Want to reduce BPA exposure? Cut canned foods

KTXL: "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," said Janet Gray, Ph.D., director of the Program in Science, Technology and Society at Vassar College and science advisor to the Breast Cancer Fund.

Gray co-authored "Food Packaging and Bisphenol A," a peer-reviewed study published in the journal Environmental Health Perspectives.

"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?" Gray said.

Switching to fresh foods decreased BPA levels very quickly.

"That's one of the most important findings of this study."
