In this two-part interview, Dr. Peter Thorne, University of Iowa Distinguished Chair and Professor of Occupational and Environmental Health and a leading expert in toxicology, provides an in-depth overview of how the federal government regulates chemicals in food, water, and air. Key points: • The EPA and FDA are science-based organizations that interpret laws passed by Congress and apply the best available science to make regulatory decisions aimed at protecting human health and the environment. • The EPA's Science Advisory Board provides independent, non-partisan oversight to ensure the agency's decisions are grounded in scientific evidence. • Chemical regulations are dynamic, with compounds like Red Dye No. 3 and inorganic arsenic being re-evaluated as new scientific data emerges. • The precautionary principle guides regulators to err on the side of safety when the evidence suggests a chemical may pose health risks, even in the absence of definitive human studies. • Replacing problematic chemicals with saf

This episode discusses physical activity and its role in preventing chronic disease, featuring an interview with Dr. Lucas Carr, an associate professor of Health and Human Physiology at the University of Iowa and leading researcher in lifestyle interventions and health behavior change. Key points include: Dr. Carr's research focuses on the behavior science behind habit formation and helping people find enjoyable, sustainable ways to be physically active as a means of prevention. His team has implemented a system to treat physical activity as a "vital sign" in healthcare settings, screening patients and connecting inactive individuals with free health coaching resources. Data from over 60,000 patients shows those who are physically active (150 minutes per week of moderate-to-vigorous activity) have significantly lower risks of 19 different chronic health conditions. Practical advice is to find physical activities you genuinely enjoy, as you're more likely to stick to something you find pleasant and rewardi
