Gut: The Inside Story of Our Body’s Most Underrated Organ

It's incredible how little we know about our digestive system. I think Enders is right when she says it's become associated with dirt, refuse, and unpalatable things we prefer to avoid looking at, but it's time for that to change. The young author does a great job of presenting information in a lighthearted way that is nevertheless intellectually respectable (for the nitpicky, footnotes would help). Since the book came out there has been more research and more books on the subject, but this is still a good introduction to the topic. I hope we'll be hearing a lot more about it and that it will become, as it should be, the ground of our healthy, happy existence in an interdependent world.
