Chinese researchers have found that consuming more than two liters of diet soda or other artificially sweetened drinks per week could increase the risk of atrial fibrillation by 20% compared to those who drink none. The study, conducted in Shanghai, highlights a potential link between low-calorie beverages and the dangerous irregular heartbeat condition.
Atrial fibrillation, or A-fib, is described by cardiologist Dr. Theodore Maglione as a chaotic quivering of the heart's upper chambers. Symptoms include fatigue, shortness of breath, and palpitations. While genetics and age are uncontrollable risk factors, modifiable ones include smoking, hypertension, sleep apnea, obesity, and nutrition.
The study also examined added-sugar beverages and pure unsweetened juices. Added-sugar drinks were associated with a 10% increased risk of A-fib, while consuming about four ounces of pure unsweetened juices, such as orange juice, was linked to an 8% lower risk. Dr. Maglione emphasized that a heart-healthy lifestyle, including diet and exercise, can reduce recurrence rates after treatment.
Atrial fibrillation can lead to blood clots, strokes, and other heart complications. The US Centers for Disease Control and Prevention notes that stroke is a leading cause of serious long-term disability, with A-fib being the leading cause of stroke in the United States. Those over 65 are at greater risk and should avoid artificially sweetened drinks.
Dr. Maglione advised anyone experiencing symptoms of irregular heartbeat to seek medical care, as early intervention improves treatment success and prevents complications like stroke.
