(RDA) Estimated average requirement (EAR) Adequate intake (AI) Tolerable Upper Limit (UL)
Estimated Average Requirement (EAR)
Amounts of nutrient estimated to meet the nutrient needs of 50% of the persons in a certain life stage .
For example adolescents or pregnant women.

Goal is to prevent chronic diseases
not just prevent deficiency
