Question: What are the major food allergens and what are common symptoms of an allergic reaction to food?
Answer: The typical foods in the United States that children and adults have reactions to are eight foods or food groups that are milk, egg, peanut, wheat, soy, fish as a group, shellfish as a group and then tree nuts -- and the tree nuts might be walnuts or pecans. The typical symptoms that you have are related to three organ systems: the skin, the GI system and the respiratory system.
Skin symptoms are hives or a red, itchy rash. The GI symptoms are vomiting or diarrhea or severe abdominal pain. And then the respiratory symptoms can be both upper, in the nose and eyes, as well as lower. And the lower respiratory symptoms are coughing or swelling of the throat or wheezing that are probably the most concerning.
