pitted dates
    • 1 cup raw mixed nuts
    • ¼ cup goji berries
    • 1 tbsp cocoa powder
    • 1 tsp chili flakes

    Naturally, you can adjust the spice level if you like! But this is a good starter recipe.

    Method

    (we suggest you read everything at least once before doing anything)

    1) Blend all the ingredients in a good processor to make a dough

    2) Roll the dough into 1″ balls; you should have enough dough for about 16 balls. If you want them to be pretty, you can roll them in some spare dry ingredients (e.g. chopped nuts, goji berries, chili flakes, seeds of some kind, whatever you have in your kitchen that fits the bill).

    3) Refrigerate for at least 1–2 hours, and serve! They can also be kept in the fridge for at least a good while—couldn’t tell you how long for sure though, because honestly, they’ve never stayed that long in the fridge without being eaten.

    Enjoy!

  • Hormones & Health, Beyond The Obvious

    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.

    Wholesome Health

    This is Dr. Sara Gottfried, who some decades ago got her MD from Harvard and specialized as an OB/GYN at MIT. She’s since then spent the more recent part of her career educating people (mostly: women) about hormonal health, precision, functional, & integrative medicine, and the importance of lifestyle medicine in general.

    What does she want us to know?

    Beyond “bikini zone health”

    Dr. Gottfried urges us to pay attention to our whole health, in context.

    “Women’s health” is often thought of as what lies beneath a bikini, and if it’s not in those places, then we can basically treat a woman like a man.

    And that’s often not actually true—because hormones affect every living cell in our body, and as a result, while prepubescent girls and postmenopausal women (specifically, those who are not on HRT) may share a few more similarities with boys and men of similar respective ages, for most people at most ages, men and women are by default quite different metabolically—which is what counts for a lot of diseases! And note, that difference is not just “faster” or “slower””, but is often very different in manner also.

    That’s why, even in cases where incidence of disease is approximately similar in men and women when other factors are controlled for (age, lifestyle, medical history, etc), the disease course and response to treatment may vary considerable. For a strong example of this, see for example:

    • The well-known: Heart Attack: His & Hers ← most people know these differences exist, but it’s always good to brush up on what they actually are
    • The less-known: Statins: His & Hers ← most people don’t know these differences exist, and it pays to know, especially if you are a woman or care about one

    Nor are brains exempt from his…

    The female brain (kinda)

    While the notion of an anatomically different brain for men and women has long since been thrown out as unscientific phrenology, and the idea of a genetically different brain is… Well, it’s an unreliable indicator, because technically the cells will have DNA and that DNA will usually (but not always; there are other options) have XX or XY chromosomes, which will usually (but again, not always) match apparent sex (in about 1/2000 cases there’s a mismatch, which is more common than, say, red hair; sometimes people find out about a chromosomal mismatch only later in life when getting a DNA test for some unrelated reason), and in any case, even for most of us, the chromosomal differences don’t count for much outside of antenatal development (telling the default genital materials which genitals to develop into, though this too can get diverted, per many intersex possibilities, which is also a lot more common than people think) or chromosome-specific conditions like colorblindness…

    The notion of a hormonally different brain is, in contrast to all of the above, a reliable and easily verifiable thing.

    See for example:

    Alzheimer’s Sex Differences May Not Be What They Appear

    Dr. Gottfried urges us to take the above seriously!

    Because, if women get Alzheimer’s much more commonly than men, and the disease progresses much more quickly in women than men, but that’s based on postmenopausal women not on HRT, then that’s saying “Women, without women’s usual hormones, don’t do so well as men with men’s usual hormones”.

    She does, by the way, advocate for bioidentical HRT for menopausal women, unless contraindicated for some important reason that your doctor/endocrinologist knows about. See also:

    Menopausal HRT: A Tale Of Two Approaches (Bioidentical vs Animal)

    The other very relevant hormone

    …that Dr. Gottfried wants us to pay attention to is insulin.

    Or rather, its scrubbing enzyme, the prosaically-named “insulin-degrading enzyme”, but it doesn’t only scrub insulin. It also scrubs amyloid beta—yes, the same that produces the amyloid beta plaques in the brain associated with Alzheimer’s. And, there’s only so much insulin-degrading enzyme to go around, and if it’s all busy breaking down excess insulin, there’s not enough left to do the other job too, and thus can’t break down amyloid beta.

    In other words: to fight neurodegeneration, keep your blood sugars healthy.

    This may actually work by multiple mechanisms besides the amyloid hypothesis, by the way:

  • The Blood Sugar Solution – by Dr. Mark Hyman

    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.

    The main purpose of this book is combating metabolic disease, the amalgam of what’s often prediabetes (sometimes fully-fledged diabetes) and cardiovascular disease (sometimes fully-fledged heart disease).

    To achieve this (after an introductory section explaining what the sociomedical problems are and why the sociomedical problems are happening), he offers a seven-step program; we’ll not keep those steps a mystery; they are:

    1. Boost your nutrition
    2. Regulate your hormones
    3. Reduce inflammation
    4. Improve your digestion
    5. Maximize detoxification
    6. Enhance energy metabolism
    7. Soothe your mind

    Thereafter, it’s all about leading the reader by the hand through the steps; he also offers a six-week action plan, and a six-week meal plan with recipes.

    The style is very sensationalist (too sensationalist for this reviewer’s personal taste) but nevertheless backed up with hard science when it comes to hard claims. So, if you don’t mind wading through (or skipping) some early chapters that are a bit “used car salesman” in feel, there’s actually a lot of good information, especially in the middle of the book, and useful practical guides in the middle and end.

    Bottom line: if you want a good comprehensive science-based practical guide to addressing the risk of metabolic disease, this is that.

    Anosmia, by any other name…

    The loss of the sense of smell (anosmia) is these days well-associated with COVID and Long-COVID, but also can simply come with age:

    National Institute of Aging | How Smell & Taste Change With Age

    …although it can also be something else entirely:

    ❝Another possibility is a problem with part of the nervous system responsible for smell.

    Some studies have suggested that loss of smell could be an early sign of a neurodegenerative disease, such as Alzheimer’s or Parkinson’s disease.

    However, a recent study of 1,430 people (average age about 80) showed that 76% of people with anosmia had normal cognitive function at the study’s end.❞

    Read more: Harvard Health | Is it normal to lose my sense of smell as I age?

    We’d love to look at and cite the paper that they cite, but they didn’t actually provide a source. We did find some others, though:

    ❝Olfactory capacity declines with aging, but increasing evidence shows that smell dysfunction is one of the early signs of prodromal neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease.

    The loss of smell is considered a clinical sign of early-stage disease and a marker of the disease’s progression and cognitive impairment.❞

    ~ Dr. Irene Fatuzzo et al.

    Read more: Neurons, Nose, and Neurodegenerative Diseases: Olfactory Function and Cognitive Impairment

    What’s clear is the association; what’s not clear is whether one worsens the other, and what causal role each might play. However, the researchers conclude that both ways are possible, including when there is another, third, underlying potential causal factor:

    ❝Ongoing studies on COVID-19 anosmia could reveal new molecular aspects unexplored in olfactory impairments due to neurodegenerative diseases, shedding a light on the validity of smell test predictivity of cognitive dementia.

    The neuroepithelium might become a new translational research target (Neurons, Nose, and Neurodegenerative diseases) to investigate alternative approaches for intranasal therapy and the treatment of brain disorders. ❞

    ~ Ibid.

    Another study explored the possible mechanisms of action, and found…

    ❝Olfactory impairment was significantly associated with increased likelihoods of MCI, amnestic MCI, and non-amnestic MCI.

    In the subsamples, anosmia was significantly associated with higher plasma total tau and NfL concentrations, smaller hippocampal and entorhinal cortex volumes, and greater WMH volume, and marginally with lower AD-signature cortical thickness.

    These results suggest that cerebral neurodegenerative and microvascular lesions are common neuropathologies linking anosmia with MCI in older adults❞

    How to act on this information

    You may be wondering, “this is fascinating and maybe even a little bit frightening, but how is this Saturday’s Life Hacks?”

    We wanted to set up the “why” before getting to the “how”, because with a big enough “why”, it’s much easier to find the motivation to act on the “how”.

    Test yourself

    Or more conveniently, you and a partner/friend/relative can test each other.

    Simply do like a “blind taste testing”, but for smell. Ideally these will be a range of simple and complex odors, and commercially available smell test kits will provide these, if you don’t want to make do with random items from your kitchen.

    If you’d like to use a clinical diagnostic tool, you can check out:

    Clinical assessment of patients with smell and taste disorders

    …and especially, this really handy diagnostic flowchart:

    Algorithm of evaluation of a patient who has olfactory loss

    Train yourself

    “Olfactory training” has been the got-to for helping people to regain their sense of smell after losing it due to COVID.

    In simple terms, this means simply trying to smell things that “should” have a distinctive odor, and gradually working up one’s repertoire of what one can smell.

    You can get some great tips here:

    AbScent | Useful Insights Into Smell Training

    Hack your training

    An extra trick was researched deeply in a recent study which found that multisensory integration helped a) initially regain the ability to smell things and b) maintain that ability later without the cross-sensory input.

    What that means: you will more likely be able to smell lemon while viewing the color yellow, and most likely of all to be able to smell lemon while actually holding and looking at a slice of lemon. Having done this, you’re more likely to be able to smell (and distinguish) the odor of lemon later in a blind smell test.

    In other words: with this method, you may be able to cut out many months of frustration of trying and failing to smell something, and skip straight to the “re-adding specific smells to my brain’s olfactory database” bit.

  • Relationships: When To Stick It Out & When To Call It Quits

    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.

    Like A Ship Loves An Anchor?

    Today’s article may seem a little bit of a downer to start with, but don’t worry, it picks up again too. Simply put, we’ve written before about many of the good parts of relationships, e.g:

    Only One Kind Of Relationship Promotes Longevity This Much!

    …but what if that’s not what we have?

    Note: if you have a very happy, secure, fulfilling, joyous relationship, then, great! Or if you’re single and happy, then, also great! Hopefully you will still find today’s feature of use if you find yourself advising a friend or family member one day. So without further ado, let’s get to it…

    You may be familiar with the “sunk cost fallacy”; if not: it’s what happens when a person or group has already invested into a given thing, such that even though the thing is not going at all the way they hoped, they now want to continue trying to make that thing work, lest their previous investment be lost. But the truth is: if it’s not going to work, then the initial investment is already lost, and pouring out extra won’t help—it’ll just lose more.

    That “investment” in a given thing could be money, time, energy, or (often the case) a combination of the above.

    In the field of romance, the “sunk cost fallacy” keeps a lot of bad relationships going for longer than perhaps they should, and looking back (perhaps after a short adjustment period), the newly-single person says “why did I let that go on?” and vows to not make the same mistake again.

    But that prompts the question: how can we know when it’s right to “keep working on it, because relationships do involve work”, as perfectly reasonable relationship advice often goes, and when it’s right to call it quits?

    Should I stay or should I go?

    Some questions for you (or perhaps a friend you might find yourself advising) to consider:

    • What qualities do you consider the most important for a partner to have—and does your partner have them?
    • If you described the worst of your relationship to a close friend, would that friend feel bad for you?
    • Do you miss your partner when they’re away, or are you glad of the break? When they return, are they still glad to see you?
    • If you weren’t already in this relationship, would you seek to enter it now? (This takes away sunk cost and allows a more neutral assessment)
    • Do you feel completely safe with your partner (emotionally as well as physically), or must you tread carefully to avoid conflict?
    • If your partner decided tomorrow that they didn’t want to be with you anymore and left, would that be just a heartbreak, or an exciting beginning of a new chapter in your life?
    • What things would you generally consider dealbreakers in a relationship—and has your partner done any of them?

    The last one can be surprising, by the way. We often see or hear of other people’s adverse relationship situations and think “I would never allow…” yet when we are in a relationship and in love, there’s a good chance that we might indeed allow—or rather, excuse, overlook, and forgive.

    And, patience and forgiveness certainly aren’t inherently bad traits to have—it’s just good to deploy them consciously, and not merely be a doormat.

    Either way, reflect (or advise your friend/family member to reflect, as applicable) on the “score” from the above questions.

    • If the score is good, then maybe it really is just a rough patch, and the tools we link at the top and bottom of this article might help.
    • If the score is bad, the relationship is bad, and no amount of historic love or miles clocked up together will change that. Sometimes it’s not even anyone’s fault; sometimes a relationship just ran its course, and now it’s time to accept that and turn to a new chapter.

    “At my age…”

    As we get older, it’s easy for that sunk cost fallacy to loom large. Inertia is heavy, the mutual entanglement of lives is far-reaching, and we might not feel we have the same energy for dating that we did when we were younger.

    And there may sometimes be a statistical argument for “sticking it out” at least for a while, depending on where we are in the relationship, per this study (with 165,039 participants aged 20–76), which found:

    ❝Results on mean levels indicated that relationship satisfaction decreased from age 20 to 40, reached a low point at age 40, then increased until age 65, and plateaued in late adulthood.

    As regards the metric of relationship duration, relationship satisfaction decreased during the first 10 years of the relationship, reached a low point at 10 years, increased until 20 years, and then decreased again.❞

    ~ Dr. Janina Bühler et al.

    Source: Development of Relationship Satisfaction Across the Life Span: A Systematic Review and Meta-Analysis

    And yet, when it comes to prospects for a new relationship…

    • If our remaining life is growing shorter, then it’s definitely too short to spend in an unhappy relationship
    • Maybe we really won’t find romance again… And maybe that’s ok, if w’re comfortable making our peace with that and finding joy in the rest of life (this widowed writer (hi, it’s me) plans to remain single now by preference, and her life is very full of purpose and beauty and joy and yes, even love—for family, friends, etc, plus the memory of my wonderful late beloved)
    • Nevertheless, the simple fact is: many people do find what they go on to describe as their best relationship yet, late in life ← this study is with a small sample size, but in this case, even anecdotal evidence seems sufficient to make the claim reasonable; probably you personally know someone who has done so. If they can, so can you, if you so wish.
    • Adding on to that last point… Later life relationships can also offer numerous significant advantages unique to such (albeit some different challenges too—but with the right person, those challenges are just a fun thing to tackle together). See for example:

    An exploratory investigation into dating among later‐life women

    And about those later-life relationships that do work? They look like this:

    “We’ve Got This”: Middle-Aged and Older (ages 40–87) Couples’ Satisfying Relationships and We-Talk Promote Better Physiological, Relational, and Emotional Responses to Conflict

    this one looks like the title says it all, but it really doesn’t, and it’s very much worth at least reading the abstract, if not the entire paper—because it talks a lot about the characteristics that make for happy or unhappy relationships, and the effect that those things have on people. It really is very good, and quite an easy read.

  • Walnuts 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 walnuts to cashews, we picked the walnuts.

    Why?

    It was close! In terms of macros, walnuts have about 2x the fiber, while cashews have slightly more protein. In the specific category of fats, walnuts have more fat. Looking further into it: walnuts’ fats are mostly polyunsaturated, while cashews’ fats are mostly monounsaturated, both of which are considered healthy.

    Notwithstanding being both high in calories, neither nut is associated with weight gain—largely because of their low glycemic indices (of which, walnuts enjoy the slightly lower GI, but both are low-GI foods)

    When it comes to vitamins, walnuts have more of vitamins A, B2, B3 B6, B9, and C, while cashews have more of vitamins B1, B5, E, and K. Because of the variation in their respective margins of difference, this is at best a moderate victory for walnuts, though.

    In the category of minerals, cashews get their day, as walnuts have more calcium and manganese, while cashews have more copper, iron, magnesium, phosphorus, potassium, selenium, and zinc.

    In short: unless you’re allergic, we recommend enjoying both of these nuts (and others) for a full range of benefits. However, if you’re going to pick one, walnuts win the day.
