How to Determine the Number of Calories Required Daily
by an Individual Using the Above Table
Woman. Age 35. Weight 125
Sleeping 8 hours
Slight exercise :
At meals, sewing, reading, etc. 8 hours
At light exercise :
Standing and walking 6 hours
At active muscular exercise:
General housework 2 hours
8 X .4 calorie = 3.2 calories
8 X .6 calorie = 4.8 calories
6X lecalorie =6_ ecalories
2X 2calories = 4 calories
18 calories required per pound of body weight
125 X 18 calories = 2250 calories for day’s requirement.
Other calculations show that the needs of a person esti- mated ir calories vary from twenty-two to thirty-five hun- dred for one day. Of this amount from ten to fifteen per cent (220 to 425 calories) should come from protein foods and .015 iron gram should be furnished.
It is not necessary to consider the amount of calcium (of which .7 gram is the daily requirement) if one pint of milk is supphed for each person. An adequate milk supply will furnish also one-third the amount of phosphorus required, making this calculation practically unnecessary.
Foods rich in fats have the highest caloric value, while foods rich in protein, sugar, and starch have greater caloric value than those containing much water.
The following table will enable one to calculate quickly the number of calories, protein calories, and grams of iron supplied by the more common foods. The figures for the most part are given in hundreds and even numbers to facili- tate this calculation. They therefore vary slightly from those found in Bulletin 28, Department of Agriculture, but
