Dietary Assessment Summary

Dietary Assessment Summary
For nutrients with a(n) For Dietary Assessment of Individuals For Dietary Assessment of Groups
Note: An individual's usual intake should be used. Observed mean intake over a few days may not be sufficiently accurate. Note: Intake distributions must be adjusted to account for variation in usual intakes among individuals and the day-to-day within-individual intake variation.
EAR The EAR is the best estimate of an individual's requirement.

Usual intake below the EAR very likely needs to be improved (the probability of adequacy is 50% or less).

Usual intake between the EAR and the RDA probably needs to be improved.
Use the EAR to assess the prevalence of inadequate intakes.
RDA Usual intake at or above the RDA has a low probability of inadequacy. Do not use the RDA (or a group mean intake) to assess nutrient adequacy of groups.
AI Usual intake of the nutrient at or above the AI has a low probability of inadequacy.

Usual intake below the AI cannot be assessed.
Mean usual intake of the nutrient at or above the AI implies a low prevalence of inadequate intakes of the nutrient.

Mean usual intakes below the AI cannot be assessed.
UL Usual intake above the UL places an individual at potential risk of adverse effects from excessive intake of the nutrient. Use the UL to estimate the percentage of the group at potential risk of adverse health effects from excessive nutrient intake.

EAR = Estimated Average Requirement
RDA = Recommended Dietary Allowance
AI = Adequate Intake
UL = Tolerable Upper Intake Level
