This conversation is about trust before interventions, dignity alongside outcomes, and recognizing that communities...

PHEC 444: When Agriculture Meets Allergy Prevention, With Markita Lewis, MS, RD
Public Health Epidemiology Conversations

In this powerful episode, Markita Lewis, registered dietitian and leader at the National Peanut Board, reveals the surprising science behind early peanut introduction and why most families still haven’t heard the message.

The conversation goes far beyond individual risk, touching on the public’s right to access science, what years of PFAS research are revealing about everyday chemical exposures, and why cutting cancer surveillance funding now would be a dangerous mistake. From student activism and misinformation to surprising data on trust in scientists, this episode is a timely reminder of what’s at stake when science, policy,...
info_outlineIn this conversation, Dr. Charlotte Huntley welcomes back Dr. Vinu Ilakkuvan, founder and principal consultant at Pop Health and creator of Gaslit by Corporations, to explore what it really means to go “further upstream” in public health. Vinu shares how years of working with coalitions and systems-change efforts led her to focus on power—who has it, how it’s used, and why communities must reclaim it to advance health. She explains why she chose the bold framing “Gaslit by Corporations, Ignited by Community” to translate the academic idea of the commercial determinants of health into language that everyday people can connect with and act on.
Throughout the episode, Charlotte and Vinu dig into plain-language communication, narrative power, and community organizing as essential strategies for countering corporate harm and shifting policy, while also highlighting the importance of community spaces (including the PHEC Podcast Community App) to strengthen collective “civic muscle.”
