Can Eating Bananas Trigger Headaches? Here is the Answer!

Let’s start the article by providing a short answer to the question asked in the title. Yes, bananas may trigger headaches in some people, especially in those who are prone to migraines.

Hearing that bananas may lead to headaches may come as a surprise to many people. After all, bananas are loaded with essential nutrients and are known to offer a variety of health benefits.

If you are surprised to hear that eating bananas may cause headaches, then what about the following facts:

  • Broccoli may increase the risk of developing blood clots in people who are on blood thinners because of its high vitamin K content [1, 2].
  • Tomatoes may cause heartburn in those who are prone to it.
  • Dried fruits can lead to insomnia if eaten excessively.
  • Almonds may increase the risk of calcium oxalate kidney stones if eaten regularly and in high quantities [3, 4].

The goal of giving these examples is to remind you that even healthy foods can cause some side effects in some people. Nevertheless, they are healthy for your body and their side effects impact a small number of people.

The same logic applies to bananas. Although bananas might be a potential headache trigger for some people, particularly for migraine patients, they can contribute to your health in several ways with their rich nutrient content.

Besides, bananas would never be one of the most popular fruits around the world if they caused headaches in many people [5, 6].

Bananas and Headaches

If you are wondering why you often experience headaches after eating bananas, you should know bananas might be a headache trigger for you.

“Ripe bananas can be potent headache triggers,” says Jennifer Kriegler, MD, of the Center for Neurological Restoration at the Cleveland Clinic. 

Doctor Jennifer Kriegler especially indicated “Ripe Bananas “. Are ripe bananas more likely to cause headaches compared to unripe ones? The answer is yes!

Until this point we have learned two things:

  • Bananas can cause headaches, especially in migraine sufferers.
  • Ripe bananas are more likely to trigger a headache compared to unripe ones.

It appears that eating ripe bananas may give you a headache especially if you are susceptible to migraine headaches.

There are now two questions to ask, which are;

  • What makes bananas a potential headache trigger?
  • Why are ripe bananas more likely to cause headaches compared to unripe bananas?

Let’s dive in and provide evidence-based answers to these questions.


Foods and Headaches

Almost all of us experience headaches. While many of us experience it from time to time, others get headaches more frequently.

If you don’t get any headaches in a year, you should consider yourself quite lucky. Because a report published by the WHO says that approximately 75 per cent of people experience headaches at least once a year.

While normal “everyday” headaches are somewhat bearable, a migraine headache can be quite severe and can last for hours. Various reports show that around 1 billion people worldwide suffer from migraines [7, 8].

Hormonal changes, stress, alcohol and cigarette use, not drinking enough water, certain medical conditions, some medications, neurological problems and many other things can cause headaches, according to medical experts [9, 10, 11, 12, 13].

Strangely, even your gender can make you more susceptible to headaches! Sadly, if you are a woman you are three times more likely to have migraines [14, 15, 16].

What’s quite related to our topic is the fact that certain foods as well can lead to headaches.

According to an article published by Cleveland Clinic; about 20% of headache patients are thought to be food-sensitive.

In the same article, it was also published a list of foods that are likely to cause headaches. And, bananas (ripe bananas) are indeed on the list.

The Cleveland Clinic indicated: “It’s important to note that most of the information about possible food triggers of headache come from patient self-reports and not from randomized scientific studies.”.

So, one thing is clear now! Headaches can also be triggered by certain foods including healthy ones such as garlic, onions or bananas.


What Makes Bananas Potential Headache Triggers?

The answer is tyramine, which is a natural compound that occurs when the amino acid tyrosine is broken down [17, 18, 19].

Tyramine is found in certain foods and one of these foods is bananas.

As a matter of fact, scientists are still trying to understand in what way this natural compound cause headaches. But, they are well aware of the correlation between headaches and tyramine.

According to WebMD, scientists began to realise the migraine-triggering effect of tyramine first in the 1950s, after people who took antidepressant drugs – which inhibit monoamine oxidase – started getting headaches and experiencing high blood pressure.

Here is more detail…

Normally, monoamine oxidase breaks down tyramine. However, since anti-depression drugs inhibited monoamine oxidase that breaks down tyramine, tyramine levels remained high in the bodies of those who were using the drugs, causing certain problems like high blood pressure and headaches [20, 21, 22].

Thus, scientists began to realise the relationship between a high level of tyramine and headaches.

It might be quite hard to comprehend this process since most of us are not familiar with the terms like tyramine or monoamine oxidase.

But, what you should know is that if tyramine is high in your body, you may experience symptoms like high blood pressure and headaches [23, 24, 25].

It is important to note that even if you are not prone to having migraines, too much tyramine can still give you a headache.

The problem is that bananas are rather high in this natural compound namely; tyramine.

Especially, ripe bananas have more tyramine compared to unripe ones [23]. Therefore, they are more likely to trigger migraines.


How to Know Whether Bananas Give You a Headache?

Now, it is crystal clear that bananas can cause headaches owing to their high tyramine content.

Thus far, we also learned that ripe bananas are more likely to trigger migraines compared to unripe ones. This is because they contain more tyramine than unripe ones.

The question is how can you know whether or not bananas are the culprit that gives you headaches?

According to the Cleveland Clinic: the most common and practical way to identify which foods or beverages give you a headache is to keep a diary of everything you consume during the day.

If you almost always get headaches 20 minutes to 2 hours after consuming a particular food (for instance, a banana) that may signify that particular food is a headache trigger for you.



Almost all of us experience headaches from time to time. It is unfortunately quite a common problem around the world.

In this article, we tried to figure out whether bananas can cause headaches in some people.

What we found out is that since bananas are high in tyramine, they may lead to headaches, especially in people with migraines.

That indicates not only bananas but also other foods high in tyramine such as avocados, aged cheeses, cured meats, and soybeans can also make the same impact.

Whether bananas or anything else, whatever the cause of your constant headaches which lowers your quality of life, we encourage you to work with your doctor to find out the underlying causes and also to determine the best treatment method.

Allow your medical provider to find out the cause/causes of your constant headache and apply the best treatment for you accordingly.
