According to a new survey conducted in the United Kingdom, people who eat lots of fish are considerably at lower risk of suffering depression in their lives.
Depression has now become more of a lifestyle disease affecting almost half the population on earth. The condition is usually treated with a bout of anti depressant drugs, psycho therapy or both. The outcomes of these treatments have not been known to fetch long term results. Alternative therapy is widely sought worldwide in the form of Yoga, meditation and Reiki.
Studies have suggested that a healthy diet plays a vital role in reducing the risk of developing depression. A recent analysis of studies indicates that diet containing lots of fruit, vegetables, fish and whole grains is associated with a reduced risk of depression.
Other studies have also looked specifically at fish and the role it plays in reducing the risk of depression, but the results of these studies have been contradictory or inconclusive.
Pooled Stats From The Recent Study
In the most recent study, researchers at Qingdao University in China collated data from 26 observational studies to establish a clearer picture of the association between fish consumption and depression.
The combined studies comprised of data on 150,278 people from Europe, Asia, North America, South America and Oceania. However, women with post partum depression were excluded from the studies. Interestingly, the post -partum depression forms a major factor that triggers clinical depression in women.
Out of 26 studies, 12 showed a significant association between eating lot of fish and a reduced risk of depression, while 14 found no such relationship. The combined data from all the studies showed that those who eat the most fish have a 17% lower risk of having depression compared with those who eat the least or no fish at all.
When the researchers went through data by continent, it was found that the fish-depression association only existed in the combined European studies. the reason was not discussed in the paper.
The researchers conclude that higher fish consumption may be beneficial in the primary prevention of depression.
