It seems I shouldn’t have posted this without context

TL;DW

  • yes the video is (at least partially) about Teflon, hence the cynical title

  • no, Teflon (or generally big Fluoropolymers) are not the problem. Ingesting them does nothing to you, because as long, chemically inert polymers they just pass through you from one end to the other

  • The problem are perfluoroalkyl acids: C8 (PFOA) and later substitutes such as C6/GenX, PFOS, PFHA, PFHxS which are chemicals used to start the Teflon polymerization. They are short-chained carbon-fluorine molecules that coincidentally mimic the structure of fatty acids, thus can accumulate in our bodies without a way for our bodies to break them down.

  • These chemicals leach into the environment from factories and accumulate in everything, to the point that the whole water cycle has been contaminated (yes that shit comes down everywhere with the rain)

  • There is conclusive proof that PFOA exposure is linked to a number of organ damage and cancers, particularly testicular cancer and kidney cancer, with likely links to lung and pancreatic cancer not reflected in the study due to survivor bias (they died before the study was concluded)

    I’ve not clicked and I know it’s almost certainly talking about Teflon

    So very much to do with pans, and likely anything cooked in those pans (e.g. eggs)

    Edit: okay it’s PFAS in general, Teflon is just a common type people are familiar with

        Sorry yes, you’re correct, it’s a PTFE. Which is touted as a safe alternative until you find out burning it (about 250 degrees) produces PFAS.

        Now if someone perfectly uses the pan and never leaves it on high heat without anything in it, they’re probably gonna be fine. But I’ve lived in the same house as an idiot who has done exactly that, so I’m inclined to think that it’s not an entirely uncommon thing.

        Then you’ve also got the post-use phase of the pan’s life where it could easily end up in a waste incinerator, and we already know we have a problem with PFAS hanging around in the environment.
