What is the most common type of food allergy?

The most common type of food allergy is to peanuts. It is estimated that up to 1% of the general population is allergic to peanuts, making it one of the most common food allergies. Other common food allergies include:

• Tree nuts (such as walnuts, almonds, and cashews)
• Milk
• Eggs
• Soy
• Wheat
• Shellfish (such as shrimp, lobster, and crab)
• Fish

Food allergies occur when the immune system reacts to a certain protein found in food as if it were harmful. Symptoms can range from mild to severe and can include hives, itching, swelling, difficulty breathing, and anaphylaxis (a severe allergic reaction that can be life-threatening).

If you suspect that you have a food allergy, it is important to see a doctor for a proper diagnosis. Treatment may include avoiding the allergen and carrying an epinephrine auto-injector in case of a severe allergic reaction.
