AMDR stands for what?

• A. Acceptable Macronutrient Distribution Range
• B. Dietary Reference Intakes
• C. Estimated Energy Requirement
• D. Adequate Intakes

Answer: (A)

AMDR stands for Acceptable Macronutrient Distribution Range. It defines the recommended percentage of daily calories that should come from carbohydrates, fats, and proteins to support health. Expressing macronutrients as a percent of energy allows flexible meal planning while meeting overall nutrient needs. Typical ranges guide how much of each macronutrient to consume, such as carbohydrates around 45–65% of calories, fats about 20–35%, and protein roughly 10–35%, though exact values can vary slightly by guideline. This concept sits within the Dietary Reference Intakes, the larger set of nutrient recommendations. Other terms—Estimated Energy Requirement is the average daily energy needed to maintain energy balance, and Adequate Intakes are used when there isn’t enough evidence to set an RDA.
