This study is a randomized controlled clinical trial, and 106 children will be studied for eight weeks. Inclusion criteria are having age 24 to 59 months; mild and moderate malnutrition without edema (Anthropometric index of weight for height between the -1 and -3 z-score); filling a consent form. Exclusion criteria are being twins; food allergies and intolerance; severe anemia; liver-kidney disease; malabsorption syndrome; unwillingness to cooperate. After enrollment, children will be allocated into two groups (Intervention and Control groups) based on random number table. Intervention group will receive the formula and the control group on the other will not. At baseline and during examination sessions, caregivers will be trained about Childhood nutrition. Before initiating the intervention, we will ask caregivers to give 5 grams of sample to children in the intervention group in case of checking for food intolerance. In absence of food intolerance, we will measure and record their weight, height and weight for height anthropometric index. In addition, during examination sessions, we will ask questions about the frequency of symptoms such as diarrhea, anorexia and abdominal pain. Also, we will take two Food records from caregivers which will show food consumed by children. After intervention we will measure and record their weight, height and weight for height anthropometric index. The primary outcome will be recovery (Increment of children's weight for height anthropometric index to the top of -1 z-score). The Secondary outcomes will be average increment of weight gain, height gain, and incidence of fever and diarrhea among children.
