What does RDA mean?
Recommended Dietary Allowances (RDAs) are the levels of intake of essential nutrients that, on the basis of scientific knowledge, are judged by the Food and Nutrition Board to be adequate to meet the known nutrient needs of practically all healthy persons.
What is a RDA in nutrition?
Recommended Dietary Allowance (RDA): average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy people. Adequate Intake (AI): established when evidence is insufficient to develop an RDA and is set at a level assumed to ensure nutritional adequacy.
How RDA is calculated?
The RDA is set at the EAR plus twice the standard deviation (SD) if known (RDA = EAR + 2 SD); if data about variability in requirements are insufficient to calculate an SD, a coefficient of variation for the EAR of 10 percent is ordinarily assumed (RDA = 1.2 x EAR).
What is the RDA for adults?
RDA refers to the minimum daily intake that fulfills the needs of almost all healthy people in a particular lifestage or group.

Why is RDA important?
The Recommended Dietary Allowance (RDA) is the value to be used in guiding healthy individuals to achieve adequate nutrient intake. It is a goal for average intake over time; day-to-day variation is to be expected. RDAs are set separately for specified life stage groups and sometimes they differ for males and females.
Why isn’t there an RDA or ear for water?
Because EAR and RDA values could not be established for daily water intake due to the large variation in water needs across the population, the IOM panel established AI values of 3.7 L/day in males (130 oz; the equivalent of 16 cups of fluid) and 2.7 L/day for females (95 oz; about 12 cups).
