In 2006, 38 leading researchers from various disciplines evaluated more than 700 studies on BPA. Based on animal studies, they concluded that there was “great cause for concern with regard to the potential for similar adverse effects in humans.”

WHAT BPAs DO

While more research needs to be done, studies of BPA’s effects on animals conclude:

*This hormone-mimicking compound has been shown to produce precancerous changes in the mammary and prostate glands.

*It prompted the onset of early puberty.

*Two studies showed that human adults with the highest levels of BPA had a higher incidence of heart problems.

*The Natural Resources Defense Council's reports of animal studies and BPA that resulted in reproductive abnormalities like a lower sperm count and abnormalities in the number of chromosomes in eggs.

*BPA caused obesity and insulin resistance that may lead to the development of diabetes. The Natural Resources Defense Council concludes that the vast majority of Americans have levels of BPA in their bodies at levels close to those causing serious disruption in animals.

*A French study in 2011 found that BPA in low doses can change tooth enamel, causing it to be brittle.

*Reproductive results of BPA studies are especially alarming. In 2014 Chinese researchers found that BPA exposure led to lower testosterone levels, which can be correlated with a low sex drive. Scientists at Washington State University in 2014 found that tiny doses of BPA could permanently disrupt the body’s ability to produce high-quality semen.
