The Reference Daily Intake or Recommended Daily Intake (RDI) is the daily intake level of a nutrient that is considered to be sufficient to meet the requirements of 97–98% of healthy individuals in every demographic in the United States (where it was developed, but has since been used in other places). The RDI is used to determine the Daily Value (DV) of foods, which is printed on nutrition facts labels (as %DV) in the United States and Canada, and is regulated by the Food and Drug Administration (FDA) and Health Canada respectively. The RDI is based on the older Recommended Dietary Allowance (RDA) from 1998; newer RDAs have since been introduced in the Dietary Reference Intake system, but the RDI is still used for nutrition labeling. == Food labeling reference tables == DVs used by the FDA for the following macronutrients are Daily Reference Values (DRV). The following table lists the DVs based on a caloric intake of 2000 kcal (8400 kJ), for adults and children four or more years of age. For vitamins and minerals, the RDIs are given in the following table, along with the more recent RDAs of the Dietary Reference Intakes (maximized over sex and age groups):〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Reference Daily Intake」の詳細全文を読む スポンサード リンク
