Canned foods are the easiest way to start to build a food reserve- just double what you usually purchase. One caveat regarding this method- You will have a generally safe shelf life of only two-three years (there are exceptions to this, I know). This makes it very import to keep track of the expiration dates, and cycle them into your regular usage as they get close.

The second method (especially good if you don't want to maintain records of your shelf lives) is to purchase freeze-dried foods from reliable sources. Oregon Freeze-Dry has been making freeze-dried foods for about fifty years now, and are the leader in safety, nutrition, and longevity. Sold as "Mountain House" brand, these items generally have a ten to twenty year shelf life, great for "buy and forget"

Be wary of off-brand stored foods- many of these have high moisture content and unrealistic marked shelf lives.
