Dr. Greger (of “Dr. Greger’s Daily Dozen” fame) outlines for us in cold hard facts and stats what’s most likely to be our cause of death. While this is not a cheery premise for a book, he then sets out to work back from there—what could have prevented those specific things?
Some of the advice is what you might expect: eat green things and whole grains, skip the bacon. Other advice is less well-known: get a daily dose of curcumin/turmeric, take it with black pepper. Works wonders. If you want to add in daily exercises, just lifting the book could be a start; weighing in at 678 pages, it’s an information-dense tome that’s more likely to be sifted through than read cover-to-cover.
If you’re a more cynical sort, you might note that since the book doesn’t confer immortality, but does help us avoid statistically likely causes of death, logically it significantly increases our chances of dying in a statistically unlikely way. (Ha! Your mental exercise for today will be decoding that sentence )

Tartar Removal At Home & How To Prevent Tartar
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.
Three things to bear in mind:
- Tartar is hardened plaque.
- Plaque is an infected biofilm that expands the natural thin film on teeth.
- Healthy biofilm resists plaque and tartar formation.
Therefore, the recommended approach is a multistep program:
The Complete Mouth Care System
Dr. Phillips recommends to use these five products in this order twice daily:
- Zellie’s Mints & Gum: having 6–10 grams of xylitol daily will help to loosen plaque on teeth so that the following program is more effective. Xylitol protects from mouth acidity and help to remineralize teeth.
- CloSYS Prerinse: CloSYS will prepare your teeth for brushing. This pH neutral rinse ensures that brushing teeth does not occur in an acidic mouth and therefore easily damage teeth.
- Crest Cavity Protection Regular Paste: has an active ingredient of sodium fluoride at optimal concentration (not stannous fluoride). This paste has the proper abrasion and no glycerine.
- Listerine: is an effective rinse that targets the bacteria that cause plaque build up and gingivitis with three active ingredients: eucalyptus essential oil, menthol essential oil, and thymol essential oil. As such, unlike many mouthwashes, listerine does not harm the mouth’s diversity of good bacteria or the mouth’s production of nitric oxide.
- ACT Anticavity Rinse: ACT is a very dilute but extremely effective sodium fluoride solution. It helps prevent and reverse cavities, strengthen teeth, reduce sensitivity, and leaves your breath fresh.
She advises us that by doing this twice-daily over 6 months, we can expect significant tartar reduction, and indeed, that dental appointments may reveal minimal or no need for tartar removal.

Is thirst a good predictor of dehydration?
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.
Water is essential for daily functioning and health, and we can only survive a few days without it. Yet we constantly lose water through sweat, urination and even evaporation when we breathe.
This is why we have evolved a way to regulate and maintain water in our bodies. Like other animals, our survival relies on a strong biological drive that tells us to find and drink water to balance fluid loss.
This is thirst – a sensation of dryness in the mouth signalling we need to have a drink. This basic physiological mechanism is controlled mainly by part of the brain’s “control centre”, called the hypothalamus. The hypothalamus receives signals from various regions of the body and in return, releases hormones that act as a messenger to signal the thirst sensation.
KieferPix/Shutterstock What is dehydration?
Staying hydrated (having enough water in our bodies) is important for several reasons, including:
- regulating body temperature through sweat and respiration
- lubricating joints and eyes
- preventing infections
- digesting and absorbing nutrients
- flushing out waste (via the kidneys)
- preventing constipation
- brain function (including memory and concentration)
- mood and energy levels
- physical performance and recovery from exercise
- skin health.
Dehydration occurs when our body doesn’t have enough water. Even slight drops in fluid levels have noticeable consequences, such as headaches, feeling dizzy, lethargy and struggling to concentrate.
Chronic dehydration can pose more serious health risks, including urinary tract infections, constipation and kidney stones.
What does the evidence say?
Despite thirst being one of the most basic biological drivers for good hydration, science suggests our feelings of thirst and subsequent fluid intake don’t always correlate with hydration levels.
For example, a recent study explored the impact of thirst on fluid intake and hydration status. Participants attended a lab in the morning and then later in the afternoon to provide markers of hydration status (such as urine, blood samples and body weight). The relationship between levels of thirst in the morning and afternoon hydration status was negligible.
Further, thirst may be driven by environmental factors, such as access to water. For example, one study looked at whether ample access to water in a lab influenced how much people drank and how hydrated they were. The link between how thirsty they felt and how hydrated they were was weak, suggesting the availability of water influenced their fluid intake more than thirst.
Exercise can also change our thirst mechanism, though studies are limited at this stage.
Being thirsty doesn’t necessarily mean we’re dehydrated. puhhha/Shutterstock Interestingly, research shows women experience thirst more strongly than men, regardless of hydration status. To understand gender differences in thirst, researchers infused men and women with fluids and then measured their thirst and how hydrated they were. They found women generally reported thirst at a lower level of fluid loss. Women have also been found to respond more to feeling thirsty by drinking more water.
Other ways to tell if you need to drink some water
While acknowledging some people will need to drink more or less, for many people, eight cups (or two litres) a day is a good amount of water to aim for.
But beyond thirst, there are many other ways to tell whether you might need to drink more water.
1. urine colour: pale yellow urine typically indicates good hydration, while darker, concentrated urine suggests dehydration
2. frequency of going to the toilet: urinating regularly (around four to six times a day) indicates good hydration. Infrequent urination can signal dehydration
3. skin turgor test: gently pinching the skin (for example, on the back of the hand) and observing how quickly the skin returns to its normal position can help assess hydration. Slow return may indicate dehydration
If skin stays elevated after pinching it may be a sign of dehydration. SusaZoom/Shutterstock 4. mouth and lips: a dry mouth or cracked lips can be early signs of dehydration
5. headaches and fatigue: frequent headaches, dizziness, or unexplained fatigue can be signs of inadequate hydration
6. sweating: in physically active people, monitoring how much they sweat during activity can help estimate fluid loss and hydration needs. Higher levels of sweat may predispose a person to dehydration if they are unable to replace the fluid lost through water intake
These indicators, used together, provide a more comprehensive picture of hydration without solely depending on the sensation of thirst.
Of course, if you do feel thirsty, it’s still a good idea to drink some water.

Biohack Your Way to Healthy Skin – by Jennifer Sun
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 author, an aesthetician with a biotech background, explains about the overlap of skin health and skin beauty, making it better from the inside first (diet and other lifestyle factors), and then tweaking things as desired from the outside.
We previous reviewed another book of hers, “Unleashing Your Best Skin”, and this time the focus is on things you can do at home—not requiring expensive salon treatments (the other book covers both approaches; this one simply skips the clinic work and instead has a lot more detail in the at-home category).
As for what she covers, it comes in categories:
- Gadgets to consider investing in, how to pick good ones, and what gadgets to avoid
- Basic skincare knowledge and practice; here we’re talking cleaners, tonics, moisturizers, and so forth
- Best topical and oral ingredients for the skin (and in contrast, ingredients to be wary of)
- Nutrition for skincare; not just “your skin needs these ingredients”, but also…
- Gut health for skincare, which gets a whole chapter just for that
- Biohacking hormones for skincare, including in the cases of various common hormone imbalances (e.g. menopause, PCOS, etc) and other complications not generally thought of in terms of skincare, such as diabetes and hypo-/hyperthyroidism.
- Circulatory health for skincare (blood and lymph)
- Mental health techniques for skincare (including improving sleep, managing stress, supplements to consider, etc).
As with her other book that we reviewed, the book is broadly aimed at women, and the section on sex-hormonal considerations is completely aimed at women, but as for the rest of the book, there’s no pressing reason why this book couldn’t benefit men too. It also addresses considerations when it comes to darker skintones, something that a lot of similar books overlook.
The style is directly instructional, albeit light and conversational in tone, and still with 20+ pages of scientific references to show that she does indeed know her stuff.
Bottom line: if you’d like to improve your skin health, and/but aren’t a fan of going to the salon, then this book will be an invaluable resource.

Here’s To Getting Assuredly Good 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.
An unusual amount of excitement in the health news world this week, with health insurance in the spotlight:
Deny, Delay, Depose?
Insurance company UnitedHealthcare, which used AI with a 90% error rate to deny insurance claims (of which, disproportionately denying insurance claims of the elderly), has come under extra public scrutiny this week for its recent-years business practices:
❝Nearly 1 in 5 insured adults experienced claim denials during a 12-month period.
Those with job-based insurance or Affordable Care Act policies ran into this problem about twice as often as those covered by Medicare or Medicaid❞
…although, the company has dramatically increased its care denials for Medicare Advantage enrollees, doubling the rate of denials as it implemented its new, automated denials process.
Anesthesiologist Dr. Brain Schmutzler noted:
❝We have a bigger issue with the insurance companies in general, who, essentially, it’s their job to make money, not to actually pay for health care❞
And in those cases where healthcare is not denied, it is often dangerously delayed, as insurance companies can stall for time to decide whether they’re going to pay or not.
One useful take-away from all of this is that if your insurance claim is denied, consider fighting it, as often they can be overturned.
Specifically, it can be good to insist on knowing who (named persons) was involved in the denial process, and their qualifications. Once upon a time, this was mostly unqualified interns, which prompted insurance companies to reverse the denial rather than admit that; nowadays it’s mostly AI, which many companies can hope will shield them from culpability—either way, fighting for one’s rights can often be successful.

Rest Easy
Health insurer Elevance Health (formerly Anthem Blue Cross Blue Shield), had last month announced plans to limit its coverage for anesthesia used in operations, whereby they would pay for only a certain amount of anesthetic, and if the procedure was still ongoing when that amount had been used, then well, you were on your own.
However, on Thursday afternoon and allegedly completely coincidentally in the wake of the Wednesday assassination of the CEO who oversaw the denial of so many health insurance claims, this decision to limit paying for anesthesia was reversed, retracted, and they are now doing their best to downplay what the proposal would have meant for anesthesiologists and patients:

Getting a good grip of your health
What’s the best indicator of good health when it comes to age-related health issues? It’s not BMI! Could it be blood pressure? It could, but the news presently is about grip strength.
While training to have an amazing grip (and neglecting all else) will not necessarily increase your general healthspan, having a weak or strong grip is strongly associated with, respectively, having weak or strong general health in later years.
This is because unless someone has been training very unnaturally, grip strength is a good general measure of overall muscle strength, which in turn is a good indicator of metabolic health, as well as bodily robustness.

Longevity for the Lazy – by Dr. Richard Malish
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.
There are some people who devote all their resources to longevity, which can become a full-time occupation, not to mention a very expensive endeavor. This book’s for those who want to get the best possible “bang for buck” by doing the things that have the most favorable cost:worth ratio.
Dr. Malish covers what can be done easily for personal longevity, as well as what technological advances can be enjoyed that those before us didn’t have as options. He also discusses the diseases that are most likely to kill us, and how to avoid those.
He preaches a proactive approach, but one that is simple and consistent and based in good science, and good statistics. Indeed, while he’s served 20 years as an army doctor and a cardiologist, he now works as a healthcare policy consultant, so he is well-placed to advise.
The style of the book is halfway between regular pop-science and a textbook; you can either read it cover-to-cover, or skim first though the key points, highlight boxes, summaries, and the like. He also provides a time-phased task list, for those who like things to be laid out like that.
Bottom line: this is a very good, methodical guide to living longer without making it a full-time occupation.

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:
