A cross-sectional online survey of 100 adults used validated questionnaires to assess Mediterranean diet adherence alongside anxiety and depression. Spearman's correlation analysis revealed that higher Mediterranean diet adherence was significantly associated with lower levels of both depression and anxiety.
This cross-sectional study surveyed 100 adults (61% women, 31% men; average age 37) recruited via online platforms in South Florida and globally. Participants completed three validated questionnaires: the 14-item Mediterranean Diet Adherence questionnaire, the Generalized Anxiety Disorder-7 (GAD-7), and Beck's Depression Inventory (BDI). The association was stronger for depression than anxiety. Limitations include the cross-sectional design precluding causal inference, self-reported data, a predominantly White and female sample, and potential unmeasured confounders such as physical activity and medication use.
