Dr. William Li asks the important question: is your diet feeding disease, or defeating it?
Because everything we put in our bodies makes our health just a little better—or just a little worse. Ok, sometimes a lot worse.
But for most people, when it comes to diet, it’s a death of a thousand cuts of unhealthy food. And that’s what he looks to fix with this book.
The good news: Dr. Li (while not advocating for unhealthy eating, of course), focuses less on what to restrict, and more on what to include. This book covers hundreds of such healthy foods, and ideas (practical, useful ones!) on incorporating them daily, including dozens of recipes.
He mainly looks at five ways our food can help us with…
- Angiogenesis (blood vessel replacement)
- Regeneration (of various bodily organs and systems)
- Microbiome health (and all of its knock-on effects)
- DNA protection (and thus slower cellular aging)
- Immunity (defending the body while also reducing autoimmune problems)
The style is simple and explanatory; Dr. Li is a great educator. Reading this isn’t a difficult read, but you’ll come out of it feeling like you just did a short course in health science.
Bottom line: if you’d like an easy way to improve your health in an ongoing and sustainable way, then this book can help you do just that.

Hate salad or veggies? Just keep eating them. Here’s how our tastebuds adapt to what we eat
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.
Do you hate salad? It’s OK if you do, there are plenty of foods in the world, and lots of different ways to prepare them.
But given almost all of us don’t eat enough vegetables, even though most of us (81%) know eating more vegetables is a simple way to improve our health, you might want to try.
If this idea makes you miserable, fear not, with time and a little effort you can make friends with salad.
Why don’t I like salads?
It’s an unfortunate quirk of evolution that vegetables are so good for us but they aren’t all immediately tasty to all of us. We have evolved to enjoy the sweet or umami (savoury) taste of higher energy foods, because starvation is a more immediate risk than long-term health.
Vegetables aren’t particularly high energy but they are jam-packed with dietary fibre, vitamins and minerals, and health-promoting compounds called bioactives.
Those bioactives are part of the reason vegetables taste bitter. Plant bioactives, also called phytonutrients, are made by plants to protect themselves against environmental stress and predators. The very things that make plant foods bitter, are the things that make them good for us.
Unfortunately, bitter taste evolved to protect us from poisons, and possibly from over-eating one single plant food. So in a way, plant foods can taste like poison.
For some of us, this bitter sensing is particularly acute, and for others it isn’t so bad. This is partly due to our genes. Humans have at least 25 different receptors that detect bitterness, and we each have our own genetic combinations. So some people really, really taste some bitter compounds while others can barely detect them.
This means we don’t all have the same starting point when it comes to interacting with salads and veggies. So be patient with yourself. But the steps toward learning to like salads and veggies are the same regardless of your starting point.
It takes time
We can train our tastes because our genes and our receptors aren’t the end of the story. Repeat exposures to bitter foods can help us adapt over time. Repeat exposures help our brain learn that bitter vegetables aren’t posions.
And as we change what we eat, the enzymes and other proteins in our saliva change too. This changes how different compounds in food are broken down and detected by our taste buds. How exactly this works isn’t clear, but it’s similar to other behavioural cognitive training.
Add masking ingredients
The good news is we can use lots of great strategies to mask the bitterness of vegetables, and this positively reinforces our taste training.
Salt and fat can reduce the perception of bitterness, so adding seasoning and dressing can help make salads taste better instantly. You are probably thinking, “but don’t we need to reduce our salt and fat intake?” – yes, but you will get more nutritional bang-for-buck by reducing those in discretionary foods like cakes, biscuits, chips and desserts, not by trying to avoid them with your vegetables.
Adding heat with chillies or pepper can also help by acting as a decoy to the bitterness. Adding fruits to salads adds sweetness and juiciness, this can help improve the overall flavour and texture balance, increasing enjoyment.
Pairing foods you are learning to like with foods you already like can also help.
The options for salads are almost endless, if you don’t like the standard garden salad you were raised on, that’s OK, keep experimenting.
Experimenting with texture (for example chopping vegetables smaller or chunkier) can also help in finding your salad loves.
Challenge your biases
Challenging your biases can also help the salad situation. A phenomenon called the “unhealthy-tasty intuition” makes us assume tasty foods aren’t good for us, and that healthy foods will taste bad. Shaking that assumption off can help you enjoy your vegetables more.
When researchers labelled vegetables with taste-focused labels, priming subjects for an enjoyable taste, they were more likely to enjoy them compared to when they were told how healthy they were.
The bottom line
Vegetables are good for us, but we need to be patient and kind with ourselves when we start trying to eat more.
Try working with biology and brain, and not against them.
And hold back from judging yourself or other people if they don’t like the salads you do. We are all on a different point of our taste-training journey.

Fixing Fascia
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.
Fascia: Why (And How) You Should Take Care Of Yours
Fascia is the web-like layer of connective tissue that divides your muscles and organs from each other. It simultaneously holds some stuff in place, and allows other parts to glide over each other with minimal friction.
At least, that’s what it’s supposed to do.
Like any body part, it can go wrong. More on this later. But first…
A quick note on terms
It may seem like sometimes people say “myofascial” because it sounds fancier, but it does actually have a specific meaning too:
- “Fascia” is what we just described above
- “Myofascial” means “of or relating to muscles and fascia”
For example, “myofascial release” means “stopping the fascia from sticking to the muscle where it shouldn’t” and “myofascial pain” means “pain that has to do with the muscles and fascia”. See also:
Myofascial vs Fascia: When To Use Each One? What To Consider
Why fascia is so ignored
For millennia, it was mostly disregarded as a “neither this nor that” tissue that just happens to be in the body. We didn’t pay attention to it, just like we mostly don’t pay attention to the air around us.
But, much like the air around us, we sure pay attention when something goes wrong with it!
However, even in more recent years, we’ve been held back until quite new developments like musculoskeletal ultrasound that could show us problems with the fascia.
What can go wrong
It’s supposed to be strong, thin, supple, and slippery. It holds on in the necessary places like a spiderweb, but for the most part, it is evolved for minimum friction.
Some things can cause it to thicken and become sticky in the wrong places. Things such as:
- Physical trauma, e.g. an injury or surgery—but we repeat ourselves, because a surgery is an injury! It’s a (usually) necessary injury, but an injury nonetheless.
- Compensation for pain. If a body part hurts for some reason, and your posture changes to accommodate that, doing so can mess up your fascia, and cause you different problems somewhere else entirely.
- This is not witchcraft; think of how, when using a corded vacuum cleaner, sometimes the cord can get snagged on something in the next room and we nearly break something because we expected it to just come with us and it didn’t? It’s like that.
- Repetitive movements (repetitive strain injury is partly a myofascial issue)
- Not enough movement: when it comes to range of motion, it’s “use it or lose it”.
- The human body tries its best to be as efficient as possible for us! So eventually it will go “Hey, I notice you never move more than 30º in this direction, so I’m going to stop making fascia that allows you to go past that point, and I’ll just dump the materials here instead”
“I’ll just dump the materials here instead” is also part of the problem—it creates what we colloquially call “knots”, which are not so much part of the muscle as the fascia that covers it. That’s an actual physical sticky lumpy bit.
What to do about it
Firstly, avoid the above things! But, if for whatever reason something has gone wrong and you now have sticky lumpy fascia that doesn’t let you move the way you’d like (if you have any mobility/flexibility issues that aren’t for another known reason, then this is usually it), there are things can be done:
- Heat—is definitely not a cure-all, but it’s a good first step before doing the other things. A heating pad or a warm bath are great.
- Here’s an example of a neck+back+shoulders heating pad; you can get them for different body parts, or just use an electric blanket!
- Massage—ideally, by someone else who knows what they are doing. Self-massage is possible, as is teaching oneself (there are plenty of video tutorials available), but skilled professional therapeutic myofascial release massage is the gold standard.
- Foam rollers are a great no-skill way to get going with self-massage, whether because that’s what’s available to you, or because you just want something you can do between sessions. Here’s an example of the kind we mean.
- Acupuncture—triggering localized muscular relaxation, an important part of myofascial release, is something acupuncture is good at.
- See also: Pinpointing The Usefulness Of Acupuncture ← noteworthily, the strongest criticism of acupuncture for pain relief is that it performs only slightly better than sham acupuncture, but taken in practical terms, all that really means is “sticking little needles in does work, even if not necessarily by the mechanism acupuncturists believe”
- Calisthenics—Pilates, yoga, and other forms of body movement training can help gradually get one’s fascia to where and how it’s supposed to be.
- This is that “use it or lose it” bodily efficiency we talked about!
Remember, the body is always rebuilding itself. It never stops, until you die. So on any given day, you get to choose whether it rebuilds itself a little bit worse or a little bit better.
Take care!

Physical Sunscreen or Chemical Sunscreen – 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 physical sunscreens to chemical sunscreens, we picked the physical sunscreens.
Why?
It’s easy to vote against chemical sunscreens, because it has “chemical” in the name, which tends to be offputting PR-wise no matter how healthy something is.
But in this case, there’s actual science here too!
Physical sunscreens physically block the UV rays.
- On the simplest of levels, mud is a physical sunscreen, as you can see widely used by elephants, hippos, pigs, and other animals.
- On a more sophisticated level, modern physical sunscreens often use tiny zinc particles (or similar) to block the UV rays in a way that isn’t so obvious to the naked eye—so we can still see our skin, and it looks just like we applied an oil or other moisturizer.
Chemical sunscreens interact with the UV rays in a way that absorbs them.
- Specifically, they usually convert it into relatively harmless thermal energy (heat)
- However, this can cause problems if there’s too much heat!
- Additionally, chemical sunscreens can get “used up” in a way that physical sunscreens can’t* becoming effectively deactivated once the chemical reaction has run its course and there is no more reagent left unreacted.
- Worse, some of the reagents, when broken down by the UV rays, can potentially cause harm when absorbed by the skin.
*That said, physical sunscreens will still need “topping up” because we are a living organism and our body can’t resist redistributing and using stuff—plus, depending on the climate and our activities, we can lose some externally too.

How To Kill Laziness
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.
Laziness Is A Scooby-Doo Villain.
Which means: to tackle it requires doing a Scooby-Doo unmasking.
You know, when the mystery-solving gang has the “ghost” or “monster” tied to a chair, and they pull the mask off, to reveal that there was no ghost etc, and in fact it was a real estate scammer or somesuch.
Social psychologist Dr. Devon Price wrote about this (not with that metaphor though) in a book we haven’t reviewed yet, but will one of these days:
Laziness Does Not Exist – by Dr. Devon Price (book)
In the meantime, and perhaps more accessibly, he gave a very abridged summary for Medium:
Medium | Laziness Does Not Exist… But unseen barriers do (11mins read)
Speaking of barriers, Medium added a paywall to that (the author did not, in fact, arrange the paywall as Medium claim), so in case you don’t have an account, he kindly made the article free on its own website, here:
Devon Price | Laziness Does Not Exist… But unseen barriers do (same article; no paywall)
He details problems that people get into (ranging from missed deadlines to homelessness), that are easily chalked up to laziness, but in fact, these people are not lazily choosing to suffer, and are usually instead suffering from all manner of unchosen things, ranging from…
- imposter syndrome / performance anxiety,
- perfectionism (which can overlap a lot with the above),
- social anxiety and/or depression (these also can overlap for some people),
- executive dysfunction in the brain, and/or
- just plain weathering “the slings and arrows of outrageous fortune [and] the heartache and the thousand natural shocks that flesh is heir to”, to borrow from Shakespeare, in ways that aren’t always obviously connected—these things can be great or small, it could be a terminal diagnosis of some terrible disease, or it could be a car breakdown, but the ripples spread.
And nor are you, dear reader, choosing to suffer (even if sometimes it appears otherwise)
Unless you’re actually a masochist, at least, in which case, you do you. But for most of us, what can look like laziness or “doing it to oneself” is usually a case of just having one or more of the above-mentioned conditions in place.
Which means…
That grace we just remembered above to give to other people?
Yep, we should give that to ourselves too.
Not as a free pass, but in the same way we (hopefully) would with someone else, and ask: is there some problem I haven’t considered, and is there something that would make this easier?
Here are some tools to get you started:

5 Surprising Benefits Of Exercise After 50 (More Than Just Fitness)
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.
It’s easy to want to do less as we get older, but the benefits of continuing to actively exercise, pushing oneself even just a little, can be far-reaching.
Direct and indirect benefits
As well as the obvious fitness benefits, keeping up good levels of exercise can also offer:
Healthy Skin
Exercise improves circulation, bringing growth factors (thus: regeneration, because it’s replacing cells), oxygen, and nutrients to the skin. Accordingly, it can lead to healthier, more youthful-looking skin as a low-cost alternative to a lot of skincare products. That said, it also encourages good skin habits, like daily sunscreen use.
Bone Health
Weight-bearing and resistance exercises (which between them, encompasses most forms of exercise) improve bone density. This is because physical stress signals bones to strengthen, reducing the risk of fractures. This includes activities like walking, hiking, and using resistance bands or weights. Note however that it is on a “per bone” basis. So for example, hiking will improve your lower body and spine, but do nothing for your arms. On the other hand, doing a daily groceries trip on foot, if local geography makes that practicable, can do the whole body, if one is then carrying groceries home (this writer lives about 2 miles from where she buys groceries, and does this pretty much daily).
Mental Health
Exercise, especially outdoors, has well-established positive effects on mental well-being, and can relieve stress and improve mood. As a bonus, community engagement and shared experiences can enhance mental health benefits for many people—but if you prefer it as peaceful time for yourself, that’s beneficial in its own way too!
Better Sleep
Physical activity helps promote better sleep quality, which is important for so many aspects of health—because fatiguing the body through exercise can lead to a more restful night, which is often harder to achieve with age.
Visibility and Confidence
Staying active and taking on challenges (e.g. training for some event) can boost visibility in social and family settings, countering “invisibility” often felt from midlife onwards. And even if one doesn’t do those things, exercise fosters confidence and helps people carry themselves with more self-assurance, which has a lot of knock-on benefits too.

Grains: Bread Of Life, Or Cereal Killer?
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.
Going Against The Grain?
In Wednesday’s newsletter, we asked you for your health-related opinion of grains (aside from any gluten-specific concerns), and got the above-depicted, below-described, set of responses:
- About 69% said “They are an important cornerstone of a healthy balanced diet”
- About 22% said “They can be enjoyed in moderation, but watch out”
- About 8% said “They are terrible health-drainers that will kill us”
So, what does the science say?
They are terrible health-drainers that will kill us: True or False?
True or False depending on the manner of their consumption!
There is a big difference between the average pizza base and a bowl of oats, for instance. Or rather, there are a lot of differences, but what’s most critical here?
The key is: refined and ultraprocessed grains are so inferior to whole grains as to be actively negative for health in most cases for most people most of the time.
But! It’s not because processing is ontologically evil (in reality: some processed foods are healthy, and some unprocessed foods are poisonous). although it is a very good general rule of thumb.
So, we need to understand the “why” behind the “key” that we just gave above, and that’s mostly about the resultant glycemic index and associated metrics (glycemic load, insulin index, etc).
In the case of refined and ultraprocessed grains, our body gains sugar faster than it can process it, and stores it wherever and however it can, like someone who has just realised that they will be entertaining a houseguest in 10 minutes and must tidy up super-rapidly by hiding things wherever they’ll fit.
And when the body tries to do this with sugar from refined grains, the result is very bad for multiple organs (most notably the liver, but the pancreas takes quite a hit too) which in turn causes damage elsewhere in the body, not to mention that we now have urgently-produced fat stored in unfortunate places like our liver and abdominal cavity when it should have gone to subcutaneous fat stores instead.
In contrast, whole grains come with fiber that slows down the absorption of the sugars, such that the body can deal with them in an ideal fashion, which usually means:
- using them immediately, or
- storing them as muscle glycogen, or
- storing them as subcutaneous fat
👆 that’s an oversimplification, but we only have so much room here.
For more on this, see:
Glycemic Index vs Glycemic Load vs Insulin Index
And for why this matters, see:
Which Sugars Are Healthier, And Which Are Just The Same?
And for fixing it, see:
They can be enjoyed in moderation, but watch out: True or False?
Technically True but functionally False:
- Technically true: “in moderation” is doing a lot of heavy lifting here. One person’s “moderation” may be another person’s “abstemiousness” or “gluttony”.
- Functionally false: while of course extreme consumption of pretty much anything is going to be bad, unless you are Cereals Georg eating 10,000 cereals each day and being a statistical outlier, the issue is not the quantity so much as the quality.
Quality, we discussed above—and that is, as we say, paramount. As for quantity however, you might want to know a baseline for “getting enough”, so…
They are an important cornerstone of a healthy balanced diet: True or False?
True! This one’s quite straightforward.
3 servings (each being 90g, or about ½ cup) of whole grains per day is associated with a 22% reduction in risk of heart disease, 5% reduction in all-cause mortality, and a lot of benefits across a lot of disease risks:
❝This meta-analysis provides further evidence that whole grain intake is associated with a reduced risk of coronary heart disease, cardiovascular disease, and total cancer, and mortality from all causes, respiratory diseases, infectious diseases, diabetes, and all non-cardiovascular, non-cancer causes.
These findings support dietary guidelines that recommend increased intake of whole grain to reduce the risk of chronic diseases and premature mortality.❞
~ Dr. Dagfinn Aune et al.
We’d like to give a lot more sources for the same findings, as well as papers for all the individual claims, but frankly, there are so many that there isn’t room. Suffice it to say, this is neither controversial nor uncertain; these benefits are well-established.
Here’s a very informative pop-science article, that also covers some of the things we discussed earlier (it shows what happens during refinement of grains) before getting on to recommendations and more citations for claims than we can fit here:
Harvard School Of Public Health | Whole Grains
“That’s all great, but what if I am concerned about gluten?”
There certainly are reasons you might be, be it because of a sensitivity, allergy, or just because perhaps you’d like to know more.
Let’s first mention: not all grains contain gluten, so it’s perfectly possible to enjoy naturally gluten-free grains (such as oats and rice) as well as gluten-free pseudocereals, which are not actually grains but do the same job in culinary and nutritional terms (such as quinoa and buckwheat, despite the latter’s name).
Finally, if you’d like to know more about gluten’s health considerations, then check out our previous mythbusting special:
