DIETARY STUDIES. 



137 



The tables show very conclusively that the intention to 

 materially modify the kind of animal foods in passing from diet- 

 ary No. 149 to dietary No. 150 was carried out. The use of 

 beef, veal, mutton, poultry, and eggs was greatly diminished and 

 the consumption of pork and milk increased. The butter eaten 

 was less in the latter period also. In dietaries Nos. 151 and 152 

 the character of the animal foods other than the milk did not 

 differ greatly. The quantities of high-cost meats were less, but 

 their place was not taken by low-cost meats. 



The above figures leave no room for doubt that the free use of 

 milk diminishes the consumption of other foods. In passing 

 from dietary No. 149 to No. 150 the milk consumption per man 

 increased from 810 grams daily to 1,197, and the use of other 

 animal foods decreased from 801 grams to 498 grams, while the 

 vegetable foods were eaten in about the same quantities in the 

 two studies. 



Essentially the same result follows in dietaries Nos. 151 and 

 152, where the milk eaten increased from 873 grams daily to 

 1,223, the consumption of other animal foods decreasing from 

 541 grams to 481, and of vegetable foods from 1,490 to 1,126 

 grams. In the first instance the milk replaced other animal 

 foods, and in the second there was mainly a decrease in the use 

 of vegetable foods. But while the increased consumption of 

 milk diminished the consumption of other materials, what was 

 the effect upon the actual quantity of nutrients taken and upon 

 the cost of the dietary? 



The answer to the question is very definite, and may be found 

 in the following comparison of the results of the investigations:
