The histamine, is a compound that is found in all cells of the body and, in addition, is a natural component present in many foods, which we consume daily. This substance is an important part of both the immune system and the neurological system. Deficiency, abundance or allergy to this compound can cause various problems to the body.
In a person without any health inconvenience, histamine is regularly broken down with the help of 2 enzymes: DAO and HNMT.
For this reason, those individuals who have difficulties with histamine, it is because they have a genetic dysfunction or a greater presence of one of these 2 enzymes.
For these cases, it is essential to know the list of foods with histamine, so as not to have health problems.

Causes of histamine allergy
The DAO enzyme is produced in the gut, so if bowel function is in trouble, there may not be enough enzymes to break down histamine normally.
Precisely, people allergic to this component, have an important imbalance, between different populations of bacteria in their intestine.
In turn, the habit of smoking, is another of the most common causes of those patients, who have this type of rejection towards the compound.
Keep in mind that allergies are very specific discomforts and their causes can be multiple. So you can be in very good health and still have problems digesting food, with a high content of histamine.
Symptoms of histamine intolerance
When a person has problems or intolerance towards this component, which is so important for the body, the symptoms can be diverse.
Some are very common discomforts, which can be perfectly confused with other diseases.
Whatever the case, it is important to go to a trusted doctor, who will surely detect where the problem is.
Among the symptoms that we could call “less serious” and that can perfectly lend themselves to confusion, we find:
- Runny nose (excessive perspiration in this area).
- Watery eyes.
- Itchy skin.
Depending on the level of rejection of histamine, the body may have more important discomforts, such as:
- Low blood pressure.
- Rash, with large welts on the body.
- Angioedema (swelling of the face).
- Wheezing (trouble breathing).
In addition, in the case of women, during the menstrual cycle, may suffer severe headaches or deep cramps, due to the contractions produced by histamine, in relation to low hormone levels.

How histamine allergy is diagnosed
At present, there are no proven tests, which can diagnose histamine intolerance, beyond the feeding diet.
Although it is possible to measure the activity of the DAO enzyme in the blood, as well as the levels of this component in the blood and urine, but these results cannot be correlated, yet, with the symptoms of histamine allergy.
For this reason, a healthy diet is, for the moment, the only solution to this type of disorder. In general, the patient has a follow-up by his doctor and if, after several weeks, the histamine levels are correct, it means that the diet is working.
