It turns out that medical education has a long and rich history of using food metaphors to describe body parts, diseases, symptoms, and everything else that students have to memorize. For instance, pus from a liver abscess looks a lot like anchovy sauce, and a particularly aggressive form of lung cancer is called "oat cell carcinoma" for its appearance under the microscope.
Dr. Ritu Lakhtakia, M.D., Ph.D., head of the Department of Pathology at the College of Medicine at Sultan Qaboos University, compiled these medical-foodie terms in a recently published article for the journal Medical Humanities in an effort to preserve a dying tradition. Because she herself was once a med student, toiling away to memorize facts and pictures, Lakhtakia has fond memories about how culinary imagery made study time a bit more fun.
"They make memorization of difficult facts child's play," said Lakhtakia about food metaphors in an email to the Huffington Post. "They also introduce medical graduates across the world to cuisines they are unfamiliar with."
For instance, one of the tell-tale symptoms of von Recklinghausen’s disease are cafe au lait marks on the skin. Certain fungal skin infections produce skin scrapes that look like spaghetti and meatballs under a microscope.
Unfortunately, said Lakhtakia, the tradition is dying away in favor of what she called "more direct (and less picturesque)" language. The metaphors are also becoming unnecessary because of technological advancement. Take, for example, the task of estimating tumor size.
"Long before scale measurements came into vogue, a three-dimensional estimate of the size of tumors could be easily documented by being compared with peanuts or walnuts (if larger, lemons or oranges come in handy for sizing!)," Lakhtakia wrote in the article.
Lakhtakia is not sure why food metaphors are so prevalent in medicine, but she guesses that the universality of food gave teachers a common base with students from which to explain difficult medical concepts. And of course, there is another reason: doctors and researchers eat while working.
"A part of this curious tradition may owe its origins to practising physicians and researchers catching up on their meals in clinical side rooms or operating theatre offices, or with an inevitably cold platter eaten with eyes glued to a microscope," she wrote in her article. "It is a wonder that, in the midst of the smells and sights of human affliction, a physician has the stomach to think of food at all!"
A wonder indeed. In honor of this quirky, stomach-churning medical tradition, Huffington Post's own Alissa Scheller whimsically illustrated just a few of the metaphors Lakhtakia included in her articles.
