This study was undertaken to develop a computer software program to analyze dietary data in terms of food groups and nutrients using a personal computer compatible with IBM PC 386. this program consisted of three functions. The first function was calculating the food intakes from each food group and evaluating the dietary status by comparing then with the constituted food amounts. The second one was calculating energy and nutrient intakes from each food group and evaluating the status of dietary intake by comparing the nutrient intakes with the recommended dietary allowance. The third function was calculating and evaluating the status of nutrient intakes and the energy composition rate by each meal and snack. The results were displayed in tabular forms and graphical forms on the computer screen.
