The reason why kiwi is called the "King of Fruits" mainly refers to its very rich vitamin C content. In 100 grams of fresh fruit, the vitamin C content is 100 to 200 mg, and the highest can reach 495 mg. It is 20 to 80 times higher than apples and 30 to 140 times higher than pears. Under normal circumstances, 1 to 2 fresh kiwi fruits can meet the needs of the human body.
