the proven experience of the author's knowledge, the construction of the book, the passion he put it there too, all combine to make this book a must in the library of every person who cares about his health . Medicine modern would have a lot to learn, and all the pseudo nutritionists and other charlatans regimes "miracles" or "thinness", not to mention industrial plaguing us all the time, yes ALL all have much to gain from study this book, to endorse the recommendations it contains. So of course it only deals mostly vegetable juice, but I guarantee it: this book is a valuable ally, the health benefits are just obvious. Invest in a juicer, you will not regret it;)
