(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”:

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:

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:

The Checklist Manifesto – by Dr. Atul Gawande
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.
Dr. Gawande, himself a general surgeon, uses checklists a lot. He is, unequivocally, an expert in his field. He “shouldn’t” need a checklist to tell him to do such things as “Check you have the correct patient”. But checklists are there as a safety net. And, famously, “safety regulations are written in blood”, after all.
And, who amongst us has never made such a “silly” error? From forgetting to turn the oven on, to forgetting to take the handbrake off, it takes only a momentary distraction to think we’ve done something we haven’t.
You may be wondering: why a whole book on this? Is it just many examples of the usefulness of checklists? Because I’m already sold on that, so, what else am I going to get out of it?
Dr. Gawande also explains in clear terms:
- How to optimize “all necessary steps” with “as few steps as possible”
- The important difference between read-do checklists and do-confirm checklists
- To what extent we should try to account for the unexpected
- How to improve compliance (i.e., making sure you actually use it, no matter how tempting it will be to go “yeah this is automatic for me now” and gloss over it)
- The role of checklists in teams, and in passing on knowledge
…and more.
Bottom line: if you’ve ever tried to make tea without putting the tea-leaves in the pot, this is the book that will help you avoid making more costly mistakes—whatever your area of activity or interest.

Egg Noodles vs Rice Noodles – 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 egg noodles to rice noodles, we picked the egg noodles.
Why?
It was close—these are both quite mediocre foods. They’re neither amazing for the health nor appalling for the health (in moderation). They are both relatively low in nutrients, but they are also low in anti-nutrients, i.e. things that have a negative effect on the health.
Their mineral profiles are similar; both are a source of selenium, manganese, phosphorus, copper, and iron. Not as good as many sources, but not devoid of nutrients either.
Their vitamin profiles are both pitiful; rice noodles have trace amounts of various vitamins, and egg noodles have only slightly more. While eggs themselves are nutritious, the processing has robbed them of much of their value.
In terms of macros, egg noodles have a little more fat (but the fats are healthier) and rice noodles have a lot more carbs, so this is the main differentiator, and is the main reason we chose the egg noodles over the rice noodles. Both have a comparable (small) amount of protein.
In short:
- They’re comparable on minerals, and vitamins here are barely worth speaking about (though egg noodles do have marginally more)
- Egg noodles have a little more fat (but the fats are healthier)
- Rice noodles have a lot more carbs (with a moderately high glycemic index, which is relatively worse—if you eat them with vegetables and fats, then that’ll offset this, but we’re judging the two items on merit, not your meal)

Broccoli vs Cabbage – 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 broccoli to cabbage, we picked the broccoli.
Why?
Here we go once again pitting two different cultivars of the same species (Brassica oleracea) against each other, and/but once again, there is one that comes out as nutritionally best.
In terms of macros, broccoli has more protein, carbs, and fiber, while they are both low glycemic index foods. The differences are small though, so it’s fairest to call this category a tie.
When it comes to vitamins, broccoli has more of vitamins A, B1, B2, B3, B5, B6, B7, B9, C, E, K, and choline, while cabbage is not higher in any vitamins. It should be noted that cabbage is still good for these, especially vitamins C and K, but broccoli is simply better.
In the category of minerals, broccoli has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while cabbage is not higher in any minerals. Again though, cabbage is still good, especially in calcium, iron, and manganese, but again, broccoli is simply better.
Of course, enjoy either or both! But if you want the nutritionally densest option, it’s broccoli.

Self-Care for Tough Times – by Suzy Reading
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 note on the author: while not “Dr. Reading”, she is a “CPsychol, B Psych (Hons), M Psych”; a Chartered Psychologist specializing in wellbeing, stress management and facilitation of healthy lifestyle change. So this is coming from a place of research and evidence!
The kinds of “tough times” she has in mind are so numerous that listing them takes two pages in the book, so we won’t try here. But suffice it to say, there are a lot of things that can go wrong for us as humans, and this book addresses how to take care of ourselves mindfully in light of them.
The author takes a “self-care is health care” approach, and goes about things with a clinical mindset and/but a light tone, offering both background information, and hands-on practical advice.
Bottom line: there may be troubles ahead (and maybe you’re in the middle of troubles right now), but there’s always room for a little sunshine too.

Stickers and wristbands aren’t a reliable way to prevent mosquito bites. Here’s why
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.
Protecting yourself and family from mosquito bites can be challenging, especially in this hot and humid weather. Protests from young children and fears about topical insect repellents drive some to try alternatives such as wristbands, patches and stickers.
These products are sold online as well as in supermarkets, pharmacies and camping stores. They’re often marketed as providing “natural” protection from mosquitoes.
But unfortunately, they aren’t a reliable way to prevent mosquito bites. Here’s why – and what you can try instead.
Why is preventing mosquito bites important?
Mosquitoes can spread pathogens that make us sick. Japanese encephalitis and Murray Valley encephalitis viruses can have potentially fatal outcomes. While Ross River virus won’t kill you, it can cause potentially debilitating illnesses.
Health authorities recommend preventing mosquito bites by: avoiding areas and times of the day when mosquitoes are most active; covering up with long sleeved shirts, long pants, and covered shoes; and applying a topical insect repellent (a cream, lotion, or spray).
I don’t want to put sticky and smelly repellents on my skin!
While for many people, the “sting” of a biting mosquitoes is enough to prompt a dose of repellent, others are reluctant. Some are deterred by the unpleasant feel or smell of insect repellents. Others believe topical repellents contain chemicals that are dangerous to our health.
However, many studies have shown that, when used as recommended, these products are safe to use. All products marketed as mosquito repellents in Australia must be registered by the Australian Pesticides and Veterinary Medicines Authority; a process that provides recommendations for safe use.
How do topical repellents work?
While there remains some uncertainty about how the chemicals in topical insect repellents actually work, they appear to either block the sensory organs of mosquitoes that drive them to bite, or overpower the smells of our skin that helps mosquitoes find us.
Diethytolumide (DEET) is a widely recommended ingredient in topical repellents. Picaridin and oil of lemon eucalyptus are also used and have been shown to be effective and safe.
How do other products work?
“Physical” insect-repelling products, such as wristbands, coils and candles, often contain a botanically derived chemical and are often marketed as being an alternative to DEET.
However, studies have shown that devices such as candles containing citronella oil provide lower mosquito-bite prevention than topical repellents.
A laboratory study in 2011 found wristbands infused with peppermint oil failed to provide full protection from mosquito bites.
Even as topical repellent formulations applied to the skin, these botanically derived products have lower mosquito bite protection than recommended products such as those containing DEET, picaridin and oil of lemon eucalyptus.
Wristbands infused with DEET have shown mixed results but may provide some bite protection or bite reduction. DEET-based wristbands or patches are not currently available in Australia.
There is also a range of mosquito repellent coils, sticks, and other devices that release insecticides (for example, pyrethroids). These chemicals are primarily designed to kill or “knock down” mosquitoes rather than to simply keep them from biting us.
What about stickers and patches?
Although insect repellent patches and stickers have been available for many years, there has been a sudden surge in their marketing through social media. But there are very few scientific studies testing their efficacy.
Our current understanding of the way insect repellents work would suggest these small stickers and patches offer little protection from mosquito bites.
At best, they may reduce some bites in the way mosquito coils containing botanical products work. However, the passive release of chemicals from the patches and stickers is likely to be substantially lower than those from mosquito coils and other devices actively releasing chemicals.
One study in 2013 found a sticker infused with oil of lemon eucalyptus “did not provide significant protection to volunteers”.
Clothing impregnated with insecticides, such as permethrin, will assist in reducing mosquito bites but topical insect repellents are still recommended for exposed areas of skin.
Take care when using these products
The idea you can apply a sticker or patch to your clothing to protect you from mosquito bites may sound appealing, but these devices provide a false sense of security. There is no evidence they are an equally effective alternative to the topical repellents recommended by health authorities around the world. It only takes one bite from a mosquito to transmit the pathogens that result in serious disease.
It is also worth noting that there are some health warnings and recommendations for their use required by Australian Pesticides and Veterinary Medicines Authority. Some of these products warn against application to the skin (recommending application to clothing only) and to keep products “out of reach of children”. This is a challenge if attached to young children’s clothing.
Similar warnings are associated with most other topical and non-topical mosquito repellents. Always check the labels of these products for safe use recommendations.
Are there any other practical alternatives?
Topical insect repellents are safe and effective. Most can be used on children from 12 months of age and pose no health risks. Make sure you apply the repellent as a thin even coat on all exposed areas of skin.
But you don’t need “tropical strength” repellents for short periods of time outdoors; a range of formulations with lower concentrations of repellent will work well for shorter trips outdoors. There are some repellents that don’t smell as strong (for example, children’s formulations, odourless formulations) or formulations that may be more pleasant to use (for example, pump pack sprays).
Finally, you can always cover up. Loose-fitting long-sleeved shirts, long pants, and covered shoes will provide a physical barrier between you and mosquitoes on the hunt for your or your family’s blood this summer.

The Worst Way to Wake Up (and What to Do Instead)
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.
Not everyone is naturally inclined to be a morning person, but there are things we can do to make things go more easily for our brains!
Cause for alarm?
Dr. Tracey Marks, psychiatrist, explains the impact of our first moments upon awakening, and what that can do to/for us in terms of sleep inertia (i.e. grogginess).
Sleep inertia is worse when waking from deep sleep—and notably, we don’t naturally wake directly from deep sleep unless we are externally aroused (e.g. by an alarm clock).
Dr. Marks suggests the use of more gradual alarms, including those with soft melodies, perhaps birdsong or other similarly gentle things (artificial sunlight alarms are also good), to ease our transition from sleeping to waking. It might take us a few minutes longer to be woken from sleep, but we’re not going to spend the next hour in a bleary-eyed stupor.
