Recommended Daily Allowances
A term used to denote recommendations for 26 nutrients for 18 different population subgroups. RDAs are based on information on nutrient allowances for healthy people from the National Research Council of the National Academy of Sciences. In 2005, a broader set of dietary reference values, known as the Dietary Reference Intakes (DRIs) replaced the RDA and RNIs intended to help individuals optimize their health and prevent disease. This information is revised about every five years and is used to determine the Daily Value and Reference Daily Intake figures used on food labels.
