Do you think that, to aliens, we humans are like the supreme omnivores of the universe?

I mean, honestly, one of the greatest advantages we have as a species is our willingness to eat, or at least try to eat, just about anything.

Allergies, cultural differences, preferred diets, and intolerances, and general tastes for flavors aside, the average human is capable of finding a way to consume most anything we can get in our mouth.

Meat? Boom. Vegetables? Pretty good. Fruits? Love it. Bugs? Hey if we had to. Fish? Hell yeah. Eggs? Yeah man. Organs? Sure thing. Milk, honey, and food products made in other creatures? Classic.

Hell, if something isn’t immediately poisonous or just disgusting tasting, or even just flat undigestable, chances are a human can and will eat it.

Honestly, even if something is known to be poisonous (i.e. pufferfish), we’re not gonna rest until we find some part of it that’s not poisonous so we can eat that.

Some humans even will eat disgusting things, either to prove they can, or because they’ve found a way to make it palatable just so that they can actually eat it.

Especially consider that if other alien species we encounter are either flat herbivores or obligate carnivores. It might be to the concern of some newer crew members just how much the humans on board eat and what variety they will consume if given the chance; especially if they’re concerned about food rations being low. Or if they get to an unexplored world and the human is commenting about strange flora and fauna they find and comment how much it resembles foodstuffs on their home planet. Until they realize the humans are saying it about a LOT of the stuff on this unexplored world. To the point they’re worried that either the humans will eat something that would get them sick/poisoned, or they’ll end up just completely devouring anything and everything they see on the planet like a swarm of starved locusts.
