21 Most Beneficial Polyphenols & What Foods Have Them
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 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.
Without further ado, here’s what you ideally want to be getting plenty of in your diet:

Herring vs Sardines – 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 herring to sardine, we picked the sardines.
Why?
In terms of macros, they are about equal in protein and fat, but herring has about 2x the saturated fat and about 2x the cholesterol. So, sardines win this category easily.
When it comes to vitamins, herring has more of vitamins B1, B2, B6, B9, and B12, while sardines have more of vitamins B3, E, and K. That’s a 5:3 win for herring, although it’s worth mentioning that the margins of difference are mostly not huge, except for that sardines have 26x the vitamin K content. Still, by the overall numbers, this one’s a win for herring.
In the category of minerals, herring is not richer in any minerals*, while sardines are richer in calcium, copper, iron, manganese, phosphorus, and selenium, meaning a clear win for sardines.
*unless we want to consider mercury to be a mineral, in which case, let’s mention that on average, herring is 6x higher in mercury. However, we consider that also a win for sardines.
All in all, sardines are better for the heart (much lower in cholesterol), bones (much higher in calcium), and brain (much lower in mercury).

The Procrastination Cure – by Jeffery Combs
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.
Why do we procrastinate? It’s not usually because we are lazy, and in fact we can often make ourselves very busy while procrastinating. And at some point, the bad feelings about procrastinating become worse than the experience of actually doing the thing. And still we often procrastinate. So, why?
Jeffery Combs notes that the reasons can vary, but generally fall into six mostly-distinct categories. He calls them:
- The neurotic perfectionist
- The big deal chaser
- The chronic worrier
- The rebellious rebel
- The drama addict
- The angry giver
These may overlap somewhat, but the differences are important when it comes to differences of tackling them.
Giving many illustrative examples, Combs gives the reader all we’ll need to know which category (or categories!) we fall into.
Then, he draws heavily on the work of Dr. Albert Ellis to find ways to change the feelings that we have that are holding us back.
Those feelings might be fear, shame, resentment, overwhelm, or something else entirely, but the tools are in this book.
A particular strength of this book is that it takes an approach that’s essentially Rational Emotive Behavior Therapy (REBT) repackaged for a less clinically-inclined audience (Combs’ own background is in marketing, not pyschology). Thus, for many readers, this will tend to make the ideas more relatable, and the implementations more accessible.
Bottom line: if you’ve been meaning to figure out how to beat your procrastination, but have been putting it off, now’s the time to do it.

Are You Stuck Playing These Three Roles in Love?
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 psychology of Transactional Analysis holds that our interpersonal dynamics can be modelled in the following fashion:
The roles
- Child: vulnerable, trusting, weak, and support-seeking
- Parent: strong, dominant, responsible—but also often exhausted and critical
- Adult: balanced, thoughtful, creative, and kind
Ideally we’d be able to spend most of our time in “Adult” mode, and occasionally go into “Child” or “Parent” mode when required, e.g. child when circumstances have rendered us vulnerable and we need help; parent when we need to go “above and beyond” in the pursuit of looking after others. That’s all well and good and healthy.
However, in relationships, often it happens that partners polarize themselves and/or each other, with one shouldering all of the responsibility, and the other willfully losing their own agency.
The problem lies in that either role can be seductive—on the one hand, it’s nice to be admired and powerful and it’s a good feeling to look after one’s partner; on the other hand, it’s nice to have someone who will meet your every need. What love and trust!
Only, it becomes toxic when these roles stagnate, and each forgets how to step out of them. Each can become resentful of the other (for not pulling their weight, on one side, and for not being able to effortlessly solve all life problems unilaterally and provide endlessly in both time and substance, on the other), digging in to their own side and exacerbating the less healthy qualities.
As to the way out? It’s about self-exploration and mutual honesty—and mutual support:

Stickers and wristbands aren’t a reliable way to prevent mosquito bites. Here’s why
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.
Protecting yourself and family from mosquito bites can be challenging, especially in this hot and humid weather. Protests from young children and fears about topical insect repellents drive some to try alternatives such as wristbands, patches and stickers.
These products are sold online as well as in supermarkets, pharmacies and camping stores. They’re often marketed as providing “natural” protection from mosquitoes.
But unfortunately, they aren’t a reliable way to prevent mosquito bites. Here’s why – and what you can try instead.
Why is preventing mosquito bites important?
Mosquitoes can spread pathogens that make us sick. Japanese encephalitis and Murray Valley encephalitis viruses can have potentially fatal outcomes. While Ross River virus won’t kill you, it can cause potentially debilitating illnesses.
Health authorities recommend preventing mosquito bites by: avoiding areas and times of the day when mosquitoes are most active; covering up with long sleeved shirts, long pants, and covered shoes; and applying a topical insect repellent (a cream, lotion, or spray).
I don’t want to put sticky and smelly repellents on my skin!
While for many people, the “sting” of a biting mosquitoes is enough to prompt a dose of repellent, others are reluctant. Some are deterred by the unpleasant feel or smell of insect repellents. Others believe topical repellents contain chemicals that are dangerous to our health.
However, many studies have shown that, when used as recommended, these products are safe to use. All products marketed as mosquito repellents in Australia must be registered by the Australian Pesticides and Veterinary Medicines Authority; a process that provides recommendations for safe use.
How do topical repellents work?
While there remains some uncertainty about how the chemicals in topical insect repellents actually work, they appear to either block the sensory organs of mosquitoes that drive them to bite, or overpower the smells of our skin that helps mosquitoes find us.
Diethytolumide (DEET) is a widely recommended ingredient in topical repellents. Picaridin and oil of lemon eucalyptus are also used and have been shown to be effective and safe.
How do other products work?
“Physical” insect-repelling products, such as wristbands, coils and candles, often contain a botanically derived chemical and are often marketed as being an alternative to DEET.
However, studies have shown that devices such as candles containing citronella oil provide lower mosquito-bite prevention than topical repellents.
A laboratory study in 2011 found wristbands infused with peppermint oil failed to provide full protection from mosquito bites.
Even as topical repellent formulations applied to the skin, these botanically derived products have lower mosquito bite protection than recommended products such as those containing DEET, picaridin and oil of lemon eucalyptus.
Wristbands infused with DEET have shown mixed results but may provide some bite protection or bite reduction. DEET-based wristbands or patches are not currently available in Australia.
There is also a range of mosquito repellent coils, sticks, and other devices that release insecticides (for example, pyrethroids). These chemicals are primarily designed to kill or “knock down” mosquitoes rather than to simply keep them from biting us.
What about stickers and patches?
Although insect repellent patches and stickers have been available for many years, there has been a sudden surge in their marketing through social media. But there are very few scientific studies testing their efficacy.
Our current understanding of the way insect repellents work would suggest these small stickers and patches offer little protection from mosquito bites.
At best, they may reduce some bites in the way mosquito coils containing botanical products work. However, the passive release of chemicals from the patches and stickers is likely to be substantially lower than those from mosquito coils and other devices actively releasing chemicals.
One study in 2013 found a sticker infused with oil of lemon eucalyptus “did not provide significant protection to volunteers”.
Clothing impregnated with insecticides, such as permethrin, will assist in reducing mosquito bites but topical insect repellents are still recommended for exposed areas of skin.
Take care when using these products
The idea you can apply a sticker or patch to your clothing to protect you from mosquito bites may sound appealing, but these devices provide a false sense of security. There is no evidence they are an equally effective alternative to the topical repellents recommended by health authorities around the world. It only takes one bite from a mosquito to transmit the pathogens that result in serious disease.
It is also worth noting that there are some health warnings and recommendations for their use required by Australian Pesticides and Veterinary Medicines Authority. Some of these products warn against application to the skin (recommending application to clothing only) and to keep products “out of reach of children”. This is a challenge if attached to young children’s clothing.
Similar warnings are associated with most other topical and non-topical mosquito repellents. Always check the labels of these products for safe use recommendations.
Are there any other practical alternatives?
Topical insect repellents are safe and effective. Most can be used on children from 12 months of age and pose no health risks. Make sure you apply the repellent as a thin even coat on all exposed areas of skin.
But you don’t need “tropical strength” repellents for short periods of time outdoors; a range of formulations with lower concentrations of repellent will work well for shorter trips outdoors. There are some repellents that don’t smell as strong (for example, children’s formulations, odourless formulations) or formulations that may be more pleasant to use (for example, pump pack sprays).
Finally, you can always cover up. Loose-fitting long-sleeved shirts, long pants, and covered shoes will provide a physical barrier between you and mosquitoes on the hunt for your or your family’s blood this summer.

What Grief Does To Your Body (And How To Manage It)
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.
What Grief Does To The Body (And How To Manage It)
In life, we will almost all lose loved ones and suffer bereavement. For most people, this starts with grandparents, eventually moves to parents, and then people our own generation; partners, siblings, close friends. And of course, sometimes and perhaps most devastatingly, we can lose people younger than ourselves.
For something that almost everyone suffers, there is often very little in the way of preparation given beforehand, and afterwards, a condolences card is nice but can’t do a lot for our mental health.
And with mental health, our physical health can go too, if we very understandably neglect it at such a time.
So, how to survive devastating loss, and come out the other side, hopefully thriving? It seems like a tall order indeed.
First, the foundations:
You’re probably familiar with the stages of grief. In their most commonly-presented form, they are:
- Denial
- Anger
- Bargaining
- Depression
- Acceptance
You’ve probably also heard/read that we won’t always go through them in order, and also that grief is deeply personal and proceeds on its own timescale.
It is generally considered healthy to go through them.
What do they look like?
Naturally this can vary a lot from person to person, but examples in the case of bereavement could be:
- Denial: “This surely has not really happened; I’ll carry on as though it hasn’t”
- Anger: “Why didn’t I do xyz differently while I had the chance?!”
- Bargaining: “I will do such-and-such in their honor, and this will be a way of expressing the love I wish I could give them in a way they could receive”
- Depression: “What is the point of me without them? The sooner I join them, the better.”
- Acceptance: “I was so lucky that we had the time together that we did, and enriched each other’s lives while we could”
We can speedrun these or we can get stuck on one for years. We can bounce back and forth. We can think we’re at acceptance, and then a previous stage will hit us like a tonne of bricks.
What if we don’t?
Assuming that our lost loved one was indeed a loved one (as opposed to someone we are merely societally expected to mourn), then failing to process that grief will tend to have a big impact on our life—and health. These health problems can include:
As you can see, three out of five of those can result in death. The other two aren’t great either. So why isn’t this taken more seriously as a matter of health?
Death is, ironically, considered something we “just have to live with”.
But how?
Coping strategies
You’ll note that most of the stages of grief are not enjoyable per se. For this reason, it’s common to try to avoid them—hence denial usually being first.
But, that is like not getting a lump checked out because you don’t want a cancer diagnosis. The emotional reasoning is understandable, but it’s ultimately self-destructive.
First, have a plan. If a death is foreseen, you can even work out this plan together.
But even if that time has now passed, it’s “better late than never” to make a plan for looking after yourself, e.g:
- How you will try to get enough sleep (tricky, but sincerely try)
- How you will remember to eat (and ideally, healthily)
- How you will still get exercise (a walk in the park is fine; see some greenery and get some sunlight)
- How you will avoid self-destructive urges (from indirect, e.g. drinking, to direct, e.g. suicidality)
- How you will keep up with the other things important in your life (work, friends, family)
- How you will actively work to process your grief (e.g. journaling, or perhaps grief counselling)
Some previous articles of ours that may help:
- How To Keep On Keeping On ← this is about looking after general health when motivation is low
- The Mental Health First-Aid You’ll Hopefully Never Need ← this is about managing depression
- How To Stay Alive (When You Really Don’t Want To) ← this is about managing suicidality
- Life After Death? (Your Life; A Loved One’s Death) ← this is about bereavement and romance
If it works, it works
If we are all unique, then any relationship between any two people is uniqueness squared. Little wonder, then, that our grief may be unique too. And it can be complicated further:
- Sometimes we had a complicated relationship with someone
- Sometimes the circumstances of their death were complicated
There is, for that matter, such a thing as “complicated grief”:
Read more: Complicated grief and prolonged grief disorder (Medical News Today)
We also previously reviewed a book on “ambiguous loss”, exploring grieving when we cannot grieve in the normal way because someone is gone and/but/maybe not gone.
For example, if someone is in a long-term coma from which they may never recover, or if they are missing-presumed-dead. Those kinds of situations are complicated too.
Unusual circumstances may call for unusual coping strategies, so how can we discern what is healthy and what isn’t?
The litmus test is: is it enabling you to continue going about your life in a way that allows you to fulfil your internal personal aspirations and external social responsibilities? If so, it’s probably healthy.
Look after yourself. And if you can, tell your loved ones you love them today.

The Power of Hormones – by Dr. Max Nieuwdorp
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.
First a quick note on the author: he’s an MD & PhD, internist, endocrinologist, and professor. He knows his stuff.
There are a lot of books with “the new science of” in the title, and they don’t often pertain to science that is actually new, and in this case, for the most part the science contained within this book is quite well-established.
A strength of this book is that it’s not talking about hormones in just one specific aspect (e.g. menopause, pregnancy, etc) but rather, in the full span of human health, across the spectra of ages and sexes—and yes, also covering hormones that are not sex hormones, so for example also demystifying the different happiness-related neurotransmitters, as well as the hormones responsible for hunger and satiety, weight loss and gain, sleep and wakefulness, etc.
Which is all very good, because there’s a lot of overlap and several hormones fall into several categories there.
Moreover, the book covers how your personal cocktail of hormones impacts how you look, feel, behave, and more—there’s a lot about chronic health issues here too, and how to use the information in this book to if not outright cure, then at least ameliorate, many conditions.
Bottom line: this is an information-dense book with a lot of details great and small; if you read this, you’ll come away with a much better understanding of hormones than you had previously!
