I´d say read this book as one of VARIOUS sources. Because while the authoress is definitely warm and approachable and some of the mentioned key issues are definitely worth thinking about, I also find some of the opinions presented being no more than that, opinions. Sources vary and I would like to have more "hard" data here to back up some of the points. Also the book relies too much on the naturopathy for my liking, as I am fan of more scientific approach (and my personal way to healing includes the herbs, essential oils and propolis, too - yet only after I know the "WHY" and the "HOW").
But I definitely agree with the last chapter - Emotions! One´s approach to the whole food question is so important and can signal a lot of issues, too!
