The Birds and The Bugs

Chicken is such a mainstay of the contemporary American dinner table that it seems hard to imagine that, just a century ago, it was rare and expensive. But over the course of the 20th century, both chickens and the chicken industry exploded in size. Much of that growth can be attributed to the miraculous properties of antibiotics, which were developed to fight human diseases but quickly began to be fed to farm animals in vast quantities. Journalist and author Maryn McKenna weaves these two intertwined tales together in her new book, Big Chicken: The Incredible Story of How Antibiotics Created Modern Agriculture and Changed the Way the World Eats. In this episode of Gastropod, she describes the consequences of decades spent feeding chicken antibiotics, in terms of chicken flavor, poultry well-being, and, most significantly, human health.

It’s Tea Time: Pirates, Polyphenols, and a Proper Cuppa

This week, Gastropod tells the story of two countries and their shared obsession with a plant: Camellia sinensis, otherwise known as the tea bush. The Chinese domesticated tea over thousands of years, but they lost their near monopoly on international trade when a Scottish botanist, disguised as a Chinese nobleman, smuggled it out of China in the 1800s, in order to secure Britain's favorite beverage and prop up its empire for another century. The story involves pirates, ponytails, and hard drugs—and, to help tell the tale, Cynthia and Nicky visit Britain's one and only commercial tea plantation, tucked away in a secret garden on an aristocratic estate on the Cornish coast. While harvesting and processing tea leaves, we learn the difference between green and black tea, as well as which is better for your health. Put the kettle on, and settle in for the science and history of tea!
