??Just under half of Americans reported drinking a minumum of one glass of soda every day, while two thirds said they drink at least one cup of coffee in accordance with a 2012 Gallup poll. Despite popular opinion about pop and weight gain, exactly the same survey found that regular pop drinkers do not weigh a lot more than non-soda drinkers.

But health experts say that even one glass of pop a day is too much, as it’s been associated with a variety of health issues, including a comparatively new one, clinical depression.

Preliminary data from a National Institutes of Health report that’ll be released at the American Academy of Neurology’s 65th Annual Meeting in March in San Diego show that regular soda drinkers, particularly those that drink diet soda, are more inclined to be identified as having depression. The data revealed that coffee drinkers, on the flip side, have a somewhat lower danger of a depression identification.

The researchers do not say that pop causes depression — they did not determine whether people who are prone to become depressed are also just more likely to drink soda in the very first place, and the study didn’t control for all relevant variables, including socioeconomic status. What they did find was that people who drank cups or more than four cans of soda per day were 30 percent more prone to develop depression over the span of the 10-year study than people who drank no pop. Fruit punch drinkers were 38 percent more likely to develop depression than those who didn’t drink sweetened beverages. Depression threat seemed to be even greater for individuals who drank diet, and diet soda instead of regular soda instead of regular fruit punches and iced tea.

Meanwhile, heavy coffee drinkers in the analysis experienced more than the usual caffeine buzz: They were about 10 percent less likely to develop depression than those who drank no java.

This recent finding doesn’t automatically mean you run out for a cup of joe and should cease Diet Coke cold turkey. But it is not the very first time researchers have found a link between mood and soda consumption. One study of teens in Boston found that those who drank more or six cans of soda per week were more apt to be violent with friends and family and even carry weapons. Researchers implied that sugar or caffeine might be to attribute, and associated substantial soda eating using a 9 percent to 15 percent rise in the danger of aggressive behavior.

Because previous studies have linked poor emotional health to the sugar in soda, this most recent finding is a bit more equivocal. It either indicates that both sugar and the artificial sweeteners in diet beverages might be associated with depression, or that other factors give rise to the link between pop drinking and clinical depression. However, cutting down on both diet and regular soda can help your quality of life in several means.

“Our research indicates that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk,” said study author Honglei Chen, MD, PhD, in a release. “More research is required to support these findings, and individuals with depression should continue to take melancholy medications prescribed by their doctors.”
