"The worst thing about food science, the elephant in the room, is that it's not just the opinions that are changing-but the 'facts' themselves shift too."

Did you know that the great philosophers were the original foodies? To eat or not to eat? That's an easy question to answer. But what to eat? That's a deep and profoundly difficult one.

No one thought to ask the philosophers-those rational souls devoted to truth, ethics, and reason-what they think. Until now.
