Omega-3 v depression.

Dr Kentaro Murakami examined the link between fish consumption and depression in 6,500 Japanese boys and girls aged 12 – 15.

Depressive symptoms were evaluated using a clinical scale, with 22.5% of boys and 31.2% of girls reaching the threshold level.

Diet was evaluated using a food frequency questionnaire.

The researchers looked at total fish intake, and the estimated amounts of 2 omega-3 fatty acids, EPA and DHA.

For the boys, both total fish intake and EPA intake were associated with a reduced risk of depression, while there was no significant link with DHA.

For the girls, there was no link between fish consumption, EPA or DHA, and depression. The researchers speculated this might be because there is a stronger genetic component to depression with girls, so diet plays a smaller role.
