Both immunologic and non-immunologic mechanisms can provoke systemic reactions following food ingestion. Histamine is the only mast cell mediator which has been demonstrated to be elevated in the serum as a result of systemic allergic reactions to food. In individuals highly sensitive to foods, airborne exposure to food allergens can produce anaphylactic reactions. Crossreacting allergens present in some foods and in natural rubber latex can lead to systemic reactions following either latex exposure or food ingestion.
免疫和非免疫机制都可能在摄入食物后引发全身反应。组胺是唯一一种已被证明在对食物的全身过敏反应中血清水平会升高的肥大细胞介质。在对食物高度敏感的个体中，通过空气接触食物过敏原可产生过敏反应。某些食物和天然橡胶乳胶中存在的交叉反应性过敏原，在接触乳胶或摄入食物后都可能导致全身反应。
