Non-Stick Pan Coatings Linked to Thyroid and Liver Disruption

PFAS chemicals used in Teflon and similar non-stick coatings have been found to persist in the human body for years, with studies linking them to thyroid disease, liver damage, and immune suppression.
Per- and polyfluoroalkyl substances (PFAS) — the chemicals that give non-stick cookware its slippery surface — have come under intense scientific scrutiny. Often called "forever chemicals," PFAS do not break down in the environment or in the human body.
A comprehensive review published in the journal *Lancet Diabetes & Endocrinology* analyzed over 200 studies on PFAS exposure. Key findings include:
- Thyroid disruption: PFAS exposure is associated with hypothyroidism and altered thyroid hormone levels, even at low concentrations.
- Liver damage: Elevated liver enzymes and non-alcoholic fatty liver disease have been linked to PFAS accumulation.
- Immune suppression: Children with higher PFAS levels showed reduced antibody response to vaccines.
- Cancer risk: PFAS are associated with kidney and testicular cancers.
The primary exposure route from cookware is through overheating. When Teflon-coated pans are heated above 260°C (500°F), they begin to release PFAS fumes. At 360°C (680°F), the coating starts to decompose rapidly.
- Cast iron cookware (naturally non-stick when seasoned)
- Stainless steel
- Ceramic-coated pans (ensure they are PFAS-free — check the label)
- Carbon steel
