Sweet potato and banana are rich in starch, pectin and dietary fiber. Eating too much pectin together with dietary fiber can easily stimulate gastrointestinal peristalsis, increase the water content of feces and accelerate the abnormal discharge of feces. At the same time, eating too much starch in a short time is not only difficult to digest, but also prone to discomfort caused by excessive gastric acid secretion. Therefore, neither sweet potato nor banana is a good diet for healthy people.

Sweet potatoes and bananas are recommended to be eaten after 2-3 hours. Sweet potato is rich in starch and feels full after eating. It usually takes about 3 hours to digest and metabolize through the stomach. Bananas are fruits, most of which are easy to digest and can be metabolized after 2 hours. It is recommended to eat bananas or bananas after digestion to avoid discomfort.
