Food Storage--Shelf Life

I recently came across the iPrepared blog, which appears to be a handy blog for food storage. iPrepared has a couple articles on shelf life. First, she notes some recent research from BYU on the shelf-life of common food storage items. Second, she notes a recent study showing that the food expiration/sell by dates on most foods are not an accurate indicator of the maximum safe storage life--most foods are useable well past that date.
