Fruit and juice assortment. View of a wide variety of fruits and bottles of home-made fruit juice. The fruits seen here include apples, a pear, strawberries, blackberries, grapes, an apricot, a nectarine, a peach and raspberries. Fresh fruits are a very important dietary source of vitamins (especially A and C) and minerals, including potassium, magnesium and calcium. Juices are a good way of mixing the flavours of many fruits, and can usually be kept longer than the fresh fruits themselves.
