If you look hard enough, you will probably find that just about everything is bad for you. If Dupont hadn't developed 'Teflon', then somebody else would have. I use and will continue to use 'Teflon' coated frying pans. They have excellent non-stick properties. I also use PTFE sprays to lubricate sliding doors etc.
My other saucepans are mostly Hard anodised aluminium or stainless steel with an encapsulated aluminium base.. Aghhh Aluminium - oh dear that's poisonous isn't it - don't panic, don't panic (UK readers will understand the quote)
