Ashwagandha: The Root Of All Even-Mindedness?
In the past few years, Ashwagandha root has been enjoying popular use in consumer products ranging from specialist nootropic supplement stacks, to supermarket teas and hot chocolates.
This herb is considered to have a calming effect, but the science goes a lot deeper than that. Let’s take a look!
Last summer, a systematic review was conducted, that asked the question:
Does Ashwagandha supplementation have a beneficial effect on the management of anxiety and stress?
While they broadly found the answer was “yes”, they expressed low confidence, and even went so far as to say there was contradictory evidence. We (10almonds) were not able to find any contradictory evidence, and their own full article had been made inaccessible to the public, so we couldn’t double-check theirs.
We promptly did our own research review, and we found many studies this year supporting Ashwaghanda’s use for the management of anxiety and stress, amongst other benefits.
First, know: Ashwagandha’s scientific name is “Withania somnifera”, so if you see that (or a derivative of it) mentioned in a paper or extract, it’s the same thing.
Onto the benefits…
A study from the same summer investigated “the efficacy of Withania somnifera supplementation on adults’ cognition and mood”, and declared that:
“in conclusion, Ashwagandha supplementation may improve the physiological, cognitive, and psychological effects of stress.”
We notice the legalistic “may improve”, but the data itself seems more compelling than that, because the study showed that it in fact “did improve” those things. Specifically, Ashwagandha out-performed placebo in most things they measured, and most (statistically) significantly, reduced cortisol output measurably. Cortisol, for any unfamiliar, is “the stress hormone”.
Another study that looked into its anti-stress properties is this one:
Ashwagandha Modulates Stress, Sleep Dynamics, and Mental Clarity
This study showed that Ashwagandha significantly outperformed placebo in many ways, including:
- sleep quality
- cognitive function
- energy, and
- perceptions of stress management.
Ashwagandha is popular among students, because it alleviates stress while also promising benefits to memory, attention, and thinking. So, this study on students caught our eye:
Their findings demonstrated that Ashwagandha increased college students’ perceived well-being through supporting sustained energy, heightened mental clarity, and enhanced sleep quality.
That was about perceived well-being and based on self-reports, though
So: what about hard science?
A later study (in September) found supplementation with 400 mg of Ashwagandha improved executive function, helped sustain attention, and increased short-term/working memory.
Read the study: Effects of Acute Ashwagandha Ingestion on Cognitive Function
❝But aside from the benefits regarding stress, anxiety, sleep quality, cognitive function, energy levels, attention, executive function, and memory, what has Ashwagandha ever done for us?❞
Well, there have been studies investigating its worth against depression, like this one:
Can Traditional Treatment Such as Ashwagandha Be Beneficial in Treating Depression?
Their broad answer: Ashwagandha works against depression, but they don’t know how it works.
They did add: “Studies also show that ashwagandha may bolster the immune system, increase stamina, fight inflammation and infection, combat tumors*, reduce stress, revive the libido, protect the liver and soothe jangled nerves.
That’s quite a lot, including a lot of physical benefits we’ve not explored in this research review which was more about Ashwagandha’s use as a nootropic!
We’ve been focusing on the more mainstream, well-studied benefits, but for any interested in Ashwagandha’s anti-cancer potential, here’s an example:
Evaluating anticancer properties of [Ashwagandha Extract]-a potent phytochemical
In summary:
There is a huge weight of evidence (of which we’ve barely skimmed the surface here in this newsletter, but there’s only so much we can include, so we try to whittle it down to the highest quality most recent most relevant research) to indicate that Ashwagandha is effective…
- Against stress
- Against anxiety
- Against depression
- For sleep quality
- For memory (working, short-term, and long-term)
- For mental clarity
- For attention
- For stamina
- For energy levels
- For libido
- For immune response
- Against inflammation
- Against cancer
- And more*
*(seriously, this is not hyperbole… We didn’t even look at its liver-protective functions, for instance)
Bottom line:
You’d probably like some Ashwagandha now, right? We know we would.
We don’t sell it (or anything else, for that matter), but happily the Internet does:

The Beautiful Cure – by Dr. Daniel Davis
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 one is not just a book about the history of immunology and a primer on how the immune system works. It is those things too, but it’s more:
Dr. Daniel Davis, a professor of immunology and celebrated researcher in his own right, bids us look at not just what we can do, but also what else we might.
This is not to say that the book is speculative; Dr. Davis deals in data rather than imaginings. He also cautions us against falling prey to sensationalization of the “beautiful cures” that the field of immunology is working towards. What, then, are these “beautiful cures”?
Just like our immune systems (in the plural; by Dr. Davis’ count, primarily talking about our innate and adaptive immune systems) can in principle deal with any biological threat, but in practice don’t always get it right, the same goes for our medicine.
He argues that in principle, we categorically can cure any immune-related disease (including autoimmune diseases, and tangentially, cancer). The theoretical existence of such cures is a mathematically known truth. The practical, contingent existence of them? That’s what takes the actual work.
The style of the book is accessible pop science, with a hard science backbone from start to finish.
Bottom line: if you’d like to know more about immunology, and be inspired with hope and wonder without getting carried away, this is the book for you.

Quinoa vs Couscous – 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 quinoa to couscous, we picked the quinoa.
Why?
Firstly, quinoa is the least processed by far. Couscous, even if wholewheat, has by necessity been processed to make what is more or less the same general “stuff” as pasta. Now, the degree to which something has or has not been processed is a common indicator of healthiness, but not necessarily declarative. There are some processed foods that are healthy (e.g. many fermented products) and there are some unprocessed plant or animal products that can kill you (e.g. red meat’s health risks, or the wrong mushrooms). But in this case—quinoa vs couscous—it’s all borne out pretty much as expected.
For the purposes of the following comparisons, we’ll be looking at uncooked/dry weights.
In terms of macros, quinoa has a little more protein, slightly lower carbs, and several times the fiber. The amino acids making up quinoa’s protein are also much more varied.
In the category of vitamins, quinoa has more of vitamins A, B1, B2, B6, and B9, while couscous boasts a little more of vitamins B3 and B5. Given the respective margins of difference, as well as the total vitamins contained, this category is an easy win for quinoa.
When it comes to minerals, this one’s not even more clear. Quinoa has a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. Couscous, meanwhile has more of just one mineral: sodium. So, maybe not one you want more of.
All in all, today’s is an easy pick: quinoa!

Common Hospital Blood Pressure Mistake (Don’t Let This Happen To You Or A Loved One)
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.
There’s a major issue in healthcare, Dr. Suneel Dhand tells us, pertaining to the overtreatment of hypertension in hospitals. Here’s how to watch out for it and know when to question it:
Under pressure
When patients, particularly from older generations, are admitted to the hospital, their blood pressure often fluctuates due to illness, dehydration, and other factors. Despite this, they are often continued on their usual blood pressure medications, which can lead to dangerously low blood pressure.
Why does this happen? The problem arises from rigid protocols that dictate stopping blood pressure medication only if systolic pressure is below a certain threshold, often 100. However, Dr. Dhand argues that 100 is already low*, and administering medication when blood pressure is close to this can cause it to drop dangerously lower
*10almonds note: low for an adult, anyway, and especially for an older adult. To be clear: it’s not a bad thing! That is the average systolic blood pressure of a healthy teenager and it’s usually the opposite of a problem if we have that when older (indeed, this very healthy writer’s blood pressure averages 100/70, and suffice it to say, it’s been a long time since I was a teenager). But it does mean that we definitely don’t want to take medications to artificially lower it from there.
Low blood pressure from overtreatment can lead to severe consequences, requiring emergency interventions to stabilize the patient.
Dr. Dhand’s advice for patients and families is:
- Ensure medication accuracy: make sure the medical team knows the correct blood pressure medications and dosages for you or your loved one.
- Monitor vital signs: actively check blood pressure readings, especially if they are in the low 100s or even 110s, and discuss any medication concerns with the medical team.
- Watch for symptoms of low blood pressure: be alert for symptoms like dizziness or weakness, which could indicate dangerously low blood pressure.

Chicken or Fish – 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 chicken to fish, we picked the fish.
Why?
To understand the choice, we have to start a bit earlier on the decision tree. For most people most of the time, when it comes to a diet high in plants or high in animals, the plant-centric diet will generally be best:
Do We Need Animal Products To Be Healthy?
When it comes to animal meats, red meat is a fairly uncontroversial first thing to strike off the list:
…with pork and some other meats not being much better.
But chicken? Poultry in general appears to be quite health-neutral. The jury is out and the science has mixed results, but the data is leaning towards “it’s probably fine”.
See for example this huge (n=29,682) study:
this same paper shows that…
❝higher intake of processed meat, unprocessed red meat, or poultry, but not fish, was significantly associated with a small increased risk of incident CVD, whereas higher intake of processed meat or unprocessed red meat, but not poultry or fish, was significantly associated with a small increased risk of all-cause mortality❞
So, since poultry isn’t significantly increasing all-cause mortality, and fish isn’t significantly increasing all-cause mortality or cardiovascular disease, fish comes out as the hands-down (fins-down?) winner.
One more (this time, easy) choice to make, though!
While fish in general (please, not fried, though!) is generally considered quite healthy, there is a big difference (more than you might think, and for reasons that are quite alarming), between…

Sweet Potato & Black Bean 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.
Fiber, protein, and polyphenols! What more could one ask for? Well, great taste and warm healthy goodness, which these deliver:
You will need
For the sweet potatoes:
- 2 medium sweet potatoes, cubed (we recommend leaving the skin on, but you can peel them if you really want to)
- 1 tbsp extra virgin olive oil
- 2 tsp garlic powder
- 2 tsp smoked paprika
- 1 tsp chili powder
- 1 tsp black pepper
- 1 tsp ground cumin
- 1 tsp ground turmeric
- ½ tsp MSG or 1 tsp low-sodium salt
For the black beans:
- 2 cans black beans, drained and rinsed (or 2 cups black beans that you cooked yourself)
- ¼ bulb garlic, minced
- 1 fresh jalapeño finely chopped (or ¼ cup jalapeños from a jar, finely chopped) ← adjust quantities per your preference and per the quality of the pepper(s) you’re using; we can’t judge that from here without tasting them, so we give a good basic starting suggestion.
- 2 tsp black pepper
- 1 tsp red chili flakes
- ½ tsp MSG or 1 tsp low-sodium salt
For serving:
- 8 small corn tortillas, or your preference if substituting
- 1 avocado, pitted, peeled, cubed, and tossed in lime juice ← we’re mentioning this here because you want to do this as soon as you cut it, to avoid oxidation
- Any other salad you’d like to include; fresh parsley is also a good option when it comes to greenery, or cilantro if you don’t have the soap gene
- Tomato salsa (quantity and spice level per your preference)
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 400°F / 200°C.
2) Toss the sweet potato cubes in a large bowl with the rest of the ingredients from the sweet potato section above, ensuring they are evenly coated.
3) Bake them in the oven, on a baking tray lined with baking paper, for about 30 minutes or until tender inside and crispy at the edges. Turn them over halfway through.
4) While that’s happening, mix the black beans in a bowl with the other ingredients from the black bean section above, and heat them gently. You could do this in a saucepan, but honestly, while it’s not glamorous, the microwave is actually better for this. Note: many people find the microwave cooks food unevenly, but there are two reasons for this and they’re both easily fixable:
- instead of using high power for x minutes, use medium power for 2x minutes; this will produce better results
- instead of putting the food just in a bowl, jug, or similar, use a wide bowl or similar container, and then inside that, place a small empty microwave-safe glass jar or similar upturned in the middle, and then add the food around it, so that the food is arranged in a donut shape rather than a wide cylinder shape. This means there is no “middle bit” to go underheated while the edges are heated excessively; instead, it will heat through evenly.
If you really don’t want to do that though, use a saucepan on a very low heat, add a small amount of liquid (or tomato salsa), and stir constantly.
5) Heat the tortillas in a dry skillet for about 30 seconds each on each side, when ready to serve.
6) Assemble the tacos; you can do this how you like but a good order of operations is: tortilla, leafy salad (if using), potato, beans, non-leafy salad including avocado, salsa or other topping per your preference.
Enjoy!
