day, but little if any clear sugar should be given (cereals should be
served with very little if any sugar).

7. Fats:

For each person over five 2-3 oz. of fat (purchased
as such) a day, depending
upon the age and ability
of the individual to digest
fats.

~Suggestions for Serving Meals.~--After reckoning the number of
calories needed for the day, it is well to remember that the protein
must be adequate in type and amount; that there should be an abundant
supply of vitamines and iron in each day's ration; that milk should
always be included in order to make sure of having a sufficient amount
of calcium in the diet; that there should be only one heavy protein
dish at any one meal, and that it is unwise to serve a meal in which
the fluids predominate on account of their deficiency in energy and
proteins.

If a meal is made up of the right kind of foods, in the proper
proportion, and each individual eats sufficient to assure the
maintenance of the normal weight, is free from gastro-intestinal
disturbances, and shows a normal resistance to disease, it is more
than probable that a sufficient quantity is being consumed each day.

All foods should be carefully selected, and properly prepared in order
to derive the maximum benefit therefrom, and the regularity and
attractiveness with which the meals are served have almost as much to
do with the health and happiness of the individual, as the character
of the foods included in the day's dietary.

PROBLEMS

(a) Calculate the dietary requirements of a nurse weighing 125 pounds,
who spends 8 hours sleeping, 8 hours on duty, 2 hours at meals, 2
hours brisk walking, 2 hours in the class room, and 2 hours reading or
studying.

(b) Calculate the diet for a child of ten years of age, weighing 65
pounds, showing the number of calories, the amount of protein,
calcium, phosphorus and iron necessary to make this diet cover the
requirements of the child.
