The results of the four studies are summarized in the following table, 

 which includes for the sake of comparison the quantities of nuti'ients 

 as estimated from the proposed menus in two studies: 



Table 5. — Summary of results of dietary studies at Boston School of Housekeeping. 



The quantity of protein in the diet of the group under the usual 

 conditions of the school was practically the same as that of the com- 

 monly' accepted standard for women at light to moderate muscular 

 work, but the quantity of energy was more than 25 per cent above that 

 of the standard, owing to the fact that the amounts of fat and carbo- 

 hydrates in the diet were rather lil)era'. 



As compared with the results of dietaiy studies made elsewhere, the 

 cost in this study, 28 cents per Avoman per day, was rather high, espe- 

 cia h^ in view of the fact that much of the food was bought at whole- 

 sale rates. In the average of 18 studies of professional men's families 

 made in different parts of the country the diet, which was purchased 

 at retail, cost only 26 cents per man per day, while it supplied 108 

 grams of protein and 3,300 calories of energ3'. In seven studies made 

 in New York City the diet, which was believed to be rather expc^isive, 

 cost on an average, at retail prices, 26 cents per man per day, and fur- 

 nished 138 grams of protein and 3,747 calories of energy. In a dietar}'^ 

 stud}' with a women students' club at North Dakota Agricultural Col- 

 lege '^ the cost of the diet was only 11 cents per woman per day, yet 

 the food supplied 70 grams of protein and 2,795 calories of energy per 

 woman per day, and in a stud}' at Lake Erie Co lego« food costing 18 

 cents supplied 78 grams of protein and 2,835 calories of energy per 

 woman per day. 



When the expenditure for food was limited to a moderate sum, 

 under the experimental conditions in the studies at the School of 

 Housekeeping, the cost per woman per day was 23 cents, or just 

 5 cents less than in the study under usual conditions. The food 

 used in this study supplied almost exactly the same quantity of 

 protein, but 150 calories of energy less per woman per day than was 

 found in the regular dietary. As regards the dietary of medium cost, 

 it may be said in general that the meals were pleasing and satisfactory
