Dietary Reference Intakes for Koreans (KDRIs).

Abstract

For more than 40 years, Recommended Dietary Allowances for Koreans (KRDA) were used as references for nutrient intake. In 2002, the Korean Nutrition Society organized a committee to revise the KRDA, which were transformed into the new Dietary Reference Intakes for Koreans (KDRIs) in 2005. KDRIs include Estimated Average Requirements (EAR), Recommended Intake (RI), Adequate Intake (AI) and Tolerable Upper Intake Level (UL) for protein, essential amino acids and micronutrients, Estimated Energy Requirement (EER) for energy and Acceptable Macronutrients Distribution Ranges (AMDR) for macronutrients. Evidence-based methods were used to determine the reference value (s) and the levels of nutrient intake for each nutrient. The KDRIs expanded significantly the number of nutrients and the basic concepts of nutrient recommendations compared to the previously used KRDA. In addition, a new food guide, depicted as Food Tower for Koreans, was developed and appended to the KDRIs publication. Continued efforts are needed to facilitate the application of KDRIs as well as to improve the understanding of the concepts. Additional modifications will be made as more scientific data become available.
