were i you, and of a mind to lay in some food for that day when the shit hits the fan, i would go out and buy some good quality dry dog and/or cat food. purina or iams run to mind.
it has got corn and wheat and barley and such like that, and god only knows what else, but it is properly ground, steamed & kiln dried, and has a good shelf life. i am informed that most alaskan bush pilots have a 30 lb. bag of the stuff put away in a little corner in their planes, in case they have to get by in the bush until help arrives.
it cannot be too bad, not any worse than most cereals, i am thinking.

p.s. i also would consider, were i you, some canned meats, ... , corned beef, vienna sausage, and chili. it's got some protein, and lots of good basic fat. and, along that line, canned bacon would be a good bet, as well as a bunch of canned hams.
my friend chipps whipple was fond of quoting his father to the effect that "... hunger is the sauce of the poor man's fare." i always liked that. if somebody famous said it before chipps's dad, so be it, but i always shall attribute it to that source.
i never met the pater familias whipple, but, i expect that i would have liked him. chipps and russ are good people, and the old man must have been a pretty good block to have been chipped from, given his fondness for that basic truth.
and, the truth is, if you are hungry enough, some dried dog food and some vienna sausage are quite likely to be very tasty.
