Research Needs for Establishing Dietary Guidelines for the U.S. Population

摘要

This report attempts to identify priorities for research in nutrition, seeking new information needed for the development of dietary recommendations for the public. No single recommendation to the public regarding appropriate intakes of energy, protein, fat, carbohydrates, and sodium could be made. Needs for energy and essential nutrients vary with age, sex, physiological state, heredity, and physical activity. Therefore, many of the research needs identified in this report pertain to problems specific to subgroups of the population for whom unique guidelines are required. The report deals with the state of knowledge and research needs pertinent to the establishment of dietary guidelines for intakes of total calories, sodium, carbohydrates, lipids, and proteins.
