Considering all the data in the table it would appear that the food 

 provided, that is, sent from the kitchen to the dinino- room, was suffi- 

 cient to supply 116 g-rams of protein and 3,403 calories of energ-y per 

 man per day. 



KITCHEN WASTE. 



The data recorded in the investigations did not include an account of 

 the total amount of food brought into each kitchen. Hence, it is not 

 possible to determine the total amount of kitchen waste. It is possi- 

 ble, however, to make a general estimate on the basis of the quantities 

 of nutrients and energy per man per day sent to the kitchen. 



As explained on page 71, statistics were obtained regarding the 

 amounts of food issued from the storeroom to all the kitchens of the 

 institution for a year, and the quantities of nutrients and energy per 

 man per day were computed on the basis of the average population 

 for the year. These results are given in Table 30 on page 72. In 

 Table 33 are summarized the results of the investigations regarding the 

 quantities of nutrients and energy per man per day in the food sent 

 from the kitchens to the dining rooms. There is therefore an oppor- 

 tunity to compare average figures for food received in the kitchens 

 from the storeroom and food sent from the kitchens to the dining 

 rooms. The diilerence shoukl represent loss incident to preparation 

 and cooking. Such a comparison is given in the following table:

Strictly speaking, such a comparison is not warranted for two reasons. 

 In the first place, as already explained, the average consumption for 

 the whole population can not be determined from the investigations 

 reported, because these do not include any studies with women patients; 

 hence, nothing certain is known regarding the consumption of the 

 women as compared with that of the men. In making the computa- 

 tions regarding food issued it was assumed that the food consumption 

 of a woman would be eight-tenths that of a man. In the second 

 place, the statistics obtained for the food issued from the storeroom 

 to the kitchens of the whole institution were not for the same period 

 as that in which the studies were made, but for the year just preced- 

 ing. However, so far as could be ascertained from a cursory exami- 

 nation of the accounts for the period of the studies, the supplies for 

 the two vears differed so little in character and amount that the esti-
