This reads like an out and out lie to me. Water storage is basicly forever.
But all the end-of-the-world nuts and people who just want long term safety
incase of a major national problem have been buying freeze-dried, canned,
sealed and stored in extra cold freezer food that is rated for 5-7-even 10
years storage. And that is just goe average calling a local dealer.

A quick google search using 'long term food storage' gives me for example:

To me it sounds like some at NASA is fishing for more money instead of
storing dehydrated at low temperatures.
