I think it would be quite useful, if you could get an additional inventory upgrade like the medikit just for food and drink.
Maybe a lunchbox where you can store 1 food can and 1 soda can.

Nice idea...i mean right to the pistol there could be a food sign...
3 place for soda cans and 3 for food cans...
Or you could let them carry those around in a belt findable which you can see at your own body...
You just look down and see:
Oh 2 cans of pepsi and 1 can of pasta... i need more food

that's interesting. Like a small bag. They could turn the Czech vest pouch into it, in a smaller version.
