Although persimmons contain a lot of vitamins and pectin, they can play a role in detoxifying and nourishing the skin, moistening the lungs, enhancing appetite, lowering blood pressure, promoting gastrointestinal digestion, and replenishing vitamins. It is not appropriate to eat persimmons before going to bed at night; they should be eaten after meals and not in excess. When eating on an empty stomach, the stomach will secrete a lot of stomach acid, and persimmons contain more pectic acid and other substances, which combine with stomach acid and react easily to form a clot, which is usually called a stomach stone. When they are relatively small, they can be discharged with feces; when they are large and cannot be discharged, they can cause stomach pain, bloating, heartburn, acid reflux, vomiting, nausea and other symptoms, and can even cause gastric erosion and bleeding perforation. If you eat after a meal, the stomach acid has been combined with food, so it is relatively safe to eat persimmons at this time.
