A new study out of Sydney, Australia has shown a link between depression (and bipolar disorder) and deficiency of Omega-3 fatty acids in the diet. The researchers point out the practical applications of their work:

Lead researcher and institute director Professor Gordon Parker said his work found that omega-3 fish oil supplements could be used effectively alongside anti-depressants for people suffering depression.

Furthermore, their research had important things to say regarding pregnant mothers:

The study also found that mothers who had lower levels of omega-3 in their breast milk were more likely to suffer from postnatal depression.

This isn’t the first time that research has identified fish oil as a remedy for postpartum depression.
