Fight depression with healthy diet

We all know that stress makes us fat.

I wrote before about how you can fight depression with exercise and right nutrition. Now scientists confirm that.
Diet and nutrition may play a key role in helping people fight depression, Australian researchers report.
A number of nutrients, including polyunsaturated fatty acids 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.

Another candidate for dietary prevention of depression is the amino acid tryptophan, which is found in foods, including turkey, and is responsible for the drowsiness people feel after eating a hearty Thanksgiving dinner.

The body converts tryptophan to the neurotransmitter serotonin, suggesting the amino acid may have modest effects on mood.

There is a wealth of evidence suggesting that fish and the oils they contain - in particular omega-3 polyunsaturated fatty acid - are protective against depression, Volker and Ng write
