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.


It dropped the name RDA 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.

Nutritional studies with animals have shown that the amounts of some nutrients sufficient to provide health and the prevention of a deficiency disease for short periods of time may be totally inadequate to maintain the health of the animal over its entire lifespan.
