Consuming two liters or more of diet soda per week can increase your risk of developing atrial fibrillation, a new study says.

The study, published Tuesday in the journalCirculation: Arrhythmia and Electrophysiology, examined approximately 202,000 people from the United Kingdom aged 37 to 73. Researchers found that individuals who consumed more than two liters of artificially sweetened drinks, equivalent to six standard 330ml cans, were 20% more likely to develop atrial fibrillation.

According to theCenters for Disease Control, atrial fibrillation occurs when the heart beats too slowly, too fast or irregularly. Other symptoms of the condition include lightheadedness, extreme fatigue, shortness of breath and chest pain. Atrial fibrillation is also theleading cause of strokein the United States.

“Our study’s findings cannot definitively conclude that one beverage poses more health risk than another due to the complexity of our diets and because some people may drink more than one type of beverage,” said lead study author Dr. Ningjian Wang, a professor at the Shanghai Ninth People’s Hospital and Shanghai Jiao Tong University School of Medicine in Shanghai, China.

“However, based on these findings, we recommend that people reduce or even avoid artificially sweetened and sugar-sweetened beverages whenever possible,” Wang continued in the statement. “Do not take it for granted that drinking low-sugar and low-calorie artificially sweetened beverages is healthy, it may pose potential health risks.”

Penny Kris-Etherton, a professor emeritus of nutritional sciences at Pennsylvania State University, added that this is the first study to report an association between no- and low-calorie sweeteners and also sugar-sweetened beverages and increased risk of atrial fibrillation.

“We still need more research on these beverages to confirm these findings and to fully understand all the health consequences on heart disease and other health conditions,” Etherton, who is also an American Heart Association nutrition committee member, added in apress release. (She did not participate in the research of the study.)

“In the meantime, water is the best choice, and, based on this study, no- and low-calorie sweetened beverages should be limited or avoided,” she continued.
