Food allergies affect millions of people worldwide, with reactions ranging from mild discomfort to severe, life-threatening situations.
Among the plethora of food allergens, some stand out as the most common triggers for allergic reactions. Understanding these common food allergies is crucial for both individuals with allergies and those around them.
What is a food allergy?
A food allergy is an abnormal immune response triggered by consuming certain foods. When a person with a food allergy ingests the allergenic food, their immune system mistakenly identifies it as harmful and releases chemicals, such as histamine, to protect the body. This immune response leads to various symptoms, ranging from mild itching or hives to severe anaphylaxis.
Identifying common food allergens
While virtually any food can cause an allergic reaction, some are more commonly implicated than others. The most prevalent food allergens, often referred to as the “Big Eight,” include:
Milk
Milk allergy is particularly common in infants and young children, affecting approximately 2-3% of infants globally. Symptoms may include hives, digestive issues, and even respiratory problems upon consuming milk or milk products.
Eggs
Egg allergy is prevalent in children but may be outgrown over time. Symptoms range from mild skin reactions to severe respiratory distress. Individuals with an egg allergy must be cautious when consuming baked goods, processed foods, and certain vaccines.
Wheat
Wheat allergy is more common in children and often manifests as skin reactions or digestive issues. It is distinct from celiac disease, which is an autoimmune disorder triggered by gluten, a protein found in wheat and other grains.
Soy
Soy allergy can cause a range of symptoms, including skin reactions, digestive problems, and respiratory issues. Soy is a prevalent ingredient in processed foods, making it challenging for individuals with soy allergies to avoid.
Shellfish
Shellfish allergy is one of the most common adult-onset food allergies. It includes reactions to crustaceans like shrimp, crab, and lobster, as well as mollusks like clams, mussels, and oysters. Symptoms can range from mild itching to severe anaphylaxis.
Fish
Fish allergy often persists into adulthood and can cause severe reactions upon ingestion. Avoidance of fish and fish products is crucial for individuals with this allergy to prevent allergic episodes.
Tree nuts
Tree nut allergy encompasses reactions to a variety of nuts, including almonds, walnuts, cashews, and pistachios. Even trace amounts of nuts can trigger severe allergic reactions in susceptible individuals.
