December B,9J0, 1952 Washington, D.C UNITED STATES DEPARTMENT OF AGRICULTURE Agriculture Handbook No.56 Foreword The National Food and Nutrition Institute was held in the Jefferson Auditorium of the U. S. Department of Agriculture, Washington, D. C, December 8 to 10, 1952, for the purpose of reviewing nutrition progress and determining ways of strength- ening existing nutrition programs. More than ^00 representatives of governmental and nongovernmental agencies carrying responsi- bilities for various phases of current food and nutrition pro- grams attended. Joint sponsors of the Institute were the U. S. Department of Agriculture, the National Institutes of Health of the U. S. Public Health Service, the Food and Nutrition Board of the National Research Council, and the Interagency Committee on Nutrition Edu- cation and School Lunch. This Interagency Committee is made up of representatives of the following Federal agencies: Children's Bureau, Office of Education, and Bureau of State Services of the Public Health Service, Federal Security Agency (now Department of Health, Education, and Welfare); Fish and Wildlife Service and Bureau of Indian Affairs of the Department of the Interior; Bureau of Human Nutrition and Home Economics, Extension Service, Farmers Home Adjninistration, Office of Foreign Agricultural Relations (now Foreign Agricultural Service), Production and Marketing Administra- tion, Rural Electrification Administration, and Office of Experi- ment Stations, Department of Agriculture; the American National Red Cross; the Federal Civil Defense Administration; and the North American Office of the Food and Agricultural Organization of the United Nations. This broad base of sponsorship resulted in a conference that gave perspective to a wide range of problems, each related to one of common interest—nutritional betterment of our people. The proceedings of the Institute were prepared under the leader- ship of the staff of the Bureau of Human Nutrition and Home Economics in consultation with staff of other sponsoring agencies.

S. Department of Agriculture, the U. S, Public Health Service, the Food and Nutrition Board of the National Research Council, and the Interagency Committee on Nutrition Education and School Lunch, provided first for helping participants acquire a common back- ground about the country^s food and nutrition situation—stock-taking, so to speak. Secondly, it provided for discussion of mutual problems and of ways to strengthen existing programs. The general sessions included an appraisal of our present knowledge of nutrition in relation to health, a review of current and prospective food supplies, information on how the national food supply tends to be divided among families and among individuals, and some estimate of the adequacy of diets and the state of the nutritional health of different population groups. They also included presentations of some pressing food problems, such as food protection and planning for emergencies. Attending the Institute and actively joining in the discussions of the situation and of what to do to improve programs were some ¿i-OO leaders of a variety of food and nutrition programs, both public and private: Nutritionists, home economists, leaders in education or research...from schools or universities...from public health or Extension services...from Red Cross organizations•..from trade associations...from Federal and National agencies. Representatives of State and city nutrition committees...of the National Research Council's Food and Nutrition Board... of professional societies such as the American Institute of Nutrition, the American Dietetic Association, the American Home Economics Association, the American Public Health Asso- ciation, and the American Medical Association. The proceedings which follow include the addresses given at the general sessions, in whole or in abstract, insofar as they were made available by the participants. They also include summaries of group discussions for each topic, based on reports from each discussion section« In briefing the discussion notes, effort was made to omit factual state- ments repeated from lectures and emphasize the important points brought out. Welcome by the Secretary of Agriculture The Secretary of Agriculture, the Honorable Charles F. Brannan, welcomed the members of the Institute to Washington and to the Depart- ment* s Jefferson Auditorium. He noted that the conference was bringing together representatives from many different groups—research, education, agriculture, medicine, industry, and trade—which was important, he said, because the complexity of problems in.nutrition require for their solu- tion the sustained collaboration by all who have concern for them. This meeting on nutrition, he believed, had great potentialities for the future. Speaking for Agriculture, he pointed out the important responsibili- ties farmers have in producing the amounts of the many kinds of food needed for a well-fed people. Nutrition begins with food, he said, and the pro- duction and marketing of food is a major part of the business of agriculture. He referred to some of the improvements that have taken place over the years in the quality of our national diet, remarking that he took pride in this dietary improvement because it rests in part on the performance of ag- riculture. It is a tribute to the increasing efficiency of production, pro- cessing, and marketing, and to research that has pointed the way. The challenge will be even greater in the years ahead as our population in- creases faster than our tillable acres. He noted that in 1975 the country will have five plates to fill for every four filled at present. And as research shows ever more clearly the part that nutrition can play in pro- viding abundant health, he said, agriculture will adjust its programs ac- cordingly. He recalled the Nutrition Conference for Defense which the President of the United States had called in 19^1, and the fact that its influence on nutrition programs is still being felt. He was sure, he said, that the deliberations of this Institute would likewise be fruitful, and expressed the hope that each participant would find the conference a stimulus to strengthen his part in the Nation's nu- trition programs. He felt the conference would lead to increased coopera- tive effort among agencies and looked forward to accelerated progress in nutrition in the years ahead.

D.* Eleven and a half years have now passed since the National Nutrition Conference for Defense was called by the President* of the United States. This meeting today brings that very successful oc- casion vividly to mind. By that time, May of 19^1, our defense efforts were well under way, and the great importance of nutrition in the program was clearly recognized« Enough was known about nu- trition to do something about it. Accordingly, more than 900 dele- gates met here in Washington to discuss the problem and to recommend a national course of action. I have just reviewed with a great deal of interest the recom- mendations made by that conference to
