A cool, refreshing glass of orange juice is the perfect top-off to your breakfast, but maybe there are a few things you might want to know first about its history: how it got to you and what “100% pure orange juice” actually means. Both of these have to do with OJ’s sudden rise to popularity in the last half-century—hard to imagine breakfast nowadays without it—as Alissa Hamilton explains in her book, Squeezed: What You Don’t Know About Orange Juice.

Listen and be sure to check out more of her interviews and media appearances on the “Squeezed” blog.
