We have a very large number of complete investigations upon the 

 diet of people of different vocations in America, but they are too exten-

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 x>f 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:
