BPA Messes With Your Hormones ‚ÄĒ and It's in These Canned Foods
J Thoendell stashed this in Food
Heads up, canned-food eaters: A¬†report¬†released today by the Environmental Working Group details which canned food brands use bisphenol A (BPA) in the lining, and which don't.
Most of us know BPA as the plastic additive that mimics the hormone estrogen and has been removed from things like¬†water bottles¬†and¬†baby formula¬†packaging. But BPA lines an estimated¬†75 percent¬†of canned foods in North America,¬†protectingthe metal from corroding and preventing bacteria from getting in. This has environmental advocates concerned, because the chemical leaches into the contents of cans at far¬†higher rates¬†than it does into, say, the water in your water bottle.
A 2011 Harvard¬†study¬†found that those who ate canned soup every day for five days had levels of BPA in their urine that were ten times those who had fresh soup. Another¬†study¬†from the same year found BPA in 71 out of 78 canned food samples, with concentrations varying drastically between food types and even within the same product. The Food and Drug Administration¬†maintains¬†that BPA is "safe at the current levels occurring in foods," though¬†scientists¬†have linked low-dose, long-term exposure of the chemical to to breast cancer, changes in the reproductive system, and other health problems.
