The Mediterranean Diet (MD) is globally and historically recognised as the most health-promoting dietary pattern in various clinical contexts and physiological conditions. Of interest, the MD is not only a sustainable dietary pattern that includes elements recognized as distinctive, such as seasonality, conviviality, culinary activities, biodiversity, traditional local and eco-friendly food products, but also a healthy lifestyle characterized by adequate levels of physical activity. This may be the case for sportspeople/athletes, whose nutritional needs often lead them to adopt particular/extreme dietary approaches or away from Mediterranean style. Recommendations of sports nutrition (SN) and MD characteristics can be combined or, at least, mutually adapted in athletes' diets, making them Mediterranean-style while meeting their nutritional needs. These nutritional aspects can be adapted by promoting a Mediterranean-type dietary pattern through the regular consumption of typical and traditional local foods. In this sense, the Campania Region boasts the largest number of registered traditional products in Italy (source from Regional Agriculture Department), including plant-based products with significant nutritional value and marked nutraceutical potential, which can sometimes minimise the need for supplementation. Examples are cultivars of cereals, legumes, potatoes, and chestnuts as important carbohydrate sources for sportspeople or typical varieties of maize, beans or dairy products as important source of leucine, fundamental for stimulating muscle protein synthesis. Equally noteworthy is the abundance of phytochemicals in many typical foods and agrifood by-products. Additionally, the use of typical and traditional products outlines the sustainability and low environmental impact of the MD, as it can significantly reduce resource consumption and environmental footprint. The MD, based on regular consumption of Mediterranean region's traditional foods, thus, may represent a good example of sustainable food model that can also be applied to SN, and its use should be encouraged in order to respect the environment and valorise the excellence of our territories.
