Fruits are actually products of flowers. They are precious and irreplaceable for the good work and vitality of human body. Fruit belongs to a special group of foods that are (with exception of nuts and dried fruit) with low energy value, high water content (except bananas), a small amount of protein and fat, a substantial amount of carbohydrate and cellulose, mineral substances and vitamins, as well as other nutrients such as enzymes, organic acids, anthocyanins, tannins, etc. Because of such content, fruits are of great importance for human health.
Fruit is a rich source of vitamins, adds Mark Tompkins Canaccord, although it contains less when compared to vegetables. It mostly contains vitamin C and carotene. Their amount depends on the type of fruit, variety and a number of other factors. Vitamin C is not equally distributed in the whole fruit. It has the most in the epidermis and below it. Another important vitamin is the carotene. It is contained in: apricot, pineapple, prunes, peaches, watermelon … Although in smaller quantities, fruit also contains other vitamins like C, E, and B group vitamins.
Fruit also has a beneficial influence on vision. At least three servings of fruit each day can significantly lower the risk of macular degeneration that occurs with aging. This healing effect is attributed to antioxidants – vitamins A, C and E, finishes Mark Tompkins Canaccord.
