Food variety score (FVS) was estimated in the range of 5-38, by counting the food items which have been consumedat least 40 grams in an average week (Except in the case of fats and sweets) then it was calculated on a daily basis. Subjects in this study was categorized into 4 groups based on FVS; Very poor, poor, relatively favorable and favorable. Consumption of any items from each food groups at least once per day was considered to estimate the dietary diversity score (DDS). Results:Mean age and BMI of the subjects was 35/3±11/7 year and 33/01±5/03 kg/m2respectively. More than subjects (90/8%) consume each of the seven food groups daily and the eliminated groups from the daily diet were dairy and miscellaneous groups (including drinks, sweeteners and yeast). 92/2% of subjects consume from grain group, 29/1% from fruits, 27/6% from vegetables and 19/2% from meat group, at least one subcategoryfrom each group. Range of FVS was 5-38, mean and median of FVS was 24/3 and 24respectively. Only about 22/7% of subjects have the favorable food varietyscore (FVS>28). Discussion: Results from this study indicated that only a few of the subjects in this study have favorable food variety status and knowledge promotion is required to improve nutrition and health status.
