The objective of the study is to evaluate the impact of the milk-based nutrient-rich bar, specifically the effect of its fortification with zinc, iodine, vitamins A and D and calcium on nutritional status of school children, focusing on vitamin A and, zinc, iodine, calcium and iron status, and on their cognitive performances.
Design: double-masked randomized control trial Place: three schools in South Vietnam, Can Tho district, South Vietnam Subjects: School children aged 6 to 10 years old, from first grade to third grade of 3 primary schools. Duration of intervention: 6 months (consumption of Goody or "control bar") Study groups: 2 groups: Group 1: children will receive micronutrient enriched milk bar.
