Protein is a crucial component of a child's diet, and its significance becomes even more pronounced when considering malnourished children. Malnutrition is a condition characterized by a deficiency or imbalance of essential nutrients, which can lead to stunted growth, impaired development, and weakened immune system. Protein plays a pivotal role in addressing these issues and promoting overall health in malnourished children. Malnourished children often experience stunted growth, and apart from protein-rich diet sufficient kilocalories are required to support their catch-up growth and development. Optimal protein utilization needs sufficient calories in the diet of malnourished children. Without an appropriate calorie intake, the body may utilize protein as an energy source, which can hinder its primary role in tissue repair and growth. NDP Cal% is a way to evaluate the human diet to predict if protein need of an individual would be adequately met based on energy consumed. Dietary protein is expressed as percent of total calories rather than weight. Soybeans are one of the few plant-based protein sources that provide all the essential amino acids needed for human health and is more affordable than animal-based products like meat and dairy. This cost-effectiveness can be crucial for families with limited resources, making it easier to incorporate soy-based foods into the diet of malnourished children. In addition to protein, soybeans are rich in essential nutrients, including vitamins (e.g., B-vitamins) and minerals (e.g., iron, calcium). These nutrients are essential for overall health and can help address nutrient deficiencies common in malnourished children. Present study calculated the NDP Cal% of a nutrient dense soy product (Laddoo) which is developed by CIAE Bhopal. The efficacy of protein estimated by intervening the product to MAM children enrolled in Anganwadi centres of Bhopal District.
