60 



cents per man per day, and ol)tained just as much protein as the fam- 

 ily in dietary study No. 8a for 26.4 cents, but on]}- about two-thirds 

 as much energy ; this deficiency being due to the fact that the}" expended 

 a smaller proyjortion of their money upon pork and vegetable foods and 

 thus secured less fat and carbohydrates. The family in dietary study 

 No. 7a were certainly underfed; they spent but 9.1 cents per man per 

 day for food, and obtained for it but 65 grams of protein and a little 

 over 1,700 calories of energy. Their purchases, however, were just 

 about as economical as those in dietary study No. 11a. 



The results with the two Italian families studied differed consid- 

 erably. The family in study No. 12a spent 22.7 cents per man per 

 day. and obtained 102 grams of protein, and nearl}" 3,500 calories of 

 energy, while the famih' in study No. 13a sjoent 35.1: cents and got a little 

 more protein — 127 grams — but only about two-thirds as nuich energy 

 as in No. 12a. These were among the least economical of the families 

 included in these studies. 



The group in which there was the most uniformity as regards the 

 quantity of nutrients and energy of the diet, and also with respect to 

 economy of purchase, was that made up of German families. In the 

 average of the 6 families of this group the diet cost 20.6 cents per man 

 per day, and furnished 130 grams of protein and very nearly 3,7<>0 calo- 

 ries of energy. One family in this study was considerably underfed, 

 spending oidy 10.2 cents per man per dav for their food. This was 

 practically just half of the amount spent by the average; but for this 

 expenditui'e the}' secured very nearly half of the protein and energy 

 found in the average diet for the group. 



Of all the families studied in Philadelphia, the woman in dietary 

 study No. 21a of this group was believed by the investigator to show 

 the most intelligence on the subject of marketing. She had tried all 

 the markets in the vicinity of her home until she had found the most 

 reasonable one, which she then patronized regularly. For 20.2 cents 

 per man per day she secured 150 grams of protein and 5,(»63 calories 

 of energy, while the family in study No. 22a, to obtain almost as 

 much protein, but somewhat less energy, expended 28.5 cents. 



In the average of the results with the five Jewish families the cost 

 of the diet was the same as that for the German families, but the 

 average diet of the Jewish families provided on the average only 120 

 grams of protein and 3,086 calories of energy. Two of the families, 

 those in the studies Nos. 11a and 15a. were decidedly less economical 

 than the rest of the group, and although they spent a sufficient amount 

 of money they were hardly sufiiciently fed when compared with other 

 families and with the average of all of them. 



The cost of the diet in the average for the three Irish families was 

 very nearly the same as that for the Italian families, but the quanti-
