World-first trial shows improving diet can treat major depression - Medical News Today
In the study, adults with major depressive disorder were recruited and randomly assigned to receive either social support, which is known to be helpful for people with depression, or support from a clinical dietitian, over a three-month period. The dietary group received information and assistance to improve the quality of their current diets, with a focus on increasing the consumption of vegetables, fruits, wholegrains, legumes, fish, lean red meats, olive oil and nuts, while reducing their consumption of unhealthy 'extras' foods, such as sweets, refined cereals, fried food, fast-food, processed meats and sugary drinks. […] The results of the study, published in the international journal BMC Medicine, showed that participants in the dietary intervention group had a much greater reduction in their depressive symptoms over the three-month period, compared to those in the social support group. At the end of the trial, a third of those in the dietary support group met criteria for remission of major depression, compared to 8 percent of those in the social support group.
