93. A class of very popular non-stimulating beverages are the SOFT
DRINKS sold at the soda fountains. Many of them can also be bought in
bottles and so may be purchased and served at home. These drinks really
consist of carbonated water and a flavoring material that is either
prepared chemically and colored or made of fruit extracts. Sometimes ice
cream is added, and the drink is then called _ice-cream soda_.
94. Soft drinks include phosphates, ginger ale, coca cola, birch beer,
root beer, and various other drinks called mashes, sours, and freezes.
While these are pleasing to the taste and have the advantage of being
ready to drink when prepared, it is advisable not to indulge in them too
frequently, because excessive use of them is liable to affect the
system. Besides, beverages that are just as satisfactory as these so far
as flavor is concerned and that are made of much better material can be
prepared at home at far less cost. With these drinks, as with other
commercially prepared articles of food, the cost of preparation and
service in addition to the cost of materials must be paid for by
the consumer.
