The Mediterranean diet is the most studied dietary pattern with proven health benefits, especially regarding the prevention of non-communicable diseases at a time when their incidence is increasing worldwide. It has also been recognized as a sustainable diet model with multiple interdependent benefits on social, cultural, environmental, and economic dimensions. Faced with the challenge of promoting adherence to the Mediterranean diet, a Joint Med Diet Task Force of CIHEAM, FENS, and IUNS was formed to set the path for reversing the erosion of the Mediterranean diet heritage, by promoting its benefits, as a way of living, as defined by UNESCO.
