A new podcast from Decorah-based Seed Savers Exchange asks residents to look beyond the grocery aisle—and even the garden—to understand what shapes the food on their plates. The organization’s third episode of Sowing Connections, titled What Shapes What We Eat?, connects seed genetics, farming systems, industry marketing and food policy to the foods that reach household tables.
The 41-minute, 43-second episode is designed for gardeners, farmers and shoppers interested in the path from seeds to grocery-store shelves. Its central argument is that food choice is not only an individual decision. The systems that determine which foods are produced, promoted and sold also influence the options available to consumers.
Why seed diversity matters
The program opens with field notes from Seed Savers Exchange about maintaining open-pollinated seeds. The organization uses careful isolation practices to keep varieties true to type while protecting their genetic diversity for future generations.
That work is presented as more than a preservation project. According to the episode, the seeds that gardeners and farmers save, share and grow can influence the variety and resilience of the food system over time. For local growers, the discussion draws a direct line between preserving a plant variety today and maintaining future choices for communities.
The episode then broadens its focus from plant genetics to the economic and political forces that affect diets and grocery selections. Topics include industrial agriculture, food policy, ultra-processed foods and food-industry marketing.
Marion Nestle discusses food policy
The featured guest is Marion Nestle, whom Seed Savers Exchange identifies as a nutritionist, consumer advocate, award-winning author and academic focused on the politics of food and dietary choice. Her work examines the scientific, economic and social forces that affect what people eat and how those decisions connect to health.
Nestle’s portion gives particular attention to marketing. Rather than assigning responsibility for dietary decisions entirely to individuals, the conversation considers how industry practices and public policy help shape those decisions.
The episode also discusses possible steps for gardeners, farmers, communities and policymakers seeking a healthier and more resilient food system. It presents food-system change as a shared effort involving the varieties people grow, the markets they support and the policies that govern production and promotion.
The “Corgi” pea offers a practical example
The closing segment highlights the “Corgi” pea, described as a sweet and versatile heirloom variety in the Seed Savers Exchange collection. The pea illustrates the episode’s broader point: the future of the food system begins with the varieties people choose to save, share and grow.
Nestle’s conversation begins at 6:25 in the episode, while the “Corgi” pea segment starts at 39:23. Listeners can access the program through the Seed Savers Exchange podcast webpage, YouTube, Apple Podcasts and Spotify. Seed Savers Exchange also offers access to a collection of thousands of varieties, along with information about requesting the “Corgi” pea.
