Why Do We Have Crooked Teeth When Our Ancestors Didn’t?

Evidence shows that people in ancient times typically had straight teeth set well into strong jaws, with even wisdom teeth fitting properly.

So, what went wrong? Did evolution do us a disservice?

Some information to chew on

Transition from hard-to-chew diets to processed, refined foods over millennia has reduced jaw size while tooth size stayed constant. Smaller jaws lead to tooth crowding, crookedness, and impacted wisdom teeth, requiring braces or extractions in modern times.

However, all is not lost!

Studies on non-human animals show softer diets reduce jaw and facial growth, causing dental crowding. In other words: dental crowding is primarily attributed to dietary and lifestyle changes, though genetics may play a role.

And notably, when it comes to humans, populations with less processed diets experience fewer dental problems, suggesting lifestyle modifications could help prevent tooth crowding.

And no, it is not too late. Remember, you are rebuilding your body all the time, including your bones!

  • Indistractable – by Nir Eyal

    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.

    Have you ever felt that you could accomplish anything you wanted/needed, if only you didn’t get distracted?

    This book lays out a series of psychological interventions for precisely that aim, and it goes a lot beyond the usual “download/delete these apps to help you stop checking social media every 47 seconds”.

    Some you’ll have heard of before, some you won’t have, and if even one method works for you, it’ll have been well worth your while reading this book. This reviewer, for example, enjoyed the call to identity-based strength, e.g. adopting an “I am indistractable*” perspective going into tasks. This is akin to the strength of, for example, “I don’t drink” over “I am a recovering alcoholic”.

    *the usual spelling of this, by the way, is “undistractable”, but we use the author’s version here for consistency. It’s a great marketing gimmick, as all searches for the word “indistractable” will bring up his book.

    Nor is the book just about maximizing productivity to the detriment of everything else; this is not about having a 25 hours per day “grindset”. Rather, it even makes sure to cover such things as focusing on one’s loved ones, for instance.

    Bottom line: if you’ve tried blocking out the distractions but still find you can’t focus, this book offers next-level solutions

  • Why You Can’t Deep Squat (And the Benefits You’re Missing)

    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.

    Matt Hsu fought his own battle with chronic pain from the age of 16 in his feet, knees, hips, back, shoulders, elbows, forearms, wrists, hands, and head. Seeking answers, he’s spent a career in corrective exercise, posture alignment, structural integration, orthopedic exercise, sports medicine, and has more certifications than we care to list. In short, he knows his stuff.

    Yes you can (with some work)

    The deep squat, also called Asian squat, Slav squat, sitting squat, resting squat, primal squat, and various other names, is an important way of sitting that has implications for a lot of aspects of health.

    Why it’s so important: it preserves the mobility of our hips, ankles, and everything in between, and maintaining especially the hip mobility makes a big difference not only to general health, but also to reducing the risk of injury. It also maintains lower body strength, making falls in older age less likely in the first place, and if falls do happen, makes injury less likely, and if injury does happen, makes the injury likely less severe.

    An important misconception: there is a popular, but unfounded, belief that the ability or inability to do this is decided by genes—or if not outright decided, that at the very least Asians and Slavs have a genetic advantage. However, this is simply not true. Westerners and others can learn to do it just fine, and on the flipside, Asians and Slavs who grew up in the West may often struggle with it. The truth is, the deciding factor is lifestyle: if your culture involves sitting this way more often, you’ll be able to do it more comfortably and easily than if you’re just now trying it for the first time.

    Factors that you can control: you can’t change where you grew up, but you can change how you sit down now. Achieving the squat requires repeated position practice, and the more frequently you do so (even if you just start with a few seconds and work your way up to longer periods), the better you’ll get at it. And, on the contrary, sitting in chairs weakens and shortens the muscles involved, so any time you spend sitting in chairs is working against you. There are many reasons it’s advisable to avoid sitting in chairs more than necessary, and this is one of them.

    10almonds tip: a limiting factor for many people initially is ankle flexibility, which may result in one’s center of gravity being a bit far back, leading to a tendency to have to change something to avoid toppling over backwards. Rather than holding onto something immobile (e.g. furniture) in front of where you are sitting, consider simply holding an object in front of you in your hands. A book is a fine example; holding that in front of you (feel free to read the book) will shift your center of gravity forwards a bit, and will thus allow you to sit there a little longer, thus improving your strength and flexibility while you do, until you can do it without holding something in front of you. If you try with a book and you’re still prone to toppling backwards, try with something heavier, but do use the minimum weight necessary, because ultimately the counterbalance is just a crutch to get you to where you need to be.

  • Smarter Tomorrow – by Elizabeth Ricker

    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.

    Based heavily in hard science, with more than 450 citations in over 300 pages, the exhortation is not just “trust me, lol”.

    Instead, she encourages the reader to experiment. Not like “try this and see if it works”, but “here’s how to try this, using scientific method with good controls and good record-keeping”.

    The book is divided into sections, each with a projection of time required at the start and a summary at the end. The reading style is easy-reading throughout, without sacrificing substance.

    It proposes seven key interventions. If just one works for you, it’ll be worth having bought and read the book. More likely most if not all will… Because that’s how science works.

    The Stress Prescription (Against Aging!)

    This is Dr. Elissa Epel, whose work has for the past 20 years specialized in the effect of stress on aging. She’s led groundbreaking research on cortisol, telomeres, and telomerase, all in the context of aging, especially in women, as well as the relationship between stress and weight gain. She was elected member of the National Academy of Medicine for her work on stress pathways, and has been recognized as a key “Influencer in Aging” by the Alliance for Aging Research.

    Indeed, she’s also been named in the top 0.1% of researchers globally, in terms of publication impact.

    What’s that about stress and aging?

    In her words,

    ❝Women with the highest levels of perceived stress have telomeres shorter on average by the equivalent of at least one decade of additional aging compared to low stress women❞

    Source: Accelerated telomere shortening in response to life stress

    We say “in her words”, as she is the top-listed author on this paper—an honour reserved for the lead researcher of any given study/paper.

    However, we’d be remiss not to note that the second-listed author is Nobel Prize Laureate Dr. Elizabeth Blackburn. What a team! Maybe we’ll do a spotlight feature on Dr. Blackburn’s work one of these days, but for now, back to Dr. Epel…

    What does she want us to do about it?

    She has the following advice for us:

    Let go of what we can’t control

    This one is simple enough, and can be as simple as learning how to set anxiety aside, and taking up the practice of radical acceptance of what we cannot control.

    Be challenged, not afraid

    This is about eustress, and being the lion, not the gazelle. Dr. Epel uses the example of how when lions are hunting gazelles, both are stressed, but both are feeling the physiological effects of that stress in terms of the augmentation to their immediate abilities, but only one of them is suffering by it.

    We’ll let her explain how to leverage this:

    TED ideas | Here’s how you can handle stress like a lion, not a gazelle | Dr. Elissa Epel

    Build resilience through controlled discomfort

    Don’t worry, you don’t have to get chased by lions. A cold shower will do it! This is about making use of hormesis, the body’s ability to build resilience to stressors by small doses of controlled cortisol release—as for example when one undergoes thermal shock, which sounds drastic, but for most people, a cold shower (or even an ice bath) is safe enough.

    You can read more about this here:

    A Cold Shower A Day Keeps The Doctor Away

    Connect with nature

    You don’t have to hug a tree, but you do have get to a natural (or at least, natural-seeming) environment once in a while. Simply put, we did not evolve to be in the urban or even suburban settings where most of us spend most of our time. Getting to be around greenery with at least some kind of regularity is hugely beneficial. It doesn’t have to be a national park; a nice garden or local park can suffice, and potted plants at home are better than nothing. Even spending time in virtual reality “nature” is an option:

    Effect of Virtual Reality on Stress Reduction and Change of Physiological Parameters Including Heart Rate Variability in People With High Stress: An Open Randomized Crossover Trial

    (you can see an example there, of the kind of scenery this study used)

    Breathe deeply, and rest deeply

    Mindful breathing, and good quality sleep, are very strongly evidence-based approaches to reduce stress, for example:

    Practice gratitude to build optimism

    Optimism has a huge positive impact on health outcomes, even when other factors (including socioeconomic factors, pre-existing conditions, and general reasons for one person to be more optimistic than another) are controlled for.

    Read: Optimism and Cause-Specific Mortality: A Prospective Cohort Study

    There are various ways to increase optimism, and practising gratitude is one of them—but that doesn’t necessarily mean abandoning realism, either:

    How To Practise (Non-Toxic) Positivity

    There are other ways too, though, and Dr. Epel discusses some with her friend and colleague, Dr. Elizabeth Blackburn, here:

  • When supplies resume, should governments subsidise drugs like Ozempic for weight loss? We asked 5 experts

    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.

    Hundreds of thousands of people worldwide are taking drugs like Ozempic to lose weight. But what do we actually know about them? This month, The Conversation’s experts explore their rise, impact and potential consequences.

    You’ve no doubt heard of Ozempic but have you heard of Wegovy? They’re both brand names of the drug semaglutide, which is currently in short supply worldwide.

    Ozempic is a lower dose of semaglutide, and is approved and used to treat diabetes in Australia. Wegovovy is approved to treat obesity but is not yet available in Australia. Shortages of both drugs are expected to last throughout 2024.

    Both drugs are expensive. But Ozempic is listed on Australia’s Pharmaceutical Benefits Schedule (PBS), so people with diabetes can get a three-week supply for A$31.60 ($7.70 for concession card holders) rather than the full price ($133.80).

    Wegovy isn’t listed on the PBS to treat obesity, meaning when it becomes available, users will need to pay the full price. But should the government subsidise it?

    Wegovy’s manufacturer will need to make the case for it to be added to the PBS to an independent advisory committee. The company will need to show Wegovy is a safe, clinically effective and cost-effective treatment for obesity compared to existing alternatives.

    In the meantime, we asked five experts: when supplies resume, should governments subsidise drugs like Ozempic for weight loss?

    Four out of five said yes

    This is the last article in The Conversation’s Ozempic series. Read the other articles here.

  • Quinoa vs Couscous – 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 quinoa to couscous, we picked the quinoa.

    Why?

    Firstly, quinoa is the least processed by far. Couscous, even if wholewheat, has by necessity been processed to make what is more or less the same general “stuff” as pasta. Now, the degree to which something has or has not been processed is a common indicator of healthiness, but not necessarily declarative. There are some processed foods that are healthy (e.g. many fermented products) and there are some unprocessed plant or animal products that can kill you (e.g. red meat’s health risks, or the wrong mushrooms). But in this case—quinoa vs couscous—it’s all borne out pretty much as expected.

    For the purposes of the following comparisons, we’ll be looking at uncooked/dry weights.

    In terms of macros, quinoa has a little more protein, slightly lower carbs, and several times the fiber. The amino acids making up quinoa’s protein are also much more varied.

    In the category of vitamins, quinoa has more of vitamins A, B1, B2, B6, and B9, while couscous boasts a little more of vitamins B3 and B5. Given the respective margins of difference, as well as the total vitamins contained, this category is an easy win for quinoa.

    When it comes to minerals, this one’s not even more clear. Quinoa has a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. Couscous, meanwhile has more of just one mineral: sodium. So, maybe not one you want more of.

    All in all, today’s is an easy pick: quinoa!
