10.6 per cent protein; 1.1 per cent fat; 76.3 per cent
carbohydrates. Then, 1 ounce of flour contains, 0.106
ounce of protein; 0.011 ounce of fat; 0.763 ounce car-
bohydrates.
The protein in one ounce of flour yields (113 X 0.106 = )
11.97 Calories.
The fat in one ounce of flour yields (255 x 0.011 = ) 2.80
Calories. The carbohydrates in one ounce of flour yield
(113 x 0.763 = ) 86.21 Calories.
Total Calories furnished by 1 ounce of flour are (11.97 +
2.80 + 86.21 = ) 100.98.
Butter. — The fuel content of butter is (see United States
Department of Agriculture Bulletin 28, p. 54) :
1 per cent protein ; 85 per cent fat ; no carbohydrates.
1 ounce of butter contains 0.01 ounce of protein, 0.85
ounce of fat, and no carbohydrates.
The protein in one ounce of butter yields (0.01 x 113 = )
1.13 Calories.
The fat in one ounce of butter yields (0.85 x 255 = )
216.75 Calories.
Number of total Calories furnished by one ounce of butter
are (1.13 + 216.75 = ) 217.88.
Sugar. — The fuel content of sugar is (see United States
Department of Agriculture Bulletin No. 28, p. 65) no
per cent protein; no per cent fat; 100 per cent carbo-
hydrates.
1 ounce of sugar contains no protein, no fat, and 1 ounce
carbohydrates. 1 ounce • sugar yields (113 X 1 =) 113
Calories.
360 THE PLANNING AND SERVING OF MEALS
How the Weight of Food Materials Producing xoo Calories is
Measured. — For practical work in computing the fuel value
of foods, it has been found more convenient to reduce all
data to terms which express equal fuel value instead of equal

weight as in the foregoing paragraph. One hundred Calories
is the unit chosen. The weight of a food which, when
burned in the body, will produce one hundred Calories is the
desired datum. This weight is termed a standard portion
or a 100-Calorie portion, (See Figs. 87 and 88.)
From the previous work, it is a simple matter to compute
THE FUEL VALUE OF FOODS 361
in ounces the quantity of food materials which will yield
100 Calories.
If 1 ounce of flour yields 100.98 Calories and x represents
the number of ounces of flour which will yield 100 Calories,
then -= or x = 0.99, the number of ounces of flour

How the Fuel Value of a Combination of Food Materials is
Measured. — It is possible to compute the fuel value of a
food that is made up of several food materials. To do this
one must know or find :
(a) Recipe for food.
(6) Weight and measure of combustible food materials,
(c) Number of Calories yielded by one ounce of each of
the combustible foodstuffs.
The recipe for one loaf of bread is (see p. 231) :
1 cupful water £ tablespoonf ul butter
1 teaspoonf ul salt J cake compressed yeast
1 teaspoonf ul sugar J cupful water
3J cupfuls flour
By weighing and measuring one finds :
1 pound sugar measures 2 cupfuls
1 pound butter measures 2 cupfuls
1 pound flour measures 4 cupfuls ✪ Homemade Bread
