content: I read health and nutrition books for pleasure and this was one I could barely get through. It was translated and perhaps thats why it is so hard to follow. The book skips around and gives little solid information. Also,if you are looking for information on how to use chitosan as an aid to weight loss, you will NOT find any information here. The info. on weight loss is limited to a paragraph and sketchy at best. Maybe chitin-chitosan is a miracle but you will be hard pressed to understand why in this book.
