Unbiased Science

In this episode, sponsored by the American Cleaning Institute, Jess welcomes Dr. Joe Zagorski, a toxicologist at Michigan State University's Center for Research on Ingredient Safety (CRIS) to discuss microplastics — specifically what the science actually shows, where legitimate concern ends and marketing-driven panic from "all natural" brands begins. Dr. Zagorski also shares why PVA in both laundry and dishwasher pods get lumped in with conventional plastics when the evidence says it shouldn't be. In this conversation, the experts also breakdown what terms like "natural," "plant-based," and "biodegradable" really mean, and how to tell the difference between a legitimate safety concern and a brand using your anxiety to sell you something. This one's worth a listen.
