Mythbusting Cookware Materials

In Wednesday’s newsletter, we asked you what kind of cookware you mostly use, and got the above-depicted, below-described, set of responses:
- About 45% said stainless steel
- About 21% said cast iron
- About 15% said non-stick (e.g. Teflon)
- About 9% said enamel
- About 6% said aluminum
- And 1 person selected “something else”, but then commented to the contrary, writing “I use all of the above”
So, what does the science say about these options?
Stainless steel cookware is safe: True or False?
True! Assuming good quality and normal use, anyway. There really isn’t a lot to say about this, because it’s very unexciting. So long as it is what it is labelled as: there’s nothing coating it, nothing comes out of it unless you go to extremes*, and it’s easy to clean.
*If you cook for long durations at very high temperatures, it can leach nickel and chromium into food. What this means in practical terms: if you are using stainless steel to do deep-frying, then maybe stop that, and also consider going easy on deep-frying in general anyway, because obviously deep-frying is unhealthy for other reasons.
Per normal use, however: pretty much the only way (good quality) stainless steel cookware will harm you is if you touch it while it’s hot, or if it falls off a shelf onto your head.
That said, do watch out for cheap stainless steel cookware that can contain a lot of impurities, including heavy metals. Since you probably don’t have a mass spectrometer and/or chemistry lab at home to check for those impurities, your best guard here is simply to buy from a reputable brand with credible certifications.
Ceramic cookware is safe: True or False?
True… Most of the time! Ceramic pans usually have metal parts and a ceramic cooking surface coated with a very thin layer of silicon. Those metal parts will be as safe as the metals used, so if that’s stainless steel, you’re just as safe as the above. As for the silicon, it is famously inert and body-safe (which is why it’s used in body implants).
However: ceramic cookware that doesn’t have an obvious metal part and is marketed as being pure ceramic, will generally be sealed with some kind of glaze that can leach heavy metals contaminants into the food; here’s an example:
Lead toxicity from glazed ceramic cookware
Copper cookware is safe: True or False?
False! This is one we forgot to mention in the poll, as one doesn’t see a lot of it nowadays. The copper from copper pans can leach into food. Now, of course copper is an important mineral that we must get from our diet, but the amount of copper that that can leach into food from copper pans is far too much, and can induce copper toxicity.
In addition, copper cookware has been found to be, on average, highly contaminated with lead:
Non-stick cookware contaminates the food with microplastics: True or False?
True! If we were to discuss all the common non-stick contaminants here, this email would no longer fit (there’s a size limit before it gets clipped by most email services).
Suffice it to say: the non-stick coating, polytetrafluoroethylene, is itself a PFAS, that is to say, part of the category of chemicals considered environmental pollutants, and associated with a long list of health issues in humans (wherein the level of PFAS in our bloodstream is associated with higher incidence of many illnesses):
You may have noticed, of course, that the “non-stick” coating doesn’t stick very well to the pan, either, and will tend to come off over time, even if used carefully.
Also, any kind of wet cooking (e.g. saucepans, skillets, rice cooker inserts) will leach PFAS into the food. In contrast, a non-stick baking tray lined with baking paper (thus: a barrier between the tray and your food) is really not such an issue.
We wrote about PFAS before, so if you’d like a more readable pop-science article than the scientific paper above, then check out:
PFAS Exposure & Cancer: The Numbers Are High
Aluminum cookware contaminates the food with aluminum: True or False?
True! But not usually in sufficient quantities to induce aluminum toxicity, unless you are aluminum pans Georg who eats half a gram of aluminum per day, who is a statistical outlier and should not be counted.
That’s a silly example, but an actual number; the dose required for aluminum toxicity in blood is 100mg/L, and you have about 5 liters of blood.
Unless you are on kidney dialysis (because 95% of aluminum is excreted by the kidneys, and kidney dialysis solution can itself contain aluminum), you will excrete aluminum a lot faster than you can possibly absorb it from cookware. On the other hand, you can get too much of it from it being a permitted additive in foods and medications, for example if you are taking antacids they often have a lot of aluminum oxide in them—but that is outside the scope of today’s article.
However, aluminum may not be the real problem in aluminum pans:
❝In addition, aluminum (3.2 ± 0.25 to 4.64 ± 0.20 g/kg) and copper cookware (2.90 ± 0.12 g/kg) were highly contaminated with lead.
The time and pH-dependent study revealed that leaching of metals (Al, Pb, Ni, Cr, Cd, Cu, and Fe, etc.) into food was predominantly from anodized and non-anodized aluminum cookware.
More metal leaching was observed from new aluminum cookware compared to old. Acidic food was found to cause more metals to leach during cooking.❞
~ the same paper we cited when talking about copper
Cast iron cookware contaminates the food with iron: True or False?
True, but unlike with the other metals discussed, this is purely a positive, and indeed, it’s even recommended as a good way to fortify one’s diet with iron:
The only notable counterpoint we could find for this is if you have hemochromatosis, a disorder in which the body is too good at absorbing iron and holding onto it.
Thinking of getting some new cookware?
Here are some example products of high-quality safe materials on Amazon, but of course feel free to shop around:
Stainless Steel | Ceramic* | Cast Iron
*it says “non-stick” in the description, but don’t worry, it’s ceramic, not Teflon etc, and is safe
Bonus: rice cooker with stainless steel inner pot
Take care!

Neurotransmitter Cheatsheet
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.
Which Neurotransmitter?
There are a lot of neurotransmitters that are important for good mental health (and, by way of knock-on effects, physical health).
However, when pop-science headlines refer to them as “feel-good chemicals” (yes but which one?!) or “the love molecule” (yes but which one?!) or other such vague names when referring to a specific neurotransmitter, it’s easy to get them mixed up.
So today we’re going to do a little disambiguation of some of the main mood-related neurotransmitters (there are many more, but we only have so much room), and what things we can do to help manage them.
Dopamine
This one predominantly regulates reward responses, though it’s also necessary for critical path analysis (e.g. planning), language faculties, and motor functions. It makes us feel happy, motivated, and awake.
To have more:
- eat foods that are rich in dopamine or its precursors such as tyrosine (bananas and almonds are great)
- do things that you find rewarding
Downsides: is instrumental in most addictions, and also too much can result in psychosis. For most people, that level of “too much” isn’t obtainable due to the homeostatic system, however.
See also: Rebalancing Dopamine (Without “Dopamine Fasting”)
Serotonin
This one predominantly helps regulate our circadian rhythm. It also makes us feel happy, calm, and awake.
To have more:
- get more sunlight, or if the light must be artificial, then (ideally) full-spectrum light, or (if it’s what’s available) blue light
- spend time in nature; we are hardwired to feel happy in the environments in which we evolved, which for most of human history was large open grassy expanses with occasional trees (however, for modern purposes, a park or appropriate garden will suffice).
Downsides: this is what keeps us awake at night if we had too much light before bed, and also too much serotonin can result in (potentially fatal) serotonin syndrome. Most people can’t get that much serotonin due to our homeostatic system, but some drugs can force it upon us.
See also: Seasonal Affective Disorder Strategies
Oxytocin
This one predominantly helps us connect to others on an emotional level. It also makes us feel happy, calm, and relaxed.
To have more:
- hug a loved one (or even just think about doing so, if they’re not available)
- look at pictures/videos of cute puppies, kittens, and the like—this triggers a similar response
Downsides: negligible. Socially speaking, it can cause us to drop our guard, most for most people most of the time, this is not a problem. It can also reduce sexual desire—it’s in large part responsible for the peaceful lulled state post-orgasm. It’s not responsible for the sleepiness in men though; that’s mostly prolactin.
See also: Only One Kind Of Relationship Promotes Longevity This Much!
Adrenaline
This one predominantly affects our sympathetic nervous system; it elevates heart rate, blood pressure, and other similar functions. It makes us feel alert, ready for action, and energized.
To have more:
- listen to a “power anthem” piece of music. What it is can depend on your musical tastes; whatever gets you riled up in an empowering way.
- engage in something competitive that you feel strongly about while doing it—or by the same mechanism, a solitary activity where the stakes feel high even if it’s actually quite safe (e.g. watching a thriller or a horror movie, if that’s your thing).
Downsides: its effects are not sustainable, and (in cases of chronic stress) the body will try to sustain them anyway, which has a deleterious effect. Because adrenaline and cortisol are closely linked, chronically high adrenal action will tend to mean chronically high cortisol also.
See also: Lower Your Cortisol! (Here’s Why & How)
Some final words
You’ll notice that in none of the “how to have more” did we mention drugs. That’s because:
- a drug-free approach is generally the best thing to try first, at the very least
- there are simply a lot of drugs to affect each one (or more), and talking about them would require talking about each drug in some detail.
However, the following may be of interest for some readers:

Burn – by Dr. Herman Pontzer
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 have reasons to want to focus on our metabolism. Speed it up to burn more fat; slow it down to live longer. Tweak it for more energy in the day. But what actually is it, and how does it work?
Dr. Herman Pontzer presents a very useful overview of not just what our metabolism is and how it works, but also why.
The style of the book is casual, but doesn’t skimp on the science. Whether we are getting campfire stories of Hadza hunter-gatherers, or an explanation of the use of hydrogen isotopes in metabolic research, Dr. Pontzer keeps things easy-reading.
One of the main premises of the book is that our caloric expenditure is not easy to change—if we exercise more, our bodies will cut back somewhere else. After all, the body uses energy for a lot more than just moving. With this in mind, Dr. Pontzer makes the science-based case for focusing more on diet than exercise if weight management is our goal.
In short, if you’d like your metabolism to be a lot less mysterious, this book can help render a lot of science a lot more comprehensible!

Holy Basil: What Does (And Doesn’t) It Do?
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.
First, a quick clarification:
- Ocimum sanctum is the botanical name given to what in English we call holy basil, and is what we will be discussing today. It’s also called “tulsi“, so if you see that name around, it is the same plant.
- Ocimum basilicum is the botanical name given to culinary basil, the kind you will find in your local supermarket. This one looks similar, but it has a different taste (culinary basil is sweeter) and a different phytochemical profile, and is certainly not the same plant.
We have touched on holy basil before, in our article:
Herbs For Evidence-Based Health & Healing
…where we listed that it helps boost immunity, per:
It’s popularly also consumed in the hopes of getting many other benefits, including:
- Calming effects on the mood (anti-stress)
- Accelerated wound-healing
- Anticancer activity
So, does it actually do those things?
Against stress
We literally couldn’t find anything. It’s often listed as being adaptogenic (reduces stress) in the preamble part of a given paper’s abstract, but we could find no study in any reputable journal that actually tested its effects against stress, and any citations for the claim just link to other papers that also include it in the preamble—and while “no original research” is a fine policy for, say, Wikipedia, it’s not a great policy when it comes to actual research science.
So… It might! There’s also no research (that we could find) showing that it doesn’t work. But one cannot claim something works on the basis of “we haven’t proved it doesn’t”.
For wound healing
Possibly! We found one (1) paper with a small (n=29) sample, and the results were promising, but that sample size of 29 was divided between three groups: a placebo control, holy basil, and another herb (which latter worked less well). So the resultant groups were tiny, arguably to the point of statistical insignificance. However, taking the study at face value and ignoring the small sample size, the results were very promising, as the holy basil group enjoyed a recovery in 4 weeks, rather than the 5 weeks recovery time of the control group:
Herbal remedies for mandibular fracture healing
An extra limitation that’s worth noting, though, is that healing bone is not necessarily the same as healing other injuries in all ways, so the same results might not be replicated in, say, organ or tissue injuries.
Against cancer
This time, there’s lots of evidence! Its mechanism of action appears to be severalfold:
- Anti-inflammatory
- Antioxidant
- Antitumor
- Chemopreventive
Because of the abundance of evidence (including specifically against skin cancer, lung cancer, breast cancer, and more), we could list studies all day here, but instead we’ll just link this one really good research review that has a handy navigation menu on the right, where you can see how it works in each of the stated ways.
Here’s the paper:

Using the”Task Zero” approach
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.
“Jonathan Frakes Asks You Things” Voice:
- Do you ever find yourself in a room and wonder what you’re doing there?
- Or set about a to-do list, but get quickly distracted by side-quests?
- Finally get through to a person in a call center, they ask how they can help, and your mind goes blank?
- Go to the supermarket and come out with six things, none of which were the one you came for?
This is a “working memory” thing and you’re not alone. There’s a trick that can help keep you on track more often than not:
Don’t try to overburden your working memory. It is very limited (this goes for everyone to a greater or lesser degree). Instead, hold only two tasks at once:
- Task zero (what you are doing right now)
- Task one (your next task)
When you’ve completed task zero, task one becomes the new task zero, and you can populate a new task one from your to-do list.
This way, you will always know what you’re doing right now, and what you’re doing next, and your focus will be so intent on task zero, that you will not get sidetracked by task seventeen!
Happy focusing

Mocktails – by Moira Clark
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’ve reviewed books about quitting alcohol before (such as this one), but today’s is not about quitting, so much as about enjoying non-alcoholic drinks; it’s simply a recipe book of zero-alcohol cocktails, or “mocktails”.
What sets this book apart from many of its kind is that every recipe uses only natural and fresh ingredients, rather than finding in the ingredients list some pre-made store-bought component. Instead, because of its “everything from scratch” approach, this means:
- Everything is reliably as healthy as the ingredients you use
- Every recipe’s ingredients can be found easily unless you live in a food desert
Each well-photographed and well-written recipe also comes with a QR code to see a step-by-step video tutorial (or if you get the ebook version, then a direct link as well).
Bottom line: this is the perfect mocktail book to have in (and practice with!) before the summer heat sets in.

Mung Beans vs Red Lentils – 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 mung beans to red lentils, we picked the lentils.
Why?
Both are great! But the lentils win on overall nutritional density.
In terms of macros, they have approximately the same carbs and fiber, and are both low glycemic index foods. The deciding factor is that the lentils have slightly more protein—but it’s not a huge difference; both are very good sources of protein.
In the category of vitamins, mung beans have more of vitamins A, E, and K, while red lentils have more of vitamins B1, B2, B3, B5, B6, B9, C, and choline. An easy win for lentils.
When it comes to minerals, again both are great, but mung beans have more calcium and magnesium (hence the green color) while red lentils have more copper, iron, manganese, phosphorus, potassium, selenium, and zinc. Another clear win for lentils.
Polyphenols are also a worthy category to note here; both have plenty, but red lentils have more, especially flavonols, anthocyanidins, proanthocyanidins, and anthocyanins (whence the red color).
In short: enjoy both, because diversity is almost always best. But if you’re picking one, red lentils are the most nutritious of the two.
