In nutrient guidelines, what does AI stand for?

• A. Adequate Intake
• B. Actual Intake
• C. Average Intake
• D. Acceptable Intake

Answer: (A)

In nutrient guidelines, the term Adequate Intake is used. It’s a value established when there isn’t enough evidence to set an Estimated Average Requirement or a Recommended Dietary Allowance. Adequate Intake is based on observed intakes by healthy people or on experimental data and serves as a goal for daily intake to ensure nutritional adequacy when more precise data aren’t available. It’s a best estimate rather than a precise requirement, and you’d use it as a planning target or to evaluate whether typical intakes are likely sufficient. It’s different from Actual Intake, Average Intake, or Acceptable Intake, which are not the terms used in this context.
