PFAS is in so many common consumer products you might well say "it is in everything." That outdoor jacket you're wearing? Coated in PFAS. Your stain-resistant couch? PFAS.

All textiles break and release fibres, and we inevitably end up eating them.

And if you are cooking with a non-stick pan, it is a guarantee that you are ingesting them. It doesn't have to be the PTFE itself, the emulsifiers (such as PFOA https://en.wikipedia.org/wiki/Perfluorooctanoic_acid) are more volatile and have been measured in food cooked with non-stick pans.

> There is general agreement that dietary intake is the largest source of PFAS exposure rather than inhalation or dermal contact [...] For PFOA, EFSA suggested the most important sources of chronic exposure were milk and dairy products for toddlers (up to 86% of exposure), drinking water (up to 60% for infants), and fish and other seafood (up to 56% in elderly).

> There really is a very minimal amount of residual PFOA or other perfluorinated chemicals in the nonstick pans — like, you know, thousands of folds lower than what is observed in the water or food. -- Dr. Mimi Huang, NIH
