Food contaminants worsen metabolic problems in obese mice

 "Certain food contaminants are suspected of triggering metabolic disorders, or of worsening them, particularly when they accompany a high-fat diet. In order to get a better understanding of these effects, researchers from the Inserm cardiovascular, metabolism, diabetology and nutrition unit (U1060 " Laboratoire de recherche en cardiovasculaire, métabolisme, diabétologie et nutrition " Inserm/Inra/Université Lyon 1) introduced a "cocktail" of contaminants mixed with low doses of dioxin, PCB, bisphenol A and phtalates into the feeding of mice that had already been rendered obese by a high-fat diet. The results show that metabolic changes occur in these mice, but that the effects differ depending on the gender. Females appeared to be more affected. Their obesity-induced glucose intolerance worsened and their estrogen pathway was altered."
