If you are interested in how your stomach works in simplistic easy to understand terms, this book is fantastic. The book takes the reader through how each stage of the digestion system functions from mouth to excrement. The book includes information on the microbiota, various bacteria, parasites and the link between these things and a healthy body. Enders also explains how a disrupted biota, caused from caesarean birth or inappropriate antibiotic use for example, can result in an allergy and/or susceptibility to disease. She explains how various bacteria communicate with the body, which can result in cravings. Lastly she provides an explanation of how prebiotic and probiotics work. The book is simple enough for a twelve-year-old to read, yet complex enough for adults like myself, who don’t have a background in science. I highly recommend this book to everyone regardless of whether you have stomach problems or not.
