by Nicholas D. Kristof
Your body is probably home to a chemical called bisphenol A, or BPA.
It's a synthetic estrogen that United States factories now use in everything from plastics to epoxies - to the tune of six pounds per American per year. That's a lot of estrogen.More than 92 percent of Americans have BPA in their urine, and scientists have linked it - though not conclusively - to everything from breast cancer to obesity, from attention deficit disorder to genital abnormalities in boys and girls alike.
Now it turns out it's in our food.
Consumer Reports magazine tested an array of brand-name canned foods for a report in its December issue and found BPA in almost all of them. The magazine says that relatively high levels turned up, for example, in Progresso vegetable soup, Campbell's condensed chicken noodle soup, and Del Monte Blue Lake cut green beans.
The magazine also says it found BPA in the canned liquid version of Similac Advance infant formula (but not in the powdered version) and in canned Nestlé Juicy Juice (but not in the juice boxes). The BPA in the food probably came from an interior coating used in many cans.
Should we be alarmed?The chemical industry doesn't think so. Steven Hentges of the American Chemistry Council dismissed the testing, noting that Americans absorb quantities of BPA at levels that government regulators have found to be safe. Mr. Hentges also pointed to a new study indicating that BPA exposure did not cause abnormalities in the reproductive health of rats.
But
more than 200 other studies have shown links between low doses of BPA and adverse health effects, according to the Breast Cancer Fund, which is trying to ban the chemical from food and beverage containers."The vast majority of independent scientists - those not working for industry - are concerned about early-life low-dose exposures to BPA," said Janet Gray, a Vassar College professor who is science adviser to the Breast Cancer Fund.

While the evidence isn't conclusive, it justifies precautions. In my family, we're cutting down on the use of those plastic containers that contain BPA to store or microwave food, and I'm drinking water out of a metal bottle now. In my reporting around the world, I've come to terms with the threats from warlords, bandits and tarantulas. But endocrine disrupting chemicals - they give me the willies.
