If you are experiencing any of these situations, then you might be experiencing a histamine attack on your immune system.
During an allergic response, the body’s immune system starts to react by releasing various immune compounds to protect itself from foreign substances that identify as harmful. One of these immune compounds, known as histamine, is commonly present in a variety of foods. When histamine is elevated in the body, it is due to a high dietary intake or an inability to break it down, so individuals may experience allergic symptoms from a histamine reaction.
Histamine is a compound that is formed through the metabolism of specific amino acids in the immune system. There are a variety of levels of histamine that is found naturally in the foods that people consume. It is also produced by the body where it is in specific immune cells, including mast cells and basophils. During an allergic and other immune response, histamine is released from these cells, and consuming large quantities of histamine that is over 100 mg may result in a mild adverse reaction. Studies have shown that if histamine is consumed in a higher amount that is over 1000 mg, it can lead to histamine intoxication or histamine poisoning.
Under normal conditions, histamine is released in the body or ingested through food, and it is broken down by two enzymes: HNMT (histamine-N-methyltransferase) and DAO (diamine oxidase). High levels of histamine can occur in individuals that have reduced activity of these enzymes. When histamine levels are increased, or the ability to break down histamine is impaired, individuals may experience histamine intolerance, which will generally present itself as an allergic reaction to the immune system.
Specific individuals may have an increased sensitivity to biogenic amines like histamine. Some factors have been associated with an increased risk of histamine intolerance, including:
Mast cell conditions can increase the secretion of histamine. Since mast cells are found throughout the body, they are involved with the innate immune response as well as being the primary source of histamine in the intestines. Studies show that when specific immune receptors detect a foreign substance in the body, the mast cells secrete inflammatory compounds like histamine as a protective response. Mast cell activation is characterized by increasing plasma and urine histamine levels as well as an increased histamine metabolite in the urine. Several conditions are associated with mast cell activation, including:
With histamine intolerance symptoms being presented as an allergic response, some of the signs and symptoms include:
With dietary support for histamine intolerance, it may involve a histamine-free diet. Studies have been examining the effects of four-week histamine-free diet intervention on 22 individuals that have CU (chronic urticaria). Chronic urticaria is a common skin condition that is characterized by episodes of red marks and swelling that last longer than six weeks on the body.
A study found that when it is being compared to baseline, plasma histamine levels were significantly reduced when following the diet. Additionally, USS (urticaria severity score) and (UAS), both decreased following the intervention. It means that a histamine-free diet may help improve symptoms that are associated with dietary histamine intake or histamine intolerance like chronic urticaria in the body.
Research also shows that when individuals follow a histamine-reduced diet, it may increase the levels of the DAO enzyme. Research also demonstrated that when individuals followed the histamine-reduced diet for an average of 13 months, the increased levels of DAO were correlated with the degree of compliance to the diet. When high-histamine and histamine-liberated foods are eliminated, the individual’s tolerance levels can be determined by slowly reintroducing foods to test for potential reactions.
Certain foods may increase histamine levels by providing a dietary source or by liberating histamine in the body. Studies have found that it is essential to note that inconsistent levels of histamine are found in various foods and that the levels may fluctuate based on the maturity, storage, and processing of the food.
Here are the high-histamine foods to avoid on a histamine-free diet. They are:
Here are the histamine-liberating foods to avoid on a histamine-free diet as well. They are:
With methods surrounding food preparations that should be considered, researchers have suggested that people should consume food that is fresh as possible and boiled rather than frying or grilling food may help reduce the intake of biogenic amines like histamine. Studies have shown that spoiled foods have been found to have high levels of histamine, so it is essential to be mindful when consuming leftovers, especially leftover fish. There are some individuals with histamine intolerance that may benefit from taking antihistamine medication or a DAO supplement. There are also certain nutrients, including copper, vitamin B6, and vitamin C that can help support histamine degradation.
When the body is suffering from an allergic response, its’ immune system starts to react by sending out various immune compounds that attack harmful foreign substances. Histamine is one of the immune compounds that is produced and broken down to HNMT and DAO. Histamine can also trigger an asthma attack on individuals, while certain foods can contain high-histamine and histamine-liberating properties that can be harmful in the body. Some products use an advanced formula that helps support the immune system, targets amino acids, and supports antioxidant processes to make sure that the body is functioning correctly.
