They have to do with receipts, microwaves, and more.
The science:
Researchers have discovered a more accurate way to measure BPA in the human body. Their results show that levels are about 44 times higher than previously reported.
Expert insight:
BPA exposure can interfere with your hormones, metabolism, fertility, cancer risk, and more, says study author Patricia Hunt, Ph.D., professor of molecular biosciences at Washington State University in Pullman.
A few minor changes can dramatically reduce your BPA exposure, she says. First, never put plastic of any kind in the microwave or dishwasher. Second, replace Tupperware as soon as it shows wear and tear, a sign that it’s leaching chemicals. Third, request digital receipts (or none at all) over printed ones, which are a big source of BPA.
The bottom line:
It’s impossible to avoid all BPA, Hunt says, but following the above rules will help minimize your risks.
