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.
