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)
There is (according to the video) concrete evidence for both acute toxicity as well as causal carcinogenic effects when it comes to PFOA.
The distinction here is between long-chained Fluoropolymers like Teflon, which are completely benign as far as evidence suggests; and fluoroalkyl acids (like PFOA), that are short-chained, can enter the bloodstream, and mimic the structure of fatty acids thus being able to bond to stuff in our body.
No, there’s a very minor causational link that has been classified as “needs further study”

Its extremely far away from “concrete evidence”, that’s what Im talking about when saying this video was hypebole.
Many places are classifying it as potentially hazardous to be safe, because:
