Query: it is a COPY of the book is, "Eat to Live."

Great information , but sadly the autors just copy the infornmation from the Dr. Joel Fuhrman's book is, "Eat to Live." The Dr Joel book is one of the BEST DIET books in the market a lot more information . better buy the original book "EAT TO LIVE "
