Study: Mediterranean Diet Promotes Mental Health

A recent study has concluded that following the Mediterranean diet can have a positive effect on mental health. Researchers from University College London (UCL) analyzed 41 observational studies that linked people’s dietary choices to depression. After reviewing the studies, analysts found compelling evidence that people who are on the Mediterranean diet were 33% less likely to develop depression. The Mediterranean diet consists mainly of vegetables, fruits, nuts, fish, and healthy fats from olive and canola oils. According to experts, these healthy foods contain nutrients that help control the levels of brain chemicals, thus improving one’s mood and brain function. In addition, a previous research had also shown that consumption of healthy fats such as omega-3 found in fatty fish aids in managing the symptoms of mental health disorders, including stress, anxiety, and mood disorders. On another note, UCL researchers also found that people who prefer food rich in sugar and unhealthy fat are more susceptible to depression. Studies show that sugary and fatty foods can cause an imbalance in brain chemicals, which is often correlated with depression. Despite the conclusion of this large-scale analysis, researchers believe that further testing is necessary. Dr. Camille Lassale, one of the analysts, recommended clinical trials to solidify the connection between a healthy diet and better mental health. In support of the analysts’ recommendation, a professor from the University of Glasgow suggested that a random trial be conducted on people who are at risk of depression. The professor said it would require a huge effort on the part of the researchers, but the results would be very valuable.
