    PFAS (Per- and Polyfluoroalkyl Substances)- A family of 10,000+ synthetic chemicals with an unbreakable carbon-fluorine bond. Found in nonstick cookware, air fryer baskets, food packaging, and drinking water. Called "forever chemicals" because they accumulate in the body and never break down — with links to cancer, immune suppression, and hormone disruption.
