Our Verdict
When comparing sweet potato to winter squash, we picked the sweet potato.
Why?
In terms of macros, the sweet potato has 2x the protein, 2x the carbs, and slightly more fiber. Because the protein numbers are small, the carb:fiber ratio is the deciding factor here, and has winter squash has the lower glycemic index (assuming cooking them both on a like-for-like basis), we’re going with that on macros, but it’s subjective.
In the category of vitamins, sweet potato has more of vitamins A, B1, B2, B3, B5, B6, C, E, and choline, while winter squash has more of vitamins B9 and K. It’s interesting to note that while sweet potato is rightly famous for its vitamin A content, winter squash is actually very good for that too. Still, by the numbers, it’s a clear 9:2 victory for sweet potato here.
When it comes to minerals, sweet potato has more calcium copper, iron, magnesium, manganese, phosphorus, potassium, and zinc, while winter squash has more selenium, meaning an 8:1 victory for sweet potato this time.
In short, enjoy either or both, but sweet potato is the more nutritionally dense option for sure.

Tribulus Terrestris For Testosterone?
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.
(Clinical) Trials and Tribul-ations
In the category of supplements that have enjoyed use as aphrodisiacs, Tribulus terrestris (also called caltrop, goat’s head, gokshura, or puncture vine) has a long history, having seen wide use in both Traditional Chinese Medicine and in Ayurveda.
It’s been used for other purposes too, and has been considered a “general wellness” plant.
So, what does the science say?
Good news: very conclusive evidence!
Bad news: the conclusion is not favorable…
Scientists are known for their careful use of clinical language, and it’s very rare for a study/review to claim something as proven (scientists leave journalists to do that part), and in this case, when it comes to Tribulus’s usefulness as a testosterone-enhancing libido-boosting supplement…
❝analysis of empirical evidence from a comprehensive review of available literature proved this hypothesis wrong❞
Strong words! You can read it in full here; they do make some concessions along the way (e.g. mentioning unclear or contradictory findings, suggesting that it may have some effect, but by an as-yet unknown mechanism if it does—although some potential effect on nitric oxide levels has been hypothesized, which is reasonable if so, as NO does feature in arousal-signalling), but the general conclusion is “no, this doesn’t have androgen-enhancing properties”:
Pro-sexual and androgen enhancing effects of Tribulus terrestris L.: Fact or Fiction
That’s a review though, what about taking a look at a representative RCT? Here we go:
❝Tribulus terrestris was not more effective than placebo on improving symptoms of erectile dysfunction or serum total testosterone❞
As a performance-enhancer in sport
We’ll be brief here: it doesn’t seem to work and it may not be safe:
Insights into Supplements with Tribulus Terrestris used by Athletes
From sport, into general wellness?
Finally, a study that finds it may be useful for something!
❝Overall, participants supplemented with TT displayed significant improvements in lipid profile. Inflammatory and hematological biomarkers showed moderate beneficial effects with no significant changes on renal biomarkers. No positive effects were observed on the immune system response. Additionally, no TT-induced toxicity was reported.
In conclusion, there was no clear evidence of the beneficial effects of TT supplementation on muscle damage markers and hormonal behavior.❞
About those lipids…
Animal studies have shown that it may not only improve lipid profiles, but also may partially repair the endothelial dysfunction resulting from hyperlipidemia:
Want to try some?
In the unlikely event that today’s research review has inspired you with an urge to try Tribulus terrestris, here’s an example product on Amazon
If on the other hand you’d like to actually increase testosterone levels, then we suggest:

Algorithms to Live By – by Brian Christian and Tom Griffiths

As humans, we subconsciously use heuristics a lot to make many complex decisions based on “fuzzy logic”. For example:
Do we buy the cheap shoes that may last us a season, or the much more expensive ones that will last us for years? We’ll—without necessarily giving it much conscious thought—quickly weigh up:
- How much do we like each prospective pair of shoes?
- What else might we need to spend money on now/soon?
- How much money do we have right now?
- How much money do we expect to have in the future?
- Considering our lifestyle, how important is it to have good quality shoes?
How well we perform this rapid calculation may vary wildly, depending on many factors ranging from the quality of the advertising to how long ago we last ate.
And if we make the wrong decision, later we may have buyer’s (or non-buyer’s!) remorse. So, how can we do better?
Authors Brain Christian and Tom Griffiths have a manual for us!
This book covers many “kinds” of decision we often have to make in life, and how to optimize those decisions with the power of mathematics and computer science.
The problems (and solutions) run the gamut of…
- Optimal stopping (when to say “alright, that’s good enough”)
- Overcoming cognitive biases
- Scheduling quandaries
- Bayes’ Theorem
- Game Theory
- And when it’s more efficient to just leave things to chance!
…and many more (12 main areas of decision-making are covered).
For all it draws heavily from mathematics and computer science, the writing style is very easy-reading. It’s a “curl up in the armchair and read for pleasure” book, no matter how weighty and practical its content.
Bottom line: if you improve your ability to make the right decisions even marginally, this book will have been worth your while in the long run!

Fix Chronic Fatigue & Regain Your Energy, By Science
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.
Chronic fatigue is on the rise. A lot of it appears to be Long COVID-related, but whether that’s the case for you or not, one thing that will make a big difference to your energy levels is something that French biochemist Jessie Inchauspé is here to explain:
Mitochondrial management
Inchauspé explains it in terms of a steam train; to keep running, it must have coal burning in its furnace. However, if more coal is delivered to the engine room faster than it can be put in the furnace and burned, and the coal just keeps on coming, the worker there will soon be overwhelmed trying to find places to put it all; the engine room will be full of coal, and the furnace will sputter and go out because the worker can’t even reach it on account of being buried in coal.
So it is with our glucose metabolism also. If we get spikes of glucose faster than our body can deal with them, it will overload the body’s ability to process that energy at all. Just like the steam train worker, our body will try! It’ll stuff that extra glucose wherever it can (storing as glycogen in the liver is a readily available option that’s easy to do and/but also gives you non-alcoholic fatty liver disease and isn’t quickly broken down into useable energy), and meanwhile, your actual mitochondria aren’t getting what they need (which is: a reliable, but gentle, influx of glucose).
You can imagine that the situation we described in the steam train isn’t good for the engine’s longevity, and the corresponding situation in the human body isn’t good for our mitochondria either (or our pancreas, or our liver, or… the list goes on). Indeed, damaged mitochondria affect exercise capacity and stress resilience—as well as being a long-term driver of cancer.
The remedy, of course, is blood sugar management. Specifically, avoiding glucose spikes. She has a list of 10 ways to do this (small changes to how we eat; what things to eat with what, in which order, etc) that make a huge measurable difference. For your convenience, we’ve linked those ten ways below; first though, if you’d like to hear it from Inchauspé directly (her style is very pleasant), enjoy:

Powered by Plants – by Ocean Robbins & Nichole Dandrea-Russert

Of the two authors, the former is a professional public speaker, and the latter is a professional dietician. As a result, we get a book that is polished and well-presented, while actually having a core of good solid science (backed up with plenty of references).
There’s an introductory section that’s all about the “notable nutrients”, that will be focused on in the ingredients choices for the recipes in the rest of the book.
The recipes themselves are simple enough to do quickly, yet interesting enough that you’ll want to do them, and certainly they contain all the plant-based nutrient-density you might expect.
Bottom line: if you’d like to expand your plant-based cooking with a focus on nutrition and ease without sacrificing fun, then this is a great cookbook for that.

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!

In Plain English…
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.
It’s Q&A Time!
This is the bit whereby each week, we respond to subscriber questions/requests/etc
Have something you’d like to ask us, or ask us to look into? Hit reply to any of our emails, or use the feedback widget at the bottom, and a Real Human™ will be glad to read it!
Q: Love to have someone research all the additives in our medicines, (risk of birth control and breast cancer) and what goes in all of our food and beverages. So much info out there, but there are so many variations, you never know who to believe.
That’s a great idea! There are a lot of medicines and food and beverages out there, so that’s quite a broad brief, but! We could well do a breakdown of very common additives, and demystify them, sorting them into good/bad/neutral, e.g:
- Ascorbic acid—Good! This is Vitamin C
- Acetic acid—Neutral! This is vinegar
- Acetylsalicylic acid—Good or Bad! This is aspirin (a painkiller and blood-thinning agent, can be good for you or can cause more problems than it solves, depending on your personal medical situation. If in doubt, check with your doctor)
- Acesulfame K—Generally Neutral! This is a sweetener that the body can’t metabolize, so it’s also not a source of potassium (despite containing potassium) and will generally do nothing. Unless you have an allergy to it, which is rare but is a thing.
- Sucralose—Neutral! This is technically a sugar (as is anything ending in -ose), but the body can’t metabolize it and processes it as a dietary fiber instead. We’d list it as good for that reason, but honestly, we doubt you’re eating enough sucralose to make a noticeable difference to your daily fiber intake.
- Sucrose—Bad! This is just plain sugar
Sometimes words that sound the same can ring alarm bells when they need not, for example there’s a big difference between:
- Potassium iodide (a good source of potassium and iodine)
- Potassium cyanide (the famous poison; 300mg will kill you; half that dose will probably kill you)
- Cyanocobalamine (Vitamin B12)
Let us know if there are particular additives (or particular medications) you’d like us to look at!
While for legal reasons we cannot give medical advice, talking about common contraindications (e.g., it’s generally advised to not take this with that, as one will stop the other from working, etc) is definitely something we could do.
For example! St. John’s Wort, very popular as a herbal mood-brightener, is on the list of contraindications for so many medications, including:
- Antidepressants
- Birth control pills
- Cyclosporine, which prevents the body from rejecting transplanted organs
- Some heart medications, including digoxin and ivabradine
- Some HIV drugs, including indinavir and nevirapine
- Some cancer medications, including irinotecan and imatinib
- Warfarin, an anticoagulant (blood thinner)
- Certain statins, including simvastatin
Q: As I am a retired nurse, I am always interested in new medical technology and new ways of diagnosing. I have recently heard of using the eyes to diagnose Alzheimer’s. When I did some research I didn’t find too much. I am thinking the information may be too new or I wasn’t on the right sites.
(this is in response to last week’s piece on lutein, eyes, and brain health)
We’d readily bet that the diagnostic criteria has to do with recording low levels of lutein in the eye (discernible by a visual examination of macular pigment optical density), and relying on the correlation between this and incidence of Alzheimer’s, but we’ve not seen it as a hard diagnostic tool as yet either—we’ll do some digging and let you know what we find! In the meantime, we note that the Journal of Alzheimer’s Disease (which may be of interest to you, if you’re not already subscribed) is onto this:
See also:
- Journal of Alzheimer’s Disease (mixture of free and paid content)
- Journal of Alzheimer’s Disease Reports (open access—all content is free)
Q: As to specific health topics, I would love to see someone address all these Instagram ads targeted to women that claim “You only need to ‘balance your hormones’ to lose weight, get ripped, etc.” What does this mean? Which hormones are they all talking about? They all seem to be selling a workout program and/or supplements or something similar, as they are ads, after all. Is there any science behind this stuff or is it mostly hot air, as I suspect?
Thank you for asking this, as your question prompted yesterday’s main feature, What Does “Balancing Your Hormones” Even Mean?
That’s a great suggestion also about addressing ads (and goes for health-related things in general, not just hormonal stuff) and examining their claims, what they mean, how they work (if they work!), and what’s “technically true but may
be misleading* cause confusion”*We don’t want companies to sue us, of course.
Only, we’re going to need your help for this one, subscribers!
See, here at 10almonds we practice what we preach. We limit screen time, we focus on our work when working, and simply put, we don’t see as many ads as our thousands of subscribers do. Also, ads tend to be targeted to the individual, and often vary from country to country, so chances are good that we’re not seeing the same ads that you’re seeing.
So, how about we pull together as a bit of a 10almonds community project?
- Step 1: add our email address to your contacts list, if you haven’t already
- Step 2: When you see an ad you’re curious about, select “share” (there is usually an option to share ads, but if not, feel free to screenshot or such)
- Step 3: Send the ad to us by email
We’ll do the rest! Whenever we have enough ads to review, we’ll do a special on the topic.
We will categorically not be able to do this without you, so please do join in—Many thanks in advance!
