Mineral salts, such as lime, iron, etc., are also essential to 

 the body and there are peculiar substances T f 



called vitamins present in certain foods, v . 

 such as fruits, unpolished rice, etc., which . 

 are necessary for its normal development. 

 The disease beri-beri among the Philippine scouts was due 

 to the lack of such substances in a diet made up largely of 

 polished rice, and was cured by a change in diet. As wide 

 a variety of foods as possible should be included in the diet, 

 and fads as to the avoidance of certain foodstuffs frowned 

 upon. A certain proportion of hard, bulky and indigestible 

 foods, such as crusts, fibrous vegetables and nuts, is essen- 

 tial to the proper working of the bowels. Ample protein, 

 salts and vitamins will be secured by the normal instincts 

 if unhampered by economic limitations, so that the whole 

 question comes down to one of costs. Professor Lusk esti- 

 mates that the average cost of a group of staple articles has 

 increased from 11 cents in 1916 to 18 cents in 1917 for an 

 amount that would supply 2,500 calories. To help meet 

 the problem of this increased cost of living he has prepared 

 the following low-cost meatless dietary of high caloric value, 

 designed for a family of five persons, the father at work 

 and the mother doing household work. Potatoes, with 

 their valuable alkaline salts, had to be excluded from the 

 diet because of their prohibitive price. The cost amounted 

 to SI. 16 daily for 14,400 calories, or eight cents per thousand 

 calories, which is not a high price:
