Yes, stainless steel cookware comprises a food-grade alloy of iron, chromium, nickel, and other elements. When exposed to air, the chromium content oxidizes and forms a shiny white layer of chromium oxide that we see on stainless steel cookware. It is neutral and food-safe and does not react to acidic foods. Hence, cooking or serving hot dishes on them will cause no harm. They are free of toxins like BPA and other harmful chemicals. You can use them for cooking food regularly. Unlike other metal cookware, stainless steel does not release carcinogenic materials. The nutritional benefits while cooking in stainless steel are leaps and bounds. They are also safer to use than non-stick cookware.
