A recent study published in Molecular Psychiatry investigated the association between the South European Atlantic Diet (SEAD) and the risk of depression. SEAD is a traditional diet consumed in northern Portugal and northwestern Spain, characterized by high consumption of dairy, legumes, meat, pork products, fish (especially cod), and vegetables.
Research Details: The study analyzed data from five cohort studies, including participants from Spain, Poland, and the United Kingdom. Adherence to SEAD was assessed using a point method based on nine food groups. Depression was measured using various scales and criteria.
The findings revealed that individuals who adhered more closely to SEAD had a reduced risk of depression. This association remained consistent across different cohorts and countries. Consumption of fresh fish, cod, pork products, red meat, vegetables, legumes, potatoes, vegetable soup, whole grain bread, and small amounts of wine were specifically associated with a lower risk of depression.
Mental Health Benefits of SEAD: The study highlighted the potential mental health benefits of SEAD, in addition to the known advantages for gastrointestinal and cardiovascular health. The higher levels of zinc, omega-3 fatty acids, and magnesium found in SEAD foods may contribute to the observed positive association with depression risk reduction.
While previous research has demonstrated the positive impact of SEAD on various health outcomes, its influence on mental health disorders had not been extensively studied until now. These findings provide valuable insights into the potential role of SEAD in promoting mental well-being.
Study Limitations: It is important to note that the study had limitations, including the use of self-reported dietary data and the heterogeneity of the cohorts. Future research should further explore the mechanisms underlying the relationship between SEAD and mental health and consider other factors that may influence depression risk.
Conclusion: Overall, the study contributes to our understanding of the association between dietary patterns and mental health, emphasizing the potential benefits of SEAD in reducing the risk of depression. Further investigation in this area could provide valuable insights for the development of dietary interventions to support mental well-being.
