It’s always been bad for you. The process to create Teflon pans results in PFAS being released into streams and the atmosphere. Literally just creating the product has poisoned the earth, you don’t need to use it at all. But yes, I stopped buying Teflon stuff too. It’s the only way to reduce demand and manufacturing.
Recent studies have shown that the pans offgas without even being used or at low temperatures, but yes just buying them at all is the main problem.
