Candied Nuts Histamine Information

Candied nuts, due to their elevated sugar content, can have a significant impact on histamine levels, much in the manner of other high-sugar foods and drinks. While nuts, as an edible category, are not high in histamine, they have been found to be histamine liberators and, in some cases, can delay the breakdown of histamine. For instance, walnuts and hazelnuts are known histamine liberators, which mean they can stimulate the release of histamine in the body (1). Additionally, the nature of candied nuts, frequently roasted before being candied, may further amplify this impact. Research indicates that cooking methods can change the histamine content in food, with roasting potentially contributing to higher levels (2). However, it's worth noting that not all nuts have the same influence. For instance, cashews and pistachios are evaluated to have lower histamine content (3). In conclusion, while the exact impact of candied nuts on histamine levels may vary depending on the type of nut and other factors like preparation method, there is potential for them to increase histamine in the body due to their properties as histamine liberators and potential delay of histamine breakdown.
