Difference between Food Allergy and Histamine Intolerance
While the symptoms of Histamine Intolerance (HIT) may mimic allergic reactions, histamine intolerance is not a classical food allergy.
Rather, research suggests that histamine intolerance is mediated by a deficiency in levels and/or activity of the Diamine Oxidase enzyme.
Symptoms of Histamine Intolerance
- Vasodilation (flushing/reddening)
- Stuffy, Runny Nose/Sneezing
- Swelling or red, watery eyes
- Headache or Migraine
- Diarrhea, cramps, bloating
- Feelings of anxiety
- Urticaria (hives)
