In the United States, the Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA) holds that approximately two percent of adults and five percent of young children in the United States have food allergies and that eight foods account for approximately 90 percent of these allergies:
- Fish (e.g., bass, flounder, cod)
- Crustacean shellfish (e.g., crab, lobster, shrimp)
- Tree nuts (e.g., almonds, walnuts, pecans)
Pursuant to this Act, the U.S. Food and Drug Administration requires that these potential allergens be listed on product labels.1
Canada and the United Kingdom have similar lists, but add mustard, sesame, sulphites, triticale (a wheat-rye hybrid), and lupin (a bean sometimes added to flour products or eaten pickled).2, 3
The following figures provide estimates of affected groups in the United States:
|Vegetarian or vegan||5 - 10%, depending on age|
|Gluten intolerant or sensitive, or celiac||10%|
|Jewish, Muslim, or Hindu||4%|
|Lactose intolerant||10 - 90%, depending on race and age|
|Severe food allergies||5% of U.S. children|
