What percentage of food allergic reactions are caused by the major eight food allergens (Milk, Eggs, Peanuts, Tree Nuts, Fish, Crustaceans, Wheat, and Soy)?

• A. 70%
• B. 90%
• C. 50%
• D. 100%

Answer: (B)

The main idea is that a small group of foods accounts for the vast majority of allergic reactions. The major eight allergens—milk, eggs, peanuts, tree nuts, fish, crustaceans, wheat, and soy—are responsible for about 90% of reported food allergy reactions. This is the standard figure used in practice and labeling requirements, reflecting epidemiological data that these eight foods trigger roughly nine out of ten reactions. The remaining roughly 10% come from other, less common foods, so 100% would be inaccurate. Choices like 70% or 50% underestimate the impact of these eight foods, and 90% best matches the observed distribution.
