I am always puzzled by the popularity of freeze-dried foods, whether in cans or in smaller packets, for "survival." The point of freeze drying is to reduce weight, a huge virtue for many outdoor uses like backpacking or climbing, in environments where water is reasonably common or abundant. When potable water is lacking, freeze dried products are at a disadvantage.
I do have FD foods stocked because I still backpack, etc. but for just plain old domestic disasters I lay in canned goods right from the supermarket. They are cheap, nutritious, easy to prepare (right out of the can, if necessary, durable and heavy, because they contain water, an advantage in many circumstances. The right canned products are essentially civilian MREs, but much cheaper
FD products are really great in the right environment, which is not the typical disaster situation where potable water will usually be scarce.
My strategy for disaster eating is to eat perishable goods first (ice cream!!) and then turn to more durable items as time goes on.
To me long storage is important, as keeping a stock of canned food and rotating it is a bit of an issue, as I rarely use canned food. (tomato puree and beans are pretty much the only things I get in cans).
Fresh food does not store long enough for emergency's; so freeze dried or other 20+ year food is a simple buy once and not think about it for 2 decades solution. Bit expensive, but lack of required logistics is also great. Although the new NG-5 are also rated 20 years.
