BEIJING, Jan. 27 (Xinhuanet) -- Eating foods full of trans-fats and saturated fats may increase the risk of suffering from depression up to 48 percent, according to a new study.
By contrast, consuming olive oil and other products high in omega-9 fatty acids help prevent this illness, said the report published in the online journal PLoS ONE Thursday.
Researchers followed and analyzed the diet and lifestyle of over 12,000 volunteers over six years in Spain.
At the beginning of the study, none of the volunteers had depression, and by the end, 657 new cases had been diagnosed.
Of all these cases, the participants with an elevated consumption of trans-fats presented up to a 48 percent increase in the risk of depression compared to participants who did not consume these fats.
“Our findings suggest that trans-fat intake, a well known risk factor for cardiovascular disease, might also have a detrimental effect on depression,” wrote the study led by Almudena Sanchez-Villegas, a researcher at the University of Las Palmas de Gran Canaria in Spain.
Previous researches have already linked trans-fats, which are created through a process that adds hydrogen to oil, to increased heart risk.
