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.
