Depression Risk may be Significantly Reduced with Fish-Rich Diet - November 2015
Eating fish may protect against depression, a new meta-analysis suggests. Taking Fish oil supplements shown to be ineffective.
"Fish is rich in multiple beneficial nutrients, including n-3 polyunsaturated fatty acids, high-quality protein, vitamins, and minerals. Furthermore, fish have been hypothesized to protect against chronic diseases generally, such as cardiovascular disease and cancer. Therefore, we suggest people should eat more fish," first author Fang Li, from, Medical College of Qingdao University, in China.
"The thing I am intrigued about is that there exists such strong evidence for an association between fish intake and depression, but when we try to supplement depressed patients in randomized, placebo-controlled trials with omega-3 fatty acids (the nutrients in fish thought to be responsible for the association), we find little or no evidence for an effect," Roel J. T. Mocking added.
"Moreover, if any effect, it seems to be a complex interaction between several nutrients in fish, or may point to some residual confounding for which the observational evidence cannot yet account," Mocking said.
The study was published online September 10 in the Journal of Epidemiology and Community Health.
