3 Foods that Cause Heart Palpitations

Often when I write about the best and worst foods for the heart, I talk in the context of heart-healing foods that are good to eat, as well as foods that should be avoided because they fan the flames of inflammation. Those discussions focus on how the things we eat and drink every day affect heart health over the long haul.

Today, though, I want to shift gears and focus on foods (including beverages) that can have more immediate and noticeable impacts on the heart—starting with foods that can cause heart palpitations. In this article I’ll explore:

And be sure to check out the latest (and last) article in my heartbeat series:

6 Natural Ways to Stop PVCs (Premature Ventricular Contractions)

Why Foods Cause Heart Palpitations

Feeling palpitations after eating is a relatively common experience, which tends to occur when a substance in your food or drink—or your body’s natural biochemical response to that substance—jolts the heart’s electrical system and causes fluttering sensations, skipped beats, or a feeling that your heart is beating too hard or too fast.

Coffee drinkers, think about the last time you drank one cup too many. You know what I mean!

If your heart is healthy and you have no history of arrhythmia or heart disease—and you’re not experiencing any other symptoms—there’s little need to worry about an occasional episode of these irregular beats. For people who do have arrhythmias or cardiac issues, however, it’s a different story. Palpitations caused by food can cause an existing disruption in your heart’s rhythm to escalate, and potentially lead to a major event.

Foods That Cause Heart Palpitations: An Unholy Trinity

If you’ve had a heart attack or other cardiac event, have abnormalities in the shape or function of your heart, or have been diagnosed with an arrhythmia of some kind, I recommend staying away from foods that cause heart palpitations—especially these three:

1. Caffeinated Foods / Beverages

The research around caffeine is a little less definitive since a study released at the start of 2016 found no relationship between caffeine consumption and palpitations. However, those results don’t change the fact that caffeine revs up your sympathetic nervous system and spikes your levels of stress hormones (namely, adrenaline and cortisol), raising your blood pressure and increasing your heart rate. Caffeine also acts as a diuretic, which can wash away your potassium and magnesium stores, creating an electrolyte imbalance that disrupts the heart rhythm.

In my experience, placing extra stress on the heart—as caffeine does—can aggravate existing arrhythmias or cause new ones. One of the reasons beta blockers are prescribed to heart attack patients is that they help control heart rate and prevent sudden changes in heart rate and rhythm by blunting the effect of the stress hormone adrenaline.

For those of you with healthy hearts, your daily dose of coffee, tea, or chocolate probably won’t cause any harm. Beware, though, of caffeine-containing energy drinks, which are particularly popular with young people. These drinks, which combine caffeine with large amounts of sugar, have been linked with heart palpitations, arrhythmia, heart attack, and sudden cardiac death in adolescents and young adults.

2. Sugar

In addition to creating inflammation in the body, sugar is a stimulant with the ability to cause heart palpitations. The most obvious example is when you eat too much of it at one time. Initially you feel a “sugar rush,” which can cause palpitations. Later, you may also feel them when your blood sugar comes crashing back down, often to a level lower than normal.

Eating smaller portions of sugar-filled foods each day can put you at risk for palpitations as well, because it causes fluctuations in blood sugar levels. Low blood sugar is a common cause of racing skipped heart beats. Lower your risk by minimizing sugar consumption.

3. Alcohol

The link between alcohol and heart palpitations and arrhythmia is well documented. In fact, occurrences with binge drinking are so common that there is even a name for it: Holiday Heart Syndrome. The term refers to otherwise healthy people who suffer atrial or ventricular arrhythmias (often ventricular tachycardia) when they overindulge.

Obviously, if alcohol can have such an effect on a healthy heart, anyone with compromised heart health should abstain—even if it’s just one glass of wine. The risk is just too high.

What to Do if Foods Cause You Heart Palpitations

First off, take note if you feel any additional symptoms, because those could signal that you’re experiencing more than simple palpitations. Seek emergency medical help if at any point you also have:

  • Shortness of breath
  • Profuse sweating
  • Dizziness or lightheadedness
  • Loss of consciousness
  • Chest pain or pressure
  • Pain or discomfort in the upper back, arms, neck, or jaw
  • Feeling of impending doom

If it’s the first time you’ve ever noticed heart palpitations, make a follow-up appointment with your doctor. It’s likely nothing is wrong, but it’s always best to err on the side of caution and make sure that the food-related episode isn’t the first sign of a bigger issue.

Next, start a log and record times when the palpitations recur. Note what you ate or drank and what sort of emotional state you were in. If specific foods or beverages tend to cause recurrences, take that as a sign you should reduce or eliminate those foods from your diet. Your body and your heart couldn’t be telling you any more clearly that those substances are doing you harm.

Opt for Healthy-Heart Foods Instead

Just as there are foods that cause heart palpitations, there are “healthy-heart” foods that may help prevent them. Here are four of my favorites:

Wild-Caught Salmon

I love wild-caught salmon—it’s one of my Sinatra Super Foods for its heart health benefits. Salmon is rich in omega-3 fatty acids, which have a calming, anti-inflammatory effect on the heart and vascular system. Omega-3s also have been shown in studies to protect against sudden cardiac death caused by arrhythmias.

Nuts and Seeds

Since one underlying cause of arrhythmia and palpitations is electrolyte imbalance, it’s a good idea to up your intake of magnesium-rich nuts and seeds. Magnesium is a key electrolyte needed for more than 300 biochemical reactions in the body.

Green Leafy Vegetables

Spinach, kale, chard, and other green leafy vegetables are also rich sources of magnesium and heart-healing foods.


Avocados bring you the best of two worlds. They are good sources of magnesium, as well as potassium—another key electrolyte. You probably know bananas and citrus fruits to be a top source of potassium, but I like avocados because they also supply the body with a lot of healthy fats. Though fruits are certainly part of any healthy diet, they’re much higher in sugar.

    I like that you came quickly to the point. Some of this information comments require hours of reading before they come to the point. Of course I give early in the story up.

    I love to learn and am most appreciative when a teacher knows what he/she wants to say and then does a check at the end to see if the objective has been achieved. at the end of each paragraph ask your self what did I want to teach and second did i teach it?

    the method I love and appreciate the most is to ask the question followed by the answer (this way we all know what we are talking about) and we know the question and the correct answer. the important part of teaching is the “WHY” Spend the lines of the paragraph telling WHY this is the correct answer.
    take the following as an example from your article; “Foods That Cause Heart Palpitations: An Unholy Trinity” what did you want to say ? what did you want me to learn from the correct answer?
    Your paragraph should have been all about why the answer you gave is correct.
    You will not have wasted my time and you will have communicated truth from your vast knowledge,
    try it you will love it.

    I was diagnosed with A-fib (I think “persistent”)and had an ablation three weeks ago. What can I do to make the ablation hold? I am a 59 year old female. I have cut back on caffeine. I take 400 mg of magnesium glycinate and 250 mg of magnesium taurate daily.

    I have noticed that every time I eat eggs I have heavy palpitations and feel sick . Can you please tell me if I have an allergy to egg ? Is this normal or not? I do like eggs, I have no rashes or any breathing problem. I eat cake that contains egg and no problem there whatsoever.

    Hi Ingrid,
    I have A Flutter and have had three episodes to date two of which required cardioversion. All three times I had eaten a meal containing eggs, a quiche on the first two occassions and an egg sandwich on the third. Now when I eat eggs especially on their own I notice I get palpitations and feel unwell. Hence I have decided it’s time to give up the eggs along with other potential triggers. Somehow the eggs just don’t seem to agree with me. Stress also seems to play a part in my episodes.

    I eat Apple and popcorn, popcorn is popped in olive oil and salted with pink salt…too many times this brings on palpitations. Any suggestions?

    Sorry…I meant to say too many times this brings on heart palpitations

    Hi Barbara,

    This is unusual, however, corn is a top genetically modified crop. You may be having an unknown reaction to the GMO corn or to the pesticides used on this crop. Pesticides could also be the culprit with the apple, so be sure to get organic whenever possible. Additionally, make sure the amount of salt you use on the popcorn is very low and your portion size is small because an increase in blood sugar can bring on palpitations.

    Can cucumbers also be a good thing to eat if I’m having heart palpitations


    on June 29, 2017 at 12:33 pm

    Of course. And in all due respect, for whatever reason, you do not recognize or talk about the damage that olive oil and all kinds of all oils – raw or cooked – do to our arteries…. how they inflame, aggravate, and irritate them, how they shred the endothelial cells, and how this triggers heart attacks and death. It also causes angina too. This bewilders me. Instead, you continue to say and promote that olive oil is good for the heart. I don’t get it. I emailed you several times regarding this to no avail.

    In response to JEFFREY R. STEIN’s comment above: With all due respect, Mr. Stein, Dr. Sinatra wholeheartedly DISAGREES with your position about olive oil, but believes that everyone has a right to state their opinion and encourages a forum of ideas here at HeartMD Institute. Do you have any scientifically credible evidence to back your position on olive oil? One of the reasons that Dr. Sinatra likes olive oil so much is that there have been so many studies, such as Predimed, demonstrating it’s health benefits – you can learn all about those health benefits and click on links to just some of those studies at https://heartmdinstitute.com/diet-nutrition/olive-oil-a-superfood-more-super-by-the-minute/ . Also, Mr. Stein, I also just checked our email database, and there is no record of the emails you claim to have sent- we have not received any emails from you. If you would like to email us, please send an email to [email protected]. Please know that due to the sheer volume of emails we receive daily, we cannot respond individually to each one. Best wishes.

    To JEFFREY R STEIN, I personally agree with you that there are some oils that you should stay away from. Like for example corn and soybean oil due to gmo’s. But oils like raw organic cold pressed extra virgin unrefined olive oil and coconut oil is proven to have health benefits and so does flaxseed oil due to the omega 3 fatty acids.

    Do you know of any studies that have been done to further look into foods that cause palpitations? Do you have an idea how soon after the palpitations can occur? Does the rapidity indicate if the pathogenesis of the reaction is a blood sugar rush/increase or a food allergy response?
    I am asking these questions because i am getting palpitations to ‘healthy foods’ such as small amounts of sunflower seeds, raisins, black eyed beans and i am trying to determine what the cause is as i am gradually discovering my food choices are becoming very restricted.

    The problem with all these fora is that contributors just warble on in a self-interested way about things they think are true based on mumbo-jumbo without a shred of evidence. Good health, including that holy grail: a steady heart rhythm , is a state of organised biological chaos so who knows what makes a difference or helps a particular condition? Olive oil? Dont be ridiculous! All I look for are specific, supported diet experiences that another person may report. In as few words as possible. I have had three ablations and two thoracotomies over the last 20 years for, or associated with, AF and I still don’t really know what triggers each episode, which may last for days or weeks. I wondered if hot chillie peppers, which I am fond of, can be implicated but I dont find anyone else reporting this.

    I had ablation about 17 years ago having suffered supratachycardia since I was little which finally resulted in arrythmia. I was thankfully off the drugs and symptom free until a few days ago when the fluttering pigeon in my chest returned. After an ecg comfirming extra beats, the doctor is referring me back to the cardiac specialist for advice but I do not want to go back to drugs. I had a bad day, then a day without symptoms and thought it had gone away. However, I had cheese on toast last night and a glass of red wine and the flutters are back. I am wondering now if it is either cheese or the red wine which has prompted the return of the ectopic beats. I have been having a glass of red wine for years with no affect but now concerned that maybe I will have to give that up or the cheese.
