Is ceramic-coated cookware truly chemical-free?
Yes. PFAS from nonstick coatings accumulate in the body. Switch to stainless steel or cast iron.
What's actually in it
PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals used in nonstick and water-resistant coatings. They don't break down in the environment or in your body. Once PFAS get in, they build up over time.
Common kitchen sources include nonstick pans, some food wrappers, microwave popcorn bags, and pizza boxes. Heating nonstick surfaces above 260C (500F) causes faster breakdown.
