Constipation

When ingested, raisins swell because the fiber present in has shrunk in a raisin s dried form, but it will begin to swell due to the body s natural fluids. This adds bulk to the food moving through the intestinal tract and ultimately helps provide relief from constipation. The type of fiber in raisins is considered insoluble fiber, because it takes in water and gains volume in that way. Besides reducing constipation, raisins can also help to stop loose stools, again by absorbing the liquid of loose stools and reducing the frequency and unpredictability of diarrhea.
