Abstract:
Given the role of dietary antioxidants in relieving depression, anxiety, and stress, as well as studies on the beneficial effects of the Mediterranean and Dash diets separately on these problems, in this study, we examine the relationship between the MIND index (Mediterranean- DASH diet Intervention for Neurodegenerative Delay) as a combined indicator of the Mediterranean and DASH diet with psychological disorders such as depression, anxiety, and psychological stress among a large sample of the Iranian adult population. Methods This cross-sectional study was performed on 7165 participants of the enrollment phase of Yazd Health Study (YaHS) and Yazd Nutrition Study (TAMYZ) a valid 178-item semi-quantitative food frequency questionnaire (FFQ) was used to assess participants’ food intake. The MIND diet score was calculated based on participants’ dietary intakes obtained from FFQ. Also, the valid Iranian version of the Depression, Anxiety, and Stress Scale (DASS 21) was used to assess psychological disorders and stress. In addition, the association between the MIND diet and psychological disorders and stress was assessed through logistic regression. Results The mean ± SD score was 3.33 ± 3.79 for depression, 2.99 ± 3.65 for anxiety, and 5.93 ± 4.70 for psychological stress. The mean score of MIND in this study was 7.56. After adjustment for after adjusting for age, gender, intake of energy, BMI, history of chronic disease, marital status, education level, smoking history, physical activity level, pregnancy or lactation, intakes of dietary EPA, DHA, and fiber, individuals in highest compared to the lowest quartile of MIND diet score had significantly lower odds of depression (OR = 0.62, 95% CI 0.40 – 0.96; P-trend = 0.02) and anxiety (OR = 0.61, 95% CI 0.41 – 0.91; P-trend = 0.01). However, no significant association was observed for psychological stress (OR = 0.57, 95% CI 0.28 – 1.14; P-trend = 0.83). Conclusion Therefore, it seems that following the MIND diet can prevent the possibility of these psychological problems. However, there is a need to design studies with more robust methodologies such as clinical trial studies.
