diet tend to suffer from tuberculosis because their vitality is lowered 

 by long continued use of a faulty diet and this pre-disposes them to 

 tuberculosis. 



"There is a large group of people throughout the south who grow a 

 cash crop such as cotton rather than engaging in diversified agriculture 

 who use the same type of diet and thereby have their resistance lowered 

 so that they become infected with pellagra, which has increased to an 

 alai'iiiing extent in recent years. 



"Dr. K. Goldberg, of the Public Health Service in Washington, has 

 made a very careful and extensive study of the diet of pellagra. He 

 finds that those who use a liberal amount of milk and some eggs do not 

 sufter from pellagra. 



"The greatest factor in the cure of tuberculosis, once it is contracted 

 is through proper hygienic treatment together with liberal feeding on 

 a diet in which milk and eggs find a very conspicuous place. 



"There has been a great reduction in the use of dairy products in the 

 United States during the last year, and this is a serious matter from 

 the standpoint of public health. The use of milk has made us what we 

 are. The keeping of dairy animals is the greatest single discovery in the 

 history of human progress. The cost of production has so increased that 

 the price must go up that the business may be profitable. 



"Every public spirited person should at this time make it his business 

 to erlucate his acquaintances in the maf;ter of using more of all kinds of 

 dairy products in order to encourage an industry which is in great 

 jeopardy." 



From the foregoing facts it is evident that the superiority of 

 milk ind the other dairy products and the important position 

 which they command as foods is due to their ability to supply pro- 

 teins which can be readily and completely used and to supply 

 sufficient vitamines to the diet to promote growth. Very few 

 other foods can do this and all of the other foods which can ac- 

 complish the same result cost from two to three times as much as 

 milk. Eggs, for instance, must sell for a price per dozen equal 

 to the price of a pint of milk before they can do the same work 

 at the same cost. Leafy vegetables are important as a component 

 of the diet for their valuable mineral content but they cannot 

 furnish enough fat soluble vitamines. 



Dairy products such as milk, cheese and cottage cheese alone are 

 our cheapest sources of an adequate supply of this essential and 

 the cheapest source of desirable proteins. 



Jn a book recently published, ' ' Every Day Foods in War Time, ' ' 

 by Mary Swartz Rose, this is found : 



"When the milk pitcher is allowed to work its magic for the human 

 race, we shall have citizens of better physique than the records of our 

 rcruitiug stations show today. Even wh'jn the family table is deprived 

 of it'? familiar wheat bread and meat, we may be ptrpng if we invoke the 

 aid of t;his friendly magician." ^
