Certain foods and things contain substances that causes allergic reaction- you beckon it allergens.

The subsequent time such substance get into the body even surrounded by the smallest amount, the IgE antibodies sense it and signal your immune system to release histamine and other chemicals into your bloodstream.

There is a protein in these substances to which the individual is hypersensitive to, so when ingested, the immune system detects this protein and starts stale an immune response. The most important aspect of this response (in allergic people) is the activation of flagstaff cells. These cell contain granules, when activate, the cells degranulate, thus releasing substances such as histamine and leukotrienes and indisputable cytokines. Histamine is a potent vasodilator and bronchoconstrictor, thus their skin becomes red an itchy (in skin allergies) and they find it difficult to breath (ingestion of insanitary protein).
