  1. DG, tentative dietary goal for preventing lifestyle-related diseases; DRIs, Dietary Reference Intakes for Japanese; EAR, estimated average requirement; NHNS, National Health and Nutrition Survey in Japan.
  2. † Highest value among the reference values (DG for total fibre and potassium, and EAR for vitamin A) of adults for each nutrient in the Dietary Reference Intakes for Japanese.
  3. ‡ Nutrient intake from fruit of Japanese adults who participated in the NHNS when classified into two groups using the fruit intake set in the scenario as a cut-off.
  4. § The value obtained by subtracting the nutrient intake from non-fruit foods and the scenario-based nutrient intake from fruit among Japanese adults who participated in NHNS 2019 from the DRIs reference values.
  5. Vegetable intake required to meet the reference values during the vegetable intake patterns observed in the NHNS 2019.
  6. †† The estimated average intake of fruit when consumed in the scenario.
