Nigiri Sushi Histamine Information

Eating Nigiri sushi, a prime delicacy consisting of sushi rice and typically topped with raw fish, may influence histamine levels in the body, predominantly based on the type of fish used and its freshness. Certain fish products, particularly aged, smoked or canned fish, are known to contain high levels of histamine (1). Tuna, a common type of nigiri sushi, for instance, is reported to have high amounts of naturally-occurring histamine due to its bacterial and enzymatic activity if not freshly served (2). Additionally, mackerel, another potential top ingredient in nigiri sushi, is also classified as a high-histamine food product (1). Additives used in the preparation of the rice might also have an influence. Some preservatives and food additives are known as histamine liberators which, while not containing histamine themselves, can stimulate its release within the body (3). However, not all fish used in Nigiri sushi contain high levels of histamine and, as such, some types of Nigiri sushi may not significantly influence histamine in the body. This also depends greatly on freshness and storage conditions of the fish used. On the other hand, ginger, usually served with sushi, appears to lower histamine levels due to its anti-inflammatory properties (4), potentially offsetting the histamine from the fish. In conclusion, the impact of eating Nigiri sushi on histamine levels will significantly depend on the type of fish used, its freshness, and the additives used in preparation. References: 1.
