4. Prunes
Prunes are an interesting option on this list because they are also very beneficial for improving the opposite of diarrhea: constipation!
That’s partly because prunes contain non-soluble fiber, which can be used in order to break up trapped stool. In this case, though, prunes may actually help to provide some much-needed bulk to your bowel movements.
At the same time, prunes can be useful because they contain sorbitol. This is a substance that absorbs fluid and which is beneficial for constipation because it helps to absorb fluid and add that to the stool. In the case of diarrhea, it helps to gather the moisture together in one place, making it a much healthier consistency to pass through your system and helping to speed up your recovery.
