Cardiac Failure Explained – by Dr. Warrick Bishop

The cover of this book makes it look like it’ll be a flashy semi-celebrity doctor keen to sell his personalized protocol, along with eleventy-three other books, but actually, what’s inside this one is very different:
We (hopefully) all know the basics of heart health, but this book takes it a lot further. Starting with the basics, then the things that it’s easy to feel like you should know but actually most people don’t, then into much more depth.
The format is much more like a university textbook than most pop-science books, and everything about the way it’s written is geared for maximum learning. The one thing it does keep in common with pop-science books as a genre is heavy use of anecdotes to illustrate points—but he’s just as likely to use tables, diagrams, callout boxes, emboldening of key points, recap sections, and so forth. And for the most part, this book is very information-dense.
Dr. Bishop also doesn’t just stick to what’s average, and talks a lot about aberrations from the norm, what they mean and what they do and yes, what to do about them.
On the one hand, it’s more information dense than the average reader can reasonably expect to need… On the other hand, isn’t it great to finish reading a book feeling like you just did a semester at medical school? No longer will you be baffled by what is going on in your (or perhaps a loved one’s) cardiac health.
Bottom line: if you’d like to know cardiac health inside out, this book is an excellent place to start.

The Counterintuitive Dos and Don’ts of Nail Health

It’s Q&A Day at 10almonds!
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
❝I take a vitamin supplement for strengthening my nails (particularly one of my big toes!) – but they are running out! What do you recommend for strengthening nails? What is/are the key ingredient(s)?❞
Vitamin-wise, biotin (vitamin B7) is an underrated and very important one. As a bonus, it’s really good for your hair too (hair and nails being made of fundamentally the same “stuff”. Because it has exceptionally low toxicity, it can be taken up to 10,000% of the NRV, so if shopping for supplements, a high biotin content is better than a low one.
A lot of products marketed as for “skin, hair, and nails” focus on vitamins A and E, which are good for the skin but aren’t so relevant for nails.
Nutritionally, getting plenty of protein (whatever form you normally take it is fine) is also important since keratin (as nails are made of) is a kind of protein.
Outside of nutritional factors, a few other considerations:
- Testosterone strengthens nails, and declining testosterone levels (as experienced by most men over the age of 45) can result in weaker nails. So for men over 45 especially, a diet that favors testosterone (think foods rich in magnesium and zinc) is good.
- Because estrogen doesn’t do for women’s nails what testosterone does for men’s nails, increasing our magnesium and zinc intake won’t help our nails (but it’s still good for other things, including energy levels in the day and good sleep at night, and most people are deficient in magnesium anyway)
- Those of us who enjoy painted nails would do well to let our nails go without polish sometimes, as it can dry them out. And, acrylic nails are truly ruinous to nail health, as are gel nails (the kind that use a UV lamp to harden them—which is also bad for the skin)
- When nails are brittle, it can be tempting to soak them to reduce their brittleness. However, this is actually counterproductive, as the water will leech nutrients from the nails, and by the time you’ve been out of the footbath (for example) for about an hour, your nails will bemore brittle than before you soaked them.
- Use a moisturizing lotion or nail-oil instead—bonus if it contains biotin, keratin, and/or other helpful nutrients.
- Keep yourself hydrated, too! Hydration that comes to your nails from the inside will deliver nutrients, rather than removing them.
About those supplements: we don’t sell them (or anything else) but for your convenience, here are some great ones (this writer takes pretty much the same, just a different brand because I’m in a different country):
Magnesium Gummies (600mg) & Biotin Gummies (10,000µg)
Enjoy!
❝I was wondering whether there were very simple, clear bullet points or instructions on things to be wary of in Yoga.❞
That’s quite a large topic, and not one that lends itself well to being conveyed in bullet points, but first we’ll share the article you sent us when sending this question:
Tips for Avoiding Yoga Injuries
…and next we’ll recommend the YouTube channel @livinleggings, whose videos we feature here from time to time. She (Liv) has a lot of good videos on problems/mistakes/injuries to avoid.
Here’s a great one to get you started:

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.

10almonds Subcribers Take The Wheel!

❓ Q&A With 10almonds Subscribers!
Q: What kind of salt is best for neti pots?
A: Non-iodised salt is usually recommended, but really, any human-safe salt is fine. By this we mean for example:
- Sodium chloride (like most kitchen salts),
- Potassium chloride (as found in “reduced sodium” kitchen salts), or
- Magnesium sulfate (also known as epsom salts).
Q: You talked about spearmint as reducing testosterone levels, what about ginseng for increasing them?
A: Hormones are complicated and often it’s not a simple matter of higher or lower levels! It can also be a matter of…
- how your body converts one thing into another
- how your body responds (or not) to something according to how the relevant hormone’s receptors are doing
- …and whether there’s anything else blocking those receptors.
All this to say: spearmint categorically is an anti-androgen, but the mechanism of action remains uncertain.
Panax ginseng, meanwhile, is one of the most well-established mysteries in herbal medicine.
Paradoxically, it seems to improve both male and female hormonal regulation, despite being more commonly associated with the former.
- It doesn’t necessarily increase or decrease testosterone or estrogen levels (but it can, even if indirectly)
- It does improve sexual function
- …and alleviates symptoms associated with conditions as varied as:
- Late-onset hypogonadism (common for men during the andropause)
- Benign prostate hyperplasia (again common for men during the andropause)
- …and also counteracts unwanted side-effects of finasteride. Finasteride is often taken by men as a hair loss remedy or, less often but critically, in the case of an enlarged prostate.
But it also…
- Alleviates symptoms of PCOS (polycystic ovary syndrome, which effects around 20% of women)
- May even be an effective treatment for PCOS (rat model only so far)
- It also may improve female reproductive fertility more generally (the studies are down to fruit flies now though)
Bottom line: Panax ginseng is popularly taken to improve natural hormone function, a task at which it appears to excel.
Scientists are still working out exactly how it does the many things it appears to do.
Progress has been made, and it clearly is science rather than witchcraft, but there are still far more unanswered questions than resolved ones!
Q: I like that the quizzes (I’ve done two so far) give immediate results , with no “give us your email to get your results”. Thanks!
A: You’re welcome! That’s one of the factors that influences what things we include here! Our mission statement is “to make health and productivity crazy simple”, and the unwritten part of that is making sure to save your time and energy wherever we reasonably can!
Q: Do you know if adrafanil is as good as modafinil? It seems to be a lot cheaper for the same result?
A: Adrafinil is the pro-drug of modafinil. What this means is that if you take it, your own liver will use it to make modafinil inside you. So the end result is chemically the same drug.
As to whether it’s as good, it depends what you need. It’s worth noting that anything that taxes liver function can be harmful if you take too much, and/or your liver is already strained for some reason.
If in doubt, consult a doctor! And if it’s something that’s accessible to you, a recent lipids test (a kind of blood test that checks your liver health) is always a good thing to have.
Q: Would love to see your take on polyphasic sleep!
A: Watch this space

Nanotechnology vs Alcohol Damage!
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.
One Thing That Does Pair Well With Alcohol…
Alcohol is not a healthy thing to consume. That shouldn’t be a controversial statement, but there is a popular belief that it can be good for the heart:
Red Wine & The Heart: Can We Drink To Good Health?
The above is an interesting and well-balanced article that examines the arguments for health benefits (including indirectly, e.g. social aspects).
Ultimately, though, as the World Health Organization puts it:
WHO: No level of alcohol consumption is safe for our health
There is some good news:
We can somewhat reduce the harm done by alcohol by altering our habits slightly:
How To Make Drinking Less Harmful
…and we can also, of course, reduce our alcohol consumption (ideally to zero, but any reduction is an improvement already):
And, saving the best news (in this section, anyway) for last, it is almost always possible to undo the harm done specifically to one’s liver:
Nanotechnology to the rescue?
Remember when we had a main feature about how colloidal gold basically does nothing by itself (and that that’s precisely why gold is used in medicine, when it is used)?
Now it has an extra bit of nothing to do, for our benefit (if we drink alcohol, anyway), as part of a gel that detoxifies alcohol before it can get to our liver:
Gold is one of the “ingredients” in a gel containing a nanotechnology lattice of protein fibrils coated with iron (and the gold is there as an inert catalyst, which is chemistry’s way of saying it doesn’t react in any way but it does cheer the actual reagents on). There’s more chemistry going on than we have room to discuss in our little newsletter, so if you like the full details, you can read about that here:
Single-site iron-anchored amyloid hydrogels as catalytic platforms for alcohol detoxification
The short and oversimplified explanation is that instead of alcohol being absorbed from the gut and transported via the bloodstream to the liver, where it is metabolized (poisoning the liver as it goes, and poisoning the rest of the body too, including the brain), the alcohol is degraded while it is still in the gastrointestinal tract, converted by the gel’s lattice into acetic acid (which is at worst harmless, and actually in moderation a good thing to have).
Even shorter and even more oversimplified: the gel turns the alcohol into vinegar in the stomach and gut, before it can get absorbed into the blood.
But…
Of course there’s a “but”…
There are some limitations:
It doesn’t get it all (tests so far found it only gets about half of the alcohol), and so far it’s only been tested on mice, so it’s not on the market yet—while the researchers are sufficiently confident about it that a patent application has now been made, though, so it’ll probably show up on the market in the near future.
You can read a pop-science article about it (with diagrams!) here:
New gel breaks down alcohol in the body
Want to read more…
…about how to protect your organs (including your brain) from alcohol completely?
We’ve reviewed quite a number of books about quitting alcohol, so it’s hard to narrow it down to a single favorite, but after some deliberation, we’ll finish today with recommending:

The Science of Nutrition – by Rhiannon Lambert
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 there are a lot of conflicting dietary approaches out there, the science itself is actually fairly cohesive in most regards. This book does a lot of what we do here at 10almonds, and presents the science in a clear fashion without having any particular agenda to push.
The author is a nutritionist (BSc, MSc, RNutr) and therefore provides an up-to-date evidence-based approach for eating.
As a result, the only part of this book that brings it down in this reviewer’s opinion is the section on Intermittent Fasting. Being not strictly about nutrition, she has less expertise on that topic, and it shows.
The information is largely presented in double-page spreads each answering a particular question. Because of this, and the fact there are colorful graphic representations of information too, we do recommend the print version over Kindle*.
Bottom line: if you like the notion of real science being presented in a clear and simple fashion (we like to think our subscribers do!), then you’ll surely enjoy this book.
Click here to check out the Science of Nutrition, and get a clear overview!
*Writer’s note: I realize I’ve two days in a row recommended this (yesterday because there are checkboxes to check, worksheets to complete, etc), but it’s not a new trend; just how it happened to be with these two books. I love my Kindle dearly, but sometimes print has the edge for one reason or another!

Peace Is Every Step – by Thích Nhất Hạnh
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.
Mindfulness is one of the few practices to make its way from religion (in this case, Buddhism) into hard science. We’ve written before about its many evidence-based benefits, and many national health information outlets recommend it. So, what does this book have to add?
Thích Nhất Hạnh spent most of his 95 years devoted to the practice and teaching of mindfulness and compassion. In this book, the focus is on bringing mindfulness off the meditation mat and into general life.
After all, what if we could extend that “unflappability” into situations that pressure and antagonize us? That would be some superpower!
The author offers techniques to do just that, simple exercises to transform negative emotions, and to make us more likely to remember to do so.
After all, “in the heat of the moment” is rarely when many of us are at our best, this book gives way to allow those moments themselves to serve as immediate triggers to be our best.
The title “Peace Is Every Step” is not a random collection of words; the goal of this book is to enable to reader to indeed carry peace with us as we go.
Not just “peace is always available to us”, but if we do it right: “we have now arranged for our own peace to automatically step in and help us when we need it most”.
Bottom line: if you’d like to practice mindfulness, or practice it more consistently, this book offers some powerful tools.
