I do know some people who eat only raw food and promote that diet - I guess that's the ultimate in unprocessed-ness. I try to start with minimally processed ingredients and make them into food myself, for the most part: I make granola, for example, but it's made from rolled oats, oil, honey, nuts, seeds, and dried fruits, all of which are "processed" in some sense of the word. But I feel that this is still better than buying commercial granola.
