The different effects of these fruits have been scientifically summarized. Fruits with high Vc content, such as kiwi fruit, fresh jujube, strawberry, loquat, orange, orange and persimmon, are rich in vitamin C. Based on the vitamin C content of 100g fruit, kiwi fruit contains 420mg, fresh jujube contains 380mg, strawberry contains 80mg, orange contains 49mg, loquat contains 36mg, and orange and persimmon contain 30mg each. Bananas and peaches each contain 10 mg, grapes, figs and apples each contain only 5 mg, and pears only contain 4 mg. It is measured that adults need 60 mg of vitamin C every day. If they want to get vitamin C from fruits with little content, they need 25 figs, 14 pears, 1.5 Jin grapes. Therefore, eating only one or two fruits with low vitamin C content is actually not helpful. But if it is kiwifruit, citrus or persimmon with high vitamin C content, one or two a day is enough. If it is fresh dates or strawberries, you can get the vitamin C you need for a day by taking five or six tablets. Therefore, if you want to supplement enough vitamin C, you should be selective when eating fruits. In addition, there are some factors that affect the content of vitamin C in fruits. For example, some fruits are often packed in paper bags for insect prevention and sun protection, resulting in a decrease in vitamin C content; Fruits are harvested in summer and stored in cold storage. When sold in winter, the vitamin C content of fruits will also decrease. Modern families generally have refrigerators, and many people like to buy a lot of fruits and put them in. But the longer the fruit is stored, the more vitamin C is lost. Fruit is also a hidden danger. Some people mistakenly believe that fruit is nutritious and eating more is good for people. Actually, it is not. For example, apples contain sugar and potassium salt, which is not good for the heart. Patients with coronary heart disease, myocardial infarction, nephritis and diabetes should not eat more; Old people with citrus cold, gastrointestinal discomfort and kidney and lung insufficiency can't eat more; Pears contain a lot of sugar, and if diabetics eat too much, their blood sugar will rise. Persimmon contains tannin and persimmon gum phenol, so patients with poor gastrointestinal function or constipation should eat less, otherwise persimmon stones will easily form; Pineapple is rich in vitamins A, B, C, citric acid, protease and so on. And has the effects of promoting digestion, stopping diarrhea, lowering blood pressure and diuresis. However, some people with special physique will have intermittent abdominal pain and even vomiting after eating. It is best to soak the cut pineapple in salt water and then heat it. ] Why can fruit relieve hangover? Excessive drinking is often a symptom of drunkenness. There are many signs of drunkenness, more languages, ineffective tongue, fever and numbness in cheeks, dizziness, and unstable standing ... These are all signs of drunkenness. At this time, it is necessary to hangover. Many people know that eating some sour fruit or drinking 1-2 clean vinegar can relieve hangover. What is the truth? This is because fruits contain organic acids, for example, apples contain malic acid, oranges contain citric acid, and grapes contain tartaric acid. The main component of wine is ethanol, and organic acids can interact with ethanol to form esters to achieve the purpose of hangover. Similarly, vinegar can relieve alcoholism because it contains 3-5% acetic acid, which can react with ethanol to produce ethyl acetate. Although the fruit with sour taste and vinegar can reduce the anesthetic effect of excessive ethanol, the effect is not very ideal due to the interference of many factors when esterification is carried out in vivo. Therefore, the best way to prevent drunkenness is not to drink too much. Fruit can't replace vegetables. 2, 3-year-old children may not like vegetables, because vegetables are difficult to chew, and the taste is not very attractive to children. Therefore, some parents use fruits instead of vegetables. Fruits and vegetables have different compositions. The main components of fresh fruits are vitamin C, organic acids and inorganic salts, and a small amount of sugar, while fresh vegetables contain more vitamin C, minerals and cellulose than fruits. Cellulose can promote intestinal peristalsis and prevent constipation. Some vegetables contain some phytochemicals, which can fight cancer and prevent arteriosclerosis. Therefore, fruits and vegetables provide different nutrients and cannot replace each other.
