Food, after air and water, is considered the most vital need for human survival, and today access to healthy food is increasingly facing difficulties. Food security, meaning sustainable and sufficient access to nutritious and healthy food sources, has gained growing importance, and in recent decades, Iran has encountered multiple challenges in this regard; the second Sustainable Development Goal is also to ensure sufficient, healthy, and affordable food for all. The present study aims to examine the impact of macroeconomic variables, especially the inflation rate, on food security in Iran during the years 1983 to 2022. For this purpose, a vector autoregression (VAR) approach was employed. The results indicate that inflation shocks have led to a decrease in food security, although this effect gradually diminished starting from the third period. Furthermore, economic growth shocks initially exert a negative impact on food security, but over time this effect shifts toward positive and eventually diminishes, showing a moderated influence. In addition, positive shocks in the real exchange rate are entirely associated with a negative response in food security; this reaction intensifies approximately up to the fourth period, then gradually declines and converges to zero. Finally, income inequality shocks initially have a negative effect on food security, but later this effect becomes positive and its intensity gradually decreases, ultimately moderating over time. Overall, the findings of this study confirm that establishing economic stability and adopting appropriate macroeconomic policies play a crucial role in improving and maintaining food security in the country.
