People who have a bit of land might also consider learning how to vegetable garden and put food up. It would be of higher nutrition, have less additives, less salt, and still provide fiber (which isn't exciting, but you still need it).

And it probably isn't likely, but who knows? Maybe the dire situation will take place when the food is still in the garden, and you can eat it fresh!

You might also consider keeping a few chickens. Eggs are a high-quality protein, and they are often laid daily. Allowed to range through the yard, they will also find some food for themselves, making eggs out of grass and bugs.
