New study reveals diet link to PFAS ‘forever chemicals’ in human body

US research shows foods such as butter and processed meat likely to increase levels of toxic PFAS in blood over time

Diets rich in foods such as processed meat and butter likely increase levels of toxic PFAS “forever chemicals” in human blood over time, new peer-reviewed research has found.

The paper identified a range of foods to be among the drivers of high PFAS levels, including teas, pork, candy, sports drinks, processed meat, butter, chips and bottled water. The research also pointed to higher PFAS blood levels among those who consumed more carryout or food prepared at restaurants.
