It would be interesting to see the stats of a country like India though, where you don't have confounders like vegetarianism often being a class signal like in the developed world. Although the more I look into it, the more I find that "vegetarian" is a pretty loose label there. What societies in the past have mainly been vegetarian? None except India seem to persist to this day. I hear the human race took a pretty big hit in the early agricultural era as far as life expectancy goes.
