Uh, of course? That's the stuff that keeps on the shelf. The point of disaster preparation is to avoid burning cash on throwing your food out every six months or hitting the expiry while you possibly don't even have running water if you forget when rotation day is. It's not a luxury athletics product; it's meant to keep you and your family supplied with calories for a week after an earthquake takes out the interstate your supermarket gets its deliveries on and there is no food to be had at any price. Do you have any actual experience with disaster planning? This comment is wildly off the mark.
