Canned goods last way longer then most people have been taught. Not too long ago (some years) the FDA changed their guidelines to match the reality of food processing. This quote is from the FDA Before You Toss Food, Wait. Check It Out! blog.
“What about the foods in your pantry? Most shelf-stable foods are safe indefinitely. In fact, canned goods will last for years, as long as the can itself is in good condition (no rust, dents, or swelling). Packaged foods (cereal, pasta, cookies) will be safe past the ‘best by’ date, although they may eventually become stale or develop an off flavor. You'll know when you open the package if the food has lost quality. Many dates on foods refer to quality, not safety.

MOST canned goods last a long time.

Highly acidic ones can destroy the can in a few years. Those are better kept in glass. And yes, glass can break, but NO method of food storage is without it’s downside.

If you look at the date on boxes of pasta, for example, the best buy or expiration date is YEARS out. Those I out in 2 qt canning jars and vacuum seal for protection against infestation.
