High fish consumption may help reduce the risk of
depression, according to a survey conducted in China.
People who
are divorced or live separately are more likely to experience symptoms of mild
to moderate mental illness, with 27% showing signs of the disease compared to
20% of those who are single, cohabiting or widowed.
However, a fish- rich diet could be a solution
for the fight against these symptoms.
Researchers
from Qingdao Medical University, Shandong, China gathered data from studies
between 2001 and 2014 so as to evaluate the strength of evidence on the connection between fish intake and
depression.
The result
showed that those with the highest
intake of fish were associated with 17% lower risk of depression. The reduced risk in men was 20%, compared
to 16% in women. These were concluded from both cohort and cross- sectional
studies, but only for studies conducted in Europe.
An abundant
source of omega- 3 fatty acids found
chiefly in fish can change the generation of dopamine and serotonin, two brain
chemicals which are thought to link to depression.
Moreover, high quality protein, vitamins and minerals in fish play an important
role in the strategy of depression
prevention.
“Higher fish consumption may be
beneficial in primary prevention of
depression. However, there should be many further studies to investigate
whether this association is tailored to the type of fish,” added Professor
Zhang Dongfeng, lead researcher from the Department of Epidemiology and Health
Statistics, Qingdao Medical University, Shandong, China.
