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 8.1 OZ. BREAD (WHITE. HOME MADE) 1.8 OZ. BUTTER 0.5 OZ. CHEE8E 0.8 OZ. EQ08 2.4 02. FLOUR (WHEAT AVERAGE) 1.0 OZ. MILK 6.1 OZ. POTATOES (WHITE) 4.2 OZ. BUOAR 0.9 OZ. Fig. 87. — Comparative weights of 100-Calorie portions of foods. 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 1 100.98 which yield 100 Calories, i.e. a 100-Calorie portion of flour. Fig. 88.— 100-Calorie portions of foods. If 1 ounce of butter yields 217.88 Calories and x represents the number of ounces of butter which will yield 100 Calories, then ? = or x = 0.46, the number of ounces of butter 1 217.88 ' which yield 100 Calories, i.e. a 100-Calorie portion of butter. If 1 ounce of sugar yields 113 Calories and x represents the number of ounces of sugar which will yield 100 Calories, then ^ = — - or x = 0.88, the number of ounces of sugar 362 THE PLANNING AND SERVING OF MEALS which will yield 100 Calories, i.e. a 100-Calorie portion of sugar. 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
