Heart palpitations, or irregular heartbeats, are usually harmless and can occur due to the chewing, swallowing, and digestive processes or because of certain ingredients in food. However, recurrent palpitations may indicate an underlying condition such as an abnormal heart rhythm or other conditions affecting the heart. Certain foods and drinks that are high in sodium, sugar, or stimulants like caffeine and theobromine can cause an increase in heart rate. Alcohol can also be a trigger for palpitations, especially for those diagnosed with arrhythmias. Overeating and obesity can also lead to an increased risk of heart disease and higher resting heart rates. Thus, it is important to maintain a healthy weight and control portion sizes, in addition to limiting the consumption of caffeine, alcohol, and foods high in sodium and sugar to prevent heart palpitations.
Characteristics and contributing factors of an irregular heart rate:
| Characteristics | Values |
|---|---|
| Dietary factors | High caffeine consumption, alcohol, spicy foods, red meat, processed foods, baked goods, deli meats, chocolate, energy drinks, tea, and soda |
| Sodium intake | Excessive sodium can lead to high blood pressure and atrial fibrillation |
| Tyramine | Found in aged cheese, soy sauce, salami, and some herbal supplements, it can affect blood pressure |
| Large meals | Eating large portions can lead to heartburn and atrial fibrillation |
| Dehydration | Not drinking enough water can cause an increased heart rate |
| Low potassium levels | Can cause arrhythmia |
| Allergies | Food allergies can cause an increased heart rate and palpitations |
| Lifestyle factors | Stress, anxiety, lack of exercise, obesity, and family history |

What You'll Learn
Alcohol consumption
Alcohol contains tyramine, an amino acid that can affect blood pressure. It is also a source of excess calories, which can lead to weight gain and obesity, increasing the risk of a heart attack or stroke. Alcohol can also negatively impact mental health, making feelings of low mood after surgery worse and longer-lasting.
Excessive alcohol consumption can lead to high blood pressure, heart failure, stroke, and cardiomyopathy, a disorder that affects the heart muscle. Alcohol can also make it harder to manage your weight and can negatively impact your mental health.
Studies have shown that alcohol consumption is a significant predictor of 24-hour heart rate and that the amount of alcohol consumed is highly correlated with the subject's usual weekly intake. This suggests that limiting alcohol consumption may help to reduce the frequency of heart palpitations and improve overall heart health.
If you frequently experience heart palpitations, it is important to seek professional medical advice and make necessary dietary and lifestyle changes.

Sodium intake
A high-sodium diet can lead to hypertension and an increased risk of heart attack, stroke, and heart failure. Sodium intake is linked to high blood pressure, which can cause atrial fibrillation and irregular heartbeats. The average American consumes almost twice the recommended amount of sodium daily. Foods such as deli meats, soup, and pizza are high in sodium.
While sodium intake is essential for maintaining fluid balance and nerve and muscle function, excessive amounts can have detrimental effects on heart health. High sodium intake can lead to increased blood volume and fluid retention, forcing the heart to work harder. This additional strain on the heart can contribute to irregular heartbeats and potentially increase the risk of more severe cardiovascular events.
In addition to its direct impact on blood pressure and heart function, sodium intake can also influence overall cardiovascular health. Excessive sodium consumption can contribute to the development of heart disease, including hypertension and cardiac structural abnormalities. These conditions can further increase the likelihood of experiencing irregular heart rhythms and other cardiac complications.
It is worth noting that while sodium reduction is recommended for heart health, extremely low sodium levels can also have adverse effects. Hypothetically, sodium intake below the recommended daily intake may lead to reduced blood volume and decreased blood pressure, which could potentially cause dizziness, fatigue, and irregular heart rhythms. However, it is rare for individuals to consume insufficient sodium unless they are on restrictive diets or have specific health conditions.

High blood pressure
A diet that is high in sodium and low in potassium, magnesium, and calcium can contribute to high blood pressure. Sodium intake causes an excess of water in the body, which increases blood pressure. On the other hand, potassium, magnesium, and calcium help to balance out the effects of sodium and relax blood vessels, reducing blood pressure. Not getting enough of these minerals in your diet can contribute to hypertension.
Dietary patterns that have been linked to high blood pressure include a diet high in processed and fried foods, red meat, and high-fat dairy products, as well as a diet low in fruits, vegetables, whole grains, and low-fat dairy products. These dietary patterns are often high in sodium, saturated fat, and trans fat, and low in potassium, magnesium, and fiber, which can contribute to elevated blood pressure.
To help lower high blood pressure, it is recommended to adopt a diet that is rich in fruits, vegetables, whole grains, lean proteins, and low-fat dairy products. This type of diet is often referred to as the DASH (Dietary Approaches to Stop Hypertension) diet. The DASH diet focuses on reducing sodium intake and increasing the consumption of nutrients that help lower blood pressure, such as potassium, magnesium, and calcium.
Specific foods that can help lower blood pressure include:
- Spinach, bananas, and avocados, which are rich in potassium.
- Beans, nuts, and whole grains, which are high in magnesium.
- Dairy products, such as skim milk and yogurt, which are good sources of calcium.
- Berries, citrus fruits, and melons, which are high in vitamins and antioxidants.
In addition to following a healthy diet, maintaining a healthy weight, regular physical activity, and limiting alcohol consumption can also help to lower high blood pressure and improve overall cardiovascular health.

Dietary supplements
Nutritional supplements have been linked to an increased risk of arrhythmia, or irregular heart rate. This is due to the adverse side effects of certain supplements, which can cause a disruption in the heart's electrical signals or a short circuit in one of the chambers of the heart. This can lead to a reduction in circulation to the body's organs and, in some cases, result in heart failure or stroke.
Some supplements that have been associated with an irregular heartbeat include bitter orange, ephedra, ginseng, hawthorn, and valerian. Bitter orange is often taken for heartburn, skin health, and weight loss, while ephedra is used for colds, energy, and headaches. Ginseng is another supplement that can cause an irregular heartbeat and is taken for energy. Hawthorn, which is taken for heart conditions, and valerian, taken for anxiety, depression, and sleep, have also been linked to arrhythmia.
Other supplements that may pose heart risks include red yeast rice, which contains monacolin K, an active ingredient identical to that found in the cholesterol-lowering drug lovastatin. L-arginine, a supplement taken to increase circulation, lower blood pressure, and promote erections, may also be dangerous for those with heart disease. Garlic supplements, often taken to lower cholesterol and blood pressure, can increase the levels and effects of some medications, such as blood thinners and cholesterol-lowering drugs, leading to adverse side effects.
While supplements may be beneficial for overall health, it is important to be cautious and understand their potential effects before taking them. Consulting a doctor or healthcare provider is always recommended, especially if you are experiencing heart palpitations or other cardiac symptoms.

Stress and anxiety
While the causes of heart palpitations are varied, anxiety and stress are common triggers. When you feel anxious about a situation, your autonomic nervous system (ANS) kicks in, increasing your heart rate. This is known as the "fight or flight" response. Emotional turmoil triggers the release of stress hormones, which act on the same brain areas that regulate cardiovascular functions such as heart rate and blood pressure.
Heart palpitations from anxiety can feel like your heart is racing, fluttering, pounding, or skipping a beat. These feelings usually subside when anxiety levels lessen. Palpitations that occur frequently or persist for more than a few minutes may not be related to anxiety. If you experience sustained palpitations along with chest pain, trouble breathing, dizziness, or confusion, seek immediate medical attention.
Anxiety disorders promote the stress response, which can influence the same brain systems that regulate cardiovascular functions. People with anxiety disorders experience "ups and downs" that can lead to high blood pressure, heart rhythm disturbances, or heart attacks. Long-term, unrelenting stress can be a precursor to anxiety and depression. Additionally, people with anxiety may adopt unhealthy habits, such as smoking or overeating, which further contribute to cardiac risk.
To manage anxiety-related heart palpitations, it is essential to address the underlying anxiety and reduce stress levels. This can be achieved through various means, including complementary health treatments, lifestyle changes, and medical interventions. Complementary health treatments, such as biofeedback, massage therapy, and mindfulness exercises like yoga, meditation, or deep breathing, can effectively help manage stress and anxiety. Maintaining a healthy weight, exercising regularly, and making dietary modifications can also improve cardiovascular health and reduce anxiety. In some cases, healthcare providers may recommend antidepressant medication or other medications to treat anxiety and its associated symptoms.
