Keto, Paleo, Atkins — there’s no shortage of low-carb diets to try, but new research suggests that over time, living low-carb can raise your risk of a heart condition called atrial fibrillation, or a-fib. People who regularly got fewer than 45 percent of their calories from carbohydrates were 18 percent more likely to develop a-fib than people who ate a moderate amount of carbohydrates (about 45 percent to 52 percent of their calories). The Chinese researchers said the risk of a-fib was raised no matter what types of protein or fat were used to replace carbohydrates. “Extremes of anything aren’t good. Too much carbohydrate is bad and too little is also bad,” explained Dr. Laurence Epstein, system director of electrophysiology at Northwell Health in Manhasset, N.Y. Epstein wasn’t involved with the new study. Atrial fibrillation is a heart rhythm disorder. Instead of the usual heartbeat, the heart sometimes quivers in people with a-fib. Because the heart isn’t pumping properly, blood pools in the heart and can form clots. If a blood clot breaks free, it can reach the brain and cause a stroke, according to the American Heart Association. Although the current study was only designed to find an association, and not a cause-and-effect relationship, Epstein pointed to several reasons a low-carb diet could have negative consequences. He said that one way low-carb diets cause… read on >
