Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Articles are very informative and helpful. Maybe it’s me but things seem to lean more toward females. That being said don’t forget us males❞
Rest assured, we could never forget you! We try to make as much as possible of our content applicable to as many as possible of our readers, but of course not everything can be relevant for everyone.
This is, presumably, in response to our recent feature on menopausal health, because previous to that, our next-most-recent main feature that centred women’s health was a month ago—that was about breast cancer, and did have a section on breast cancer in men too. You might also enjoy the book we reviewed recently about prostate health, or our regular sponsor offering testosterone therapy. Please feel free to check out our articles on saw palmetto against male pattern baldness and BPH, as well as mental health issues that disproportionally affect men.
And of course, if you have specific questions/requests about men’s health (or any other health topic) we’re only ever an email away (or use the handy feedback widget, as you did to make this request)!

The Mediterranean Diet: What Is It Good For?
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.
More to the point: what isn’t it good for?
- It’s been found to reduce all-cause mortality, which is about the best thing one can say of any diet.
- It’s especially good for heart health and against cancer.
- It’s particularly recommended for the prevention or management of diabetes.
- It’s also been found, societally, to reduce general healthcare costs—basically, people get sick less and so have fewer healthcare costs.
What brought it to the attention of the world’s scientific community?
Back in the 1950s, physiologist Ancel Keys wondered why poor people in Italian villages were healthier than wealthy New Yorkers. Upon undertaking studies, he narrowed it down to the Mediterranean diet—something he’d then take on as a public health cause for the rest of his career.
Keys himself lived to the ripe old age of 100, by the way.
When we say “Mediterranean Diet”, what image comes to mind?
We’re willing to bet that tomatoes feature (great source of lycopene, by the way), but what else?
- Salads, perhaps? Vegetables, olives? Olive oil, yea or nay?
- Bread? Pasta? Prosciutto, salami? Cheese?
- Pizza but only if it’s Romana style, not Chicago?
- Pan-seared liver, with some fava beans and a nice Chianti?
In reality, the diet is based on what was historically eaten specifically by Italian peasants. If the word “peasants” conjures an image of medieval paupers in smocks and cowls, and that’s not necessarily wrong, further back historically… but the relevant part here is that they were people who lived and worked in the countryside.
They didn’t have money for meat, which was expensive, nor the industrial setting for refined grain products to be affordable. They didn’t have big monocrops either, which meant no canola oil, for example… Olives produce much more easily extractable oil per plant, so olive oil was easier to get. Nor, of course, did they have the money (or infrastructure) for much in the way of imports.
So what foods are part of “the” Mediterranean Diet?
- Fruits. These would be fruits grown locally, but no need to sweat that, dietwise. It’s hard to go wrong with fruit.
- Tomatoes yes. So many tomatoes. (Knowledge is knowing tomato is a fruit. Wisdom is not putting it in a fruit salad)
- Non-starchy vegetables (e.g. eggplant yes, potatoes no)
- Greens (spinach, kale, lettuce, all those sorts of things)
- Beans and other legumes (whatever was grown nearby)
- Whole grain products in moderation (wholegrain bread, wholewheat pasta)
- Olives and olive oil. Special category, single largest source of fat in the Mediterranean diet, but don’t overdo it.
- Dairy products in moderation (usually hard cheeses, as these keep well)
- Fish, in moderation. Typically grilled, baked, steamed even. Not fried.
- Other meats as a rarer luxury in considerable moderation. There’s more than one reason prosciutto is so thinly sliced!

Protein: How Much Do We Need, Really?
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.
Mythbusting Protein!
Yesterday, we asked you for your policy on protein consumption. The distribution of responses was as follows:
- A marginal majority (about 55%) voted for “Protein is very important, but we can eat too much of it”
- A large minority (about 35%) voted for “We need lots of protein; the more, the better!”
- A handful (about 4%) voted for “We should go as light on protein as possible”
- A handful (6%) voted for “If we don’t eat protein, our body will create it from other foods”
So, what does the science say?
If we don’t eat protein, our body will create it from other foods: True or False?
Contingently True on an absurd technicality, but for all practical purposes False.
Our body requires 20 amino acids (the building blocks of protein), 9 of which it can’t synthesize and absolutely must get from food. Normally, we get those amino acids from protein in our diet, and we can also supplement them by buying amino acid supplements.
Specifically, we require (per kg of bodyweight) a daily average of:
- Histidine: 10 mg
- Isoleucine: 20 mg
- Leucine: 39 mg
- Lysine: 30 mg
- Methionine: 10.4 mg
- Phenylalanine*: 25 mg
- Threonine: 15 mg
- Tryptophan: 4 mg
- Valine: 26 mg
*combined with the non-essential amino acid tyrosine
Source: Protein and Amino Acid Requirements In Human Nutrition: WHO Technical Report
However, to get the requisite amino acid amounts, without consuming actual protein, would require gargantuan amounts of supplementation (bearing in mind bioavailability will never be 100%, so you’ll always need to take more than it seems), using supplements that will have been made by breaking down proteins anyway.
So unless you live in a laboratory and have access to endless amounts of all of the required amino acids (you can’t miss even one; you will die), and are willing to do that for the sake of proving a point, then you do really need to eat protein.
Your body cannot, for example, simply break down sugar and use it to make the protein you need.
On another technical note… Do bear in mind that many foods that we don’t necessarily think of as being sources of protein, are sources of protein.
Grains and grain products, for example, all contain protein; we just don’t think of them as that because their macronutritional profile is heavily weighted towards carbohydrates.
For that matter, even celery contains protein. How much, you may ask? Almost none! But if something has DNA, it has protein. Which means all plants and animals (at least in their unrefined forms).
So again, to even try to live without protein would very much require living in a laboratory.
We can eat too much protein: True or False?
True. First on an easy technicality; anything in excess is toxic. Even water, or oxygen. But also, in practical terms, there is such a thing as too much protein. The bar is quite high, though:
❝Based on short-term nitrogen balance studies, the Recommended Dietary Allowance of protein for a healthy adult with minimal physical activity is currently 0.8 g protein per kg bodyweight per day❞
❝To meet the functional needs such as promoting skeletal-muscle protein accretion and physical strength, dietary intake of 1.0, 1.3, and 1.6 g protein per kg bodyweight per day is recommended for individuals with minimal, moderate, and intense physical activity, respectively❞
❝Long-term consumption of protein at 2 g per kg bodyweight per day is safe for healthy adults, and the tolerable upper limit is 3.5 g per kg bodyweight per day for well-adapted subjects❞
❝Chronic high protein intake (>2 g per kg bodyweight per day for adults) may result in digestive, renal, and vascular abnormalities and should be avoided❞
Source: Dietary protein intake and human health
To put this into perspective, if you weigh about 160lbs (about 72kg), this would mean eating more than 144g protein per day, which grabbing a calculator means about 560g of lean beef, or 20oz, or 1¼lb.
If you’re eating quarter-pounder burgers though, that’s not usually so lean, so you’d need to eat more than nine quarter-pounder burgers per day to get too much protein.
High protein intake damages the kidneys: True or False?
True if you have kidney damage already; False if you are healthy. See for example:
- Effects of dietary protein restriction on the progression of advanced renal disease in the modification of diet in renal disease study
- A high protein diet has no harmful effects: a one-year crossover study in healthy male athletes
High protein intake increases cancer risk: True or False?
True or False depending on the source of the protein, so functionally false:
- Eating protein from red meat sources has been associated with higher risk for many cancers
- Eating protein from other sources has been associated with lower risk for many cancers
Source: Red Meat Consumption and Mortality Results From 2 Prospective Cohort Studies
High protein intake increase risk of heart disease: True or False?
True or False depending on the source of the protein, so, functionally false:
- Eating protein from red meat sources has been associated with higher risk of heart disease
- Eating protein from other sources has been associated with lower risk of heart disease
Source: Major Dietary Protein Sources and Risk of Coronary Heart Disease in Women
In summary…
Getting a good amount of good quality protein is important to health.
One can get too much, but one would have to go to extremes to do so.
The source of protein matters:
- Red meat is associated with many health risks, but that’s not necessarily the protein’s fault.
- Getting plenty of protein from (ideally: unprocessed) sources such as poultry, fish, and/or plants, is critical to good health.
- Consuming “whole proteins” (that contain all 9 amino acids that we can’t synthesize) are best.

The Intelligence Trap – by David Robson
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’re including this one under the umbrella of “general wellness”, because it happens that a lot of very intelligent people make stunningly unfortunate choices sometimes, for reasons that may baffle others.
The author outlines for us the various reasons that this happens, and how. From the famous trope of “specialized intelligence in one area”, to the tendency of people who are better at acquiring knowledge and understanding to also be better at acquiring biases along the way, to the hubris of “I am intelligent and therefore right as a matter of principle” thinking, and many other reasons.
Perhaps the greatest value of the book is the focus on how we can avoid these traps, narrow our bias blind spots, and play to our strengths while paying full attention to our weaknesses.
The style is very readable, despite having a lot of complex ideas discussed along the way. This is entirely to be expected of this author, an award-winning science writer.
Bottom line: if you’d like to better understand the array of traps that disproportionately catch out the most intelligent people (and how to spot such), then this is a great book for you.

Grapefruit vs Orange – 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 grapefruit to orange, we picked the orange.
Why?
It’s easy, when guessing which is the healthier out of two things, to guess that the more expensive or perhaps less universally available one is the healthier. But it’s not always so, and today is one of those cases!
In terms of macros, they are very similar fruits, with almost identical levels of carbohydrates, proteins, and fats, as well as water. Looking more carefully, we find that grapefruit’s sugars contain a slightly high proportion of fructose; not enough to make it unhealthy by any means (indeed, no whole unprocessed fruit is unhealthy unless it’s literally poisonous), but it is a thing to note if we’re micro-analysing the macronutrients. Also, oranges have slightly more fiber, which is always a plus.
When it comes to vitamins, oranges stand out with more of vitamins B1, B2, B3, B6, B9, C, and E, while grapefruit boasts more vitamin A (hence its color). Still, we’re calling this category another win for oranges.
In the category of minerals, oranges again sweep with more calcium, copper, iron, magnesium, manganese, potassium, and selenium, while grapefruit has just a little more phosphorus. So, another easy win for oranges.
One final consideration that’s not shown in the nutritional values, is that grapefruit contains furanocoumarin, which can inhibit cytochrome P-450 3A4 isoenzyme and P-glycoptrotein transporters in the intestine and liver—slowing down their drug metabolism capabilities, thus effectively increasing the bioavailability of many drugs manifold. It can also be found in lower quantities in Seville (sour) oranges, and it’s not present (or at least, if it is, it’s in truly tiny quantities) in most oranges.
This may sound superficially like a good thing (improving bioavailability of things we want), but in practice it means that in the case of many drugs, if you take them with (or near in time to) grapefruit or grapefruit juice, then congratulations, you just took an overdose. This happens with a lot of meds for blood pressure, cholesterol (including statins), calcium channel-blockers, anti-depressants, benzo-family drugs, beta-blockers, and more. Oh, and Viagra, too. Which latter might sound funny, but remember, Viagra’s mechanism of action is blood pressure modulation, and that is not something you want to mess around with unduly. So, do check with your pharmacist to know if you’re on any meds that would be affected by grapefruit or grapefruit juice!
All in all, today’s sections add up to an overwhelming win for oranges!

This Week In Brain News
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.
While reading this week’s health news, we’ve singled out three brain-related articles to feature here:
Bad breath now, bad brain later?
Researchers found links between oral microbiome populations, and changes in brain function with aging. The short version is indeed “bad breath now = bad brain later”, but more specifically:
- People who had large numbers of the bacteria groups Neisseria and Haemophilus had better memory, attention and ability to do complex tasks
- People who had higher levels of Porphyromonas had more memory problems later
- People with a lot of Prevotella tended to predict poorer brain health and was more common in people who carry the Alzheimer’s Disease risk gene, APOE4.
If you’ve never heard of half of those, don’t worry: mostly your oral microbiome can take care of itself, provide you consistently do the things that create a “good” oral microbiome. So, see our “related” link below:

Weeding out a major cause of cognitive decline
Cannabis may be great for relaxation, but regular use is not great for mental sharpness, and recent use (even if not regular, and even if currently sober) shows a similar dip in cognitive abilities, especially working memory. In other words, cannabis use for relaxation should be at most an occasional thing, rather than an everyday thing.
While the results of the study are probably not shocking, something that we found interesting was their classification system:
❝Heavy users are considered young adults who’ve used cannabis more than 1000 times over their lifetime. Whereas, using 10 to 999 times was considered a moderate user, and fewer than 10 times was considered a non-user.❞
Which—while being descriptive rather than prescriptive in nature—suggests that, to be on the healthy end of the bell curve, an occasional cannabis-user might want to consider “if you have 999 uses before you hit the “heavy user” category, project those 999 uses against your life expectancy, and moderate your use accordingly”. In other words, a person just now starting use, who expects to live another 40 years, would calculate: 999/40 = 24.9 uses per year, so call it 2 per month. A person who only expects to live another 20 years, would do the same math and arrive at 4 per month.
Disclaimer: the above is intended as an interesting reframe, and a way of looking at long-term cannabis use while being mindful of the risks. It is not intended as advice. This health-conscious writer personally has no intention of using at all, unless perhaps in some bad future scenario in which I have bad chronic pain, I might consider that pain relief effects may be worth the downsides. Or I might not; I hope not to be in the situation to find out!

Mind-reading technology improves again
We’ve come quite a way from simple 1/0 reads, and basic cursor control! Now, researchers have created a brain decode that can translate a person’s thoughts into continuous text, without requiring the person to focus on words—in other words, it verbalizes the ideas directly. Most recently, the latest upgrade means that while previously, the device had to be trained on an individual brain for many hours, now the training/calibration process takes only an hour:

“I Stretched Every Day For 30 Days: Game Changer!”
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.
How much can an unflexible person really improve in just 20 minutes per day for a month? Makari Espe finds out:
Consistency really is key
We’re supposed to stretch at least 3 times per week; for many people, the reality is often more like 2 times per year (often the 1st and 2nd of January).
So, how quickly can such neglect be turned around?
Upon initial testing, she found she was even less flexible than thought, and set about her work:
The stretches she used were from random 20-minute full body stretch videos on YouTube, of which there are many, but she used a different one each day. As she went along, she found some favorite kinds of stretching and some favorite instructors, and settled on mostly Peloton stretching videos—she also switched to evening stretching sessions instead of morning.
Along the way, she already noticed gradual improvement in mobility and reduced body tension, and after 3 weeks, it had become a habit that she started craving.
The final test? There’s a marked improvement; see the video:
