A study published in the Journal of the American Medical Association shows that children with higher levels of BPA in their bodies are more likely to be obese. Liz Szabo at USA Today notes that it is “the first large-scale, nationally representative study to link an environmental chemical with obesity in children and teens.” Doesn’t mean BPA (bisphenol A) *caused* the obesity, but the association is interesting—particularly given the growing body of research linking BPA and cancer.
