MOST raw food book authors who has written a book about raw food do NOT look healthy and look older than they really are. Some of them are even OVERWEIGHT(which is proof that they do NOT eat a raw food diet themselves if they are FAT). Not one of the raw food book authors are AMA(American Medical Association) registered doctors. These book authors are just normal people like you and me that decided to write a book after reading another book that somebody else wrote and make money off selling the book. Doctors and dieticians stress how important it is to eat a balanced diet. And a strict raw food diet is NOT a balanced diet.
ANYBODY can write a book on any subject in the world and get it published. It doesn't mean that it is true. And a strict raw food diet is NOT healthy if you are already healthy.
