5 Ways to Reduce Your Exposure to Toxic BPA

By Monica Amarelo and Samara Geller

No one disputes that bisphenol A, a toxic compound widely used to line food cans and other food packaging, is polluting people. The Centers for Disease Control and Prevention found BPA in the urine of more than 90 percent of Americans sampled. In 2009, tests commissioned by the Environmental Working Group (EWG) were the first to find BPA in the umbilical cords of nine of 10 infants sampled.


Because food packaging is the primary source of exposure, it stands to reason that BPA levels in our bodies are affected by what we eat and how that food is packaged. Although a new British study suggests that lowering your BPA level yourself through diet is not easy, there are some steps you can take to reduce your exposure.

BPA acts like estrogen in the body. It disrupts hormones, affects brain development and metabolism, and harms the reproductive system. Evidence suggests the developing fetus and young child are most at risk, but adolescents also appear uniquely vulnerable. BPA has also been linked to cancer, heart disease and other serious disorders.

The new study, by researchers at the University of Exeter and published in the journal BMJ Open, was the largest real-world study to date of the effect of dietary moderation on BPA in the body. It tracked 94 teenagers who for one week changed their eating habits and behaviors to try to avoid BPA in food packaging. While the researchers found no measurable effect on BPA levels in the overall group, they did see a reduction in BPA levels for the teens who started the trial with the highest levels.

Researchers speculated that the drop in BPA levels would have been more significant in a controlled setting. But the teenagers were going about their normal lives, and they reported it was hard to know what they could eat because BPA is so widely used and packaging containing BPA is so poorly labeled.

In 2012 the U.S. Food and Drug Administration banned BPA in baby bottles and sippy cups. A year later, the agency prohibited it in infant formula packaging. But, like the British teens, for the rest of us avoiding BPA is still a challenge.

In 2016, EWG created a database of about 16,000 processed foods and drinks that might be packaged in materials that contain BPA. In California, products packaged in materials with BPA must carry a warning label on the package or store shelves.

As the food industry scrambles to find alternatives to BPA, concern has grown that without appropriate oversight, food companies will substitute similar chemicals or new chemicals that could be just as harmful or even more harmful. A National Toxicology Program study of 24 replacement chemicals found that many already in use are structurally and functionally similar to BPA, and, just like BPA, may harm the endocrine system.

Here's what you can do to limit or avoid exposure to BPA:

1. Buy fresh, frozen or dried food instead of canned.

2. Limit how many packaged foods you eat.

3. For those who cannot avoid foods in BPA-lined cans, rinsing the food in water may help lower the level of BPA in the food. Bonus: Rinsing cuts back on other additives too, such as sodium on beans or sweet syrup on fruit.

4. Never heat food in the can. Transfer it to a stainless steel pot or pan for stovetop cooking or microwave in glass—not plastic.

5. Search for your family's favorite foods and beverages in EWG's BPA product list. If they are packaged in containers made with BPA, look for alternative products in EWG's Food Scores. Tip: Use the BPA-free filter function when searching.

India Suffers 'Worst Water Crisis in Its History'

India is facing its "worst-ever" water crisis, according to a report from a government think tank issued last week.

Around 200,000 Indians die each year due to lack of water access, the report finds, and demand will be twice as much as supply by 2030.

Urban Gardening 101: How to Deal With Contaminated Soil

By Brian Barth

Urban soils are particularly prone to contamination. Fifty years ago, your yard could have belonged to a farmer, who, perhaps not knowing any better, disposed of old bottles of anti-freeze or contaminated diesel in a hole out behind the tractor garage. Or perhaps the remains of a fallen down outbuilding, long ago coated in lead-based paint, was buried on your property buy a lazy contractor when your subdivision was built.

Sea Level Rise Could Put 2.4 MIllion U.S. Coastal Homes at Risk

More than 300,000 U.S. coastal homes could be uninhabitable due to sea level rise by 2045 if no meaningful action is taken to combat climate change, a Union of Concerned Scientists (UCS) study published Monday found.

The study, Underwater: Rising Seas, Chronic Floods and the Implications for U.S. Coastal Real Estate, set out to calculate how many coastal properties in the lower 48 states would suffer from "chronic inundation," non-storm flooding that occurs 26 times a year or more, under different climate change scenarios.

U.S. Sees Steady Solar Growth Despite Trump, But China Slashes Subsidies

By Andy Rowell

Donald Trump can't stop the sun from shining. Despite the climate denier's pro-fossil fuel agenda, and despite his tariffs on imported solar panels, the U.S. still installed more solar than any other source of energy in the first quarter of the year.

The amount of solar power installed in the U.S. climbed 13 percent in the first quarter, according to the trade body, the Solar Energy Industries Association (SEIA).

How a Minor Change to EPA Rules Could Slash Environmental Protection

By Joseph Aldy

Since the Reagan administration, federal agencies have been required to produce cost-benefit analyses of their major regulations. These assessments are designed to ensure that regulators are pursuing actions that make society better off.

In my experience working on the White House economic team in the Clinton and Obama administrations, I found cost-benefit analysis provides a solid foundation for understanding the impacts of regulatory proposals. It also generates thoughtful discussion of ways to design rules to maximize net benefits to the public.
