and little education. Some, however, had been under the influence of 

 Hampton Institute, and the effect of education as shown by the 

 improvement in their dietary habits was marked. 



Of particular interest in these studies is the influence of the prox- 

 imity to salt water upon the diet of the negro families. Fish formed 

 an important part of their diet, replacing to a certain extent the bacon 

 of the Alabama negro. In this way the protein in the diet was much 

 larger than in the dietary studies in Alabama, approaching more 

 nearly the average for persons under ordinary circumstances. The 

 results of this investigation are published in Bui. No. 71 of the Office 

 of Experiment Stations, on Dietary Studies of Negroes in Eastern 

 Virginia in 1897 and 1898, by H. B. Frissel and Isabel Bevier. 



SOME RESULTS OF NUTRITION INVESTIGATIONS. 



DIETARY STUDIES. 



Among the results of general interest are those of the studies of the 

 actual food consumption of people of different classes and in different 

 parts of the United States. These included dietary studies in families 

 of farmers, mechanics, and men in professional life, of people in the 

 congested districts of the slums of New York*and Chicago, of negroes 

 in the South, of Spaniards in the extreme Southwest, and of Chinese 

 on the Pacific coast. The following table shows the extent of the 

 dietary investigations: 



Statistics of dietary studies. 



The results of the more important dietary studies thus far made are 

 summarized in the table following, which shows the average amounts of 

 both the total nutrients in the food consumed, as calculated from the 

 weights and chemical composition, and the digestible nutrients as esti-
