I've found a lot of books that are helpful, but none I'd recommend buying (other than the two I've mentioned). The library is great for these things...
I do recommend going to Whole Foods or another natural food store and looking at their books. The management usually has pretty good sense about having good books (versus fad and hype books) on the shelves. That way you can get a sense of what kinds of books you like. Then, again, hit the library.
