Does This Practice Really Hold A Candle To Evidence-Based Medicine?
In Tuesday’s newsletter, we asked you your opinion of ear candling, and got the above-depicted, below-described set of responses:
- Exactly 50% said “Under no circumstances should you put things in your ear and set fire to them”
- About 38% said “It is a safe, drug-free way to keep the ears free from earwax and pathogens”
- About 13% said “Done correctly, thermal-auricular therapy is harmless and potentially beneficial”
This means that if we add the two positive-to-candling answers together, it’s a perfect 50:50 split between “do it” and “don’t do it”.
(Yes, 38%+13%=51%, but that’s because we round to the nearest integer in these reports, and more precisely it was 37.5% and 12.5%)
So, with the vote split, what does the science say?
First, a quick bit of background: nobody seems keen to admit to having invented this. One of the major manufacturers of ear candles refers to them as “Hopi” candles, which the actual Hopi tribe has spent a long time asking them not to do, as it is not and never has been used by the Hopi people. Other proposed origins offered by advocates of ear candling include Traditional Chinese Medicine (not used), Ancient Egypt (no evidence of such whatsoever), and Atlantis:
Quackwatch | Why Ear Candling Is Not A Good Idea
It is a safe, drug-free way to keep the ears free from earwax and pathogens: True or False?
False! In a lot of cases of alternative therapy claims, there’s an absence of evidence that doesn’t necessarily disprove the treatment. In this case, however, it’s not even an open matter; its claims have been actively disproven by experimentation:
- It doesn’t remove earwax; on the contrary, experimentation “showed no removal of cerumen from the external auditory canal. Candle wax was actually deposited in some“
- It doesn’t remove pathogens, and the proposed mechanism of action for removing pathogens, that of the “chimney effect”: the idea that the burning candle creates a vacuum that draws wax out of the ear along with debris and bacteria, simply does not work; on the contrary, “Tympanometric measurements in an ear canal model demonstrated that ear candles do not produce negative pressure”.
- It isn’t safe; on the contrary, “Ear candles have no benefit in the management of cerumen and may result in serious injury”
In a medium-sized survey (n=122), the following injuries were reported:
- 13 x burns
- 7 x occlusion of the ear canal
- 6 x temporary hearing loss
- 3 x otitis externa (this also called “swimmer’s ear”, and is an inflammation of the ear, accompanied by pain and swelling)
- 1 x tympanic membrane perforation
Indeed, authors of one paper concluded:
❝Ear candling appears to be popular and is heavily advertised with claims that could seem scientific to lay people. However, its claimed mechanism of action has not been verified, no positive clinical effect has been reliably recorded, and it is associated with considerable risk.
No evidence suggests that ear candling is an effective treatment for any condition. On this basis, we believe it can do more harm than good and we recommend that GPs discourage its use❞

Under no circumstances should you put things in your ear and set fire to them: True or False?
True! It’s generally considered good advice to not put objects in general in your ears.
Inserting flaming objects is a definite no-no. Please leave that for the Cirque du Soleil.
You may be thinking, “but I have done this and suffered no ill effects”, which seems reasonable, but is an example of survivorship bias in action—it doesn’t make the thing in question any safer, it just means you were one of the one of the ones who got away unscathed.
If you’re wondering what to do instead… Ear oils can help with the removal of earwax (if you don’t want to go get it sucked out at a clinic—the industry standard is to use a suction device, which actually does what ear candles claim to do). For information on safely getting rid of earwax, see our previous article:

Walnuts vs Brazil Nuts – 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 walnuts to Brazil nuts, we picked the walnuts.
Why?
Talking macros first, they are about equal in protein, carbs, fats, and fiber; their composition is almost identical in this regard. However, looking a little more closely at the fats, Brazil nuts have more than 2x the saturated fat, while walnuts have nearly 2x the polyunsaturated fat. So, we’ll declare the macros category a moderate win for walnuts.
The category of vitamins is not balanced; walnuts have more of vitamins A, B2, B3, B5, B6, B9, C, and choline, while Brazil nuts have more of vitamins B1 and E. A clear and easy win for walnuts.
The category of minerals is interesting, because of one mineral in particular. First let’s mention: walnuts have more iron and manganese, while Brazil nuts have more calcium, copper, magnesium, phosphorus, potassium, and selenium. Taken at face value, this is a clear win for Brazil nuts. However…
About that selenium… Specifically, it’s more than 391x higher, and a cup of Brazil nuts would give nearly 10,000x the recommended daily amount of selenium. Now, selenium is an essential mineral (needed for thyroid hormone production, for example), and at the RDA it’s good for good health. Your hair will be luscious and shiny. However, go much above that, and selenium toxicity becomes a thing, you may get sick, and it can cause your (luscious and shiny) hair to fall out. For this reason, it’s recommended to eat no more than 3–4 Brazil nuts per day.
There is one last consideration, and this is oxalates; walnuts are moderately high in oxalates (>50mg/100g) while Brazil nuts are very high in oxalates (>500mg/100g). This won’t affect most people at all, but if you have pre-existing kidney problems (including a history of kidney stones), you might want to go easy on oxalate-containing foods.
For most people, however, walnuts are a very healthy choice, and outshine Brazil nuts in most ways.

Bitter Melon vs Winter Melon – 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 bitter melon to winter melon, we picked the bitter.
Why?
Did you remember the “bitter is better” dictum that goes for most plant-based foods? It certainly stands in this case!
A note on nomenclature before we begin: these two fruits are also known as the bitter gourd and the wax gourd, respectively (amongst many other names for each), but we went with what seems to be their most common names.
In terms of macros, the bitter melon has more than 13x the protein (and actually adding up to a meaningful amount, at 5.3g/100g), as well as more fiber for the same carbs, making it the better choice all around.
When it comes to vitamins, the bitter melon has a lot more of vitamins A, B1, B2, B3, B6, B7, B9, and C, while the winter melon boasts only more vitamin B5. As in, the vitamin that’s in all foods (even its scientific name means “from everywhere”) and in which it’s pretty much impossible to be deficient unless literally starving. All in all, an easy and clear win for bitter melon.
In the category of minerals, we see a similar story: the bitter melon has very much more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and selenium, while the winter melon has a modest double-dose of zinc—hardly comparable to, say, bitter melon having over 100x the potassium content, and indeed, in all minerals except zinc, bitter melon had 4x–100x more. Another clear and overwhelming win for the bitter melon.
Looking up polyphenols, we see that the bitter melon also wins in that regard, shocking nobody, with an impressive polyphenolic profile, especially rich in luteolins and catechins of various kinds.
In short, enjoy either or both, but there’s a clear winner here, and it’s the bitter melon.

Do CBD Gummies Work?
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 Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I take CBD gummies. I don’t know if they are worth buying. Can you find a study on the effectiveness of gummies❞
If you take them, and you’re not sure whether they’re worth it, then it sounds like you’re not getting any observable benefit from them?
If so, that would seem to answer your question, since presumably the reason that you are taking them is for relaxation and/or pain relief, so if you’re not getting the results you want, then no, they are not worth it.
However! CBD gummies are an incredibly diverse and not-well-studied product, so far, given the relative novelty of their legality. By diverse we mean, they’re not well-standardized.
In other words: the CBD gummies you get could be completely unlike CBD gummies from a different source.
CBD itself (i.e. in forms other than just gummies, and mostly as oil) has been studied somewhat better, and we did a main feature on it here:
And while we’re at it:
Cannabis Myths vs Reality ← This one is about cannabis products in general, and includes discussion of THC content and effects, which might not be so relevant to you, but may to some readers.
Companies selling CBD and CBD gummies may make bold claims that are not yet backed by science, so if you are buying them for those reasons, you might want to be aware:

One thing that we would add is that even though CBD is generally recognized as safe, it is possible to overdose on CBD gummies, so do watch your limits:

Peony Against Inflammation & More
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.
Yes, this is about the flower, especially white peony (Paeonia lactiflora), and especially the root thereof (Paeoniae radix alba). Yes, the root gets a different botanical name but we promise it is the same plant. You will also read about its active glycoside paeoniflorin, and less commonly, albiflorin (a neuroprotective glycoside present in the root).
It’s one of those herbs that has made its way out of Traditional Chinese Medicine and into labs around the world.
It can be ingested directly as food, or as a powder/capsule, or made into tea.
Anti-inflammatory
Peony suppresses inflammatory pathways, which thus reduces overall inflammation. In particular, this research review found:
❝Pharmacologically, paeoniflorin exhibits powerful anti-inflammatory and immune regulatory effects in some animal models of autoimmune diseases including Rheumatoid Arthritis (RA) and Systemic Lupus Erythematosus (SLE)❞
The reviewers also (albeit working from animal models) suggest it may be beneficial in cases of kidney disease and liver disease, along with other conditions.
Here’s a larger review, which also has studies involving humans (and in vivo studies), that found it to effectively help treat autoimmune conditions including rheumatoid arthritis and psoriasis, amongst others:
❝Modern pharmacological research on TGP is based on the traditional usage of PRA, and its folk medicinal value in the treatment of autoimmune diseases has now been verified. In particular, TGP has been developed into a formulation used clinically for the treatment of autoimmune diseases.
Based on further research on its preparation, quality control, and mechanisms of action, TGP is expected to eventually play a greater role in the treatment of autoimmune diseases. ❞
(TGP = Total Glucosides of Paeony)
Antidepressant / Anxiolytic
It also acts as a natural serotonin reuptake inhibitor (as per many pharmaceutical antidepressants), by reducing the expression of the serotonin transporter protein:
Gut Microbiota-Based Pharmacokinetics and the Antidepressant Mechanism of Paeoniflorin
(remember, most serotonin is produced in the gut)
Here’s how that played out when tested (on rats, though):
Against PMS and/or menopause symptoms
Peony is widely used in Traditional Chinese Medicine to reduce these symptoms in general. However, we couldn’t find a lot of good science for that, although it is very plausible (as the extract contains phytoestrogens and may upregulate estrogen receptors while dialling down testosterone production). Here’s the best we could find for that, and it’s a side-by-side along with licorice root:
❝Paeoniflorin, glycyrrhetic acid and glycyrrhizin decreased significantly the testosterone production but did not change that of delta 4-androstenedione and estradiol. Testosterone/delta 4-androstenedione production ratio was lowered significantly by paeoniflorin, glycyrrhetic acid and glycyrrhizin❞
Effect of paeoniflorin, glycyrrhizin and glycyrrhetic acid on ovarian androgen production
(note: that it didn’t affect estradiol levels is reasonable; it contains phytoestrogens after all, not estradiol—and in fact, if you are taking estradiol, you might want to skip this one, as its phytoestrogens could compete with your estradiol for receptors)

Chili Chestnut, Sweet Apricot, & Whipped Feta Toasts
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 is a delightful breakfast or light lunch option, full of gut-healthy ingredients and a fair list of healthy polyphenols too.
You will need
- ½ baguette, sliced into ½” slices; if making your own, feel free to use our Delicious Quinoa Avocado Bread recipe. If buying shop-bought, a sourdough baguette will likely be the healthiest option, and tasty too.
- 4 oz feta cheese; if you are vegan, a plant-based version will work in culinary terms, but will have a different (less gut-healthy) nutritional profile, as plant-based cheeses generally use a lot of coconut oil and potato starch, and are not actually fermented.
- 1 tbsp yogurt; your preference what kind; live-cultured with minimal additives is of course best—and this time, plant-based is also just as good, healthwise, since they are fermented and contain more or less the same beneficial bacteria, and have a good macro profile too.
- 4 oz precooked chestnuts, finely chopped
- 6 dried apricots, finely chopped
- ¼ bulb garlic, grated
- 2 tsp harissa paste
- 1 tsp black pepper, coarse ground
- ¼ tsp MSG or ½ tsp low-sodium salt
- Extra virgin olive oil, for frying
- Optional garnish: finely chopped chives
Method
(we suggest you read everything at least once before doing anything)
1) Combine the feta and yogurt in a small, high-speed blender and process into a smooth purée. If it isn’t working, add 1 tbsp kettle-hot water and try again.
2) Heat the oil in a skillet over a medium heat; add the garlic and when it starts to turn golden, add the chestnuts and harissa, as well as the black pepper and MSG/salt. Stir for about 2 minutes, and then stir in the apricots and take it off the heat.
3) Toast the baguette slices under the grill. If you’re feeling bold about the multitasking, you can start this while still doing the previous step, for optimal timing. If not, simply doing it in the order presented is fine.
4) Assemble: spread the whipped feta over the toast; add the apricot-chestnut mixture, followed by the finely chopped chives if using, and serve immediately:
Enjoy!

Six Ways To Eat For Healthier Skin
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.
Sadia Badiei, the nutritionist-chef of “Pick Up Limes” fame, has advice:
More than skin-deep:
We’ll not keep them a mystery; here are the six points of focus:
1. Collagen and skin elasticity
Collagen is the structural protein that provides firmness and elasticity to the skin, but its production decreases with age, resulting in about a 1% annual loss starting at age 20. To support collagen, a diet rich in protein is essential, including foods like beans, lentils, tofu, tempeh, nuts, and seeds. They can’t do their work alone though; vitamins C and E play a critical role in collagen production and repair, protecting against damage from sun exposure, pollution, and free radicals. Vitamin E can be found in almonds, sunflower seeds, leafy greens, peanuts, and avocados, while vitamin C is abundant in citrus fruits, bell peppers, and broccoli.
2. Skin healing and zinc
Zinc is critical for wound healing and reducing inflammation, making it particularly helpful in managing skin conditions such as acne, eczema, psoriasis, and rosacea. Great dietary sources of zinc include nutritional yeast, pumpkin, sesame, and hemp seeds, as well as legumes and whole grains. However, zinc absorption can be hindered by phytate levels in some foods. Soaking, sprouting, or fermenting foods where possible can correct for that and improve zinc absorption.
3. Dry skin and hydration
Dry skin can result from many things, including dry air, hot water, abrasive soaps, and certain medications. While moisturizers provide external hydration, dietary omega-3 fats are essential for improving the skin’s barrier function, helping it retain moisture. Plant-based sources of omega-3s include walnuts, hemp seeds, chia seeds, flax seeds, and algae-based supplements. Staying adequately hydrated also supports overall health of course (everything runs on water in one way or another, after all), which indirectly benefits skin hydration, although drinking additional water only helps if dehydration is present.
4. Sebum regulation
Sebum, an oily substance that lubricates the skin, can cause issues like acne and blackheads when overproduced. Hormonal fluctuations and diet both influence sebum levels (in either direction). High glycemic index foods, such as sweetened beverages, refined grains, and sugary snacks, can lead to spikes in insulin, which in turn stimulates excess sebum production. In contrast, low glycemic index foods like vegetables, whole grains, tofu, nuts, and seeds regulate blood sugar and help manage sebum production, promoting clearer skin without an excess or a shortage of sebum.
5. Gut health and skin
The gut-skin connection means that imbalances in gut bacteria can contribute to skin issues like acne, eczema, and psoriasis. Supporting gut health involves increasing the diversity of beneficial bacteria through probiotic-rich foods. Fermented options like plant-based yogurts, kimchi, miso, sauerkraut, and kombucha not only improve gut microbiome health but also positively impact skin health by reducing inflammation and improving overall skin conditions.
6. Inflammation and skin health
Chronic inflammation is associated with so many health issues, and when it comes to skin, that includes acne, rosacea, and even wrinkles. Anti-inflammatory foods, especially those rich in antioxidants, can mitigate these effects and improve skin elasticity, smoothness, and color. Diets centered around fruits, vegetables, and other plant-based foods provide the necessary nutrients to combat inflammation, showcasing the significant role of nutrition in promoting radiant, healthy skin.
