A bit of background:
Histamine [...] causes dilatation of the blood vessels (flushing, rash, itching) and increased mucus production (runny nose, productive cough), and bronchoconstriction (wheezing, cough). Because histamine is contained in almost all body tissues, [...] it is able to cause a wide variety of symptoms.
So, allergies release histamines, and histamines causes the actual symptoms.
Well, I knew that it’s possible to be allergic to food. I even knew that if you’re allergic to sulfites you should avoid wine. But somehow I’d missed that some foods naturally contain … histamine.
There are many foods that contain histamine or cause the body to release histamine when ingested. These types of reactions are food intolerances, and are different from food allergy in that the immune system is not involved in the reaction. The symptoms, however, can be the same as a food allergy.
This also includes beer, wine and liquor.
The basic takeaway seems to be: IF you have allergies, and your allergies are getting on your case? You might want to avoid food and drink with natural histamines. There’s a long list here. A couple studies linking wine (in particular) with more symptoms in allergy sufferers were discussed here.
(Those who do not have allergies are welcome to pour a glass of wine and rejoice in the comments. Those with allergies, feel free to share other coping methods.)
