What does the estimate average requirement (EAR) indicate?

The estimated average requirement (EAR) is specifically designed to reflect the average energy and nutrient needs of a population. It is calculated to meet the needs of about half of the individuals within a certain demographic, often based on age, sex, and activity level. The EAR serves as a benchmark for nutritional adequacy, helping to identify dietary needs for proteins, vitamins, and minerals among other nutrients.

Choosing the average energy needs emphasizes that the EAR provides guidance on how much of certain nutrients is necessary for optimal health, channeling focus on nutrition planning for groups rather than individuals. This aids in assessing dietary sufficiency and making recommendations for dietary intake in populations, rather than specific quantities or recommendations related to food avoidance or hydration needs.
