Chemicals used in food wrappers, non-stick pan coatings and clothing may boost body weight by interfering with metabolism, especially in women, US researchers said.
These chemicals — known as perfluoroalkyl substances (PFASs) — have previously been linked with cancer, hormone disruption, immune dysfunction, high cholesterol, and obesity.
“Now, for the first time, our findings have revealed a novel pathway through which PFASs might interfere with human body weight regulation and thus contribute to the obesity epidemic,” said senior author Qi Sun, assistant professor in the Department of Nutrition at Harvard University T.H. Chan School of Public Health.
PFASs — found in non-stick pan coatings — could be leading to a boost in body weight.
“Those who gained the most weight back also had the highest blood concentrations of PFASs, and the link was strongest among women,” said the report in the journal PLOS Medicine. …
The chemicals can accumulate in drinking water, persist for a long time in the body, and are difficult to avoid.
There has to be a reason for the obesity epidemic, and some subtle change to our diet or environment is the obvious suspect. Maybe this is it, or part of the reason.
