Unripe fruits are not suitable for eating. Some people taste sour, so when eating fruits, they like to choose some immature fruits. As everyone knows, this practice is harmful to health. This is because most immature fruits contain oxalic acid and benzoic acid and other components, which are difficult to oxidize and decompose in the human body. The products after metabolism are still acidic, which will destroy the normal weak alkaline environment of the human body and cause physiological Functional impact. In addition, some fruits such as bananas and apricots contain toxins when they are immature, which is also harmful to the human body. Therefore, it is not advisable to eat unripe fruits.

　　Eating fruit requires peeling. Many people don''t even peel their skin when they eat fruit, so wash and eat. In fact, eating fruits like this is very unhygienic. In order to prevent pests and diseases, fruit farmers often use a variety of pesticides during the growth of fruit trees. Some pesticides can soak and remain in the waxy layer of the peel, so the pesticide residue in the peel is much higher than that in the pulp. Moreover, these pesticides remaining in the peel are difficult to wash off with water. If you eat without peeling, for a long period of time, you will have vomiting, diarrhea, anorexia, chest tightness, skin allergies and other reactions, and it will damage the stomach and intestine and endanger your health. In addition, most fruits contain pathogenic microorganisms such as bacteria, viruses and parasitic eggs. If they are not cleaned thoroughly, they will cause diseases such as dysentery and ascariasis if they are eaten into the stomach.

　　After consuming fruit, gargle. Some people like to eat some fruits after meals, instead of gargle, to achieve the purpose of cleaning the mouth. In fact, there is no scientific basis. In fact, most fruits contain more sugar. These sugars and the fruit residues embedded in the teeth and gingival spaces will gradually ferment and become sour in the mouth. After a long time, they will corrode the teeth and easily form caries. And eventually produce holes. Therefore, eating fruits does not clean the mouth. On the contrary, after eating fruits, pay attention to gargle in order to remove the sugar in the mouth.
