A new research study, led by Chen and colleagues from the National Institutes of Health (NIH), finds that people who drink more than four cans or cups per day of soda, diet or regular soft drinks, are 30 percent more likely to develop depression than those who do not drink soda. The same study finds that people who drink four cans or more of fruit punch per day have a 38 percent increased risk of developing depression.
Past studies have also linked soft drink or soda consumption to an increased risk of stroke and heart disease. In one study, women who drank sugary soft drinks almost every day were found to be 83 percent more likely to have a specific type of stroke than women who did not drink sodas or other sweetened beverages.
In addition, the NIH-funded Northern Manhattan Study found that those who drink diet sodas on a regular basis have a 43 percent increased risk of a stroke or heart disease than those who rarely drink soda. The sodium content in both diet and regular soft drinks are believed to be the factor that causes this increased risk in heart disease and stroke. More information is available in the above video.
