Roy, do you need me to tell you about the dietary supplements vegans need to prevent several debilitating conditions? Why don't you google that for yourself? Yeah, vegan diets are healthy diets when those supplements are added. We already know that reducing meat consumption and increasing vegetable and fruit consumption results in better health. Congratulations. Also, vitamin B-12 is available only from animal sources or synthetically from chemical plants. Since there were no chemical plants before human civilization, we can rule out the possibility that humans evolved without eating animal food sources. I do love that argument over whether or not mussels and oysters actually qualify as "animals"--kind of like catholic explorers who declared capybaras to be fish so they could eat them on Fridays.

Nobody cares what you eat or don't eat, but the illusion that vegans or vegetarians are morally superior to omnivores is nothing more than a self-deluding fantasy. It is a religion.
