Turning to diet fizzy drinks might be harming your health.
A new National Institute of Health study found that people who drink a lot of diet soda were more likely to be diagnosed with depression.
The findings showed that those who drank more than four cans or cups of any kind of fizzy pop were 30% more likely to develop depression than non-drinkers.
Interestingly, those that drank the diet varieties showed a stronger link to depression than the non-dieters.
The study followed 264,000 people between the ages of 50 and 71 and looked into their consumption of a variety of drinks including sodas, tea, fruit juice and coffee, and checked back over a ten year period to see who had been diagnosed with depression.
Drinking unsweetened coffee was found to be much better as people who sank four cups a day were ten per cent less likely to develop depression than non-coffee drinkers.
'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,' said study author Honglei Chen, MD, PhD.
'More research is needed to confirm these findings, and people with depression should continue to take depression medications prescribed by their doctors.'
Whilst the study is interesting, it is not conclusive that fizzy drinks can cause depression.
Lisa Young, nutritionist and professor of Nutrition, Food Studies and Public Health at NYU explained, 'I'm not a fan of diet soda, but I don't think it's the soda alone that's causing depression.'
Speaking to the Daily News she added, 'The thing about soda is, you don't often drink it alone - you drink it with junk food. You're not getting enough fibre and protein with that sugar, and your blood sugar not being stable could throw off your mood.'
