Not all conversation is appropriate for the dinner table – and that includes, strangely enough, the subject of eating. Yet what happens during the time that food enters our mouth and its grand exit is a model of efficiency and adaptation.
Author Mary Roach takes us on a tour of the alimentary canal, while a researcher describes his invention of an artificial stomach. Plus, a psychologist on why we find certain foods and smells disgusting. And, you don’t eat them but they could wiggle their way within nonetheless: surgical snakebots.

Martin Wickham – Head of Nutrition, Leatherhead Food Research, U.K.
