Adequate Intake
Adequate Intake
Adequate Intake (pronunciation: ad-uh-kwit in-teyk) is a term used in Nutrition and Dietetics to refer to the recommended amount of nutrients that a person should consume daily. It is often abbreviated as AI.
Etymology
The term "Adequate Intake" is derived from the English words "adequate" meaning sufficient or enough, and "intake" meaning the amount of food, drink, or other substances taken into the body.
Definition
Adequate Intake is a Dietary Reference Intake (DRI) established by the Food and Nutrition Board of the Institute of Medicine (IOM). It is used when there is not enough evidence to determine an Estimated Average Requirement (EAR) and calculate a Recommended Dietary Allowance (RDA). The AI is set at a level assumed to ensure nutritional adequacy.
