How Many? A Dictionary of Units of Measurement |
Data from the U.S. Food and Drug Administration's page, Daily Values Encourage Healthy Diet. The daily values fall in two groups, Daily Reference Values (DRVs) for energy-producing nutrients and Reference Daily Intakes (RDIs) for vitamins and minerals. The DRVs are based on 2,000 calories a day for adults and children over 4 only. The RDIs are based on the National Academy of Sciences's 1998 Recommended Dietary Allowances.
