Do endocrine disrupters cause asthma and obesity?

According to press reports, investigators from a Mt. Sinai School of Medicine project funded by the Environmental Protection Agency (EPA), “Growing Up Healthy in East Harlem,” find higher levels of endocrine disrupters, mostly phthlates and bisphenol A, among obese girls (age six to eight) in East Harlem, as compared to girls who are not obese.   The actual research does not appear to be published yet – I can’t find it on the Epidemiology website – but the EPA’s site provides the latest report on the project.

Endocrine disrupters are widely used in food and beverage packaging materials, as well as things such as cosmetics, shampoos, lubricants, and paint. As I explained in earlier posts, federal agencies have been taking a hard look at such substances, particularly bisphenol A.  Their interim conclusion: such chemicals pose no harm at current levels of intake.

While waiting for more research or regulatory action, a group called As You Sow has asked food companies what they are doing about bisphenol A.  Its report, Seeking Safer Packaging, concludes that the companies it surveyed generally aren’t doing nearly enough.  A few companies – notably Hain Celestial, Heinz, and Nestle (no relation) do have plans to phase out these chemicals eventually.

Why isn’t there more research on endocrine disrupter chemicals?  Without it, we have only two choices: precaution or do nothing and see what happens.  In this instance, it looks like the evidence favors precaution.  Glass bottles, everybody!
