The food can influence mood. A diet low in omega-3 fats, it can make it prone to anxiety and depression. This was revealed by a study on mice published in the journal Nature Neuroscience by Sophie Laye and Olivier Manzoni Institute of Neurobiology Inserm Institute of Neurobiology in Marseille.
While another study, which involved 12,000 volunteers, mean age 37 years, published in the journal PLoS One, shows that a diet too rich in trans fats and saturated fats is associated with a risk of developing depression by 48% higher than normal. That food can influence mood and other psychological traits and cognitive function, is now the subject of interest of several research groups around the world.
These two works show that the fat, well-known cardiovascular risk factor, may have a bearing on the health of the psyche. Manzoni's group studied mice born to mothers fed a diet low in omega-3 (good fats found in fish) and weaned onto the same diet. These mice have behaviors indicative of anxiety and depression. The mice also had reduced neural plasticity in the prefrontal cortex and the level of the nucleus accumbens, two areas related to mood disorders.
The other study, however, directed by Almudena Sanchez-Villegas, University of Las Palmas (Gran Canaria), shows similar results on people whose health was monitored for an extended period of time. Scientists in Spain have found a close correlation between the type of each diet and the risk of depression. The higher consumption of saturated and trans fats, the greater the risk of depression. Conversely, the higher the consumption of olive oil and polyunsaturated fats, lower this risk.
