Researchers confirm link between fast food, depression

Spanish researchers have concluded that there is a definite link between fast food and depression. A new study reveals that consumers of fast food are 51 percent more likely to develop depression than those who eat little or none. “The more fast food you consume, the greater the risk of depression,” Almudena Sánchez-Villegas, lead author of the study, said. “Even eating small quantities is linked to a significantly higher chance of developing depression.” The study looked at 8,964 participants that had never been diagnosed with depression or taken antidepressants. They were assessed for an average of six months, and 493 were diagnosed with depression or started to take antidepressants. Still, little is known about the role that diet plays in developing depression. Previous studies suggest that certain nutrients, including B vitamins, omega-3 fatty acids and olive oil, play a preventative role.
