Prunes are a good source of both insoluble and soluble fiber. Insoluble fiber helps to ease constipation and keep your bowel movements regular, while soluble fiber helps to moderate digestion and absorb nutrients from your food. Dried plums also contain sorbitol and chlorogenic acid, which can increase stool frequency.

Eating prunes, or dried plums, can alleviate constipation. According to a study in Critical Reviews in Food Science and Nutrition, dried plums and their derivatives, such as prune juice, can prevent constipation and may prevent colon cancer. The nutrients found in prunes may also help control obesity, diabetes, and cardiovascular diseases.
