Fruits, because they are wholesome, appetizing, and attractive, occupy a valuable place in the diet. In fact, it is these qualities rather than their food value that accounts for the popularity of fruits among all people. In addition to causing fruits to appeal to the esthetic sense, their attractiveness serves another important purpose. It is said that Nature made them attractive in color, odor, and ?avor in order that birds might be allured to attack them for food and, by spreading the seeds, assist in their propagation.
