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
