摘要：Sustainable diets concept has recently gained an increased momentum. The sustainability of food systems and diets is not simply related to health concerns as it also involves environmental impacts. The paper aims at analysing the environmental cost of non-adherence to the Mediterranean dietary pattern in from a water footprint perspective. The water footprint of the current Italian food consumption pattern is compared with North American and Scandinavian ones as well as with the proposed food Mediterranean dietary pattern i.e. the diet (MD). The paper is mainly based on secondary data from different sources (e.g. FAOSTAT; Water Footprint Network). According to FAOSTAT, food supplies in (3649 kcal/capita/day) and the (3766 kcal/capita/day) are slightly higher than in (3217 kcal/capita/day). The share of plant-based energy in the diet in (74.2%) and the (72.6%) is higher than in (63.5%). The average water footprint of an Italian citizen (1848.29 m3/capita/year) is 65.5% higher than a Finnish one (1116.69 m3/capita/year) but 15.9% lower than that of a North American citizen (2198.66 m3/capita/year). Meat and dairy products represent more than a half of the total water footprint of food supply. The water footprint of the current Italian dietary pattern is 69.9% higher than that of the proposed diet. That’s to say that a 100% adherence of the Italian population to the proposed Mediterranean diet from 2006 to 2011, would have allowed an estimated saving of about 152,749 million m3 of water; corresponding to total freshwater abstraction for about three and half years. Adherence of the Italian population to the Mediterranean dietary pattern can bring about not only significant health benefits but also reduces the food environmental footprint on natural resources especially water consumption.
