Guts and Glory

What does it mean when your stomach rumbles? How do our bodies extract nutrients and vitamins from food? Does what you eat affect your mood? Digestion is an invisible, effortless, unconscious process—and one that, until recently, we knew almost nothing about. On this episode of Gastropod, we follow our food on its journey to becoming fuel, from the filtered blood that helps slide food into the stomach, to the velvet walls and rippling choreography of the small intestine, to the microbial magic of the colon and out the other end. And we do it by visiting the world's most sophisticated artificial gut at dinner time—a plumbing marvel named TIM that chews, swallows, squeezes, farts, and poops just like the real thing.

The Great Gastropod Pudding Off

Four bakers, one evening, and one challenge: Who can steam the best spotted dick? On this week’s action-packed episode, Tom Gilliford, Selasi Gbormittah, and Yan Tsou of Great British Bake-Off fame, along with honorary Gastropod member (and Cynthia’s partner) Tim Buntel, compete to see who can master this most classic of British puddings for the first-ever Great Gastropod Pudding Off! But what in the world is spotted dick? “It's got nostalgia, mystery, horror, and comedy—it’s a perfect British dish,” explained British food designer and jellymonger Sam Bompas, who joined us to judge the competition. Listen in as Tom tries to beat his rival Selasi, Yan revives the flavor combination that robbed her of a Bake Off victory, and Tim tests out his Yankee-style pudding on the Brits. While the four bakers duke it out in the kitchen, we dive into the history and science of British pudding to find out what makes a pudding a pudding, the secret ingredient that will give your pud a lovely light texture, and why anyone would name a dessert “spotted dick.”

Potatoes in Space!

Today, a half century after Neil Armstrong took one small step onto the surface of the Moon, there are still just three humans living in space—the crew of the International Space Station. But, after decades of talk, both government agencies and entrepreneurs are now drawing up more concrete plans to return to the Moon, and even travel onward to Mars. Getting there is one thing, but if we plan to set up colonies, we'll have to figure out how to feed ourselves. Will Earth crops grow in space—and, if so, will they taste different? Will we be sipping spirulina smoothies and crunching on chlorella cookies, as scientists imagined in the 1960s, or preparing potatoes six thousand different ways, like Matt Damon in The Martian? Listen in this episode for the stories about how and what we might be farming, once we get to Mars.

The Curry Chronicles

Curry is, supposedly, Indian. But there is no such word in any of the country's many official languages—and no Indian would use the term to describe their own food. So what is curry? This episode takes us to India, Britain, and Japan on a quest to understand how a variety of spicy, saucy dishes ended up being lumped together under one name—and then transformed into something completely different as they were transported around the world. From a post-pub vindaloo in Leeds to comforting kare raisu in Kyoto, we explore the stories and flavors of curry—a dish that's from nowhere and yet eaten nearly everywhere.

The Bagelization of America

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!

Can Diet Stop Alzheimer’s?

Every three seconds, someone in the world develops Alzheimer's disease. It's a devastating disease: millions of people, as well as their caretakers, spend years dealing with disabling disorientation and memory loss. Today, it's the sixth leading cause of death in the U.S. By 2050, an estimated 15 million people in America will have Alzheimer's—the combined populations of New York, Chicago, and Los Angeles. But, after years of failed drug trials, scientists are now realizing that the disease begins with structural changes in the brain decades before sufferers show any symptoms. And some researchers now believe that diet may be the most important factor in determining whether or not those brain changes take place. Listen in now to find out: Can changing what you eat prevent Alzheimer's? …More

Seeds of Immortality

When seeds first evolved, hundreds of millions of years ago, they not only revolutionized the plant world, but they also eventually sowed the path for human civilization. Today, it's nearly impossible to eat a meal without consuming a plant embryo—or many. But how did seeds come to play such a critical role in human history? Why might one seed in particular, the lotus seed, hold the secret to immortality? And, perhaps just as importantly, how does this magical seed taste? Find out in this special episode of Gastropod, sponsored by McCormick.

Pick A Pawpaw: America’s Forgotten Fruit

In 1916, agricultural experts voted the pawpaw the American fruit most likely to succeed, ahead of blueberries and cranberries. But today, most people have never even heard of it, let alone tried it. What is the pawpaw, and how did we forget it? Listen in this episode for a tale that involves mastodons and head-lice, George Washington and Daniel Boone, and a petite but passionate community of pawpaw obsessives.

Eating to Win: Gatorade, Muscle Milk, and… Chicken Nuggets?

Ancient Greek Olympians swore by beans to give them a competitive edge. Japanese sumo wrestlers rely on a protein-rich soup called chankonabe to get into peak condition. And NBA all-stars Kevin Garnett, Carmelo Anthony, and Steph Curry credit their success to a pre-game PB&J. Throughout history, athletes have traditionally eaten something special they hope will give them an edge. But is there any science behind these special drinks and diets—and will consuming them help those of us who are not destined for sporting glory, too? Listen in this episode as we reveals the backstory behind such stadium staples as Gatorade and Muscle Milk—and the evidence for their efficacy.
