One of the reasons junk food is so much cheaper is how it's preserved. Look at canned tuna or salmon compared to fresh fillets, it's preserved, it will hold its value longer. We are really in uncharted territory here, it's only within the last few centuries that we have been able to purchase food that can stay "good" for a nearly indefinite period of time. It's so much cheaper to can something, or freeze something than it is to sell it fresh.
