BEEF -> CANCER. PRETTY SIMPLE, NO?

"Big study links red meat diet to cancer," trumpets the Guardian. "International scientists yesterday delivered a long-awaited verdict on red meat, concluding in a definitive study of the eating habits of half a million people that beef, lamb, pork, veal and their processed varieties such as ham and bacon, increase the risk of bowel cancer." This is no surprise, but if this is a definitive study, can we stop acting surprised when the next cancer is "definitively" linked to red meat? And can we also stop pretending that diet gurus who push this deadly cancer risk on ill-informed consumers under the guise of "low-carb" are just harmless trendmongers?
