FOODS HUMAN NUTRITION. 



561 



111 tbe socond of these papers the results of dietary studies in Baltimore are 

 given. These studies were made in homes for the aged and in orphan asy- 

 lums, the institutions selected being regarded as typical of those under munici- 

 pal management, in which economy is a prerequisite, and those under private 

 management, in which there may be opportunity for more liberal expenditures. 

 Tbe objects of this investigation, as of the studies in Philadelphia, were to 

 secure data regarding the food consumption of aged persons and young chil- 

 dren for use in formulating dietary standards, to obtain additional data re- 

 garding problems of institution mangement, and to demonstrate the importance 

 from the standpoint of the institution itself of securing information of the 

 chai'acter supplied by such nutrition studies. 



The data regarding the food consumption in the institutions studied are sum- 

 marized in the table below. Bayview Asylum, one of the institutions included, 

 is the Baltimore city almshouse, and a large proportion of the inmates are aged 

 men and women. In the case of the other institution the name shows whether 

 the inmates were aged persons or children.

The results of the investigations reported in this bulletin are discussed in 

 comparison with data obtained elsewhere and with reference to dietarj^ stand- 

 ards for aged persons and for children. 



" On the basis of the work reported In this bulletin and other available data, 

 it seems fair to propose 0.9 as the factor representing the proportion of protein 

 and energy required in old age by a man or woman as compared with a man 

 at moderate muscular work during the period of full vigor, and 0.7 to 0.8 as 

 ihe factor representing the relative food requirement for extreme old age. The 

 actual quantities of protein and energy will vary according to the basis of com-
