I more-or-less agree, food science is pretty fickle and it's just one study in one country. Edit: regarding the video, it's obviously a rebuttal from someone with a clear vested interest, but he brings up a few good points. I don't appreciate him saying or implying that the study's authors are saying 'vegetarianism causes disease' - because they're not. Very useful to hear from the other-side. If you really want to know more, you're going to have to do more in-depth research.
