I think salt is an important historical resource that should be considered.
It would need to transition through history as to it's effects. Perhaps salt could double a health meat resoure like cows, pigs, fish, or sheep. It could also boost commerce +1 until granaries then +2 until currency then obsolete it's financial value. It could loose it's health bonus once you reach refrigeration technology.
Well on second thought maybe that's too big a bonus for salt. How about +1 health for every two resources that it preserves?
That being said I think civ 4 does a great job of providing a general realistic simulation.
