What are the most common food allergies?

Allergic reactions are abnormal immune responses that develop after exposure to a given food allergen.[15] Food allergens account for about 90% of all allergic reactions.[16] The most common food allergens include milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat,[17] which are referred to as "the big eight".[18] In April of 2021, President Joe Biden signed the FASTER Act into law. This landmark food allergy law recognizes sesame as the ninth mandatory food label allergen. It also encourages research that will improve the quality of life for food allergy families, and that could potentially lower the rates of future food allergies.[19][20]
