A new study shows that junk food may have effects beyond expanding your waistline and upping your sodium levels -- it might also be sabotaging your mental health.

A new study in the journal Public Health Nutrition shows that regularly eating commercial baked goods -- including doughnuts and croissants -- as well as fast food -- pizza, hamburgers and hot dogs -- is linked with an increased depression risk.

Researchers from the University of Las Palmas de Gran Canaria and the University of Granada found that the people who regularly eat these foods are also more likely to be more sedentary, smoke, eat other not-so-nutritious foods and work 45 or more hours a week.
