This is really really good information about health in general and about health in preparation for conception. Roy Dittman has developed a comprehensive protocol on how to get your body into shape before conception, with the goal of giving successful birth to a health and intelligent child.
My only complaint with this tomb of a book is that the information in this book is not very well organized. It reads kind of like a loosely categorized brain-dump. Welcome the flood gates of information that you can't possibly synthesize and determine how to use properly without hours and hours more of additional study beyond simply reading the book! However, Dittmann himself admits that the book is not meant as a self-help guide. The protocol is really intended to be followed with the help of a trained healthcare provider. Despite that easy out, I wish that Dittmann and his editors had spent a little more time making this book more comprehensible, rather than a smorgasbord. It would certainly endear itself better to a wider range of readers, if they did.
