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)

    You are misunderstanding the problem. John Oliver, like Veritasium in the post’s video, is talking about the health risks of PFOS like C8 and GenX which are PFAS used in the production of other PFAS like Teflon. PFOS are able to enter the bloodstream and have proven carcinogenic effects. However, although PFOS are used in the production of Teflon, they are not found on a non-stick pan. Teflon molecules are too big and too inert to enter the bloodstream and will simply pass through the body when ingested. So scratching a non-stick pan and eating the flakes wouldn’t really do anything, I don’t think I’d have to prove that by doing it.
