Tyramine-Rich Foods: Comprehensive Guide, Risks, and Low-Tyramine Choices
Balancing meal choices helps prevent migraine attacks and maintain healthy blood pressure.
Tyramine and Its Role in Food and Health
Tyramine is a naturally occurring compound found in a variety of animal and plant foods. It forms when the amino acid tyrosine is broken down, a process facilitated by aging, fermentation, and spoilage. While most people can process tyramine without issue, for certain individuals—particularly those taking monoamine oxidase inhibitors (MAOIs) or people prone to migraines—tyramine consumption can pose health risks ranging from headaches to hypertensive crises.
What is Tyramine?
Tyramine is a type of monoamine compound. Structurally similar to adrenaline and noradrenaline, it can significantly affect blood pressure and neurological activity. The body uses the enzyme monoamine oxidase (MAO) to break tyramine down. In people with reduced MAO activity—either naturally or due to medication—tyramine accumulates, potentially causing adverse reactions.
Why Does Tyramine Matter?
For most, tyramine causes no problems. However, it can trigger serious effects in those who:
- Take MAOI medications for depression, Parkinson’s, or other conditions.
- Suffer from frequent migraines.
- Have a sensitivity to certain food compounds.
Excessive tyramine causes nerves to release norepinephrine, raising blood pressure and sometimes provoking migraine attacks.
Potential Health Effects of High Tyramine Intake
- Migraine headaches: Tyramine is a recognized trigger for migraines in susceptible people.
- Hypertensive crisis: Especially in those taking MAOIs, high tyramine can cause a rapid, dangerous increase in blood pressure. Symptoms may include:
- Severe headache
- Nausea
- Chest pain
- Shortness of breath
- Rapid heart rate
- Sweating
- Other symptoms: Possible anxiety, palpitations, or sweating even without a hypertensive episode.
Anyone experiencing these symptoms—especially when on MAOI drugs—should seek immediate medical attention.
How Tyramine Levels Increase in Food
Tyramine concentrations rise during the aging, fermentation, cure, or spoilage of foods. Microbes involved in these processes convert the amino acid tyrosine to tyramine, making certain food categories riskier than others.
Foods High in Tyramine
Here are some major food categories that are typically high in tyramine. Avoid or limit these if you are sensitive, have migraines, or take MAOIs:
| Food Category | Common Examples | Reason for High Tyramine |
|---|---|---|
| Aged Cheeses | Cheddar, Parmesan, Roquefort, Blue, Swiss, Camembert, Feta | Aging process increases tyramine levels |
| Cured & Processed Meats | Salami, Pepperoni, Hot dogs, Bologna, Bacon, Smoked fish | Curing and fermentation enhance tyramine |
| Fermented or Pickled Vegetables | Sauerkraut, Kimchi, Pickled beets/cucumbers/peppers | Microbial fermentation produces tyramine |
| Alcoholic Beverages | Beer, Red wine, Vermouth, Sherry, Some liqueurs | Fermented alcohol content |
| Citrus & Tropical Fruits (Overripe) | Ripe bananas, Pineapples, Avocado, Oranges, Grapefruit, Lemons, Limes, Tangerines | Ripening and storage increase tyramine |
| Fermented Soy Products | Miso, Tofu, Tempeh, Soy sauce | Fermentation process |
| Other | Chocolate, Certain nuts, Sourdough bread | Fermentation or aging |
Primary Foods High in Tyramine
- Aged cheeses (e.g., cheddar, blue, swiss, parmesan, Camembert)
- Cured or processed meats (e.g., salami, pepperoni, hot dogs, bacon, smoked fish)
- Fermented, pickled, or aged vegetables (e.g., sauerkraut, kimchi, pickled products)
- Alcoholic drinks (mostly beer, red wine, certain liqueurs)
- Some fresh produce when overripe (e.g., bananas, avocados, certain citrus, tropical fruits)
- Fermented soy products (tofu, miso, tempeh, soy sauce)
- Chocolate and some nuts

Who Should Avoid Tyramine-Rich Foods?
The following groups are strongly advised to limit tyramine:
- People taking MAOI medications: This class of antidepressants (and certain Parkinson’s drugs) blocks the enzyme that breaks down tyramine, substantially increasing the risk of hypertensive crises.
- Frequent migraine sufferers: Many find that tyramine is a migraine trigger.
- Individuals with demonstrated tyramine sensitivity: If you experience symptoms after consuming tyramine-rich foods, consult a healthcare professional.
Symptoms of a Hypertensive Crisis
A hypertensive crisis is a medical emergency. Key symptoms include:
- Sudden, severe headache
- Severe chest pain
- Nausea or vomiting
- Blurred vision
- Shortness of breath
- Confusion
- Rapid or irregular heartbeat
If you or someone else experiences these symptoms and has a known risk (such as being on an MAOI), seek emergency medical attention immediately.
Low-Tyramine Foods: Safe Choices
Following a low-tyramine diet is not about deprivation—many foods are naturally low in tyramine and safe to eat even for those at risk.
Foods Typically Safe and Low in Tyramine
- Fresh, unfrozen meats and poultry (use within 24–48 hours and avoid aging)
- Fresh fish (not smoked or pickled)
- Dairy products: Cream cheese, ricotta, cottage cheese, and low-fat processed cheese
- Eggs
- All grains: Cereals, bread (unleavened, with baking powder, or fresh yeast—but not sourdough)
- Most fresh vegetables (e.g., spinach, pumpkin, carrots, squash, asparagus, potatoes, soybeans, cooked onions, navy beans)
- Most fruits: Apples, cherries, peaches, apricots (in moderation and if not overripe or dried)
- Fruit juices (freshly prepared)
- Decaffeinated or weak coffee
- All oils and commercial salad dressings
- Commercially prepared yeast
It’s generally best to consume fresh prepared food rather than leftovers for those highly sensitive to tyramine.
Foods to Limit or Eat With Caution
Some foods are low or moderate in tyramine if consumed in small amounts or if very fresh. The following should be consumed sparingly:
- Hot dogs, bacon, lunch meat, or sausages with nitrates (check labels and limit frequency)
- Less than half a cup daily of citrus fruit or pineapple
- Chocolate products and puddings
- Wine vinegar or other fermented vinegars (use in tiny quantities)
- Small amounts of yogurt, buttermilk, or sour cream
- Homemade yeast-leavened bread/cake (avoid if sour or aged)
- Raw onion, avocados, bananas, passion fruit, papaya, figs, raisins, dried fruit, red plums (limit to small amounts if no reaction)
- Canned soups with yeast extracts or MSG
- Sourdough bread
Always consult your doctor for personalized guidance, particularly if you are on MAOIs or have other medical concerns.
Tips to Reduce Tyramine Intake
- Choose fresh foods and eat them soon after purchase.
- Avoid aged, fermented, or pickled products as much as possible.
- Keep leftovers refrigerated promptly, and avoid consuming them after 24–48 hours.
- Check food labels for terms such as “aged,” “smoked,” “fermented,” or “cured.”
- When dining out, ask about the preparation methods—avoid dishes using aged cheeses, pickled vegetables, or processed meats.
- Stay hydrated, and keep a food diary to track potential tyramine reactions.
Table: Foods High vs. Low in Tyramine
| High Tyramine Foods | Low Tyramine Foods |
|---|---|
| Aged cheeses | Cream cheese, ricotta, cottage cheese |
| Salami, pepperoni, smoked fish | Fresh meat, poultry, fish (not aged, smoked, or pickled) |
| Sauerkraut, pickled vegetables | Most fresh vegetables |
| Beer, red wine, sherry | Fruit juice, decaf coffee, club soda |
| Miso, soy sauce, tempeh | Commercially prepared yeast, pasta, grains |
| Ripe bananas, avocados, pineapple | Apples, peaches, apricots (fresh, not dried/overripe) |
Consulting a Healthcare Professional
If you believe you’re having adverse reactions to tyramine-rich foods, or if you are about to start or are already taking an MAOI medication, always consult your physician. A healthcare professional can:
- Confirm whether a low tyramine diet is appropriate for you
- Provide an individualized food list and recommendations
- Guide you in managing medications and dietary restrictions
