  • Summary

  • 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.

  • Seed Oil Scare: The Curious Case of Canola

    Seed Oil Scare: The Curious Case of Canola
    Apr 8 2025
    If you've been hearing that canola is a killer, you're not alone. It's one of the so-called "hateful eight" seed oils: Robert F. Kennedy, Jr. says it's among the most deadly things you can eat, and Joe Rogan agrees. But is it true? This episode, we get to the bottom of the debate over the plant formerly (and still, in some places) known as rapeseed. Why does it have such an unfortunate name, and how did it transform into canola, at least in North America? Is it really engine oil? Does it actually contain a poisonous solvent? And why on earth are Brits buying up a fancy cold-pressed version by the gallon, as the new, home-grown olive oil? Are they roasting their potatoes with an inflammation- and disease-causing disaster? Listen in for the forgotten history and slippery science of this much discussed, little understood oil. Learn more about your ad choices. Visit podcastchoices.com/adchoices

  • Nutrition Advice Decoded: What Foods Are Actually Good For Us, What Should We Avoid, and Why Is It All SO Confusing?

    Nutrition Advice Decoded: What Foods Are Actually Good For Us, What Should We Avoid, and Why Is It All SO Confusing?
    Mar 25 2025
    Are eggs going to give you high cholesterol, or are they the base of a great protein-rich meal? Will coffee give you cancer, or will it help you live longer? If you're confused about what nutrition science has to say about which foods are healthy and which are not, you're not alone. But why is it so hard to figure out what's good for us, and why does the advice seem to change constantly? This week on Gastropod, we reveal the hidden history of how nutrition science got started, why its early successes saved millions of lives, and how those successes then led the field astray. From debunking the Blue Zones, to the discredited “French paradox” that had everyone washing their Brie down with glasses of red wine, to the most recent research on ultra-processed foods, we’re breaking down how nutrition research actually gets done—and what that means for what should be on your plate.

  • The Rise and Fall of Quinoa: From Incan "Superfood" to Buddha Bowl Basic

    The Rise and Fall of Quinoa: From Incan "Superfood" to Buddha Bowl Basic
    Mar 11 2025
    Quinoa is everywhere these days, the base for a million salads and grain bowls. But, until recently, barely anyone outside the nutritious seed's ancient's homeland—the Peruvian and Bolivian Andes—had ever heard of it. This week, we're telling the story of how a gorgeous spinach-like plant traditionally grown in a remote, high-altitude region of South America was transformed into one of the hottest foods on the shelves at Whole Foods. This is a tale that began with Coloradan hippies, the deliberate invention of a new Peruvian gastronomy, and beer, but truly took off when the United Nations declared that this so-called "superfood" was the secret to solving global hunger, adapting to climate change, and rescuing Andean farmers from poverty. So, did quinoa deliver? Listen in now for the story behind your next Buddha bowl. Learn more about your ad choices. Visit podcastchoices.com/adchoices

So much fun, so much information!

These two know their stuff & have fun sharing their knowledge. They cover history, science, taste, and travel with flair. They invite plenty of knowledgeable people to share as well. And the production value is good. I have been listening to Gastropod for a couple of years now and I wholeheartedly recommend it.

Absolutely Amazing

I’ve been listening to Cynthia and Nicky for years. Their dynamic together is incredible. I love how through it all they’ve kept to form as a food podcast, where others have strayed from their original content. Everything from curry to bagels and even now during the pandemic they are going strong. I eagerly await each new episode by revisiting old ones.

The perfect podcast for foodies

Lovers of food, science and history will love Gastropod. My daughter and I have been learning all sorts of interesting facts about random foods. I appreciate how deep Cynthia and Nicola dive, and their interview and conversational style is engaging and witty.
