Eating Fish Reduces Depression

September 15, 2015 - 08:34

A high fish diet lowers the risk of becoming depressed by around 17 per cent, studies show. For men it is even higher, cutting the likelihood by 20 per cent.  Read more about this recent research by clicking on the title or photo...

Beyondblue figures show around 1 million Australian adults have depression in any year. One in seven will experience depression in their lifetime.

However, consuming a diet that is high in fish could be an easy way of preventing symptoms.

Studies involving more than 150,000 people have suggested the omega 3 fatty acids in fish may alter the production of the brain chemicals dopamine and serotonin, both of which are thought to be involved in depression.

“Higher fish consumption may be beneficial in the primary prevention of depression,” said lead author Professor Dongfeng Zhang, of the Department of Epidemiology and Health Statistics, Qingdao University in China.

“Future studies are needed to further investigate whether this association varies according to the type of fish.”

Researchers pooled data from studies published between 2001 and 2014 to assess the strength of the evidence on the link between fish consumption and depression risk. A significant association emerged between those eating the most fish and a 17 per cent reduction in depression risk compared with those eating the least.

When they looked specifically at gender, researchers found a slightly stronger association between eating a lot of fish and lower depression risk in men. Among women, the associated reduction in risk was 16 per cent.

The authors think the high-quality protein, vitamins and minerals 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 research was published in the Journal of Epidemiology & Community Health.
