NATIONAL FOOD CONSUMPTION.

estimates rather than overestimates the fact. Of the carbohydrates, 

 probably there is 20 per cent, of edible wastage. 



The total statistical consumption (ingestion plus edible wastage) 

 of human food in the United States, by years from 191 1 to 1918, 

 is shown on an " adult man " per capita basis in Table XV. 



TABLE XV. ■ 

 Summary of Consumption per Adult Man. 



Applying the estimated percentage deductions for edible wastage 

 stated above to the per capita average for the whole period we have 

 the following results for ingested human food : 



114 grams protein per man per day, 

 127 grams fat per man per day, 

 433 grams carbohydrate per man per day, 

 3424 calories per man per day. 

 These figures are probably very close to the fact as regards pro- 

 tein and carbohydrate. They are undoubtedly somewhat too high 

 still as regards fat, because the edible wastage of this component 

 is higher than the 25 per cent. used. The intention, however, has 

 been to use the most conservative figures in estimating waste. 



For purposes of comparison Table XVI. is inserted. This table 

 is based upon certain American dietary studies analyzed m the 

 writer's statistical laboratory. 



The general agreement of these results with those set forth in 

 the present study, which were reached by totally different procedure,
