Zero calories, same great taste (and heart risks)

Diet soda linked to same health problems as sugary drinks in bubbly puzzle

Sodas — even diet ones — may be linked with increased risk factors for heart disease and diabetes, researchers said on Monday.

They found adults who drink one or more sodas a day — diet or regular — had about a 50 percent higher risk of metabolic syndrome — a cluster of risk factors such as excessive fat around the waist, low levels of “good” cholesterol, high blood pressure and other symptoms.

“When you have metabolic syndrome, your risk of developing heart disease or stroke doubles. You also have a risk of developing diabetes,” said Dr. Ramachandran Vasan of Boston University School of Medicine, whose work appears in the journal Circulation.

Prior studies have linked consumption of sugar-laden sodas with multiple risk factors for heart disease, but Vasan and colleagues also found the link extends to diet sodas.

The results surprised the researchers who expected to see a difference between regular and diet soda drinkers. It could be, they suggest, that even no-calorie sweet drinks increase the craving for more sweets, and that people who indulge in sodas probably have less healthy diets overall.
