Why Is Pig Milk the One Milk We Don't Drink?

Stephen Dubner and Angela Duckworth explore why pig milk, despite being nutritionally viable, has never become a commercial or cultural staple in human diets, while cow, goat, and sheep milk are common. The episode examines food taboos, cultural preferences, and the contingent historical reasons why certain animals become domesticated for dairy while others don't. They also discuss personal food preferences that seem disgusting to others.
