Could your diet be giving you the blues? If you are eating fast food on a regular basic you might want to take a moment to consider how cheap and easy it really is. Once you factor in the changes it can make to your physical and mental well being, the true price of that cheap stuff gets steep real fast. According to a 2012 study in the journal Public Health Nutrition, people who eat fast food are 51 percent more likely to develop depression than those who don’t. To clarify: When we say fast food, we’re talking about hamburgers, hot dogs, pizza, and commercial baked goods. Eating a small portion of any one food is unlikely to raise depression risk, but if you see Ronald, Wendy, The Colonel or Popeye on a regular basis, a drastic dietary adjustment would be a great step toward happier feelings and less depression.
