A PairofSympathetics: The answer could be made VERY complicated but, just to sort-of give an overall picture: if you are jagged-up by the sympathetic system, you won't have much of an appetite unless you're a shark on the make (well, a shark is a Chondrichthyte so technically doesn't have a sympathetic nervous system....whatever...), but if you are calmed down parasympathetically your juices will flow, ready to eat.
