Food Allergy Basics

What Is a Food Allergy?

A food allergy occurs when the immune system reacts to a specific food as if it were harmful. Even small amounts of the food can trigger a reaction.

Common Symptoms

Food allergy symptoms can affect multiple systems in the body and may include:

  • Hives or skin rash
  • Swelling of the lips, face, or throat
  • Nausea or vomiting
  • Abdominal pain
  • Difficulty breathing
  • Severe reactions (anaphylaxis)

Common Food Allergens

The most common food allergens include:

  • Peanuts
  • Tree nuts
  • Milk
  • Eggs
  • Wheat
  • Soy
  • Fish
  • Shellfish

However, any food can potentially cause an allergic reaction.

Why Accurate Diagnosis Matters

Not all food reactions are allergies. Some may be intolerances or sensitivities. Accurate diagnosis helps:

  • Avoid unnecessary food restrictions
  • Identify real risks
  • Create an effective management plan

Managing Food Allergies

Management typically includes:

  • Avoiding trigger foods
  • Reading food labels carefully
  • Carrying emergency medication (such as epinephrine)
  • Having an action plan in place

Education is essential for both patients and caregivers.
