Introduction: The incidence of undernutrition among children is high in India, which will pave its way to the occurrence of frequent infection, reduced learning capacity, poor academic performance and cognitive deficit. The health mix is the most popular, convenient, easy to prepare and healthy dish for the children. Objective: To develop a cheaper and nutritious health mix for improving the nutritional status and cognitive function in children. Method: The raw ingredients were procured, processed, powdered and mixed into 5 variations of health mix. The developed health mixes were analysed for their nutritional and sensory qualities. Result: The results stated that the health mix 3 with the combination of multi-grain such as red rice (25g), Bajra (25g), Green gram (20g), Soybean (10g), Rice flakes (10g), Jaggery (8g) and Brahmi leaves (2g) received significantly higher scores and also selected as best in having a high amount of essential nutrients namely, protein (14.9 g), fat (1.68 g), iron (6.52 g), zinc (1.91 mg), selenium (445 mg) required for the improvement of nutritional status and cognitive function. Health 3 has got the highest rating in many sensory qualities and also the results were similar to the control sample. Conclusion: Our study indicates the importance of a healthy mix, prepared from the combination of multi-grains with Brahmi leaves, as one of the most convenient food formulas for supplementation to undernourished children. Future studies on such supplementation to improve the nutritional status and cognitive function of undernourished children is recommended.
