Most symptoms of<unk>  are related to the action of immunoglobulin E (IgE) and other anaphylatoxins which act to release histamine and other mediator substances from mast cells (degranulation). In addition to other effects, histamine induces vasodilation of arterioles and constriction of bronchioles in the lungs, also known as bronchospasm. Symptoms can also include mild itchiness, hives, angioedema, facial swelling, rhinitis, vomiting, diarrhea, acute abdominal pain, exacerbation of atopic eczema, asthma, and cardiac arrest. Anaphylaxis may occur. Tree nuts and soy People with confirmed<unk>  may have cross-reactivity to tree nut, soy, and other legumes, such as peas and lentils and lupinus. The cause of cross-reactivity results from similarity in the structures of storage proteins between the food sources. Allergenic proteins are grouped by protein families: cupins, prolamins, profilin and others.<unk> s and soybeans have proteins in the cupin, prolamin, and profilin families, while lentils contain cupin proteins. Reviews of human clinical trials report that 6–40% of people with a confirmed<unk>  will have allergic symptoms when challenged with tree nuts or legumes.
