recommended dietary allowance

(rĕk′ə-mĕn′dĭd)
n. Abbr. RDA
The amount of a nutrient or the amount of calories recommended for a person to consume daily, especially the amount of specific vitamins and minerals recommended by the Food and Nutrition Board of the National Academy of Sciences.

recommended daily allowance

Any of the guidelines produced by the Food and Nutrition Board of the National Research Council (US) for the amount of a vitamin, mineral or other essential nutrient that should be ingested every day by a normal person engaged in average activities. RDAs are increased for increased activity, body growth and size, pregnancy, lactation, and adverse environmental conditions; RDAs assume a state of wellness and are poorly applicable in sick, traumatised and/or burned patients.

A criticism of the RDA is that it was established by the US Food and Nutrition Board in 1941, at a time when sound dieting practices were rare and nutritional deficiencies not uncommon. Malnutrition is now rare in the US, as many foods are supplemented with the necessary vitamins and minerals; many nutritionists now prefer the Daily Value standard.
