Imagine aliens reacting to human eating habits.
For instance, taste. Like, one day an alien notices the human crew member dumping something bright orange on their midday ration.
Alien: Does your supplement not have the right nutrients/?
Human: No, it just tastes bad.
Human: Well, not precisely bad, but bland. It’s boring. So I thought I’d spice it up a bit. *waves bottle of bright orange substance*
Alien: You add items to your food that provide no necessary sustenance???
Human: Oh, just wait ‘til you hear about junk food.
‘Cause humans eat stuff that is not good just for the sensation. Like really spicy foods, chewing gum, and all these spices. And the aliens don’t get it. You put that in your body? Doesn’t that mess up your digestive system? What purpose does it serve?
Or human eating rituals. If you eat with one group of humans there are all of these utensils, some of which look extremely similar, but each with it’s own unique purpose. And if you don’t use the right one at the right time it’s a social faux pas. Then another group mostly uses their hands and lick their fingers. Does this not introduce pathogens? And you’ll see the same human doing both behaviors.
And there’s the whole concept of a meal as a social endeavor. Humans will have a meal with those they are close with as a sign of affection. Humans don’t even spend the entire meal eating, no they use it to talk. Business is done, friends catch up, families share news. All over a meal.
Aliens considering food a necessity not to be discussed in public. Yet here are these humans, who post pictures of their food to social media, share recipes, use food as a social catalyst, and as comfort. Hell, comfort food as a completely human idea that aliens don’t understand.
Anyway, humans are weird.
