Sports nutrition books?

I'm looking for a good book on sports nutrition. Convinced that I wasn't
getting enough protein and just coming out of a fog of pretty accute anxiety
I decided recently to start eating meat again. Just fish and egg whites. I
feel a lot better, especially physically. I'd like to figure out, though,
having basically winged while I lost the weight and then got stuck in my
anxiety rut for a year or so, how much protein I need generally as an
athlete. Does anyone know of a good book that addresses this? I know some
books about cycling or running address it in chapters, but I'm talking about
a book dedicated to nutrition for the active person.
