wow, that's pretty far reaching. ya know, like the old saying said "I may be stupid, but I'm not smart", after many many years of using non-stick metal pans/pots, it eventually dawned on me that one of the things not sticking was the teflon coating...... and after some more passing of time and more flakign away of said non-stick surface, the question eventually occured to me "gee, where is all that non-stick stuff going when it's not sticking any more ?"....... and at some subsequent time it finally occured to me that it might be going down my throat tiny piece by tiny piece.
So as far as cooking goes, what does this relegate us to.....holding meat and stuff over a fire with a hickory stick?
