Myth What about the viral claim? Is non-stick cookware safe? What changed, and what hasn’t 

Why make the swap

  • Why switch to cast iron or stainless steel pan

    Cast iron, carbon steel or stainless steel. There’s no coating to wear off, and a well-made pan can last for decades.

  • What's the concern with non-stick pan

    PTFE, sold under brand names such as Teflon™, is a PFAS, and FDA says some PFAS are approved for making non-stick cookware coatings. PFOA, once used to make it, is classed by IARC as carcinogenic to humans, but today’s pans are PFOA-free. The risks now are fumes from overheated empty pans, flaking from scratched coatings, and PFAS released when the pans are made.

  • General information, not medical advice. Ask your doctor, especially if you’re pregnant, nursing or have a health condition.

  • Good to know before you buy

    Cast iron is heavy; it and carbon steel need seasoning. Stainless needs none and suits tomato and other acidic dishes. Ceramic ‘non-stick’ is still a coating, not bare metal.

Questions people ask

Is Teflon a PFAS?

Yes, PTFE, the non-stick coating sold under brand names such as Teflon™, is a PFAS. Today’s pans are made without PFOA, the PFAS once used to make it, which IARC classes as a carcinogen. More on choosing pans: our non-toxic cookware guide.

Does cast iron need seasoning?

Yes, cast iron and carbon steel need seasoning, and cast iron is heavy. Stainless steel needs none and suits tomato and other acidic dishes.

Is ceramic non-stick the same as bare metal?

No. Ceramic ‘non-stick’ is still a coating, with two lab studies behind it so far; our non-toxic cookware guide explains them. Cast iron, carbon steel and stainless steel have no coating to wear off.
