A large number of fruits are on the market in spring. Experts from the Municipal Nutrition Society remind that fruits such as persimmons, bananas, tomatoes, oranges, and hawthorns are not suitable for eating on an empty stomach. In the fasting state, the secretion of gastric acid will increase, and the concentration of gastric acid will also be higher. After eating a large amount of fruit, if the gastric acid combines with components such as gum, gum phenol, and soluble astringents in the fruit, it will become a precipitate that is difficult to dissolve. If the sediment forms into large pieces, it will cause various discomforts and digestive tract diseases. Tomatoes: It is easy to react with gastric acid and condense into lumps that are not easily dissolved, which can block the outlet of the stomach, increase the pressure in the stomach, and cause gastric bloating and pain. Persimmon: Contains persimmon phenol, pectin, tannic acid, tannin and other substances. It has a strong astringent effect. If eaten in large quantities on an empty stomach, it will encounter strong gastric acid when the stomach is empty, and it will easily combine with the gastric acid to form a substance that is difficult to dissolve. Hard lumps may cause "gastric persimmon stone disease", which is called "persimmon stone disease" in traditional Chinese medicine. Patients with gallstones and kidney stones should also be careful when eating persimmons to avoid worsening of the condition. Bananas: Contain a large amount of magnesium. Eating large amounts of bananas on an empty stomach will suddenly increase the magnesium content in the blood, which will have an inhibitory effect on the cardiovascular system, cause an imbalance in the ratio of magnesium and calcium in the blood, and irritate the gastric mucosa, which is detrimental to health. Oranges: Oranges contain a lot of sugar and organic acids. Eating oranges on an empty stomach will irritate the gastric mucosa. Hawthorn: The sour taste of hawthorn has the effect of promoting qi and digestion, but if eaten on an empty stomach, it will not only consume gas, but also increase hunger and aggravate stomach problems. Sugar cane and fresh lychees: Do not eat too much sugar cane or fresh lychees on an empty stomach, otherwise "hyperosmotic coma" may occur due to the sudden penetration of excessive amounts of sugar into the body.
