I would agree w/the coatings argument generally, although they say that aluminun taken in leads to alzheimers–I would also refer you to WEB MD. Personally, I’m more concerned w/non-stick coatings on pans and what happens as they deteriorate through cooking. Also think about non-stick sprays which you have to check the ingredients on because many of them have SILICONE in them. Do you really want to cook that into your food? It’s NOT a food product but, in some applications, an industrial lubricant. Most restaurants don’t use non-stick pans, and use an oil, like olive oil or higher burn temperature safflower oil for cooking.
Oh, back to aluminum cans–stop drinking soda anyway before you get diabetes, and beer always tastes better in a bottle. Cheers, and happy eating!
