A lovingly sketched and thoroughly researched biography has just come out in paperback. It is a portrait of a dark highway, a story that starts with an aroma and also ends with an aroma; a journey through humanity, a trip through ourselves. Gulp: Adventures on the Alimentary Canal, is the latest scientific foray by Mary Roach. And it’s about the gut: what happens to our bodies when we eat and why.
