The author, a professional gymnast and coach with a background in the sciences, knows his stuff here. This is what it says on the tin: it’s rigorously systematic. It’s also the most science-based calisthenics book this reviewer has read to date.
If you just wanted to know how to do some exercises, then this book would be very much overkill, but if you want to be able to go from no knowledge to expert knowledge, then the nearly 600 pages of this weighty tome will do that for you.
This is a textbook, it’s a “the bible of…” style book, it’s the one that if you’re serious, will engage you thoroughly and enable you to craft the calisthenics-forged body you want, head to toe.
As if it weren’t already overdelivering, it also has plenty of information on injury avoidance (or injury/condition management if you have some existing injury or chronic condition), and building routines in a dynamic fashion that avoids becoming a grind, because it’s going from strength to strength while cycling through different body parts.
Bottom line: if you’d like to get serious about calisthenics, then this is the book for you.

Chocolate & Health
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.
Chocolate & Health: Fact or Fiction?
“Chocolate Is Good For The Heart”
“When making chocolate chip cookies, you don’t measure using cups, you measure by heart”
…but how good is chocolate when it comes to heart health?
First, what is heart health?
A healthy heart typically has a low resting pulse rate and a strong, steady beat. This is affected strongly by exercise habits, and diet plays only a support role (can’t exercise without energy from food!).
It is also important to have blood pressure within a healthy range (with high blood pressure being a more common problem than low, so things that lower blood pressure are generally considered good).
- Flavanols, flavonoids, and polyphenols in chocolate contribute to lower blood pressure
- Dark chocolate is best for these, as milk chocolate contains much less cocoa solids and more unhelpful fats
- White chocolate contains no cocoa solids and is useless for this
- Some of the fats in most commercial chocolate can contribute to atherosclerosis which raises blood pressure and ultimately can cause heart attacks.
- If you’re diabetic, you will probably not get the usual heart-related benefits from chocolate (sorry)
The Verdict: dark chocolate, in moderation, can support good heart health.
“Chocolate Is Good For The Brain”
Chocolate has been considered a “brain food”… why?
- The brain uses more calories than any other organ (chocolate has many calories)
- The heart benefits we listed above mean improved blood flow—including to your brain
- Chocolate contains phenylethylamine, a powerful chemical that has a similar effect to amphetamines… But it’s metabolized in digestion and never makes it to the central nervous system (so basically, this one’s a miss; we had a good run with the other two, though!)
The Verdict: dark chocolate, in moderation, can support good brain health
“Chocolate Is An Aphrodisiac”
“If chocolate be the food of love, pass me that cocoa; I’m starving”
Most excitingly, chocolate contains phenylethylamine, the “molecule of love” or, more accurately, lust. It has an effect similar to amphetamines, and while we can synthesize it in the body, we can also get it from certain foods. But…
Our body is so keen to get it that most of it is metabolized directly during digestion and doesn’t make it to the brain. Also, chocolate is not as good a source as cabbage—do with that information what you will!
However!
Chocolate contains theobromine and small amounts of caffeine, both stimulants and both generally likely to improve mood; it also contains flavonoids which in turn stimulate production of nitric oxide, which is a relaxant. All in all, things that are convivial to having a good time.
On the other hand…
That relaxation comes specifically with a reduction in blood pressure—something typically considered good for the health for most people most of the time… but that means lowering blood pressure in all parts of your body, which could be the opposite of what you want in intimate moments.
Chocolate also contains zinc, which is essential for hormonal health for most people—the body uses it to produce testosterone and estrogen, respectively. Zinc supplements are popularly sold to those wishing to have more energy in general and good hormonal health in particular, and rightly so. However…
This approach requires long-term supplementation—you can’t just pop a zinc tablet / bar of chocolate / almond before bed and expect immediate results. And if your daily zinc supplementation takes the form of a 3.5oz (100g) bar of chocolate, then you may find it has more effects on your health, and not all of them good!
The Verdict: dark chocolate, in moderation, may promote “the mood”, but could be a double-edged sword when it comes to “the ability”.
“Chocolate Is Good During Menstruation”
The popular wisdom goes that chocolate is rich in iron (of which more is needed during menstruation), and indeed, if you eat 7oz (150g) of dark chocolate made with 85% cocoa, you’ll get a daily a dose of iron (…and nearly 1,000 calories).
More bang-for-buck dietary sources of iron include chickpeas and broccoli, but for some mysterious reason, these are not as commonly reported as popular cravings.
The real explanation for chocolate cravings is more likely that eating chocolate—a food high in sugar and fat along with a chemical bombardment of more specialized “hey, it’s OK, you can relax now” molecules (flavanols/flavonoids, polyphenols, phenylamines, even phenylethylamine, etc) gives a simultaneous dopamine kick (the body’s main “reward” chemical) with a whole-body physiological relaxation… so, little wonder we might crave it in times of stress and discomfort!
The Verdict: it helps, not because it serves a special nutritional purpose, but rather, because the experience of eating chocolate makes us feel good.
Fun fact: Tiramisu (this writer’s favorite dessert) is literally Italian for “pick-me-up”

Coca-Cola vs Diet Coke – 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 Coca-Cola to Diet Coke, we picked the Diet Coke.
Why?
While the Diet Coke is bad, the Coca-Cola has mostly the same problems plus sugar.
The sugar in a can of Coca-Cola is 39g high-fructose corn syrup (the worst kind of sugar yet known to humanity), and of course it’s being delivered in liquid form (the most bioavailable way to get, which in this case, is bad).
To put those 39g into perspective, the daily recommended amount of sugar is 36g for men or 25g for women, according to the AHA.
The sweetener in Diet Coke is aspartame, which has had a lot of health risk accusations made against it, most of which have not stood up to scrutiny, and the main risk it does have is “it mimics sugar too well” and it can increase cravings for sweetness, and therefore higher consumption of sugars in other products. For this reason, the World Health Organization has recommended to simply reduce sugar intake without looking to artificial sweeteners to help.
Nevertheless, aspartame has been found safe (in moderate doses; the upper tolerance level would equate to more than 20 cans of diet coke per day) by food safety agencies ranging from the FDA to the EFSA, based on a large body of science.
Other problems that Diet Coke has are present in Coca-Cola too, such as its acidic nature (bad for tooth enamel) and gassy nature (messes with leptin/ghrelin balance).
Summary: the Diet Coke is relatively less unhealthy, but is still bad in numerous ways, and remains best avoided.

Cold Weather Health Risks
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.
Many Are Cold; Few Are Frozen
Many of those of us in the Northern Hemisphere are getting hit with a cold spell around now. How severe that may be depends on more precisely where we are, but it’s affecting a lot of people. So, with apologies to our readers in Australia, we’re going to do a special on that today.
Acute cold is, for most people, good for the health:
A Cold Shower A Day Keeps The Doctor Away?
Persistent cold, not so much. Let’s look at the risks, and what can be done about them…
Hypothermia
It kills. Don’t let it kill you or your loved ones.
And, this is really important: it doesn’t care whether you’re on a mountain or not.
In other words: a lot of people understand (correctly!) that hypothermia is a big risk to hikers, climbers, and the like. But if the heating goes out in your house and the temperature drops for long enough before the heating is fixed, you can get hypothermia there too just the same if you’re not careful.
How cold is too cold? It doesn’t even have to be sub-zero. According to the CDC, temperatures of 4℃ (40℉) can be low enough to cause hypothermia if other factors combine:
CDC | Prevent Hypothermia & Frostbite ← you can also see the list of symptoms to watch out for, there!
Skin health
Not generally an existential risk, but we may as well stay healthy as not!
Cold air often means dry air, so use a moisturizer with an oil base (if you don’t care for fancy beauty products, ordinary coconut oil is top-tier).
Bonus if you do it after a warming bath/shower!
Heart health
Cold has a vasconstricting effect; that is to say, it causes the body’s vasculature to shrink, increasing localized blood pressure. If it’s a cold shower as above, that can be very invigorating. If it’s a week of sub-zero temperatures, it can become a problem.
❝Shoveling a little snow off your sidewalk may not seem like hard work. However, […] combined with the fact that the exposure to cold air can constrict blood vessels throughout the body, you’re asking your heart to do a lot more work in conditions that are diminishing the heart’s ability to function at its best.❞
Source: Snow shoveling, cold temperatures combine for perfect storm of heart health hazards
If you have a heart condition, please do not shovel snow. Let someone else do it, or stay put.
And if you are normally able to exercise safely? Unless you’re sure your heart is in good order, exercising in the warmth, not the cold, seems to be the best bet.

Immune health
We recently discussed how cold weather indirectly increases the risk of respiratory viral infection:
The Cold Truth About Respiratory Infections
So, now’s the time to be extra on-guard about that.

Balance
Icy weather increases the risk of falling. If you think “having a fall” is something that happens to other/older people, please remember that there’s a first time for everything. Some tips:
- Walk across icy patches with small steps in a flat-footed fashion like a penguin.
- It may not be glamorous, but neither is going A-over-T and breaking (or even just spraining) things.
- Use a handrail if available, even if you don’t think you need to.

Fruit & Veg In The Fridge: Pros & Cons
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.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
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
❝What effect does refrigeration have on the nutritional value of fruit and vegetables??❞
It’s difficult to give a single definitive answer, because naturally there are a lot of different fruits and vegetables, and a lot of different climates. The answer may be different for tomatoes in Alaska vs bananas in Arizona!
However, we can still generalize at least somewhat
Refrigeration will generally slow down any degradation process, and in the case of fruit and vegetables, that can mean slowing down their “ripening” too, as applicable.
However…
Refrigeration will also impede helpful bioactivity too, and that includes quite a list of things.
Here’s a good study that’s quite illustrative; we’d summarize the conclusions but the rather long title already does that nicely:
So, this really is a case of “there are pros and cons, but probably more cons on balance”.
In practical terms, a good take-away from this can be twofold:
- don’t keep fruit and veg in the fridge unless the ambient temperature really requires it
- if the ambient temperature does require it, it’s best to get the produce in fresh each day if that’s feasible, to minimize time spent in the fridge
An extra thing not included there: often when it comes to the spoilage of fruit and veg, the problem is that it respires and oxidizes; reducing the temperature does lower the rate of those, but often a far better way is to remove the oxygen. So for example, if you get carried away and chop too many carrot batons for your hummus night, then putting them in a sealed container can go a long way to keeping them fresh.

Eat Better, Feel Better – by Giada de Laurentis
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 yesterday’s edition of 10almonds, we reviewed Dr. Aujla’s “The Doctor’s Kitchen“; today we’re reviewing a different book about healing through food—in this case, with a special focus on maintaining energy and good health as we get older.
De Laurentis may not be a medical doctor, but she is a TV chef, and not only holds a lot of influence, but also has access to a lot of celebrity doctors and such; that’s reflected a lot in her style and approach here.
The recipes are clear and easy to follow; well-illustrated and nicely laid-out.
This cookbook’s style is less “enjoy this hearty dish of rice and beans with these herbs and spices” and more “you can serve your steak salad with white beans and sweet shallot dressing on a bed of organic quinoa if you haven’t already had your day’s serving of grains, of course”.
It’s a little fancier, in short, and more focused on what to cut out, than what to include. On account of that, this could make it a good contrast to yesterday’s book, which had the opposite focus.
She also recommends assorted adjuvant practices; some that are evidence-based, like intermittent fasting and meditation, and some that are not, like extreme detox-dieting, and acupuncture (which has no bearing on gut health).
Bottom line: if you like the idea of eating for good health, and prefer a touch of celebrity lifestyle to your meals, this one’s a good book for you.

The Spectrum of Hope – by Dr. Gayatri Devi
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 before about Dr. Devi’s work (See: “Alzheimer’s: The Bad News And The Good“) but she has plenty more to say than we could fit in an article.
The book is written for patients, family/carers, and clinicians—without getting deep into the science, which it is assumed clinicians will know. the general style of the book is pop-science, and it’s more about addressing the misconceptions around Alzheimer’s, rather than focusing on neurological features such as beta amyloid plaques and tau proteins and the like.
Dr. Devi explains a lot about the experience of Alzheimer’s—what to expect, or rather, what to know about in advance. Because, as she explains, there are a lot of different manifestations of Alzheimer’s that are all lumped under the same umbrella.
This means that a person could have negligible memory but perfect language and reasoning skills, or the other way around, or some other combination of symptoms showing up or not.
Which means that any plan for managing one’s Alzheimer’s needs to be adaptable and personalized, which is something Dr. Devi talks us through, too.
Bottom line: if you are a loved one has Alzheimer’s, or you just like to be prepared, this is a great book to prepare anybody for just that.
Click here to check out The Spectrum of Hope, and hold onto that hope!
