NUTRITN 230 Lecture Notes - Lecture 4: Dietary Reference Intake, Dietary Fiber, Body Composition
Document Summary
The dris include four different sets of reference values. Intakes that meet the estimated nutrient needs of 50% of individuals in a sex and life-stage group. Used to evaluate the adequacy of the nutrient intake of population groups. Individual at a specific life stage and sex. Intakes that are sufficient to meet the nutrient needs of almost all (97-98%) healthy people in a specific life-stage and sex. Rdas are based on the ears (rda = ear x 1. 2) therefore can only be set for nutrients with an ear. Higher than the average human needs to account for variability. Risk of deficiency is low if rda met and increases as intake falls below rda. For not enough research to set an rda or ear. Used when there is inadequate research data to establish an ear or. An approximation of the average nutrient intake that appears to sustain a desired indicator of health.
