Scientists have proven that many non-stick cooking surfaces off-gas toxic fumes and can leach chemicals into your food. Aluminum and copper cookware can also be problematic, and exposure to these metals can lead to unintended consequences in the body. Stainless steel cookware can be used daily without any health concerns, is non-reactive and safe – and you don’t have to worry about little flakes from non-stick pots and pans getting into your food.
