The Dental Diet – by Dr. Steven Lin

As it turns out, there’s a lot more to healthy teeth than skipping the sugar and getting some calcium.

The author’s journey started with the realization that most of his work as a dentist should be unnecessary, and not just in the “you should have been flossing” sense. Rather, he came to the same conclusions as his fellow dentist Weston Price before him, and this time (unlike Price) he stuck to his own field, dentistry—meaning that the conclusions he kept were the more valid ones.

Another thing he does better than Price is that he contextualizes the information—we don’t need, for example, to be eating seal fat as a main component of our diet, but we do need to be getting sufficient amounts of certain fat-soluble vitamins. And most people aren’t. Same with what’s good or bad for our oral microbiome, and by extension, our saliva, and by extension, our teeth and gums.

There’s a lot of nutritional information in here; macros and micronutrients alike, but the book goes further than that, to also recommend minimally-processed food that requires more chewing, for example. Not just for its nutritional content, but because that helps our teeth move to (and then stay) where they are ideally supposed to be. No amount of perfectly-blended nutritional supplement drink will align your maxilla for you, say. But chomping on raw carrots? Different story.

Dr. Lin offers a 40-day meal plan, but aware that if you’re vegetarian or vegan you’re probably going to have to rethink it yourself using the information he gives, because his meal plan includes animal products.

Bottom line: if you’d like to eat for better oral health (nutritionally, physically, and for your oral microbiome), this book has all the information you’ll need.

  • Healthy Longevity As A Lifestyle Choice

    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.

    7 Keys To Healthy Longevity

    This is Dr. Luigi Fontana. He’s a research professor of Geriatrics & Nutritional Science, and co-director of the Longevity Research Program at Washington University in St. Louis.

    What does he want us to know?

    He has a many-fold approach to healthy longevity, most of which may not be news to you, but you might want to prioritize some things:

    Consider caloric restriction with optimal nutrition (CRON)

    This is about reducing the metabolic load on your body, which frees up bodily resources for keeping yourself young.

    Keeping your body young and healthy is your body’s favorite thing to do, but it can’t do that if it never gets a chance because of all the urgent metabolic tasks you’re giving it.

    If CRON isn’t your thing (isn’t practicable for you, causes undue suffering, etc) then intermittent fasting is a great CR mimetic, and he recommends that too. See also:

    Keep your waistline small

    Whichever approach you prefer to use to look after your metabolic health, keeping your waistline down is much more important for health than BMI.

    Specifically, he recommends keeping it:

    • under 31.5” for women
    • under 37” for men

    The disparity here is because of hormonal differences that influence both metabolism and fat distribution.

    Exercise as part of your lifestyle

    For Dr. Fontana, he loves mountain-biking (this writer could never!) and weight-lifting (also not my thing). But what’s key is not the specifics, but what’s going on:

    • Some kind of frequent movement
    • Some kind of high-intensity interval training
    • Some kind of resistance training

    Frequent movement because our bodies are evolved to be moving more often than not:

    The Doctor Who Wants Us To Exercise Less, & Move More

    High-Intensity Interval Training because unlike most forms of exercise (which slow metabolism afterwards to compensate), it boosts metabolism for up to 2 hours after training:

    How To Do HIIT (Without Wrecking Your Body)

    Resistance training because strength (of muscles and bones) matters too:

    Resistance Is Useful! (Especially As We Get Older)

    Writer’s examples:

    So while I don’t care for mountain-biking or weight-lifting, what I do is:

    1) movement: walk (briskly!) everywhere and also use a standing desk
    2) HIIT: 2-minute bursts of hindu squats and/or exercise bike sprints
    3) resistance: pilates and other calisthenics

    Moderation is not key

    Dr. Fontana advises that we do not smoke, and that we do not drink alcohol, for example. He also notes that just as the only healthy amount of alcohol is zero, less ultra-processed food is always better than more.

    Maybe you don’t want to abstain completely, but mindful wilful consumption of something unhealthy is preferable to believing “moderate consumption is good for the health” and an unhealthy habit develops!

    Greens and beans

    Shocking absolutely nobody, Dr. Fontana advocates for (what has been the most evidence-based gold standard of healthy-aging diets for quite some years now) the Mediterranean diet.

    See also: Four Ways To Upgrade The Mediterranean Diet ← this is about tweaking the Mediterranean diet per personal area of focus, e.g. anti-inflammatory bonus, best for gut, heart healthiest, and most neuroprotective.

    Take it easy

    Dr. Fontana advises us (again, with a wealth of evidence) Mindfulness-Based Stress Reduction, and to get good sleep.

    Not shocked?

    To quote the good doctor,

    ❝There are no shortcuts. No magic pills or expensive procedures can replace the beneficial effects of a healthy diet, exercise, mindfulness, or a regenerating night’s sleep.❞

    Always a good reminder!

  • World Menopause Day Health News Round-Up

    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.

    In order to provide variety in this week’s round-up, not all of this is menopause-related, but it is all important:

    Menopause & CVD

    Untreated menopause is associated with higher incidence of heart disease, and higher mortality. People often forget about how much estrogen does for us (well, for those of us with a physiology running on estrogen, anyway; gentlemen, your testosterone is fine for you), and think it is “just” a sex hormone, but it’s a lot more.

    Read in full: Menopause transition linked to increased heart disease risk

    Related: What Menopause Does To The Heart

    Extraterrestrial medical technology

    The much lower gravity in Earth orbit has allowed for tissue engineering techniques that Earth’s normal gravity imposes limitations on. This is big news, because it means that rather than replacing a whole liver, tissue implants could be grafted, allowing the extant liver to repair itself (something livers are famously good at, but they need enough undamaged base material to work with).

    Read in full: How liver tissue from the International Space Station may transform tissue engineering

    Related: How To Unfatty A Fatty Liver

    One thing and then another

    As if endometriosis weren’t unpleasant enough in and of itself, the endothelial dysfunction inherent to it also raises cardiovascular disease risk. This is important, because while endometriosis has (like many maladies predominantly affecting women) generally been shrugged off by the medical world as an unhappy inconvenience but not life-threatening, now we know it comes with extra existential risks too:

    Read in full: Understanding cardiovascular risks in endometriosis patients

    Related: What You Need To Know About Endometriosis

    Push-button meditation

    Unlike mindfulness meditation, listening to music is a very passive experience, and thus requires less effort from the user. And yet, it has been associated with lower perceived pain levels, lower self-reported anxiety levels, less opioid use, and measurably lower heart-rate.

    Read in full: Listening to music may speed up recovery from surgery, research suggests

    Related: Nobody Likes Surgery, But Here’s How To Make It Much Less Bad

    Cholesterol in menopause: quality over quantity

    Much like previous research has shown that the quantity of LDL is not nearly so predictive of health outcomes in women as it is in men, this study into HDL and menopausal women shows that quantity of HDL does not matter nearly so much as the quality of it.

    Read in full: HDL quality, not quantity, contribute to the first sign of Alzheimer’s disease in women

    Related: Statins: His & Hers? ← consistent with the above, statins (to lower LDL cholesterol) generally help more for men and produce more adverse side effects for women. So again, a case of “the actual amount of cholesterol isn’t so important for women as for men”.

  • How Beneficial Is MCT Oil, Really?

    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.

    Often derived from coconuts (though it doesn’t have to be), medium-chain triglycerides (MCTs) are trendy… But does the science back the hype?

    First, the principle

    MCTs are commonly enjoyed because unlike short- or long-chain fatty acids, they can be quickly broken down and either immediately converted quickly and easily into energy, or turned into ketones in the case of a surplus (in the case of true excess, however, it’ll simply be stored as fat).

    Most of that involves the liver, so for anyone who wants a refresher on liver health:

    How To Unfatty A Fatty Liver ← notwithstanding the title, this is also important knowledge even if your liver is healthy now—if you’d like it to stay healthy, anyway!

    You can also read about the ins and outs of glycogen metabolism and the body’s energy-based metabolic processes in general (including the body’s energy processes that go on in the liver), here:

    From Apples to Bees, and High-Fructose Cs: Which Sugars Are Healthier, And Which Are Just The Same?

    If the liver turns the MCTs into ketones, those ketones will then be used for energy if there is insufficient glucose available (as the body will always use glucose from the blood first, if available, before moving to alternative energy sources such as ketones and/or fat reserves.)

    Thus, many people look to ketones as a solution for having enough energy to function while on a very low-carb diet such as the ketogenic diet:

    Ketogenic Diet: Burning Fat Or Burning Out?

    …which as you’ll recall, does work for short-term weight loss, but brings long-term health risks, so should not be undertaken for long periods of time.

    So, does MCT Oil help?

    With regard to weight loss, the research is weak and mixed:

    • Weak, because often the methodology was shoddy, often there are many factors not controlled-for, and often the sample sizes were small (and also, RCTs by their very nature tend to be quite short-term (often 6, 8, or 12 weeks), whereas heavy reliance on ketones from MCTs may fall into the same long-term problems as the ketogenic diet in general).
    • Mixed, because the results varied widely (probably because of the aforementioned problems).

    Rather than pick at individual studies, let’s look at this review and meta-analysis of 13 studies, with a combined sample size of 749 people (so you can imagine how small the individual RCTs were):

    ❝Compared with LCTs, MCTs decreased body weight (-0.51 kg [95% CI-0.80 to -0.23 kg]; P<0.001; I(2)=35%); waist circumference (-1.46 cm [95% CI -2.04 to -0.87 cm]; P<0.001; I(2)=0%), hip circumference (-0.79 cm [95% CI -1.27 to -0.30 cm]; P=0.002; I(2)=0%), total body fat (standard mean difference -0.39 [95% CI -0.57 to -0.22]; P<0.001; I(2)=0%), total subcutaneous fat (standard mean difference -0.46 [95% CI -0.64 to -0.27]; P<0.001; I(2)=20%), and visceral fat (standard mean difference -0.55 [95% CI -0.75 to -0.34]; P<0.001; I(2)=0%).

    No differences were seen in blood lipid levels.

    Many trials lacked sufficient information for a complete quality assessment, and commercial bias was detected.❞

    So, if we’re going to take those numbers at face value, that means a net weight loss, over the course of the trial period, was…

    *drumroll*

    0.51kg (that’s about 1 lb).

    To put that into perspective, if you did nothing else but pee 1 cup of urine before getting weighed, you’d register as having lost 0.25kg (or about ½ lb) by virtue of the bathroom trip alone.

    Here’s the paper:

    Effects of medium-chain triglycerides on weight loss and body composition: a meta-analysis of randomized controlled trials

    What about cholesterol and heart health?

    With regard to cholesterol, MCT oil is touted as improving blood lipids, which means lowering LDL and increasing HDL (within a safe range, anyway).

    You’ll remember that the above review concluded “No differences were seen in blood lipid levels”.

    It may again be a case of individual studies cancelling each other out. For example…

    This study found that it improved lipids in 40 young women as part of a calorie-controlled interventional diet:

    Effects of dietary coconut oil on the biochemical and anthropometric profiles of women presenting abdominal obesity

    This study found that it worsened lipids in 17 young men, worse even than taking an equivalent amount of sunflower oil:

    Effects of medium-chain fatty acids and oleic acid on blood lipids, lipoproteins, glucose, insulin, and lipid transfer protein activities

    In short, it’s a gamble.

    It may be good for insulin sensitivity, though

    This one seems to be specific to people with type 2 diabetes. The paper heading says it all, but we include the link in case you want to know the details (the short version is, it improved insulin sensitivity in diabetic subjects only (not others), and didn’t affect anything else that was measured:

    Dietary substitution of medium-chain triglycerides improves insulin-mediated glucose metabolism in NIDDM subjects

    The sample size was small (20 people total, of whom 10 had diabetes), and the next study was with 40 people, this time moderately overweight and all with type 2 diabetes:

    Effects of dietary medium-chain triglyceride on weight loss and insulin sensitivity in a group of moderately overweight free-living type 2 diabetic Chinese subjects

  • How light can shift your mood and mental 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.

    This is the next article in our ‘Light and health’ series, where we look at how light affects our physical and mental health in sometimes surprising ways. Read other articles in the series.

    It’s spring and you’ve probably noticed a change in when the Sun rises and sets. But have you also noticed a change in your mood?

    We’ve known for a while that light plays a role in our wellbeing. Many of us tend to feel more positive when spring returns.

    But for others, big changes in light, such as at the start of spring, can be tough. And for many, bright light at night can be a problem. Here’s what’s going on.

    llaszlo/Shutterstock

    An ancient rhythm of light and mood

    In an earlier article in our series, we learned that light shining on the back of the eye sends “timing signals” to the brain and the master clock of the circadian system. This clock coordinates our daily (circadian) rhythms.

    “Clock genes” also regulate circadian rhythms. These genes control the timing of when many other genes turn on and off during the 24-hour, light-dark cycle.

    But how is this all linked with our mood and mental health?

    Circadian rhythms can be disrupted. This can happen if there are problems with how the body clock develops or functions, or if someone is routinely exposed to bright light at night.

    When circadian disruption happens, it increases the risk of certain mental disorders. These include bipolar disorder and atypical depression (a type of depression when someone is extra sleepy and has problems with their energy and metabolism).

    Light on the brain

    Light may also affect circuits in the brain that control mood, as animal studies show.

    There’s evidence this happens in humans. A brain-imaging study showed exposure to bright light in the daytime while inside the scanner changed the activity of a brain region involved in mood and alertness.

    Another brain-imaging study found a link between daily exposure to sunlight and how the neurotransmitter (or chemical messenger) serotonin binds to receptors in the brain. We see alterations in serotonin binding in several mental disorders, including depression.

    What happens when the seasons change?

    Light can also affect mood and mental health as the seasons change. During autumn and winter, symptoms such as low mood and fatigue can develop. But often, once spring and summer come round, these symptoms go away. This is called “seasonality” or, when severe, “seasonal affective disorder”.

    What is less well known is that for other people, the change to spring and summer (when there is more light) can also come with a change in mood and mental health. Some people experience increases in energy and the drive to be active. This is positive for some but can be seriously destabilising for others. This too is an example of seasonality.

    Most people aren’t very seasonal. But for those who are, seasonality has a genetic component. Relatives of people with seasonal affective disorder are more likely to also experience seasonality.

    Seasonality is also more common in conditions such as bipolar disorder. For many people with such conditions, the shift into shorter day-lengths during winter can trigger a depressive episode.

    Counterintuitively, the longer day-lengths in spring and summer can also destabilise people with bipolar disorder into an “activated” state where energy and activity are in overdrive, and symptoms are harder to manage. So, seasonality can be serious.

    Alexis Hutcheon, who experiences seasonality and helped write this article, told us:

    […] the season change is like preparing for battle – I never know what’s coming, and I rarely come out unscathed. I’ve experienced both hypomanic and depressive episodes triggered by the season change, but regardless of whether I’m on the ‘up’ or the ‘down’, the one constant is that I can’t sleep. To manage, I try to stick to a strict routine, tweak medication, maximise my exposure to light, and always stay tuned in to those subtle shifts in mood. It’s a time of heightened awareness and trying to stay one step ahead.

    So what’s going on in the brain?

    One explanation for what’s going on in the brain when mental health fluctuates with the change in seasons relates to the neurotransmitters serotonin and dopamine.

    Serotonin helps regulate mood and is the target of many antidepressants. There is some evidence of seasonal changes in serotonin levels, potentially being lower in winter.

    Dopamine is a neurotransmitter involved in reward, motivation and movement, and is also a target of some antidepressants. Levels of dopamine may also change with the seasons.

    But the neuroscience of seasonality is a developing area and more research is needed to know what’s going on in the brain.

    How about bright light at night?

    We know exposure to bright light at night (for instance, if someone is up all night) can disturb someone’s circadian rhythms.

    This type of circadian rhythm disturbance is associated with higher rates of symptoms including self-harm, depressive and anxiety symptoms, and lower wellbeing. It is also associated with higher rates of mental disorders, such as major depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder (or PTSD).

    Why is this? Bright light at night confuses and destabilises the body clock. It disrupts the rhythmic regulation of mood, cognition, appetite, metabolism and many other mental processes.

    But people differ hugely in their sensitivity to light. While still a hypothesis, people who are most sensitive to light may be the most vulnerable to body clock disturbances caused by bright light at night, which then leads to a higher risk of mental health problems.

    Bright light at night disrupts your body clock, putting you at greater risk of mental health issues. Ollyy/Shutterstock

    Where to from here?

    Learning about light will help people better manage their mental health conditions.

    By encouraging people to better align their lives to the light-dark cycle (to stabilise their body clock) we may also help prevent conditions such as depression and bipolar disorder emerging in the first place.

    Healthy light behaviours – avoiding light at night and seeking light during the day – are good for everyone. But they might be especially helpful for people at risk of mental health problems. These include people with a family history of mental health problems or people who are night owls (late sleepers and late risers), who are more at risk of body clock disturbances.

  • Four Ways To Upgrade The Mediterranean Diet

    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.

    Four Ways To Upgrade The Mediterranean Diet

    The Mediterranean Diet is considered by many to be the current “gold standard” of healthy eating, and with good reason. With 10,000+ studies underpinning it and counting, it has a pretty hefty weight of evidence.

    (For contrast, the Ketogenic Diet for example has under 5,000 studies at time of writing, and many of those include mentioning the problems with it. That’s not to say the Keto is without its merits! It certainly can help achieve some short term goals, but that’s a topic for another day)

    Wondering what the Mediterranean Diet consists of? We outlined it in a previous main feature, so here it is for your convenience 😎

    To get us started today, we’ll quickly drop some links to a few of those Mediterranean Diet studies from the top:

    The short version is: it glows, in a good way.

    The anti-inflammatory upgrade

    One thing about the traditional Mediterranean Diet is… where are the spices?!

    A diet focusing on fruits and non-starchy vegetables, healthy oils and minimal refined carbs, can be boosted by adding uses of spices such as chili, turmeric, cumin, fenugreek, and coriander:

    The gut-healthy upgrade:

    The Mediterranean Diet already gives for having a small amount of dairy, mostly in the form of cheeses, but this can be tweaked:

    Mediterranean diet with extra dairy could be a gut gamechanger

    The heart-healthy upgrade

    The Mediterranean Diet is already highly recommended for heart health, and it offers different benefits to different parts of cardiovascular health:

    The Mediterranean Diet: its definition and evaluation of a priori dietary indexes in primary cardiovascular prevention

    The DASH (Dietary Approaches to Stop Hypertension) diet can boost it further, specifically in the category of, as the name suggests, lowering blood pressure.

    It’s basically the Mediterranean Diet with a few tweaks. Most notably, red meat no longer features (the Mediterranean Diet allows for a small amount of red meat), and fish has gone up in the list:

    Description of the DASH Eating Plan

    The brain-healthy upgrade:

    The MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet combines several elements from the above, as the name suggests. It also adds extra portions of specific brain-foods, that already exist in the above diets, but get a more substantial weighting in this one:
