People with a normal gastrointestinal tract can eat corn on an empty stomach, and this has no effect, while people with a delicate gastrointestinal tract should not eat corn on an empty stomach. Corn is a starchy food that is slow to digest, and for patients with a weak gastrointestinal tract, corn can cause increased secretion of gastric acid, resulting in acid reflux, belching, heartburn and other symptoms, so it is recommended that such people avoid eating corn on an empty stomach. Corn itself is rich in vitamins and various minerals, can be eaten normally, it is best to cut off the cooked before eating, do not eat too much to give the gastrointestinal tract sufficient time to digest and absorb.
