The date found on canned goods is the "Best By" date. What this basically means is that if you eat it on or before that date it will have the best flavor and the actually nutritional value will be what is listed on the can's nutritional content label. The nutritional value is said to degrade over time in canned goods. To what degree can vary from product to product and depending on the method in which it was stored. Ideally, you want to store them a cool(60-75 degrees), dry place with limited exposure to direct sunlight(especially important with home canned goods in glass jars).
Avoid storing dented cans or ones that have rust present. Before opening, ensure that the cans are not bulged/swollen. This is an indication of spoilage and/or botchulism is present. Store items that you normally eat on a regular basis and always rotate them so that you are using the oldest stuff first. I've eaten canned goods that were ten years past the "Best By" date on the can. It wasn't the best tasting stuff in the world(a little metallic) though.
100% non-pasteurized raw honey stores indefinitely. Rice, beans, pasta, oats, sugar and salt all store well too. The trick is the same for the most part...... cool, dry, dark place. The absolute best way to store this stuff is in an air tight, non-translucent containers with as much as the oxygen removed as possible. FDA approved 5&6 gallon buckets w/ gasketed lids and mylar bags are usually the most common container/packaging methods found. While there are several different methods for removing the O2 content such as; O2 absorbers, dry ice, nitrogen purging, etc., etc. I personally prefer the O2 absorbers as they are quick, easy and the safest to use.
If you are really serious about getting into and using food storage, I highly recommend as a starting point getting a copy of Marlene's Magic w/ Food Storage Book. (

Not only does she give you a list of easily attainable ingredients to store, she gives numerous recipes to use them in for breakfast, lunch, dinner, snacks and desserts. Here are a couple of really good sites for finding some excellent freeze dried veggies and fruit, wheat( a whole other subject of it's own), powdered eggs, powdered milk, powdered cheese and much more.
