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:

The Bare-Bones Truth About Osteoporosis
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 issue of 10almonds, we asked you “at what age do you think it’s important to start worrying about osteoporosis?”, and here’s the spread of answers you gave us:
The Bare-bones Truth About Osteoporosis
In yesterday’s issue of 10almonds, we asked you “at what age do you think it’s important to start worrying about osteoporosis?”, and here’s the spread of answers you gave us:
At first glance it may seem shocking that a majority of respondents to a poll in a health-focused newsletter think it’ll never be an issue worth worrying about, but in fact this is partly a statistical quirk, because the vote of the strongest “early prevention” crowd was divided between “as a child” and “as a young adult”.
This poll also gave you the option to add a comment with your vote. Many subscribers chose to do so, explaining your choices… But, interestingly, not one single person who voted for “never” had any additional thoughts to add.
We loved reading your replies, by the way, and wish we had room to include them here, because they were very interesting and thought-provoking.
Let’s get to the myths and facts:
Top myth: “you will never need to worry about it; drink a glass of milk and you’ll be fine!”
The body is constantly repairing itself. Its ability to do that declines with age. Until about 35 on average, we can replace bone mineral as quickly as it is lost. After that, we lose it by up to 1% per year, and that rate climbs after 50, and climbs even more steeply for those who go through (untreated) menopause.
Losing 1% per year might not seem like a lot, but if you want to live to 100, there are some unfortunate implications!
About that menopause, by the way… Because declining estrogen levels late in life contribute significantly to osteoporosis, hormone replacement therapy (HRT) may be of value to many for the sake of bone health, never mind the more obvious and commonly-sought benefits.
On the topic of that glass of milk…
- Milk is a great source of calcium, which is useless to the body if you don’t also have good levels of vitamin D and magnesium.
- People’s vitamin D levels tend to directly correlate to the level of sun where they live, if supplementation isn’t undertaken.
- Plant-based milks are usually fortified with vitamin D (and calcium), by the way.
- Most people are deficient in magnesium, because green leafy things don’t form as big a part of most people’s diets as they should.

Next most common myth: “bone health is all about calcium”
We spoke a little above about the importance of vitamin D and magnesium for being able to properly use that. But potassium is also critical:

While we’re on the topic…
People think of collagen as being for skin health. And it is important for that, but collagen’s benefits (and the negative effects of its absence) go much deeper, to include bone health. We’ve written about this before, so rather than take more space today, we’ll just drop the link:

Black Bean Hummus Panini
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.
A recipe for a sandwich? Try it once, and you’ll see why. Welcome to your new favorite!
You will need
- 1 cup cooked-and-rinsed black beans (canned is fine)
- ⅓ cup hummus (you can use our Hero Homemade Hummus recipe)
- 4 thin slices of eggplant (or more if you like it meaty)
- 4 sun-dried tomatoes
- 2 slices of your favorite bread (you can use our Delicious Quinoa Avocado Bread recipe)
- A little olive oil, ideally sprayable
Method
(we suggest you read everything at least once before doing anything)
1) Grill the eggplant slices until soft.
2) Spread hummus generously on one side of both slices of bread.
2) Add the black beans on top of one slice (the hummus will help them stay in place), followed by the sun-dried tomatoes and then the eggplant. Top with the other slice of bread, hummus-side down.
3) Coat (carefully, please) the inside of the panini press (both interior sides) with olive oil. If you don’t have sprayable oil, using a sheet of kitchen roll to apply the oil is a good way to do it without making a mess.
4) Grill the assembled sandwich, until the bread starts to brown and the insides are warm; this should take about 4 minutes.
Enjoy!

How To Recover Quickly From A Stomach Bug
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 To Recover Quickly From A Stomach Bug
Is it norovirus, or did you just eat something questionable? We’re not doctors, let alone your doctors, and certainly will not try to diagnose from afar. And as ever, if unsure and/or symptoms don’t go away or do get worse, seek professional medical advice.
That out of the way, we can give some very good general-purpose tips for this one…
Help your immune system to help you
So far as you can, you want a happy healthy immune system. For the most part, we’d recommend the following things:
Beyond Supplements: The Real Immune-Boosters!
…but you probably don’t want to be exercising with a stomach bug, so perhaps sit that one out. Exercise is the preventative; what you need right now is rest.
Hydrate—but watch out
Hydration is critical for recovery especially if you have diarrhea, but drinking too much water too quickly will just make things worse. Great options for getting good hydration more slowly are:
- Peppermint tea
- (peppermint also has digestion-settling properties)
- Ginger tea
- See also: Ginger Does A Lot More Than You Think
- Broths
- These will also help replenish your sodium and other nutrients, gently. Chicken soup for your stomach, and all that. A great plant-based option is sweetcorn soup.
- By broths, we mean clear(ish) water-based soups. This is definitely not the time for creamier soups.
❝Milk and dairy products should be avoided for 24 to 48 hours as they can make diarrhea worse.
Initial dietary choices when refeeding should begin with soups and broth.❞
Source: American College of Gastroenterology
Other things to avoid
Caffeine stimulates the digestion in a way that can make things worse.
Fat is more difficult to digest, and should also be avoided until feeling better.
To medicate or not to medicate?
Loperamide (also known by the brand name Imodium) is generally safe when used as directed.
Click here to see its uses, dosage, side effects, and contraindications
Antibiotics may be necessary for certain microbial infections, but should not be anyone’s first-choice treatment unless advised otherwise by your doctor/pharmacist.
Note that if your stomach bug is not something that requires antibiotics, then taking antibiotics can actually make it worse as the antibiotics wipe out your gut bacteria that were busy helping fight whatever’s going wrong in there:
- Facing a new challenge: the adverse effects of antibiotics on gut microbiota and host immunity
- Antibiotics as major disruptors of gut microbiota
- Microbiotoxicity: antibiotic usage and its unintended harm to the microbiome
A gentler helper
If you want to give your “good bacteria” a hand while giving pathogens a harder time of it, then a much safer home remedy is a little (seriously, do not over do it; we are talking 1–2 tablespoons, or around 20ml) apple cider vinegar, taken diluted in a glass of water.
❝Several studies indicate apple cider vinegar (ACV)’s usefulness in lowering postprandial glycemic response, specifically by slowing of gastric motility❞
(Slowing gastric motility is usually exactly what you want in the case of a stomach bug, and apple cider vinegar)

Less Common Oral Hygiene Options
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.
Less Common Alternatives For Oral Hygiene!
You almost certainly brush your teeth. You might use mouthwash. A lot of people floss for three weeks at a time, often in January.
There are a lot of options for oral hygiene; variations of the above, and many alternatives too. This is a big topic, so rather than try to squeeze it all in one, this will be a several-part series.
- The first part was: Toothpastes & Mouthwashes: Which Help And Which Harm?
- The second part was: Flossing, Better (And Easier!)
- The third (and for now at least, final) part will look at some less common alternatives.
Tooth soap
The idea here is simplicity, and brushing with as few ingredients as possible. Soap cleans your teeth the same way it cleans your (sometimes compositionally quite similar—enamel and all) dishes, without damaging them.
We’d love to link to some science here, but alas, it appears to have not yet been done—at least, we couldn’t find any!
You can make your own tooth soap if you are feeling confident, or you might prefer to buy one ready-made (here’s an example product on Amazon, with various flavor options)
Oil pulling
We are getting gradually more scientific now; there is science for this one… But the (scientific) reviews are mixed:
Wooley et al., 2020, conducted a review of extant studies, and concluded:
❝The limited evidence suggests that oil pulling with coconut oil may have a beneficial effect on improving oral health and dental hygiene❞
The “Science-Based Medicine” project was less positive in its assessment, and declared that all and any studies that found oil pulling to be effective were a matter of researcher/publication bias. We would note that SBM is a private project and is not without its own biases, but for balance, here is what they had to offer:
A more rounded view seems to be that it is a good method for cleaning your teeth if you don’t have better options available (whereby, “better options” is “almost any other method”).
One final consideration, which the above seemed not to consider, is:
If you have sensitive teeth/gums, oil-pulling is the gentlest way of cleaning them, and getting them back into sufficient order that you can comfortably use other methods.
Want to try it? You can use any food-grade oil (coconut oil or olive oil are common choices).
Chewing stick
Not just any stick—a twig of the Salvadora persica tree. This time, there’s lots of science for it, and it’s uncontroversially effective:
❝A number of scientific studies have demonstrated that the miswak (Salvadora persica) possesses antibacterial, anti-fungal, anti-viral, anti-cariogenic, and anti-plaque properties.
Several studies have also claimed that miswak has anti-oxidant, analgesic, and anti-inflammatory effects. The use of a miswak has an immediate effect on the composition of saliva.
Several clinical studies have confirmed that the mechanical and chemical cleansing efficacy of miswak chewing sticks are equal and at times greater than that of the toothbrush❞
Read in full: A review of the therapeutic effects of using miswak (Salvadora Persica) on oral health
And about the efficacy vs using a toothbrush, here’s an example:
Comparative effect of chewing sticks and toothbrushing on plaque removal and gingival health
Want to try the miswak stick? Here’s an example product on Amazon.

Unbroken – by Dr. MaryCatherine McDonald
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 reviewed books about trauma before, so what makes this one different? Mostly, it’s the different framing.
Dr. McDonald advocates for a neurobiological understanding of trauma, which really levels the playing field when it comes to different types of trauma that are often treated very differently, when the end result in the brain is more or less the same.
Does this mean she proposes a “one-size fits all” approach? Kind of!
Insofar as she offers a one-size fits all approach that is then personalized by the user, but most of her advices will go for most kinds of trauma in any case. This is particularly useful for any of us who’ve ever hit a wall with therapists when they expect a person to only be carrying one major trauma.
Instead, with Dr. McDonald’s approach, we can take her methods and use them for each one.
After an introduction and overview, each chapter contains a different set of relevant psychological science explored through a case study, and then at the end of the chapter, tools to use and try out.
The style is very light and readable, notwithstanding the weighty subject matter.
Bottom line: if you’ve been trying to deal with (or avoid dealing with) some kind(s) of trauma, this book will doubtlessly contain at least a few new tools for you. It did for this reviewer, who reads a lot!

Spark – by Dr. John Ratey
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 all know that exercise is good for mental health as well as physical. So, what’s so revolutionary about this “revolutionary new science of exercise and the brain”?
A lot of it has to do with the specific neuroscience of how exercise has not only a mood-boosting effect (endorphins) and neuroprotective effect (helping to guard against cognitive decline), but also promotes neuroplasticity… e.g., the creation and strengthening of neural pathways, as well as boosting the structure of the brain in some parts such as the cerebellum.
The book also covers not just “exercise has these benefits”, but also the “how this works” of all kinds of brain benefits, including:
- against Alzheimer’s
- mitigating ADHD
- managing menopause
- dealing with addiction
…and more. And once we understand how something works, we’re far more likely to be motivated to actually do the kinds of exercises that give the specific benefits we want/need. Which is very much the important part!
In short: this book will tell you what you need to know to get you doing the exercises you need to enjoy those benefits—very much worth it!
