It is advisable for individuals with histamine intolerance to adhere to a low-histamine diet. Although histamine is involved in numerous physiological processes, an overabundance of it can result in symptoms reminiscent of an allergic reaction. Food intolerances affect approximately 20% of the western populace, with histamine intolerance being among the most prevalent. This article will define histamine intolerance, discuss the benefits of a low-histamine diet, and list foods to avoid.
Histamine And Histamine Intolerance Are Related Terms
Histamine, a chemical entity secreted by mast cells (a subset of white blood cells), plays a regulatory role in the body's reaction to exogenous stimuli. To put it simply, the body secretes histamine in response to perceived threats. Although the body obtains a certain quantity of histamine from its own tissues, it can also be found in specific substances.
The World Health Organization and the Food and Health Organization of the United Nations both state that histamine-rich foods may induce histamine intolerance in individuals with heightened sensitivity and impaired histamine metabolism. Similar to an allergic reaction, the symptoms of histamine intolerance are:
-
Headaches
-
Palpitationi Redness
-
Skin inflammation
-
Nausea
-
Vomiting
-
Itchy epidermis
-
Rashes
-
Diarrhea
According to the American Academy of Allergy, Asthma, and Immunologyi , there is no specific test for diagnosing histamine intolerance. So, physicians select for an elimination diet. This means eliminating histamine-rich foods for 4 weeks and progressively bringing them back. This allows your doctor to determine which substance is inciting the symptoms.
Benefits Of A Low-Histamine Diet
May Lower The Level Of Histamine In Your Body
The primary purpose of a low-histamine diet is to decrease the level of histamine in the body. Diamine oxidase is an enzymei that is responsible for breaking down histamine in our bodies. Studies have suggested that reduced levels of diamine oxidase (DOA) may increase the levels of histamine in the body. In another study, patients with histamine intolerance had diminished DOA activity. The same patients when asked to go on a low-histamine diet with DOA supplements saw an improvement in the symptoms.
May Help Reduce The Symptoms Of Hives
A low-histamine diet may be instrumental in reducing the symptoms of hivesi . A study was conducted in 2018 to see the effect of a low-histamine diet on patients with chronic urticaria. The patients were prohibited from consuming histamine-rich cuisine for 4 weeks. After 4 weeks, the researchers discovered a significant decrease in the histamine levels and severity of hive symptoms. Research also suggests that consuming a low-histamine diet for 3 weeks may be beneficial to patients with urticaria accompanied by gastrointestinali symptoms.
May Help Manage Atopic Dermatitis
Similar to symptoms of histamine intolerance, the symptoms of atopic dermatitisi may worsen due to the consumption of histamine-rich food. A study conducted on a child with atopic dermatitis found that a low-histamine diet is instrumental in the diminution of symptoms.
Eating a low histamine diet may reduce the symptoms of IBS. Research suggests that avoiding gluten-rich foods and fermented products may play an essential role in reducing the symptoms of IBS.

Factors such as storage time, addition of preservatives, and how ancient the product is can impact its histamine levels. Make sure you avoid foods labeled as “histamine liberators” as they are meant to help release histamine from other foods you consume. Here is a list of substances that may have elevated levels of histamine:
-
Cheese, sour cream, buttermilk, and yogurt
