Query: A little superhuman, but wonderful advice

Overall I love the information presented in this book. It's not fascist or self hating, but holistic and comes from a very positive place. There is simply no way I'm going to give up my morning coffee, but I've implemented some of the advice (vitamins, drinking less juice, avoiding sugar as much as possible, maybe getting that shower filter when I have a moment) that is keeping my tummy a little trimmer with a lot less effort and my nails stronger. In addition I love her approach to beauty, not a fear driven approach, but very positive, embracing who you truly are. Incidentally, I've seen a lot of her claims backed up in other health and beauty articles I've read. Also, and most importantly, for people suffering from stomach issues, a lot of this advice prevents inflammation and irritation.
