Can PFAS from nonstick pans and food wrappers increase diabetes risk if you have prediabetes?
Yes. Adults with prediabetes who had higher PFAS levels were more likely to develop cardiovascular disease and full diabetes.
What's actually in it
PFAS chemicals from nonstick cookware, grease-proof food packaging, stain-resistant textiles, and contaminated water accumulate in your blood over time. People with prediabetes already have impaired metabolism. Adding PFAS to the mix creates extra stress on the same metabolic pathways that are already struggling.
About 1 in 3 American adults has prediabetes. Most don't know it.
What the research says
A 2026 study in J Am Heart Assoc followed adults with prediabetes and measured their PFAS levels. Those with higher PFAS blood concentrations were more likely to develop cardiovascular disease and progress from prediabetes to full type 2 diabetes.
PFAS appear to worsen insulin resistance, lipid metabolism, and vascular inflammation in people whose metabolic systems are already compromised. The chemicals essentially push borderline systems over the edge into disease.
For anyone with prediabetes or metabolic risk factors, reducing PFAS exposure is especially urgent. Switching away from nonstick cookware, avoiding fast food packaging, and filtering tap water for PFAS are practical steps that complement dietary and lifestyle changes for blood sugar control.
