Distribution of observed intakes

The observed dietary or nutrient intake distribution representing the variability of observed intakes in the population of interest. For example, the distribution of observed intakes may be obtained from dietary survey data such as 24-hour recalls.

Distribution of requirements

The distribution reflecting the individual-to-individual variability in requirements. Variability exists because not all individuals in a (sub) population have the same requirements for a nutrient (even if individuals are grouped into homogenous classes, such as Hispanic men aged 19 to 50 years).

Distribution of usual intakes

The distribution of long-run average dietary or nutrient intakes of individuals in the population. The distribution should reflect only the individual-to-individual variability in intakes. Statistical procedures may be used to adjust the distribution of observed intakes by partially removing the day-to-day variability in individual intakes, so the adjusted distribution more closely reflects a usual intake distribution.

Dose-response assessment

Determines the relationship between nutrient intake (dose) and either some criterion of adequacy or adverse effect.

DRI

Dietary Reference Intake; a reference value that is a quantitative estimate of a nutrient intake. It is used for planning and assessing diets for healthy people.

EAR

Estimated Average Requirement; a nutrient intake estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group.
