What type of food is most likely to cause a serious allergic reaction?

Foods containing common allergens such as peanuts, tree nuts, dairy, eggs, fish, shellfish, soy, and wheat are recognized as the most likely to cause serious allergic reactions. This is because these foods are classified as the most prevalent allergens that can trigger anaphylaxis and other severe allergic responses in susceptible individuals.

Peanuts and tree nuts, for instance, can provoke immediate and life-threatening reactions. Dairy and eggs can also lead to significant reactions in those with specific allergies. Fish and shellfish are notorious for being triggers as well, with shellfish allergies often being lifelong. Soy and wheat might be less common but can still lead to serious health issues for individuals with allergies.

Fruits and vegetables, while they can cause allergic reactions in some individuals, generally do not lead to the same level of severe reactions seen with the common allergens mentioned. Similarly, unseasoned rice and bread, which are typically safer staples, and cooked meats, which do not contain common allergens, pose a much lower risk of triggering serious allergic reactions. Thus, option A accurately reflects the foods associated with high allergy risks.
