Omelets Histamine Information

Eating omelets can have varying impacts on histamine levels based on the ingredients used. Eggs by themselves are not known to be high in histamine or to significantly affect histamine levels. However, research on egg intolerance shows that egg white proteins can act as histamine releasers in some individuals. The yolk, on the other hand, is often better tolerated (1). Cheddar cheese, a common addition to omelets, is a hard cheese and long-ripened, therefore it's high in histamine content (2). Other dairy products such as milk or cream added to omelets are generally low in histamine. Vegetables such as tomatoes and mushrooms, often used in omelets, have a high histamine content and mushrooms also act as histamine liberators (3). Smoked meats like ham and salami are frequently used in omelets and are high in histamine (3). The cooking time can also influence the histamine content. Research shows that histamine levels in food increase when cooked over a long period (4). In terms of ingredients that can lower histamine levels, there's not much scientific material available. However, some specialists suggest that fresh ingredients, as opposed to processed or fermented foods, tend to be lower in histamine (5). Thus, the impact of an omelet on histamine levels is highly dependent on the specific ingredients used. The combination of ingredients, as well as their preparation and freshness, can affect the final histamine content of the omelet. References: 1.
