Regional food consumption in Italy, a life cycle analysis

Urbanization and globalization have led to an increasing concern and focus on the sustainability of the food sector, particularly in discussing the composition of consumers' diets. This study examines Italian consumption habits, categorizing them into four macro-geographical areas (North-West, North-East, Center, South, and Islands), utilizing public data obtained from surveys including 3323 individuals, and assesses their environmental impacts through the application of the Life Cycle Assessment methodology. The findings unveil distinct dietary patterns across Italian macro-regions, indicative of cultural disparities, and present avenues for promoting environmentally sustainable dietary choices. The study identifies meat consumption as the primary environmental concern across all macro-regions, with fish emerging as a secondary contributor to particulate matter formation. Pork and poultry exhibit notable impacts within toxicity-related categories. Additionally, the research underscores challenges in data collection, notably the absence of a site-specific Italian database, and underscores the necessity for more recent consumption data to accurately capture contemporary Italian dietary habits. Finally, the study demonstrates that addressing the issue from a macro-regional perspective allows for more targeted and dedicated cultural interventions.
