Daily Reference Intakes (DRIs): A Comprehensive Guide

Daily Reference Intakes (DRIs) are recommended nutrient values per person per day. They are established by the Food and Drug Administration (FDA) to act as a guideline for healthy dietary intake for males and females of all age groups.

History

• RDIs are based on Recommended Dietary Allowances (RDAs). RDAs were determined during World War II to provide a paradigm for health for those in the armed forces as well as civilians. It was reviewed and updated every five to 10 years.

Use

• DRIs along with Daily Reference Values (DRV) are used in nutrition labels on food items. The percent Daily Value (DV) listed alongside the nutrition facts on the label is calculated in large part from the DRI.

Calculation

• DRIs are calculated using four reference values: Adequate Intakes (AI), Estimated Average Requirements (EAR), Recommended Dietary Allowances (RDA), and Tolerable Upper Intake Levels (UL). DRI is used interchangeably with Dietary Reference Intake (DRI).

Current Nutrition Recommendations

• Dietary Guidelines for 2005 recommend males and females between 19 and 30 consume 130g of carbohydrates, 25-38g of fiber, and 46-56g of protein. These values are subject to change depending on weight, age, and lifestyle.
