Excerpt: "A common class of chemicals that’s been linked to cancer, fertility problems, and thyroid dysfunction has now been tied to another major health issue: According to a new study in PLOS Medicine, women who have high levels of perfluoroalkyl substances (PFAS) in their blood tend to gain back more unwanted weight after dieting.

The new study included both men and women who’d been enrolled in a two-year clinical trial and who lost weight by following a heart-healthy diet. But when researchers factored in the levels of PFAS in participants’ blood at the start of the study, they found that people with high levels tended to gain more of that weight back after initially losing it. ... 

The researchers concluded that PFAS may play a role in body weight regulation, and therefore in the country’s current obesity epidemic. “We all know it’s feasible to lose weight through diet or physical activity; however the challenging part is that almost no one can maintain that weight loss,” says senior study Qi Sun, assistant professor in the department of nutrition at Harvard T.H. Chan School of Public Health. “Now we’ve shown that PFAS level may actually determine how much weight people regain.” ...

Previous studies have found that PFAS have the potential to leach into food—and that once PFAS enter the body, they stay there for years. That’s reason enough to avoid exposure whenever possible, says Laurel Schaider, PhD, an environmental chemist at the Silent Spring Institute and lead author of the food-wrapper study.

“I think we all already have some reasons to reduce how much fast food we consume, and this may be another one,” Schaider told Health in 2017. “If you’re going to eat it, you could try to get the food out of the wrapper as quickly as possible—that might help a little bit."'
