Eating Fresh Foods May Cut Exposure to BPA

Study: Avoiding Packaged, Canned Foods May Reduce Levels of the Chemical Bisphenol A

Avoiding Sources of BPA continued...

Participating families gave up water in plastic bottles in favor of stainless steel.

Eating out was also avoided since other studies have shown some restaurant meals to be high in BPA.

By the end of the study, urine tests showed the average BPA level dropped 66%, from 3.7 nanograms per milliliter (ng/mL) to 1.2 ng/mL. Levels of DEHP metabolites dropped by about half, from 57 ng/mL to 25 ng/ML.

People who started the study with the highest BPA levels saw even bigger reductions -- 76% for BPA and about 95% for DEHP metabolites.

“Especially after finding out the results, we have completely eliminated the plastics and the canned food,” Laurland says. “It’s really very simple things, and overall, those things are healthier for you anyway.”

“What sold me on it is that I can easily take that toxic chemical out of my body and I don’t have to worry about it,” she says.

Why Worry About BPA?

Participants saw their levels drop, but science still doesn’t know whether or not that matters.

“What the question is, is exactly how much risk, and to whom, from this kind of exposure? We’re at a point where that’s still emerging,” Rudel says.

Still, the existing science has been compelling enough for Canada, which banned the use of BPA in baby bottles in 2008.

In the U.S., Eden Organic has started to sell foods in BPA-free cans. Several states have acted to limit the use of BPA, and similar bills are pending around the country.

The FDA is still studying that question, but so far, says that there’s no need for families to change how they eat.

The food industry supports that statement.

“We agree with the U.S. Food and Drug Administration (FDA) that foods packaged in cans with epoxy linings that utilize BPA are safe, and that there is no need for consumers to change their consumption habits,” the Grocery Manufacturers Association says in a statement. “That position is supported by the findings of numerous food safety agencies around the globe, such as the European Food Safety Authority (EFSA) in the EU, Germany, Japan, UK, Canada, and Australia-New Zealand, which have all repeatedly confirmed the safety of BPA and continue to reaffirm the safety of BPA, including at levels comparable to those found in the exposure survey published in EHP.”

What Studies Show

Animal studies have shown an association with high and low levels of BPA with problems in neurodevelopment and reproductive development.

In 2008, the Journal of the American Medical Association published a study that found that adults with the highest levels of BPA in the study had more than twice the risk of getting diabetes as adults with the lowest levels.
