Peanuts: One of the most common food allergens, peanut allergies can be severe and life-threatening. Reactions can occur from direct consumption or cross-contamination.
Tree Nuts: This category includes nuts such as almonds, walnuts, hazelnuts, cashews, pistachios, and Brazil nuts. Like peanut allergies, tree nut allergies can also be very severe.
Milk: Cow’s milk is a common allergen, especially among infants and young children, although many outgrow it. Milk allergy differs from lactose intolerance, which is a digestive issue.
Eggs: Another allergen frequently seen in children, though many children outgrow this allergy by the time they reach school age.
Fish: Allergies to fish can be serious and lifelong. People allergic to one type of fish are often advised to avoid all types due to potential cross-reactivity.
Wheat: This is often confused with celiac disease, which is an autoimmune disorder triggered by gluten. Wheat allergy involves an immune response to one of the proteins found in wheat.
Sesame: Although less common, sesame allergies are growing in prevalence and can cause severe reactions. Sesame seeds can be found in a variety of foods, including bread, hamburger buns, and Middle Eastern dishes like hummus.
Mustard: Less common but recognized in some regions, especially in Europe, as a significant allergen. It can be found in a variety of condiments, marinades, and salad dressings.
