Tyramine Free Diets

What is tyramine?


  1. Tyramine is naturally present in some foods.
  2. Most people consume tyramine without experiencing any negative effects.
  3. Tyramine-rich foods might interact with or alter how medications work in your body.

If you experience migraines or take monoamine oxidase inhibitors (MAOIs), you may have heard of a tyramine-free diet. Tyramine is a compound produced by the breakdown of an amino acid called tyrosine. It’s naturally present in some foods, plants, and animals.

What does tyramine do?

Your adrenal glands generally respond to tyramine by sending catecholamine, or the fight-or-flight hormone, into the bloodstream along with three other hormones:

  • dopamine
  • norepinephrine
  • epinephrine

This gives you a boost of energy and, in turn, elevates your blood pressure and heart rate.

Most people consume tyramine without experiencing any negative side effects. However, the release of this hormone can cause life-threatening blood pressure spikes, especially when consumed in excessive amounts.

When should I consider a tyramine-free diet?

Tyramine-rich foods might interact with or alter how medications work in your body. For example, certain MAOIs, including certain antidepressants and medications for Parkinson’s disease, can cause tyramine buildup.

Excessive tyramine intake may lead to a hypertensive crisis that can be fatal, according to the Mayo Clinic. A hypertensive crisis can occur when blood pressure is so high that you have a greater chance of stroke or death.

If you have a poor ability to break down amines such as tyramine or histamine, you may experience allergic-type reactions to small amounts of amines. Your doctor may say that you’re “amine intolerant.”

For the majority of people who are amine intolerant, tyramine’s effects are most obvious when you have excessive amounts. At high enough levels, you might experience symptoms, such as:

  • heart palpitations
  • nausea
  • vomiting
  • headaches

If you think you may be sensitive to tyramine or if you’re taking MAOIs, report any symptoms to your doctor.

As a treatment for migraines, some doctors recommend trying a low-tyramine or tyramine-free diet, such as the ones provided by Northwestern Memorial Hospital’s Health Learning Centers. The diet’s effectiveness for treating migraines isn’t medically proven.

What foods are high and low in tyramine?

If you’re sensitive to tyramine or you’re taking MAOIs, you may want to limit your intake of tyramine-rich foods and beverages to lower your chances for tyramine buildup.

High-tyramine foods

Certain foods have high amounts of tyramine, especially foods that are processed and:

  • fermented
  • cured
  • aged
  • spoiled

Specific foods with high tyramine content include:

  • cheeses
  • aged meats
  • tap beers
  • dry sausages
  • salamis
  • aged chicken livers
  • pickled or smoked fish
  • soy products
  • bouillon
  • sauerkraut
  • miso soup
  • pineapples
  • chocolate
  • sourdough breads
  • fresh or homemade yeast

Moderate-tyramine foods

Food list for low-tyramine diets
These foods have either no tyramine or very low amounts of it:
  • fruits, including raisins
  • vegetables
  • ketchup
  • mustard
  • coffee
  • Worcestershire sauce
  • soft drinks
  • cream cheese
  • butter
  • peanut butter
  • potatoes

Fresh, frozen and, canned meats, including poultry and fish, are acceptable for low-tyramine diets:

Tips for limiting tyramine intake

If you want to limit your tyramine intake, follow these guidelines:

  • Use extra caution when selecting, storing, and preparing your food.
  • Eat fresh produce within two days of purchase.
  • Read all food and drink labels carefully.
  • Avoid spoiled, aged, fermented, or pickled foods.
  • Don’t thaw foods at room temperature. Thaw in the refrigerator or the microwave instead.
  • Eat canned or frozen foods, including produce, meats, poultry, and fish, right after opening.
  • Buy fresh meats, poultry, and fish and eat them the same day, or freeze them immediately.
  • Keep in mind that cooking will not lower tyramine content.
  • Use caution when you eat out because you don’t know how foods have been stored.

The takeaway

Tyramine buildup in the body has been associated with migraines and life-threatening blood pressure spikes in people taking MAOI antidepressants. If you experience migraines, think you may be intolerant to amines, or take MAOIs, you may want to consider a low-tyramine or tyramine-free diet. Talk to your doctor first, and ask them if this diet will work well with your ongoing medical treatment.
