THE FOOD VALUES OF MILK 



Milk is consumed by adults in very moderate or small quan- 

 tities, and that along with much other material, and is therefore 

 most valuable when it contains the most food units.. For instance, 

 average Jersey and Guernsey milk is rich, not only in fat, but in 

 other solid food substances and to adults is worth about 40 per 

 cent more per quart than the average city milk dispensed

throughout America. The infant, however, derives all his 

 food from milk and therefore that milk is, most valuable to the 

 infant which will produce the strongest body and this is not the 

 rich milk but rather that of about 2!/o to 3^ per cent fat and 

 comparatively rich in minerals and protein and vitamine, i. e., 

 Holstein or Ayrshire milk. 



COST OF DAIRY FOODS 



Contrary to general notion, food in the form of milk is not 

 particularly expensive when compared to* any of the meats, fish 

 or fowl, green vegetablesi or fruits. This is illustrated in the 

 following table, worked out to show the cost per pound of the 

 solid food ingredients in various common food stuffs, after the 

 natural waste and water of these have been figured out. 



A better view of this matter, however, can be obtained by a 

 study of the graph (Fig. 132, page 410).
