Let’s Talk About Microplastics... (with Dr. Katie Pelch)

October 15, 2025 · 53 min

Show notes

Microplastics are having a major moment in the headlines, but there’s a lot of confusion about what they actually mean for our health. In this episode, we’re joined by Dr. Katie Pelch, Senior Scientist with the Natural Resources Defense Council, to unpack the truth about microplastics—what they are, how they get into our food and water and what the current research says about their risks to humans. So join us, two Registered Dietitians (and one environmental scientist!) as we break down the evidence and make sense of the growing conversation around plastics in our food and bodies.
