The growing impact of chronic degenerative pathologies (such as cardiovascular disease, type 2 diabetes and Alzheimer’s disease) requires and pushes towards the development of new preventive strategies to reduce the incidence and prevalence of these diseases. Lifestyle changes, especially related to the Mediterranean diet, have the potential to modify disease outcomes and ultimately costs related to their management. The objective of the study was to perform a systematic review of the scientific literature, to gauge the economic performance and the cost-effectiveness of the adherence to the Mediterranean diet as a prevention strategy against degenerative pathologies. We investigated the monetary costs of adopting Mediterranean dietary patterns by determining cost differences between low and high adherence. Research was conducted using the PubMed and Scopus databases. Eight articles met the pre-determined inclusion criteria and were reviewed. Quality assessment and data extraction was performed. The adherence to the Mediterranean diet has been extensively reported to be associated with a favorable health outcome and a better quality of life. The implementation of a Mediterranean dietary pattern may lead to the prevention of degenerative pathologies and to an improvement in life expectancy, a net gain in health and a reduction in total lifetime costs.
