Cast iron, ceramic and glass cookware are made from natural materials and are considered safer cookware options than non-stick cookware. Glass is the most inert cookware material, meaning it doesn't release potentially harmful compounds into food.
Ceramic and cast iron cookware are safe alternatives that offer even heat distribution and no chemical coatings. Most non-stick cookware uses a perfluorooctanoic acid coating that releases 15 types of gases that are believed to have detrimental health effects. Aluminum cookware leaches aluminum if exposed to acidic foods. This may cause consumption of aluminum as high as 10 milligrams, which may increase the risk of Alzheimer's disease and cancer.
