Although a spinach allergy is rare, some individuals may be sensitive to specific proteins found in spinach. In addition, due to cross-reactivity, individuals may experience an adverse reaction to spinach if they have an allergy to other plants in the amaranth family. An individual's immune system triggers an allergic reaction to spinach. The body views certain substances (proteins) as toxic and produces IgE antibodies to combat these contaminants. These antibodies cause histamine to be released, which triggers allergic reaction symptoms.
