Everyone knows that eating fruits is good for health, so fruits have become a regular meal for some people. In fact, some fruits are not suitable to be eaten on an empty stomach. Tomatoes: They contain a large amount of pectin, persimmon phenol, soluble astringents and other components, which are prone to chemical reactions with gastric acid and coagulate into insoluble lumps. These hard lumps can block the exit of the stomach - the pylorus, increase the pressure inside the stomach, cause the stomach to dilate and make people feel bloated and painful. Persimmon: It contains substances such as persimmon tannin, pectin, tannic acid and ellagin, and has a strong astringent effect. When the stomach is empty and encounters strong gastric acid, it is prone to combine with gastric acid and form hard lumps that are difficult to dissolve. Small hard lumps can be excreted with feces. If they form large hard lumps, it is easy to cause "gastric persimmon stone syndrome", which is called "persimmon stone syndrome" in traditional Chinese medicine. Bananas: They are rich in magnesium. If you eat a large amount of bananas on an empty stomach, the magnesium content in your blood will suddenly increase, causing an imbalance in the ratio of magnesium to calcium in your blood and exerting an inhibitory effect on the cardiovascular system, which is not good for your health. Oranges: Oranges contain a large amount of sugar and organic acids. Eating oranges on an empty stomach can irritate the gastric mucosa. Sugarcane and fresh lychees: When eating sugarcane or fresh lychees on an empty stomach, do not consume too much. Otherwise, "hyperosmolar coma" may occur due to the sudden influx of excessive high sugar into the body. Hawthorn: The sour taste of hawthorn has the effect of promoting qi circulation and aiding digestion. However, if eaten on an empty stomach, it not only consumes qi but also increases hunger and aggravates stomach problems. (Reposted online
