When it comes to gaming snacks, I like to keep it simple with some salty snacks and a cold beverage to wash it down. But honestly, anything that can be eaten with one hand and won't leave a greasy residue on my controller works for me!
Popcorn gets stuck in your teeth. From the sharp chips burning in the stomach. So simple potato chips or sliced vegetables like cucumber and bell pepper are most suitable for me
I want to say it's one to one, but in all honesty I'm a bit fuzzy there. I can recommend JoyFreak's sister site AdminIntel - Admin & Webmaster Resource where there are lots for people of varying degrees of expertise with development, you likely can get a far more precise answer there!
