Let me say right away that the environmental case against eating meat is well articulated, and I'm glad they managed to convey the importance of changing our diets to save the planet. Now, I would also have loved to see the vegan diet win! And when you start watching it, it sounds like it will! But, alas, it did not. The results of the study are inconclusive and very vaguely presented. Lots of sensationalism, little in the view of numbers. The study and the show are clearly biased from the get go - and yet they fail to make a compelling case for going vegan. I'm not even completely sure that this will help the cause. The vegan diet scores some wins, but the omnivore diet actually scores much better at times (e.g. The young African American twins). When this happens, it is brushed aside without much explanation. The angle of the whole show is not very scientific, and the amount of data collected is definitely inadequate. Some of the tests are just laughable from a scientific point of view (see the "sexual arousal" test, or the "germ glow" test). To be perfectly honest, at times it felt like paid advertisement for those vegan products. The environmental case against meat eating comes out much stronger than the dietary one.
