CHAPTER VIII
Food Requirement
Daily Energy Requirement. — One hears much concerning
working efficiency, i.e. the ability to do the maximum amount
of work of the highest order with a minimum waste of effort.
There is no doubt that the kind and quantity of food that
an individual consumes has much to do with his working
efficiency, and that it is consequently a matter worthy of
serious consideration. Enough coal is used in a steam
engine so that there is produced sufficient power to move a
train of cars at the desired speed. So sufficient food should
be used by the individual that enough energy is supplied to
his body for its greatest usefulness.
Since foods furnish the body with energy, the energy which
the body spends in doing its work is a measure of tlie fuel food
needed. If the body requires a certain amount of energy for
its needs, this energy, measured in Calories, can be supplied
by a definite quantity of combustible food. Hence, daily
energy requirements can be measured in Calories.
Scientists have done much experimenting and investigat-
ing concerning the quantity of food that individuals re-
quire. They have concluded that many factors may be
taken into consideration in determining daily food require-
ments or dietary standards. Some of these factors are:
(1) season; (2) -weight, size, and shape of the individual;
(3) occupation; (4) age; (5) sex.

ally less food, especially fat, is needed in summer time.
If, however, an individual works indoors in the winter time
at about the same temperature as average summer tempera-
ture, very little difference should be made in the quantity
of food. The amount of perspiration also influences the
quantity of food. An indoor worker who perspires freely
at his work requires as much food as an outdoor worker
doing the same work without profuse perspiration.
