REFERENCE DAILY INTAKES (RDIs) A new term that replaces the familiar U.S. Recommended Daily Allowances (U.S. RDAs). RDIs are based on a population-weighted average of the latest RDAs for vitamins and minerals for healthy Americans over 4 years old. RDIs are not recommended daily intake figures for any particular age group or sex. They are simply average values for the entire population.

The RDI for protein for everyone over 4 years of age is 50 grams and, for those under 4, is 14 grams. For vitamins and minerals. RDIs are:
