Eating prunes, or dried plums, can alleviate constipation. According to studies dried plums and their derivatives, such as prune juice, can prevent constipation and even possibly colon cancer. The nutrients found in prunes may also help control obesity, diabetes, and other cardiovascular diseases. 

Dried plums are considered to be very good for your overall health. Prune juice is filtered, so it doesn’t have the high fiber content of dried prunes. Still, both are laxatives because of their high sorbitol content. Dried plums also contain iron to help prevent anemia (they contain vitamin C + Iron), potassium that aids in healthy blood pressure, sugars combined with soluble fiber that provide sustained energy, phenolic compounds that can help prevent chronic diseases, and boron that can help prevent osteoporosis.

This super fruit I highly recommend to every pregnant lady here but make sure you don't eat them too much. You don't want to feel stomach sick suddenly ;)
