Chicken Stock Histamine Information

Chicken stock, traditionally crafted from chicken bones, vegetables, and spices, can have varying impacts on histamine levels based on its preparation method and ingredients used. Histamine is naturally present in many foods and is also released in our bodies. It is typically broken down by specific enzymes; diamine oxidase (DAO) and histamine N-methyltransferase. Problems can occur when there's an imbalance between histamine intake and degradation, which may manifest in the form of histamine intolerance symptoms. As far as chicken stock is concerned, its histamine content largely depends on how long the bones are cooked. Simmering chicken bones for longer durations (such as in bone broth) can potentially lead to higher histamine levels in the final product. This is because histamine is formed during the cooking process of high-protein foods like chicken (1). Hence, if one is concerned about histamine levels, it would be beneficial to use stocks that are cooked for shorter periods of time or choosing pre-made low-histamine certified products if available. In the case of chicken stock, some ingredients that might be added, such as tomatoes and vinegar, contain high levels of histamine (2). On the other hand, if ingredients such as black or green tea, cocoa products, or certain fruits are used, they could potentially slow down the breakdown of histamine in the body or even liberate more histamine (2)(3). However, it is also important to note that not all ingredients or foods listed as high in histamine, histamine liberators, or DAO blockers will affect all individuals in the same way. Personal tolerance levels can vary greatly. That being said, there is limited research specifically pertaining to chicken stock and its impact on histamine levels, hence concrete statements cannot be made regarding the same. References: 1.
