While store what you eat, eat what you store is very good advice and should cover 80% of your needs, you might have to look into can fruit if you normally eat fresh fruit...canned or dried meats if you normally eat frozen meets.
Three things to think of is lack or power for a fridge, lack of water supply (you will want to drink the god stuff and not wasting what little you have on long cook pasta only to pure the pasta water down the drain...and lack of power for cooking (though this can be worked around with camp stoves).
Also include throw away plates and forks/cups so you don't waste water cleaning your dishes if low water is part of the disaster.
