It dumbs down discussion, as well taking it off topic and turning it nasty. Important topics deserve better than that. Unimportant topics too, actually.
I bet that the butter itself is worse for your health than the minuscule PFAS you are getting from your pan.
Except it isn’t. Try letting melted cheese, or pretty much any starch (pasta, rice, oatmeal, etc) sit in stainless for a while and then see how non-stick it is. It will glue itself to stainless but on non-stick it will slide right off.
I’m not arguing in favor of non-stick, and avoid it when possible, but we can’t also be making inaccurate claims either.
Also, cast iron, even when seasoned, would still stick quite a bit in the above scenario (and I can’t imagine any scenario where I’d want to cook starches like that in cast iron).
Also, vegetable oils are incredibly high in omega-6's which compete with omega-3's for the same enzymes. In general the literature suggests we should be consuming about a 4:1 ratio for Omega-3's to Omega-6 fatty acids. Corn-based oil, for example, has a 1:60 ratio
I think avoiding excessive vegetable oil intake is still a good idea
