This systematic review assesses 1) whether macro- and micronutrient requirements of children aged 6–23 months in low- and middle-income countries are met by the consumption of locally available foods (‘‘observed intake’’) and 2) whether nutrient requirements can be met when optimizing the use of local foods, using modeling techniques (‘‘modeled intake’’). Data from 23 articles indicate that children aged 6–23 months meet requirements of protein, while diets are inadequate in calcium, iron, and zinc; children did not always fulfill their requirements for energy, vitamin A, thiamin, riboflavin, niacin, folate, and vitamin C. No conclusions can be drawn for vitamin B6, B12, and magnesium due to the scarcity of available evidence.
