Food fads, revisited

Food fads, revisited

Food fads are a thing. Every year, it seems, we learn about something else we should or shouldn’t do or eat for so-called optimal health. Milk is in until it isn’t. Alternate kinds of milk are in until they aren’t. We can eat based on our blood types. We can use ancient traditions. We can even get into gastro-molecular inventions (what!?).
