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
