From Fountain of Youth to Fruit on the Bottom: How Yoghurt Finally Made it Big in America
Yoghurt is the most diverse section of the dairy case: from Icelandic skyr to creamy Australian, and fruity French Yoplait to full-fat Greek. With something to suit every palate, plus a dose of microbes to support healthy digestion, yoghurt is a staple food in the US, hero of a million smoothies, berry bowls, and snack breaks every day. Which is why it's pretty weird that, until about 50 years ago, most Americans had no idea what it was. This episode, we've got the story of the microbial miracle (and ants?) that gave us yoghurt, as well as the secret connection between those heat-loving bacteria and the evolution of lactose tolerance. Plus, for most of history, yoghurt was wildly popular in large parts of the world—the Middle East, the Balkans, Caucasus, much of Asia, and the Indian subcontinent—and totally unknown elsewhere. Even the promise that yoghurt would cure old age, made by a Nobel prize-winning scientist, couldn't persuade Americans to eat it. So how did yoghurt finally capture the hearts of Americans? Listen in now for the little-known story of our curious relationship with this creamy concoction.

Yes, You Really Can Make Food From Thin Air—And We Tried It
Every second of every day, plants on earth do something miraculous: they take the carbon dioxide from air and turn it into food. With very few exceptions, everything we eat starts out that way. But what if we wanted to cut out the middlemen, re-wild all those fields full of wheat and corn, and manufacture dinner directly from the atmosphere ourselves? Scientists began dreaming of turning air into food back into the 1800s, but it's only recently that dream has become a reality—with results that, depending on where you live, you can already taste for yourself. In this episode, we’re exploring the history and science that made this particular sci-fi future real: from a space-age vodka and military-grade yogurt-like substance to surprisingly delicious gas-based butter and bonbons. Join us this episode as we explore the weird science and fascinating history behind this futuristic food, and discover how it might help us save this planet *and* survive on new ones.

Pizza Pizza!
At last, an episode on pizza! But that raises a tricky question: what exactly is pizza? As it turns out, the original pizzas from eighteenth-century Naples looked nothing like a standard slice—they were more like a focaccia, topped with oil, herbs, anchovies, or whatever else was on hand. Even after these first pizzas met the tomato, the dish was a local peculiarity—most Italians thought pizza was gross and weird until just a few decades ago. So how did we get from Neapolitan subsistence snack to today's delivery staple? Listen in this episode as we travel with historian Carol Helstosky, author of Pizza: A Global History, and Francisco Migoya, head chef at Modernist Cuisine, from Italy to New York to Brazil and beyond, to tell the story of how pizza conquered the world. All that, plus the tough questions: is Chicago deep dish really pizza? How about bananas on top? What about (gasp) a donut pizza? (encore episode)

Everything You Know About Metabolism Is Wrong
If you’ve heard of metabolism, you’ve probably heard endless tips and tricks to boost it, from working out to drinking green tea. The idea is that a slow metabolism leads to weight gain, and speeding it up makes it easier to shed pounds. But what if we told you that metabolic rate doesn't really have anything to do with why so many of us in the developed world are heavy? This episode, nutrition scientist Kevin Hall and science journalist Julia Belluz join us to debunk metabolic myths, starting with what actually happened behind the scenes on the reality TV show The Biggest Loser. Can you really mess up your metabolism by gaining and losing weight, or reset it with morning tonics and exercise? Are those of us who weigh more than we want cursed with a slow metabolism, while those of us who seem to be able to eat whatever we want without gaining weight are just lucky to have a speedy one? And what do World War I explosives and Froot Loops have to do with figuring this all out? Listen in this episode, as we debunk some metabolism myths!

Durian Delight and Feijoa Fun: Adventures in Banned, Forgotten, and Unusual Fruit
This week on Gastropod, a feast of fruits! Specifically, feijoa and durian—and, if you haven’t heard of either, you’re not alone. Unlike the ubiquitous strawberry or banana, durian and feijoa are only popular in a handful of countries and almost unknown in the US, and we wanted to know why—especially because the people who love them really love them. For New Zealanders, like journalist Kate Evans, feijoa is *the* taste of home, even though it's almost forgotten in its original homeland, in Brazil and Uruguay. Meanwhile, the smell of the durian is so intense and distinctive—Julia Child likened it to “dead babies mixed with strawberries and Camembert”—that it's famously banned from public transportation in Singapore. But for durian lovers, like the cancer expert who decoded the fruit's genome, it inspires something close to obsession. Join us this episode for a weird fruit adventure, as we discover why the durian and feijoa inspire such strong feelings, and why they never made it big in the US.

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.
