Insoluble non-starch polysaccharides (specifically cellulose and hemicellulose) act as effective laxatives by providing bulk to gut contents, promoting normal laxation and preventing constipation.

If you struggle with constipation, increase your intake of insoluble fiber found in whole grains, wheat bran, and the skins of fruits and vegetables. This adds bulk to your stool and helps move waste through your digestive system more effectively.
