Eating corn in moderation does not usually cause indigestion; eating large quantities of corn may cause indigestion. Indigestion is caused by the presence of gastric dysfunction and is often characterized by epigastric pain, bloating and belching (burping). After eating food with indigestion, the food cannot be pushed downward in time and accumulates in the stomach, where it continues to ferment and produce gas, which in turn leads to the above symptoms. Corn is rich in vitamins, proteins, dietary fiber, calcium and other nutrients, which can promote peristalsis. It is recommended that you should usually eat some food rich in dietary fiber, such as corn, celery, etc., which is conducive to stimulating intestinal peristalsis. Therefore, eating corn in moderation generally does not cause indigestion, but if a large amount of corn is eaten at one time, it exceeds the limit of the gastrointestinal tract’s digestive and absorptive functions, which may lead to indigestion. Corn as a food, does not have the treatment of indigestion and other effects and functions, can not play the same role as drugs.
