Fish is rich in many beneficial nutrients, including Ω-3 polyunsaturated fatty acids, high quality protein, vitamins and minerals, and after a new meta-analysis, of the Department of Epidemiology and Health Statistics, in the Medical College of the ‘University Qingdao, in China, it is suggested that eating fish may protect against depression.

The analysis included 26 studies involving 150.278 participants. Ten studies were conducted in Europe, seven in North America, four in Asia, three in Oceania, and two in South America.

All studies were carefully examined independently by two investigators to identify and determine if an individual study was eligible for inclusion criteria for this meta-analysis.

This meta-analysis provides a valuable and timely contribution to this emerging field. Previous reviews focused in particular on the consumption of omega 3 fatty acids, but there were limitations to study individual nutrients; in this way, looking at the consumption of fish, the study is noteworthy.

A meta-analysis on the relationship between eating habits and incidence of depression, reported recently in the American Journal of Clinical Nutrition, suggested that a high intake of fruits, vegetables, fish and whole grains may be associated with a reduced risk of depression.

The fact that the consumption of fish reduces the risk of depression is supported by current evidence with regard to the use of diet, omega-3, and fish.

The thing that intrigued is that there is strong evidence of an association between fish intake and depression.
