RDA is RECOMMENDED DIETARY ALLOWANCE. It is the estimated amount of a nutrient (or calories) required per day considered necessary for the maintenance of good health by Food and Nutrition Board of National Research Council/National Academy of Sciences.

Answer 2

The process for setting the RDA depends on being able to set an Estimated Average Requirement (EAR). That is, the RDA is derived from the nutrient requirement so if an EAR cannot be set, no RDA will be set. . The RDA for a nutrient is a value to be used as a goal for dietary intake by healthy individuals.
