Healthy cookware is stainless steel, cast iron, ceramic and glass. Pans are made of metal because they are good conductors of heat. Cookware is made from a variety of metals, with different abilities to withstand and conduct heat depending on the weight and type of metal. When acidic ingredients, like tomato sauce, are cooked in pans made of aluminum, copper, or unseasoned cast iron, trace amounts of molecules from the metal can leach into the food, Stainless steel does not leach into the food, is very strong, can resist damage from cooking, doesn’t rust or tarnish easily, and keeps its shine. However, as stainless steel doesn’t conduct heat as well as other metals, it should be paired with copper or aluminum in a process called cladding. Metal is bonded in the cladding process under intense pressure and heat with stainless steel on the outer layers. Cooking with glass and ceramic baking dishes is healthy and good for even browning. Nonstick pans are easy to clean, but they are toxic to your health and to the environment during their manufacturing process. The fumes from a smoking nonstick pan can kill a pet bird in the kitchen. A seasoned cast iron pan develops nonstick properties as the oils used in cooking fuse with the surface of the pan and is a much healthier alternative. Buying healthy cookware, clad stainless steel, seasoned cast iron, ceramic titanium, glass Pyrex, is a good investment for your family’s health and for the environment.
