The Primary Suspects: Tyramine and Histamine
The most common culprits found in cheese that are linked to migraines are two types of biogenic amines: tyramine and histamine. These compounds form naturally when bacteria break down amino acids as part of the aging and fermentation process. The longer a cheese is aged, the higher the concentration of these amines tends to be.
The Role of Tyramine
Tyramine is a natural amino acid that helps regulate blood pressure in the body. Normally, an enzyme called monoamine oxidase (MAO) breaks down excess tyramine. However, in some individuals, particularly those with migraine, there may be a reduced ability to process this compound. When tyramine levels increase, it can lead to a rise in blood pressure and the constriction and subsequent dilation of blood vessels, which can trigger a migraine headache. For individuals taking certain antidepressants known as MAO inhibitors, the risk of a reaction is significantly higher due to the blocking of the MAO enzyme.
The Impact of Histamine
Like tyramine, histamine is a biogenic amine found in aged and fermented foods, including many cheeses. Histamine plays a crucial role in the immune system, but in excess, it can cause problems. In sensitive individuals, high dietary histamine can lower the migraine threshold, making them more vulnerable to an attack from any trigger. Some people also have a condition called histamine intolerance, caused by a deficiency in the enzyme diamine oxidase (DAO), which is responsible for breaking down histamine. When this enzyme is lacking, histamine can build up in the body and trigger various symptoms, including migraines.
Beyond Tyramine and Histamine: Other Factors
While tyramine and histamine are the most studied culprits, other components of cheese can also play a role in triggering migraines for some individuals.
Dairy Protein and Lactose Sensitivity
Some migraine sufferers may have a sensitivity to dairy proteins (like casein) or suffer from lactose intolerance. In these cases, consuming dairy can trigger an inflammatory response within the body. Neuroinflammation is known to play a role in migraine pathophysiology, and this systemic inflammation can potentially exacerbate or induce a migraine attack. Symptoms of lactose intolerance, such as gut discomfort and bloating, are sometimes confused with or can co-exist with migraine attacks, making it difficult to pinpoint the exact trigger.
Food Additives
Highly processed cheeses, and other dairy products like whipped cream and some sauces, may contain additives and preservatives that can act as triggers. These can include emulsifying salts, carrageenan, and monosodium glutamate (MSG), which may impact headache frequency in sensitive individuals.
Cheeses to Watch and Safer Alternatives
Identifying which cheeses contain high levels of tyramine and histamine is an important step in managing your triggers. Aged cheeses are generally higher in these compounds, while fresh varieties contain lower levels.
High-Risk Cheeses
- Aged Cheddar: A popular and well-aged cheese with high tyramine levels.
- Blue Cheese: Includes varieties like Gorgonzola and Stilton, which are known to be significant triggers.
- Parmesan: This hard, aged cheese is often implicated due to its high tyramine content.
- Swiss: Both Swiss and other hard, aged cheeses can be problematic for sensitive individuals.
- Feta: While not as hard as Parmesan, this brined and aged cheese can also contain high levels of amines.
Lower-Risk Cheeses
- Fresh Mozzarella: Made from fresh milk, this cheese has a low tyramine count.
- Ricotta: A soft cheese made from whey that is not aged.
- Cottage Cheese: A fresh cheese with a low tyramine content that is generally considered safe.
- American Cheese: Processed American cheese, made with pasteurized milk, typically has lower tyramine.
- Cream Cheese: A fresh, soft cheese that is generally tolerated well.
Comparison of Aged vs. Fresh Cheese Triggers
| Feature | Aged Cheeses (e.g., Blue, Parmesan) | Fresh Cheeses (e.g., Mozzarella, Ricotta) |
|---|---|---|
| Tyramine/Histamine Content | High, due to extended protein breakdown during aging. | Low, as they are not aged and are consumed fresh. |
| Aging Process | Fermented and aged for a significant period. | Unfermented or minimally fermented, and not aged. |
| Migraine Risk | Higher, especially for individuals sensitive to biogenic amines. | Lower, and often tolerated by those with food triggers. |
| Associated Factors | Can be higher in fat content, which may also contribute to inflammation. | Typically lower in fat and free from common fermentation byproducts. |
Managing Your Migraine Triggers
The connection between food and migraines is highly individual. While aged cheese is a common trigger, it does not affect all migraine sufferers universally. The most effective strategy for identifying your personal food triggers is to keep a detailed headache diary.
How to use a headache diary:
- Track Food Intake: For each meal, jot down what you ate, paying special attention to potential trigger foods like aged cheese.
- Record Symptoms: Log the time, severity, and duration of any migraine episodes, along with associated symptoms like nausea or aura.
- Note Other Factors: Include information about sleep patterns, stress levels, and other potential non-food triggers to see if they coincide with your dietary intake.
- Elimination Diet (with medical guidance): If a pattern emerges, consider an elimination diet, under the supervision of a healthcare professional or registered dietitian. This involves removing a suspected food for a period of time to see if symptoms improve.
By carefully monitoring your diet and symptoms, you can identify if cheese is a trigger for you and, if so, which types are most likely to cause an issue. While avoiding aged cheeses is a common strategy, some individuals may find they have broader dairy sensitivities.

Conclusion
The link between cheese and migraines is complex and primarily associated with biogenic amines like tyramine and histamine, which are concentrated in aged and fermented varieties. However, other factors, including general dairy sensitivity, lactose intolerance, and food additives in processed cheeses, can also contribute to triggering a migraine attack. The sensitivity to these compounds varies widely among individuals, emphasizing the importance of personalized management strategies. Keeping a food and headache diary is the most effective way to identify your specific triggers. By understanding the potential mechanisms behind why cheese affects some people, migraine sufferers can make more informed dietary choices to help manage their condition and reduce the frequency of attacks.
