Truly in its infancy. The phrase I always use when in a grocery store is whether I'm purchasing things that are "recognizably food". Vegetables, fruits, meat all remind you of their original source or are identical to the original thing. Where food rates on this "eye test" degrades considerably as you move into more and more processed food. It's one of those things that feels common sense and the further along we get the more it appears that it's true. That eating an egg is worse for you than fat-free protein bars seems preposterous now, but there was a time when that was the orthodoxy.
