Answer to Question 1

Recommended Dietary Allowances (RDA): a set of values reflecting the average daily amounts of nutrients considered adequate to meet the known nutrient needs of practically all healthy people in a particular life stage and gender group; a goal for dietary intake by individuals.
Estimated Average Requirements (EAR): the average daily nutrient intake levels estimated to meet the requirements of half of the healthy individuals in a given age and gender group; used in nutrition research and policymaking and as the basis on which RDA values are set.

The RDA is set high enough to cover nearly everyone's nutrient requirements, without being too high as to approach toxicity. The EAR is an average intake level; that is, adequate to meet the requirement of half of the population (see Figure 1-2).
