Researchers in Spain followed 8.964 subjects who had never been diagnosed with depression followed for over six years, finding that consumers of fast food were 51% more likely to develop depression. At the time of the study, 493 cases were reported. “The more fast food you consume, the greater the risk of depression,” says Almudena Sanchez-Villegas, the lead author of the study, “… Even eating small quantities is linked to a significantly higher chance of developing depression.” The effect was found, moreover, even when adjusted for consumption of other food items. Results appear in Public Health Nutrition.
