Sorta veering off-topic, but Tess, I agree. Dr. Campbell's "rat studies" were fascinating! I didn't read The China Study 'till some time after switching to a vegan diet, but I think it might have significantly influenced my decision, had I not already chosen to go vegan.
When I ordered it from Amazon, I got another book (you know how Amazon conveniently "recommends" books to go along with...) called The Vegan Diet As Chronic Disease Prevention: Evidence Supporting the New Four Food Groups and I just started reading it this week - it is amazing as well... if you ever doubted any reason to go vegan, you wouldn't after reading both these books, for SURE!!
