This interesting free full-text journal article reviews the use of foods rich in omega-3 fats as a method of treating depression. It concludes that there is a good deal of epidemiological, laboratory and clinical evidence suggesting that omega-3s could play a role in the treatment and prevention of the illness.
While the report calls for further study, it encourages all mental health professionals to ensure that their patients suffering from depression have an adequate intake of omega-3 fats.
Currently, the average daily intake by Americans of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is about 130 mg, only a fifth of the minimum requirement recommended by international experts.
The report also argues that mental health specialists do not have to be experts in clinical nutrition to be aware of the real connection between nutritional habits and emotional health.
