A lot of it is about the relationship between bad lifestyle habits and arrhythmias, such as smoking and drinking alcohol. Some friends ask us, then there is no life habits, can prevent arrhythmia it? Today we will talk to you about eating “nuts” regularly, which can help us prevent atrial fibrillation. Recently, a study of nearly 820,000 people published in BMCMedicine showed that at least 20 grams of nuts a day, can greatly reduce the risk of heart disease, cancer and many other diseases. So what is good for the heart, exactly? A recent study of more than 60,000 people (Swedes) published in Heart showed that eating a few servings of nuts each week can help reduce the risk of atrial fibrillation (AF). Atrial fibrillation, one of the most common heart arrhythmias. The risk of stroke is five times higher in people with atrial fibrillation than in the general population. Studies have shown that eating nuts can help reduce the risk of heart attack, heart failure, atrial fibrillation and abdominal aortic aneurysm after taking age and gender into account. However, when lifestyle, diet, diabetes and family history were further considered, it was shown that eating nuts only reduced the risk of atrial fibrillation and heart failure. Eating nuts to prevent atrial fibrillation also shows a quantitative-effect relationship. For example, eating 1 to 3 times a month can reduce the risk of atrial fibrillation by 3%; while if you eat 1 to 2 times a week nuts, you can reduce the risk of atrial fibrillation by 12%; if you eat ≥ 3 times a week nuts, you can reduce the risk by 18%. And eating an extra serving of nuts per week reduced the risk of atrial fibrillation by 4%. In this study, however, those who ate nuts were more educated and had healthier lifestyles, and rarely smoked or had a history of high blood pressure. They loved sports, were fit, and ate more fruits and vegetables, although they also often drank alcohol. The researchers noted that people who ate nuts had fewer cardiovascular risk factors or influenced the study results, but their study sample size was larger and nuts are rich in minerals and antioxidants, both of which are beneficial to cardiovascular health. Of course, nut consumption is only one of a healthy lifestyle, although there is a certain role in preventing atrial fibrillation, but also to ensure that other lifestyles are also healthy. For example, regular exercise, avoid sedentary, eat more fruits and vegetables, actively control blood pressure, lose weight to keep fit, etc.. Only if all of the above are done will the incidence of atrial fibrillation be greatly reduced.
