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):

Presence of Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) in Food Contact Materials (FCM) and Its Migration to Food

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:

Effect of cooking food in iron-containing cookware on increase in blood hemoglobin level and iron content of the food: A systematic review

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!

  • The Energy Plan – by James Collins

    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.

    There’s a lot of conflicting advice out there about how we should maintain our energy levels, for example:

    • Eat fewer carbs!
    • Eat more carbs!
    • Eat slow-release carbs!
    • Eat quick-release carbs!
    • Practise intermittent fasting!
    • Graze constantly throughout the day!
    • Forget carbs and focus on fats!
    • Actually it’s all about B-vitamins!

    …and so on.

    What Collins does differently is something much less-often seen:

    Here, we’re advised on how to tailor our meals to our actual lifestyle, taking into account the day we actually have each day. For example:

    • What will our energy needs be for the day?
    • Will our needs be intense, or long, or both, or neither?
    • What kind of recovery have we had, or do we need, from previous activities?
    • Do we need to replace lost muscle glycogen, or are we looking to trim the fat?
    • Are we doing a power-up or just maintenance today?

    Rather than bidding us have a five-way spreadsheet and do advanced mathematics for every meal, though, Collins has done the hard work for us. The book explains the various principles in a casual format with a light conversational tone, and gives us general rules to follow.

    These rules cover what to do for different times of day… and also, at different points in our life (the metabolic needs of a 13-year-old, 33-year-old, and 83-year-old, are very different!). That latter’s particularly handy, as a lot of books assume an age bracket for the reader, and this one doesn’t.

    In short: a great book for anyone who wants to keep their energy levels up (throughout life’s ups and downs in activity) without piling on the pounds or starving oneself.

  • What Is Making The Ringing In Your Ears Worse?

    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. Rachael Cook, an audiologist at Applied Hearing Solutions in Phoenix, Arizona, shares her professional insights into managing tinnitus.

    If you’re unfamiliar with Tinnitus, it is an auditory condition characterized by a ringing, buzzing, or humming sound, and ffects nearly 10% of the population. We’ve written on Tinnitus, and how it can disrupt your life, in this article.

    Key Triggers for Tinnitus

    Several everyday habits can make your tinnitus louder. Caffeine and nicotine increase blood pressure, restricting blood flow to the cochlea and worsening tinnitus. Common medications, such as pain relievers, high-dose antibiotics, and antidepressants, can also exacerbate tinnitus, especially with higher or long-term dosages.

    Impact of Diet and Sleep

    Dietary choices significantly impact tinnitus. Alcohol and salt alter the fluid balance in the cochlea, increasing tinnitus perception. Alcohol changes blood flow patterns and neurotransmitter production, while high salt intake has similar effects. Poor sleep quality elevates stress levels, making it harder to ignore tinnitus signals. Addressing sleep disorders like sleep apnea and insomnia can help manage tinnitus symptoms.

    Importance of Treating Hearing Loss

    Untreated hearing loss worsens tinnitus. Nearly 90% of individuals with tinnitus have some hearing loss. Hearing aids can reduce tinnitus perception by restoring missing sounds and reducing the brain’s internal compensatory signals. Combining hearing aids with sound therapy is said to provide even greater relief.

    Read more about hearing loss in our article on the topic.

    Otherwise, for a great guide on managing tinnitus, we recommend watching Dr. Cook’s video:

  • Could ADHD drugs reduce the risk of early death? Unpacking the findings from a new Swedish study

    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.

    Attention-deficit hyperactivity disorder (ADHD) can have a considerable impact on the day-to-day functioning and overall wellbeing of people affected. It causes a variety of symptoms including difficulty focusing, impulsivity and hyperactivity.

    For many, a diagnosis of ADHD, whether in childhood or adulthood, is life changing. It means finally having an explanation for these challenges, and opens up the opportunity for treatment, including medication.

    Although ADHD medications can cause side effects, they generally improve symptoms for people with the disorder, and thereby can significantly boost quality of life.

    Now a new study has found being treated for ADHD with medication reduces the risk of early death for people with the disorder. But what can we make of these findings?

    A large study from Sweden

    The study, published this week in JAMA (the prestigious journal of the American Medical Association), was a large cohort study of 148,578 people diagnosed with ADHD in Sweden. It included both adults and children.

    In a cohort study, a group of people who share a common characteristic (in this case a diagnosis of ADHD) are followed over time to see how many develop a particular health outcome of interest (in this case the outcome was death).

    For this study the researchers calculated the mortality rate over a two-year follow up period for those whose ADHD was treated with medication (a group of around 84,000 people) alongside those whose ADHD was not treated with medication (around 64,000 people). The team then determined if there were any differences between the two groups.

    What did the results show?

    The study found people who were diagnosed and treated for ADHD had a 19% reduced risk of death from any cause over the two years they were tracked, compared with those who were diagnosed but not treated.

    In understanding this result, it’s important – and interesting – to look at the causes of death. The authors separately analysed deaths due to natural causes (physical medical conditions) and deaths due to unnatural causes (for example, unintentional injuries, suicide, or accidental poisonings).

    The key result is that while no significant difference was seen between the two groups when examining natural causes of death, the authors found a significant difference for deaths due to unnatural causes.

    So what’s going on?

    Previous studies have suggested ADHD is associated with an increased risk of premature death from unnatural causes, such as injury and poisoning.

    On a related note, earlier studies have also suggested taking ADHD medicines may reduce premature deaths. So while this is not the first study to suggest this association, the authors note previous studies addressing this link have generated mixed results and have had significant limitations.

    In this new study, the authors suggest the reduction in deaths from unnatural causes could be because taking medication alleviates some of the ADHD symptoms responsible for poor outcomes – for example, improving impulse control and decision-making. They note this could reduce fatal accidents.

    The authors cite a number of studies that support this hypothesis, including research showing ADHD medications may prevent the onset of mood, anxiety and substance use disorders, and lower the risk of accidents and criminality. All this could reasonably be expected to lower the rate of unnatural deaths.

    Strengths and limitations

    Scandinavian countries have well-maintained national registries that collect information on various aspects of citizens’ lives, including their health. This allows researchers to conduct excellent population-based studies.

    Along with its robust study design and high-quality data, another strength of this study is its size. The large number of participants – almost 150,000 – gives us confidence the findings were not due to chance.

    The fact this study examined both children and adults is another strength. Previous research relating to ADHD has often focused primarily on children.

    One of the important limitations of this study acknowledged by the authors is that it was observational. Observational studies are where the researchers observe and analyse naturally occurring phenomena without intervening in the lives of the study participants (unlike randomised controlled trials).

    The limitation in all observational research is the issue of confounding. This means we cannot be completely sure the differences between the two groups observed were not either partially or entirely due to some other factor apart from taking medication.

    Specifically, it’s possible lifestyle factors or other ADHD treatments such as psychological counselling or social support may have influenced the mortality rates in the groups studied.

    Another possible limitation is the relatively short follow-up period. What the results would show if participants were followed up for longer is an interesting question, and could be addressed in future research.

    What are the implications?

    Despite some limitations, this study adds to the evidence that diagnosis and treatment for ADHD can make a profound difference to people’s lives. As well as alleviating symptoms of the disorder, this study supports the idea ADHD medication reduces the risk of premature death.

    Ultimately, this highlights the importance of diagnosing ADHD early so the appropriate treatment can be given. It also contributes to the body of evidence indicating the need to improve access to mental health care and support more broadly.The Conversation

    When it comes to predicting age-related cognitive impairment:

    First there are genetic factors to take into account (such as the APOE4 gene for Alzheimer’s), as well as things such as age and sex.

    When it comes to sex, by the way, what matters here is hormones, which is why [it seems; this as technically as yet unproven with full rigor, but the hypothesis is sound and there is a body of evidence gradually being accumulated to support it] postmenopausal women with untreated menopause get Alzheimer’s at a higher rate and deteriorate more quickly:

    Alzheimer’s Sex Differences May Not Be What They Appear

    Next, there are obviously modifiable lifestyle factors to take into account, things that will reduce your risk such as getting good sleep, good diet, good exercise, and abstaining from alcohol and smoking, as well as oft-forgotten things such as keeping cognitively active and, equally importantly, socially active:

    How To Reduce Your Alzheimer’s Risk

    (the article outlines what matters the most in each of the above areas, by the way, so that you can get the most bang-for-buck in terms of lifestyle adjustments)

    Lastly (in the category of risk factors), there are things to watch out for in the blood such as hypertension and high cholesterol.

    Nipping it in the blood

    In new research (so new it is still ongoing, but being at year 2 of a 4-year prospective study, they have published a paper with their results so far), researchers have:

    1. started with the premise “dementia is preceded by mild cognitive impairment”
    2. then, asked the question “what are the biometric signs of mild cognitive impairment?”

    Using such tools as functional near-infrared spectroscopy (fNIRS) while the participants performed cognitive tasks, they were able to record changes in plasma levels of extracellular vesicles, assessing them with small-particle flow cytometry.

    Translating from sciencese: they gave the participants mental tasks, and while they completed them, the researchers scanned their brains and monitored blood flow and the brain’s ability to compensate for any lack of it.

    What they found:

    • in young adults, blood flow increased, facilitating neurovascular coupling (this is good)
    • in older adults, blood flow did not increase as much, but they engaged other areas of the brain to compensate, by what’s called functional connectivity (this is next best)
    • in those with mild cognitive impairment, blood flow was reduced, and they did not have the ability to compensate by functional connectivity (this is not good)

    They also performed a liquid biopsy, which sounds alarming but it just means they took some blood, and tested this for density of cerebrovascular endothelial extracellular vesicles (CEEVs), which—in more prosaic words—are bits from the cells lining the blood vessels in the brain.

    People with mild cognitive impairment had more of these brain bits in their blood than those without.

    You can read the paper itself here:

    Neurovascular coupling, functional connectivity, and cerebrovascular endothelial extracellular vesicles as biomarkers of mild cognitive impairment

    What this means

    The science here is obviously still young (being as it is still in progress), but this will likely contribute greatly to early warning signs of dementia, by catching mild cognitive impairment in its early stages, by means of a simple blood test, instead of years of wondering before getting a dementia diagnosis.

    And of course, forewarned is forearmed, so if this is something that could be done as a matter of routine upon hitting the age of, say, 65 and then periodically thereafter, it would catch a lot of cases while there’s still more time to turn things around.

    First, a couple of things that this book is not about:

    1. Self-confidence (it’s about more than merely thinking highly of oneself)
    2. Self-acceptance (it’s about more than merely settling for “good enough”)

    In contrast, it’s about loving and celebrating what is, while striving for better, for oneself and for others.

    You may be wondering: whence this “radical” in the title?

    The author argues that often, the problem with our bodies is not actually our bodies. If we have cancer, or diabetes, then sure, that’s a problem with the body. But most of the time, the “problem with our bodies” is simply society’s rejection of our “imperfect” bodies as somehow “less than”, and something we must invest time and money to correct. Hence, the need for a radical uprooting of ideas, to fix the real problem.

    Bottom line: if, like most of us, you have a body that would not entirely pass for that of a Marvel Comics superhero, this is a book for you. And if you do have a MCU body? This is also a book for you, because we have bad news for you about what happens with age.

  • Asbestos in mulch? Here’s the risk if you’ve been exposed

    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.

    Mulch containing asbestos has now been found at 41 locations in New South Wales, including Sydney parks, schools, hospitals, a supermarket and at least one regional site. Tests are under way at other sites.

    As a precautionary measure, some parks have been cordoned off and some schools have closed temporarily. Fair Day – a large public event that traditionally marks the start of Mardi Gras – was cancelled after contaminated mulch was found at the site.

    The New South Wales government has announced a new taskforce to help investigate how the asbestos ended up in the mulch.

    Here’s what we know about the risk to public health of mulch contaminated with asbestos, including “friable” asbestos, which has been found in one site (Harmony Park in Surry Hills).

    What are the health risks of asbestos?

    Asbestos is a naturally occurring, heat-resistant fibre that was widely used in building materials from the 1940s to the 1980s. It can be found in either a bonded or friable form.

    Bonded asbestos means the fibres are bound in a cement matrix. Asbestos sheeting that was used for walls, fences, roofs and eaves are examples of bonded asbestos. The fibres don’t escape this matrix unless the product is severely damaged or worn.

    A lot of asbestos fragments from broken asbestos products are still considered bonded as the fibres are not released as they lay on the ground.

    Bonded asbestos

    Friable asbestos, in contrast, can be easily crumbled by touch. It will include raw asbestos fibres and previously bonded products that have worn to the point that they crumble easily.

    The risk of disease from asbestos exposure is due to the inhalation of fibres. It doesn’t matter if those fibres are from friable or bonded sources.

    However, fibres can more easily become airborne, and therefore inhalable, if the asbestos is friable. This means there is more of a risk of exposure if you are disturbing friable asbestos than if you disturb fragments of bonded asbestos.

    Who is most at risk from asbestos exposure?

    The most important factor for disease risk is exposure – you actually have to inhale fibres to be at risk of disease.

    Just being in the vicinity of asbestos, or material containing asbestos, does not put you at risk of asbestos-related disease.

    For those who accessed the contaminated areas, the level of exposure will depend on disturbing the asbestos and how many fibres become airborne due to that disturbance.

    However, if you have been exposed to, and inhaled, asbestos fibres it does not mean you will get an asbestos-related disease. Exposure levels from the sites across Sydney will be low and the chance of disease is highly unlikely.

    The evidence for disease risk from ingestion remains highly uncertain, although you are not likely to ingest sufficient fibres from the air, or even the hand to mouth activities that may occur with playing in contaminated mulch, for this to be a concern.

    The risk of disease from exposure depends on the intensity, frequency and duration of that exposure. That is, the more you are exposed to asbestos, the greater the risk of disease.

    Most asbestos-related disease has occurred in people who work with raw asbestos (for example, asbestos miners) or asbestos-containing products (such as building tradespeople). This has been a tragedy and fortunately asbestos is now banned.

    There have been cases of asbestos-related disease, most notably mesothelioma – a cancer of the lining of the lung (mostly) or peritoneum – from non-occupational exposures. This has included people who have undertaken DIY home renovations and may have only had short-term exposures. The level of exposure in these cases is not known and it is also impossible to determine if those activities have been the only exposure.

    There is no known safe level of exposure – but this does not mean that one fibre will kill. Asbestos needs to be treated with caution.

    As far as we are aware, there have been no cases of mesothelioma, or other asbestos-related disease, that have been caused by exposure from contaminated soils or mulch.

    Has asbestos been found in mulch before?

    Asbestos contamination of mulch is, unfortunately, not new. Environmental and health agencies have dealt with these situations in the past. All jurisdictions have strict regulations about removing asbestos products from the green waste stream but, as is happening in Sydney now, this does not always happen.

    Mulch
    Mulch contamination is not new.

    What if I’ve been near contaminated mulch?

    Exposure from mulch contamination is generally much lower than from current renovation or construction activities and will be many orders of magnitude lower than past occupational exposures.

    Unlike activities such as demolition, construction and mining, the generation of airborne fibres from asbestos fragments in mulch will be very low. The asbestos contamination will be sparsely spread throughout the mulch and it is unlikely there will be sufficient disturbance to generate large quantities of airborne fibres.

    Despite the low chance of exposure, if you’re near contaminated mulch, do not disturb it.

    If, by chance, you have had an exposure, or think you have had an exposure, it’s highly unlikely you will develop an asbestos-related disease in the future. If you’re worried, the Asbestos Safety and Eradication Agency is a good source of information.The Conversation
