If you're thinking about a period without power after a disaster, you're supposed to have a gallon of clean water per person per day, along with food that can be prepared in that environment. At least according to https://www.ready.gov/kit.

For me, it made a ton of sense to buy a couple of boxes of MREs and some Mountain House meals for this. They last decades, and they double as camping food.
