Prune juice
Prunes are dried plums, and they are known very well for their high fiber content. If you want something liquid to drink, guess what? There is also prune juice, and people consume it because it has a laxative effect.
Prune juice is high in sorbitol, and this compound is perfect for increasing the water content in the stool, making it easier to pass, and this can help relieve constipation without using harsh laxatives.
However, you need to be careful because, besides all these great effects, the sorbitol in the prune juice can make some people feel gassy due to the fermentation. Generally, if you suffer from constipation, the mild side effects can’t outweigh the benefits of prune juice.
