Ayurveda’s Contributions To Science (Without Being Itself Rooted in Scientific Method)
Yesterday, we asked you for your opinions on ayurveda, and got the above-depicted, below-described, set of responses. Of those who responded…
- A little over 41% said “I don’t know what ayurveda is without looking it up”
- A little over 37% said “It is a fine branch of health science with millennia of evidence”
- A little over 16% said “It gets some things right, but not by actual science”
- A little over 4% said “It is a potentially dangerous pseudoscience”
So, what does the science say?
Ayurveda is scientific: True or False?
False, simply. Let’s just rip the band-aid off in this case. That doesn’t mean it’s necessarily without merit, though!
Let’s put it this way:
- If you drink coffee to feel more awake because scientific method has discerned that caffeine has vasoconstrictive and adenosine-blocking effects while also promoting dopaminergic activity, then your consumption of coffee is evidence-based and scientific. Great!
- If you drink coffee to feel more awake because somebody told you that that somebody told them that it energizes you by balancing the elements fire (the heat of the coffee), air (the little bubbles on top), earth (the coffee grinds), water (the water), and ether (steam), then that is neither evidence-based nor scientific, but it will still work exactly the same.
Ayurveda is a little like that. It’s an ancient traditional Indian medicine, based on a combination of anecdotal evidence and supposition.
- The anecdotal evidence from ayurveda has often resulted in herbal remedies that, in modern scientific trials, have been found to have merit.
- Ayurvedic meditative practices also have a large overlap with modern mindfulness practices, and have also been found to have merit
- Ayurveda also promotes the practice of yoga, which is indeed a very healthful activity
- The supposition from ayurveda is based largely in those five elements we mentioned above, as well as a “balancing of humors” comparable to medieval European medicine, and from a scientific perspective, is simply a hypothesis with no evidence to support it.
Note: while ayurveda is commonly described as a science by its practitioners in the modern age, it did not originally claim to be scientific, but rather, wisdom handed down directly by the god Dhanvantari.
Ayurveda gets some things right: True or False?
True! Indeed, we covered some before in 10almonds; you may remember:
Bacopa Monnieri: A Well-Evidenced Cognitive Enhancer
(Bacopa monnieri is also known by its name in ayurveda, brahmi)
There are many other herbs that have made their way from ayurveda into modern science, but the above is a stand-out example. Others include:
- Ashwagandha: The Root of All Even-Mindedness?
- Boswellia serrata (Frankincense) Against Pain and Depression/Anxiety
Yoga and meditation are also great, and not only that, but great by science, for example:
- NCCIH | Yoga for Health: Clinical Guidelines, Scientific Literature, Info for Patients
- The Neuroscience of Mindfulness: How Mindfulness Alters the Brain and Facilitates Emotion Regulation
Ayurveda is a potentially dangerous pseudoscience: True or False?
Also True! We covered why it’s a pseudoscience above, but that doesn’t make it potentially dangerous, per se (you’ll remember our coffee example).
What does, however, make it potentially dangerous (dose-dependent) is its use of heavy metals such as lead, mercury, and arsenic:

Some final thoughts…
Want to learn more about the sometimes beneficial, sometimes uneasy relationship between ayurveda and modern science?
A lot of scholarly articles trying to bridge (or further separate) the two were very biased one way or the other.
Instead, here’s one that’s reasonably optimistic with regard to ayurveda’s potential for good, while being realistic about how it currently stands:

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!

The Daily Stoic – by Ryan Holiday & Stephen Hanselman
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’s this, a philosophy book in a health and productivity newsletter? Well, look at it this way: Aristotle basically wrote the “How To Win Friends And Influence People” of his day, and Plato before him wrote a book about management.
In this (chiefly modern!) book, we see what the later Stoic philosophers had to say about getting the most out of life—which is also what we’re about, here at 10almonds!
We tend to use the word “stoic” in modern English to refer to a person who is resolute in the face of hardship. The traditional meaning does encompass that, but also means a lot more: a whole, rounded, philosophy of life.
Philosophy in general is not an easy thing into which to “dip one’s toe”. No matter where we try to start, it seems, it turns out there were a thousand other things we needed to read first!
This book really gets around that. The format is:
- There’s a theme for each month
- Each month has one lesson per day
- Each daily lesson starts with some words from a renowned stoic philosopher, and then provides commentary on such
- The commentary provides a jumping-off point and serves as a prompt to actually, genuinely, reflect and apply the ideas.
Unlike a lot of “a year of…” day-by-day books, this is not light reading, by the way, and you are getting a weighty tome for your money.
But, the page-length daily lessons are indeed digestible—which, again, is what we like at 10almonds!

Xylitol vs Erythritol – 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 xylitol to erythritol, we picked the xylitol.
Why?
They’re both sugar alcohols, which so far as the body is concerned are neither sugars nor alcohols in the way those words are commonly understood; it’s just a chemical term. The sugars aren’t processed as such by the body and are passed as dietary fiber, and nor is there any intoxicating effect as one might expect from an alcohol.
In terms of macronutrients, while technically they both have carbs, for all functional purposes they don’t and just have a little fiber.
In terms of micronutrients, they don’t have any.
The one thing that sets them apart is their respective safety profiles. Xylitol is prothrombotic and associated with major adverse cardiac events (CI=95, adjusted hazard ratio=1.57, range=1.12-2.21), while erythritol is also prothrombotic and more strongly associated with major adverse cardiac events (CI=95, adjusted hazard ratio=2.21, range=1.20-4.07).
So, xylitol is bad and erythritol is worse, which means the relatively “healthier” is xylitol. We don’t recommend either, though.
Studies for both:
- Xylitol is prothrombotic and associated with cardiovascular risk
- The artificial sweetener erythritol and cardiovascular event risk

- The Fascinating Truth About Aspartame, Cancer, & Neurotoxicity ← under the cold light of science, aspartame isn’t actually as bad as it was painted a few decades ago, mostly by a viral hoax letter. Per the WHO’s advice, it’s still good to avoid sweeteners in general, however.
Take care!

One Cause; Countless Aches
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 Is The Cause?
Zac Cupples’ video (below) makes an appealing claim: 90% of movement issues and discomforts we experience daily come from one source: reduced joint space due to increased muscle tension.
For Cupples, this could be causing anything from knee pain to foot pain to ankle pain to hip pain to generalized joint pain to…pretty much any sort of pain.
So, why do we describe this as “appealing”?
Well, if there’s just one cause, that means there is only one thing to fix
Can This Be True?
Whilst we normally stray away from oversimplifications, we found Cupples’ example quite powerful.
Cupples defends his thesis by illustrating it with a simple wrist movement experiment: try moving your wrist in a circle with your palm open, and then do the same with your fist clenched.
Did you notice a difference?
When you clench your fist, movement (normally) becomes restricted and uncomfortable, illustrating how increased tension limits joint space.
It’s a powerful analogy for understanding our body’s mechanics.
So How Do We Fix It?
To combat issues with reduced joint space, Cupples proposes a three-step solution: reducing muscle tension, increasing range of motion in commonly limited areas, and enhancing movement efficiency. He delves into strategies for achieving these, including adopting certain positions and breathing techniques.
There are also some elements of strategic muscle engagement, but we’ll leave that to him to describe:

Why Some People Get Sick More (And How To Not Be One Of Them)
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.
Some people have never yet had COVID (so far so good, this writer included); others are on their third bout already; others have not been so lucky and are no longer with us to share their stories.
Obviously, even the healthiest and/or most careful person can get sick, and it would be folly to be complacent and think “I’m not a person who gets sick; that happens to other people”.
Nor is COVID the only thing out there to worry about; there’s always the latest outbreak-du-jour of something, and there are always the perennials such as cold and flu—which are also not to be underestimated, because both weaken us to other things, and flu has killed very many, from the 50,000,000+ in the 1918 pandemic, to the 700,000ish that it kills each year nowadays.
And then there are the combination viruses:
Move over, COVID and Flu! We Have “Hybrid Viruses” To Contend With Now
So, why are some people more susceptible?
Firstly, some people are simply immunocompromised. This means for example that:
- perhaps they have an inflammatory/autoimmune disease of some kind (e.g. lupus, rheumatoid arthritis, type 1 diabetes), or…
- perhaps they are taking immunosuppressants for some reason (e.g. because they had an organ transplant), or…
- perhaps they have a primary infection that leaves them vulnerable to secondary infections. Most infections will do this to some degree or another, but some are worse for it than others; untreated HIV is a clear example. The HIV itself may not kill people, but (if untreated) the resultant AIDS will leave a person open to being killed by almost any passing opportunistic pathogen. Pneumonia of various kinds being high on the list, but it could even be something as simple as the common cold, without a working immune system to fight it.
See also: How To Prevent (Or Reduce) Inflammation
And for that matter, since pneumonia is a very common last-nail-in-the-coffin secondary infection (especially: older people going into hospital with one thing, getting a secondary infection and ultimately dying as a result), it’s particularly important to avoid that, so…
See also: Pneumonia: What We Can & Can’t Do About It
Secondly, some people are not immunocompromised per the usual definition of the word, but their immune system is, arguably, compromised.
Cortisol, the stress hormone, is an immunosuppressant. We need cortisol to live, but we only need it in small bursts here and there (such as when we are waking up the morning). When high cortisol levels become chronic, so too does cortisol’s immunosuppressant effect.
Top things that cause elevated cortisol levels include:
- Stress
- Alcohol
- Smoking
Thus, the keys here are to 1) not smoke 2) not drink, ideally, or at least keep consumption low, but honestly even one drink will elevate cortisol levels, so it’s better not to, and 3) manage stress.
See also: Lower Your Cortisol! (Here’s Why & How)
Other modifiable factors
Being aware of infection risk and taking steps to reduce it (e.g. avoiding being with many people in confined indoor places, masking as appropriate, handwashing frequently) is a good preventative strategy, along with of course getting any recommended vaccines as they come available.
What if they fail? How can we boost the immune system?
We talked about not sabotaging the immune system, but what about actively boosting it? The answer is yes, we certainly can (barring serious medical reasons why not), as there are some very important lifestyle factors too:
Beyond Supplements: The Real Immune-Boosters!
One final last-line thing…
Since if we do get an infection, it’s better to know sooner rather than later… A recent study shows that wearable activity trackers can (if we pay attention to the right things) help predict disease, including highlighting COVID status (positive or negative) about as accurately (88% accuracy) as rapid screening tests. Here’s a pop-science article about it:
Wearable activity trackers show promise in detecting early signals of disease

Death by Sitting – by Carolyne Thompson
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.
You may be wondering: is this a lot of words to say “sit down less”?
And the answer is: there’s a lot more in here than that. Of course, yes, “sit down less” is an important take-away, but there’s a lot about the specific problems caused by sitting in chairs, the health risks are that are increased and how, and the early warning signs to watch out for.
After these chapters of woe, most of the book is given over to solutions; about taking standing and walking breaks, tying movement to productivity, why exercise alone is not enough to offset the damage of sitting, relearning ergonomic posture in the context of mitigating the harm, psychological shifts to break the habit of sitting, redefining social norms around sitting and socializing, rewiring one’s body and retraining better movements as well as postures to always immediately move out of if one finds oneself in, and much much more.
The style is light and easy to read, while still including scientific research as appropriate along with practical, actionable advice.
Bottom line: if you’d like to do better for your body than slowly killing it for however many hours a day, then this book has a wealth of advice far beyond the obvious (but important!) “sit less”.
