Zest Of Citrus Fruits Histamine Information

The zest of citrus fruits has various impacts on histamine levels due to its properties and components. The zest contains high amounts of bioflavonoids, such as hesperidin and quercetin. While these bioflavonoids do not necessarily contain histamine, they can influence histamine activity. Quercetin, in particular, is known for its anti-inflammatory and antioxidant effects and is often used as a natural antihistamine. It works by stabilizing mast cells and preventing them from releasing histamine. Therefore, the consumption of citrus zest might not directly lower histamine levels, but it might help control histamine release and thus alleviate symptoms of histamine intolerance (1). However, it should be noted that citrus fruits, including their zest, could act as histamine liberators in some individuals. A histamine liberator prompts the body to produce or release more histamine, thus potentially exacerbating symptoms in those with histamine intolerance (2). Therefore, while citrus zest can have beneficial effects due to its potential to stabilize mast cell and control histamine release, it might also cause an adverse reaction in some individuals. As individual responses can significantly vary, it is advisable for people with suspected histamine intolerance to individually test their response to citrus zest. References: 1. Maintz L, Novak N.
