Arguably more so because Judaism never advocated vegetarianism when that, of course, is one of the most radical commitments in terms of shaping a person's lifestyle that a religion could come up with (and a big reason why the Manichean faith isn't around today).
That's not quite true. While vegetarianism was never made a tenet of the faith (not surprising for a faith which had its origins among nomadic herdsmen) it is clear that a vegetarian diet was thought highly of. It is after all, the original diet in Eden and the prophet Daniel asked for and thrived on a vegetarian diet in Daniel 1. While Daniel did not remain a vegetarian, it was while on a fast that excluded rich foods such as meat that he had the vision of the kings of north and south in Daniel 10-12.
