Objective: The results from observation studies on the relationship between coffee intake and risk of depression and the relationship between caffeine consumption and depression remain controversial. We conducted a meta-analysis with a dose–response analysis to quantitatively summarize the evidence about the association between coffee and caffeine intakes and risk of depression. Method: Relevant articles were identified by researching PubMed, Web of Science, China National Knowledge…

This study suggests that black tea consumption up to 4 cups and caffeine intake between 450–600 mg can help protect against depression.

Coffee consumption and health: umbrella review of meta-analyses of multiple health outcomes

Coffee consumption seems generally safe within usual levels of intake, with summary estimates indicating largest risk reduction for various health outcomes at three to four cups a day, and more likely to benefit health than harm.



Tea consumption and the risk of depression: A meta-analysis of observational studies

A meta-analysis of findings from observational studies found a linear association between tea consumption and the risk of depression, with an increment of 3 cups/day in tea consumption associated with a decrease in therisk of depression.

Findings from this meta-analysis indicate that moderate coffee consumption may be weakly inversely associated with risk of stroke.

It is found that depression risk decreases with increasing caffeinated coffee consumption, and decaffeinated coffee was not associated with depression risk.

Findings support a possible protective effect of coffee on the risk of depression in the Korean population and observe a similar association for self-reported clinical depression.

Significant evidence from well-designed observational studies is required to confirm or refute the association between dietary intake and depressive symptoms in free-living settings.

The association between caffeine and cognitive decline: examining alternative causal hypotheses

No evidence is found that reduced risk of cognitive decline in women with high caffeine consumption is moderated or confounded by diabetes or depression, and further research should focus on the high estrogen content of coffee as a plausible alternative explanation.
