Insoluble fiber helps relieve constipation faster, and soluble fiber helps the digestive system stay regular when it is added to the daily diet, states Healthline. Water is beneficial because it helps prevent or moisten hard stool. Exercise or walking helps stimulate the digestive system and aids in moving waste through the body.
