This study aimed to investigate the impact of logistics performance, domestic food price, and food loss on diet diversification and depth of food deficit, as well as the impact of diet diversification and depth of food deficit on the prevalence of undernourishment worldwide. This investigation adopts a quantitative approach based on available data obtained from the Food and Agriculture Organization (FAO), the Global Food Security Index, and the World Bank Group. This study uses correlation analysis and multiple linear regression analysis as the analytical procedures. In a global perspective, evidence suggests that weak logistics performance tends to increase food loss, and domestic food price has a significant impact on diet diversification, as well as the domestic food price implies a significant increase in depth of food deficit in the world’s populations. Food price is the factor that most impacts the prevalence of undernourishment, severely affecting diet diversification and depth of food deficit worldwide. Reducing food prices has the potential to promote greater diet diversification for populations worldwide, contributing to promote global food security. This study highlights the necessity to develop an improved and efficient global food system, capable of reducing food prices, promote a cleaner food production and deliver improved nutrition and health for world populations. This investigation sustains that food price severely impacts the prevalence of undernourishment, affecting diet diversification and depth of food deficit worldwide.
