Nonstick cookware coated with PTFE (Teflon) or PFAS-based coatings releases toxic fumes when overheated and sheds coating particles into food as the coating degrades. PFAS are 'forever chemicals' that accumulate in the body and are associated with cancer, thyroid disease, and immune system disruption. Cast iron, stainless steel, and carbon steel are the safe, durable alternatives.
Why We Rated It This Way
Calphalon's nonstick cookware uses PTFE coating — which releases toxic fumes when overheated and degrades over time. A complete stainless steel or cast iron cookware set is a permanent, safe replacement.
