You Are What You Eat,
This review is from: Gulp: Adventures on the Alimentary Canal (Paperback)
'Laundry detergent is essentially a digestive tract in a box.' Now, where else but in a book written by Mary Roach, the author who loves wierd science, would we learn such a thing? I mean, it makes sense, but I have never seen anyone write those words. In her new book, 'Gulp' etc, Mary Roach takes us from the mouth to the anus, and all the by-ways in-between. It is one of the more fascinating and informative books I have read in a long time. I am a health care practitioner, but I have learned more about our alimentary canal and the research involved in it's mysteries, than any of my Anatomy and Physiology books. There is so much to know and learn, I want to cover it all, but I won't, I will leave it to you to go on this journey.
"The human digestive track is like the Amtrak line from Seattle to Los Angeles; transit time is about thirty hours , and the scenery on the last lag is pretty monotonous". There you have it, from the first bite of food that is first smelled, chewed, oral digestive acids acted up on, moved down the esophagus to the stomach and into the bowels, large and small intestine and then into the anus, where the food that went in is expelled. The circuitous route taken is fascinating.
Chewing leads to a discussion of saliva, and we learn "Bodily fluids, gas and excrement may disgust us once they leave the body, but "we are large, mobile vessels of the very substances we find most repulsive." We learn a lot about 'gas', it's make-up, smell, testing, who makes the most gas, farting, and on and on. Megacolon, the large bowel dilatation that causes much straining to release it's contents and can cause cardiac arrhythmia and death, as it probably did for Elvis Presley. Mary Roach spent a great deal of time in her research for this book, traveling the world. Somehow she knew what questions to ask, who to meet, what experiments to take part in.
This really is one of the best books I have read this year. I am a mystery lover, and this book has uncovered mysteries I never knew existed.
"Most of us pass our lives never once laying eyes on our organs, the most precious and amazing things we own. Until something goes wrong, we barely give them thought. This seems strange to me. It is, of course, possible that I seem strange. You may be thinking, 'Wow, that Mary Roach has her head up her a**.' To which I say, 'Only briefly, and with the utmost respect!" Mary in her own words!
