And they also use dextro amino acids, which makes it hard for them to eat food with levo proteins in it."
"That's not how it works, Taylor," Amy replied, looking somewhat lost. "Humans can eat either with pretty much no trouble at all. I mean, you might not get much in the way of certain essential nutrients from entirely dextro-amino food, but it won't kill you unless you do it for years and end up with malnutrition. Most of it will just go right through you. Might give you the runs but that's about it."
Taylor shrugged. "What can I say? That's apparently how it works for her species. Maybe they're not as well designed as we are."
