BPA Is an Organic Compound Used to Harden Plastic
Excerpt: Exposure to hormone disrupting chemicals such as BPA, or bisphenol A, can be reduced significantly by eating fewer foods packaged in metal cans or plastic, according to a new report from the Breast Cancer Fund and the Silent Spring Institute.
"I knew, of course, that these chemicals were in food packaging, but I was surprised by the magnitude of the decrease that we saw," said Ruthann Rudel, lead author of the study and director of research at the Silent Spring Institute, a nonprofit research organization named for Rachel Carson, whose book, "Silent Spring," kicked off the modern environmental movement.
What Rudel and her colleagues found was that when fresh food -- not canned or packaged in plastic -- was given to 20 study participants over three days, the level of BPA and other chemicals in their systems dropped substantially.
On average there was 66 percent less BPA in their urine and a 53 to 56 percent decrease in the amount of DEHP, a plasticizer. When the participants returned to their normal eating habits, their levels of BPA and the DEHP compound spiked immediately.
