Recently, the World Health Organization published a list of the best fruits in the world. This is the result of a study which has been implemented for nearly three years. And the following passage will introduce these fruits in detail.
Firstly, papaya
Papaya not only contains a large number of sugars, but also contains vitamins A, B vitamins, vitamin C and iron, calcium, organic acids, fiber and other nutrients. It is especially rich in β-carotene and vitamin C, and the content of vitamin C is 20 times as that of apple. β-carotene and vitamin C are natural anti-oxidants, which can effectively prevent a cold, and prevent the synthesis of carcinogenic nitrosamines. But you should pay attention: papaya should not be cooked, otherwise, the β-carotene, B vitamins and vitamin C contained in papaya will be completely destroyed, and can not achieve any health effect.
Secondly, strawberry
Strawberry contains a variety of effective ingredients. Every 100 grams of strawberry contains 60 mg of vitamin C, which is more than that in apple and grape. In addition, it also contains large amounts of carbohydrates, proteins, organic acids, pectin, vitamins B1, vitamin B2, calcium, phosphorus, iron, potassium, zinc, chromium and other essential minerals and some trace elements. Strawberry is an important source of fiber, iron, potassium, vitamin C and flavonoids, all of which are essential nutrients to human body.
Thirdly, kiwi fruit
Kiwi fruit is extremely rich in vitamin C. Every 100 grams of kiwi fruit contains 100 to 420 mg of vitamin C, which is much more than that of orange, apple and other fruits. At the same time, it also contains a lot of sugar, protein, amino acids and other organic compounds and a variety of minerals which are necessary to human body. According to the American Food Research Center, the nutrition of kiwi fruit is the most abundant and comprehensive in all the fruits.
Fourthly, orange
Orange is rich in vitamin C and citric acid. Vitamin C has some effect on skin-beauty, while citric acid plays an important role in the elimination of fatigue. What’s more, orange contains a special ingredient–hesperidin, which can strengthen the resilience of capillaries, bring down blood pressure, and expand the coronary artery of heart. As a result, it can be said that orange is the best fruit for the prevention of coronary heart disease and atherosclerosis. Researchers from the University of Florida have confirmed that, eating orange can reduce the deposition of cholesterol in the arteries, so as to help prevent and treat atherosclerosis.
