MSG Heart Palpitations: What You Need to Know
Monosodium glutamate (MSG) is a common food additive that enhances flavour in a variety of dishes. While it’s often found in processed foods and restaurant meals, many people worry about its effects on their heart. You might have heard that MSG can cause heart palpitations, leaving you feeling like your heart is racing or fluttering.

It’s important to know that while some people report feeling heart palpitations after consuming MSG, researchers have not found clear proof that MSG directly causes these symptoms. Most reactions to MSG, like flushing and headaches, fall under what’s known as MSG symptom complex but are not well-understood.
So, what should you do if you’re concerned about heart palpitations after eating foods with MSG? Paying attention to your diet and how you feel after meals can help you manage and understand your reactions. Continue reading to learn more about what might be causing your heart palpitations and how to address them in your daily life.
Key Takeaways
- MSG is a food additive sometimes linked to heart palpitations.
- No clear evidence proves MSG causes heart palpitations.
- Pay attention to your diet to manage potential triggers.
Understanding Heart Palpitations

Heart palpitations are feelings of a rapid, fluttering, or pounding heartbeat that can be caused by various factors like stress, food sensitivities, and medical conditions. Recognising symptoms and knowing when to see a doctor is crucial.
Causes and Triggers
Heart palpitations can be triggered by stress, anxiety, and strenuous physical activities. Certain foods and drinks, especially those high in caffeine, alcohol, sodium, or MSG, can also cause palpitations. Panic attacks and excessive sugar intake can play a role too. Some medications and hormonal changes during pregnancy or menopause may also contribute. More serious causes include underlying heart conditions like arrhythmias or heart valve disorders. Even changes in your blood pressure and thyroid disease can be reasons.
Recognising Symptoms
Heart palpitations often feel like your heart is racing, pounding, or skipping beats. You might sense this not only in your chest but also in your neck or throat. Other symptoms include shortness of breath, dizziness, numbness, and tingling. Some people experience chest pain or a sensation of fluttering. Flushing can also occur. If you notice these symptoms frequently, especially if they get worse or last longer, it’s important to monitor them.
When to See a Doctor
You should see a doctor if your heart palpitations come with severe chest pain, shortness of breath, or fainting. If palpitations are new and persistent, or if you have a history of heart disease, seeking medical advice is essential. Palpitations accompanied by numbness, tingling, or severe dizziness also warrant a doctor’s visit. Keeping a record of your symptoms, including when they occur and what you were doing at the time, can help your doctor diagnose the issue.
Diagnostic Tests
Doctors use several tests to diagnose heart palpitations. An electrocardiogram (ECG) records electrical signals from your heart to check for arrhythmias. A Holter monitor may be used to track your heart rate over 24 hours. Blood tests help identify conditions like thyroid disease that might cause palpitations. Monitoring your blood pressure, heart rate, and oxygen levels also provides essential information. For more detailed imaging, an echocardiogram or stress test may be conducted.
MSG and Diet’s Impact on Heart Palpitations

This section explores how monosodium glutamate (MSG) and your overall diet can affect the rate of heart palpitations, the sodium content in foods, and the importance of healthy eating habits in managing symptoms.
Understanding MSG
Monosodium glutamate, commonly known as MSG, is a flavour enhancer often found in processed foods and restaurant meals. It’s a sodium salt that brings out the umami taste, which resembles the savoury flavour found in mushrooms and soy sauce.
While MSG is generally recognised as safe by many health authorities, some people are sensitive to it. This sensitivity can lead to short-term reactions such as headaches and heart palpitations. If you notice symptoms, it’s wise to check food labels for MSG, yeast extract, or glutamic acid to help identify potential triggers.
Food and Heart Palpitations
Certain foods can influence your heart rate. For instance, foods high in sodium, sugar, and caffeine may increase the likelihood of experiencing heart palpitations.
Processed foods often contain high levels of sodium, which can raise blood pressure and force your heart to work harder. Sugary foods and drinks can cause rapid changes in blood sugar levels, leading to similar effects. Additionally, foods eaten at restaurants, especially fast food, can be high in these ingredients, making them a common culprit for heart palpitations.
Healthy Eating Habits
Adopting healthy eating habits can significantly mitigate the impact of dietary triggers on your heart. Focus on a balanced diet with plenty of fruits, vegetables, whole grains, and lean proteins.
Avoid processed foods and opt for home-cooked meals where you can control the ingredients. Keeping a food diary can help you track what you eat and identify any patterns between your diet and heart palpitations. Reducing intake of sodium and sugar is essential, as well as staying hydrated by drinking plenty of water.
Managing Symptoms
If you experience heart palpitations, it’s crucial to speak with your doctor to rule out any underlying health conditions. They might recommend lifestyle changes, such as reducing stress and avoiding known dietary triggers.
For some, simple treatments like deep breathing exercises or resting in a quiet environment can alleviate symptoms. In more severe cases, medications might be prescribed. Keeping track of your symptoms and diet can help you and your doctor determine the best course of action.
