I know, I know, you're supposed to get away from your terminal and eat in the other room. But I never do.
I either a. eat a meal while surfing or b. munch on something while coding. It's the munching while coding that I've never been able to do "mindfully".
The best coding munchies are almost always the worst things to eat, like microwave popcorn, chips, cookies, and soda. When you're 4 levels deep into a nested routine, who notices that the munchies are gone? I suppose I could eat fresh fruit or something like that, but honestly, has anyone ever gotten into the "coding zone" eating grapes?
