Most of us try to live rational lives. We try to make the best decisions we can based on the information we have… And if we’re thoughtful, we even try to be aware of common logical fallacies, and overcome our personal biases too. But is self-delusion ever useful?
Dr. Stuart Vyse, psychologist and Fellow for the Committee for Skeptical Inquiry, argues that it can be.
From self-fulfilling prophecies of optimism and pessimism, to the role of delusion in love and loss, Dr. Vyse explores what separates useful delusion from dangerous irrationality.
We also read about such questions as (and proposed answers to):
- Why is placebo effect stronger if we attach a ritual to it?
- Why are negative superstitions harder to shake than positive ones?
- Why do we tend to hold to the notion of free will, despite so much evidence for determinism?
The style of the book is conversational, and captivating from the start; a highly compelling read.
Bottom line: if you’ve ever felt yourself wondering if you are deluding yourself and if so, whether that’s useful or counterproductive, this is the book for you!

Watermelon vs Grapes – 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 watermelon to grapes, we picked the watermelon.
Why?
It was close! And certainly both are very healthy.
Both fruits are (like most fruits) good sources of water, fiber, vitamins, and minerals. Any sugar content (of which grapes are slightly higher) is offset by their fiber content and polyphenols.
See: Which Sugars Are Healthier, And Which Are Just The Same?
While both are good sources of vitamins A and C, watermelon has about 10x as much vitamin A, and about 6x as much vitamin C (give or take individual plants, how they were grown, etc, but the overall balance is clearly in watermelon’s favor).
When it comes to antioxidants, both fruits are good, but again watermelon is the more potent source. Grapes famously contain resveratrol, and they also contain quercetin, albeit you’d have to eat quite a lot of grapes to get a large portion.
Now, having to eat a lot of grapes might not sound like a terrible fate (who else finds that the grapes are gone by the time the groceries are put away?), but we are comparing the fruits here, and on a list of “100 best foods for quercetin”, for example, grapes took 99th place.
Watermelon’s main antioxidant meanwhile is lycopene, and watermelon is one of the best sources of lycopene in existence (better even than tomatoes).
We’ll have to do a main feature about lycopene sometime soon, so watch this space
Take care!

Rose Hips vs Blueberries – 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 rose hips to blueberries, we picked the rose hips.
Why?
Both of these fruits are abundant sources of antioxidants and other polyphenols, but one of them stands out for overall nutritional density:
In terms of macros, rose hips have about 2x the carbohydrates, and/but about 10x the fiber. That’s an easy calculation and a clear win for rose hips.
When it comes to vitamins, rose hips have a lot more of vitamins A, B2, B3, B5, B6, C, E, K, and choline. On the other hand, blueberries boast more of vitamins B1 and B9. That’s a 9:2 lead for rose hips, even before we consider rose hips’ much greater margins of difference (kicking off with 80x the vitamin A, for instance, and many multiples of many of the others).
In the category of minerals, rose hips have a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and zinc. Meanwhile, blueberries are not higher in any minerals.
In short: as ever, enjoy both, but if you’re looking for nutritional density, there’s a clear winner here and it’s rose hips.

Study links microplastics with human health problems – but there’s still a lot we don’t know
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.
Mark Patrick Taylor, Macquarie University and Scott P. Wilson, Macquarie University
A recent study published in the prestigious New England Journal of Medicine has linked microplastics with risk to human health.
The study involved patients in Italy who had a condition called carotid artery plaque, where plaque builds up in arteries, potentially blocking blood flow. The researchers analysed plaque specimens from these patients.
They found those with carotid artery plaque who had microplastics and nanoplastics in their plaque had a higher risk of heart attack, stroke, or death (compared with carotid artery plaque patients who didn’t have any micro- or nanoplastics detected in their plaque specimens).
Importantly, the researchers didn’t find the micro- and nanoplastics caused the higher risk, only that it was correlated with it.
So, what are we to make of the new findings? And how does it fit with the broader evidence about microplastics in our environment and our bodies?
What are microplastics?
Microplastics are plastic particles less than five millimetres across. Nanoplastics are less than one micron in size (1,000 microns is equal to one millimetre). The precise size classifications are still a matter of debate.
Microplastics and nanoplastics are created when everyday products – including clothes, food and beverage packaging, home furnishings, plastic bags, toys and toiletries – degrade. Many personal care products contain microsplastics in the form of microbeads.
Plastic is also used widely in agriculture, and can degrade over time into microplastics and nanoplastics.
These particles are made up of common polymers such as polyethylene, polypropylene, polystyrene and polyvinyl chloride. The constituent chemical of polyvinyl chloride, vinyl chloride, is considered carcinogenic by the US Environmental Protection Agency.
Of course, the actual risk of harm depends on your level of exposure. As toxicologists are fond of saying, it’s the dose that makes the poison, so we need to be careful to not over-interpret emerging research.
A closer look at the study
This new study in the New England Journal of Medicine was a small cohort, initially comprising 304 patients. But only 257 completed the follow-up part of the study 34 months later.
The study had a number of limitations. The first is the findings related only to asymptomatic patients undergoing carotid endarterectomy (a procedure to remove carotid artery plaque). This means the findings might not be applicable to the wider population.
The authors also point out that while exposure to microplastics and nanoplastics has been likely increasing in recent decades, heart disease rates have been falling.
That said, the fact so many people in the study had detectable levels of microplastics in their body is notable. The researchers found detectable levels of polyethylene and polyvinyl chloride (two types of plastic) in excised carotid plaque from 58% and 12% of patients, respectively.
These patients were more likely to be younger men with diabetes or heart disease and a history of smoking. There was no substantive difference in where the patients lived.
Inflammation markers in plaque samples were more elevated in patients with detectable levels of microplastics and nanoplastics versus those without.
Microplastics are created when everyday products degrade. JS14/Shutterstock And, then there’s the headline finding: patients with microplastics and nanoplastics in their plaque had a higher risk of having what doctors call “a primary end point event” (non-fatal heart attack, non-fatal stroke, or death from any cause) than those who did not present with microplastics and nanoplastics in their plaque.
The authors of the study note their results “do not prove causality”.
However, it would be remiss not to be cautious. The history of environmental health is replete with examples of what were initially considered suspect chemicals that avoided proper regulation because of what the US National Research Council refers to as the “untested-chemical assumption”. This assumption arises where there is an absence of research demonstrating adverse effects, which obviates the requirement for regulatory action.
In general, more research is required to find out whether or not microplastics cause harm to human health. Until this evidence exists, we should adopt the precautionary principle; absence of evidence should not be taken as evidence of absence.
Global and local action
Exposure to microplastics in our home, work and outdoor environments is inevitable. Governments across the globe have started to acknowledge we must intervene.
The Global Plastics Treaty will be enacted by 175 nations from 2025. The treaty is designed, among other things, to limit microplastic exposure globally. Burdens are greatest especially in children and especially those in low-middle income nations.
In Australia, legislation ending single use plastics will help. So too will the increased rollout of container deposit schemes that include plastic bottles.
Microplastics pollution is an area that requires a collaborative approach between researchers, civil societies, industry and government. We believe the formation of a “microplastics national council” would help formulate and co-ordinate strategies to tackle this issue.
Little things matter. Small actions by individuals can also translate to significant overall environmental and human health benefits.
Choosing natural materials, fabrics, and utensils not made of plastic and disposing of waste thoughtfully and appropriately – including recycling wherever possible – is helpful.

Unlock Your Menopause Type – by Dr. Heather Hirsch
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 featured Dr. Hirsch before, here, and mentioned this book which, at the time, we had not yet reviewed. So, here it is:
What sets this apart from a lot of menopause books is that there’s a lot less “eat these foods and your body will magically stop exhibiting symptoms of menopause” and a lot more clinical observations and then evidence-based recommendations.
Which is not to say don’t eat broccoli and almonds; by all means, they’re great foods and contain valuable nutrients that will help. But it is to say that if your doctor’s prescription is just broccoli and almonds, maybe have those as a snack while you’re looking for a second opinion.
Dr. Hirsch goes through various “menopause types”, but it’s not so much “astrology for gynecologists” and more “here are clusters of menopause symptoms set against timeline of presentation, and they can be categorized into six main ways that between them, cover pretty much all my patients, which have been many”.
So if you, dear reader, are menopausal (including peri- or post-), then the chances are very good that you will see yourself in one of those six sets.
She then goes about how to prioritize relief and safety, and personalize a treatment plan, and maintain the best menopausal care for you, going forward.
The style is easy-reading pop-science, punctuated by clinical science and 35 pages of references. She’s also, unlike a lot of authors in the genre, manifestly not invested in being a celebrity or making a personality cult out of her recommendations; she’s happy to stick to the science and put out good advice.
Bottom line: if you or someone you love is menopausal (including peri- or post-), this is a top-tier book.

The Polyvagal Theory – by Dr. Stephen Porges
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 ever find that your feelings (or occasionally: lack thereof) sometimes can seem mismatched with the observed facts of your situation? This book unravels that mystery—or rather, that stack of mysteries.
Dr. Porges’ work on this topic is, by the way, the culmination of 40 years of research. While he’s not exactly a household name to the layperson, he’s very respected in his field, and this book is his magnum opus.
Here he explains the disparate roles of the two branches of the vagus nerve (hence: polyvagal theory). At least, the two branches that we mammals have; non-mammalian vertebrates have only one. This makes a big difference, because of the cascade of inhibitions that this allows.
The answer to the very general question “What stops you from…?” is usually found somewhere down this line of cascade of inhibitions.
These range from “what stops you from quitting your job/relationship/etc” to “what stops you from freaking out” to “what stops you from relaxing” to “what stops you from reacting quickly” to “what stop you from giving up” to “what stops you from gnawing your arm off” and many many more.
And because sometimes we wish we could do something that we can’t, or wish we wouldn’t do something that we do, understanding this process can be something of a cheat code to life.
A quick note on style: the book is quite dense and can be quite technical, but should be comprehensible to any layperson who is content to take their time, because everything is explained as we go along.
Bottom line: if you’d like to better understand the mysteries of how you feel vs how you actually are, and what that means for what you can or cannot wilfully do, this is a top-tier book

Counterclockwise – by Dr. Ellen Langer
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 previously about Dr. Langer’s famous “Counterclockwise” study that saw reversals in biological markers of aging after a one-week intervention that consisted only of a (albeit rather intensive) mental reframe with regard to their age.
This book, as you might expect from the title, refers to that experiment a lot—but it doesn’t stop there. While the Counterclockwise experiment remains Dr. Langer’s most well-known, it’s not her most recent, and she draws from a wealth of research (her own and that of her colleagues in the field) to show the extent and limit of psychosomatic effect on aging.
Note:
- psychosomatic effect does not mean: “imagining it”
- psychosomatic effect means: “your brain regulates almost everything else in your body, directly or indirectly, including your autonomic functions, which includes immune function, tissue replacement, and more”
And as for when it comes to aging? Aging, like cancer, is in large part a problem of immune dysfunction; in both cases cells (be they senescent or cancerous, respectively) are not being killed when they are supposed to be, and in both cases, better instructions will improve the matter.
Many larger-scale markers of aging, such as mobility, are a case of the body only being able to do what the tissues allow, and the tissues are being constantly rebuilt (for better or for worse) according to autonomically-implemented specifications, and cells’ ability to carry out those orders.
Beyond the cellular physiology, this book discusses (a lot) the brain-down mechanisms by which the most powerful organ in our body can tell the rest of the body how old to be.
Dr. Langer also discusses the matter of “priming”, that is to say, how external factors prime us to believe certain things about our age and, with it, our health. These things can include popular media, conversations with friends and family, and healthcare providers’ framing of certain issues.
For example, a person just under a certain age and a person just over a certain age could both go to the doctor with the same complaint—a pain in a certain joint, let’s say. The doctor may refer the slightly younger patient for an x-ray because “let’s see what’s going on here”, and prescribe the slightly older patient some painkillers because “this is perfectly normal at your age”. One resultant problem is obvious: a difference in the standard of care. But the other resultant problem is less obvious: the older patient has now been primed to believe, by a confident authority figure, “it is natural for my body to be in a state of decline now, and this is what to expect”.
Thus, Dr. Langer prescribes mindfulness, not in the mindfulness meditation sense (though sure, do that too), but rather in the sense of consciously interacting with the world and making our own decisions about our own health and, yes, our own age. Because after all, our body neither knows nor cares how many times it has flown around the sun, and merely responds to physiological stimuli—including those we can influence with psychological reframing.
The book is not, per se, a “how-to” guide, rather it is an explanatory treatise, but it contains more than enough information to put it into practice, and indeed, she does also provide some exercises to do along the way.
The style is… Vivacious, without being especially upbeat. Dr. Langer is enthused about her work, yes, but she’s also angry at how many people are having their health sabotaged on the daily, and calls for a more health-first approach (as opposed to illness-first).
Bottom line: this is the book on our brain’s power over aging, so if that topic interests you, this book absolutely belongs on your bookshelf. Well, in your hands, and then on the bookshelf, and then back in your hands from time to time.
