1. FRUIT, as is generally understood, is the fleshy, juicy product of
some plant or tree which, when ripe, is suitable for use as food.
Although some fruits are seedless, they generally contain the seeds of
the plants or trees that produce them. Many fruits require cooking to
make them palatable, others are never cooked, and still others may be
cooked or eaten raw, as desired.
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 flavor in order that
birds might be allured to attack them for food and, by spreading the
seeds, assist in their propagation.
2. Fruits are gradually growing to be less seasonal and more a daily
food, and are thus constantly becoming more prevalent in the diet. This
condition may be attributed to the present rapid means of transportation
and the excellent methods of cold storage that exist. Through these
agencies it is possible to ship more or less perishable fruits long
distances from their native localities and at times of the year other
than the particular season in which they are at their best in the places
where they are grown. Thus, fruits that were formerly considered a
luxury may now be served regularly, even on the tables of persons having
only moderate means.
The fact that fruits are being more extensively used every day is as it
should be, for this food is entitled to an important place in the diet
of all persons. So important is fruit in the diet that it must be looked
on not as one of the things that may be taken or omitted as a person
wishes without making any difference either way, but as a food to
include in one form or another in nearly every meal. The child who is so
young that it cannot take any solid food may have fruit juices included
in its diet to decided advantage; but children who are slightly older
and adults may take the fruits cooked or raw instead of in the form
of juices.
3. As far as the composition of fruits is concerned, it is such that
most fresh fruits are not particularly high in food value. However, they
are characterized by other qualities that make up for what they lack in
this respect; then, too, what they contain in the way of heat-producing
or tissue-building material is easily digestible. Most fruits contain
considerable acid, and this food substance makes them stimulating to the
appetite. Advantage of this fact is taken when fruits are served at the
beginning of a breakfast or when several of them are combined in a fruit
cocktail and served before luncheon or dinner. This acid produces real
stimulation in the stomach, resulting in a flow of gastric juice from
the glands of the stomach walls. In addition, the delightful color, the
fragrant odor, or the pleasant taste of fruit, although a mental effect,
is just as real and just as valuable as the actual stimulation of
the acids.
4. Many fruits are eaten raw, while others are cooked either because
they require cooking to make them appetizing or because it is desired
not to use them in their raw state. The cooking of fruits has a variety
of effects on them, being sometimes advantageous and other times
detrimental. The flavor is always changed by the application of heat,
and in some cases the acid that fruit contains becomes stronger. On the
other hand, the fibrous material, or cellulose, of fruits is softened by
cooking and thus becomes more digestible. Then, too, the sugar that is
usually added to fruits in their cooking increases their food value.
Because of these facts, cooked fruits have considerable value and, like
raw fruits, should have an important place in the diet. Those fruits
which are dried and usually eaten raw, such as figs and dates, supply
much nourishment in an easily digestible form.
5. The medicinal value of fruit has long been considered to be of
importance, but this may be almost entirely disregarded, for, with the
exception of the fact that most fruits are valuable as a laxative, there
is nothing to consider. However, several fruits, such as blackberries
and bananas, have an anti-laxative effect, and large quantities of
these should for the most part be avoided, especially in the feeding
of children.
6. In general, fruits are divided into two classes, namely, food fruits
and flavor fruits. As their names imply, _food fruits_ are valuable as
food, whereas _flavor fruits_ are those distinguished by a
characteristic flavor. It should be remembered that the flavors, as well
as the odors, of fruits, are due chiefly to what is known as their
volatile, or ethereal, oils. Fruits in which these oils are very strong
are often irritating to certain persons and cause distress of some sort
after eating.
7. In this Section, it is the purpose to acquaint the housewife with the
relative value and uses of the various kinds of fruit, to teach her the
best methods of preparation, and to supply her with recipes that will
encourage her to make greater use of this valuable food in her family's
diet. In this discussion, however, the general classification of fruits
is not followed. Instead, the various fruits are arranged alphabetically
under the headings Berries, Non-Tropical Fruits, Citrus Fruits, Tropical
Fruits, Melons, and Dried Fruits, in order to simplify matters. While it
is hardly possible to use fruits too extensively, they must not be
allowed to take the place of other more nourishing foods that are
required by the body. Therefore, in order to make proper use of them,
their value in the diet should not be overlooked.
