Apples are relatively well digested, and if you have stomach problems, you can also experience indigestion if you eat too much at once. Apples are rich in vitamin C, malic acid, fructose, crude fiber, etc. These ingredients can promote gastrointestinal peristalsis, promote food digestion, so apples themselves are relatively easy to digest. If you have stomach problems, such as gastritis and gastric ulcers, eating too many apples at one time can also cause indigestion. People with stomach problems may have slowed gastrointestinal motility, and eating too many apples can stimulate the secretion of gastric acid, aggravating gastritis and gastric ulcers, so these people need to eat a moderate amount of apples. It is recommended to consult a doctor in time, under the guidance of a professional physician.
