It's sort of half-cookbook, half-eclectic nutritional info. I can't really describe what it all says. Each page has a column down the left and right side giving more details about the recipes, or ingredients in them, or words of nutritional wisdom, or little-known facts, or excerpts from Price's research as well as all manner of books . . . it's just really good stuff. There's also an excellent chapter on nutrition at the beginning. I value this more than any other cookbook I've ever bought, and I've bought plenty over the years <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> A really good complement to Cordain's book too.
