What causes an allergy to grapefruit?
Allergic reactions to grapefruit are generally associated with oral allergy syndrome (OAS) or pollen-food allergy. OAS is caused by cross-reactivity to allergens in pollen and raw fruits, vegetables, or some tree nuts. The immune system views pollen and specific proteins found in food as harmful and produce IgE antibodies to combat them. Unfortunately, these antibodies cause a chemical called histamine to be released in the blood, which prompts an allergic reaction.
