I think the one I read was the second version........I never read the first so cannot compare. I believe I benefited very much from the information presented in the book regardless that he was touting his website a lot, and also repetitive...to me that works being repetitive so I can retain the info better!! It made me realize more (I had always suspected) about the crooks in the food and drug industry, and how that is harming us......I have changed my diet very much since then and have completely eliminated drugs except for one thyroid medication which I am trying to slowly wean myself off this. I actually purchased several of the books for my family and friends...I haven't heard any feedback yet so who knows if they even read it.....
