Nonstick Pans: Convenience vs. Potential Health Risks
Nonstick pans have been a kitchen staple for decades, prized for their ease of use and quick cleanup.
However, concerns about the safety of the chemicals used in nonstick coatings, particularly PFAS (per- and polyfluoroalkyl substances), have many home cooks questioning whether the convenience is worth the potential health risks.
PFAS: The “Forever Chemicals”
Traditional nonstick pans are coated with PTFE (polytetrafluoroethylene), commonly known by the brand name Teflon. PFAS chemicals, used in the manufacturing process of PTFE, are highly persistent in the environment and human body, earning them the nickname “forever chemicals.“
While most nonstick pans made after 2015 are PFOA-free, they may still contain other types of PFAS. Tasha Stoiber, senior scientist at the Environmental Working Group (EWG), warns that these replacement chemicals “have similar health harms and persistence in the environment.“

Potential Health Concerns
Studies have linked PFAS exposure to various health issues, including:
- Increased cholesterol levels
- Higher risk of kidney and testicular cancer
- Decreased vaccine response in children
- Changes in liver enzymes
However, A. Daniel Jones, professor of biochemistry at Michigan State University, notes that “there are no studies documenting a significant risk to health arising from use of nonstick pans.”
He points out that PFAS exposure comes from multiple sources, not just cookware.
Safe Use and Alternatives
To minimize potential risks, experts recommend:
- Avoiding high heat: At temperatures above 500°F (260°C), nonstick coatings may begin to break down and release harmful fumes.
- Replacing scratched pans: A 2022 study found that scratched nonstick pans can release microplastics and Nano plastics, potentially exposing users to harmful chemicals.
- Considering alternatives: Ceramic, enameled cast iron, and stainless steel cookware offer non-stick properties without the use of PFAS.
While the debate over the safety of nonstick pans continues, it’s clear that more research is needed to fully understand the health effects of PFAS exposure from cookware.
In the meantime, cautious consumers may opt for alternative materials or take steps to use their nonstick pans safely.
