Some people, the Japanese for
example, habitually eat but little. But it is the habit of both
Europeans and Americans to use considerable fat both on the table and
in cooking. The taste of food is not so pleasing without it. Their
recipes almost all use fat in one form or another, so that when little
or none is available, a change must be made in most of the methods of
cooking. Practically all food must be boiled, and is lacking in the
flavor and texture to which we are accustomed. The food, no matter how
nutritious it may be, will not taste good.
Fats are very concentrated food, a fact which gives them added value
in war-time, making them the most economical food to ship. A POUND OF
ANY FAT GIVES 21/4 TIMES AS MUCH ENERGY AS A POUND OF SUGAR--the reason
for the slogan "Fats Are Fuel for Fighters." Soldiers engaged in the
most strenuous physical activities need fuel for all the energy they
expend. Bacon, butter, all the forms of fat give them the most energy
in the smallest weight of food.
Fats stave off the feeling of hunger longer than other foods because
they pass more slowly from the stomach and delay the passage of foods
eaten with them. A slice of bread and butter will "satisfy" one for a
much longer time than a slice of bread and jelly, even though there is
enough jelly to give exactly the same amount of fuel. In the countries
in which there is a fat shortage, the appetite does not stay satisfied
during the usual period between meals, even when the previous meal
contained the customary amount of calories.
