Unsettling stories about Bisphenol-A are accumulating in my browser even faster than BPA itself is piling up in my blood. Or wherever it works its terrible, epidemiologically studied magic.
First up, Mark Schapiro, of the Center for Investigative Reporting, was on Fresh Air a couple of weeks ago. He talked about his new book, Exposed: The Toxic Chemistry of Everyday Products, and What's at Stake for American Power. Even though he's from Berkeley, he's a happy smoker, not one of those hemp shoe types, so what he says about the US safety and scientific standards slipping behind the EU--and even China--must be true. Turns out it's not the little differences after all.
And if that doesn't knock you off your natural latex yoga ball, try this survey/study by the Environmental Working Group in Mothering Magazine on the presence of significant-to-alarming levels of BPA in infant formula: "all manufacturers use BPA to line the metal portions of all infant formula containers, including powdered varieties."
Actually, the powder thing is sort of a red herring; the real issue with BPA is leaching, and liquid formula that sits around on a shelf has nothing else to do but leach. The powdered kind doesn't act the same way, plus, mixing it with water reduces the BPA levels.
But is it a big deal?
EWG has found that one out of every 16 infants fed ready-to-eat liquid formula are exposed to BPA at doses exceeding those that caused increased aggression and significant changes in testosterone levels in laboratory animals.Hmm, whatever the glassniks say, I can imagine at least a few people who would see aggression and testosterone-boosting as product features, not bugs. Look for liquid formula to be added to the training regimen of Ultimate Fighting fan kids almost immediately.
