An article in the journal Environmental Health Perspectives found that people who ate more food at home averaged lower blood serum concentrations of PFAS (or”forever”) chemicals, and those who ate out more, including at fast-food and pizza restaurants, averaged slightly higher concentrations. The researchers speculated that this was due to the widespread presence of PFAS chemicals in food packaging.
The Silent Spring Institute, a Massachusetts-based nonprofit research organization, is among those investigating PFAS.7,8,9,10. A 2017 study led by Silent Spring research scientist Laurel Schaider found grease-proof PFAS coatings on 46% of food-contact papers (such as hamburger wrappers) and 20% of paperboard samples (such as french fry boxes) collected from fast food restaurants throughout the United States.11 In the new EHP report, Schaider and colleagues from Silent Spring estimated associations between blood serum levels of five common PFAS (PFOA, PFOS, perfluorononanoic acid, perfluorodecanoic acid, and perfluorohexanesulfonic acid) and consumption of fast food, pizza, and microwave popcorn.2
