Hello! I've seen some reports online about Teflon (PTFE) non-stick pans and PFOA which is used to produce them being a health concern. (I gather if Teflon gets above 260C it can breakdown into other chemicals.) This page: https://www.cancer.org/cancer/cancer-causes/teflon-and-perfluorooctanoic-acid-pfoa.html states that Teflon isn't suspected of causing cancer. What about other health problems? We all know how official establishment advice can be wrong - anyone have any useful info, please? Many thanks!
