Possibly there were some to whom the food was decidedly unattractive, 

 so that their appetites were not stimulated. But it is difficult to believe 

 that any large proportion failed to obtain sufficient nourishment, and 

 the opinion that the subjects of these studies were not undernourished 

 seemed to be justified b}^ their appearance and general condition. 



On the other hand, it covdd not be affirmed that the patients in study 

 No. 379, whose average food consumption was so much larger than 

 that in either of the other studies, were overfed. No explanation of 

 the wide diflferences in the results of these three studies can be given 

 other than that the inclinations of the patients seemed to vary. While 

 it was the opinion of those in charge that the food consumption in 

 each case during the time of these studies was about the same as usual, 

 it is not certain that similar studies with the same patients at another 

 time would not have given results showing more uniformity between 

 the individual studies, as was the case in the preceding group. 



The results in these three studies (Nos, 368, 376, and 379) are so vary- 

 ing that the average can hardly be taken as representative; yet it is 

 interesting to note that such an average is close to the standard men- 

 tioned above for a man in health with very little muscular activity. 

 Among the studies in the New York hospitals the average consumption 

 in two with patients classed as "light workers and disturbed" was 73 

 grams of protein and 2,255 calories of energy per man per day, and the 

 average in two studies with patients classed as ' ' restless, active, and 

 disturbed" was 95 grams of protein and 2,746 calories. 



Study No. 374 was made with a group of negro patients, a large 

 proportion of whom were workers, some doing considerable amounts of 

 outdoor work. Considering the group as a whole, as has been done 

 in all the other studies, the average consumption was 98 grams of pro- 

 tein and 2,536 calories of energy per man per day. It has seemed 

 best in this case, however, to consider the consumption of the workers 

 and the nonworkers separately, since there were so many of the former 

 in the group. The results of calculations according to such a division 

 of patients, and taking account of the extra ration for the workers, 

 gives an average consumption of 108 grams of protein and 2,694 calo 

 ries of energy for the workers and 90 grams of protein and 2,402 

 calories of energy per man per day for the nonworkers. The results 

 for the nonworkers correspond quite closely to the dietary standard 

 given above for a man with "" little exercise." The results for the 

 workers are a trifle lower in protein and noticeably lower in energy 

 than the standard given for men with "light to moderate muscular 

 work." The amount of work done by these patients would probably 

 be on the average no less than that which would be represented by the 

 standard. The results of 10 studies of patients classed as "workers" 

 in the New York hospitals gave an average consumption of 105 grams 

 of protein and 2,908 calories of energy per man per day, which, like
