Introduction: Nutritional patterns as one of the most important aspects of health have a great impact on physical and mental performance. The role of dietary patterns and consumption of different food groups on mental health in different populations is very important. Therefore, the present study was conducted with the aim of a systematic review of the role of nutritional patterns in mental health.
Methods: The present study was conducted by systematic review. Using the keywords (Health OR Mental Health) (diet OR nutrition OR food), (pattern OR habit OR behavior) in the databases Elsevier, Science Direct, Pubmed, Scopus, Googlescholar, SID and after removing duplicate and irrelevant articles, 20 full-text articles published between 2000 and 2020 were reviewed.
Results: Two types of healthy and unhealthy eating patterns were effective in mental health. Healthy eating patterns such as dairy, fruits, vegetables and meat (fish), omega 3, folate, B vitamins (B6 and B12, niacin), vitamins D, C, A, E, antioxidants, legumes, nuts , Grains and unsaturated fats such as olive oil are effective in increasing mental health. An unhealthy diet, such as consuming too much saturated fat and sugar, has a negative effect on mental health.
Conclusion: There is currently little evidence linking mental health and nutritional patterns. Therefore, it is difficult to Conclusion and definitive research in this regard. Also confounding factors such as age, sex, education level, severity of obesity, economic status, smoking, alcohol and social support are effective in predicting mental health. More detailed studies are needed to investigate the impact of these factors on mental health.
