I’m a big fan of Mary Roach’s writing, and Gulp does not disappoint. Roach mixes hard science and humor in a way that is skilled enough to seem effortless. Here she tackles the taboo topic of digestion and its mysteries, a constant process from the mouth to the anus (and, for some animals, sometimes right back again.) This book is a fantastic reminder of how grateful we should be every day for our own working alimentary canal, even with its occasional flare-ups and embarrassments. Highly recommended for anyone who’s genuinely interested in the science of digestion.
