BPA and your health: should you worry?

Bisphenol A — the banned-from-baby-bottles chemical found in food-can linings, some plastic containers, paper receipts and in the bodies of 95 percent of adults and kids in North America — is in the news again. This time, just as the U.S. Food and Drug Administration declared that BPA levels in food were safe, an important new study says the chemical can boost blood pressure. That doesn’t mean you should panic.

A growing stack of human studies highlights associations between BPA exposure and risk for fertility problems, diabetes, heart disease, high blood pressure, liver and kidney problems, obesity and inflammation. These studies can’t conclude that BPA causes these problems. But one new study from Seoul National University College of Medicine in South Korea draws a more direct connection. When volunteers drank two servings of soymilk from cans lined with a BPA-containing epoxy, their blood pressure increased an average of five points. BP didn’t go up when volunteers drank soymilk from glass bottles.

At the heart of the BPA controversy: A roiling scientific debate over whether our exposure levels are safe or too high. We’ll know more when a major, government-funded study ends in a few years. For now, these steps can help you sidestep BPA:

Eat fresh. Packaged food is the biggest source of BPA exposure for most people. Skip foods sold in plastic containers that have the number 3 or 7 printed in the triangular recycling symbol on the bottom of the package. Some of these may contain BPA, says the National Institute of Environmental Health Sciences, part of the National Institutes of Health.

It makes a difference. In one study, people who had canned soup every day for five days had urine levels of BPA 1,000-fold higher than those who ate soup made from fresh ingredients. In another, families that ate fresh foods (they didn’t eat out, stopped microwaving in plastic and didn’t munch canned foods or edibles from containers containing BPA) for three days reduced levels of BPA in their urine by 66 percent.

Go for more veggies, and less meat, too. According to the European Food Safety Authority (the European Union equivalent of the U.S. FDA), meat is also a source of BPA, perhaps through contact with plastic in packaging or during processing.

Skip canned drinks. BPA is in the epoxy linings of drink cans, too. Another reason to think twice before you pop the top.

Store and reheat like this: Use stainless steel, glass or ceramic containers to store food, rather than plastic. (Look for BPA-free lids, too.) Microwave in glass containers rather than plastic.

Say “yes” to email receipts, “no, thanks” to paper. We love the fact that more and more stores send email receipts for in-person purchases. They’re keeping one widespread source of BPA, thermal paper, out of your hands.
