The Longevity Diet – by Dr. Valter Longo

Another book with “The New Science” in its subtitle, so, is this one a new science?

Yes and no; some findings are new, many are not, what really sets this book apart from many of its genre though is that rather than focusing on fighting aging, it focuses on retaining youth. While this may seem like one and the same thing, there is a substantive difference beyond the ideological, which is: while anti-aging research focuses on what causes people to suffer age-related decline and fights each of those things, Dr. Longo’s research focuses on what is predominant in youthful bodies, cells, DNA, and looks to have more of that. Looking in a slightly different place means finding slightly different things, and knowledge is power indeed.

Dr. Longo bases his research and focus on his “5 pillars of longevity”. We’ll not keep them a mystery; they are:

  1. Juventology research
  2. Epidemiology
  3. Clinical studies
  4. Centenarian studies
  5. Study of complex systems

The first there (juventology research) may sound like needless jargon, but it is the counterpoint of the field of gerontology, and is otherwise something that didn’t have an established name.

You may wonder why “clinical studies” gets a separate item when the others already include studies; this is because many studies when it comes to aging and related topics are population-based studies, cohort studies, observational studies, or (as is often the case) multiple of the above at once.

Of course, all this discussion of academia is not itself practical information for the reader (unless we happen to work in the field), but it is interesting and does give confidence in the conclusions upon which the practical parts of the book are based.

And what are they? As the title suggests, it’s about diet, and specifically, it’s about Dr. Longo’s “fast-mimicking diet”, which boasts the benefits of intermittent fasting without intermittent fasting. This hinges, of course, on avoiding metabolic overload, which can be achieved with a fairly simple diet governed by the principles outlined in this book, based on the research referenced.

In the category of subjective criticism, there is quite a bit of fluff, much of it self-indulgently autobiographical and very complimentary, but its presence does not take anything away from the excellent content contained in the book.

Bottom line: if you’d like a fresh perspective on regaining/retaining youthfulness, then this is a great book to read.

  • Professional-Style Dental Cleaning At Home?

    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.

    You know the scene: your dentist is rummaging around inside your mouth with an implement that looks like a medieval torture device; you wince at a sudden sharp pain, only to be told “if you flossed, you wouldn’t be bleeding now”.

    For most of us, going to the dentist isn’t near the top of our “favorite things to do” list, but it is of course a necessity of (healthy) life.

    So, what can we do to minimize suffering in the dentist’s chair?

    First, the basics

    Of course, good oral hygiene is the absolute baseline, but with so many choices out there, which is best? We examined an array of options in this three-part series:

    1. Toothpastes & Mouthwashes: Which Help And Which Harm?
    2. Flossing Without Flossing?
    3. Less Common Oral Hygiene Options ← we recommend the miswak! Not only does it clean the teeth as well as or better than traditional brushing, but also it changes the composition of saliva to improve the oral microbiome, effectively turning your saliva into a biological mouthwash that kills unwanted microbes and is comfortable for the ones that should be there.

    In fact, caring for the composition of one’s saliva, and thus one’s oral microbiome, is so important that we did a main feature on that, a little later:

    Make Your Saliva Better For Your Teeth ← this is especially important if you take any meds that affect the composition of your saliva (scroll down to the table of meds). Your medications’ leaflets won’t tell you that it does that directly, but they will list “dry mouth” as one of the potential side effects (and you’ll probably know if you have a medication that gives you a dry mouth).

    Next, level up

    For this one, we’ll drop some links to some videos we’ve featured (for those who prefer text, worry not, your faithful writer has added text-based overviews):

    Now, that last one sounds slightly more exciting than it is—it is about using chemical processes to gradually lessen the tartar over time, with a six-month timeframe.

    So, what if you want to do one better than that?

    Finally… Buckle up, this one’s fun

    Ok, so “fun” and “dental care” don’t usually go hand-in-hand, and maybe your sense of fun differs from this writer’s, but hey. The thing is, we’re going to get hands-on with dental tools.

    Specifically, these dental tools:

    👆 these are literally the tools this writer has; if you look in the specula (the round mirror bits), you can see the reflection of the fluffy gray bathrobe I was wearing when I took the picture!

    You can get tools like these easily online; here’s an example product on Amazon; do also shop around of course, and we recommend checking the reviews to ensure good quality.

    Writer’s story on why I have these: once upon a time, a wisdom tooth came through at 45°, ploughing through the molar next to it, which then needed removing.

    However, my teeth have the interesting anatomical quirk that I have hooked/barbed roots, which does not make tooth extraction easy; it had to come out sidewise, and the process was somewhat bungled by an inexperienced dental surgeon.

    When the anesthetic wore off, it was the most pain I’ve ever been in in my life.

    After that, I wasn’t a very regular returner to the dentist, and in 2013, I fell into a very deep depression for unrelated reasons, and during that period, I got some plaque/tartar buildup on some of my teeth due to lack of care, that then just stayed until I decided to take care of it more recently, which I am happy to say, I’ve now done (my teeth are the happiest and healthiest they’ve ever been), and I’m going to share how, with you.

    So, here’s how to do it… First, you’ll need those tools, of course.

    You will also want a good quality backlit magnifying mirror. Again, here’s an example product on Amazon ← this is the exact kind this writer has, and it’s very good.

    You may be thinking: “wait a minute, this is scary, those are dangerous and I’m not a dentist!”

    If so, then a few quick things to bear in mind:

    • If you’re not comfortable doing it, don’t do it. As ever, our medical/legal disclaimer applies, and we share information for your interest only, and not as an exhortation to take any particular action. By all means confer with your dentist, too, and see whether they support the idea.
    • These things do look scarier than they are once you get used to them. Do you use metal silverware when eating? Technically you could stab yourself with a fork any time, or damage your teeth with it, but when was the last time you did that?
    • With regard to manual dexterity, if you have the manual dexterity required to paint your nails, floss your teeth, sew by hand, or write with a pen, then you have the manual dexterity to do this, too.

    Now, about the tools:

    • Speculum / magnifying speculum: the one with the mirror. This is useful for looking at the backs of teeth.
    • Tweezers: the one with the gold grip in the photo above. You probably won’t need to use these, but we’re sure you know how to use tweezers in general.
    • Dental explorer: the one with the big wicked-looking hook on one end, and a tiny (almost invisible in the photo) hook on the other end. This is for examining cavities, not for manipulating things. Best leave that to your dentist if you have cavities.
    • Dental pick: this is the one to the right of the dental explorer, and it is for cleaning in the crevices between teeth. One end is quite blunt; the other is pointier, and you can choose which end to use depending on what fits into the shape of the crevice between your teeth.
    • Dental scraper: this is the one with chisel ends. One end curves very slightly to the left, the other, very slightly to the right. This is for ergonomics depending on which hand you’re using, and which side you’re scraping (you’ll become very aware that your teeth, even if they look straight, curve very slightly at the edges.

    You’ll be using these last two for the actual tartar removal, selecting the tool appropriate to cleaning the flat surface of a tooth, or the crevice where the teeth meet (not like flossing! That part, yes, but under no circumstances is this thing going all the way through to the other side, it’s just for getting into to nook that the scraper can’t so easily clean, that’s all).

    A word on using metal against your teeth: a scary prospect, initially! However…

    While steel is indeed harder than the enamel of your teeth, the enamel of your teeth is much harder than the plaque/tartar/calculus that you will be removing. Therefore, the technique to use is very gently scrape, starting as gently as humanly possible until you get a feel for it.

    Unlike the dentist, you will have an advantage here in that you have biofeedback, and bone conduction of the sounds in your mouth, so you can exercise much more restraint than your dentist can. With the correct minimum of pressure, the tool should glide smoothly down enamel, but when it’s scraping tartar, it should make a very fine sandpapery noise.

    This is why “or write with a pen” was one of the skills we mentioned earlier; it’s the same thing; you don’t press with a pen so hard that it goes through the paper, so don’t press so hard with the tool that it damages your enamel, that’s all.

    Because of the differential in hardness between the tartar and the enamel, it’s really very easy to remove the tartar without harming the enamel, provided one is gentle.

    Final word of warning; we’ll repeat: If you’re not comfortable doing it, don’t do it. As ever, our medical/legal disclaimer applies, and we share information for your interest only, and not as an exhortation to take any particular action. By all means confer with your dentist, too, and see whether they support the idea.

    Also, while this kind of cleaning can be done safely at home, we recommend against doing anything more complicated than that.

    See for example: Can You Repair Your Own Teeth At Home? ← the short answer is “no”, or not beyond tooth remineralization, anyway, and kits that say otherwise are potentially misleading, or stop-gap solutions at best.

    One last time: always consult with a professional and get their advice (ours is not advice; it’s just information).

    Take care!

  • Calm Your Inflammation – by Dr. Brenda Tidwell

    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 book starts with an overview of inflammation, both acute and chronic, before diving into how to reduce the latter kind (acute inflammation being usually necessary and helpful, usually fighting disease rather than creating it).

    The advice in the book is not just dietary, and covers lifestyle interventions too, including exercise etc—and how to strike the right balance, since the wrong kind of exercise or too much of it can sabotage our efforts. Similarly, Dr. Tidwell doesn’t just say such things as “manage stress” but also provides 10 ways of doing so, and so forth for other vectors of inflammation-control. She does cover dietary things as well though, including supplements where applicable, and the role of gut health, sleep, and other factors.

    The style of the book is quite entry-level pop-science, designed to be readable and comprehensible to all, without unduly dumbing-down. In terms of hard science or jargon, there are 6 pages of bibliography and 3 pages of glossary, so it’s neither devoid of such nor overwhelmed by it.

    Bottom line: if fighting inflammation is a priority for you, then this book is an excellent primer.

  • Do you have knee pain from osteoarthritis? You might not need surgery. Here’s what to try instead

    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.

    Most people with knee osteoarthritis can control their pain and improve their mobility without surgery, according to updated treatment guidelines from the Australian Commission on Safety and Quality in Health Care.

    So what is knee osteoarthritis and what are the best ways to manage it?

    Pexels/Kindelmedia

    More than 2 million Australians have osteoarthritis

    Osteoarthritis is the most common joint disease, affecting 2.1 million Australians. It costs the economy A$4.3 billion each year.

    Osteoarthritis commonly affects the knees, but can also affect the hips, spine, hands and feet. It impacts the whole joint including bone, cartilage, ligaments and muscles.

    Most people with osteoarthritis have persistent pain and find it difficult to perform simple daily tasks, such as walking and climbing stairs.

    Is it caused by ‘wear and tear’?

    Knee osteoarthritis is most likely to affect older people, those who are overweight or obese, and those with previous knee injuries. But contrary to popular belief, knee osteoarthritis is not caused by “wear and tear”.

    Research shows the degree of structural wear and tear visible in the knee joint on an X-ray does not correlate with the level of pain or disability a person experiences. Some people have a low degree of structural wear and tear and very bad symptoms, while others have a high degree of structural wear and tear and minimal symptoms. So X-rays are not required to diagnose knee osteoarthritis or guide treatment decisions.

    Telling people they have wear and tear can make them worried about their condition and afraid of damaging their joint. It can also encourage them to try invasive and potentially unnecessary treatments such as surgery. We have shown this in people with osteoarthritis, and other common pain conditions such as back and shoulder pain.

    This has led to a global call for a change in the way we think and communicate about osteoarthritis.

    What’s the best way to manage osteoarthritis?

    Non-surgical treatments work well for most people with osteoarthritis, regardless of their age or the severity of their symptoms. These include education and self-management, exercise and physical activity, weight management and nutrition, and certain pain medicines.

    Education is important to dispel misconceptions about knee osteoarthritis. This includes information about what osteoarthritis is, how it is diagnosed, its prognosis, and the most effective ways to self-manage symptoms.

    Health professionals who use positive and reassuring language can improve people’s knowledge and beliefs about osteoarthritis and its management.

    Many people believe that exercise and physical activity will cause further damage to their joint. But it’s safe and can reduce pain and disability. Exercise has fewer side effects than commonly used pain medicines such as paracetamol and anti-inflammatories and can prevent or delay the need for joint replacement surgery in the future.

    Many types of exercise are effective for knee osteoarthritis, such as strength training, aerobic exercises like walking or cycling, Yoga and Tai chi. So you can do whatever type of exercise best suits you.

    Increasing general physical activity is also important, such as taking more steps throughout the day and reducing sedentary time.

    Weight management is important for those who are overweight or obese. Weight loss can reduce knee pain and disability, particularly when combined with exercise. Losing as little as 5–10% of your body weight can be beneficial.

    Pain medicines should not replace treatments such as exercise and weight management but can be used alongside these treatments to help manage pain. Recommended medicines include paracetamol and non-steroidal anti-inflammatory drugs.

    Opioids are not recommended. The risk of harm outweighs any potential benefits.

    What about surgery?

    People with knee osteoarthritis commonly undergo two types of surgery: knee arthroscopy and knee replacement.

    Knee arthroscopy is a type of keyhole surgery used to remove or repair damaged pieces of bone or cartilage that are thought to cause pain.

    However, high-quality research has shown arthroscopy is not effective. Arthroscopy should therefore not be used in the management of knee osteoarthritis.

    Joint replacement involves replacing the joint surfaces with artificial parts. In 2021–22, 53,500 Australians had a knee replacement for their osteoarthritis.

    Joint replacement is often seen as being inevitable and “necessary”. But most people can effectively manage their symptoms through exercise, physical activity and weight management.

    The new guidelines (known as “care standard”) recommend joint replacement surgery only be considered for those with severe symptoms who have already tried non-surgical treatments.

    I have knee osteoarthritis. What should I do?

    The care standard links to free evidence-based resources to support people with osteoarthritis. These include:

    If you have osteoarthritis, you can use the care standard to inform discussions with your health-care provider, and to make informed decisions about your care.

    How patients are seeing their doctor is changing, and that could shape access to and quality of care for decades to come.

    More than 100 million Americans don’t have regular access to primary care, a number that has nearly doubled since 2014. Yet demand for primary care is up, spurred partly by record enrollment in Affordable Care Act plans. Under pressure from increased demand, consolidation, and changing patient expectations, the model of care no longer means visiting the same doctor for decades.

    KFF Health News senior correspondent Julie Appleby breaks down what is happening — and what it means for patients.

  • Be A Plant-Based Woman Warrior – by Jane Esselstyn & Ann Esselstyn

    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.

    Notwithstanding the title, this book is not about being a woman or a warrior, but let us share what one reviewer on Amazon wrote:

    ❝I don’t want to become a plant based woman warrior. The sex change would be traumatic for me. However, as a man who proudly takes ballet classes and Pilates, I am old enough not to worry about stereotypes. When I see a good thing, I am going to use it❞

    The authors, a mother-and-daughter team in their 80s and 50s respectively, do give a focus on things that disproportionally affect women, and rectifying those things with diet, especially in one of the opening chapters.

    Most the book, however, is about preventing/reversing things that can affect everyone, such as heart disease, diabetes, inflammation and the autoimmune diseases associated with such, and cancer in general, hence the dietary advice being good for most people (unless you have an unusually restrictive diet).

    We get an overview of the pantry we should cultivate and curate, as well as some basic kitchen skills that will see us well for the rest of the book, such as how to make oat flour and other similar mini-recipes, before getting into the main recipes themselves.

    About the recipes: they are mostly quite simple, though often rely on having pre-prepared items from the mini-recipes we mentioned earlier. They’re all vegan, mostly but not all gluten-free, whole foods, no added sugar, and as for oil… Well, it seems to be not necessarily oil-free, but rather oil-taboo. You see, they just don’t mention it. For example, when they say to caramelize onions, they say to heat a skillet, and when it is hot, add the onions, and stir until browned. They don’t mention any oil in the ingredients or in the steps. It is a mystery. 10almonds note: we recommend olive oil, or avocado oil if you prefer a milder taste and/or need a higher smoke point.

    Bottom line: the odd oil taboo aside, this is a good book of simple recipes that teaches some good plant-based kitchen skills while working with a healthy, whole food pantry.

    Or at the very least: be a plant-based cook regardless of gender, hopefully without war, and enjoy the additions to your culinary repertoire

  • Demystifying Cholesterol

    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.

    All About Cholesterol

    When it comes to cholesterol, the most common lay understanding (especially under a certain age) is “it’s bad”.

    A more informed view (and more common after a certain age) is “LDL cholesterol is bad; HDL cholesterol is good”.

    A more nuanced view is “LDL cholesterol is established as significantly associated with (and almost certainly a causal factor of) atherosclerotic cardiovascular disease and related mortality in men; in women it is less strongly associated and may or may not be a causal factor”

    You can read more about that here:

    Statins: His & Hers? ← we highly recommend reading this, especially if you are a woman and/or considering/taking statins. To be clear, we’re not saying “don’t take statins!”, because they might be the right medical choice for you and we’re not your doctors. But we are saying: here’s something to at least know about and consider.

    Beyond HDL & LDL

    There is also VLDL cholesterol, which as you might have guessed, stands for “very low-density lipoprotein”. It has a high, unhealthy triglyceride content, and it increases atherosclerotic plaque. In other words, it hardens your arteries more quickly.

    The term “hardening the arteries” is an insufficient descriptor of what’s happening though, because while yes it is hardening the arteries, it’s also narrowing them. Because minerals and detritus passing through in the blood (the latter sounds bad, but there is supposed to be detritus passing through in the blood; it’s got to get out of the body somehow, and it’s off to get filtered and excreted) get stuck in the cholesterol (which itself is a waxy substance, by the way) and before you know it, those minerals and other things have become a solid part of the interior of your artery wall, like a little plastering team came and slapped plaster on the inside of the walls, then when it hardened, slapped more plaster on, and so on. Macrophages (normally the body’s best interior clean-up team) can’t eat things much bigger than themselves, so that means they can’t tackle the build-up of plaque.

    Impact on the heart

    Narrower less flexible arteries means very poor circulation, which means that organs can start having problems, which obviously includes your heart itself as it is not only having to do a harder job to keep the blood circulating through the narrower blood vessels, but also, it is not immune to also being starved of oxygen and nutrients along with the rest of the body when the circulation isn’t good enough. It’s a catch 22.

    What if LDL is low and someone is getting heart disease anyway?

    That’s often a case of apolipoprotein B, and unlike lipoprotein A, which is bound to LDL so usually* isn’t a problem if LDL is in “safe” ranges, Apo-B can more often cause problems even when LDL is low. Neither of these are tested for in most standard cholesterol tests by the way, so you might have to ask for them.

    *Some people, around 1 in 20 people, have hereditary extra risk factors for this.

    What to do about it?

    Well, get those lipids tests! Including asking for the LpA and Apo-B tests, especially if you have a history of heart disease in your family, or otherwise know you have a genetic risk factor.

    With or without extra genetic risks, it’s good to get lipids tests done annually from 40 onwards (earlier, if you have extra risk factors).

    See also: Understanding your cholesterol numbers

    Wondering whether you have an increased genetic risk or not?

    Genetic Testing: Health Benefits & Methods ← we think this is worth doing; it’s a “one-off test tells many useful things”. Usually done from a saliva sample, but some companies arrange a blood draw instead. Cost is usually quite affordable; do shop around, though.

    Additionally, talk to your pharmacist to check whether any of your meds have contraindications or interactions you should be aware of in this regard. Pharmacists usually know contraindications/interactions stuff better than doctors, and/but unlike doctors, they don’t have social pressure on them to know everything, which means that if they’re not sure, instead of just guessing and reassuring you in a confident voice, they’ll actually check.

    Lastly, shocking nobody, all the usual lifestyle medicine advice applies here, especially get plenty of moderate exercise and eat a good diet, preferably mostly if not entirely plant-based, and go easy on the saturated fat.

    Note: while a vegan diet contains zero dietary cholesterol (because plants don’t make it), vegans can still get unhealthy blood lipid levels, because we are animals and—like most animals—our body is perfectly capable of making its own cholesterol (indeed, we do need some cholesterol to function), and it can make its own in the wrong balance, if for example we go too heavy on certain kinds of (yes, even some plant-based) saturated fat.

    Read more: Can Saturated Fats Be Healthy? ← see for example how palm oil and coconut oil are both plant-based, and both high in saturated fat, but palm oil’s is heart-unhealthy on balance, while coconut oil’s is heart-healthy on balance (in moderation).
