4. Sweetened Beverages

Did you trade in your favorite soda for the supposedly healthier diet version? Sure, it has fewer calories, but according to a recent Illinois study of more than 260,000 Americans, it could come at a price. The study found people drinking at least four servings of either fruit punch, ice tea, or diet sodas suffered from a greater risk of a future diagnosis of depression. Do yourself, and specifically your future mental health, a favor and ditch sweetened beverages altogether. Drink water. And, if you need a flavor shot, try adding lemon, orange, or lime juice.
