Dietary Reference Intakes (DRI)

Dietary Reference Intakes (DRIs) are evidence-based guidelines that specify the ideal amounts of nutrients needed for health, growth, and well-being for different age groups and genders. They help individuals and health professionals determine appropriate daily nutrient intake to prevent deficiencies and reduce the risk of chronic diseases. DRIs include several components—Recommended Dietary Allowance (RDA), Adequate Intake (AI), Tolerable Upper Intake Level (UL), and Estimated Average Requirement (EAR)—each serving a specific role in nutritional planning and assessment. These guidelines support informed dietary choices for maintaining overall health.
