The RDA allowances, expressed as average daily intakes over time, are
intended to provide for individual variations among most normal
persons as they live in the United States under usual environmental
stresses.
Diets should be based on a variety of common foods in order to
provide other nutrients for which human requirements have been less
well defined.
