Oysters Histamine Information

Oysters, as part of the invertebrate seafood category, are recognized as potential histamine liberators. They are not known to contain high levels of histamine themselves, but consumption could promote the release of histamine within the body. It is important to note that this could vary from person to person and may not affect everyone who has a sensitivity or intolerance to histamine the same way (1). Specifically, oysters are mentioned in a study by Maiwald, Herrmann, Murzabekova, and Pichler (2006), which lists them among other shellfish as potential histamine liberators (2). However, further research in this area is needed to fully comprehend the extent of their histamine liberating properties and the potential impact on individuals with histamine intolerance. On the other hand, it should be clarified that there is no concrete, research-based evidence yet to suggest that oysters themselves could help to lower histamine levels in the body. Further, the method in which the oysters are prepared could also play a role in their potential release of histamine. Freshly cooked or raw oysters are less likely to promote histamine release than smoked, fermented, or heavily preserved oysters. In the absence of concrete, science-based data, it is prudent to state: "This product has not been researched well enough to publish definitive information. Our team is working hard on this. Data will be available soon." References: 1. Jarisch, R. (2014). Histamine intolerance in clinical practice. Falzeben 225: 39010 Avelengo (BZ), Italy: Life Quality Improvement. 2.
