I wish I had read this book much earlier when it came out in 2015. This is a very informative, organized and easy read. I particularly appreciated the breakdown of the probiotic family and the clear explanations on page 109. The author provides food sources of prebiotics, discusses allergies and allergy-related conditions, and explains how anxiety and depression play a factor. Moreover, the author provides the rationale for building a better biome and how to stay regular for greater health. The recipes include many ingredients, such as seeds, that many people cannot ingest, and the recipes are resourceful. There are a total of 181 pages organized into 7 chapters and a whole chapter, 6, is dedicated to fermented foods. I must say that the fermented taste is definitely an acquired taste and takes getting used to. Book includes metric conversion tables, which are helpful; an appendix; resources; notes; and a helpful index for cross-reference checks. Overall, in my opinion, this is a must-read for a holistic approach to health and well-being.
