is for néophytes- bad price / quality ratio

This book is for beginners in the field of Zen, bio and wellness. Personally, I did not learn much (I specify that I have no training in this environment). Looking good on the internet, we find the same information.
In addition, there are many gaps in a book from 2010: the author still talks of the ANPE, AFPS whose training would be in a year (????) and misled the reader with the job of "dietitian-nutritionist". It is either dietician or nutritionist doctor, which is not at all the same thing or the same training!
I also found some shells during playback.
In short, this book is only useful to people with no knowledge in the field of organic, zen and wellness. There is a track to convert but never seen a reference was brief.
As for the price, it seems too high for a book of this quality. 10 would be the maximum in my opinion to invest.
