I've been thinking about and saying the phrase food as medicine a lot lately. But it wasn't until recently that I found out this comes from something Hippocrates said.

In fact, it's alluded to in the classical version of the Hippocratic Oath.

"I will apply dietetic measures for the benefit of the sick."

Of course, the modern version doesn't say anything about diet. Read this article for details.
