DIETARY STANDARDS. , 
In order that the food may be adapted to the needs of the 
consumer it should have the protein and fuel ingredients (fats 
and carbohydrates) in the proper proportions. It has been as- 
sumed from the most accurate data available that an average 
laboring man, z. é., a man doing an ordinary amount of man- 
ual labor, requires in his daily food about .28 of a pound of 
protein and in addition enough fats and carbohydrates to make 
the fuel value 3,500 calories. Men in professional life with 
less muscular work generally need less food. Standards for 
men of this class call for .22 to .25 of a pound of protein and 
from 2,700 to 3,000 calories of energy. A man at severe work 
on the other hand would need large amounts of nutrients, 
.33 lb. of protein and 4,500 calories of energy for instance. 
Various combinations of foods for daily dietaries according to 
either of the standards above quoted may be made by calcula- 
tions based on the chemical composition of various foods. A 
few such calculations are here given in the form of daily menus 
in which the actual amounts of different food materials required 
by a family equivalent to four men at ordinary exercise are given. 
Such a family might, for example, consist of a man and his 
wife with three children under 10 years of age and one female 
servant, or of a man and his wife with two children between 
10 and 16 years of age and one servant. ‘The equivalent of 
any family in terms of one adult man at moderate work, one 
day, can be easily calculated by the use of the following fac- 
tors which are based in part upon experimental data and in 
part upon arbitrary assumption. While these factors do not 
represent the proportional amount consumed by every child of 
a given age they are probably on the whole as nearly accurate 
as can be obtained without considerable more experimental 
data. ‘The gradations here used are as follows:
