Shucks Mahoney’s #CBRV Review #49: Gulp by Mary Roach

gulp-9781851689934Tripping the light fantastic down the alimentary canal, right through from soup to, er, nuts, Mary Roach continues her run of popular science writing that yuks it up. Sometimes yuck. The squick factor is high with this one.

Roach points out that we don’t know a helluva lot about the digestive system, although pseudoscience abounds. Just today, I stumbled across a yoga magazine article arguing that raw foods contain more nutrients, fercrissakes. She jumps around from the magic of saliva, to Elvis’s super colon – poor old King – and the various crank cures for cleansing/improving/speeding up your plumbing equipment. There’s enemas with holy water and a brief but fascinating excursion up in to the prison economy fuelled by ‘hooping’ i.e. smuggling contraband in using the backdoor.

I loved two of her previous books, Stiff and Bonk, but I found this a more erratic in tone and harder to warm up to. Part of Roach’s schtick is quick comic sketches of her subjects, but sometimes these fall flat – and why does every single female she interviews get described by her level of attractiveness? That clangs. I was also driven to distraction by her wavering empathy levels. She’s touched by the plight of animal test subjects, but is incredibly callous when it comes to discussing human drug mules or people stricken by eating disorders.

The book is strong on interesting trivia and I certainly learned more about what happens to my daily victuals. I’ve been merrily grossing out friends and acquaintances with my new-found knowledge, and would recommend it as a decent introduction to the subject.
