7Healthcast: Diet drink consequences

Posted: Updated:
UNDATED (WHDH) -

For many Americans diet drinks are a daily staple, but a new study says older women who drink more diet drinks may have a higher risk of deadly heart disease.

“Women who consumed two or more diet drinks had higher rates of cardiovascular events,” Dr. Ankur Vyas said.

The Women's Health Initiative study looked at 60 thousand post-menopausal women over a nine-year span.

The women who consumed two or more diet drinks per day were 30 percent more likely to experience a cardiovascular event, and 50 percent more likely to die from related heart disease than women who never or rarely drank diet drinks.

“A higher proportion of women with a history of diabetes, a higher proportion of women with history of high blood pressure…They also on average consumed higher calories than the women in the reference group,” Dr. Vyas said.

In a statement, the American Beverage Association said because of other factors, "It is impossible to attribute their cardiovascular health issues to their diet beverage intake.”

But for researchers looking into the science of heart disease it is at least cracking the surface.

“It raises a challenge to scientific community to look at this further and hopefully in the near future well have a definitive answer to this question,” Dr. Vyas said.

A question that has many wondering whether their favorite drink could have bitter consequences.
