Drinking diet soda and depression are linked to each other; this is according to a new study. Interestingly, the study suggested that drinking coffee has a slightly lower risk. The research, which involves 263,925 adults with ages 50 and 71 at the time of the study, was conducted from 1995 to 1996.

As noted in the abstract of the study posted at the official website of the American Academy of Neurology (AAN) on Tuesday, January 8, 2013, the participants that time consumed various drinks such as soda, tea, fruit punch, and coffee. Results revealed that those who consumed soda have a higher risk of having a depression.

Based on the AAN data, the participants who consumed more than four cans or cups per day of diet soda have a 30% increase in risk to suffer from depression, as compared to those who did not drink soda. Meanwhile, those who drank regular soda had a 22% risk increase of having depression.

Those who drank diet fruit punches had a risk increase of around 51% than those who did not, while those who consumed sugar-sweetened fruit punch had only 8 percent. Those who consumed four or more cans or cups of fruit punch had a 38% increase risk, as compare to soda.

But on the contrary, those who consumed four cups of coffee per day were around 10% less likely to develop depression than those who did not drink coffee. In addition, the data showed that consumption of diet iced tea also has a higher risk than drinking sugar-sweetened iced tea.

This latest study, which was released online that day and will be presented at the American Academy of Neurology‘s 65th Annual Meeting in San Diego, from March 16 to 23, 2013, was led by Honglei Chen, MD, PhD, with the National Institutes of Health in Research Triangle Park in North Carolina.

“Sweetened beverages, coffee, and tea are commonly consumed worldwide and have important physical—and may have important mental—health consequences.” Chen was quoted at, with the study supported by the National Institutes of Health, the National Institute of Environmental Health Sciences, and the National Cancer Institute.

“Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk. More research is needed to confirm these findings, and people with depression should continue to take depression medications prescribed by their doctors.” Chen added.
