Sun dried toms can have added salt, so be wary, other than that it's fine to eat when they're soaked in water.
Dried items are never as good as fresh, but they can add some fun variety on occasion. Tooth hygiene becomes particularly important because of the extra stickiness.
In addition to what the others have noted already, watch for added oil(!) in some brands of raisins, and look for those that are purely sun-dried without additional heating methods.
