Is anyone vegan or vegetarian for health reasons only? I finally met a vegan at a class I was taking. It was the first time I had actually met a vegan in the flesh and I was so excited to have someone to talk to about animal rights, diet, etc. Turns out he is vegan for health reasons only(he has no health problems, just doesn't want any). He is a runner and wants to eat a healthy diet for this reason. He has no concern for animals whatsoever. I am glad he is vegan for whatever reason because animals are spared, but I guess I always assumed that almost all vegans or vegetarians had animal welfare as one of the major reasons for their diet choice. I don't mean to sound critical of him, I was just surprised I guess! Is my assumption valid?
