pdri

The Food and Nutrition Research Institute of the Department of Science and Technology (FNRI-DOST) launches the PDRI 2015 during the opening ceremony of the 41st FNRI Seminar Series on July 1, 2015 at the FNRI Auditorium. The 2015 PDRI adopts the multi-level approach for setting nutrient reference values to meet the needs of various stakeholders for appropriate nutrient reference values.

This is for planning and assessing diets of healthy groups and individuals. PDRI is the collective term comprising reference value for energy and nutrient levels of intakes. The components of PDRI are:

  • Estimated Average Requirement (EAR): daily nutrient intake level that meets the median or average requirement of healthy individuals in particular life stage and sex group, corrected for incomplete utilization or dietary nutrient bioavailability.
  • Recommended Energy/Nutrient Intake (REI/RNI): level of intake of energy or nutrient which is considered adequate for the maintenance of health and well-being of healthy persons in the population.
  • Adequate Intake (AI): daily nutrient intake level that is based on observed or experimentally-determined approximation of the average nutrient intake by a group (groups) of apparently healthy people that are assumed to sustain a defined nutritional state.
  • Tolerable Upper Intake Level or Upper Limit (UL): highest average daily nutrient intake level likely to pose no adverse health effects to almost all individuals in the general population.


See PDRI Tables for details.
