there aren't health benefits from being vegan vs being plant based.
the feeling of moral superiority or value signalling that vegan's enjoy is only possible until the vegan studies where their food comes from and how it is produced.
many people would become plant based or vegan if they had to kill their own livestock, chickens.
it's interesting the vegetarian who eats fish because they don't think the face has as much appeal as a duck or a pig :).
Main point: it's all how you decide to run your head space.
