Th(» avonig-e food consumption in this dietary study, 131 orams 

 of protein and 4,598 calorics of energy per man per day, is much larger 

 than that of the persons with similar occupation included in the pre- 

 ceding study; in fact it is slightly higher in protein and decidedly 

 higher in energy than the commonh^ accepted American standard for 

 a man at moderately active muscular work, i. e., 125 grams of protein 

 and 3,4(10 calories of energy. Apparently these persons had large 

 appetites, or they ate more than they actually needed. They certainly 

 ate much more than ordinary people doing equivalent work. 



The excess of energy in the diet is largely due to the unusual amount 

 of sugar eaten. In no other stud}- made in this institution, with the 

 exception of No. 365 with a group of persons similar to those in the 

 present .study, was so much sugar consumed. In No. 369, the preceding 

 study with a similar group, the consumption of sugar was no more 

 than is commonl}" found. 



The food rejected in this study contained 26 per cent of the protein 

 and 20 per cent of the energy in the total food served. While this was 

 larorer than seemed necessarv, it was verv much smaller than in the pre- 

 ceding study. The ditference in the amounts rejected is accounted for 

 hy the diti'erence in amounts eaten, for the total amount of food served 

 per man per day was 3 per cent larger in study No. 370 than in No. 

 369. From a comparison of the amounts wasted in the two studies it 

 is apparent that the food provided in study No. 369 could have been 

 reduced at least 25 per cent and still leave an excess over the amount 

 actually eateu.
