I think it can be either healthy or unhealthy, but I have seen plenty of vegetarians eating what I would consider extremely unbalanced meals -- as in, I love squash, so I'll just have squash for dinner, or something. No real attempt to get proteins in there, a variety of vitamins, etc. Meat-eater might be more likely to have balanced meals, if only by accident, if you take people's tendencies to be dumb and lazy into account.
