While carbon steel can be an excellent material for cookware, there are some potential health concerns to be aware of. One concern is that carbon steel can leach iron into food. This is especially true if the cookware is used to cook acidic foods, such as tomatoes or lemons.
While iron is an essential nutrient, too much iron can lead to gastrointestinal problems or even liver damage. Therefore, it is important to use carbon steel cookware with care and avoid cooking acidic foods in it on a regular basis.
Another potential health concern is that carbon steel cookware can also leach chromium and nickel into food. Both of these substances are considered to be carcinogens, so it is important to take steps to avoid contact with them.
