  Purpose

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.

Primary Outcome Measures:
  • micronutrient status [ Time Frame: 6 months intervention study with baseline and endpoint data collection ] [ Designated as safety issue: No ]
    change in micronutrient status (hemoglobin and serum concentrations of vitamin D, calium, zinc) from baseline to end of the intervention when children have received the food bar for 6 months, 5 days/week.


Secondary Outcome Measures:
  • cognitive function [ Time Frame: 6 months intervention study with baseline and endpoint data collection ] [ Designated as safety issue: No ]
    change in cognitive function (as measured by Raven's test) in children from baseline to end point, when the children have received 6 months of food bar, 5 days/week
