This episode, we dive into the world's longest-running, highest-stakes food fight.

ICYMI, 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 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—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
