Sure, you can find subsets of the population whose health depends on incorporating meat in their diet (that's what I meant with "healthy people", although I misworded it; people who need meat in their diet aren't necessarily unhealthy, their health is conditional on consuming meat). I accept that much. This argument is not very powerful though. For one, it only justifies eating meat for those who have tried to cut meat from their diet and noticed adverse health effects (which should be safe for most people who don't already suffer from some risk factor, like anemia, to try); in my anecdotal experience a tiny minority of the people who make health-based arguments. And secondly, it only justifies the minimal meat consumption necessary to be healthy, and no more.
