Eating Fish Daily May Help Curb Depression

Eating a lot of fish may help curb risk of depression in both men and women, reveals a pooled analysis of the available evidence. After accumulating all the European data together, it was found that those who consumed fish on a regular basis were 17 percent less susceptible to depression as compared to others. The experts found a slightly stronger association between high fish consumption and lowered depression risk in men (20 percent). Among women, the associated reduction in depression risk was 16 percent.

"Higher fish consumption may be beneficial in the primary prevention of depression. Future studies are needed to further investigate whether this association varies according to the type of fish," the authors noted in a paper which appeared online in the Journal of Epidemiology & Community Health.

Several previous studies have looked at the possible role of dietary factors in modifying depression risk, but the findings have been inconsistent and inconclusive. The researchers pooled data from relevant studies published between 2001 and 2014 to assess the strength of the evidence on the link between fish consumption and depression risk. After trawling research databases, they found 101 suitable articles, of which 16 were eligible for inclusion in the analysis. These 16 articles included 26 studies, involving 150,278 participants.

"The high-quality protein, vitamins, and minerals found in fish may help stave off depression while eating a lot of fish may be an indicator of a healthy and more nutritious diet," the researchers suggested.(Are You Depressed Without Knowing It?)

Depression affects an estimated 350 million people worldwide, and is projected to become the second leading cause of ill health by 2020.
