It won't actually hurt her. She just...won't digest it as easily as she would if it weren't the new moon. If she ate the whole bowl there would probably be a problem, but a few sips won't hurt her.

Unless, of course, she dumps it on herself trying to hold the damned thing. Which was exactly what would happen if Spirit had let her take the mug for herself. She might not be shivering, but she was as weak as Gladio's nickname for her. Still, she couldn't exactly eat while leaning against someone's side, so she shifted to sit on her own, wobbling a bit but managing it.

For the most part.

"Why are you being so nice to me?"
