Strange way to word the two patient types: vegans as opposed to omnivores. Vegans are still omnivores, they just stopped eating animal products because of beliefs.

I also smelled once a vegan cake. It's a medical miracle they can survive on such a diet.

> Vegans are still omnivores,

No they aren't.

From New Oxford English Dictionary:

> omnivorous

> adjective (of an animal or person) feeding on a variety of food of both plant and animal origin.

Herbivores are reciprocal to omnivores. Vegans are not comparable to either. Vegans don't eat animals not because they can't, but because of their beliefs. The word vegan describes a belief, contrary to omnivore and herbivore that describe physiology.

A human may choose to walk on all fours because they're insane, but they will still be a biped.

[DanBC]

That's not how language works.
