Cast Iron is a Chemical-Free Alternative to Nonstick Pans
Another benefit to using cast-iron pans in place of nonstick pans is that you avoid the harmful chemicals that are found in nonstick pans. The repellent coating that keeps food from sticking to nonstick pots and pans contains PFCs (perfluorocarbons), a chemical that’s linked to liver damage, cancer, developmental problems and, according to one 2011 study in the Journal of Clinical Endocrinology & Metabolism, early menopause. PFCs get released—and inhaled—from nonstick pans in the form of fumes when pans are heated on high heat. Likewise, we can ingest them when the surface of the pan gets scratched. Both regular and ceramic-coated cast-iron pans are great alternatives to nonstick pans for this reason.
