Extended data:
The best fruit.
1, the most antioxidant
In addition to the basic nutrients, fruits also provide another beneficial substance-polyphenols, especially procyanidins, which have a strong antioxidant effect. In the process of energy metabolism, cells produce by-products-free radicals, which have oxidation and can destroy cell membranes, nucleic acids and so on. It is one of the important causes of chronic diseases such as human aging, gene mutation, inflammation and arteriosclerosis.
Procyanidins, vitamin E, carotene and other substances have strong antioxidant effect and can scavenge free radicals. People can improve immunity, reduce inflammation and prevent chronic diseases by taking these antioxidants every day. The darker the fruit is, the more proanthocyanidins it contains.
Blueberries, mulberries, cherries, strawberries, grapes, pomegranates and other purple or crimson fruits are rich in proanthocyanidins. Red and yellow fruits, such as mango, citrus, cantaloupe, papaya, watermelon, apricot, fresh jujube and persimmon, are rich in carotene and have good antioxidant effect, although they contain little proanthocyanidins.
2, dimension C is the highest
Vitamin C is one of the most needed nutrients for human body. It has many physiological functions, such as anti-oxidation, enhancing human immunity and improving the utilization rate of iron, calcium and folic acid. For infants, the elderly and people with low vegetable intake, fruits are the main source of vitamin C. However, many common fruits, such as bananas, apples, pears, peaches and watermelons, have low vitamin C content (< 10 mg/100 g).
Citrus, grapes, mangoes, pineapples, cantaloupes and other fruits have higher vitamin C content (10 ~ 30mg/ 100g). A few fruits, such as fresh jujube, kiwi fruit, strawberry, papaya and litchi, have higher vitamin C content (> 40mg/ 100g).
Among them, the vitamin C content of fresh jujube is far ahead, which is 243 mg/100 g, but it is worth noting that dried jujube loses a lot of vitamin C during drying, and its content is only 14 mg/100 g.
