We have a very large number of complete investigations upon the
diet of people of different vocations in America, but they are too exten-
sive to enter into, hence we must refer to the original publications of
Atwater.6
It is evident that persons of essentially different weight of body
who live under unequal external conditions must need essentially dif-
ferent food. It is also to be expected (and this is confirmed by the table)
that not only the absolute quantity of food consumed by various persons,
but also the relative proportion of the various organic nutritive substances,
shows considerable variation. Results for the daily need of human
beings in general cannot be given. For certain classes, such as soldiers,
laborers, etc., results may be given which are valuable for the calculation
of the daily rations.
Based on extensive investigations and a very wide experience, Voit
has proposed the following average quantities for the daily diet of adults:
Proteins. Fat. Carbohydrates. Calories.
For men 118 grams 56 grams 500 grams 2810
But it should be remarked that these data relate to a man weighing
70 to 75 kilos and who was engaged daily for ten hours in not too fatiguing
labor.
The quantity of food required by a woman engaged in moderate work

In regard to the earlier researches cited in this table, we refer the reader to Voit,
in Hermann’s Handbuch, 6, 519.
