The immune system is responsible for causing the reaction to a food allergen.

The body system that causes the reaction to a food allergen is the immune system. When a person with a food allergy consumes an allergenic food, their immune system mistakenly identifies the proteins in that food as a threat and triggers an immune response. This response involves the production of antibodies, specifically immunoglobulin E (IgE), which leads to the release of chemicals such as histamine. These chemicals cause the symptoms of an allergic reaction, which can affect different systems in the body, including the circulatory system (causing hives or low blood pressure), the respiratory system (causing wheezing or difficulty breathing), and the digestive system (causing nausea, vomiting, or diarrhea). Therefore, while these other systems may be involved in the allergic reaction, it is ultimately the immune system that is responsible for initiating and coordinating the response.
