Even BPA-Free Plastics Might Not Be Safe, Which Is More Than A Little Terrifying
You already knew that plastics containing BPA might be bad for you — but, as it turns out, even BPA-free plastics may not be safe. A damning report in the latest issue of Mother Jones has drawn attention to 2011 research that found various types of plastics, including the BPA-free variety, could possibly impact your health in much the same way as the highly-publicized chemical — and in some cases, be even worse.
Published in the journal Environmental Health Perspectives , a team led by CertiChem Inc. researcher George Bittman placed a range of different plastics under stress of UV radiation and microwaving, and monitored their effect on human breast cancer cells — which can multiply rapidly in reaction to estrogen. The primary issue with BPA is that the chemical has been shown to possibly function as a synthetic estrogen, and has been linked to various medical problems that include obesity, cancer, and diabetes.
But dodging BPA-free plastics doesn't mean you're necessarily avoiding exposure to synthetic estrogen. According to Bittman's study:
Concerns about BPA plastics have spiked in the last few years, and many plastics now market themselves as "BPA-free." The Eastman Chemical Co. sells a plastic called Tritan, which is marketed on the strength of being "EA-free" — that is, not just free of BPA itself, but free of "estrogenic activity."
Unfortunately, according to the Mother Jones findings, the Tritan ingredient, triphenyl phosphate (or TTP,) was shown to be even more estrogenic than BPA.
Eastman Chemical had sold Tritan as not just non-BPA, but free of estrogenic activity altogether. This, according to Bittman's research and that of Eastman rival PlastiPure, is untrue. So the allegation becomes one not just one of health, but of knowingly fraudulent marketing to boot. The Mother Jones feature outlines Eastman's efforts to mitigate the controversy, including the hiring of consultants and scientists who acted on behalf of Big Tobacco.
Still, it's important to remember that the level of concern we should have about BPA itself isn't yet clear. Sparse studies, often performed on rats, have fueled an impassioned battle between health activists and industry advocates. As Bustle reported:
