Recommended Dietary Allowance

The Recommended Dietary Allowance (RDA), pronounced /ɹɪˈkɑːmɛndɪd daɪəˈtɛɹi əˈlaʊəns/, is the average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (approximately 98 percent) healthy individuals in a particular life stage and gender group. The term was first coined in the United States in 1941 by the National Academy of Sciences.

Etymology

The term "Recommended Dietary Allowance" is derived from the English language. "Recommended" comes from the Latin word "recommendare", meaning to entrust or commit to one's care. "Dietary" is derived from the Latin word "diaeta", meaning a way of life, and "Allowance" comes from the Old French word "alouer", meaning to grant or assign.
