In brief: Lots of Reasons

Cravings, especially for minerals, are not completely understood.
There is a prevailing theory that cravings for things like salt may indicate a deficiency in trace minerals (like manganese or selenium) which are found in salt deposits. Cravings are also sometimes associated with anemia or low blood counts. Or it could mean something as simple as you like the taste of salt...
