We often write about polyphenols here at 10almonds; sometimes mentioning that a certain food is good because it has them, or else occasionally an entire article about a particular polyphenol. But what about a birds-eye view of polyphenols as a whole?
Well, there are many, but we’ve picked 21 particularly beneficial for human health, and what foods contain them.
We’ll be working from this fantastic database, by the way:
❝Phenol-Explorer is the first comprehensive database on polyphenol content in foods. The database contains more than 35,000 content values for 500 different polyphenols in over 400 foods. These data are derived from the systematic collection of more than 60,000 original content values found in more than 1,300 scientific publications. Each of these publications has been critically evaluated before inclusion in the database. The whole data on the polyphenol composition of foods is available for download.❞

We use this database at least several times per week while writing 10almonds; it’s a truly invaluable resource!
However, 500 is a lot, so here’s a rundown of 21 especially impactful ones; we’ve sorted them per the categories used in the explorer, and in some cases we’ve aggregated several very similar polyphenols typically found together in the same foods, into one item (so for example we just list “quercetin” instead of quercetin 3-O-rutinoside + quercetin 4′-O-glucoside + quercetin 3,4′-O-diglucoside, etc etc). We’ve also broadly grouped some particularly populous ones such as “anthocyanins”, “catechins”, and so forth.

Why Everyone You Don’t Like Is A Narcissist
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.
We’ve written before about how psychiatry tends to name disorders after how they affect other people, rather than how they affect the bearer, and this is most exemplified when it comes to personality disorders. For example:
“You have a deep insecurity about never being good enough, and you constantly mess up in your attempt to overcompensate? You may have Evil Bastard Disorder!”
“You have a crippling fear of abandonment and that you are fundamentally unloveable, so you do all you can to try to keep people close? You must have Manipulative Bitch Disorder!”
See also: Miss Diagnosis: Anxiety, ADHD, & Women
Antisocial DiagnosesThese days, it is easy to find on YouTube countless videos of how to spot a narcissist, with a list of key traits that all mysteriously describe exactly the exes of everyone in the comments.
And these days it is mostly “narcissist”, because “psychopath” and “sociopath” have fallen out of popular favor a bit:
- perhaps for coming across as overly sensationalized, and thus lacking credibility
- perhaps because “Narcissistic Personality Disorder (NPD)” exists in the DSM-5 (the US’s latest “Diagnostic and Statistical Manual of Mental Disorders”), while psychopathy and sociopathy are not mentioned as existing.
You may be wondering: what do “psychopathy” and “sociopathy” mean?
And the answer is: they mean whatever the speaker wants them to mean. Their definitions and differences/similarities have been vigorously debated by clinicians and lay enthusiasts alike for long enough that the scientific world has pretty much given up on them and moved on.
Stigma vs pathology
Because of the popular media (and social media) representation of NPD, it is easy to armchair diagnose one’s relative/ex/neighbor/in-law/boss/etc as being a narcissist, because the focus is on “narcissists do these bad things that are mean to people”.
If the focus were instead on “narcissists have cripplingly low self-esteem, and are desperate to not show weakness in a world they have learned is harsh and predatory”, then there may not be so many armchair diagnoses—or at the very least, the labels may be attached with a little more compassion, the same way we might with other mental health issues such as depression.
Not that those with depression get an easy time of it socially either—society’s response is generally some manner of “aren’t you better yet, stop being lazy”—but at the very least, depressed people are not typically viewed with hatred.
A quick aside: if you or someone you know is struggling with depression, here are some things that actually help:
The Mental Health First-Aid You’ll Hopefully Never Need
The disorder is not the problem
Maybe your relative, ex, neighbor, etc really is clinically diagnosable as a narcissist. There are still two important things to bear in mind:
- After centuries of diagnosing people with mental health maladies that we now know don’t exist per se (madness, hysteria, etc), and in recent decades countless revisions to the DSM and similar tomes, thank goodness we now have the final and perfect set of definitions that surely won’t be re-written in the next few years or so ← this is irony; it will absolutely be re-written numerous times yet because of course it’s still not a magically perfect descriptor of the broad spectrum of human nature
- The disorder is not the problem; the way they treat (or have treated) you is the problem.
For example, let’s take a key thing generally attributed to narcissists: a lack of empathy
Now, empathy can be divided into:
- affective empathy: the ability to feel what other people are feeling
- cognitive empathy: the ability to intellectually understand what other people are feeling (akin to sympathy, which is the same but with the requisite of having experienced the thing in question oneself)
A narcissist (as well as various other people without NPD) will typically have negligible affective empathy, and their cognitive empathy may be a little sluggish too.
Sluggish = it may take them a beat longer than most people, to realize what an external signifier of emotions means, or correctly guess how something will be felt by others. This can result in gravely misspeaking (or inappropriately emoting), after failing to adequately quickly “read the room” in terms of what would be a socially appropriate response. To save face, they may then either deny/minimize the thing they just said/did, or double-down on it and go on [what for them feels like] the counterattack.
As to why this shutting off of empathy happens: they have learned that the world is painful, and that people are sources of pain, and so—to avoid further pain—have closed themselves off to that, often at a very early age. This will also apply to themselves; narcissists typically have negligible self-empathy too, which is why they will commonly make self-destructive decisions, even while trying to put themselves first.
Important note on how this impacts other people: the “Golden Rule” of “treat others as you would wish to be treated” becomes intangible, as they have no more knowledge of their own emotional needs than they do of anyone else’s, so cannot make that comparison.
Consider: if instead of being blind to empathy, they were colorblind… You would probably not berate them for buying green apples when you asked for red. They were simply incapable of seeing that, and consequently made a mistake. So it is when it’s a part of the brain that’s not working normally.
So… Since the behavior does adversely affect other people, what can be done about it? Even if “hate them for it and call for their eradication from the face of the Earth” is not a reasonable (or compassionate) option, what is?
Take the bull by the horns
Above all, and despite all appearances, a narcissist’s deepest desire is simply to be accepted as good enough. If you throw them a life-ring in that regard, they will generally take it.
So, communicate (gently, because a perceived attack will trigger defensiveness instead, and possibly a counterattack, neither of which are useful to anyone) what behavior is causing a problem and why, and ask them to do an alternative thing instead.
And, this is important, the alternative thing has to be something they are capable of doing. Not merely something that you feel they should be capable of doing, but that they are actually capable of doing.
- So not: “be a bit more sensitive!” because that is like asking the colorblind person to “be a bit more observant about colors”; they are simply not capable of it and it is folly to expect it of them, because no matter how hard they try, they can’t.
- But rather: “it upsets me when you joke about xyz; I know that probably doesn’t make sense to you and that’s ok, it doesn’t have to. I am asking, however, if you will please simply refrain from joking about xyz. Would you do that for me?”
Presented with such, it’s much more likely that the narcissist will drop their previous attempt to be good enough (by joking, because everyone loves someone with a sense of humor, right?) for a new, different attempt to be good enough (by showing “behold, look, I am a good person and doing the thing you asked, of which I am capable”).
That’s just one example, but the same methodology can be applied to most things.

Eat to Beat Disease – by Dr. William Li
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.
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.

Kidney Beans vs Fava Beans – 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 kidney beans to fava beans, we picked the kidney beans.
Why?
It’s a simple and straightforward one today!
The macronutrient profiles are mostly comparable, but kidney beans do have a little more protein and a little more fiber.
In the category of vitamins, kidney beans have more of vitamins B1, B5, B6, B9, C, E, & K, while fava beans boast only more of vitamins B2 and B3. They are both equally good sources of choline, but the general weight of vitamins is very much in kidney beans’ favor, with a 7:2 lead, most of which have generous margins.
When it comes to minerals, kidney beans have more iron, phosphorus, and potassium, while fava beans have more copper and selenium. They’re both equally good sources of other minerals they both contain. Still, a 3:2 victory for kidney beans on the mineral front.
Adding up the moderate victory on macros, the strong victory on vitamins, and the slight victory on minerals, all in all makes for a clear win for kidney beans.
Still, enjoy both! Diversity is healthy.

How Jumping Rope Changes The Human Body
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 popularly enjoyed by professional boxers and six-year-old girls, jumping rope is one of the most metabolism-boosting exercises around:
Just a hop, skip, and a jump away from good health
Maybe you haven’t tried it since your age was in single digits, so, if you do…
What benefits can you expect?
- Improves cardiovascular fitness, equivalent to 30 minutes of running with just 10 minutes of jumping.
- Increases bone density and boosts immunity by aiding the lymphatic system.
- Enhances explosiveness in the lower body, agility, and stamina.
- Improves shoulder endurance, coordination, and spatial awareness.
What kind of rope is best for you?
- Beginner ropes: licorice ropes (nylon/vinyl), beaded ropes for rhythm and durability.
- Advanced ropes: speed ropes (denser, faster materials) for higher speeds and more difficult skills.
- Weighted ropes: build upper body muscles (forearms, shoulders, chest, back).
What length should you get?
- Recommended rope length varies by height (8 ft for 5’0″–5’4″, 9 ft for 5’5″–5’11”, 10 ft for 6’0″ and above).
- Beginners should start with longer ropes for clearance.
What should you learn?
- Initial jump rope skills: start with manageable daily jump totals, gradually increasing as ankles, calves, and feet adapt.
- Further skills: learn the two-foot jump and then the boxer’s skip for efficient, longer sessions and advanced skills. Keep arms close and hands at waist level for a smooth swing.

Yoga for Better Sleep – by Mark Stephens
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 has, as you might expect:
- postural exercises
- breathing exercises
- meditation exercises
Instructions given in all of the above categories are clear and easy to follow, and there are photographic illustrations too where appropriate.
What sets it apart from many books of this kind is that it also has chapters dedicated to various specific circumstances; the many actual reasons people seriously struggle to sleep; not just “screentime too late”, but for example deprepression, sleep apnea, hyperarousal, or even just aging.
As well as the comprehensive exercises, there are also many tips, tricks, hacks, and workarounds—it’s a practical guidebook with practical advice.
While the book is about yogic practices, the author also does tackle this holistically, acknowledging that there are many factors going on, and that yogic practices should be one more string to our sleep-improving bow—as we continue with other general good advice for good sleep too, have medical tests if it seems appropriate, that kind of thing. Basically, to have one’s assorted approaches work together with synergistic effect.
Bottom line: this book will quite possibly put you to sleep! But only in the best possible way.

What Nobody Teaches You About Strengthening Your Knees
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.
Strengthening unhappy knees can seem difficult, because many obvious exercises like squats may hurt, and can feel like they are doing harm (and if your knees are bad enough, maybe they are; it depends on many factors). Here’s a way to improve things:
The muscle nobody talks about
Well, not nobody. But, it’s a muscle that’s rarely talked about; namely, the tibialis anterior.
It plays a key role in decelerating knee motion—in other words, the movement that hurts if you have bad knees. It’s essential for absorbing shock during activities like walking, climbing stairs, and stepping off curbs
So, of course, strengthening this muscle supports knee health.
The exercise this video recommends for strengthening it involves leaning against a wall with feet about a foot away (closer feet make it easier, further makes it harder). Note, this is a lean, not a “Roman chair”.
The exercise involves squeezing the quadriceps, lifting toes toward the nose, and engaging the tibialis anterior muscle. If you’re wondering what to do with your hands, they can be held out with palms open to work on posture, or hanging by the sides. Do this for about 1½–2 minutes.
