Dietary Reference Intake
From Free net encyclopedia
Dietary Reference Intake is a set of guidelines set up in 1997 to give more detailed guidance than the RDA system which preceded it. It was a collaboration between the USA and Canada.
The DRIs are a set of four reference values: Estimated Average Requirements (EAR), Recommended Dietary Allowances (RDA), Adequate Intakes (AI), and Tolerable Upper Intake Levels, (UL) that have replaced the 1989 Recommended Dietary Allowances (RDAs).
The name RDA was dropped in favour of Dietary Reference Intakes (DRIs).
It added three new categories:
- Adequate intake (AI), where no RDA has been established
- Estimated safe and adequate daily dietary intake (ESADDI), expected to satisfy the needs of 50% of the people in that age group.
- Tolerable upper intake levels (UL), to caution against excessive intake of nutrients (like vitamin D) that can be harmful in large amounts.
