Which statement about AI (Adequate Intake) is true?

• A. It represents the average daily intake to meet needs.
• B. It is used to plan intakes for athletes.
• C. It is the maximum daily intake unlikely to cause adverse effects.
• D. It is used when RDI cannot be determined.

Answer: (D)

Adequate Intake is a value used when there isn’t enough evidence to establish a precise requirement or to set an RDI/RDA. It represents a level of daily intake that appears to sustain health for a group, based on observed intakes or experimental data, and it serves as a guide when the data are insufficient to determine an EAR/RDA. That’s why this statement—useful when the usual RDI cannot be determined—is the best fit. The other descriptions fit other reference values: the idea of an average daily intake to meet needs is more aligned with how RDAs are defined, planning for athletes uses general dietary guidelines rather than AI, and the notion of a maximum daily intake corresponds to the Upper Intake Level (UL).
