Past studies have strongly linked fast food to weight gain, obesity, and type 2 diabetes, and based on this evaluation it seems we may also need to add depression to this list.
In a long-term study that involved over 8,500 study subjects, those who consumed the most fast food (hamburgers, hot dogs, and pizza) were 51% more likely to develop depression vs. those who rarely or never ate fast food. And there was a direct dose-response relationship: the more fast food the higher the risk, which adds to the likelihood that this could be a direct cause and effect relationship.
As further motivation to keep fast food out of your and your loved ones’ lives- bear in mind that this exceedingly high-risk fare houses virtually every single feature scientists have identified that in one way or another leads to overeating. I NEVER eat traditional fast food! (Public Health Nutrition 15:3, 2012)
