It is generally accepted that socioeconomic status (SES) influences dietary habits as well as human health. Three main parameters have been most often used to define SES, i.e. occupation, education and income. These characteristics cover different aspects of the socioeconomic structure of people. The aim of this review is to present the current knowledge regarding the relationships between SES, dietary habits and health-related outcomes in various parts of the world.

Objective: The aim of the present work was to calculate the current cost of the Mediterranean diet in Greece and to evaluate the role of diet cost in the development of cardiovascular events after a 5-year follow-up. Design: Cross-sectional. Cost of diet was measured in h/week based on common Greek dietary choices, while baseline dietary habits were assessed through a semiquantitative FFQ (Greek-EPIC). The Mediterranean Diet Score (MedDietScore) was applied to assess overall adherence to this pattern using scores of eleven food variables and alcohol, according to the principles of the Mediterranean diet. Setting: Five-year follow-up of the ATTICA study, a nutrition and health survey of a representative, free-living sample of the Greek population resident in the province of Attica, where Athens is a major metropolis.
