Daily Diet Sodas Linked to Heart Attacks, Strokes

Gulping diet sodas might not be such a good idea even if they are a lot less caloric than sugary soft drinks. New research links an increased risk of heart attacks, strokes and other vascular problems to drinking diet soda.

The study of 2,564 New Yorkers found that people who guzzle the beverages every day have a 61 percent higher risk of cardiovascular events than those who don’t drink diet sodas, even after filtering out the impact of smoking, physical activity, alcohol consumption and calories consumed per day.

“If our results are confirmed with future studies, then it would suggest that diet soda may not be the optimal substitute for sugar-sweetened beverages for protection” against cardiovascular problems, Hannah Gardener, lead author of the study and an epidemiologist at the University of Miami, said in a news release.

Gardener stressed that more studies need to be conducted. “I think diet soda drinkers need to stay tuned,” she told MSNBC. “I don’t think that anyone should be changing their behaviors based on one study.”

Some other researchers faulted the study. “One of the many flaws here is that participants were asked about soda intake at only one point in time, when they entered the study,” said Dr. Richard Besser, chief health and medical editor for ABC News. “It is difficult to imagine that people’s intake of soda is constant during that period.”

The study found no increased risk among people who drank regular soda. Dr. Howard Weintraub, clinical director of the New York University Center for the Prevention of Cardiovascular Disease, said this may reflect the tendency of people with poor dietary habits to wash down a high-fat meal with a low-calorie soda.

Drinking regular or diet soda has previously been linked to diabetes and metabolic syndrome, a precursor to diabetes. “Any way you slice it, soda drinking is not healthy and should be done sparingly,” said Dr. Peter McCullough, a cardiologist in Southfield, Mich. Neither McCullough nor Weintraub was involved in the study.

The people tracked in the analysis came from the Northern Manhattan Study, a project teaming researchers from the University of Miami and Columbia University. The project was launched in 1993 to examine stroke incidence and health risk factors in multiethnic urban populations.

    Aren’t overweight people who have a higher risk for heart problems more likely to drink diet soda?
