DevotedSkeptic sends this excerpt about research that found a correlation between the use of a common food-packaging chemical and obesity rates. "Since the 1960s, manufacturers have widely used the chemical bisphenol-A (BPA) in plastics and food packaging. Only recently, though, have scientists begun thoroughly looking into how the compound might affect human health—and what they've found has been a cause for concern. Starting in 2006, a series of studies, mostly in mice, indicated that the chemical might act as an endocrine disruptor (by mimicking the hormone estrogen), cause problems during development and potentially affect the reproductive system, reducing fertility. After a 2010 Food and Drug Administration report warned that the compound could pose an especially hazardous risk for fetuses, infants and young children, BPA-free water bottles and food containers started flying off the shelves. In July, the FDA banned the use of BPA in baby bottles and sippy cups, but the chemical is still present in aluminum cans, containers of baby formula and other packaging materials. Now comes another piece of data on a potential risk from BPA but in an area of health in which it has largely been overlooked: obesity. A study by researchers from New York University, published today in the Journal of the American Medical Association, looked at a sample of nearly 3,000 children and teens across the country and found a 'significant' link between the amount of BPA in their urine and the prevalence of obesity."
