Down the Gullet: A Guided Tour of Your Guts
In Gulp. Adventures on the Alimentary Canal, science writer Mary Roach takes a journey through the gut, exploring the secret healing powers of saliva to the taxonomy of poop. Along the trip, she serves up odd medical anecdotes, such as the story of William Beaumont, an eccentric surgeon who once ate chicken from another man’s stomach.
Mary Roach is the author of Grunt: The Curious Science of Humans at War, among other books. Her writing has appeared in Outside, Wired, National Geographic, and The New York Times Magazine, among others. She lives in Oakland, California.
