Walnuts Histamine Information

Walnuts interact with histamine levels in a variety of ways; although they do not contain a high histamine content, they act as histamine liberators. Histamine liberators do not contain histamine themselves, but promote its release in the body. Thus, for individuals with histamine intolerance, consumption of walnuts may lead to excessive histamine response, resulting in symptoms such as itching, congestion, or headaches. While walnuts have this potential for triggering a histamine release, it's also important to consider that they, along with other nuts, may delay the breakdown of histamine. This process is known to increase histamine's duration of action in the body, which could potentially amplify any symptoms related to histamine intolerance. Conversely, some evidence suggests that walnuts might contain substances, specifically their Omega-3 fatty acids content, that might help in lowering histamine levels. Omega-3 fatty acids are known for their anti-inflammatory properties and have been shown to inhibit the release of inflammatory substances including histamine in the body. However, it is important to note that the impact of walnuts on histamine levels is dependent on individual responses and may vary from person to person. Those susceptible to histamine reactions should approach the consumption of walnuts with caution. References: 1. Maintz, L., & Novak, N. (2007). Histamine and histamine intolerance.
