I have teeth of an omnivore, an alimentary canal of an omnivore, digestive enzymes of an omnivore, and dietary needs of an omnivore.
So do vegans. They may choose to eat like herbivores, but they are still omnivores.
Plants are difficult to digest. Some herbivores have several stomachs and ferment their food before swallowing, some eat their own feces to run the food through a second time, and some have extraordinarily long alimentary canals so the food stays in the digestive juices for a long time. I have one stomach, a short alimentary canal, and I am not about to eat my own feces.
I figure that for optimum health, I should honor my body and be an omnivore.
There are 7 nutrients that vegans cannot get

I don't think a vegan diet is a healthy diet. What I'm doing is working fine for me. I'm 75 years old, on zero prescriptions, almost never get sick (I think I've had one short cold in the last 15 years), and a heart doctor said I have a circulatory system of a healthy 50 year old.
I am a picky eater. Low carb, high fat, moderate protein. There are a lot of foods that fit my WOE but I simply do not like the taste of, so I avoid them.
I have no problems with vegans or vegetarians, unless they are militant or proselytizing about it. They are just being picky eaters too.
My wife and I have a couple of good friends who are vegans, and when we go out to eat, we choose a restaurant where we can all get something we like. I've never asked them why they are vegans, and I don't care.
Do unto others. I don't try to force my diet on anyone else, don't try to force your diet on me.
