Are cherries likely to cause or to relieve constipation?
— H.B. ANSWER: I can’t imagine that cherries are constipating, but I can imagine that they promote regularity. One cup of cherries has more than 3 grams of dietary fiber. Fiber is often a solution for constipation. I don’t know why your cherry experiment failed you. How about trying prunes? Five to eight prunes a day puts most people’s digestive tracts back to work. Not only do they provide fiber, but they contain sorbitol and phenols, substances that stimulate bowel movements. Don’t expect immediate results. Give them at least a three-week trial. If prunes don’t work, then get some Metamucil or Fiberall, commercial sources of fiber. If that fails, then begin use of a stool softener, like Colace. Walking right after breakfast and drinking more than your accustomed amount of fluids also get things working.
