Abstract: The relationship between food prices and life expectancy in emerging countries has significant implications for public health and socioeconomic development in these regions. This study examines this relationship using a dataset of 120 emerging economies over the period 2000–2021, employing the dynamic panel threshold and system generalized method of moments (GMM) models. Our findings reveal a nonlinear inverted U‐shaped relationship where beyond a specific threshold, higher food prices tend to shorten life expectancy. We also reveal the disproportionate burden placed on low‐income countries when food prices rise, in comparison to middle‐income countries and highlight the profound impact of economic disparities on public health. Moreover, we identify several channels through which food prices affect life expectancy. Specifically, we reveal that income, undernutrition, and mental health disorders represent potential mediating factors affecting food prices–life expectancy nexus. We also shed light on the severe implications of economic crises on public health, emphasizing the close connection between economic events and indicators of human health. These insights have direct implications for policymakers, offering valuable guidance in the context of fluctuating food prices.
