Researchers from Medical College of Qingdao University in China are suggesting people to eat fish-rich diet as it will make them less depressed.
The suggestion is based on one of the earlier studies that found the fish in diet helps in reducing depression by 17 percent compared to those who eat very less fish.
Details of the study can be found in the online edition of Journal of Epidemiology & Community Health.
Meanwhile, the data of World Health Organizations (WHO) reveals about 350 million people across the world suffer from depression and by 2020 it may become the second leading cause of ill health.
Researchers analyzed data of more than 1,50,000 people between the years 2001 and 2014 of 26 global studies to known how much the fish is related to depression.
It was found the risk in men lowered by 20 percent and among women it was 16 percent. It is said the omega-three fatty acids found in fish works in reducing the risk. It alters the activity of serotonin and dopamine.
Serotonin and dopamine chemicals send signals to the brain and these two are involved in depression.
It is also added the vitamins, minerals and protein found in fish helps in reducing the depression too.
Lead author of the study, Professor Dongfeng Zhang, said eating more may benefit in the primary prevention of depression.
Zhang is a professor of the Department of Epidemiology and Health Statistics, Medical College of Qingdao University, Shandong, china.
One other study earlier suggested eating ample amount of fish on regular basis improves eye sights too.
