A downside of non-stick pans are the unknown side effects of the non-stick substance used, though.

Teflon is inert unless you really overheat it.

  It's not the teflon that is my concern, it's what they have used to get the teflon to stick to the pan. read this : https://en.wikipedia.org/wiki/GenX#Pollution https://en.wikipedia.org/wiki/GenX#Pollution

    Pans themselves don't contain significant levels of PFAs, but I agree about the environmental issues.

  The 'f' in 'teflon' is the F from the periodic table. Florine is remarkably not inert. Teflon is a relatively stable Florine compound. But as you say, it can destabilize when the pan is used within a few sigma of ideal cooking temperature.

    Reactive elements make stable compounds. e.g. sodium + chlorine -> sodium chloride.

    There is no FL in periodic table. And Teflon is not as stable as believed.

      He said 'F', not 'FL'. It is on the periodic table: https://en.wikipedia.org/wiki/Fluorine https://en.wikipedia.org/wiki/Fluorine

  I can't access the page from tor, but i'd be interested in seeing those studies. Do they account for extreme heat applied, or for mechanical harm to the coating? These two scenarios are mostly inevitable over the lifespan of a non-stick pan, and they're typically blamed for being the cause of the actual food poisoning.

I might be concerned about teflon and similar non-stick coatings, but not really about ceramics. Humanity has been using ceramics for ages, and we haven't found any adverse affects yet.

  Just make sure it's PFAS free and not just PF(X) free for some X; 3M is hell bent on getting this shit into your system
  - frazbin 4y ago
    e.g. some of the 'copper coated' stuff that is 'PFOA' free

      It's the same idiocy we have to endure with BPA-free plastics.

  > Humanity has been using ceramics for ages, and we haven't found any adverse affects yet. Porous ceramics can easily breed bacteria, good and bad. And glazes on ceramics can contain all kinds of delightful compounds that can leach out. You certainly don’t want to eat or breathe unfired glaze. As for ceramic nonstick cookware, I’m not convinced that such a thing exists. I think that “ceramic” coatings are actually sol-gel, and I can’t find a straight answer as to what is in them. They do advertise that they are fluoropolymer-free, and they seem to be stable to rather higher temperatures than PTFE.
