The mice that were directly exposed to BPA in the womb were less social and more isolated than the other group. They spent less time exploring their cages and engaging with other mice. But by the third generation, the behavior had flipped. The BPA-exposed mice were more social and engaged than the other mice. While that may sound like a good thing, it isn’t. It simply means that the chemical continues to influence brain activity for generations, the authors wrote in their study.
In fact, some of the behavioral issues they saw in all generations of mice were similar to those seen in autistic children and children with attention-deficit hyperactivity disorder. “Autism is characterized by a reduction in social interactions and we observed some declines in social interaction in the BPA-exposed mice,” says Emilie F. Rissman, the study’s lead investigator and a professor of biochemistry and molecular genetics at the University of Virginia School of Medicine.
3 surprising tips to avoid BPA:
• Ditch canned food. Cans are lined with an epoxy resin that’s made with BPA, and that includes things like soup, canned beans, and soda. Look for aseptic cartons, glass jars, and frozen foods as alternatives. OR MAKE YOUR OWN (Pumpkin puree, for example)
• Decline receipts. They’re coated with a BPA-based coating that rubs off onto your fingers and whatever else it comes in contact with.
• Be wary of dental sealant
