WHERE DO YOU GET YOUR... CANCER?

"High Protein Diets May Boost Cancer Risk" blares the Washington Post, summarizing what looks like a pretty preliminary study, but one that merits at least as much hyping as any of the tiny preliminary studies that seemed to exonerate high-protein diets. Basically, the study found that physically fit people who consumed more protein (which, though it's not explicit here, is almost certainly mostly animal protein) had more IGF-I, known to spur the growth of cancer cells, as compared to those eating a lower-protein vegetarian diet. This should be followed up with more comprehensive studies, but for now it's worth noting that the old saw "where do you get your protein?" has never looked more dangerously inane.
