What are Histamine Intolerance Symptoms?

Histamine Intolerance Symptoms Explained

Histamine intolerance is defined as a complete or partial inability to process histamine - a chemical substance that naturally occurs in several kinds of food, and is also released by the organism during an allergic reaction. Histamine intolerance happens because in some cases our organism does not produce enough of diamine oxidase, an enzyme that plays a key role in decomposing histamine. When a person with histamine intolerance ingests histamine foods or products that stimulate the production of histamine in the body, he or she will most likely experience several allergy-like symptoms.

Histamine intolerance symptoms often include:

  • Low blood pressure;
  • Runny or stuffy nose;
  • Itching, redness hives;
  • Cough, often persistent;
  • Headache or migraines;
  • Heart rhythm problems, flushing;
  • Stomach acid reflux;
  • Nausea, vomiting, diarrhea;
  • Tiredness, body ache.

Recommended Histamine Intolerance Diet

The idea behind a histamine intolerance diet is to determine if your organism cannot process this substance well enough. By reducing the amount of histamine-rich foods in your ration, you should notice a significant improvement in your symptoms. If the improvement does not occur, this means something else is causing your symptoms, most likely an allergy you are not yet aware of. However if you do feel better, you should try and add one or several of histamine foods to make sure you have histamine intolerance. If your symptoms return, you should contact a professional dietitian to compose a healthy diet low on histamine. Leading a wholesome self-organized histamine-free diet is almost impossible as you will most likely come under a risk of suffering from malnutrition and digestive problems.

Foods that are particularly high in histamine include:

  • Fermented alcoholic drinks and spirits (beer, cider, champagne, wine, and others);
  • Vinegar, including foods containing it (ketchup, mayonnaise, salad dressings, mustard, pickled products);
  • Cheese (Camembert, brie, cheddar, Parmesan, Swiss cheese, and blue cheese);
  • Fish (tuna, mackerel, sardines, salmon, herring);
  • Processed meat products (sausages, salami, bacon, ham);
  • Dried fruit, seeds and nuts;
  • Cocoa and cocoa products (chocolate);
  • Soy sauce;
  • Mushrooms.
