"If you are constipated, you can eat celery, leeks, bananas, nuts, yogurt and other foods to help excrete stool. Celery and leek are common crude fiber vegetables. Crude fiber will not only be absorbed by the intestinal system, but also absorb a lot of water. Therefore, it has the function of lubricating the intestine and stimulating intestinal peristalsis. Proper intake of this kind of food is helpful to the discharge of stool. Bananas are not only rich in dietary fiber, but also rich in B vitamins. Eating bananas properly can promote intestinal peristalsis, help the brain produce 5- hydroxytryptamine, prevent depression, and help the intestine excrete feces. Nut foods contain a lot of unsaturated fatty acids, which can lubricate the intestines when eaten properly.
