Question

Quizplus · Accepted Answer

Recommended Dietary Allowances (RDAs) are the foundation of Dietary Reference Intakes (DRIs), which provide a set of guidelines for nutrient intake. RDAs are set based on scientific data and aim to prevent deficiencies rather than toxicities, and they focus on all dietary components rather than just a few. Therefore, option D is the correct answer. Recommended Dietary Allowances (RDAs) are a part of the Dietary Reference Intakes (DRIs) and are the foundation of the DRIs. RDAs are nutrient intake goals for individuals and are set based on scientific evidence to meet the needs of 97-98% of healthy individuals in a specific age and gender group. RDAs focus on all dietary components necessary for optimal health and are set to prevent deficiencies, not toxicities. Adequate Intake (AI) values are set when there is a lack of scientific data to derive an RDA.
