Harmonizing Micronutrient Intake Reference Ranges for Dietary Guidance and Menu Planning in Complementary Feeding

Abstract

ABSTRACT There are no published harmonized nutrient reference values for the complementary feeding period. The aim of the study was to develop proposals on adequate and safe intake ranges of micronutrients that can be applied to dietary guidance and menu planning. Dietary intake surveys from 6 populous countries were selected as pertinent to the study and reviewed for data on micronutrients. The most frequently underconsumed micronutrients were identified as iron, zinc, calcium, magnesium, phosphorus, potassium, and vitamins A, B6, B12, C, D, E, and folate. Key published reference values for these micronutrients were identified, compared, and reconciled. WHO/FAO values were generally identified as initial nutrient targets and reconciled with nutrient reference values from the Institute of Medicine and the European Food Standards Authority. A final set of harmonized reference nutrient intake ranges for the complementary feeding period is proposed.
