Salty and processed foods
Table salt, which is essentially sodium, can increase your risk of AFib because it raises your blood pressure. People who have high blood pressure are often advised to limit their salt consumption when to keep their blood pressure under control. High blood pressure itself is an AFib risk factor.
While you cannot eliminate sodium from your diet, you should avoid consuming foods rich in it. Choose foods with no added salt and steer clear of processed foods that use salt as a preservative or seasoning.
Research shows [9] that excess salt consumption can increase the frequency of AFib episodes. You already get the amount your body needs from your regular diet. You should not consume more than 2.3 grams [10] daily.
