(HealthDay News) — Consuming more fish may reduce risk of depression, according to a report published online September 10 in the Journal of Epidemiology & Community Health.
Fang Li, of the department of epidemiology and health statistics at the Medical College of Qingdao University in China, and colleagues reviewed 26 studies published between 2001–2014. The studies included 150,278 people. Ten of the studies were done in Europe.
Participants who consumed the most fish had an associated risk reduction for depression of 17%, compared to those who ate the least. A slightly stronger association between high fish consumption and lowered depression risk was seen in men (20% risk reduction). Among women, reduction in risk was 16%. The association was only statistically significant for studies done in Europe, the researchers said. They didn’t find the same benefit when they looked at studies done in North America, Asia, Australia, or South America.
“Studies we reviewed indicated that high fish consumption can reduce the incidence of depression, which may indicate a potential causal relationship between fish consumption and depression,” Li told HealthDay.
