Study Says BPA-Free Plastics Are Just As Harmful to Health

Plastic products that boast of being “BPA-free” aren’t necessarily any safer for us, suggests a new mouse study published Thursday in Current Biology. The chemicals used to replace BPA in these plastics can still leak out and affect the sperm and eggs of both male and female mice, it found. And these same effects could be happening in people.

Bisphenol A, or BPA, is a chemical commonly used to create polycarbonate plastics and epoxy resins. These clear white plastics are themselves used in food and drink packaging, as well as consumer products and medical devices, while resins are used to coat metal products like canned foods. When these products degrade or are otherwise damaged (from being repeatedly heated in a microwave, for example), they can leach out BPA, exposing us to it. As a result, it’s estimated that 93 percent of Americans have some level of BPA in their system.
