Assessment of the impact of Mediterranean diet and other lifestyle factors on well-being.

Well-being is a broad concept that integrates objective social and environmental factors, as well as psychological factors. Some studies have suggested that diet may influence psychological well-being. However, no relationship between Mediterranean Diet and psychological well-being were found so far, rendering it difficult to reach a firm conclusion. Furthermore, these associations may be influenced by other behaviours that also impact on well-being, such as physical activity, sociality, and sleep quantity. Thus, this study is focused on a multifactorial approach to well-being by studying the association between lifestyle factors and subjective factors of well-being
