What Are the 12 Food Allergens?

Generally, food allergens cause mild reactions; however, in some cases, they can be life-threatening.

Food allergies are common in adults and children. These allergies occur when the immune system treats food as an invader and launches a fight against it, resulting in allergies.

Studies have identified over 160 foods as allergenic.

The FDA Congress passed the Food Allergen Labeling and Consumer Protection Act of 2004, which identified eight major food allergens:

  1. Milk
  2. Eggs
  3. Fish
  4. Crustacean shellfish
  5. Tree nuts
  6. Peanuts
  7. Wheat
  8. Soybeans

Common symptoms of food allergies

These allergies can be mild or life-threatening. If someone has food allergies, they may carry emergency injectables like epinephrine.

Common symptoms include:

  • Skin rashes
  • Swelling of the tongue
  • Sneezing
  • Difficulty breathing
  • Stomach upset
  • Hives
  • Diarrhea

These allergens cause the immune system to fight against them. They can develop at any stage but are often seen in kids or young adults.
