Gulp: Adventures on the Alimentary Canal

“America’s funniest science writer” (Washington Post) takes us down the hatch on an unforgettable tour. The alimentary canal is classic Mary Roach terrain: the questions explored in Gulp are as taboo, in their way, as the cadavers in Stiff and every bit as surreal as the universe of zero gravity explored in Packing for Mars. Why is crunchy food so appealing? Why is it so hard to find words for flavors and smells? Why doesn’t the stomach digest itself? In Gulp we meet scientists who tackle the questions no one else thinks of or has the courage to ask. With Roach at our side, we travel the world, meeting murderers and mad scientists, Eskimos and exorcists (who have occasionally administered holy water rectally), rabbis and terrorists who, it turns out, for practical reasons do not conceal bombs in their digestive tracts.
