The Keto Paradox: Fad Diet and Life-Saving Medical Treatment

08/22/23 • 43 min

What do some epilepsy patients have in common with tech bros, bodybuilders, and Joe Rogan? The high-fat, carb-shunning diet known as keto, whose history dates back much further than its 2010s rise to fame. In this episode, Gastropod traces how a medical treatment pioneered more than 2,500 years ago was refined in the 1920s to treat seizures. We trace its wild ride in and out of fashion, with cameos from Robert Atkins, the 80s exercise craze, and Meryl Streep. And, of course, we've got the myth-busting science on what ketosis and ketones really are, the dangers of eating this way to lose weight, and the reason this diet can be life-saving—for people with a very specific medical condition. Bust out the butter (but please don't put it in coffee) and join us down the keto rabbit hole.

Secrets of Sourdough (encore)

2 Recommendations

Today, you can find a huge variety of breads on supermarket shelves, only a few of which are called "sourdough." For most of human history, though, any bread that wasn't flat was sourdough—that is, it was leavened with a wild community of microbes. And yet we know surprisingly little about the microbes responsible for raising sourdough bread, not to mention making it more nutritious and delicious than bread made with commercial yeast. For starters, where do the fungi and bacteria in a sourdough starter come from? Are they in the water or the flour? Do they come from the baker's hands? Or perhaps they're just floating around in the foggy air, as the bakers of San Francisco firmly believe? This episode, Cynthia and Nicky go to Belgium with two researchers, fifteen bakers, and quite a few microbes for a three-day science experiment designed to answer this question once and for all. Listen in for our exclusive scoop on the secrets of sourdough. (encore presentation)

All Aboard the Tuna Rollercoaster! Join the King of Fish for a Wild Ride that Involves Ernest Hemingway and (of course) Jane Fonda

A bluefin tuna can grow to the size of a car, weigh twice as much as a grand piano, swim as fast as a running lion, and keep its muscles at human body temperature even in the ocean's coldest depths. It's also wildly delicious, with a sweet, briny, but meaty taste and a melt-in-your mouth texture that has made it the most expensive fish in the world, with a single bluefin selling for a record-breaking $3 million in 2019. Not bad for a fish that, until recently, New England fishermen used to have to pay to dispose of. This episode, we've got the story of how the king of fish went from the coin of the realm in ancient Byzantium to cat food before bouncing back, in a tale that involves Alexander the Great, Ernest Hemingway, and a couple of Canadian coffin-makers. But popularity has proven a double-edged sword for the bluefin: in the past few decades, it's been fished almost to extinction, while also becoming the poster child for saving the oceans. These days there's big news in tuna world, and, for the first time in years, environmentalists and scientists have hope for the bluefin's future. So is it time to start ordering maguro again at the sushi bar?
