Is there good evidence that BPA is harmful to human health?

By Susan Brewer, Ph.D., University of Illinois,

The National Institute of Environmental Health Sciences (U.S. Department of Health and Human Services) recently declared that it has some concern over the chemical's effect on fetuses, infants, and children. The concern comes from laboratory animal studies which concluded that exposure to BPA during development could cause changes in behavior and the brain, prostate gland, mammary gland, and the age at which females attain puberty. One specific concern was that exposure to BPA increased prostate cancer. However, based on prostate screening testing (PSA), this appears not to be the case. Based on scientific studies, regulatory agencies have found insufficient evidence that the low doses to which humans are exposed pose a health concern.
