The brain is an amazing and powerful organ, with theoretically unlimited potential in some respects. So why doesn’t it feel that way a lot of the time?
The truth is that not only are we often tired, dehydrated, or facing other obvious physiological challenges to peak brain health, but also… We’re simply not making the best use of it!
What Dr. Davis does is outline for us how we can create the conditions for “two awesome hours” of effective mental performance by:
- Recognizing when to most effectively flip the switch on our automatic thinking
- Scheduling tasks based on their “processing demand” and recovery time
- Learning how to direct attention, rather than avoid distractions
- Feeding and moving our bodies in ways that prep us for success
- Identifying what matters in our environment to be at the top of our mental game
Why only two hours? Why not four, or eight, or more?
Well, our brains need recovery time too, so we can’t be “always on” and operating and peak efficiency. But, what we can do is optimize a couple of hours for absolute peak efficiency, and then enjoy the rest of time with lower cognitive-load activities.
Bottom line: if the idea of what you could accomplish if you could just be guaranteed two schedulable hours (your preference when!) of peak cognitive performance per day, then this is a great book for you.

This writer does too
We’ve previously reviewed her book, “Science of HIIT”, and we’re going to be talking a bit about High Intensity Interval Training today.
If you’d like to know a little more about the woman herself first, then…
Centr | Meet Ingrid: Your HIIT HIRT trainer
Yes, that is Centr, as in Chris Hemsworth’s personal training app, where Clay is the resident HIIT & HIRT expert & trainer.
What’s this HIIT & HIRT?
“HIIT” is High Intensity Interval Training, which we’ve written about before:
How To Do HIIT (Without Wrecking Your Body)
Basically, it’s a super-efficient way of working out, that gets better results than working out for longer with other methods, especially because of how it raises the metabolism for a couple of hours after training (this effect is called EPOC, by the way—Excessive Post-exercise Oxygen Consumption), and is a good thing.
You can read more about the science of it, in the above-linked main feature.
And HIRT?
“HIRT” is High Intensity Resistance Training, and is resistance training performed with HIIT principles.
See also: Chris Hemsworth’s Trainer Ingrid Clay Explains HIRT
An example is doing 10 reps of a resistance exercise (e.g., a dumbbell press) every minute on odd-numbered minutes, and 10 reps of a different resistance exercise (e.g. dumbbell squats) on even-numbered minutes.
If dumbbells aren’t your thing, it could be resistance bands, or even the floor (press-ups are a resistance exercise!)
For HIRT that’s not also a cardio exercise, gaps between different exercises can be quite minimal, as we only need to confuse the muscles, not the heart. So, effectively, it becomes a specially focused kind of circuit training!

What’s the difference between vegan and vegetarian?
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.
Vegan and vegetarian diets are plant-based diets. Both include plant foods, such as fruits, vegetables, legumes and whole grains.
But there are important differences, and knowing what you can and can’t eat when it comes to a vegan and vegetarian diet can be confusing.
So, what’s the main difference?
Creative Cat Studio/Shutterstock What’s a vegan diet?
A vegan diet is an entirely plant-based diet. It doesn’t include any meat and animal products. So, no meat, poultry, fish, seafood, eggs, dairy or honey.
What’s a vegetarian diet?
A vegetarian diet is a plant-based diet that generally excludes meat, poultry, fish and seafood, but can include animal products. So, unlike a vegan diet, a vegetarian diet can include eggs, dairy and honey.
But you may be wondering why you’ve heard of vegetarians who eat fish, vegetarians who don’t eat eggs, vegetarians who don’t eat dairy, and even vegetarians who eat some meat. Well, it’s because there are variations on a vegetarian diet:
- a lacto-ovo vegetarian diet excludes meat, poultry, fish and seafood, but includes eggs, dairy and honey
- an ovo-vegetarian diet excludes meat, poultry, fish, seafood and dairy, but includes eggs and honey
- a lacto-vegetarian diet excludes meat, poultry, fish, seafood and eggs, but includes dairy and honey
- a pescatarian diet excludes meat and poultry, but includes eggs, dairy, honey, fish and seafood
- a flexitarian, or semi-vegetarian diet, includes eggs, dairy and honey and may include small amounts of meat, poultry, fish and seafood.
Are these diets healthy?
A 2023 review looked at the health effects of vegetarian and vegan diets from two types of study.
Observational studies followed people over the years to see how their diets were linked to their health. In these studies, eating a vegetarian diet was associated with a lower risk of developing cardiovascular disease (such as heart disease or a stroke), diabetes, hypertension (high blood pressure), dementia and cancer.
For example, in a study of 44,561 participants, the risk of heart disease was 32% lower in vegetarians than non-vegetarians after an average follow-up of nearly 12 years.
Further evidence came from randomised controlled trials. These instruct study participants to eat a specific diet for a specific period of time and monitor their health throughout. These studies showed eating a vegetarian or vegan diet led to reductions in weight, blood pressure, and levels of unhealthy cholesterol.
For example, one analysis combined data from seven randomised controlled trials. This so-called meta-analysis included data from 311 participants. It showed eating a vegetarian diet was associated with a systolic blood pressure (the first number in your blood pressure reading) an average 5 mmHg lower compared with non-vegetarian diets.
It seems vegetarian diets are more likely to be healthier, across a number of measures.
For example, a 2022 meta-analysis combined the results of several observational studies. It concluded a vegetarian diet, rather than vegan diet, was recommended to prevent heart disease.
There is also evidence vegans are more likely to have bone fractures than vegetarians. This could be partly due to a lower body-mass index and a lower intake of nutrients such as calcium, vitamin D and protein.
But it can be about more than just food
Many vegans, where possible, do not use products that directly or indirectly involve using animals.
So vegans would not wear leather, wool or silk clothing, for example. And they would not use soaps or candles made from beeswax, or use products tested on animals.
The motivation for following a vegan or vegetarian diet can vary from person to person. Common motivations include health, environmental, ethical, religious or economic reasons.
And for many people who follow a vegan or vegetarian diet, this forms a central part of their identity.
More than a diet: veganism can form part of someone’s identity. Shutterstock So, should I adopt a vegan or vegetarian diet?
If you are thinking about a vegan or vegetarian diet, here are some things to consider:
- eating more plant foods does not automatically mean you are eating a healthier diet. Hot chips, biscuits and soft drinks can all be vegan or vegetarian foods. And many plant-based alternatives, such as plant-based sausages, can be high in added salt
- meeting the nutrient intake targets for vitamin B12, iron, calcium, and iodine requires more careful planning while on a vegan or vegetarian diet. This is because meat, seafood and animal products are good sources of these vitamins and minerals
- eating a plant-based diet doesn’t necessarily mean excluding all meat and animal products. A healthy flexitarian diet prioritises eating more whole plant-foods, such as vegetables and beans, and less processed meat, such as bacon and sausages
- the Australian Dietary Guidelines recommend eating a wide variety of foods from the five food groups (fruit, vegetables, cereals, lean meat and/or their alternatives and reduced-fat dairy products and/or their alternatives). So if you are eating animal products, choose lean, reduced-fat meats and dairy products and limit processed meats.

Gut-Healthy Tacos
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.
Full of prebiotics and probiotics, healthy fats, colorful salad boasting vitamins and minerals aplenty, and of course satisfying protein too, these tacos are also boasting generous flavors to keep you coming back for more…
You will need
- 24 sardines—canned is fine (if vegetarian/vegan, substitute tempeh and season generously; marinade if you have time)
- 12 small wholewheat tortillas
- 1 14oz/400g can black beans, drained
- 1 ripe avocado, stoned and cut into small chunks
- 1 red onion, thinly sliced
- 1 little gem lettuce, shredded
- 12 cherry tomatoes, halved
- 1 bulb garlic, crushed
- 1 lemon, sliced
- 4 tbsp plain unsweetened yogurt (your choice what kind, but something with a live culture is best)
- 3oz pickled jalapeños, roughly chopped
- 1oz cilantro (or substitute parsley if you have the cilantro-tastes-like-soap gene), finely chopped
- 1 tbsp extra virgin olive oil
- 2 tsp black pepper
- 1 tsp smoked paprika
- Juice of 1 lime
- Optional: Tabasco sauce, or similar hot sauce
Method
(we suggest you read everything at least once before doing anything)
1) Preheat your oven to a low temperature; 200℉ or just under 100℃ is fine
2) Place the lemon slices on top of the sardines on top of foil on a baking tray; you want the foil to be twice as much as you’d expect to need, because now you’re going to fold it over and make a sort of sealed envelope. You could use a dish with a lid yes, but this way is better because there’s going to be less air inside. Upturn the edges of the envelope slightly so that juices won’t run out, and make sure the foil is imperfectly sealed so a little steam can escape but not much at a time. This will ensure it doesn’t dry out, while also ensuring your house doesn’t smell of fish. Put all this into the oven on a middle shelf.
3) Mix the lime juice with the onion in a bowl, and add the avocado and tomatoes, mixing gently. Add half the cilantro, and set aside.
4) Put the black beans in a sieve and pour boiling water over them to refresh and slightly warm them. Tip them into a bowl and add the olive oil, black pepper, and paprika. Mix thoroughly with a fork, and no need to be gentle this time; in fact, deliberately break the beans a little in this case.
5) Mix the yogurt, jalapeños, garlic, and remaining cilantro in a small bowl.
6) Get the warmed sardines from the oven; discard the lemon slices.
7) Assemble! We recommend the order: tortilla, lettuce, fish (2 per taco), black bean mixture, salad mixture, garlic jalapeño yogurt mixture. You can also add a splash of the hot sauce per your preference, or if catering for more people, let people add their own.
Enjoy!

Undo It! – by Dr. Dean Ornish & Anne Ornish
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.
Of course, no lifestyle changes will magically undo Type 1 Diabetes or Cerebral Palsy.But for many chronic diseases, a lot can be done. The question is,how does one book cover them all?
As authors Dr. Dean Ornish and Anne Ornish explain, very many chronic diseases are exacerbated, or outright caused, by the same factors:
- Gene expression
- Inflammation
- Oxidative stress
This goes for chronic disease from heart disease to type 2 diabetes to cancer and many autoimmune diseases.
We cannot change our genes, but we can change our gene expression (the authors explain how). And certainly, we can control inflammation and oxidative stress.
Then first part of the book is given over to dietary considerations. If you’re a regular 10almonds reader, you won’t be too surprised at their recommendations, but you may enjoy the 70 recipes offered.
Attention is also given to exercising in ways optimized to beat chronic disease, and to other lifestyle factors.
Limiting stress is important, but the authors go further when it comes to psychological and sociological factors. Specifically, what matters most to health, when it comes to intimacy and community.
Bottom line: this is a very good guide to a comprehensive lifestyle overhaul, especially if something recently has given you cause to think “oh wow, I should really do more to avoid xyz disease”.

HRT Side Effects & Troubleshooting
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.
This is Dr. Heather Hirsch. She’s a board-certified internist, and her clinical expertise focuses on women’s health, particularly in midlife and menopause, and its intersection with chronic diseases (ranging from things associated with sexual health, to things like osteoporosis and heart disease).
So, what does she want us to know?
HRT can be life-changingly positive, but it can be a shaky start
Hormone Replacement Therapy (HRT), and in this context she’s talking specifically about the most common kind, Menopausal Hormone Therapy (MHT), involves taking hormones that our body isn’t producing enough of.
If these are “bioidentical hormones” as used in most of the industrialized world and increasingly also in N. America, then this is by definition a supplement rather than a drug, for what it’s worth, whereas some non-bioidentical hormones (or hormone analogs, which by definition function similarly to hormones but aren’t the same thing) can function more like drugs.
We wrote a little about his previously:
Hormone Replacement Therapy: A Tale Of Two Approaches
For most people most of the time, bioidentical hormones are very much the best way to go, as they are not only more effective, but also have fewer side effects.
That said, even bioidentical hormones can have some undesired effects, so, how to deal with those?
Don’t worry; bleed happy
A reprise of (usually quite light) menstrual bleeding is the most common side effect of menopausal HRT.
This happens because estrogen affects* the uterus, leading to a build-up and shedding of the uterine lining.
*if you do not have a uterus, estrogen can effect uterine tissue. That’s not a typo—here we mean the verb “effect”, as in “cause to be”. It will not grow a new uterus, but it can cause some clumps of uterine tissue to appear; this means that it becomes possible to get endometriosis without having a uterus. This information should not be too shocking, as endometriosis is a matter of uterine tissue growing inconveniently, often in places where it shouldn’t, and sometimes quite far from the uterus (if present, or its usual location, if absent). However, the risk of this happening is far lower than if you actually have a uterus:
What you need to know about endometriosis
Back to “you have a uterus and it’s making you wish you didn’t”:
This bleeding should, however, be light. It’ll probably be oriented around a 28-day cycle even if you are taking your hormones at the same dose every day of the month, and the bleeding will probably taper off after about 6 months of this.
If the bleeding is heavier, all the time, or persists longer than 6 months, then speak to your gynecologist about it. Any of those three; it doesn’t have to be all three!
Bleeding outside of one’s normal cycle can be caused by anything from fibroids to cancer; statistically speaking it’s probably nothing too dire,but when your safety is in question, don’t bet on “probably”, and do get it checked out:
When A Period Is Very Late (i.e., Post-Menopause)
Dr. Hirsch recommends, as possible remedies to try (preferably under your gynecologist’s supervision):
- lowering your estrogen dose
- increasing your progesterone dose
- taking progesterone continuously instead of cyclically
And if you’re not taking progesterone, here’s why you might want to consider taking this important hormone that works with estrogen to do good things, and against estrogen to rein in some of estrogen’s less convenient things:
Progesterone Menopausal HRT: When, Why, And How To Benefit
(the above link contains, as well as textual information, an explanatory video from Dr. Hirsch herself)
Get the best of the breast
Calm your tits. Soothe your boobs. Destress your breasts. Hakuna your tatas. Undo the calamity beleaguering your mammaries.
Ok, more seriously…
Breast tenderness is another very common symptom when starting to take estrogen. It can worry a lot of people (à la “aagh, what is this and is it cancer!?”), but is usually nothing to worry about. But just to be sure, do also check out:
Keeping Abreast Of Your Cancer Risk: How To Triple Your Breast Cancer Survival Chances
Estrogen can cause feelings of breast fullness, soreness, nipple irritation, and sometimes lactation, but this later will be minimal—we’re talking a drop or two now and again, not anything that would feed a baby.
Basically, it happens when your body hasn’t been so accustomed to normal estrogen levels in a while, and suddenly wakes up with a jolt, saying to itself “Wait what are we doing puberty again now? I thought we did menopause? Are we pregnant? What’s going on? Ok, checking all systems!” and then may calm down not too long afterwards when it notes that everything is more or less as it should be already.
If this persists or is more than a minor inconvenience though, Dr. Hirsch recommends looking at the likely remedies of:
- Adjust estrogen (usually the cause)
- Adjust progesterone (less common)
- If it’s progesterone, changing the route of administration can ameliorate things
What if it’s not working? Is it just me?
Dr. Hirsch advises the most common reasons are simply:
- wrong formulation (e.g. animal-derived estrogen or hormone analog, instead of bioidentical)
- wrong dose (e.g. too low)
- wrong route of administration (e.g. oral vs transdermal; usually transdermal estradiol is most effective but many people do fine on oral; progesterone meanwhile is usually best as a pessary/suppository, but many people do fine on oral)
Writer’s example: in 2022 there was an estrogen shortage in my country, and while I had been on transdermal estradiol hemihydrate gel, I had to go onto oral estradiol valerate tablets for a few months, because that’s what was available. And the tablets simply did not work for me at all. I felt terrible and I have a good enough intuitive sense of my hormones to know when “something wrong is not right”, and a good enough knowledge of the pharmacology & physiology to know what’s probably happening (or not happening). And sure enough, when I got my blood test results, it was as though I’d been taking nothing. It was such a relief to get back on the gel once it became available again!
So, if something doesn’t seem to be working for you, speak up and get it fixed if at all possible.

Sweet Cinnamon vs Regular Cinnamon – 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 sweet cinnamon to regular cinnamon, we picked the sweet.
Why?
In this case, it’s not close. One of them is health-giving and the other is poisonous (but still widely sold in supermarkets, especially in the US and Canada, because it is cheaper).
It’s worth noting that “regular cinnamon” is a bit of a misnomer, since sweet cinnamon is also called “true cinnamon”. The other cinnamon’s name is formally “cassia cinnamon”, but marketers don’t tend to call it that, preferring to calling it simply “cinnamon” and hope consumers won’t ask questions about what kind, because it’s cheaper.
Note: this too is especially true in the US and Canada, where for whatever reason sweet cinnamon seems to be more difficult to obtain than in the rest of the world.
In short, both cinnamons contain cinnamaldehyde and coumarin, but:
- Sweet/True cinnamon contains only trace amounts of coumarin
- Regular/Cassia cinnamon contains about 250x more coumarin
Coumarin is heptatotoxic, meaning it poisons the liver, and the recommended safe amount is 0.1mg/kg, so it’s easy to go over that with just a couple of teaspoons of cassia cinnamon.
You might be wondering: how can they get away with selling something that poisons the liver? In which case, see also: the alcohol aisle. Selling toxic things is very common; it just gets normalized a lot.
Cinnamaldehyde is responsible for cinnamon’s healthier properties, and is found in reasonable amounts in both cinnamons. There is about 50% more of it in the regular/cassia than in the sweet/true, but that doesn’t come close to offsetting the potential harm of its higher coumarin content.
