In this episode, I sit down with Dr. Leo Trasande, one of the country's leading experts on environmental health and toxic exposures, to discuss the growing threat of microplastics, PFAS, and endocrine-disrupting chemicals.

We explore how these substances are affecting fertility, metabolism, brain development, chronic disease, and long-term public health—and why the economic costs are staggering. Dr. Trasande explains how plastics enter the body, what they may be doing once they're there, and what Americans can do to reduce exposure.

We also discuss HHS's new STOMP initiative and the effort to understand and confront the impact of toxic chemicals on human health.
