In a "true" food allergy what reacts with an allergen?

Question

Quizplus · Accepted Answer

In a true food allergy, the immune system reacts with an allergen, causing symptoms such as hives, swelling, and difficulty breathing. Digestive enzymes are involved in the breakdown and absorption of food, not the immune response to food. The endocrine system is responsible for hormone production and regulation, not the immune response to food. The respiratory system is involved in breathing and gas exchange, not the immune response to food.
