A study, which followed almost 2,600 older adults for a decade, found that those who drank diet soda every day were 44% more likely than non-drinkers to suffer a heart attack or stroke. Daily diet-soda drinkers did tend to be heavier and more often have heart risk factors like high blood pressure, diabetes and unhealthy cholesterol levels. But even after the researchers factored in those differences along with people's reported diet and exercise habits they found that daily diet soda was linked to a 44% higher chance of heart attack or stroke.
