5 Fast Facts About Food Allergies

  • A food allergy is an immune system response in which the body identifies a harmless food protein as dangerous and battles it by creating antibodies, setting off an allergic reaction. Nearly 15 million people in the United States have food allergies, though children are affected the most. Food allergy incidents seem to be on the rise, along with the costs associated. Children’s food allergies cost nearly $25 billion a year, which has prompted many health agencies to increase research about this life-threatening condition in hopes of saving money and lives.

    Because food allergies can be life threatening and are triggered by ingredients found in many of our favorite foods, the FDA created the Food Allergen Labeling and Consumer Protection Act of 2004. This legislation helps protect Americans from the health risk of food allergies by requiring the FDA to label foods with the food source names of any ingredients on the list of top 8 food allergens. If the ingredient includes the allergen in the name, like buttermilk, then it meets the requirement. Otherwise the key allergen is listed in parentheses next to the ingredient or in a list of allergens the product contains.
