RESUMO
The aim of this study was to present a new model for the Mediterranean Diet definition and to identify the major trends for the use of the Mediterranean Diet concept by 2028, in Portugal. A Delphi panel was implemented with 28 experts with solid knowledge and understanding of the Mediterranean Diet concept. The first round evaluated the degree of expert self-knowledge, which also contributed to the final questionnaire building. It was answered in 2 successive rounds with 21 statements, divided into 2 dimensions: Mediterranean Diet concept and use. A Mediterranean Diet model definition was produced with 73.8% of agreement. Culture, education, environment, health, food industry/distribution and tourism were identified as the future trends of Mediterranean Diet use areas. The model presented can be used as a pedagogical tool. For the first time, it was possible to explore the future trends of Mediterranean Diet use, which can help with the initiatives to safeguard the Mediterranean Diet concept.
