Mediterranean diet and mental distress: “10,001 Dalmatians” study

Purpose The impact of eating habits on mental health is gaining more attention recently. The purpose of this paper is to investigate the association between mental distress and the Mediterranean diet (MD) in a community-dwelling adult population of Dalmatia, Croatia. Design/methodology/approach Participants from the “10, 001 Dalmatians” study from the Island of Korcula and the City of Split were included (n=3, 392). Lifestyle habits were investigated using a self-administered questionnaire, while mental distress was evaluated using the General Health Questionnaire-30 (GHQ-30) in a cross-sectional design. MD compliance was assessed using the Mediterranean Diet Serving Score. Multivariate linear regression analysis was used in the analysis. Findings MD compliance was associated with lesser mental distress (ß=−1.96, 95% CI −2.75, −1.17 ; p<0.001). Inverse association was found between mental distress and higher intake of fruits (ß=−0.64 ; 95% CI −0.89, −0.39 ; p<0.001), vegetables (ß=−0.39 ; 95% CI −0.65, −0.13 ; p=0.003), olive oil (ß=−0.30 ; 95% CI −0.56, −0.04 ; p=0.022) and legumes (ß=−0.83 ; 95% CI −1.66, 0.00 ; p=0.049). Mental distress was more intense in women, older participants, those with worse material status, subjects with previously diagnosed chronic diseases and in current smokers. Originality/value This study suggests beneficial association of MD and overall mental health, offering important implications for public health provisions. Since the literature search did not reveal any previous study on the association between the MD and GHQ- based mental distress in the general population, this study delivers interesting results and fills this knowledge gap.
