DIETARY REFERENCE INTAKE (DRI)

• Comprises a set of four nutrient-based reference values being developed by the Food and Nutrition Board (FNB) of the National Academy of Sciences.

• These values are intended to replace and expand on the familiar RDA

• Can be used for planning and assessing diets

DRI

Dietary reference intake

four nutrient-based reference values

1. Recommended Dietary Allowance

2. Estimated Average Requirement

3. Adequate Intake

4. Tolerable Upper Intake Level

RECOMMENDED DIETARY ALLOWANCE

• RDA of a nutrient is the average daily intake needed to meet the requirements of virtually all healthy people in a given life stage or gender group

• Prevents nutritional deficiency rather than promotes optimal health

RDA means:

RECOMMENDED DIETARY ALLOWANCE

Estimated Average Requirement (EAR)

• Is the average dietary intake needed to meet the requirements of half of all healthy people in a given life stage or gender group

• Determination of this value isn't based solely on preventing

nutritional deficiency

EAR means

Estimated Average Requirement

Adequate Intake (AI)

• Assigned to a nutrient if the FNB lacks sufficient information to establish an RDA and an EAR

• Recommended daily intake level based on estimates of nutrient intake by a group healthy people

AI means

Adequate Intake

Tolerable Upper Intake Level (UL)

• Is the highest level of nutrient intake that doesn't cause

adverse health effects in most individuals in the general

population.

(UL) means

Tolerable Upper Intake Level
