74 g/day) and then assessed for new cases of AFib. The average protein intake was 60 grams/day, with women who ate between 58 and 74 grams a day having significantly less risk of AFib. This relationship remained even after adjusting for age, ethnicity, education and other cardiovascular conditions and risk factors such as body mass index, physical activity, tobacco and alcohol use, high blood pressure, high cholesterol, diabetes, coronary and peripheral artery disease, and heart failure. Interestingly, women typically underestimated their daily protein intake by about 10 grams and caloric intake by 600-700 calories, which speaks to the need for more nutritional awareness and education, researchers said. "Based on our findings, it seems that eating more protein may not only help strengthen women physically, but it may also have cardiovascular benefits in terms of reducing AFib and related death, strokes and heart failure," Gerber said. "About 1% of the U.S. population has AFib and, with an aging population, it is projected to increase several-fold by 2050, so doing something as little as eating an extra few grams of protein a day could potentially have a huge impact across the population." This study builds on earlier research by the same research team, which unexpectedly found that lean body mass was a much stronger driver for new AFib than obesity. Gerber said high protein diets have been closely correlated with lean body mass, so the hope of this study was to explore the effect of protein intake on developing AFib. This study is limited in that it is retrospective and observational. Future research should address whether modifying protein intake can prospectively reduce AFib incidence and uncover what factors are driving this relationship." />

Daily Protein Intake Linked to AFib in Women

Women who ate slightly more than the recommended daily amount of protein were significantly less likely to develop atrial fibrillation (AFib), a dangerous heart rhythm disorder that can lead to stroke and heart failure, when compared with those who consumed less protein, according to research being presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology (ACC.20/WCC). This is the first study to investigate protein as a possible nutritional driver for AFib, which is more common with age.
