Gulp: Adventures on the Alimentary Canal

by Mary Roach

Overview

The irresistible, ever-curious, and always best-selling Mary Roach returns with a new adventure to the invisible realm we carry around inside.

“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? How much can you eat before your stomach bursts? Can constipation kill you? Did it kill Elvis? In Gulp we meet scientists who tackle the questions no one else thinks of—or has the courage to ask. We go on location to a pet-food taste-test lab, a fecal transplant, and into a live stomach to observe the fate of a meal. 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.

Like all of Roach’s books, Gulp is as much about human beings as it is about human bodies.

What People are Saying About This

Steven Pinker

Fans of lively writing will be delighted by the newest monosyllable from Mary Roach. Once again Roach boldly goes where no author has gone before, into the sciences of the taboo, the macabre, the icky, and the just plain weird. And she conveys it all with a perfect touch: warm, lucid, wry, sharing the unavoidable amusement without ever resorting to the cheap or the obvious. Yum!—Steven Pinker, Harvard College Professor of Psychology, Harvard University, and author of How the Mind Works and The Better Angels of Our Nature

Editorial Reviews

"There is much to enjoy about Mary Roach—her infectious aw for quirky science and its nerdy adherents, her one-liners... She is beloved, and justifiably so."— Jon Ronson New York Times Book Review

"As engrossing as it is gross."— Entertainment Weekly

"Far and away her funniest and most sparkling book, bringing Ms. Roach’s love of weird science to material that could not have more everyday relevance. . . . Never has Ms. Roach’s affinity for the comedic and bizarre been put to better use. . . . “Gulp” is structured as a vastly entertaining pilgrimage down the digestive tract, with Ms. Roach as the wittiest, most valuable tour guide imaginable."— Janet Maslin New York Times

"A delicious read and, dare I say it, a total gas."— Kate Tuttle Boston Globe

"With the same eager curiosity that she previously brought to the subjects of cadavers, space, and sex, the author explores the digestive system, from mouth to colon."— New Yorker

"[A] merry foray into the digestive sciences….Inexorably draws the reader along with peristaltic waves of history and vividly described science."— Brian Switek Wall Street Journal

"You’ll come away from this well-researched book with enough weird digestive trivia to make you the most interesting guest at a certain kind of cocktail party…Go ahead and put this one in your carry-on. You won’t regret it."— Amy Stewart Washington Post

"A witty, woving romp of a book… Roach…is a thoroughly unflappable, utterly intrepid investigator of the icky."— Chloe Schama Smithsonian

"Gulp is about revelling in the extraordinary complexities and magnificence of human digestion."— The Economist

"Relentlessly fun to read."— Bee Wilson The New Republic

"Never before has the process of eating been so very interesting…. After digesting her book, you can’t help but think about what that really means."— Micki Myers Pittsburgh Post-Gazette

"One of my top criteria for pronouncing a book worthwhile is the number of times you snort helplessly with laughter and say, “Wow! Did you know that ... ” before your long-suffering spouse throws a book at you from across the room. My personal spouse says that, in this department, “Gulp” takes the cake."— Adam Woog Seattle Times

"Letting this brilliantly mischievous writer, for whom no pun is ouch and no cow sacred, dip her pen into the font of all potty humor must have seemed even riskier than her previous excursions into corpses (Stiff), the afterlife (Spook), sex (Bonk) and outer space (Packing for Mars). But dip she did—at one point she put her whole arm into a cow’s belly—and came up with another quirkily informative pop-science entertainment in Gulp: Adventures on the Alimentary Canal."— Jeffrey Burke Bloomberg

"Once again Roach boldly goes where no author has gone before, into the sciences of the taboo, the macabre, the icky, and the just plain weird. And she conveys it all with a perfect touch: warm, lucid, wry, sharing the unavoidable amusement without ever resorting to the cheap or the obvious. Yum!"— Steven Pinker, author of How the Mind Works and The Better Angels of Our Nature

"As probing as an endoscopy, Gulp is quintessential Mary Roach: supremely wide-ranging, endlessly curious, always surprising, and, yes, gut-wrenchingly funny."— Tom Vanderbilt, author of Traffic: Why We Drive the Way We Do (and What It Says About Us)

From the Publisher

…Gulp is an absolute delight…[Roach is] a very good writer who understands that her job is, above all, to entertain. Every paragraph is a pleasure to read, even if that paragraph is about a partially decomposed gazelle entombed in the body of a python…In the wrong hands, a book on digestion would be rendered tedious by a need to cover every aspect of the subject to some degree. But Roach follows her interests, not a checklist…you'll come away from this well-researched book with enough weird digestive trivia to make you the most interesting guest at a certain kind of cocktail party.

The Washington Post - Amy Stewart

Gulp is far and away her funniest and most sparkling book, bringing Ms. Roach's love of weird science to material that could not have more everyday relevance. Having graduated from corpses (Stiff), the afterlife (Spook) and sex (Bonk, full of stunts featuring Ms. Roach as guinea pig), she takes on a subject wholly mainstream. She explores it with unalloyed merriment. And she is fearless about the embarrassment that usually accompanies it…Never has Ms. Roach's affinity for the comedic and bizarre been put to better use.

The New York Times - Janet Maslin

Throughout her sojourn down the gastrointestinal tract, science writer Roach (Packing for Mars: The Curious Science of Life in the Void, 2011, etc.) enlists her abundant assets of intelligence and humor while dissecting this messy and astounding part of the human body. The author ties her curiosity about this region of the body and what many consider a disgusting or off-limits subject for polite conversation to a fifth-grade classroom encounter with a headless, limbless, molded-plastic torso: "Function was not hinted at in Mrs. Claflin's educational torso man….Yet I owe the guy a debt of thanks. To venture beyond the abdominal wall, even a plastic one, was to pull back the curtain on life itself." The author begins by detailing the subtle, complex role the nose plays in taste; why humans have trouble finding names for flavors and smells; and how the human nose can be thought of as a "fleshly gas chromatograph." Roach chronicles her visit to an oral processing lab and her interview with a prisoner who patiently explained the intimate details of utilizing the alimentary canal for illegal purposes. The author grapples with the history of flatulence and adeptly describes the torment caused by Elvis Presley's megacolon, which ultimately caused his demise. She also fleshes out just what constitutes the "ick factor" in this tale of ingestion, digestion and elimination. Roach's abundant footnotes serve as entertaining detours throughout this edifying excursion. When a topic heads toward sketchy territory, the author politely provides a heads-up for squeamish readers. Whether Roach is writing about lateral tongue protrusion, the taboo surrounding saliva or whether "rectal consumption of beef broth breaks one's Lenten fast," the author entertains with this incredible journey into the netherworld of the human body. A touchy topic illuminated with wit and rigor, packed with all the stinky details.
