People with hyperacidity are suitable to eat light, low-sugar and low-fat foods as well as alkaline foods. Hyperacidity generally refers to excessive secretion of hydrochloric acid in the gastric juice. Excessive secretion of gastric acid will injure the gastric mucosa and duodenal mucosa, resulting in diseases such as duodenal ulcers and triggering uncomfortable symptoms such as burning sensation of the stomach, belching, regurgitation and vomiting of acidic water. Food has no therapeutic effect on people with hyperacidity, but only ensures the nutrition that patients need on a daily basis. Patients can make corresponding adjustments to the dietary structure, regular meals, diet should be light, low sugar and low fat, avoid spicy and stimulating foods. Such as noodles, lotus root, cabbage, bananas, coconut and so on. Eating alkaline foods can also properly neutralize stomach acid, such as persimmons, carrots, figs and so on. In addition to dietary requirements, patients should go to the hospital in time to receive examination and treatment, and then follow the doctor’s instructions to standardize the diagnosis and treatment when they have excessive gastric acid triggering uncomfortable symptoms.
