❝What is Mediterranean diet which book to read?❞
We did a special edition about the Mediterranean Diet! So that’s a great starting point.
As to books, there are so many, and we review books about it from time to time, so keep an eye out for our daily “One-Minute Book Review” section. We do highly recommend “How Not To Die”, which is a science-heavy approach to diet-based longevity, and essentially describes the Mediterranean Diet, with some tweaks.

Unlimited Memory – by Kevin Horsley
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.
Premise: there are easily learnable techniques to rapidly (and greatly) improve one’s memory. We’ve touched on some of these methods before at 10almonds, but being a newsletter rather than a book, we’ve not been able to go as deeply into it as Horsley!
Your memory is far, far, far more powerful than you might realize, and this book will help unlock that. To illustrate…
Some of the book is given over to what are for most purposes “party tricks”, such as remembering pi to 10,000 places. Those things are fun, even if not as practical in today’s world of rarely needing to even know the actual digits of a phone number. However, they do also serve as a good example of just how much of “super memory” isn’t a matter of hard work, so much as being better organized about it.
Most of the book is focused on practical methods to improve the useful aspects of memory—including common mistakes!
If the book has any flaw it’s that the first chapter or so is spent persuading the reader of things we presumably already believe, given that we bought the book. For example, that remembering things is a learnable skill and that memory is functionally limitless. However, we still advise to not skip those chapters as they do contain some useful reframes as well.
Bottom line: if you read this book you will be astonished by how much you just learned—because you’ll be able to recall whole sections in detail! And then you can go apply that whatever areas of your life you wanted to when you bought the book.

What’s the difference between miscarriage and stillbirth?
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’s the difference? is a new editorial product that explains the similarities and differences between commonly confused health and medical terms, and why they matter.
Former US First Lady Michelle Obama revealed in her memoir she had a miscarriage. UK singer-songwriter and actor Lily Allen has gone on the record about her stillbirth.
Both miscarriage and stillbirth are sadly familiar terms for pregnancy loss. They can be traumatic life events for the prospective parents and family, and their impacts can be long-lasting. But the terms can be confused.
Here are some similarities and differences between miscarriage and stillbirth, and why they matter.
christinarosepix/Shutterstock Let’s start with some definitions
In broad terms, a miscarriage is when a pregnancy ends while the fetus is not yet viable (before it could survive outside the womb).
This is the loss of an “intra-uterine” pregnancy, when an embryo is implanted in the womb to then develop into a fetus. The term miscarriage excludes ectopic pregnancies, where the embryo is implanted outside the womb.
However, stillbirth refers to the end of a pregnancy when the fetus is normally viable. There may have been sufficient time into the pregnancy. Alternatively, the fetus may have grown large enough to be normally expected to survive, but it dies in the womb or during delivery.
The Australian Institute of Health and Welfare defines stillbirth as a fetal death of at least 20 completed weeks of gestation or with a birthweight of at least 400 grams.
Internationally, definitions of stillbirth vary depending on the jurisdiction.
How common are they?
It is difficult to know how common miscarriages are as they can happen when a woman doesn’t know she is pregnant. There may be no obvious symptoms or something that looks like a heavier-than-normal period. So miscarriages are likely to be more common than reported.
Studies from Europe and North America suggest a miscarriage occurs in about one in seven pregnancies (15%). More than one in eight women (13%) will have a miscarriage at some time in her life.
Around 1–2% of women have recurrent miscarriages. In Australia this is when someone has three or more miscarriages with no pregnancy in between.
Australia has one of the lowest rates of stillbirth in the world. The rate has been relatively steady over the past 20 years at 0.7% or around seven per 1,000 pregnancies.
Who’s at risk?
Someone who has already had a miscarriage or stillbirth has an increased risk of that outcome again in a subsequent pregnancy.
Compared with women who have had a live birth, those who have had a stillbirth have double the risk of another. For those who have had recurrent miscarriages, the risk of another miscarriage is four-fold higher.
Some factors have a u-shaped relationship, with the risk of miscarriage and stillbirth lowest in the middle.
For instance, maternal age is a risk factor for both miscarriage and stillbirth, especially if under 20 years old or older than 35. Increasing age of the male is only a risk factor for stillbirth, especially for fathers over 40.
An older dad can be a risk factor for stillbirth, but not miscarriage. Elizaveta Galitckaia/Shutterstock Similarly for maternal bodyweight, women with a body mass index or BMI in the normal range have the lowest risk of miscarriage and stillbirth compared with those in the obese or underweight categories.
Lifestyle factors such as smoking and heavy alcohol drinking while pregnant are also risk factors for both miscarriage and stillbirth.
So it’s important to not only avoid smoking and alcohol while pregnant, but before getting pregnant. This is because early in the pregnancy, women may not know they have conceived and could unwittingly expose the developing fetus.
Why do they happen?
Miscarriage often results from chromosomal problems in the developing fetus. However, genetic conditions or birth defects account for only 7-14% of stillbirths.
Instead, stillbirths often relate directly to pregnancy complications, such as a prolonged pregnancy or problems with the umbilical cord.
Maternal health at the time of pregnancy is another contributing factor in the risk of both miscarriage and stillbirths.
Chronic diseases, such as high blood pressure, diabetes, hypothyroidism (underactive thyroid), polycystic ovary syndrome, problems with the immune system (such as an autoimmune disorder), and some bacterial and viral infections are among factors that can increase the risk of miscarriage.
Similarly mothers with diabetes, high blood pressure, and untreated infections, such as malaria or syphilis, face an increased risk of stillbirth.
In many cases, however, the specific cause of pregnancy loss is not known.
How about the long-term health risks?
Miscarriage and stillbirth can be early indicators of health issues later in life.
For instance, women who have had recurrent miscarriages or recurrent stillbirths are at higher risk of cardiovascular disease (such as heart disease or stroke).
Our research has also looked at the increased risk of stroke. Compared with women who had never miscarried, we found women with a history of three or more miscarriages had a 35% higher risk of non-fatal stroke and 82% higher risk of fatal stroke.
Women who had a stillbirth had a 31% higher risk of a non-fatal stroke, and those who had had two or more stillbirths were at a 26% higher risk of a fatal stroke.
We saw similar patterns in chronic obstructive pulmonary disease or COPD, a progressive lung disease with respiratory symptoms such as breathlessness and coughing.
Our data showed women with a history of recurrent miscarriages or stillbirths were at a 36% or 67% higher risk of COPD, respectively, even after accounting for a history of asthma.
Long-term health risks of recurrent miscarriages or stillbirths include developing lung disease later in life. PRPicturesProduction/Shutterstock Why is all this important?
Being well-informed about the similarities and differences between these two traumatic life events may help explain what has happened to you or a loved one.
Where risk factors can be modified, such as smoking and obesity, this information can be empowering for individuals who wish to reduce their risk of miscarriage and stillbirth and make lifestyle changes before they become pregnant.
More information and support about miscarriage and stillbirth is available from SANDS and Pink Elephants.

Black Coffee vs Orange Juice – 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 black coffee to orange juice, we picked the coffee.
Why?
While this one isn’t a very like-for-like choice, it’s a choice often made, so it bears examining.
In favor of the orange juice, it has vitamins A and C and the mineral potassium, while the coffee contains no vitamins or minerals beyond trace amounts.
However, to offset that: drinking juice is one of the worst ways to consume sugar; the fruit has not only been stripped of its fiber, but also is in its most readily absorbable state (liquid), meaning that this is going to cause a blood sugar spike, which if done often can lead to insulin resistance, type 2 diabetes, non-alcoholic fatty liver disease, and more. Now, the occasional glass of orange juice (and resultant blood sugar spike) isn’t going to cause disease by itself, but everything we consume tips the scales of our health towards wellness or illness (or sometimes both, in different ways), and in this case, juice has a rather major downside that ought not be ignored.
In favor of the coffee, it has a lot of beneficial phytochemicals (mostly antioxidant polyphenols of various kinds), with no drawbacks worth mentioning unless you have a pre-existing condition of some kind.
Coffee can of course be caffeinated or decaffeinated, and we didn’t specify which here. Caffeine has some pros and cons that at worst, balance each other out, and whether or not it’s caffeinated, there’s nothing in coffee to offset the beneficial qualities of the antioxidants we mentioned before.
Obviously, in either case we are assuming consuming in moderation.
In short:
- orange juice has negatives that at least equal, if not outweigh, its positives
- coffee‘s benefits outweigh any drawbacks for most people

Frozen/Thawed/Refrozen Meat: How Much Is Safety, And How Much Is Taste?
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 You Can (And Can’t) Safely Do With Frozen Meat
Yesterday, we asked you:
❝You have meat in the freezer. How long is it really safe to keep it?❞
…and got a range of answers, mostly indicating to a) follow the instructions (a very safe general policy) and b) do not refreeze if thawed because that would be unsafe. Fewer respondents indicated that meat could be kept for much longer than guidelines say, or conversely, that it should only be kept for weeks or less.
So, what does the science say?
Meat can be kept indefinitely (for all intents and purposes) in a freezer; it just might get tougher: True or False?
False, assuming we are talking about a normal household electrical freezer that bottoms out at about -18℃ / 0℉.
Fun fact: cryobiologists cryopreserve tissue samples (so basically, meat) at -196℃ / -320℉, and down at those temperatures, the tissues will last a lot longer than you will (and, for all practical purposes: indefinitely). There are other complications with doing so (such as getting the sample through the glass transition point without cracking it during the vitrification process) but those are beyond the scope of this article.
If you remember back to your physics or perhaps chemistry classes at school, you’ll know that molecules move more quickly at higher temperatures, and more slowly at lower ones, only approaching true stillness as they near absolute zero (-273℃ / -459℉ / 0K ← we’re not saying it’s ok, although it is; rather, that is zero kelvin; no degree sign is used with kelvins)
That means that when food is frozen, the internal processes aren’t truly paused; it’s just slowed to a point of near imperceptibility.
So, all the way up at the relatively warm temperatures of a household freezer, a lot of processes are still going on.
What this means in practical terms: those guidelines saying “keep in the freezer for up to 4 months”, “keep in the freezer for up to 9 months”, “keep in the freezer for up to 12 months” etc are being honest with you.
More or less, anyway! They’ll usually underestimate a little to be on the safe side—but so should you.
Bad things start happening within weeks at most: True or False?
False, for all practical purposes. Again, assuming a normal and properly-working household freezer as described above.
(True, technically but misleadingly: the bad things never stopped; they just slowed down to a near imperceptible pace—again, as described above)
By “bad” here we should clarify we mean “dangerous”. One subscriber wrote:
❝Meat starts losing color and flavor after being in the freezer for too long. I keep meat in the freezer for about 2 months at the most❞
…and as a matter of taste, that’s fair enough!
It is unsafe to refreeze meat that has been thawed: True or False?
False! Assuming it has otherwise been kept chilled, just the same as for fresh meat.
Food poisoning comes from bacteria, and there is nothing about the meat previously having been frozen that will make it now have more bacteria.
That means, for example…
- if it was thawed (but chilled) for a period of time, treat it like you would any other meat that has been chilled for that period of time (so probably: use it or freeze it, unless it’s been more than a few days)
- if it was thawed (and at room temperature) for a period of time, treat it like you would any other meat that has been at room temperature for that period of time (so probably: throw it out, unless the period of time is very small indeed)
The USDA gives for 2 hours max at room temperature before considering it unsalvageable, by the way.
However! Whenever you freeze meat (or almost anything with cells, really), ice crystals will form in and between cells. How much ice crystallization occurs depends on several variables, with how much water there is present in the food is usually the biggest factor (remember that animal cells are—just like us—mostly water).
Those ice crystals will damage the cell walls, causing the food to lose structural integrity. When you thaw it out, the ice crystals will disappear but the damage will be left behind (this is what “freezer burn” is).
So if your food seems a little “squishy” after having been frozen and thawed, that’s why. It’s not rotten; it’s just been stabbed countless times on a microscopic level.
The more times you freeze and thaw and refreeze food, the more this will happen. Your food will degrade in structural integrity each time, but the safety of it won’t have changed meaningfully.

GABA Against Stress/Anxiety
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.
A Neurotransmitter Less Talked-About
GABA is taken by many people as a supplement, mostly as a mood modifier, though its health claims go beyond the recreational—and also, we’re of the opinion that mental health is also just health, and if it works, it works. We’ll explore some of the claims and science behind them today…
What is GABA?
GABA stands for gamma-aminobutyric acid, and it’s a neurotransmitter. It’s a lot less talked-about than for example dopamine or serotonin, but it’s very important nonetheless.
We make it ourselves inside our body, and we can also get it from our food, or supplement it, and some drugs will also have an effect on its presence and/or activity in our body.
What foods is it found in?
- Animals, obviously (just like in human brains*)
- Fermented foods (many kinds)
- Yeast
- Tea
- Tomatoes
- Mulberries
For more details, see:
γ-Aminobutyric acid found in fermented foods and beverages: current trends
*However, we do not recommend eating human brains, due to the risk of CJD and prion diseases in general.
What claims are made about it and are they true?
For brevity, we’ll give a little spoiler up-front: all the popular claims for it appear to be valid, though there’s definitely room for a lot more human trials (we skipped over a lot of rodent studies today!).
So we’ll just drop some of its main benefits, and human studies to back those.
Reduction of stress and anxiety
GABA decreases task-related stress and anxiety within 30 minutes of being taken, both in subjective measures (i.e., self-reports) and in objective clinical physiological measures:
Cognitive enhancement
It’s not a does-everything nootropic like some, but it does have clear benefits to episodic memory:
❝GABA intake might help to distribute limited attentional resources more efficiently, and can specifically improve the identification and ordering of visual events that occur in close temporal succession❞
One of the things that makes this one important is that it also deals with the often-asked question of “does GABA pass the blood-brain barrier”:
❝The present findings do give further credence to the idea that oral ingestion does allow GABA to reach the brain and exert direct effects on cognition, which in the present case were specific to temporal attention.❞
Read more:
Supplementation of gamma-aminobutyric acid (GABA) affects temporal, but not spatial visual attention
Potential for more
We take care to give good quality sources, so the following study comes with a big caveat that it has since been retracted. Why was it retracted, you wonder?
It’s about the sample; they cite “30 healthy adults”, but neglected tp mention that this figure was initially 46. What happened to the other 16 participants is unclear, but given that this was challenged and the challenge not answered, it was sufficient for the journal (Nature) to pull the study, in case of deliberate sample bias.
However! Running the numbers in their results section, a probability of 0.03 is very compelling unless the disappearance of 16 subjects was outright fraudulent (which we regrettably cannot know either way).
Here’s the study (so take it with a pinch of salt, considering the above), and taken at face value, it shows how GABA supplementation improves accurate reactions to fast-moving visual and auditory stimuli:
RETRACTED ARTICLE: γ-Aminobutyric acid (GABA) administration improves action selection processes: a randomised controlled trial
…so, hopefully this experiment will be repeated, without disappearing participants!
The sweet spot
You may be wondering how something that slows a person down (having a relaxing effect) can also speed a person up. This has to do with what it is and isn’t affecting; think of it like a “focus mode” on your computer or other device that greys-out everything else a bit so that you can focus on what you’re doing.
It’s in some ways (by different neurochemical pathways, though) a similar effect to the “relaxed alertness” created by l-theanine supplementation.
There’s also a sweet spot whereby GABA is toning some things down just the right amount, without adversely affecting performance in areas we don’t want slowed down. For the science of this, see:
Is it safe?
GABA is “Generally Recognized As Safe”. However:
- you should speak with your pharmacist if you are taking any medications for blood pressure or epilepsy, as GABA supplementation may cause them to work too well.
- you should absolutely not take GABA with alcohol or opioids as (dose-dependent for all the substances involved, and also depending on your metabolic base rate and other factors) its acute depression of the CNS can mean you relax and slow down too much, and you may find yourself not breathing often enough to sustain life.
Aside from that, it is considered safe up to at least 1g/kg/day*. Given that popular doses are 120–750mg, and most people weigh more than 750g, this is very safe for most people:

Laziness Does Not Exist – by Dr. Devon Price
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.
Some cultures prize productivity as an ideal above most other things, and it’s certainly so in the US. Not only is this not great for mental health in general, but also—as Dr. Price explains—it’s based on a lie.
Generally speaking, when a person appears lazy there is something stopping them/you from doing better, and it’s not some mystical unseen force of laziness, not a set character trait, not a moral failing. Rather, the root cause may be physical, psychological, socioeconomic, or something else entirely.
Those causes can in some cases be overcome (for example, a little CBT can often set aside perfectionist anxiety that results in procrastination), and in some cases they can’t, at least on an individual level (disabilities often stubbornly remain disabling, and societal problems require societal solutions).
This matters for our mental health in areas well beyond the labor marketplace, of course, and these ideas extend to personal projects and even personal relationships. Whatever it is, if it’s leaving you exhausted, then probably something needs to be changed (even if the something is just “expectations”).
The book does offer practical solutions to all manner of such situations, improving what can be improved, making easier what can be made easier, and accepting what just needs to be accepted.
The style of this book is casual yet insightful and deep, easy-reading yet with all the acumen of an accomplished social psychologist.
Bottom line: if life leaves you exhausted, this book can be the antidote and cure
