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)
