I really needed this book. I had been feeling nauseous, which was accompanied by lots of abdominal pain and weight loss. I went through a myriad of tests, scans, scopes, etc. with nothing really showing why I felt so badly. The Dr. tried me on the Low Fod-map diet, which did not help at all. Finally, my acupuncturist recommended this book – which I quickly purchased and immediately began trying to follow. The first thing I noticed was that I had almost Nothing in my kitchen that was allowed on this diet – a clear sign that I Really needed to adjust my way of eating if I wanted to feel better. I am not 100% following everything in the book, but am trying to reach a happy medium on what works best for me. (I am still allowing myself to eat small amounts of brown rice, as an example. And I am doing fine with that.) My main focus has been cutting out the sugar, wheat, and refined Omega 6 seed oils, also restricting other processed grains. I started to feel better within 2 days of eliminating the worst things, and a month later my gut is still doing Much better!
