Having been through three hurricanes where power was off for several weeks (2004-2005) I became a realist when it comes to "survival food"
First, unless you have a years supply stored, you really do not have survival food, you have "shortage" supplies. If you are prepareing for post hurricane, flood, earthquake etc, you are likely planning max two weeks. If you are planning war or nuke, that is a whole different story that likely isn't going to work anyway. So I am talking about the first.
We were always taught MRE's, Freeze Dried, Peanut Butter, Tuna Fish, Canned Goods, etc, etc, etc. BULL! The three most important things if you plan to hunker down during a long term power outage (which is what we are really worried about in these instances) is WATER (we keep 12 cases of half-liter bottles), a small generator and some gasoline (or whatever fuel for it), and a gas grill or camp stove (and fuel).
Then keep your freezer full of meat.
If the power goes off, you can move the meet to the fridge to help keep it cold, you can cook the meat as it thaws to have real meals, and the remainder will stay frozen for days. Twice a day you need to power up the generator and run the fridge for a few hours. Every few days, run the freezer for a few hours. With a Honda 2000 watt generator, we used this routine to maintain refrigeration and unspoiled (albiet thawed in the end) food for two weeks on five gallons of gasoline.
In the end, after doing it three times, my MRE's (actually Mountain House) are still on the shelf, and we use the other stuff like normal still keeping a reasonable supply on hand. I am planning to move three days of MRE's to a "jump kit" with a water purifier and other esentials for the road because in an evacuation is where they would really be handy. (One does not evacuate for hurricanes in South Florida because it is too dangerous of getting caught on the road.)
If food for more than a few weeks is under consideration, I think more important would be ammo both for defense but more for hunting and a way to purify water, because if life is not back to relative normal (services available) after a month, it is not going to be for a long, long time and eating freeze dried for a year is just delaying the adjustment.
