What the fuck? No. Are you seriously asking that or is that sarcasm? It's so ridiculous it must be... I can't tell though.
Humans are herbivorous; that means we survive well off of just plant foods. Carnivores need to eat meat. I guess you could classify us as omnivorous as well, except our digestive tracts and such don't do well with meat.
I've been a vegan for 9 years, I am very healthy, I look healthy, my cheeks are always pink and I have a full head of hair. I eat a balanced diet, are you going to tell me that I'm wrong?
edit: Cereal is not a non-plant food you stooge, it's made from grains. Okay you must have been joking, I am a moron.
