Medscape reported this finding, which impacts pregnant women since they are often susceptible to depression during and after pregnancy. Once more we find reasons to eat well.

November 10, 2009 — Patients who consume a diet rich in high-fat dairy products and fried, refined, and sugary foods are at increased risk of developing depression, whereas those whose diet is rich in fish, fruit, and vegetables are at lower risk of developing depression, a new study shows.

Although other research has looked at the relationship between single nutrients and depression, this is the first study to investigate the effect of dietary patterns on depression.

The results suggest that diet should be considered a potential target for the prevention of depressive disorders, said the study's lead author, Tasnime N. Akbaraly, PhD, who completed the study while at the Department of Epidemiology and Public Health, University College, London, United Kingdom.

"The study can be an argument to help convince patients who have unhealthy eating behaviors that consuming a healthy diet not only controls excess weight but also may lower the risk of depression," Dr. Akbaraly added.

The study was published in the November issue of the British Journal of Psychiatry.

Conclusion:

• A whole food diet consists of large amounts of vegetables, fruits, and fish, whereas a processed food diet consists of high-fat dairy, sweet desserts, processed meats, and refined grains.
• Consumption of a whole food diet is associated with a reduced risk for depression, whereas consumption of a processed food diet is associated with an increased risk.
