Have you seen some of the stuff Amethyst has ate :3 Seeing as she technically doesn't need to in the first place, she'll eat anything without hesitation as she does so for fun.
For instance, she's eaten the burrito thing, a very disturbing "cake" that smelled awful, a teabag, an energy drink including the very can it was in, etc.
 The list goes on.
