So people kind of knew asbestos was harmful wayyy before it mostly stopped being used in 1979 (USA). But, it was still used constantly in many industries and ended up everywhere. What do you think is an example of something we find out is DRASTICALLY harmful 10-50 years from now? My guess would be screen time.
And teflon scratches easy, and then you eat all the tiny little flakes every time you cook. Teflon is especially super bad, very carcinogenic.
I hate it, I don’t use it unless absolutely necessary. I make do with steel and cast iron. Nothing is worth having permanently contaminated food, day in day out, over years and decades.
