Food preservative promotes overeating
A popular food preservative in mass-market cereals and other packaged foods, BHT (short for butylhydroxytoluene) stimulates overeating, according to research at Cedars-Sinai Medical Center in Los Angeles. PFOA (perfluorooctanoic acid), found in some nonstick cookware, carpeting, and cleaning products, and TBT (tributyltin) in paints, which can end up in water and seafood, had a similar effect. “We discovered that each of these chemicals damaged hormones that communicate between the gut and the brain,” said researcher Dhruv Sareen, PhD. The toxins shut off signals that indicate we’ve eaten enough, resulting in overeating and weight gain. Among the three chemicals tested, BHT was the worst offender.
