a cancer survivalist's MUST HAVE. if you plan on making it and really giving it your all and can take on the challange of diving into a world of new eats, recipes and vitamins the natural way, this book is my favorite! it even comes with a dvd to make the book a bit easier to get around in. it explains whats all in vitamins and what they are for. the book explains foods why and why not.it simply explains the why you should and should not of almost everythhing you put in your body. and it also touches on cancer and how it kinda started in you.
