The average amount of muscular work performed by the persons in 

 this group might perhaps be considered equivalent to that of a man 

 engaged at light to moderate muscular work. The counnonly accepted 

 dietary standard for this calls for 112 grams of protein and 3,050 calo- 

 ries of energy per day. The results of this study were a little lower 

 than this standard as regards protein, and slightly above as regards 

 energy. Apparently, therefore, the food consumption of these per- 

 sons was sufficient for their bodily needs. Another indication that 

 such was the case is found in the fact that the food provided was greatly 

 in excess of what' was eaten, which would naturally indicate an over- 

 supply rather than the opposite, when as was the case the diet was 

 reasonably varied and the foods were well cooked. 



The amount of food rejected in this study was very large, and con- 

 tained about 42 per cent of the protein and 37 per cent of the energy 

 of the total food served. In addition to this a considerable propor- 

 tion of some of the articles brought to the dining room was returned 

 to the kitchen. That the food provided was excessive is more plainlv 

 shown by the fact that had all the food served been eaten there would 

 have been a consumption of 172 grams of protein, 208 grams of fat, 

 and 615 grams of carbohydrates per man per da}'. 



DIETARY STUDY NO. 370— ATTENDANTS, HOUSE GIRLS, ETC. 



The group included in this stud}' comprised 22 males and 6 females 

 (house girls, attendants, waiters, etc.). As previously noted, the study 

 was carried on at the same time and under the same conditions as No. 

 369. An accurate account of the number of meals eaten was kept as 

 usual, but, unfortunately, such data for the tirst 3 days of the study 

 were lost. However, it is believed that the number did not vary 

 greatly from day to day, and that no considerable error is introduced 

 by assuming that the average attendance at each meal of the seven days 

 was the same as during the last four days. Making this assumption 

 and counting the food eaten by 1 woman as equal to 0.8 that of 1 man, 

 the total number of meals taken was equivalent to 563 for a man, or 1 

 man for 188 days. 



The menu served was the same as in dietary No. 369. 



The food statistics in detail are found in Table 35 of the Appendix. 

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

 eaten and that rejected are summarized in the following table:
