Gymnema Sylvestre: The “Sugar Destroyer”

The Leaf That Stops Sugar From “Working”
Gymnema sylvestre, whose botanical name in Greek and Latin means “naked thread of the woods”, and is in various Indian languages referred to be names that translate as “sugar destroyer”, has the most prosaic name in Australia: the Australian cowplant.
In English it’s mostly called by the Greek “gymnema” though, so that’s what we’ll call it here.
You may be wondering: “the sugar destroyer?”
And no, it doesn’t actually destroy sugar. But it does do quite a bit of sugar-related stuff. Here’s the science for it…
Blocks sugar receptors in your tongue
This is what it is most well-known for, and it is a topical effect, so you won’t get this from a pill, but you will get this from the leaves, or from drinking it as a tea made from the leaves.
The effect last several hours, during which time your ability to taste sweetness will be reduced, which not only makes sweet foods less appealing because they’re no longer tasting sweet, but also, once you get used to it, when you actually do taste sweet foods, they will now taste too sweet.
So, it doesn’t just temporarily curb cravings; it offers a long-term escape from such, too.
You may be wondering: “what about artificially sweetened foods and drinks?”
And the answer is: yes, it blocks perception of the sweetness of those too:
Effects of sweetness perception and caloric value of a preload on short term intake ← this study used gymnema as the sweetness-blocker, testing sugary drinks, aspartame-sweetened drinks, and unsweetened drinks
Blocks sugar receptors in the gut, too
Long story short: this slows down the absorption of sugars from the gut, thus resulting in a gentler blood sugar curve, minimizing spikes, and (because of the body’s use of blood sugars as it goes) overall lower blood sugar levels.
Want the long version? Here it is:
Benefits beyond sugar-blocking
It also prevents the accumulation of triglycerides in muscles and the liver, as well as decreasing fatty acid accumulation in the blood. In simpler terms: it lowers LDL (“bad” cholesterol”, including VLDL). As a bonus, it increases HDL (“good” cholesterol) while it’s at it.
The vast majority of the studies for this are on rats and mice though, of which you can see very many listed in the “similar articles” under this systematic review of studies:
A systematic review of Gymnema sylvestre in obesity and diabetes management
We did find one good quality human RCT, testing gymnema along with several other treatments (they found that each worked, and/but using a combination yielded the best results):
(the title says “on weight loss”, but rest assured the study also gives information about its effects on total cholesterol, LDL, HDL, overall triglycerides, and serum leptin levels, as well as excretion of urinary fat metabolites—suffice it to say, they were thorough)
Is it safe?
It has a good safety profile in general, but if you are diabetic, proceed with caution and discuss it with your endocrinologist, since it will be affecting your blood sugar levels and insulin levels. While it’s probably not enough to replace metformin or similar, it is enough that taking it carelessly could result in an unexpected hypo.
Similarly, if you have any heart condition and especially if you are being treated for that with medication, do speak with your cardiologist since its antilipemic action could potentially lower your cholesterol more than expected, and doctors don’t like surprises.
As ever, no list of contraindications will be exhaustive, and we can’t speak for your specific situation, so checking with your pharmacist/doctor is always a good idea.

Pomegranate vs Figs – 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 pomegranate to figs, we picked the pomegranate.
Why?
In terms of macros, pomegranate has a lot more protein* and fiber, while the fig has more carbs. Thus, a win for pomegranate.
*Why such protein in a fruit? In both cases, it’s mostly from the seeds, which in both cases, we’re eating. However, pomegranates have a much greater seed-to-mass ratio than figs, and thus, a correspondingly higher amount of protein. Also some fats from the seeds, again more than figs, but the margin of difference is smaller, and not really enough to be of relevance.
In the category of vitamins, pomegranates lead with more of vitamins B1, B5, B9, C, E, K, and choline, while figs have more of vitamins A, B3, and B6. The largest margins of difference are in vitamins B9, E, and K, so all in pomegranate’s favor.
The minerals scene is closer to even; pomegranate has more copper, phosphorus, potassium, selenium, and zinc, while figs have more calcium, iron, magnesium, and manganese. Thus, a 5:4 lead for pomegranate, and the larger margins of difference are again for pomegranate.
In short, enjoy both, but pomegranates are the more nutritionally dense. Also, don’t throw away the peel! Dry it, and turn it into a powdered supplement—see our linked article below, for why:

Break the Cycle – by Dr. Mariel Buqué
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.
Intergenerational trauma comes in two main varieties: epigenetic, and behavioral.
This book covers both. There’s a lot more we can do about the behavioral side than the epigenetic, but that’s not to say that Dr. Buqué doesn’t have useful input in the latter kind too.
If you’ve read other books on epigenetic trauma, then there’s nothing new here—though the refresher is always welcome.
On the behavioral side, Dr. Buqué gives a strong focus on practical techniques, such as specific methods of journaling to isolate trauma-generated beliefs and resultant behaviors, with a view to creating one’s own trauma-informed care, cutting through the cycle, and stopping it there.
Which, of course, will not only be better for you, but also for anyone who will be affected by how you are (e.g. now/soon, hopefully better).
As a bonus, if you see the mistakes your parents made and are pretty sure you didn’t pass them on, this book can help you troubleshoot for things you missed, and also to improve your relationship with your own childhood.
Bottom line: if you lament how things were, and do wish/hope to do better in terms of mental health for yourself now and generations down the line, this book is a great starting point.

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.

What Happens To Your Body When You Stop Drinking Alcohol
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.
Immediately after we stop drinking is rarely when we feel our best. But how long is it before we can expect to see benefits, instead of just suffering?
Timeline
After stopping drinking alcohol for…
- Seconds: the liver starts making progress filtering out toxins and sugars; ethanol starts to leave the system
- 1 hour: fatigue sets in as the body uses a lot of energy to metabolize and eliminate alcohol. However, sleep quality (if one goes to sleep now) is low because alcohol disrupts the brain patterns required for restful sleep
- 6–12 hours: the immune system starts recovering from the suppression caused by alcohol
- 24 hours: immune system is back to normal; withdrawal symptoms may occur in the case of heavy drinkers
- 3–5 days: resting blood pressure begins to drop, as stress levels decrease (alcohol may seem anxiolytic, but it is actually anxiogenic; it just masks its own effect in this regard). Also, because of insulin responses improving, appetite reduces. The liver, once it has finished dealing your last drinking session (if you used to drink all the time, it probably had a backlog to clear), can now begin to make repairs on itself.
- 1 week: skin will start looking better, as antidiuretic hormone levels neutralize, leading to a healthier maintenance of hydration
- 2 weeks: cognitive abilities improve as the brain begins to make progress in repairing itself. At the same time, kidneys start to heal.
- 3–4 weeks: the liver begins to regenerate in earnest. You may wonder what took it so long given the liver’s famous regenerative abilities, but in this case, the liver was also the organ that took the most damage from drinking, so its regeneration gets off to a slow start (in contrast, if the liver had “merely” suffered physical trauma, such as being shot, stabbed,
or eaten by eagles,it’d start regenerating vigorously as soon as the immediate wound-response had been tended to). Once it is able to pick up the pace though, overall health improves, as the liver can focus on breaking down other toxins. - 1–2 months: the heart is able to repair itself, and start to become stronger again (dependent on other lifestyle factors, of course).
- 3 months and more: bodily repairs continue (for example, the damage to the liver is often so severe that it can take quite a bit longer to recover completely, and repairs in the brain are always slow, for reasons beyond the scope of this article). Looking at the big picture, at this point we also see other benefits, such as reduced cancer risks.
In short… It’s never too soon to stop, but it’s also never too late, unless you are going to die in the next few days. So long as you’ll be in the land of the living for a few days yet, there’s time to enjoy the benefits of stopping.
Most importantly: the timeline for the most important repairs is not as long as many people might think, and that itself can be very motivating.

The Magic of L-theanine
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.
All The Benefits Of Caffeine And More, Without The Drawbacks? What’s The Catch?
It just takes one extra supplement.
For many of us, our morning brew is practically a ritual, but caffeine can also cause all kinds of problems ranging from caffeine jitters to caffeine crashes to caffeine addiction and withdrawal. Surely, something could be better?
Well, yes it could! You doubtlessly know about green tea’s antioxidant properties, but its amino acid, l-theanine (which can be taken as a supplement with coffee, if you don’t enjoy green tea) has so much more to offer:
- L-theanine has been found to reduce stress responses—and let’s face it, when we most want/need a coffee is often when facing stress
- It also reduces anxiety, making it a very safe “downer” without the problems of, for example, alcohol—or other potentially addictive substances
- It’s far more than just that, though! Paradoxically, l-theanine also improves alertness (what other calming things promote alertness? Not so many)
- Part of its trick is that it also improves accuracy—whereas stimulants like caffeine may produce a twitchy, jumpy, responsiveness, l-theanine’s signature effect is a calm state of sharp readiness. Caffeine works by stimulating the adrenal gland and increasing blood pressure, while simultaneously blocking adenosine receptors so that your body doesn’t notice its own tiredness—which is why you’re likely to crash later, when the tiredness that had been masked, all hits at once. Instead, l-theanine taken with caffeine acts as a moderator of that, making for a longer, gentler curve. In terms of subjective experience, what this can mean for many people is: no more caffeine jitters!
- All this means that while l-theanine can boost all kinds of cognitive function, including alertness and accuracy, many like to take in the evening as it can also promote a good night’s sleep, ready to be at your best the next day.
- How much to take? 200mg is a commonly used dosage, which in supplement terms is usually a single capsule. A lot easier to take than the 40 cups of green tea that this dosage would otherwise be!

Track Your Blood Sugars For Better Personalized Health

- Calories: Is Cutting Calories The Key To Healthy Long Life?
- Sleep: A Head-To-Head Of Google and Apple’s Top Apps For Getting Your Head Down
- Heart Rate Zones: Heart Rate Zones, Oxalates, & More
About calories: this writer (it’s me, hi) opines that intermittent fasting has the same benefits as caloric restriction, without the hassle of counting, and is therefore superior. I also personally find fasting psychologically more pleasant. However, our goal here is to be informative, not prescriptive, and some people may have reasons to prefer CR to IF!
Examples that come to mind include ease of adherence in the case of diabetes management, especially Type 1, or if one’s schedule (and/or one’s “medications that need to be taken with food” schedule) does not suit IF.
And now for the blood…
A rising trend in health enthusiasts presently is the use of Continuous Glucose Monitors (CGMs), which do exactly what is sounds like they do: they continually monitor glucose. Specifically, the amount of it in your blood.
Of course, these have been in use in diabetes management for years; the technology is not new, but the application of the technology is.
A good example of what benefits a non-diabetic person can gain from the use of a CGM is Jessie Inchauspé, the food scientist of “Glucose Revolution” and “The Glucose Goddess Method” fame.
By wearing a CGM, she was able to notice what things did and didn’t spike her blood sugars, and found that a lot of the things were not stuff that people knew/advised about!
For example, much of diabetes management (including avoiding diabetes in the first place) is based around paying attention to carbs and little else, but she found that it made a huge difference what she ate (or didn’t) with the carbs. By taking many notes over the course of her daily life, she was eventually able to isolate these patterns, showed her working-out in The Glucose Revolution (there’s a lot of science in that book), and distilled that information into bite-size (heh) advice such as:
10 Ways To Balance Blood Sugars
That’s great, but since people like Inchauspé have done the work, I don’t have to, right?
You indeed don’t have to! But you can still benefit from it. For example, fastidious as her work was, it’s a sample size of one. If you’re not a slim white 32-year-old French woman, there may be some factors that are different for you.
All this to say: glucose responses, much like nutrition in general, are not a one-size-fits-all affair.
With a CGM, you can start building up your own picture of what your responses to various foods are like, rather than merely what they “should” be like.
This, by the way, is also one of the main aims of personalized health company ZOE, which crowdsourced a lot of scientific data about personalized metabolic responses to standardized meals:
Not knowing these things can be dangerous
We don’t like to scaremonger here, but we do like to point out potential dangers, and in this case, blindly following standardized diet advice, if your physiology is not standard, can have harmful effects, see for example:

Where can I get a CGM?
