Microwaveable Popcorn
In the late 2010s, article headlines announced that popcorn could cause cancer. While nothing inside popcorn poses a cancer risk, the lining inside the microwavable bag does. Research in 2013 found that these bags contain perfluorooctanoic acid (PFOA), a chemical that encouraged pancreatic, testicular, and liver cancer in animal studies.
But will eating the popcorn spread PFOA? According to a 2019 study in Environmental Health Perspectives, participants who ate this popcorn had PFOA in their blood. It can remain there for three to five years. To avoid the chemical, cook homemade popcorn.
