Our Verdict

When comparing red bell peppers to tomatoes, we picked the peppers.

Why?

In terms of macronutrients, these two fruits-that-get-used-as-vegetables are similar in most respects; they’re mostly water, negligible protein and fat, similar amounts of carbs, even a similar carb breakdown (mostly fructose and glucose). One thing that does set them apart is that peppers* have about 2x the fiber, which difference results in peppers having the lower Glycemic Index—though tomatoes are quite low in GI too.

*for brevity we’re just going to write “peppers”, but we are still talking about sweet red bell peppers throughout. This is important, as different color peppers have different nutrient profiles.

In the category of vitamins, peppers have much more of vitamins A, B1, B2, B3, B5, B6, B9, C, and E. In contrast, tomatoes have more vitamin K. An easy win for peppers.

When it comes to minerals, the margins are narrower, but peppers have more iron, zinc, and selenium, while tomatoes have more calcium and copper. They’re approximately equal on other minerals they both contain, making this category a slight (3:2) win for peppers.

As for phytochemical benefits, both are good sources of lycopene (both better when cooked) and other carotenes (for example lutein), and both have an array of assorted flavonoids.

All in all, a win for peppers, but both are great!

  • Younger For Life – by Dr. Anthony Youn

    We’ve reviewed anti-aging books before, so what makes this one different? Mostly, it’s the very practical focus.

    Which is not to say there’s not also good science in here; there is. But the focus is on what everything means for the reader, not what happened with a certain cohort of lab mice. Instead, he looks at the causes of aging, the process of aging, and what interventions to implement to address those, and reverse many of them.

    Some parts are more general lifestyle interventions that 10almonds readers will know well already, but other parts are very specific advices, protocols, and regimes; in particular his skincare section is well worth reading. As for nutrition, there’s even a respectable recipes section, so this book does have it all!

    The final section of the book is dedicated to plastic surgeries (the author is a plastic surgeon who believes that most people should not need those, and would do well to stick to the advices in the rest of the book). We suspect this last part of the book will be of least interest to 10almonds readers.

    Bottom line: if you’re of the view that getting older should come with as little as possible physical deterioration along the way, then this book can help a lot with that.

  • How To Grow In Comfort

    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.

    How To Grow (Without Leaving Your Comfort Zone)

    “You have to get out of your comfort zone!” we are told, from cradle to grave.

    When we are young, we are advised (or sometimes more forcefully instructed!) that we have to try new things. In our middle age, we are expected to be the world’s greatest go-getters, afraid of nothing and always pushing limits. And when we are old, people bid us “don’t be such a dinosaur”.

    It is assumed, unquestioned, that growth can only occur through hardship and discomfort.

    But what if that’s a discomforting lie?

    Butler (2023) posited an idea: “We never achieve success faster and with less effort than when we are in our comfort zone”

    Her words are an obvious callback to the ideas of Csikszentmihalyi (1970) in the sense of “flow”, in the sense in which that word is used in psychology.

    Flow is: when a person is in a state of energized focus, full involvement, and enjoyment of an activity.

    As a necessary truth (i.e: a function of syllogistic logic), the conditions of “in a state of flow” and “outside of one’s comfort zone” cannot overlap.

    From there, we can further deduce (again by simple logic) that if flow can be found, and/but cannot be found outside of the comfort zone, then flow can only be found within the comfort zone.

    That is indeed comforting, but what about growth?

    Imagine you’ve never gone camping in your life, but you want to get outside of your comfort zone, and now’s the time to do it. So, you check out some maps of the Yukon, purchase some camping gear, and off you go into the wilderness. In the event that you survive to report it, you will indeed be able to say “it was not comfortable”.

    But, did growth occur? Maybe, but… it’s a folly to say “what doesn’t kill us makes us stronger” as a reason to pursue such things. Firstly, there’s a high chance it may kill us. Secondly, what doesn’t kill us often leaves us incredibly weakened and vulnerable.

    When Hannibal famously took his large army of mostly African mercenaries across the Alps during winter to march on Rome from the other side, he lost most of his men on the way, before proceeding to terrorize Northern Italy convincingly with the small remainder. But! Their hard experience hadn’t made them stronger; it had just removed the weaker soldiers, making the resultant formations harder to break.

    All this to say, please do not inflict hardship and discomfort and danger in the hopes it’ll make you stronger; it will probably do the opposite.

    But…

    If, instead of wilderness trekking in the Yukon…

    • You start off with a camper van holiday, then you’ll be taking a fair amount of your comfort with you. In effect, you will be stretching and expanding your comfort zone without leaving it.
    • Then maybe another year you might try camping in a tent on a well-catered camping site.
    • Later, you might try “roughing it” at a much less well-catered camping site.
    • And so on.

    Congratulations, you have tried new things and undergone growth, taking your comfort zone with you all the way!

    This is more than just “easing yourself into” something

    It really is about taking your comfort with you too. If you want to take up running, don’t ask “how can I run just a little bit first” or “how can I make it easier” (well, feel free to ask those things too, but) ask yourself: how can I bring my comfort with me? Comfortable shoes, perhaps, an ergonomic water bottle, shade for your head, maybe.

    ❝Any fool can rough it, but a good soldier can make himself comfortable in any circumstances❞

    ~ British Army maxim

    This goes for more than just physical stuff, too

    If you want to learn a new skill, the initial learning curve can be anxiety-inducing, especially if you are taking a course and worried about keeping up or “not being good enough”.

    So, “secretly” study in advance, at your leisure, get yourself a head start. Find a degree of comfort in what you’ve learned so far, and then bring that comfort with you into your entry-level course that is now less intimidating.

    Discomfort isn’t a badge of honor (and impedes growth)

    Take that extra rest stop on the highway. Bring your favorite coffee with you. Use that walking stick, if it helps.

    Whatever it takes to bring your comfort with you, bring it.

    Trust us, you’ll get further that way.

  • Never Too Old?

    Age Limits On Exercise?

    In Tuesday’s newsletter, we asked you your opinion on whether we should exercise less as we get older, and got the above-depicted, below-described, set of responses:

    • About 42% said “No, we must keep pushing ourselves, to keep our youth“
    • About 29% said “Only to the extent necessary due to chronic conditions etc”
    • About 29% said “Yes, we should keep gently moving but otherwise take it easier”

    One subscriber who voted for “No, we must keep pushing ourselves, to keep our youth“ wrote to add:

    ❝I’m 71 and I push myself. I’m not as fast or strong as I used to be but, I feel great when I push myself instead of going through the motions. I listen to my body!❞

    ~ 10almonds subscriber

    One subscriber who voted for “Only to the extent necessary due to chronic conditions etc” wrote to add:

    ❝It’s never too late to get stronger. Important to keep your strength and balance. I am a Silver Sneakers instructor and I see first hand how helpful regular exercise is for seniors.❞

    ~ 10almonds subscriber

    One subscriber who voted to say “Yes, we should keep gently moving but otherwise take it easier” wrote to add:

    ❝Keep moving but be considerate and respectful of your aging body. It’s a time to find balance in life and not put yourself into a positon to damage youself by competing with decades younger folks (unless you want to) – it will take much longer to bounce back.❞

    ~ 10almonds subscriber

    These will be important, because we’ll come back to them at the end.

    So what does the science say?

    Endurance exercise is for young people only: True or False?

    False! With proper training, age is no barrier to serious endurance exercise.

    Here’s a study that looked at marathon-runners of various ages, and found that…

    • the majority of middle-aged and elderly athletes have training histories of less than seven years of running
    • there are virtually no relevant running time differences (p<0.01) per age in marathon finishers from 20 to 55 years
    • after 55 years, running times did increase on average, but not consistently (i.e. there were still older runners with comparable times to the younger age bracket)

    See: Performance, training and lifestyle parameters of marathon runners aged 20–80 years: results of the PACE-study

    The researchers took this as evidence of aging being indeed a biological process that can be sped up or slowed down by various lifestyle factors.

    See also:

    Age & Aging: What Can (And Can’t) We Do About It?

    this covers the many aspects of biological aging (it’s not one number, but many!) and how our various different biological ages are often not in sync with each other, and how we can optimize each of them that can be optimized

    Resistance training is for young people only: True or False?

    False! In fact, it’s not only possible for older people, but is also associated with a reduction in all-cause mortality.

    Specifically, those who reported strength-training at least once per week enjoyed longer lives than those who did not.

    You may be thinking “is this just the horse-riding thing again, where correlation is not causation and it’s just that healthier people (for other reasons) were able to do strength-training more, rather than the other way around?“

    …which is a good think to think of, so well-spotted if you were thinking that!

    But in this case no; the benefits remained when other things were controlled for:

    ❝Adjusted for demographic variables, health behaviors and health conditions, a statistically significant effect on mortality remained.

    Although the effects on cardiac and cancer mortality were no longer statistically significant, the data still pointed to a benefit.

    Importantly, after the physical activity level was controlled for, people who reported strength exercises appeared to see a greater mortality benefit than those who reported physical activity alone.❞

    ~ Dr. Jennifer Kraschnewski

    See the study: Is strength training associated with mortality benefits? A 15 year cohort study of US older adults

    And a pop-sci article about it: Strength training helps older adults live longer

    Closing thoughts

    As it happens… All three of the subscribers we quoted all had excellent points!

    Because in this case it’s less a matter of “should”, and more a selection of options:

    • We (most of us, at least) can gain/regain/maintain the kind of strength and fitness associated with much younger people, and we need not be afraid of exercising accordingly (assuming having worked up to such, not just going straight from couch to marathon, say).
    • We must nevertheless be mindful of chronic conditions or even passing illnesses/injuries, but that goes for people of any age
    • We also can’t argue against a “safety first” cautious approach to exercise. After all, sure, maybe we can run marathons at any age, but that doesn’t mean we have to. And sure, maybe we can train to lift heavy weights, but if we’re content to be able to carry the groceries or perhaps take our partner’s weight in the salsa hall (or the bedroom!), then (if we’re also at least maintaining our bones and muscles at a healthy level) that’s good enough already.

    Which prompts the question, what do you want to be able to do, now and years from now? What’s important to you?

    Take care!

    You probably know to avoid blue light before bed, put a curfew on the caffeine, and have fresh bedding. So, what does this book offer that’s new?

    As the subtitle suggests, it’s 21 tips for better sleep, so if even half of them are new, then it’ll still be adding value.

    This is a book review, not a book summary, but to give an idea of the kind of thing you might not already know: there’s a section on bedroom houseplants! For example…

    • Which plants filter the air best according to NASA, rather than “according to tradition”
    • Which plants will thrive in what will hopefully be a cool dark environment
    • Which plants produce oxygen even at night, rather than just during the day

    The writing style is personable without losing clarity or objectivity:

    • We read personal anecdotes, and we read science
    • We get “I tried this”, and we get “this sleep study found such-and-such”
    • We get not just the “what”, but also the “why” and the “how”

    We get the little changes that make a big differencesometimes the difference between something working or not!

    Bottom line: if you’d like to get better sleep and a blue light filter hasn’t wowed you and changed your life, this book will bring your sleep knowledge (and practice) to the next level.

    Yes, yes, we know, unplug once in a while. But what else do this highly-qualified pair of neuroscientists have to offer?

    Rather than being a book for the sake of being a book, with lots of fluff and the usual advice about single-tasking, the authors start with a reframe:

    Neurologically speaking, the hit of dopamine we get when looking for information is the exact same as the hit of dopamine that we, a couple of hundred thousand years ago, got when looking for nuts and berries.

    • When we don’t find them, we become stressed, and search more.
    • When we do find them, we are encouraged and search more nearby, and to the other side of nearby, and near around, to find more.

    But in the case of information (be it useful information or celebrity gossip or anything in between), the Internet means that’s always available now.

    So, we jitter around like squirrels, hopping from one to the next to the next.

    A strength of this book is where it goes from there. Specifically, what evidence-based practices will actually keep our squirrel-brain focused… and which are wishful thinking for anyone who lives in this century.

    Bringing original research from their own labs, as well as studies taken from elsewhere, the authors present a science-based toolkit of genuinely useful resources for actual focus.

    Bottom line: if you think you could really optimize your life if you could just get on track and stay on track, this is the book for you.

  • Science of Stretch – by Dr. Leada Malek

    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 book is part of a “Science of…” series, of which we’ve reviewed some others before (Yoga | HIIT | Pilates), and needless to say, we like them.

    You may be wondering: is this just that thing where a brand releases the same content under multiple names to get more sales, and no, it’s not (long-time 10almonds readers will know: if it were, we’d say so!).

    While flexibility and mobility are indeed key benefits in yoga and Pilates, they looked into the science of what was going on in yoga asanas and Pilates exercises, stretchy or otherwise, so the stretching element was not nearly so deep as in this book.

    In this one, Dr. Malek takes us on a wonderful tour of (relevant) human anatomy and physiology, far deeper than most pop-science books go into when it comes to stretching, so that the reader can really understand every aspect of what’s going on in there.

    This is important, because it means busting a lot of myths (instead of busting tendons and ligaments and things), understanding why certain things work and (critically!) why certain things don’t, how certain stretching practices will sabotage our progress, things like that.

    It’s also beautifully clearly illustrated! The cover art is a fair representation of the illustrations inside.

    Bottom line: if you want to get serious about stretching, this is a top-tier book and you won’t regret it.
