Why Do Prunes Make You Poop And Not Plums?
Prunes have higher fiber content than plums, and they also contain a natural laxative compound called sorbitol. This combination of fiber and sorbitol helps to stimulate the digestive tract and promote bowel movements, making prunes more effective in relieving constipation and making you poop. Plums also have fiber, but not as much as prunes, and they do not contain sorbitol in the same quantities.
