Omega 1-2-3 (encore)

Today, it’s a breakfast staple, but, as recently as 1960, The New York Times had to define it for readers—as “an unsweetened doughnut with rigor mortis.” That’s right, this episode is all about the bagel, that shiny, ring-shaped, surprisingly dense bread that makes the perfect platform for cream cheese and lox. Where did it come from? Can you get a decent bagel outside New York City? And what does it have in common with the folding ping-pong table? Come get your hot, fresh bagel science and history here!

For as long as we’ve been making Gastropod, co-host Nicky has also been working on another project: writing a book all about refrigeration. Well, time to pop the champagne you’ve had stashed in the icebox, because that book comes out June 25—and we’re giving Gastropod listeners an exclusive preview! This episode, Cynthia and Nicky talk about how a high school dropout's get-rich-quick scheme, some deadly explosions, and lots and lots of beer brought us the humming boxes of cold now ubiquitous in the modern kitchen—and how the proliferation of this portable, on-demand winter has transformed our food (not always for the better) while heating up our planet. It's almost impossible to imagine living without a fridge, but Nicky’s book totally changed the way we look at preserving food. Is there a better way? Listen to find out, and for the rest of the story, be sure to pre-order Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves! Learn more about your ad choices.

Based on all the hype, you'd be forgiven for believing that the fish oils known as omega-3s are the solution to every problem. Heart disease, dementia, depression, even obesity—the list of ailments that experts claim a daily dose of omega-3 can help prevent seems endless. And with more than ten percent of Americans taking a capsule of fish oil daily, omega-3s are one of the most profitable supplements in the world, too. Listen in this episode, as author Paul Greenberg and scientist JoAnn Manson help us figure out what these supposedly miracle molecules are, and what consuming them is doing to our bodies—and to our oceans.

Your pantry's sweetest ingredient has an extremely bitter history. The sap-producing grass known as sugarcane has been grown and enjoyed by humans for at least 10,000 years, but it was only relatively recently that it went from a luxury to an everyday ingredient—a change that also triggered genocide, slavery, and the invention of modern racism. In this episode, how the Crusades got Europeans addicted to the sweet stuff, and how that appetite deforested southern Europe and kicked off the trade in enslaved Africans, before decimating indigenous populations in the New World and codifying racism into law. It's a dark story that involves Christopher Columbus' mistress, the early human rights advocate whose campaign to save indigenous people encouraged the horrors of the transatlantic slave trade, and a trip to southern Louisiana, where we met Black sugarcane farmers to explore sugar's troubling legacy there. No sugar coating here: join us for the fascinating and horrifying history of this household staple. Learn more about your ad choices. Visit podcastchoices.com/adchoices

From our friends at Switched on Pop: Where were you when you learned that the McDonald's jingle "I'm lovin' it" was originally part of a full-fledged pop song by Justin Timberlake and Pharrell that flopped on the charts but found staying power as a slogan? For us, it was recording our live episode about sponsored content in pop back in March 2024, and we have not been the same since. Shaken by this revelation, we found ourselves asking, "What else don't we know about fast food jingles?" Turns out, it's a lot. From Taco Bell to Popeye's to Chili's, the music of fast food represent some of the most familiar melodies in society, across state lines and generations. But the stories behind those songs, and the way that fast food production and pop music production often move in parallel, was something we never saw coming. Since we are music experts but amateur foodies, we invited the brilliant hosts of Gastropod, Cynthia Graber and Nicola Twilley, to help serve up the history of fast food and its changing role in culture. Tune in and pig out with us as we listen and debate the artistic and ethical implications of the sounds of fast food. Learn more about your ad choices. Visit podcastchoices.com/adchoices

When you go out for a meal, it’s not just what's on your plate that matters, it's what's in your eardrums, too. From dining rooms so loud you have to shout to be heard, to playlists that sound like a generic Millennial Spotify account, it's not surprising that sound is the single most complained about aspect of restaurants. This episode, Gastropod explores the science behind the sonic experience of eating. Are restaurants really getting louder, and, if so, why? What does it take to create the perfect acoustic environment for dining? Can restaurateurs design their playlists to make customers order more or eat faster?

You've probably never heard of David Fairchild. But if you've savored kale, mango, peaches, dates, grapes, a Meyer lemon, or a glass of craft beer lately, you've tasted the fruits of his globe-trotting travels in search of the world's best crops—and his struggles to get them back home to the United States. This episode, we talk to Daniel Stone, author of The Food Explorer, a new book all about Fairchild's adventures. Listen in now for tales of pirates and biopiracy, eccentric patrons and painful betrayals, as well as the successes and failures that shaped not only the way we eat, but America's place in the world.

In his day, Luther Burbank was a horticultural rock star: everyone from opera singers to movie stars and European royalty to an Indian guru traveled to Santa Rosa, California, to meet him. Dubbed the "plant wizard," Burbank invented the plumcot and the stoneless plum, the white blackberry, and the potato variety used in every French fry you've ever eaten—as well as some 800 more new-and-improved plants, from walnuts to rhubarb. His fame as a plant inventor put him in the same league as Thomas Edison—but, while Edison patented his light bulb and phonograph, Burbank had no legal way to protect his crop creations. Listen now for the story of Luther Burbank, the most famous American you've never heard of, and how his struggles shaped what's on our supermarket shelves today, but also led to a world in which big companies like Monsanto can patent life. It's a wild ride that involves the death spiral of the Red Delicious and the rise of the Cosmic Crisp apple, as well as coded notebooks, detective agencies, rogue farmers, and a resistance movement led by former New York City mayor (and subsequent airport namesake) Fiorello La Guardia.

Americans eat more shrimp than any other seafood: on average, each person in the US gobbles up close to six pounds of the cheap crustaceans every year. We can eat so many of these bug-like shellfish because they’re incredibly inexpensive, making them the stars of all-you-can-eat shrimp buffets and single-digit seafood deals. But we've got bad news: this is one bargain that's too good to be true. More than 90 percent of the shrimp we eat comes from overseas, where looser regulations lead to horrific labor abuses, environmental destruction, and the use of banned chemicals and antibiotics—all while American shrimpers struggle to survive. This episode, we’re exploring the history of how shrimp went from a fancy delicacy to buffet bargain (yes, Forrest Gump is involved), plus what to do if you want to enjoy everybody's favorite seafood with a clear conscience. Hold the cocktail sauce: this episode will change how you look at your favorite appetizer forever. Learn more about your ad choices. Visit podcastchoices.com/adchoices

If we at Gastropod were asked to name a perfect food, the oyster would be at the top of our list. Oysters are pretty much always our answer to the question of what we'd like to eat this evening—but are they also the answer to the slow-motion disaster of disappearing coastlines worldwide? Join us this episode as we discover how this magical mollusk contains a pearl of hope in the fight to counter rising sea-levels, prevent erosion, and buffer storm surges everywhere from hurricane-hit New Orleans to New York City's flood-prone fringes. But be prepared: you just might join the ranks of the oyster obsessed. Learn more about your ad choices. Visit podcastchoices.com/adchoices
