I've always suspected my periodic craving for Vegemite is simply due to salt deficiency. Those that didn't grow up with Vegemite tend to find it disgusting but a craving for Vegemite is a well known thing in Australia where you can sweat out huge quantities of salt on a typical summers day.
These weird foods probably have concentrations of various things that you simply won't see in anywhere else. Salt appetite is a proven and understood phenomenon but i bet there's similar things going on in all of these foods. You try it once and probably don't like it then and there and then one day your brain brings up the memory of that food and tells you to go eat it again.
