Inheritance – by Dr. Sharon Moalem

We know genes make a big difference to a lot about us, but how much? And, the genes we have, we’re stuck with, right?
Dr. Sharon Moalem shines a bright light into some of the often-shadowier nooks and crannies of our genetics, covering such topics as:
- How much can (and can’t) be predicted from our parents’ genes—even when it comes to genetic traits that both parents have, and Gregor Mendel himself would (incorrectly) think obvious
- How even something so seemingly simple and clear as genetic sex, very definitely isn’t
- How traumatic life events can cause epigenetic changes that will scar us for generations to come
- How we can use our genetic information to look after our health much better
- How our life choices can work with, or overcome, the hand we got dealt in terms of genes
The style of the book is conversational, down to how there’s a lot of “I” and “you” in here, and the casual style belies the heavy, sharp, up-to-date science contained within.
Bottom line: if you’d like insight into the weird and wonderful nuances of genetics as found in this real, messy, perfectly chaotic world, this book is an excellent choice.

Eat To Avoid (Or Beat) PCOS
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.
Polycystic ovary syndrome, PCOS, affects very many people; around 1 in 5 women. It can show up unexpectedly, and usually the first-identified sign is irregular vaginal bleeding. We say “vaginal” rather than “menstrual” as it’s not technically menses, although it’ll look (and can feel) the same.
Like many “affects mostly women” conditions, science’s general position is “we don’t know what causes it or how to cure it”.
Quick book recommendation before we continue:
Unwell Women: Misdiagnosis and Myth in a Man-Made World – by Dr. Elinor Cleghorn
…is a top-tier book about medical misogyny. We’d say more here, but well, you can read our review there 🙂
What doesn’t work
Since PCOS is characterized by excessive androgen production, it is reasonable to expect that foods containing phytoestrogens (such as soy) may help. They won’t. The human body can’t use those as estrogen, and in fact, consuming unusually large quantities of phytoestrogens can actually get in the way of your own (or bioidentical) estrogen, by competing for the same receptors but not really doing the job.
But, you won’t get that problem from moderate consumption of soy; the warning is more for those tempted to self-medicate with megadoses, or are opting for dubious supplements such as Pueraria mirifica ← will have to do a research review on that one of these days, but suffice it to say meanwhile, it has some serious drawbacks
See also: What Does “Balance Your Hormones” Even Mean?
What can work
There are some supplement-based approaches that actually can help, and those are the ones that rather than trying to manufacture estrogen out of thin air, work to reduce testosterone and/or reduce the conversion of free testosterone to its more potent form, dihydrogen testosterone (DHT); here are two examples:
- Licorice, Digestion, & Hormones
- One Man’s Saw Palmetto Is Another Woman’s Serenoa Repens ← this one has the most evidence of the two
What will work
…or at least, barring additional confounding factors, what the evidence strongly supports working. Here’s where we get into diet properly, and there are three main dietary approaches:
Low-GI diet: focus on high-fiber, low-carb foods (e.g. whole grains, legumes, berries, leafy greens). Eating this way results in improved insulin sensitivity, lower fasting insulin, cholesterol, triglycerides, waist circumference, and (for women) yes, lower testosterone levels.
See: What Do The Different Kinds Of Fiber Do? 30 Foods That Rank Highest
High antioxidant diet: focus on foods rich in antioxidants (e.g. vitamin A, α-tocopherol specifically, vitamins C and D, and polyphenols) as these lower PCOS incidence.
See: 21 Most Beneficial Polyphenols & What Foods Have Them
Ketogenic diet: focus on high-fat, very low-carb foods (e.g. fatty fish, dairy, leafy greens). This significantly reduces androgen levels, improves insulin sensitivity, and regulates hormones. But… It’s recommended for short-term use only due to its negative health impacts from poor (i.e. narrow) nutritional coverage:
See: Ketogenic Diet: Burning Fat, Or Burning Out?
It is also reasonable to supplement, for example:
❝Omega-3 fatty acids and vitamin D have powerful anti-inflammatory and antioxidant properties that significantly improve insulin sensitivity and reduce androgen levels in metabolic syndromes like PCOS. A higher intake of omega-3 and vitamin E also alleviates mental health parameters and gene expression of PPAR-γ, IL-8, and TNF-α in women with PCOS.
Dietary supplements, such as antioxidants like N-acetylcysteine (NAC), vitamin D, inositol, and omega-3 fatty acids, and mineral supplements (zinc, magnesium selenium, and chromium) help in reducing insulin resistance. These supplements also enhance ovulatory function and decrease inflammation in PCOS patients.
Omega-3 fatty acid supplements improve biochemical parameters LH, LH/FSH, lipid profiles, and adiponectin levels and regularize the menstrual cycle in women with PCOS. A recent RCT also indicated that probiotic/symbiotic supplementation significantly improves triglyceride, insulin, and HDL levels in women with PCOS.❞

Meditation for Fidgety Skeptics – by Dan Harris
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.
If you already meditate regularly, this book isn’t aimed at you (though you may learn a thing or two anyway—this reviewer, who has practiced meditation for the past 30 years, learned a thing!).
However, if you’re—as the title suggests—someone who hasn’t so far been inclined towards meditation, you could get the most out of this one. We’ll say more on this (obviously), but first, there’s one other group that may benefit from this book:
If you have already practiced meditation, and/or already understand and want its benefits, but never really made it stick as a habit.
Now, onto what you’ll get:
- A fair scientific overview of meditation as an increasingly evidence-based way to reduce stress and increase both happiness and productivity
- A good grounding in what meditation is and isn’t
- A how-to guide for building up a consistent meditation habit that won’t get kiboshed when you have a particularly hectic day—or a cold.
- An assortment of very common (and some less common) meditative practices to try
- Some great auxiliary tools to build cognitive restructuring into your meditation
We don’t usually cite other people’s reviews, but we love that one Amazon reviewer wrote:
❝I am 3 weeks into daily meditation practice, and I already notice that I am no longer constantly wishing for undercarriage rocket launchers while driving. I will always think your driving sucks, but I no longer wish you a violent death because of it. Yes, I live in Boston❞
Bottom line: if you’re not already meditating daily, this is definitely a book for you. And if you are, you may learn a thing or two anyway!

Okra vs Asparagus – 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 okra to asparagus, we picked the okra.
Why?
Both are great! But…
In terms of macros, okra has more fiber and carbs, making it the more nutrient dense option, for a similar glycemic index.
In the category of vitamins, okra has more of vitamins B1, B3, B6, B9, and C, while asparagus has more of vitamins B2, B5, E, K, and choline, making for a 5:5 tie, with similar margins of difference too. Thus, definitely a tie on vitamins.
When it comes to minerals, okra has more calcium, magnesium, manganese, phosphorus, potassium, and zinc, while asparagus has more copper, iron, and selenium. An easy 6:3 win for okra.
Both of these on-the-cusp-of-being-pungent vegetables have beneficial antioxidant polyphenols (especially various forms of quercetin), but okra has more.
Adding up the sections makes for an overall win for okra, but by all means enjoy either both; diversity is good!

Teriyaki Chickpea Burgers
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.
Burgers are often not considered the healthiest food, but they can be! Ok, so the teriyaki sauce component itself isn’t the healthiest, but the rest of this recipe is, and with all the fiber this contains, it’s a net positive healthwise, even before considering the protein, vitamins, minerals, and assorted phytonutrients.
You will need
- 2 cans chickpeas, drained and rinsed (or 2 cups of chickpeas, cooked drained and rinsed)
- ¼ cup chickpea flour (also called gram flour or garbanzo bean flour)
- ¼ cup teriyaki sauce
- 2 tbsp almond butter (if allergic, substitute with a seed butter if available, or else just omit; do not substitute with actual butter—it will not work)
- ½ bulb garlic, minced
- 1 large chili, minced (your choice what kind, color, or even whether or multiply it)
- 1 large shallot, minced
- 1″ piece of ginger, grated
- 2 tsp teriyaki sauce (we’re listing this separately from the ¼ cup above as that’ll be used differently)
- 1 tsp yeast extract (even if you don’t like it; trust us, it’ll work—this writer doesn’t like it either but uses it regularly in recipes like these)
- 1 tbsp black pepper
- 1 tsp fennel powder
- ½ tsp sweet cinnamon
- ½ tsp MSG or 1 tsp low-sodium salt
- Extra virgin olive oil for frying
For serving:
- Burger buns (you can use our Delicious Quinoa Avocado Bread recipe)
- Whatever else you want in there; we recommend mung bean sprouts, red onion, and a nice coleslaw
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 400℉ / 200℃.
2) Roast the chickpeas spaced out on a baking tray (lined with baking paper) for about 15 minutes. Leave the oven on afterwards; we still need it.
3) While that’s happening, heat a little oil in a skillet to a medium heat and fry the shallot, chili, garlic, and ginger, for about 2–3 minutes. You want to release the flavors, but not destroy them.
4) Let them cool, and when the chickpeas are done, let them cool for a few minutes too, before putting them all into a food processor along with the rest of the ingredients from the main section, except the oil and the ¼ cup teriyaki sauce. Process them into a dough.
5) Form the dough into patties; you should have enough dough for 4–6 patties depending on how big you want them.
6) Brush them with the teriyaki sauce; turn them onto a baking tray (lined with baking paper) and brush the other side too. Be generous.
7) Bake them for about 15 minutes, turn them (taking the opportunity to add more teriyaki sauce if it seems to merit it) and bake for another 5–10 minutes.
8) Assemble; we recommend the order: bun, a little coleslaw, burger, red onion, more coleslaw, mung bean sprouts, bun, but follow your heart!
Enjoy!

Why are my muscles sore after exercise? Hint: it’s nothing to do with lactic acid
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.
As many of us hit the gym or go for a run to recover from the silly season, you might notice a bit of extra muscle soreness.
This is especially true if it has been a while between workouts.
A common misunderstanding is that such soreness is due to lactic acid build-up in the muscles.
Research, however, shows lactic acid has nothing to do with it. The truth is far more interesting, but also a bit more complex.
It’s not lactic acid
We’ve known for decades that lactic acid has nothing to do with muscle soreness after exercise.
In fact, as one of us (Robert Andrew Robergs) has long argued, cells produce lactate, not lactic acid. This process actually opposes not causes the build-up of acid in the muscles and bloodstream.
Unfortunately, historical inertia means people still use the term “lactic acid” in relation to exercise.
Lactate doesn’t cause major problems for the muscles you use when you exercise. You’d probably be worse off without it due to other benefits to your working muscles.
Lactate isn’t the reason you’re sore a few days after upping your weights or exercising after a long break.
So, if it’s not lactic acid and it’s not lactate, what is causing all that muscle soreness?
Muscle pain during and after exercise
When you exercise, a lot of chemical reactions occur in your muscle cells. All these chemical reactions accumulate products and by-products which cause water to enter into the cells.
That causes the pressure inside and between muscle cells to increase.
This pressure, combined with the movement of molecules from the muscle cells can stimulate nerve endings and cause discomfort during exercise.
The pain and discomfort you sometimes feel hours to days after an unfamiliar type or amount of exercise has a different list of causes.
If you exercise beyond your usual level or routine, you can cause microscopic damage to your muscles and their connections to tendons.
Such damage causes the release of ions and other molecules from the muscles, causing localised swelling and stimulation of nerve endings.
This is sometimes known as “delayed onset muscle soreness” or DOMS.
While the damage occurs during the exercise, the resulting response to the injury builds over the next one to two days (longer if the damage is severe). This can sometimes cause pain and difficulty with normal movement.
The upshot
Research is clear; the discomfort from delayed onset muscle soreness has nothing to do with lactate or lactic acid.
The good news, though, is that your muscles adapt rapidly to the activity that would initially cause delayed onset muscle soreness.
So, assuming you don’t wait too long (more than roughly two weeks) before being active again, the next time you do the same activity there will be much less damage and discomfort.
If you have an exercise goal (such as doing a particular hike or completing a half-marathon), ensure it is realistic and that you can work up to it by training over several months.
Such training will gradually build the muscle adaptations necessary to prevent delayed onset muscle soreness. And being less wrecked by exercise makes it more enjoyable and more easy to stick to a routine or habit.
Finally, remove “lactic acid” from your exercise vocabulary. Its supposed role in muscle soreness is a myth that’s hung around far too long already.

Treat Your Own Hip – by Robin McKenzie
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 previously reviewed another book by this author in this series, “Treat Your Own Knee”, and today it’s the same deal, but for the hip.
A quick note about the author first: a physiotherapist and not a doctor, but with over 40 years of practice to his name and 33 letters after his name (CNZM OBE FCSP (Hon) FNZSP (Hon) Dip MDT Dip MT), he seems to know his stuff.
He takes the reader through first diagnosing the nature of the pain (and how to rule out, for example, a back problem manifesting as hip pain, rather than a hip problem per se—and points to his own “Treat Your Own Back” manual if it turns out that that’s your problem instead), and then treating it. A bold claim, the kind that many people’s lawyers don’t let them make, but once again, this guy is pretty much the expert when it comes to this. Ask any other physiotherapist, and they probably have several of his books on their shelf.
The treatments recommend are tailored to the results of various diagnostic flowcharts; essentially troubleshooting your hip. However, they mainly consist of exercises (perhaps the greatest value of the book), and lifestyle adjustments (these ones, 10almonds readers probably know already, but a reminder never hurts).
The explanations are thorough while still being comprehensible, and there is zero sensationalization or fluff. It is straight to the point, and clearly illustrated too with diagrams and photographs.
Bottom line: if you’re looking for a “one-stop shop” for diagnosing and treating your bad hip, then this is it.
Click here to check out Treat Your Own Hip, and indeed Treat Your Own Hip!
PS: if you have musculoskeletal problems elsewhere in your body, you might want to check out the rest of his body parts series (neck, back, shoulder, wrist, knee, ankle) for the one that’s tailored to your specific problem.
