Ill * Fruits and Their Preparation Fruits are important sources of natural sugars in the diet. Since fruit serves as a vehicle for the distribution of the seed of the plant, it is not strange to find that in this group of foods aesthetic qualities prevail. They have not only desirable sweetness, but in addition pleasing odors and flavors. They would tempt the appetite even if they had little food value, but fruits are by no means just food accessories, important as this func¬ tion may be. They also contribute impor¬ tant nutrients to the diet. Fruits are used fresh, frozen, canned, and dried. By far the largest amount is consumed fresh. There are many kinds and varieties of fruit but no attempt will be made here to classify fruits horticulturally. From the point of view of their nutritive value, fruits are placed in two groups: those which are rich sources of vitamin C, such as citrus fruits and berries; and the other fruits which are less rich in this nutrient and are grouped with "other fruits and vegetables.” Another grouping of fresh fruits useful to dietitians is on the basis of their use as food fruits or flavor fruits. The food fruits are those which contain more than 20 per cent solids and so are comparatively high in calorie content. This group includes avo¬ cados, bananas, figs, dates, certain varieties of grapes, and olives. The fruits valued prin¬ cipally for their pleasant flavor and mineral and vitamin content have less than 20 per cent solids. This group includes apples, apricots, peaches, pears, plums, cherries, cranberries, currants, berries, all the citrus fruits, pineapples, and melons. COMPOSITION AND NUTRITIVE VALUE Different kinds of fresh fruit vary con¬ siderably in composition. Even different lots of the same kind of fruit may show consider¬ able differences in composition, depending on variety, cultural condition, and degree of maturity. Table XI indicates the nutrients most important in the more common fruits. The water content of the edible portions of flavor fruits varies from 85 per cent in black¬ berries to 93 per cent in melons. Most fruits are not important sources of proteins or fat. Two exceptions are the avocado (alligator pear) and the ripe olive. The percentage of fat in both these fruits is sufficient to make them useful sources of energy. The carbohydrate in ripe fruit is present largely in the form of sugars — sucrose, dex¬ trose, and levulose. Sugars are an easily available form of energy and also make an important contribution to flavor. Fruits are among the best food sources of minerals — calcium, phosphorus, and iron — and also contain the other elements found in natural foods.
