Oregano Pesto Histamine Information

Oregano Pesto is a culinary delicacy primarily made from fresh oregano leaves, garlic, pine nuts, Parmesan cheese, and olive oil. Based upon the ingredients and their relationship with histamine, it can be inferred that this dish might inherently contain certain implications for those concerned with histamine levels. Oregano is believed to exhibit antihistamine properties that aid in reducing the body's histamine levels. It's packed with compounds like rosmarinic acid and thymol that could potentially inhibit the activity of histamine-producing cells (1). Hence, it could be useful in managing histamine levels. Garlic, although not significant in histamine content, is renowned for its immunity-boosting attributes and has been reported to suppress histamine release from mast cells (2). Olive oil is primarily composed of monosaturated fats and is typically not associated with raising histamine levels. Parmesan cheese and pine nuts, however, raise some concerns. Parmesan cheese, being a mature cheese, is potentially high in histamine content (3). Pine nuts also, under certain conditions, could be a histamine liberator, causing the release of stored histamine in the body (4). In conclusion, despite having ingredients that may affect histamine levels, the antihistamine properties of oregano could potentially counterbalance the effects of other ingredients. However, each individual may react differently, so it's advisable to consume with caution if you have a known histamine intolerance. Unless otherwise specified, the impact of Oregano Pesto on histamine levels would vary based on the individual’s unique reaction and the serving size consumed. References: 1.
