BPA Linked to Obesity in Adolescent Girls
Yet another study has concluded that the common plastic chemical, bis-phenol A (BPA), is causing health problems around the world. BPA is a known “endocrine disruptor,” and it is found circulating in the bloodstreams of virtually everyone on the planet. And no wonder: more than six billion pounds of the stuff are produced every year. High exposure has previously been linked to a higher risk of diabetes and cardiovascular disease.
BPA behaves like estrogen in the body, and has been linked to reduced testosterone levels in men and male sexual dysfunction, including dysfunctional sperm. The chemical has also been linked to low birthweight babies. Now scientists have concluded that prepubertal girls with the highest concentrations of the chemicals in their bloodstreams are five time more likely to be overweight or obese compared to girls of the same age with the lowest levels of the widely distributed chemicals.
The study ruled out other factors, such as dietary patterns, physical activity and family history. “Our study suggests that BPA could be a potential new environmental obesogen, a chemical compound that can disrupt the normal development and balance of lipid metabolism, which can lead to obesity,” Dr. Li and co-authors wrote. “Worldwide exposure to BPA in the human population may be contributing to the worldwide obesity epidemic.”
In my book, “True Nutrition-European Secrets for American Women,” I discuss various strategies for reducing your exposure to these problematic chemicals.
