Food allergies are a growing concern for many people around the world. An allergy occurs when the body’s immune system reacts abnormally to a particular food item, causing symptoms that range from mild to severe. In this article, we will explore some common food allergens, their triggers, and how to effectively manage food allergies.

Common Food Allergens

There are eight main food allergens that account for the majority of food allergies in both children and adults. These include:

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

It is important to note that these are not the only food allergens, and individuals can be allergic to other foods as well.

It is essential for individuals with food allergies to be aware of these triggers and take necessary precautions to prevent allergic reactions.
