For good dairy info, check the pcrm.org web site. All of their info is really well-researched and they cite their sources.
You can also check the book Diet for a New America (lousy title, great book) by John Robbins. A new edition of that just came out - the original is from 1987, and still in print. It's a terrific book and what's amazing is that for something crammed with technical info it reads almost like a novel you can't put down.
I'd also look for books by Dean Ornish and/or James McDougall. They'll have great info with good references.
Good luck on your paper!
