Does anyone know if the hard annodized aluminum is better for your health than the regular aluminum as far as not promoting alzheimer's, etc. I have never used aluminum cookware and one of my hostess' just brought up this subject with me and I don't know what to say. And what about the non stick caoting, is it safe? I know that the old kind, the teflon, is hazadous to the health. What about the one pampered chef uses? Does anyone know of any studies done that would relate to this. Thanks
