Wednesday, Aug. 31, 2022 (HealthDay News) — Chewing a handful of microwave popcorn may be perfect for movie night, but yours snack Experts warn of potentially harmful “permanent chemicals” in your body.
Many microwave popcorn bags are lined PFOS (perfluoroalkyl and polyfluoroalkyl substances), there is some evidence that these chemicals can leach into the snack during the popping process.
The study found that “people who regularly eat microwave popcorn have high levels of these compounds in their blood, so it does get into the bloodstream,” said Dr. David Herb, founding director of the UCLA Center for Human Nutrition.
PFAS compounds are called forever chemicals because they break down very slowly and accumulate in both the environment and the human body.
These chemicals are commonly found in drinking water The federal government estimates that the substance can be found in the blood of 97 percent of U.S. residents.
“Drinking water has received a lot of attention, but food is also a major source of exposure, and studies have shown that consumption of microwaved popcorn and fast food is associated with higher levels of PFAS in the body,” said senior scientist David Andrews. Nonprofit Environmental Working Group.
PFAS chemicals were first developed in the 1950s as part of a nonstick coating for pans, Heber said.
They have since been added to many consumer products including cleaning solutions, waterproofing cosmeticfirefighting foams and antifouling coatings for carpets and upholstery.
Andrews said microwave popcorn makers added PFOS to the lining of the bags to keep the oil from oozing out of the popcorn.
PFAS also helps keep the bags from burning, Heber said.
“You know that sometimes if you leave the popcorn out longer, you get charred kernels?” Herb said. “Well, it’s hot enough to burn the paper, which will keep it from catching fire in the kitchen.”
But during popping, PFOS can seep into the popcorn, making the snack one of the most notorious ways the chemical can get into the body, Andrews said.
