Forget Plain Vanilla: You'll Never See The World's Favorite Flavor the Same Way Again

Today, 'vanilla' often means boring, and yet the edible seedpod of this Central American orchid is one of the most expensive spices in the world, not to mention one of the most popular flavors globally. So how did this coveted bean get such a ho-hum reputation? Listen in this episode as Gastropod travels to vanilla's homeland in the highlands of Veracruz, Mexico, to investigate. It's a tale of botanical piracy, beaver butts, and ice-cream barges, in which an ingenious enslaved tween and the product of pulp paper waste combine to transform vanilla from a complex and sophisticated elite treat into the single-note synonym for dull. Plus, we meet the thrilling alternative vanillas we're all missing out on, and serve up the recipe for a vanilla tasting party that's guaranteed to make you fall back in love with the world's favorite flavor.

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. Learn more about your ad choices.

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 [https://liberalarts.du.edu/about/people/carol-helstosky], author of Pizza: A Global History [https://bookshop.org/books/pizza-a-global-history/9781861893918], and Francisco Migoya, head chef at Modernist Cuisine [https://modernistcuisine.com/], 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) Learn more about your ad choices.

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! Learn more about your ad choices.
