Food security is the key element of the mental and physical health of the community. So, accurate and comprehensive attention to this issue and recognize a multidimensional index to cover all aspects of food security is important to economic and political interdependence – in addition to economic aspects- for researchers and policymakers. Therefore, the aim of this study was to introduce and calculate a new index to estimate the food security level with GFSI index during 1980- 2013. Also, the food security situation during five years development programs descriptively and impact of price indexes and population on food security by ARDL model and Bound test were studied. The result showed that the food security fluctuates during the time. Especially food security enhances more during 1th and 4th five- year development plan. Also, the result showed the level of prices and population as negative factors on food security in short and long term.
