938 METABOLISM.
the following tables give the rations of soldiers in peace and in the field
and the average figures from the detailed data of various countries: 1
A. Peace Ration. B. War Ration.
Proteins. Fat. Carbohydrates. Proteins. Fat. Carbohydrates.

Maximum... 165 97 (il 197 95 688

The following figures for the daily ration are obtained from the above
averages:
Proteins. Fat. Carbohydrates. Calories.

If we calculate the fat in its equivalent quantity of starch, then the
relation of the proteins to the non-nitrogenous foods is:

The relation in both cases is nearly the same. Similar results. are
obtained when we start with VortT’s figures for a soldier in manceuver A
(hard work) and B (strenuous work) in war.
Proteins. Fat. Carbohydrates. Calories.

The relation here, when the fat is recalculated as starch, in both cases is
the same, or equal to 1: 5.
If we calculate that portion of the total calories supplied which falls
to each group of the foodstuffs, it is found that 16-19 per cent comes
from the protein in rest as well as with medium and strenuous work.
For the fat and the carbohydrates the variations are greater; the chief
quantity of calories comes from the carbohydrates. Of the total calories
16-30 per cent comes from the fat and 50-60 per cent from the carbo-
hydrates. |
The importance of the food-demand for working individuals is shown
by the figures given on page 933 for a wood-chopper in Bavaria. A
need of more than 4000 calories occurs but seldom, and with very hard
work the demand may rise even to 7000 calories (ATWATER and BRYANT,
JAFFA 7).
1Germany, Austria, Switzerland, France, Italy, Russia, and the United States.
It is not known by the author whether these figures have been changed in the last
few years in the various countries, and hence whether they must be modified or not.
