What Is Tyramine?
Tyramine is found in many foods, including wines, ripe cheeses, and fermented or aged foods.
Why Should I Follow a Low-Tyramine Diet?
A low-tyramine diet is recommended if you are taking monoamine oxidase inhibitors (MAOIs), a type of drug found in certain antidepressants, Parkinson’s medications, and antibiotics. Eating foods with high amounts of tyramine while taking MAOIs can cause a drug-nutrient interaction that produces side effects such as elevated blood pressure, headaches, heart palpitations, and chest pain.

- Limit caffeine intake. While there is no tyramine in caffeine, consuming too much caffeine can result in high blood pressure.
- Check ingredient lists for the presence of tyramine-containing ingredients, such as marmite and yeast-extracts.
- Fresh food is less likely to contain high levels of tyramine.
- Promptly refrigerate or freeze foods.
- Use or toss leftovers within 48 hours.
- Eat allowed fresh meats within three days.
- Eat allowed cheese within three to four weeks.
