Running on Fumes: Strawberry’s Dirty Secret

, ,

In order for our hero, the strawberry, to defeat its nemesis, a fungus called wilt, the aromatic red fruit makes a deal with the devil—and duly becomes America's favorite berry. But its success relies on fumigants, toxic gases injected into the soil that kill everything in their path. So what are fumigants; what's their effect on farm workers, local communities, and the environment; and can the strawberry break free of their poisonous grip? Listen in this episode to find out!

Omega 1-2-3

, ,

Based on all the hype, you'd be forgiven for believing that the fish oils known as omega-3s are 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.

Super Fry: The Fight for the Golden Frite

, ,

Shoestring, waffle, curly, or thick-cut: however you slice it, nearly everyone loves a deep-fried, golden brown piece of potato. But that's where the agreement ends and the battles begin. While Americans call their fries "French," Belgians claim that they, not the French, invented the perfect fry. Who's right? This episode, we take you right into the heart of the battle that continues to be waged over who owns the fry—who invented it, who perfected it, who loves it the most? And then we take you behind the scenes into another epic fight: the struggle for the perfect fry. Can food scientists create a fry with the ultimate crispy shell and soft inside, one that can stay that way while your delivery driver is stuck in traffic? Plus, the condiment wars: does mayo really have the edge over ketchup? Listen in now to find out!

Eat This, Not That: The Surprising Science of Personalized Nutrition

, ,

This episode, we've got the exclusive on the preliminary results of the world's largest personalized nutrition experiment. Genetic epidemiologist Tim Spector launched the study, called PREDICT, to answer a simple but important question: do we each respond to different foods differently? And, if so, why? How much of that difference is genetic, how much is due to gut microbes, and how much is due to any one of the dozens of other factors that scientists think affect our metabolic processes? You’ve heard of personalized medicine, will there be such a thing as personalized diets? And should there be? Can teasing out the nuances of how each individual body processes different foods make us all healthier? To find out, we signed ourselves up as study participants, sticking pins in our fingers, weighing our food, and providing fecal samples, all for science—and for you, dear listeners. Listen in now as we take part in this ground-breaking study, discover our own differences, and find out the early results!

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!
