Abstract
Although some studies have reported potential associations of dietary patterns with depression risk, a consistent perspective hasn't been estimated to date. Therefore, we conducted this meta-analysis to evaluate the relation between dietary patterns and the risk of depression. A literature research was conducted searching MEDLINE and EMBASE databases up to September 2016. In total, 21 studies from ten countries met the inclusion criteria and were included in the present meta-analysis. A dietary pattern characterized by a high intakes of fruit, vegetables, whole grain, fish, olive oil, low-fat dairy and antioxidants and low intakes of animal foods was apparently associated with a decreased risk of depression. A dietary pattern characterized by a high consumption of red and/or processed meat, refined grains, sweets, high-fat dairy products, butter, potatoes and high-fat gravy, and low intakes of fruits and vegetables is associated with an increased risk of depression. The results of this meta-analysis suggest that healthy pattern may decrease the risk of depression, whereas western-style may increase the risk of depression. However, more randomized controlled trails and cohort studies are urgently required to confirm this findings.

Healthy dietary indices and risk of depressive outcomes: a systematic review and meta-analysis of observational studies

TL;DR: To conclude, adhering to a healthy diet, in particular a traditional Mediterranean diet, or avoiding a pro-inflammatory diet appears to confer some protection against depression in observational studies, which provides a reasonable evidence base to assess the role of dietary interventions to prevent depression.

Diet quality and depression risk: A systematic review and dose-response meta-analysis of prospective studies.

TL;DR: There is evidence that a higher quality of a diet is associated with a lower risk for the onset of depressive symptoms, but not all available results are consistent with the hypothesis that diet influences depression risk.

Measuring inconsistency in meta-analyses

TL;DR: A new quantity is developed, I 2, which the authors believe gives a better measure of the consistency between trials in a meta-analysis, which is susceptible to the number of trials included in the meta- analysis.

Operating characteristics of a rank correlation test for publication bias.

TL;DR: In this paper, an adjusted rank correlation test is proposed as a technique for identifying publication bias in a meta-analysis, and its operating characteristics are evaluated via simulations, and the test statistic is a direct statistical analogue of the popular funnel-graph.

Critical evaluation of the Newcastle-Ottawa scale for the assessment of the quality of nonrandomized studies in meta-analyses

TL;DR: The quality assessment of non-randomized studies is an important component of a thorough meta-analysis of non randomized studies and can dramatically influence the interpretation of meta-analyses, and can even reverse conclusions regarding the effectiveness of an intervention.

Fish consumption and major depression

TL;DR: The hypothesis that a high consumption of fish could be correlated with a lower annual prevalence of major depression was tested and the direction and power of the correlation between apparent fish consumption and major depression did not show that fish consumption can cause differences in the prevalence ofmajor depression or that eating fish or fish oils are useful in treatment.
