Lemon Tart Histamine Information

Lemon tart, a popular dessert, is typically made of butter, sugar, flour, eggs, and, of course, lemon. Essential ingredients could lie in all three categories: high histamine, histamine liberators, and substances that delay histamine breakdown. For instance, both butter and eggs contain low levels of histamine but are known to function as histamine liberators (1)(2). Despite their low histamine content, they could trigger the release of stored histamine in the body, potentially leading to symptoms in individuals with histamine intolerance. Furthermore, lemon, the main flavoring agent in a lemon tart, is a citrus fruit and falls under the category of histamine liberators (3). Therefore, ingestion of a lemon tart could provoke histamine release. Flour is generally neutral in terms of histamine content and histamine release activity (4). Sugar is likewise neutral, although some sources suggest avoiding large quantities of sugar when one has histamine intolerance due to its potential impact on gut health (5). In absence of clear evidence suggesting the impact of eating a lemon tart on histamine levels, one should take into account the individual ingredients and their potential effects on histamine levels. If a person with histamine intolerance experiences an adverse reaction after consuming a lemon tart, it could potentially be due to the combination of multiple ingredient's histamine liberating properties. However, more concrete research is needed to provide a definitive answer. Consequently, this product has not been researched well enough to publish any information, our team is working hard on this. Data will be available soon. References: 1. Maintz L, Novak N. Histamine and histamine intolerance. Am J Clin Nutr. 2007 May;85(5):1185-96. 2. Joneja JM.
