I use some teflon coated, copper, stainless steel and cast iron. The food we eat, the way it's grown and processed will probably kill us before the way we cook it. Grill or whatever type of pan, none of them are that great health wise. I think all the junk in the air from pollution, and the sizing on our clothing and fabrics in the store is worse for us to breathe in than the stuff from our pots and pans.
