EXPERIMENT STATION RECORD. 



"The negro dietaries show on the average a liberal allowance of fuel ingredients 

 in the food as measured by the fuel values. Rut the quantities of protein are 

 extremely small, in general from one-half to two-thirds the amounts which the 

 standards call for and which are actually found in the food of well-to-do and well- 

 nourished people of different classes in the United States and in Europe. The nutri- 

 tive ratios of the negro dietaries are very wide as compared with those of both the 

 dietary standards and the actual dietaries of people who are ordinarily assumed to 

 be well nourished." 



Dietary studies at the Maine State College in 1895, W. H. 



Jordan (U. 8. Dept. Agr., Office of Experiment Stations Bui. 37, pp. 

 57). — Dietary studies were conducted at the college boarding house in 

 which the attempt was made to control to some extent the source and 

 supply of animal foods. The object of this was to compare high and 

 low cost foods as the source of protein "with special attention to the 

 influence of the free use of milk as a low-cost animal food upon the 

 character and cost of the dietary." The author points out that milk is 

 a very nutritious and inexpensive article of diet, yet the fact is not 

 generally recognized that its liberal use in the dietary is economical. 

 The opinion is prevalent that the abundant use of milk does not 

 diminish the quantity of other foods consumed. 



Five dietary studies were made. The first was under ordinary con- 

 ditions. In the second the protein was derived from expensive sources, 

 i. e., high-priced meats, fish, and poultry; in the third protein was 

 derived from cheap sources, i. e., low-priced meats, milk, and beans; 

 in the fourth and fifth no departure was made from the ordinary con- 

 ditions, except in the amount of milk supplied, in the fourth the milk 

 supply being limited and in the fifth very abundant. The methods 

 followed in making the investigation were practically those described 

 in Bulletin 21 of this Office (E. S. R., 7, p. 148). A number of foods 

 were analyzed in connection with the dietary studies. The composi- 

 tion of the others was computed from standard tables. 



Tables are given which show the kind and amount of food purchased, 

 wasted, and eaten and its cost, composition, and fuel value. The 

 results are briefly summed up as follows : 



Results of dietary studies — food eaten per man per day. 



First dietary : Usual food supply 



Second dietary: (Justly meats: milk limited 



Third dietary : Milk iu abundance; oilier protein less costly 



Fourth dietary: Milk supply limited ". 



Fifth dietary : Milk supply unlimited

The average daily cost per man of the food purchased for the 5 dietary 

 studies was 26 cts., 34 cts., 26 cts., 27 cts., and 25 cts., respectively. The 

 results are discussed in detail.
