Exactly this. It's mind-blowing what kind of questions my well-educated ask about being a vegetarian. "Where do you get proteins from?" or "What about iron?". Really?!

The only real thing missing is B12 and of that the body needs so tiny amounts that every idiot can supplement it easily.

Not a vegan but B12 is easy to get (I have Crohns and B12 deficiency is fairly common), 1 energy drink is ~250% of RDA (They are stuffed with it).
