My mother always told me that coatings on non-stick cookware were carcinogenic. She also told me the following (which I follow but never actually fact-checked):

- When doing dishes by hand, make sure to always rinse the soap off completely.

- Do not consume hot water straight out of the tap; always take it out cold and boil it as a separate step (because hot water carries more lead and other metals from the inside of the pipes?)

- Do not eat burnt (or partially burnt) food (carcinogenic).

- Avoid induction kitchen appliances (radiation).

- Avoid chewing plastic (pthalates/endocrine disruptors).

- Avoid cooking with seed oils or other polyunsaturated oils - These are good raw, but not heated as it breaks the bonds in the oil and turns bad. For cooking, use saturated fats (but mono-saturated fats like olive oil are OK too).

- Avoid processed foods as much as possible (and chemicals such as coloring agents and preservatives).

- Avoid eating too much instant noodles (due to coating on noodles).

- Avoid soaps and shampoos which produce a lot of foam (avoid sodium lauryl sulfate and cocamidopropyl-betaine).

- Avoid any medication which affects the brain.

- Make sure that bedroom gets plenty of sunlight during the day to prevent dust mites.

- Don't over-sanitize your environment; lack of exposure to germs can lead to allergies?

- Rinse your mouth out well after brushing teeth (don't consume too much fluoride).

- After taking antibiotics, eat yogurt and/or probiotic supplements to rebuild gut bacteria. I was told this long before research about gut microbes was mainstream.

- Avoid eating too much predatory fish like Tuna (mercury).

- Swimming in the sea is good for you. It has healing properties?

Anyway, kind of random but I've always wanted to share these in case it helps anyone. I do think it helps to be cautious even when the science is limited or has gaps. Our modern society tends to err on the side of reckless consumption instead of cautious consumption. Remember, the financial incentive of all companies in a capitalist system is to deny all downsides because it mitigates legal liabilities. Think of Big Tobacco 'doctors recommend smoking' campaigns in the 1930s to 1950s; it makes sense to assume that every industry we have today is similar. So the science (which is funded by these companies) will always be biased towards neglect ("don't worry, it's totally safe and effective") rather than caution ("It's probably safe in small quantities but you may want to avoid it anyway just in case"). The media will never promote the second approach.
