Prunes or dried plums
Prunes are a good source of dietary fiber, along with the components sorbitol and isatin, which help in regulating the colon. According to research studies, dried plums or prunes are more effective in treating digestive disorders such as constipation and colon issues. Sorbitol and isatin have a laxative effect and encourage the secretion of fluids in the bowels and promote the efficient flushing of waste through the colon.
