About This Episode
Dietitians warn us to limit our consumption of pepperoni pizza, potato chips, and other sodium-rich foods, but just how many ways does salt season our lives? Neil dishes with Mark Kurlansky, author of “Salt: A World History,” about the dirty secrets of salt in our food. Neil and co-host Eugene Mirman savor some other connections between salt and biology, from the origin of life on Earth to the possibility of life swimming in the salty ocean on Jupiter’s moon Europa.
