Atrial fibrillation, or AFib for short, is a condition that causes an irregular heartbeat. Certain foods, such as caffeine or alcohol, have the potential to trigger AFib. A diet that promotes heart health may help manage and reduce the symptoms of this condition.
A suitable diet may also decrease the risk of developing other heart conditions alongside AFib, including heart disease.
In this article, we explore what AFib is, foods to eat and avoid, exercise techniques, and other potential tips for managing this condition.
AFib is a type of arrhythmia that affects the upper chambers of the heart. The electrical impulses that control these chambers fire in a disorganized way, which leads to an irregular heartbeat.
AFib itself is not a life threatening condition. However, it can increase the risk of stroke, blood clots, and congestive heart failure.
- having overweight
- high blood pressure (hypertension)
- alcohol consumption
- obstructive sleep apnea
- high cholesterol
- having a family history of AFib
There is no cure for AFib. Some people may require medication, cardioversion, a pacemaker, or catheter ablation to manage the condition.
There is also
The benefits of the Mediterranean diet for AFib include:
Overall heart health
A study in
Platelets are blood cells that help the body form clots to stop bleeding. A 2015 study found that the Mediterranean diet can positively affect platelet function for people who have AFib.
The Mediterranean diet may lower cholesterol levels. As high cholesterol is a risk factor for AFib, someone who lowers their cholesterol will reduce their chances of developing the condition.
Reduced risk of heart attack and stroke
According to a 2015 study, the Mediterranean diet may reduce the risk of someone with AFib having a heart attack or stroke.
Although these diets may have a positive effect on AFib, if someone wishes to change their food habits, they should discuss their options with a registered dietitian first.

Each meal should contain a good portion of vegetables, a source of protein, a complex carbohydrate, and unsaturated fat. In addition to olive oil, this fat may include avocado oil, flaxseed oil, or hemp seed oil.
If a person needs inspiration for potential meals under the Mediterranean diet, the
If a person is vegetarian or vegan, they can follow a more general plant-based diet consisting of vegetables, fruits, whole grains, legumes, and proteins from nonanimal sources.
Foods to avoid may include those that directly trigger symptoms and raise the risk of heart disease and cholesterol. These include:
Caffeine and energy drinks
A 2014 study found that even moderate alcohol intake could be a risk factor for AFib. Therefore, it may be advisable to limit or avoid alcohol.
In general, red meats such as beef or lamb tend to have higher amounts of saturated fat than white meat. Saturated fat can raise cholesterol levels, which is a risk factor for AFib. A person who substitutes red meat for plant-based protein may
Processed foods, such as ready meals or sausages, tend to have large quantities of salt and preservatives. It may be best to limit the intake of these as they can adversely affect the heart.
Sugary foods and drinks
People should avoid foods and drinks that contain a large amount of sugar, as these can trigger AFib episodes. Sugary foods also
Someone may have
If a person follows the Mediterranean diet, they will also need to limit much of the same foods listed above.
There is some evidence that very low carb diets, such as the keto diet, may increase the risk of AFib. However, researchers need to carry out more studies to confirm and understand these findings.
In addition to diet, exercise may also help manage AFib risk factors, such as obesity and hypertension.
Research suggests that even a small amount of
A person with AFib can consider doing low impact exercises, such as walking, light jogging, or swimming. They should start slowly and build up gradually so they can exercise several times per week.
Some people with AFib may have a pacemaker. A person who has recently had a pacemaker fitted should avoid strenuous exercise for 4–6 weeks. After this time, they can continue most sports and activities, but they must take precautions in contact sports, such as football or boxing. It is also advisable to avoid strenuous sports, including squash.
Anyone with questions about how soon they can take part in sports after having a pacemaker fitted should talk to their healthcare provider.
There are several other ways a person with AFib can adjust their lifestyle to promote heart health.
People who smoke are
Manage sleep conditions
Sleep deprivation, obstructive sleep apnea, and other sleep disorders may increase the risk of AFib coming back after someone has undergone ablation or cardioversion. The management of sleep apnea and stress may help a person improve the quality of their sleep.
Stress, anger, and anxiety have a significant effect on AFib. One study reported an 85% drop in AFib symptoms after people reported feeling happy. Regular relaxation and stress reduction through activities like yoga may help someone manage these emotions.
Learn about other activities and natural remedies that may help with AFib.
AFib causes an irregular heartbeat. Several risk factors, such as obesity, high blood pressure, and diabetes, make it more likely that a person will develop AFib.
Diet can help reduce the risk factors that cause AFib and, in some cases, reduce its symptoms. The Mediterranean diet or a plant-based diet with plenty of fruits, vegetables, and unsaturated fats may benefit overall heart health, lower cholesterol, and reduce the risk of a heart attack.
Other changes that may improve AFib include doing moderate exercise several times per week, getting high quality sleep, stopping smoking, and prioritizing time to relax and reduce stress.
