Which fruits contain more vitamin c

Whenever vitamin C was mentioned, many friends couldn't help but think of fruit. Some people even thought that as long as they often eat fruit, they would not lack vitamin C. In fact, this view is one-sided. Some of the fruits are rich in vitamin C, and some have little vitamin C content. According to statistics, kiwi, jujube, strawberry, wolfberry, orange, tangerine, and persimmon are rich in vitamin C. Calculated with the content of vitamin C in 100 grams of fruit, kiwifruit contains 420 mg, fresh dates contain 380 mg, strawberries contain 80 mg, orange contains 49 mg, loquat contains 36 mg, and oranges and persimmons contain 30 mg each. Bananas and peaches each contain 10 milligrams, grapes, figs and apples have only 5 milligrams each, and pears only contain 4 milligrams.

It has been determined that adults need 60 mg of vitamin C a day. If they are to be taken from fruits with low vitamin C content, 25 figs are needed, 14 are needed for pears, and 1.5 kg are needed for grapes. Therefore, eating only one or two fruits with low vitamin C content does not actually help. However, if it is a kiwi, citrus or persimmon with high vitamin C, one or two a day is enough. If fresh dates or strawberries, as long as five or six grains, you can take vitamin C needed for a day. Therefore, if you want to add enough vitamin C, you should have a choice when eating fruit.

In addition, there are some factors that affect the vitamin C content in fruits. For example, in order to prevent pests and sun exposure, some fruits are often wrapped in paper bags during the growth process. As a result, vitamin C content is reduced. In summer, fruit is harvested and stored in cold storage. When sold in winter, the vitamin C content of fruits is also reduced. Modern family There are refrigerators, and many people like to buy a lot of fruit. However, the longer the fruit is stored, the more vitamin C is lost.

It is worth mentioning that although some people have eaten many vitamin C-rich fruits, there are habits of smoking, because smoking can hinder the body's absorption of vitamin C, nicotine in tobacco has a destructive effect on vitamin C, so , It is also easy to lack of vitamin C; people engaged in intense exercise or heavy physical work, due to sweating will also lose a lot of vitamin C; there are some diseases and drugs will also affect the absorption of vitamin C. Therefore, fruit can not be used as the only source of vitamin C in the human body. If necessary, vitamin C tablets should be added.
