There doesn't necessarily have to be a food shortage, but there will almost certainly be a shortage of processed foods. Which would describe the partially hydrogenate corn or soybean oil typically used in deep fat fryers.
One good example about future shortages is to look at the lifecycle of a pound of beef. It takes about 10 pounds of corn to produce 1 pound of beef. That corn gets its start in fields that have been fertilized by chemicals that are heavily dependent on petroleum. Consider all the energy required to run huge tractors, move all the feed from A to Z, move the steer from Z to X and you have just touched the surface of the problem.
Yet, despite all these facts, you can still grow carrots in your back yard. Farmers can supply healthy vegetables and meat products to local consumers without a lot of petroleum overhead.... but don't count on using the leftovers to fuel your trip to the mall.
