Food security is one of the main conditions for the realization of national security and one of the pillars of economic development. This is especially important in developing countries that do not have adequate food security. Thus, the aim of this study is the mathematical analysis of the impact of macroeconomic variables on food security and its sub-indicators (access to food, economic ability to buy food, and food health) in 64 developing countries. For this purpose, the panel data approach and data of developing countries during the period 1996-2016 have been used. The results showed that GDPs of countries have a positive effect on food security so that all the three dimensions of food security improve with increasing income. Rising prices will reduce food security by reducing access to food and reducing purchasing power. Increase in the value-added agricultural sector by improving access to food improves food security and increase in urbanization in different dimensions has different effects on food security which ultimately reduces food security.
