Abstract

In 1983, 27 million in the U.S. population (11.7%) were over 65 years of age, and by the year 2050 this number is expected to be nearly double (U.S. Census of Population, 1980). In view of this projection, there is concern for maintaining health and function as late as possible into an individual’s life span. In the maintenance of health and prevention of disease, adequacy of nutrition is an important component. At different stages of life, sufficiency of intakes of nutrients is prescribed by the recommended dietary allowances (National Academy of Sciences, 1980), which have been defined as “the levels of intake of essential nutrients considered, in the judgment of the Committee on Dietary Allowances of the Food and Nutrition Board on the basis of available scientific knowledge, to be adequate to meet the known nutritional needs of practically all healthy persons.” The basis for this definition is discussed in Chapter 1. In the case of adults, the 1980 RDAs are divided into two age categories, namely, 23–50 years and 51 years upwards. It is, however, unlikely that the nutrient requirements of a 50-year-old adult are the same as those of a person of 23 years, and it is even more improbable that a person of 90 years has the same needs as an individual aged 51 years. Acceptance of these broad categories for RDAs underlines the paucity of data on which to base narrower age bands.
