I've found that having plenty of fruit on hand is key to being able to work long startup days without feeling like crap at the end of the week. Non-perishables are somewhat overrated: most food will be eaten (especially once you know what people like and what they don't like), and having a few dollars' worth of fruit go bad each week is a tiny amount of your food budget.
