I've had a desire to become healthier and decided on doing some research to figure out how to go about doing so. I only read about 3/4 of the chapters within the book because they were all that I needed. However, Dr. Mercola was rather confusing when talking about Melanoma, I often had to go to my mom (who has recently suffered from it) to clear some things up. She agrees the what he does say about contradicts just about everything else he's said about it, but did agree with him on the chapter about vaccines. I'm takin what I HAVE read from this book and hopefully use it in the near future. However, when it comes to melanoma topics, I would really just contact a dermatologist, most of what he said was so contradictory that it sounded like crud.
