Dr. Joseph Mercola was recently featured on iHeartRadio’s KFI-AM 640 program Wake Up Call with Amy King, a widely listened-to Los Angeles-based show. The segment reached a large audience, with reported listenership of over 640,000 and more than 26 million monthly digital users, highlighting growing public interest in environmental health topics.
During the interview, Mercola described how these substances can enter daily life through water, air and common consumer products. He pointed to research suggesting widespread exposure, noting that both PFAS and microplastics have been detected in a large portion of the population. The discussion also touched on how produce may be affected through environmental contamination, though exposure sources vary widely.
Mercola emphasized that while reducing exposure can be challenging, some steps may help limit contact with these substances. At the same time, the topic remains an evolving area of research, with scientists continuing to study how these exposures relate to long-term health outcomes and what level of risk they may pose.
