"We found that these healthy fats, along with olive oil, are associated with a reduced risk of depression," says Miguel Angel Martínez-González

The intake of trans fats and saturated fats increases the risk of depression. However, daily consumption of olive oil protects against the disease. The conclusion is a study from the University of Navarra and Las Palmas de Gran Canaria, Spain.

The discovery was made from the analysis of lifestyle, diet and diseases of over 12 000 volunteers SUN - Monitoring Project at the University of Navarra.

Among the volunteers were diagnosed 657 new cases of depression. The researchers noted that among participants with high intake of trans fatty acids found in fast foods, showed an increased risk of depression (48%) when compared with participants who consumed little fat, revealed Almudena Sánchez-Villegas, professor of Preventive Medicine, University Las Palmas de Gran Canaria, the main author.

Another team, led by Miguel Angel Martínez-González, professor of Preventive Medicine of the Navarra University, examined the influence of polyunsaturated fat, abundant in fish and vegetable oils and olive oil in the presence of disease: "In fact, we found that these healthy fats, along with olive oil, are associated with a reduced risk of depression, "he said.

The study results support the view of the increase in disease incidence in northern European countries compared to southern countries where the prevailing dietary pattern is the Mediterranean. Experts warn that in recent years the incidence of disease has increased, reaching 150 million people worldwide.

According to Villegas Almudena Sánchez, "a radical change in the sources of fats consumed in Western diets, where we have replaced some kinds of beneficial fats, polyunsaturated and monounsaturated fats - found in nuts, vegetable oils and olive oil and fish - for saturated and trans - found in meat, butter and fast food. "

The analysis, conducted by the University of Navarra and Las Palmas de Gran Canaria, suggests that depression and cardiovascular disease are also influenced by diet and share a similar mechanism at the origin. This is supported by numerous studies showing the harmful effects of saturated and trans fats on cardiovascular risk.
