Did you know that microscopic levels of the teflon coating on your cooking pans can leach into your food at extremely high heat? You won't see it, but who wants to risk eating teflon? Who knows what they put in that stuff and it's a sure bet that God didn't design our guts for digesting Dupont chemicals.
The solution? Don't use anything higher than Medium High heat when cooking with teflon coated pots and pans. If you must use High heat, use a non-coated pan and some good old fashioned oil or butter.
