The Mediterranean diet: A historical perspective on food for health

The Mediterranean diet (MedDiet) represents the crystallisation of the centuries-old cooking legacies of different civilisations. The association of the MedDiet with longevity and low cardiovascular risk prompted the Seven Countries Study, which provided epidemiological evidence on the health effects of diet. This led to further studies, both epidemiological and interventional. Scales to measure adherence as well as studies of food components have consolidated a body of knowledge that is of great interest to institutions and governmental agencies. The recognition of its benefits for health has made the widespread introduction of the MedDiet an urgent challenge. Parallel efforts are being made to extend research through experimental and clinical studies. The purpose of this review is to present the historical background of the MedDiet, the main steps leading to the recognition of its health benefits, and the current strategy to facilitate its global implementation.
