Walking around your local outpost of Whole Foods, the Austin-based supermarket chain with nearly 400 locations in the U.S., U.K., and Canada, it's pretty easy to tell that it's not your everyday supermarket. Their offerings are quite different from what you'll find at your local Safeway, and in fact there are more than 80 ingredients that the store considers to be "unacceptable," and won't allow in any of the products they sell.
