I appreciate you updating your comment with an informed update that contradicted your initial argument. When a consumer chemical is discovered to be harmful, there's a tendency from companies to ask their research chemists to come up with a new chemical that shares the same beneficial properties but without the baggage of the provably dangerous chemical. There's a VERY good chance that the new chemical simply hasn't…

I do not trust BPA-free plastics either. I have switched from cans to tetrapaks where possible. My confusion came from some misleading industry documents I read which suggested that PFOA/PFOS/C8 had been replaced with a process that did not require fluorosurfactants. I feel like the information about these chemicals is so confusing, it's hard for a non-chemist like me to understand.

Would it not be better to switch to glass? Isn't tetrapak lined with plastic too?

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…

Seems like a lot of good advice, with one notable exception being induction kitchen appliances.

I think electromagnetic radiation is the area where I'm most reckless because of smartphone, laptop, WiFi Router... It's hard to avoid. But on the plus side this is probably one of the most well-researched areas with fewest gaps. The only uncertainty for me concerns what amount of electromagnetic radiation is safe but I guess quite a lot.

I cook eggs on cast iron without them sticking, but it requires maintenance on the seasoning. The trick is to use some butter when cooking with eggs, and they slide right off. A quick wipe with a paper towel and the pan is clean (leaving butter residue helps keep it oiled for next time). Cast iron is a pain to clean if you burn food and the burnt pieces stick, but the investment into learning how to cook with it is w…

The thing you need to be careful with using a cast iron pan is to not go too high heat. Since they can withstand a higher heat from other pans there is a risk when doing so as it creates a carcinogenic compound. There's some concern that because cast-iron pans can sustain high heat, they may produce chemicals known as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), which are linked to an incre…

Indeed. Any kind of burning or charring of food is causing really complex chemistry, and with organic molecules will likely produce aromatics, etc. (benzene is the prototypical aromatic and is present in cooking oil fumes: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4029104/ ). I think about this a lot when we’re cautioned about the presence of extremely minuscule amounts of industrial chemicals, some of the same that are present in charred food.

The study didn’t actually find anything related to cookware. Modern Teflon in the US doesn’t expose people to PFOA/PFOS like old version did due to new regulations. The chemicals could also be entering peoples body’s through drinking water or bioaccumulation in meat or plants. You should throw away nonstick cookware from before 2013, but new nonstick cookware sold in the US does not have PFOA. I believe the EU follow…

Yup. Chefs rarely use nonstick cookware outside of baking or specifically making omelettes. For the majority of their uses, it's either stainless, cast iron, or enameled cast iron. Non-stick got its foothold when the feds went on their "fat is bad for you" kick. They took all the fat out and added sugar to products to fix the texture. Proteins stick to steel when the steel isn't sufficiently hot before food is placed…

> Chefs rarely use nonstick cookware outside of baking or specifically making omelette. Citation needed? It sounds implausible to me that a majority of professional cooks seek to make their own job harder when they've got seven other dishes to make by tending a nonnonstick pan.

The main reason I know of is that a nonstick coated pan will not survive long with the bulk way they wash their dishes. You'd also have to keep a separate set of non-metal spatulas and such.

It set us up the DOCUMENTARY for great justice https://www.imdb.com/title/tt7689910/ Teflon is the most biologically sinister chemical. We need to hold the entire petrol-chemical industry to account. A dear friend of mine is the niece of one of the most successful board members of Shell. Shell is likely the most corrupt-environmentally-speaking companies on the globe. (history of When we went to dinner, they were sha…

> Teflon is the most biologically sinister chemical.

Teflon is pretty much the most non-toxic chemical you can find. There is no PFAS in the final product.

Yes, we should regulate manufacturing to make sure there is no PFAS released when making Teflon, but there is zero issue with using it.

Cast iron is also very heavy, and hard to clean if you get anything stuck to it. You can’t really soak or wash it with soap/water without re-seasoning it or it’ll rust. It has its upsides if you put in the work. I’ve given up and opted for mid-range non-stick (coated steel and/or copper, not anodized aluminum) or high end stainless.

> if you get anything stuck to it We bought these Lodge scrappers and they remove anything stuck to it. https://www.lodgecastiron.com/product/pan-scrapers?sku=SCRAP... Hot water and this kind of brush is all you need to clean cast iron: https://www.lodgecastiron.com/product/scrub-brush?sku=SCRBRS...

Those scrapers are made of plastic. I wonder if that has some forever chemicals. lol

>That feels like a decent trade off to me comparing years of life lost from liver cancer to time spent scraping scrambled eggs off of pans.

Are you sure you meant that just how it reads like? I mean your life isn't something I want you trading for a while scraping your frying pan. Please forgive my impertinence, but if you're so down on your own value I can't help but stop and ask.[edit] ask if you're ok?

Most of the replacements are probably no better than BPA - https://www.sciencedirect.com/science/article/pii/S0300483X1...

Due to our permission-first society, manufacturers can just replace BPA with a similar analogue, claim that it's BPA-free (which is technically true, but doesn't mention that the replacement is probably similarly problematic), and likely charge a premium for it.

> Eggs overeasy without breaking the yolk is really hard though. This is strange to hear from a professional chef. I cook eggs overeasy on my cast iron all the time. What works for me is preheating the pan on moderate heat for a minute or two, putting in a bit of butter, and using a metal spatula. Haven't had a broken egg in forever. I've certainly found you need less oil to prevent sticking on a well-seasoned cast i…

i guess it matters how much oil and butter you're adding.

I add heaps of oil, and never have trouble cleaning my stainless steel pans.

But the whole “clean eating” thing seems to vilify any kind of cooking fat, and guests often give me the “guess we’re not on a diet today”. But from what I recall, cooking oil is not the thing driving the obesity pandemic, and the innocent muffin they had at work would easily be several multiples of the cooking oil, calorie-wise.
