Does Drinking Soda Lead to Depression?

It looks like soda is taking another hit. We already know that sodas are packed with sugar and aren't healthy for our bodies. But now it sounds like the sugary drink isn't good for our mental health either. Participants who drank more than four servings of soda each day were 30 percent more likely to be diagnosed with depression than those who didn't drink soda at all.

The study, which will be presented at the American Academy of Neurology's yearly meeting in March, involved about 260,000 participants between the ages of 50 and 71. Researchers tracked their consumption of drinks like soda, tea, coffee, etc from 1995 to 1996 and then, a decade later, asked if they had been diagnosed with depression. Do you think soda leads to depression? Or is the study's findings just a coincidence?

We know that sugary sodas aren't good for our bodies; now it turns out that they may not be good for our minds, either. A new study has found a link between sweetened soft-drinks and depression -- and diet sodas may be making things worse.
