Feel the Beet: The Most Fascinating Woman You've Never Heard Of
4w ago00:44:52Tap to summarizeFor those who like its earthy flavor, the humble beet can do a lot for a salad or a soup. But could it help end slavery? In the 1800s, one woman believed it could—and she wasn't just any old woman. This episode, meet Lydia Maria Child, who wrote the first children's periodical magazine, the first New England historical novel, and one of America's first successful self-help books—all before she turned thirty, in an era where women were still considered property. This episode, we've got the fascinating story of why she bet big on beets, as well as how, more than a century later, Wolfgang Puck and Martha Stewart paired this much maligned vegetable with goat cheese to spark today's beet renaissance. Meanwhile, for the haters among us: is it possible to de-beet the beet, and get rid of that earthy flavor altogether? Listen in now as we meet the astonishing Lydia Maria Child, in the curious tale of the beet. Learn more about your ad choices. Visit podcastchoices.com/adchoices

Protein, Pyramids, and Politics: The Forgotten Stories and Controversial Science Behind Government Dietary Advice
Apr 700:55:00Tap to summarizeICYMI, our old friend the food pyramid has been flipped on its head. The Trump administration recently issued new dietary guidelines that it says will "revolutionize our nation's food culture." It's a bold claim—but since when has the government been in the business of telling us what to eat in the first place? How does it know how much of each nutrient will keep us healthy, and why are all the different forms of this advice—the Recommended Daily Allowances or RDAs, those Daily Values on food packaging nutrition labels, and the ever-shifting food pyramid—so confusing, and even contradictory? This episode, we're going back to the beginning to make sense of it all, with some help from pioneering women scientists, horses in obstacle courses, and, of course, Dick Van Dyke. Grab your climbing gear and join us to scale the food pyramid, wade through the swamp of alphabet soup acronyms, and, finally, figure out what this all has to do with what ends up on your plate.

Sushi's Extraordinary Evolution: From Pickle to Primetime
Mar 2400:45:29Tap to summarizeSushi is everywhere these days—in grocery stores and gas stations, at buffets and birthday parties, in Europe and Latin America and all over the United States. This popularity is especially astonishing when you remember that, just a few decades ago, the idea of eating nuggets of raw fish and rice seemed bizarre, intimidating, and even a little gross to most non-Japanese people. Even more surprising? The simple nigiri and maki rolls we think of as “traditional” sushi are relatively recent inventions, too. This episode, we’re going back to sushi’s origins as a cheesy-tasting fermented fish pickle, to tell the story of how impatience, war, and the 1980s—the glory days of yuppies, Sony Walkmans, and The Breakfast Club—transformed it into the seafood snack we know and love today. Plus listen in now to hear why you're eating sushi all wrong—and what you're missing out on as a result. Learn more about your ad choices. Visit podcastchoices.com/adchoices

SNAP To It! Why Food Stamps Matter To All of Us—And Why They're Under Threat
Mar 1000:46:45Tap to summarizeSNAP—the federal assistance program better known as food stamps—helps put food on the table of nearly one in eight Americans today. But, as new legislation is phased in over the coming months, more than half of those people are expected to lose some or all of their SNAP benefits. This episode, we're getting to the bottom of why SNAP matters—to all of us, not just those who receive it. Why does the U.S. government give people money just for food, rather than cash, as in other countries? Does it make sense to ban SNAP from being used to buy junk food? And why are so many people still hungry, when American farmers produce more food than we can even eat? For decades, the food stamp program has been the main way the U.S. government puts food on the tables of folks who would otherwise struggle to afford it; for all of those decades, it's been attacked, resented, and subject to political horse-trading. Listen in now, as we explore how SNAP has survived for so long—and whether it's worth saving today. Learn more about your ad choices. Visit podcastchoices.com/adchoices

It turns out the sweet, syrup-covered stack of American breakfast fame are far from the only members of the pancake family—and there are some truly controversial cakes in the wider pan family.

Join us for the shocking story of Aunt Jemima, stay for the great pancake debate, and don't blame us if you end up craving something flattish, fluffy, and floppy for your next meal!
