Followed you back, I never ever thought about iron and cast iron!!! Thanks so much for the information!!! We've been looking at Chromium because they tell me I'm borderline type 2 diabetic. Turns out just 200 micro-grams of chromium (About 2 ten thousandths the weight of a small paperclip) per day can cure type 2 diabetes in some people. I'm sure it wouldn't take much iron from your pans to make a difference.
