Table 14. — Summari/ of results of diehinj studies of Philadelphia frunilles — Cont'd. 



In several of the studies the cost of the diet per man per da\' was 

 relatively very high, and in nearly all of them it was higher than was 

 necessarj^ The average given in the table above, while indicating 

 what these families spent for their food, represents a greater amount 

 than it was neces.sary to spend in those regions, in the time when these 

 .studies were made, to provide a diet in every way as satisfactory as 

 the average obtained in the studies. Thus, 14 of the 22 families 

 included in these studies paid from 20 to 36 cents per man per da}^ for 

 food materials (not including food accessories) which supplied no more 

 nutrients or energy than it was estimated could have been obtained 

 for 15 cents if there had been more intelligence in marketing; and 

 those families who spent less than 20 cents per man per day for food 

 obtained less than they should for the money spent. This is quite 

 apparent upon a stud}' of the results summarized above. For instance, 

 among the 5 colored families 3 of them spent practicall}^ the same amount 

 for their food, namely 26.3 cents per man per day in two cases and 26. -1 

 cents in the third. But the quantities of nutrients and energy obtained 

 varied widely. Thus, in study No. 8a the famil}' obtained per man per 

 day but 80 grams of protein and 2,786 calories of energy; the family in 

 stud}^ No. 9a spent 0.1 cent per day less, but got 13 grams of protein 

 and 1,151 calories of energy more, while the family in stud}' No. 11a 

 for the same expenditure secured 187 grams of protein and over 

 4,700 calories of energy. The family in study No. 10a spent 17.2
