English Breakfast Tea Histamine Information

English Breakfast Tea is a blend of several black teas, typically including Assam, Ceylon, and Kenyan teas. It is noted for its robust flavor profile and stimulating effects, which are predominantly due to the caffeine content. However, when assessing its impact on histamine levels, we must consider another compound found in tea: theophylline. Theophylline is a compound widely found in tea, including black tea, the primary component of English Breakfast Tea. Research shows theophylline has anti-inflammatory effects and it may assist in lowering histamine levels or suppressing its release, as outlined in a study published in the Journal of Allergy and Clinical Immunology (1). Nonetheless, it's important to note that the amount of theophylline in tea is considerably less compared to other sources such as medication. Furthermore, according to a study published in The American Journal of Clinical Nutrition, green and black teas (which encompass the teas used in English Breakfast Tea) can hinder the enzyme diamine oxidase (DAO), which is pivotal in the breakdown of histamine (2). This means that although the theophylline in black tea potentially suppresses histamine release, the tea itself could potentially delay the breakdown of histamine. It should also be noted that black tea, including English Breakfast, is a histamine liberator that promotes the release of histamine (3). Considering these conflicting roles in histamine production and release, more research is required to fully understand the specific impact of English Breakfast Tea on histamine levels. Consequently, individuals with a histamine intolerance or sensitivity may need to consider personal experience and medical advice when deciding on consumption. References: 1. Dean BB, Kaplan AP.
