>If none of the stuff you normally like keeps, you are not eating right.
Not to be picky, but eating fresh fruit and vegetables means someone is not eating right? (Yes, of course you're not going to be able to find these in a disaster) For what it's worth, the shelf life of Chunky Soup is 1-2 years, maybe a bit longer if it's in a cold root cellar most of the time.
>Real survivalists stock MRE's
I'd argue that real survivalists stock dehydrated foods, dry beans, rice, wheat, yeast, cooking oil (watch the shelf life on this) and the like. These items allow for a much greater flexibility in preparation over a long period of time (shelf life can be 10 years+ pretty easily), and don't result in the digestive "features" of MREs. (Not to mention, MREs are outrageously expensive in comparison and shelf life is supposed to be 5-7 years) You definitely don't want to live on them. For a day or two if you absolutely positively can't find any water or fuel, OK, but if you don't have those, you have bigger problems anyway.
