NUTRITION INVESTIGATIONS. ^3 



instruction regarding the nutritive value of different foods and ways 

 of handling and cooking them is an important feature. These col- 

 leges have for years looked to the Department for aid in this line 

 and are now doing so more than ever. The agricultural colleges have 

 l)een stimulated by a recent act of Congress to organize courses for 

 teachers along this line, as well as other branches of agricultural and 

 mechanical arts. Secondary and primary schools all over the coun- 

 try are taking up this work, and the demand for teachers and for 

 information outruns the supply. 



Recognizing the importance of the nutrition investigations of the 

 Department in this connection, students, teachers, investigators, and 

 indivichials interested in the problems are turning to the Depart- 

 ment in increasing numbers for information and suggestions. This 

 is one phase of the great movement for the improvement of life in 

 both country and city through education directly relating to home 

 interests and the vocations of the people and the dissemination of 

 information along such lines. It has long been understood that work 

 of this character has been undertaken by the Department, and the 

 demand for information continues to increase. 



In accordance with the usual policy of the Department, the results 

 of the nutrition investigations have been published as technical bul- 

 letins in limited editions, while the general deductions of popular 

 interest whicli have been drawn from the investigations have been 

 summarized in Farmers' Bulletins and other popular publications 

 designed for general circulation. 



Up to the present time 59 technical bulletins and 43 Farmers' Bul- 

 letins and other popular summaries have been published as a result 

 .of the nutrition investigations, as well as numerous reports of prog- 

 ress and similar articles. The nutrition publications issued during 

 the past year have included three technical bulletins, one Farmers' 

 Bulletin, and one circular. The subjects treated in these publica- 

 tions are as follows: The influence of muscular and mental work on 

 metal)olism and the efficiencv of the human bodv as a machine; diet- 

 ary studies in rural regions in Vermont, Tennessee, and Georgia ; and 

 dietary studies in public institutions in Philadeli)hia and Baltimore; 

 all three of these publications being technical bulletins. The Farm- 

 ers' Bulletins have to do with the use of milk as food and the care of 

 food in the home. The circular brieHv describes the organ.ization of 

 the nutrition investigations and lists and describes the publications 

 issued in connection with the enterprise. 



In addition to the above, a new Farmers' Bulletin has been prepared 

 for publication, and one of the earlier issues has be-en rewritten and 

 brought uj) to date, while three special articles have also been ])re- 

 l)ared for publication and two technical bulletins are approaching 

 completion.
