Individuals who follow the Mediterranean dietary pattern -rich in vegetables, fruits, nuts, whole grains and fish- appear less likely to develop depression, according to a report of the University of Navarra, published in the October issue of Archives of General Psychiatry.
The lifetime prevalence of mental disorders has been found to be lower in Mediterranean than Northern European countries, according to background information in the article. One plausible explanation is that the diet commonly followed in the region may be protective against depression. Previous research has suggested that the monounsaturated fatty acids in olive oil -used abundantly in the Mediterranean diet- may be associated with a lower risk of severe depressive symptoms.
The researchers studied 10,094 healthy Spanish participants who completed an initial questionnaire between 1999 and 2005. Participants reported their dietary intake on a food frequency questionnaire, and the researchers calculated their adherence to the Mediterranean diet based on nine components (high ratio of monounsaturated fatty acids to saturated fatty acids; moderate intake of alcohol and dairy products; low intake of meat; and high intake of legumes, fruit and nuts, cereals, vegetables and fish).
30% reduction in the risk of depression
After a median (midpoint) of 4.4 years of follow-up, 480 new cases of depression were identified, including 156 in men and 324 in women. Individuals who followed the Mediterranean diet most closely had a greater than 30 percent reduction in the risk of depression than those who had the lowest Mediterranean diet scores.
"The specific mechanisms by which a better adherence to the Mediterranean dietary pattern could help to prevent the occurrence of depression are not well known," the
