Letter: The weight of the scientific evidence on BPA shows it is not a health risk

The recent column by Drs. Mehmet Oz and Michael Roizen ("Get the science behind BPA's risk to your health," March 31) continues to misrepresent the science showing bisphenol A’s (BPA) safety and needlessly scares consumers about the safety of everyday products.

BPA is one of the most studied environmental chemicals ever with nearly 9,000 PubMed citations. Oz and Roizen simply cherry-pick a handful of studies showing possible associations between BPA and health problems — the opposite of the extensive literature reviews performed by the European Food Safety Authority and U.S. Food and Drug Administration.

Contrary to the claim made in the doctors’ column, EFSA and the FDA did take into account recent research of low-dose exposure to BPA and a range of health effects. EFSA, in particular, considered studies of general toxicity, reproductive and developmental effects, neurological effects, immune effects, cardiovascular effects, metabolic effects, carcinogenicity and found that when they considered the weight of the evidence, “BPA poses no health risk to consumers of any age group.”

Oz and Roizen brazenly claim BPA can “mess with your metabolism and lead to weight gain,” but while some short-term studies in rats have linked BPA to weight changes, EFSA notes “there is no convincing evidence that BPA is obesogenic [obesity-causing] after intrauterine exposure or in longer-term studies.”

It’s, in fact, Oz and Roizen who aren’t listening to the weight of scientific evidence; it’s troubling they’re instructing their vast readership to follow suit.
