can ice help with spicy food?
No.

The chemical action of capsaicin (the compound that triggers the burning sensation) is an effect on chemical receptors in your taste buds. It's perceived to a degree as temperature but it's entirely independent, so making your mouth colder wouldn't help.

The only way cold would minimize a spice burn is if you made your tongue/mouth cold enough to freeze, numb, and damage your taste buds, which would be a really bad idea.

Ice won't really help relieve the burn after you start feeling the spice either, because capsaicin isn't water-soluble. Here are some better suggestions for relief.
