"It's good for you. Cast iron cookware leaches small amounts of iron into food, so you get a little extra iron each time you use it. Almost anyone, especially women in their child bearing years, will benefit from this."

Not 100% sure if I'm correct here, but this may not be true. Just like the iron in the Kellogg's cereal wasn't edible and even bad for your teeth, this iron probably isn't digestible either. It has to be iron in its mineral state, not regular iron.
