Gastropod

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.

      Peanuts: Peril and Promise


      Despite their diminutive scale, peanuts play an outsized role in American culture. Peanut butter has long been a mainstay of the American lunchbox, with its sticky, slightly sweet nuttiness flavoring the memories of generation after generation of kids. And it’s hard to imagine ballgames without, as the song goes, peanuts and Cracker Jacks (which, of course, also contain peanuts). But today, peanuts are the source of both hope and fear: while there’s been a surprisingly steep rise...

      Fake Food


      Hamburgers that turn out to be horse, not beef. Honey sweetened with high-fructose corn syrup. Old, grey olives dipped in copper sulfate solution to make them look fresh and green. Fraudulent foods such as these make up as much as five to ten percent of the offerings on supermarket shelves, according to experts—but which food is most likely to be faked, and what does that tell us about our food system? Join us this episode as we put on our detective hats to investigate food fraud’s...

      Here’s Why You Should Care About Southern Food


      The food of the South is one of the most complicated, complex, contradictory cuisines in the U.S. This is the region where a monumental mixing of crops and culinary traditions gave way to one of the most punishing, damaging monocultures in the country; where food born in violence and slavery led to delicious, nutritious dishes. It’s also the region that laid the tablecloth for seasonal, farm-to-table dining, as well as drive-through fast food. In this episode, authors Michael Twitty...

      Better Believe It’s Butter


      Butter is beautiful: solid golden bars add the perfect flakiness to pastry, give cake a delightfully tender springiness, and melt mouth-wateringly onto toast. But unlike its cousin, cheese—another concentrated, solidified form of milk—we don’t tend to think of butter as something that’s available in hundreds of varieties, each with a different flavor, color, and texture. Nor do we necessarily consider a dairymaid costume to be a uniform of women’s empowerment. But we...

      Meet Koji, Your New Favorite Fungus


      It’s impossible to imagine Japanese meals without soy sauce, or the umami-rich fermented bean paste called miso, or the rice-based spirit known as sake. Which means that Japanese cuisine depends on the one fungus that enables the fermentation of all these delicious foods: koji. Today, American chefs are discovering what Asian cooks have known for centuries, that koji is a microbial powerhouse with seemingly magical abilities to completely transform food. But how does a mold from a...

      V is for Vitamin


      They’re added to breakfast cereal, bread, and even Pop-Tarts, giving the sweetest, most processed treats a halo of health. Most people pop an extra dose for good measure, perhaps washing it down with fortified milk. But what are vitamins—and how did their discovery make America’s processed food revolution possible? On this episode of Gastropod, author Catherine Price helps us tell the story of vitamins, from Indonesian chickens to Gwyneth Paltrow.

      We take vitamins for...

      Hacking Taste


      Taste is the oldest of our five senses, and yet perhaps the least understood. It’s far more complicated than salty versus sweet: new research is dramatically expanding our knowledge of taste, showing that it’s intimately connected to obesity, mood, immunity, and more. In this episode, we get into the science of how taste works, why we taste what we do, and what makes supertasters unique. And finally, we hack our taste buds—for fun, but, in the future, maybe for...

      Cork Dork: Inside the Weird World of Wine Appreciation


      “There’s the faintest soupçon of asparagus and just a flutter of Edam cheese,” says Paul Giamatti in the movie Sideways. Believe it or not, he’s describing pinot noir, not quiche. The world of sommeliers, wine lists, and tasting notes is filled with this kind of language, prices seemingly rising in step with the number of bizarre adjectives. It’s tempting to dismiss the whole thing as B.S., but listen in: this episode, author Bianca Bosker takes us along on her journey...

      To Eat or Not to Eat Meat


      With flexitarianism on the rise throughout the developed world, and everyone from Bill Clinton to Beyoncé endorsing the benefits of a vegetarian or vegan diet, it can sometimes seem as though meat is just a bad habit that the majority of us are too weak-willed to kick. But is giving up meat morally superior, healthier, and better for the planet, as its advocates insist? This episode, we fearlessly dive into the long, tangled history and surprisingly nuanced science behind those claims....
