Food history and science, hidden inside everyday things we eat.
Gastropod treats food as evidence: a tomato field, a sushi roll, a pancake race, or a nutrition label can all open onto a larger story. Its episodes move patiently between expert voices, kitchen scenes, cultural history, and the systems that decide what people eat.

Gastropod explores food through the combined lenses of science, history, and culture. Hosts Cynthia Graber and Nicola Twilley build episodes around a single food, ingredient, technology, or policy question, then follow it through labs, farms, archives, kitchens, and expert interviews. The show can turn canned tomatoes into a story about plant genetics, mechanical harvesters, California agriculture, and the mythmaking around San Marzano tomatoes. It can also use pancakes or tacos to unpack migration, branding, religious customs, racism in advertising, and the shifting boundaries of food categories. Recent episodes cover topics such as U.S. dietary guidelines, yogurt microbes, synthetic food made from air, and the industrial systems behind pantry staples. The tone is accessible and playful, but the reporting is dense with specific historical and scientific detail. Graber and Twilley often begin with a sensory or everyday question, then widen the frame until the listener sees the food as part of a much larger system. Guests include historians, scientists, farmers, food writers, agronomists, and industry specialists. The show is especially strong when explaining how public beliefs about health, authenticity, or tradition are shaped by technology, policy, commerce, and accident. It is a good fit for listeners who like food stories with real research behind them rather than recipe chat or restaurant reviews.
Made for: For curious listeners who enjoy food, history, science, agriculture, public health, and cultural backstories told through reported narrative and interviews.
What sets it apart: Gastropod stands out by combining field reporting, expert interviews, food science, and historical context in each tightly focused food story.
Food with a side of science and history. Every other week, co-hosts Cynthia Graber and Nicola Twilley serve up a brand new episode exploring the hidden history and surprising science behind a different food- or farming-related topic, from aquaculture to ancient feasts, from cutlery to chile peppers, and from microbes to Malbec. We interview experts, visit labs, fields, and archaeological digs, and generally have lots of fun while discovering new ways to think about and understand the world through food.
