What is the AMDR defined as?

• A. A range equal to the Tolerable Upper Intake Level for a nutrient
• B. A range of intake for a particular energy source that is associated with a reduced risk of chronic disease while providing adequate intakes of essential nutrients
• C. The Recommended Dietary Allowance for a nutrient
• D. The Estimated Average Requirement for a nutrient

Answer: (B)

The Acceptable Macronutrient Distribution Range defines the recommended range of daily energy intake that should come from each macronutrient to support nutrient adequacy and lower chronic disease risk. It’s expressed as a percent of total energy, not as fixed gram amounts. For example, carbohydrate usually should provide about 45–65% of total calories, fat about 20–35%, and protein about 10–35%. This contrasts with numbers like the UL (maximum safe intake), or the RDA/EAR (absolute intake targets for micronutrients), which are not distributions of energy.
