Andora... I think the term you're looking for is omnivore --- humans can't survive on a purely meat diet (aka carnivore)... plants can provide enough variety to cover most of our dietary needs hence why humans can be vegans (herbivores).
However it's easier (and possibly safer) to follow a more traditional omnivorous diet.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
