Eating persimmons before going to bed is not appropriate, persimmons should be put into the meal to eat, and can not eat more. When eating on an empty stomach, the stomach will secrete a lot of gastric acid, and persimmons contain more tannins, pectin and other substances, these substances and gastric acid combination reaction is easy to form a clot, which is usually called the stomach stone. When the clot is small, it can be discharged with the feces, when the stomach stone is large and can not be discharged, it can cause stomach pain, bloating, heartburn, acid reflux, nausea, vomiting and other symptoms, and can even cause gastric erosion, hemorrhage, perforation and so on. If put to eat after meals, stomach acid has been neutralized by food, this time to eat persimmons will be relatively much safer.
