What is the primary purpose of Dietary Reference Intakes (DRIs)?

• A. To set minimum dietary requirements for all populations.
• B. To provide reference values used for planning, assessing, and evaluating nutrient intakes.
• C. To determine upper limits for nutrient supplements.
• D. To measure daily energy expenditure.

Answer: (B)

DRIs provide reference values to guide how much of each nutrient people should aim for, and they’re used to plan, assess, and evaluate intakes for healthy individuals across different life stages and sexes. These reference values help determine nutrient goals for individuals and populations, identify whether typical diets meet those goals, and judge whether intakes are adequate or excessive. DRIs include elements such as estimated average requirements, recommended dietary allowances, adequate intakes, and tolerable upper intake levels, and they’re tailored to different ages and life situations. They’re not simply minimum requirements for everyone, nor do they measure daily energy expenditure.
