Study Finds How BPA Affects Gene Expression, Anxiety; Soy Mitigates Effects
Release Date: 09.07.2012
New research led by researchers at North Carolina State University
shows that exposure to the chemical bisphenol A (BPA) early in life
results in high levels of anxiety by causing significant gene expression
changes in a specific region of the brain called the amygdala. The
researchers also found that a soy-rich diet can mitigate these effects.
“We knew that BPA could cause anxiety in a variety of species, and
wanted to begin to understand why and how that happens,” says Dr.
Heather Patisaul, an associate professor of biology at NC State and lead
author of a paper describing the work. BPA is a chemical used in a wide
variety of polycarbonate plastics and epoxy resins, and is used in
consumer products such as some food containers.
