The Recommended Dietary Allowance (RDA) is the minimum amount required to avoid a deficiency. Recently, some of these figures were updated with a Dietary Reference Intake (DRI), which lists the amount required for optimal health (some experts still believe these have been set too low).

Not all nutrients have a DRI established. If no DRI or RDA has been determined, a Safe and Adequate Intake or Range (or estimate) is provided.
