Recommended Dietary Allowances
Recommended Dietary Allowances (RDA)
Recommended Dietary Allowances (RDA) /rɪˈkɒmɛndɪd daɪəˈtɛri əˈlaʊənsɪz/ is a system of nutritional guidelines developed by the Food and Nutrition Board of the National Academy of Sciences in the United States. The term was first used in 1943 and has since been updated periodically to reflect advances in nutritional science.
Etymology
The term "Recommended Dietary Allowances" is derived from the English words "recommend" (from the Latin recommendare, meaning 'to entrust'), "dietary" (from the Latin diaeta, meaning 'way of life, diet, regimen'), and "allowance" (from the Old French alouance, meaning 'recognition, admission').
Definition
The RDA is defined as 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. It is calculated based on the Estimated Average Requirement (EAR), with an added amount to accommodate variability in dietary needs among individuals.
