Vitamin C is one of the most concerned nutrients. Because of its antioxidant effect, it has always been considered as a "powerful weapon" for anti-aging, anti-cancer, preventing colds and even fighting smog. In 20 16, the reporter surveyed more than 0/00 consumers and found that the recommendation rate of kiwifruit was the highest. More than 30% of consumers thought that kiwifruit in Faye Wong was vitamin C for fruits and vegetables.
In addition, the recommendation rate of oranges, cherries and lemons in fruits is close behind, and they are also considered to be fruits with high vitamin C content. Interestingly, among vegetables, the "king of vitamin C" recognized by ordinary people is very consistent, pointing directly at peppers and green peppers.
In this regard, the reporter consulted the revised version of China Food Composition Table 20 12, and found that the food with the highest vitamin C content in vegetables is indeed small red pepper, and the vitamin C content per 100 grams of food is 144 mg. In addition, Chinese kale, sweet pepper, pea seedling and cauliflower belong to the "second echelon", and the content of vitamin C per100g of food is 70 mg.
Among fruits, kiwi fruit is not low in vitamin C, but it is not the "king of vitamin C". The reporter found that the content of vitamin C in these foods, including guava, Chinese kiwi fruit and red fruit, is about 60 mg per 100 g, while fresh dates and wild jujubes are higher, with hundreds of mg of vitamin C per 100 g. The content of vitamin C in Rosa roxburghii was 2585 mg/100g.
Extended data
Li Ning, a nutritionist at Peking Union Medical College Hospital, pointed out that the content of vitamin C in fruits and vegetables can only be compared. There is no absolute relationship between ranking and the role of human health care. Researcher Zheng Jinxi also said that green pepper, alfalfa, Chinese kale, coriander, jujube, kiwi fruit, pomegranate, strawberry, hawthorn and citrus are all common fruits and vegetables with high vitamin C content.
Although Rosa roxburghii is a veritable "king of vitamin C", in fact, the daily intake of vitamin C required by the human body does not need that much. "The best daily reserve of human vitamin C is 200 to 300 mg, with a minimum of 60 mg. The general maximum tolerance of human body to vitamin C is1000 mg per day; The recommended amount for adults of China Nutrition Society is 100 mg per day. "
