What is cabbage allergy?

Fact Checked

It is important to note that cabbage allergy is considered rare, yet serious reactions can occur. In just a span of a few minutes up to an hour after the ingestion of cabbage or foods that contain cabbage, the immune system will start to produce IgE antibodies that target the proteins present in cabbage. The common symptoms are usually mild but there are cases in which anaphylaxis might occur. This is a life-threatening reaction that involves the entire body. Once the individual experiences breathing difficulty after consumption of cabbage, it is important to seek emergency care.

The protein enzyme extracted from the roots and stems of cabbage is chitinase. This protein has been proven to trigger an allergic reaction in some individuals.

These antibodies will activate the release of histamine that will trigger the manifestation of the signs and symptoms of an allergic response.
