Food and drink is taken in every day. It’s not surprising some of us snack around while we play.
what do you like to eat or drink to keep your tummy happy in between deaths or games while you play?
for me, Drinks i like to drink are energy drinks or soda for caffeine. for eats, sometimes things that you can mainly grab without getting food on your keyboard, or things in a bowl like pasta.
I just take a candy/gum.
Eating or drinking is too distracting imo.
Soda, Milkshakes, cotton candy, M&Ms, Popcorn, Goldfish Crackers, Hersey Chocolate, and Jerky just to name a few.
Mountain Dew and Doritos, the D.Va diet.
I drink water and occasionally eat some gummies. 
I drink water, and on weekends I’ll have coffee.
I’m trying to avoid having snacks at my desk anymore but one of my favorites is a Salty Pub Mix, which is mostly just tasty pretzels and peanuts. Goldfish are pretty great too.
Coffee and/or Diet Pepsi.
Strawberry pop-tarts.
It depends what you like, what your gaming situation is and what you are allergic to.
If you are in a casual mood, I may suggest either some chewy candies or hard candies that you can suck on, I enjoy sour candies because that give me a small rush of energy from the sour taste, or you may enjoy some chips, but if you do this, keep some wipes nearby so you can clean your fingers off from either flavoring or from crumbs and grease. In a more serious mood? Have some fruit near by, maybe pre cut so you can just pop it into your mouth, if you are sitting in for a long gaming session, have a small meal, like a burger, sandwich or burrito, just something small and not to difficult to eat with one free hand or something.
For drinks, again , you have choices of juices, pops (soft drinks, coke, colas, fountain drinks, soda, or whatever you call it where you are from), alcohol for the more older gamers (though I recommend this more for solo gaming than multiplayer gaming, because it could impede your reflexes and reaction time and attitude) coffee, or what for those just wanting something nice and cool and easy to clean.
Any questions?
