Fish oils, vitamins, herbs helpful for depression

Diet and nutrition may play a key role in helping people fight depression, Australian researchers report.

A number of nutrients, including polyunsaturated fatty acids, St. John's Wort and several B vitamins, have the potential to influence mood by increasing the absorption of chemical messengers in the brain, Dr. Dianne Volker of the University of Sydney in Chippendale and Jade Ng of Goodman Fielder Commercian in North Ryde, New South Wales note in the journal Nutrition and Dietetics.

There is a wealth of epidemiological, experimental and circumstantial evidence to suggest that fish and the oils they contain, in particular omega-3 polyunsaturated fatty acid, are protective against depression, Volker and Ng write. They point out that the balance between omega-3 and omega-6 may also be important, given that the latter can prevent the body from absorbing the former.
