> do people really cook in non-stick pans without any sort of oil?
Definitely!
As much as I generally love it, e.g. pancakes with olive oil sound like a dubious idea, taste-wise.
Regarding frying things in olive oil, I was also under the impression that it's not particularly heat-stable and unhealthy substances can start forming at relatively low temperatures?
Oh lol, yeah, I wouldn't use olive oil on pancakes. That's definitely a butter situation.
As for high heat with olive oil, I'm not sure about it being unhealthy or not. I just found this overview [1], and it seems like there isn't great evidence. I again hadn't considered it, since it's something my ancestors have done for thousands of years. Sample size of one family, but my grandmother lived to her 90s and my great-aunt is still walking around Paris in her mid-90s!
