Millions of people reach for an afternoon diet soda as a pick-me-up to make it through the rest of the day. But new research suggests sodas and other sugary drinks — especially artificially sweetened ones — could be related to depression.
According to the research, which will be officially released at the American Academy of Neurology’s annual meeting in mid-March, people who drink four cans or more of soda daily are about 30 percent more likely to be diagnosed with depression than people who don’t drink soda. Coffee drinkers are about 10 percent less likely to develop depression than people who don’t drink coffee.
The National Institutes of Health study included more than 250,000 people between the ages of 50 and 71 and studied their drink consumption during 1995 and 1996. A decade later, researchers asked whether participants had been diagnosed with depression since the year 2000.
According to researchers, “the risk appeared to be greater for people who drank diet [rather] than regular soda.”
