When did food become "Superfood"?

I'm pretty sure that all of today's "super foods" were once upon a time called "food"... just like "organic vegetables" were once called "vegetables"

The main thing you might notice about 'superfoods' is that they are all freshly grown produce. I have never seen a processed food described as a 'superfood' with the exception of dark chocolate of course.
