UCLA Health reporting:

Studies have linked PFAS to adverse health effects, including high blood pressure, decreased fertility in women, liver damage, cancer, low birthweight and an increased risk of asthma and thyroid disease.

Research suggests that people who regularly consume microwave popcorn have markedly higher levels of PFAS in their bodies. A study published in 2019 analyzed a decade of data about the eating habits of 10,000 people, which was collected by the Centers for Disease Control and Prevention between 2003 and 2014. Blood samples from the study participants were also collected. The researchers found that people who ate microwave popcorn every day over the course of a year had levels of PFAS that were up to 63% higher than average.

Considering the questions that continue to surround the safety of consuming PFAS, we think it would be reasonable to curtail the daily use of microwave popcorn. Instead, you could save it for an occasional treat. If your kids are flexible, you might switch to a different type of evening snack. Or if it has to be popcorn, you could turn the process of making stovetop popcorn into a family project.

So much for movie night popcorn.
