Also, cast iron is known to cure anemia in women, and it has been tested for thousands of years and is well understood. It is not experimental. Also, really, how hard is it to put some oil in a pan and let that coat the pan before you start cooking? My friends complain that their food burns in an iron pan, which I think is a surprising complaint. The solution to burning has been known for centuries: just put some oil or butter in the pan, and use a reasonable flame.
