A new podcast from Decorah-based Seed Savers Exchange is asking a broad question about everyday meals: how much control do individuals really have over the food available to them? The 41-minute, 43-second episode explores how seed genetics, agricultural systems, food-industry marketing and public policy influence what reaches grocery-store shelves.
Released August 23, 2026, the episode is the third installment of Seed Savers Exchange’s Sowing Connections series. It is designed for gardeners, farmers and shoppers who want to understand how food moves from seeds to the marketplace.
Decorah residents and listeners elsewhere can access the episode through Seed Savers Exchange’s podcast webpage, YouTube, Apple Podcasts and Spotify. The episode is available as the organization continues its work with open-pollinated seeds and the preservation of plant varieties.
Why seed diversity matters
The discussion begins with Seed Savers Exchange’s approach to 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 form of agricultural preservation. Seeds saved, shared and grown by gardeners and farmers can affect the range and resilience of the wider food system over time. The podcast suggests that preserving a plant variety today can help communities retain more choices in the future.
From seed preservation, the episode moves into the economic and political forces that influence diets and grocery selections. Its topics include industrial agriculture, food policy, ultra-processed foods and food-industry marketing.
Together, those subjects frame food choices as decisions shaped not only by personal preference, but also by the systems involved in producing, promoting and distributing food.
Marion Nestle examines marketing and responsibility
Nutrition scholar Marion Nestle is featured in the episode. Seed Savers Exchange identifies her as a nutritionist, consumer advocate, award-winning author and academic whose work examines the politics of food and dietary choice.
Nestle’s segment considers whether dietary decisions should be treated solely as an individual responsibility. It also examines how industry practices and public policy can influence those decisions. Listeners who want to go directly to that portion can begin at the 6:25 mark.
The Corgi pea brings the issue home
The episode closes with Seed Savers Exchange’s heirloom Corgi pea, described by the organization as a sweet and versatile variety in its collection. The segment uses the pea as a local example of the broader argument that the future of the food system begins with the varieties people choose to save, share and grow.
The Corgi pea segment starts at 39:23. Seed Savers Exchange also provides access to a collection of thousands of varieties and information about requesting the pea.
For gardeners, farmers, communities and policymakers, the episode points toward shared action rather than a single solution. Its central message links the varieties people grow with the markets they support and the policies that govern food production and promotion.
