Adequate intake
Adequate Intake (AI)
Adequate Intake (pronunciation: ad-uh-kwit in-teyk) is a Nutrient intake recommendation set by various nutrition research bodies when there is not enough evidence to establish a Recommended Dietary Allowance (RDA).
Etymology
The term "Adequate Intake" is derived from the English language. "Adequate" comes from the Latin word "adequatus" meaning "equal to, sufficient," and "Intake" is derived from the Old English "intacian" meaning "to take in."
Definition
Adequate Intake is the recommended average daily nutrient intake level based on observed or experimentally determined approximations or estimates of nutrient intake by a group (or groups) of healthy people that are assumed to be adequate. It is used when an RDA cannot be determined.
Application
Adequate Intake levels are often used in Dietary Reference Intake (DRI) systems, including those in the United States and Canada. They are set for macronutrients, micronutrients, water, and dietary fiber.
