Nutritional Guidelines Definitions

Study Notes

Dietary Reference Intakes (DRI)

DRI is a comprehensive guideline for daily nutrient intake.
It includes recommended daily allowances (RDA), adequate intake (AI) values, and tolerable upper intake levels (UL).
Covers essential nutrients such as vitamins, proteins, fats, and fiber.

Recommended Dietary Allowance (RDA)

RDA refers to the daily intake level of a nutrient necessary for health maintenance.
Aims to prevent deficiencies in vitamins and nutrients.
Is based on scientific research to determine optimal nutrient levels for a healthy population.

Estimated Average Requirement (EAR)

EAR represents the mean nutrient requirement for a population group.
Used to assess the adequacy of nutrient intakes for researchers and health professionals.
Provides a statistical basis for RDA development.

Adequate Intake (AI)

AI is an average nutrient intake level deemed adequate based on observational data or experimental findings.
Applicable when RDA cannot be determined due to lack of data.
Reflects the observed nutrient intake by healthy individuals.

Upper Limit (UL)

UL identifies the maximum daily intake of a nutrient unlikely to cause adverse health effects.
Applies to supplements and enriched foods.
Helps prevent toxicity from excess consumption of nutrients.
