I won't lie to you... There are some gross parts in this book, but it won't be anything you haven't encountered before unless you are rich enough to employ a butler who wipes your bum for you. That ain't me babe. I've done all of the work myself. Author Guilia Enders is a PhD student in Gastroenterology and she manages to keep the subject light enough that I giggled a few times while learning about the cutting edge science research on how we process and react to food in the body. Think of it as a supplemental users guide to the gut. If you own one you aren't required to read this, but it will definitely help!
