The chemical Bisphenol A (BPA), which is used in such household plastic products as baby bottles and food containers, has been linked to various health conditions. These conditions include breast cancer, prostate cancer, infertility, obesity, and attention deficit hyperactivity disorder (ADHD), among others.
According to a feature on the Los Angeles Times, a study released by the Breast Cancer Fund and the breast cancer research group Silent Spring Institute has found that simple changes in one’s diet can significantly reduce a person’s exposure to BPA.
The study, “Food Packaging and Bisphenol A,” monitored five Bay Area families over an 8-day period, in January 2010. Urine samples were collected from family members, after each member has had a normal meal. Participating families were all composed of four members: an adult male, an adult female, and two children between the ages of 3 and 11.
Each of the participating families ate meals that were prepared outside of the home. These meals included canned food, canned soda, and frozen dinners. They also microwaved food in plastic containers.
For a 3-day period during the study, the families were then asked to follow a modified diet, which consisted of organic meals and snacks. A caterer prepared and delivered meals that did not use foods that came packaged in cans or plastics, and the meals were stored in glass and stainless steel containers.
Breast cancer fund science advisor, and director of the Program in Science, Technology and Society at Vassar College, Janet Gray, Ph. D., shared: “One of the main sources of BPA is believed to be food packaging, but there weren’t any studies that had actually looked at having people eat a normal diet and then stop eating foods that had been wrapped in BPA-containing products… We wanted to be able to ask the question: Could we have fairly simple changes in people’s lives, both adults and children, that would alter their exposure and body burden of BPA?”
Dr. Gray was a co-author of the study, which was published in the journal environmental health perspectives.
