A CHEMICAL RED FLAG
Regarding "How Packaged Food Makes Girls Hyper," by Aimee Cunningham [Head Lines], it is possible that a high level of BPA in the mother is a symptom of a different underlying problem, rather than the cause of the behavioral issues in young children.

The sources of BPA in humans are commonly packaging from processed foods and beverages that may themselves contain many other additives. High BPA levels probably correlate with poor diet and nutrition, as well as with higher levels of caffeine, artificial sweeteners, colors and flavors, all of which some studies link causally with behavioral problems in children.
