AI: The Doctor That Never Tires?
We asked you for your opinion on the use of Artificial Intelligence (AI) in healthcare, and got the above-depicted, below-described set of results:
- A little over half of respondents to the poll voted for “It speeds up research, and is more methodical about diagnosis, so it’s at least a good extra tool”
- A quarter of respondents voted for “I’m on the fence—it seems to make no more nor less mistakes than human doctors do”
- A little under a fifth of respondents voted for “AI is less prone to fatigue/bias than human doctors, making it an essential new tech”
- Three respondents voted for “AI is a step too far in medical technology, and we’re not ready for it”
Writer’s note: I’m a professional writer (you’d never have guessed, right?) and, apparently, I really did write “no more nor less mistakes”, despite the correct grammar being “no more nor fewer mistakes”. Now, I know this, and in fact, people getting less/fewer wrong is a pet hate of mine. Nevertheless, I erred.
Yet, now that I’m writing this out in my usual software, and not directly into the poll-generation software, my (AI!) grammar/style-checker is highlighting the error for me.
Now, an AI could not do my job. ChatGPT would try, and fail miserably. But can technology help me do mine better? Absolutely!
And still, I dismiss a lot of the AI’s suggestions, because I know my field and can make informed choices. I don’t follow it blindly, and I think that’s key.
AI is less prone to fatigue/bias than human doctors, making it an essential new tech: True or False?
True—with one caveat.
First, a quick anecdote from a subscriber who selected this option in the poll:
❝As long as it receives the same data inputs as my doctor (ie my entire medical history), I can see it providing a much more personalised service than my human doctor who is always forgetting what I have told him. I’m also concerned that my doctor may be depressed – not an ailment that ought to affect AI! I recently asked my newly qualified doctor goddaughter whether she would prefer to be treated by a human or AI doctor. No contest, she said – she’d go with AI. Her argument was that human doctors leap to conclusions, rather than properly weighing all the evidence – meaning AI, as long as it receives the same inputs, will be much more reliable❞
Now, an anecdote is not data, so what does the science say?
Well… It says the same:
❝Of 6695 responding physicians in active practice, 6586 provided information on the areas of interest: 3574 (54.3%) reported symptoms of burnout, 2163 (32.8%) reported excessive fatigue, and 427 (6.5%) reported recent suicidal ideation, with 255 of 6563 (3.9%) reporting a poor or failing patient safety grade in their primary work area and 691 of 6586 (10.5%) reporting a major medical error in the prior 3 months. Physicians reporting errors were more likely to have symptoms of burnout (77.6% vs 51.5%; P<.001), fatigue (46.6% vs 31.2%; P<.001), and recent suicidal ideation (12.7% vs 5.8%; P<.001).❞
See the damning report for yourself: Physician Burnout, Well-being, and Work Unit Safety Grades in Relationship to Reported Medical Errors
AI, of course, does not suffer from burnout, fatigue, or suicidal ideation.
So, what was the caveat?
The caveat is about bias. Humans are biased, and that goes for medical practitioners just the same. AI’s machine learning is based on source data, and the source data comes from humans, who are biased.
See: Bias and Discrimination in AI: A Cross-Disciplinary Perspective
So, AI can perpetuate human biases and doesn’t have a special extra strength in this regard.
The lack of burnout, fatigue, and suicidal ideation, however, make a big difference.
AI speeds up research, and is more methodical about diagnosis: True or False?
True! AI is getting more and more efficient at this, and as has been pointed out, doesn’t make errors due to fatigue, and often comes to accurate conclusions near-instantaneously. To give just one example:
❝Deep learning algorithms achieved better diagnostic performance than a panel of 11 pathologists participating in a simulation exercise designed to mimic routine pathology workflow; algorithm performance was comparable with an expert pathologist interpreting whole-slide images without time constraints. The area under the curve was 0.994 (best algorithm) vs 0.884 (best pathologist).❞
About that “getting more and more efficient at this”; it’s in the nature of machine learning that every new piece of data improves the neural net being used. So long as it is getting fed new data, which it can process at rate far exceeding humans’ abilities, it will always be constantly improving.
AI makes no more nor less fewer mistakes than humans do: True or False?
False! AI makes fewer, now. This study is from 2021, and it’s only improved since then:
❝Professionals only came to the same conclusions [as each other] approximately 75 per cent of the time. More importantly, machine learning produced fewer decision-making errors than did all the professionals❞
See: AI can make better clinical decisions than humans: study
All that said, we’re not quite at Star Trek levels of “AI can do a human’s job entirely” just yet:
BMJ | Artificial intelligence versus clinicians: pros and cons
To summarize: medical AI is a powerful tool that:
- Makes healthcare more accessible
- Speeds up diagnosis
- Reduces human error
…and yet, for now at least, still requires human oversights, checks and balances.
Essentially: it’s not really about humans vs machines at all. It’s about humans and machines giving each other information, and catching any mistakes made by the other. That way, humans can make more informed decisions, and still keep a “hand on the wheel”.

The Simple Six – by Clinton Dobbins
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 at 10almonds don’t believe in keeping things a mystery, so…
“The Simple Six” are:
- the squat
- the goblet squat
- the hinge
- the kettlebell swing
- the push
- the push-up
- the kettle-bell press
- the pull
- the chin-up
- the gait, and
- walking.
Ok, we’re being a little glib here because to be fair, those are chunked into six groups, but the point is: don’t let the title fool you into thinking the book could have been an article; there’s plenty of valuable content here.
That said, it is a short book (64 pages), but with an average of 10 pages per exercise type, it’s a lot more than for example we could ever put into our newsletter.
Bottom line: we know that 10almonds readers like simple, clear, evidence-based, to-the-point health information, and that’s what this book is, so we do recommend it.

Entertaining Harissa Traybake
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.
No, it’s not entertaining in the sense that it will tell you jokes or perhaps dance for you, but rather: it can be easily prepared in advance, kept in the fridge for up to 3 days, and reheated when needed as part of a spread when entertaining, leaving you more time to spend with your houseguests.
Aside from its convenience, it is of course nutritious and delicious:
You will need
- 14 oz cherry tomatoes
- 2 cans chickpeas, drained and rinsed (or 2 cups cooked chickpeas, drained and rinsed)
- 2 eggplants, cut into ¾” cubes
- 1 red onion, roughly chopped
- 1 bulb garlic
- 2 tbsp extra virgin olive oil
- 1 tbsp harissa paste
- 1 tbsp ras el-hanout
- 1 tsp MSG or 2 tsp low-sodium salt
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 400℉ / 200℃
2) Mix the onion, eggplant, and garlic (whole cloves; just peel them and put them in) with the olive oil in a mixing bowl, ensuring everything is coated evenly.
3) Add in 1 tbsp of the harissa paste, 1 tbsp of the ras-el hanout, and half of the MSG/salt, and again mix thoroughly to coat evenly.
4) Bake in the oven, in a walled tray, for about 30 minutes, giving things a stir/jiggle halfway through to ensure they cook evenly.
5) Add the cherry tomatoes to the tray, and return to the oven for another 10 minutes.
6) Mix the chickpeas with the other 1 tbsp of the harissa paste, the other 1 tbsp of the ras-el hanout, and the other half of the MSG/salt, and add to the tray, returning it to the oven for a final 10 minutes.
7) Serve hot, or set aside for later, refrigerating once cool enough to do so. When you do serve, we recommend serving with a yogurt, cucumber, and mint dip, and perhaps flatbreads (you can use our Healthy Homemade Flatbreads recipe):
Enjoy!

Pomegranate vs Cherries – 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 pomegranate to cherries, we picked the pomegranate.
Why?
In terms of macros, pomegranate is slightly higher in carbs, and/but 4x higher in fiber. That’s already a good start for pomegranates. Lest we be accused of cherry-picking, though, we’ll mention that pomegranate is also slightly higher in protein and fat, for what it’s worth—which is not a lot. As with most fruits, the protein and fat numbers are low importance next to the carb:fiber ratio.
When it comes to vitamins, pomegranate has more of vitamins B1, B2, B5, B6, B9. E. K, and choline. On the other hand, cherries have more of vitamins A and B3. The two fruits are equal in vitamin C. This all makes for a clear win for pomegranate.
In the category of minerals, pomegranate boasts more copper, magnesium, phosphorus, potassium, selenium, and zinc. In contrast, cherries have slightly more calcium. Another win for pomegranate.
Both of these fruits have beneficial polyphenols, each with a slightly different profile, but neither pressingly better than the other.
In short: as ever with healthy foods, enjoy both—diversity is good! But if you’re going to pick on, we recommend the pomegranate.

The Wim Hof Method – by Wim Hof
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.
In Wednesday’s main feature, we wrote about the Wim Hof Method, and/but only scratched the surface. Such is the downside of being a super-condensed newsletter! However, it does give us the opportunity to feature the book:
The Wim Hof Method is definitely loudly trumpeted as “up there” with Atomic Habits or How Not To Die in the category of “life-changing” books. Why?
Firstly, it’s a very motivational book. Hof is a big proponent of the notion “if you think you can or you think you can’t, you’re right” idea, practises what he preaches, and makes clear he’s not special.
Secondly, it’s backed up with science. While it’s not a science-heavy book and that’s not the main focus, there are references to studies. Where physiological explanations are given for how certain things work, those explanations are sound. There’s no pseudoscience here, which is especially important for a book of this genre!
What does the book have that our article didn’t? A good few things:
- More about Hof’s own background and where it’s taken him. This is generally not a reason people buy books (unless they are biographies), but it’s interesting nonetheless.
- A lot more advice, data, and information about Cold Therapy and how it can (and, he argues convincingly, should) be built into your life.
- A lot about breathing exercises that we just didn’t cover at all in our article, but is actually an important part of the Wim Hof Method.
- More about stepping through the psychological barriers that can hold us back.
Bottom line: this book offers benefits that stretch into many areas of life, from some simple habits that can be built.

How To Improve Your Heart Rate Variability
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’s your heart rate variability?
The hallmarks of a good, strong cardiovascular system include a medium-to-low resting heart rate (for adults: under 60 beats per minute is good; under 50 is typical of athletes), and healthy blood pressure (for adults: under 120/80, while still above 90/60, is generally considered good).
Less talked-about is heart rate variability, but it’s important too…
What is heart rate variability?
Heart rate variability is a measure of how quickly and easily your heart responds to changes in demands placed upon it. For example:
- If you’re at rest and then start running your fastest (be it for leisure or survival or anything in between), your heart rate should be able to jump from its resting rate to about 180% of that as quickly as possible
- When you stop, your heart rate should be able to shift gears back to your resting rate as quickly as possible
The same goes, to a commensurately lesser extent, to changes in activity between low and moderate, or between moderate and high.
- When your heart can change gears quickly, that’s called a high heart rate variability
- When your heart is sluggish to get going and then takes a while to return to normal after exertion, that’s called a low heart rate variability.
The rate of change (i.e., the variability) is measured in microseconds per beat, and the actual numbers will vary depending on a lot of factors, but for everyone, higher is better than lower.
Aside from quick response to crises, why does it matter?
If heart rate variability is low, it means the sympathetic nervous system is dominating the parasympathetic nervous system, which means, in lay terms, your fight-or-flight response is overriding your ability to relax.
See for example: Stress and Heart Rate Variability: A Meta-Analysis and Review of the Literature
This has a lot of knock-on effects for both physical and mental health! Your heart and brain will take the worst of this damage, so it’s good to improve things for them impossible.
This Saturday’s Life Hacks: how to improve your HRV!
Firstly, the Usual Five Things™:
- A good diet (that avoids processed foods)
- Good exercise (that includes daily physical activity—more often is more important than more intense!)
- Good sleep (7–9 hours of good quality sleep per night)
- Reduce or eliminate alcohol consumption (this is dose-dependent; any reduction is an improvement)
- Don’t smoke (just don’t)
Additional regular habits that help a lot:
- Breathing exercises, mindfulness, meditation
- Therapy, especially CBT and DBT
- Stress-avoidance strategies, for example:
- Get (and maintain) your finances in good order
- Get (and maintain) your relationship(s) in good order
- Get (and maintain) your working* life in good order
*Whatever this means to you. If you’re perhaps retired, or otherwise a home-maker, or even a student, the things you “need to do” on a daily basis are your working life, for these purposes.
In terms of simple, quick-fix, physical tweaks to focus on if you’re already broadly leading a good life, two great ones are:
- Exercise: get moving! Walk to the store even if you buy nothing but a snack or drink to enjoy while walking back. If you drove, make more trips with the shopping bags rather than fewer. If you like to watch TV, consider an exercise bike or treadmill to use while watching. If you have a partner, double-up and make it a thing you do together! Take the stairs instead of the elevator. Take the scenic route when walking someplace. Go to the bathroom that’s further away. Every little helps!
- Breathe: even just a couple of times a day, practice mindful breathing. Start with even just a minute a day, to get the habit going. What breathing exercise you do isn’t so important as that you do it. Notice your breathing; count how long each breath takes. Don’t worry about “doing it right”—you’re doing great, just observe, just notice, just slowly count. We promise that regular practice of this will have you feeling amazing

Matcha is having a moment. What are the health benefits of this green tea drink?
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.
Matcha has experienced a surge in popularity in recent months, leading to reports of global shortages and price increases.
If you haven’t been caught up in the craze, matcha is a powdered version of green tea. On a cafe menu you might see a hot or iced matcha latte, or even a matcha-flavoured cake or pastry. A quick google brings up countless recipes incorporating matcha, both sweet and savoury.
Retailers and cafe owners have suggested the main reasons for matcha’s popularity include its “instagrammable” looks and its purported health benefits.
But what are the health benefits of matcha? Here’s what the evidence says.
Rawpixel.com/Shutterstock First, what is matcha?
Matcha is a finely ground powder of green tea leaves, which come from the plant Camellia sinensis. This is the same plant used to make green and black tea. However, the production process differentiates matcha from green and black tea.
For matcha, the tea plant is grown in shade. Once the leaves are harvested, they’re steamed and dried and the stems are removed. Then the leaves are carefully ground at controlled temperatures to form the powder.
The production process for green tea is simpler. The leaves are picked from the unshaded plants, heated and then dried. We then steep the dried leaves in hot water to get tea (whereas with matcha the whole leaf is consumed).
With black tea, after the leaves are picked they’re exposed to air, which leads to oxidation. This makes the leaves black and gives the tea a different flavour.
In countries such as Japan, matcha is traditionally whisked with water and served in a stone bowl. Charlotte May/Pexels A source of phytonutrients
Phytonutrients are chemical compounds found in plants which have a range of benefits for human health. Matcha contains several.
Chlorophyll gives plants such as Camellia sinensis their green colour. There’s some evidence chlorophyll may have health benefits – including anti-inflammatory, anti-cancer and anti-obesity effects – due to its antioxidant properties. Antioxidants neutralise free radicals, which are unstable molecules that harm our cells.
Theanine has been shown to improve sleep and reduce stress and anxiety. The only other known dietary source of theanine is mushrooms.
Caffeine is a phytonutrient we know well. Aside from increasing alertness, caffeine has also demonstrated antioxidant effects and some protection against a range of chronic and neurodegenerative diseases. However, too much caffeine can have negative side effects.
Interestingly, shading the plants while growing appears to change the nutritional composition of the leaf and may lead to higher levels of these phytonutrients in matcha compared to green tea.
Another compound worth mentioning is called catechins, of which there are several different types. Matcha powder similarly has more catechins than green tea. They are strong antioxidants, which have been shown to have protective effects against bacteria, viruses, allergies, inflammation and cancer. Catechins are also found in apples, blueberries and strawberries.
What are the actual health benefits?
So we know matcha contains a variety of phytonutrients, but does this translate to noticeable health benefits?
A review published in 2023 identified only five experimental studies that have given matcha to people. These studies gave participants about 2–4g of matcha per day (equivalent to 1–2 teaspoons of matcha powder), compared to a placebo, as either a capsule, in tea or in foods. Matcha decreased stress and anxiety, and improved memory and cognitive function. There was no effect on mood.
A more recent study showed 2g of matcha in older people aged 60 to 85 improved sleep quality. However, in younger people aged 27 to 64 in another study, matcha had little effect on sleep.
A study in people with obesity found no difference in the weight loss observed between the matcha group and the control group. This study did not randomise participants, and people knew which group they had been placed in.
It could be hypothesised that given you consume all of the leaf, and given levels of some phytonutrients may be higher due to the growing conditions, matcha may have more nutritional benefits than green tea. But to my knowledge there has been no direct comparison of health outcomes from green tea compared to matcha.
Matcha has grown in popularity – but evidence for its health benefits is still limited. Usanee/Shutterstock There’s lots of evidence for green tea
While to date a limited number of studies have looked at matcha, and none compared matcha and green tea, there’s quite a bit of research on the health benefits of drinking green tea.
A systematic review of 21 studies on green tea has shown similar benefits to matcha for improvements in memory, plus evidence for mood improvement.
There’s also evidence green tea provides other health benefits. Systematic reviews have shown green tea leads to weight loss in people with obesity, lower levels of certain types of cholesterol, and reduced blood pressure. Green tea may also lower the risk of certain types of cancer.
So, if you can’t get your hands on matcha at the moment, drinking green tea may be a good way to get your caffeine hit.
Although the evidence on green tea provides us with some hints about the health benefits of matcha, we can’t be certain they would be the same. Nonetheless, if your local coffee shop has a good supply of matcha, there’s nothing to suggest you shouldn’t keep enjoying matcha drinks.
However, it may be best to leave the matcha croissant or cronut for special occasions. When matcha is added to foods with high levels of added sugar, salt and saturated fat, any health benefits that could be attributed to the matcha may be negated.
