Ask the Expert: Are BPA-Free Plastics Still Toxic?

We all switched to BPA-free plastics for safety, but now they might be potentially toxic, too.

I switched to BPA-free plastics because I thought they were safer, but now I hear they’re potentially toxic, too. Is this true?

Possibly. We’re still growing the body of research on alternatives to bisphenol A (BPA), which has been linked to hormone disruption and related health problems like anxiety and hyperactivity. Early studies on the most common replacement, bisphenol S (BPS), suggest it may mimic estrogen in the body and lead to hormone disruption, though the evidence remains inconclusive.

To limit exposure to both BPA and BPS, cook or store food in heat-safe glass, stainless steel, or porcelain containers—unlike plastic, none of these materials leach chemicals.
