Citrus and Migraines

Headaches can be caused by a variety of factors, including stress, hormones, and diet. One lesser-known trigger for headaches is citrus fruits. Studies have shown that consuming certain citrus fruits such as oranges or grapefruits can lead to migraines in some people. While the exact cause behind this phenomenon is still unclear, understanding what citrus fruits can do to our bodies can help us manage migraines more effectively. Let’s discuss how Citrus and Migraines are connected and what you can do to reduce the risk of experiencing a migraine due to consuming citrus.

Learning How to Live with Chronic Migraines can be challenging, but there are ways to make it more manageable. One of the most important things is to develop a routine that works for you. This can include setting regular sleep and meal times, avoiding triggers such as bright lights or certain foods, and incorporating relaxation techniques such as meditation or yoga. It’s also important to communicate with your doctor and loved ones about your condition, and to have a support system in place. Remember, although chronic migraines may be a part of your life, they don’t have to define it. By taking control and making changes that work for you, you can still live a fulfilling and enjoyable life.

What are Migraines?

Migraine is a neurological condition that affects the brain, causing severe headaches and other symptoms. Many people with migraine have recurring attacks of headaches, while others have headache pain only occasionally. The attacks are often disabling and can be accompanied by nausea, vomiting, or sensitivity to light or sound.

Migraine attacks are believed to be caused by changes in brain function, possibly triggered by environmental factors such as stress and diet. These triggers may cause blood vessels in the brain to dilate (open wider) or constrict (tighten), which can affect blood flow to the brain and cause pain.

Triggers may include:

  • Stress
  • Hormones (such as those released during menstruation)
  • Bright lights, loud sounds or certain smells
  • Alcohol use

How Does Citrus Trigger Migraines?

Citrus fruits contain a high level of histamine, which is a naturally occurring compound that plays a role in the immune system’s response to allergens. Histamine is also involved in the regulation of blood flow and inflammation in the body, which are thought to be contributing factors in migraine headaches.

In addition, citrus fruits contain high levels of tyramine, a compound that is also found in aged cheeses, red wine, and other fermented or aged foods. Tyramine has been known to trigger migraines in some people by causing the release of the neurotransmitter norepinephrine, which can lead to changes in blood pressure and blood flow to the brain.

Furthermore, citrus fruits are acidic, and their consumption can lead to a drop in the pH level of the body. This acidity can cause the release of substance P, a neuropeptide that is involved in the transmission of pain signals in the body. The release of substance P can trigger migraine headaches in some individuals.

It is worth noting that not everyone who suffers from migraines will experience symptoms after consuming citrus fruits, and that triggers can vary greatly from person to person. If you experience migraines, it may be helpful to keep a food diary and track your symptoms to identify any patterns or triggers.


What Other Fruits Trigger Migraines?

Bananas – Bananas may cause migraines in some people due to their high potassium content. High levels of potassium can cause blood vessels to dilate, which triggers an attack.

Strawberries – Strawberries are another fruit that is thought to trigger migraines because of the amount of tyramine it contains. Tyramine is a chemical that affects blood vessels and causes them to dilate and constrict. When this happens, it can trigger a migraine attack.

Avocados – Avocado contains tyramine as well as other chemicals that may also trigger migraines in some people. The best way to determine if avocados are a trigger for you is by keeping track of what you eat and when your attacks occur. If you notice that eating avocados regularly results in a headache, then they may be the culprit behind your headaches or at least one possible trigger.

Grapes – Grapes contain similar compounds called pyrazines, which have been shown to cause headaches in some people.

Pineapples are rich in bromelain, an enzyme that breaks down protein but also activates serotonin receptors in the brain — these same receptors are activated during migraines, so eating pineapple could trigger one if you’re susceptible.

It is clear that citrus consumption is associated with an increased risk of developing headaches. While there are many potential explanations for this relationship, the most plausible explanation is that the high sugar content in citrus fruits increases blood sugar levels and causes inflammation in the brain.
