ILLINOIS. 



Nutrition investigations have been carried on in cooperation with the 

 Hull House and the Lewis Institute of Chicago and the University of 

 Illinois. The lines of work undertaken have been dietaiy studies, 

 investigations of food and -milk supply of Chicago, losses in cooking 

 meat, digestion experiments in which meat formed a considerable part 

 of the diet, and analyses of food materials. 



The work in Chicago was under the immediate direction of Miss 

 Jane Addams, of Hull House, and Prof. G. N. Carman, director of 

 Lewis Institute. The work at the University of Illinois was carried 

 on by Prof. H. S. Grindley. 



DIETARY STUDIES. 



The dietary studies were carried on mainly for the purpose of study 

 ing the food consumption of persons of foreign birth or parentage 

 residing in congested districts of Chicago. Fifty such studies were 

 made among families of Italians, French Canadians, Russian Jews, and 

 Bohemians. The details of these studies were carried on by Miss 

 Caroline Hunt, although valuable aid was received at the outset from 

 Mr. H. M. Smith, of Middletown, Conn. The results seem to indicate 

 that the diet of foreigners in this country approaches more and more 

 nearly that of the average American diet the longer they have resided 

 in this country. In addition to these three dietary studies were made 

 of well-to-do professional men residing in Chicago and two were car 

 ried on by Professor Grindley, in connection with his work at the 

 University of Illinois. In these he was assisted by Mr. J. L. Sammis 

 and Mr. E. A. Paul.
