DEAR DOCTORS: I’ve been hearing a lot about PFAS and how they have an adverse effect on our health. I read that some food wrappers, like bags for microwave popcorn, use PFAS to keep food from sticking. My kids eat microwaved popcorn almost every night. Should I be worried?
DEAR READER: The term PFAS refers to a large group of manmade chemicals known as perfluoroalkyls and polyfluoroalkyl substances. Previously known as PFCs, or perfluorochemicals, they were developed in the 1950s.
