Do Soft Drinks Lead to Depression?

Coca-Cola-Open-Happiness or DepressionA groundbreaking study, published this week by the American Academy of Neurology, has described a correlation between consumption of soft drinks (regular and diet) and depression. A decade long research project that included 263,000 participants aged 50 and older found that those who consumed 4 or more soft drinks per day were 30% more likely to develop depression than those who did not drink soda at all.

The same figures were observed for people who drank diet soft drinks. 4 cups of fruit punch – a 38% increase. Conversely, people who drank 4 cups of unsweetened coffee per day were 10% less likely to develop depression.

Now remember, correlation is not causation. So maybe the people who had a propensity for depression found solace in soft drinks. After all, one famous brand’s tagline is “Open Happiness”.

From our limited family experience, in the few instances our children are allowed to drink a soda pop, there is only joy to be seen. But we’re at 4 cups a quarter, not day.
