In this episode, Dr. Sarah Ash joins us to break down the buzz, and the backlash, around seed oils. We dive into the science of inflammation, how omega-6s interact in the body, and why understanding a little organic chemistry goes a long way to help make sense of nutrition claims. We also explore how fear-based messaging spreads online, how food influencers keep their audiences hooked, and why nutrition advice often falls apart when it promises a silver bullet. Dr. Ash reminds us that “when you try to oversimplify that one thing, it often just falls apart.”

In this episode, Katie and Bhavisha take a step away from the data and into the harder, often unspoken questions that shape science communication in practice. We reflect on what it means to do this work in spaces where expertise, public values, and lived experience do not always align, and where simply presenting the facts falls short. Drawing on our own experiences, we talk through moments where advocating for evidence can feel at odds with maintaining trust, and where stakeholder perspectives surface real tensions around trade-offs, not just misunderstandings. We also unpack the role of social media in shaping how science is shared, interpreted, and challenged, and how these platforms can both amplify and complicate communication efforts. Throughout the conversation, we come back to the idea that these tensions are not problems to solve, but conditions to work within, and that learning to sit with them is part of becoming a more thoughtful and effective communicator.

In this episode, Dr. Melinda Knuth joins us to unpack the science and social dynamics behind glyphosate, one of the most widely used and debated weed control products. Dr. Knuth explains what glyphosate is, how it works, and how recent lawsuits, questions about scientific transparency, and differing global health conclusions have contributed to public uncertainty. From a consumer behavior perspective, we explore how trust, social media, and peer-to-peer communication shape public perceptions more than traditional institutions. We also discuss how personal values, including preferences for “natural” and organic products, influence decision making and contribute to common misunderstandings about pesticide use. Finally, the conversation highlights how both consumers and producers weigh effectiveness, cost, and safety along with the role of affordability and social factors. Tune in for a thoughtful discussion on scientific uncertainty and how clear, transparent communication can help people navigate complex issues.
