If a customer comes into a restaurant and has a food allergy there is a 90% chance in the United States that the allergy would be to one of eight different foods including
Tree nuts (almonds, walnuts, etc), milk, eggs, peanuts, fish (bass, cod, etc), shellfish (lobster, crab, shrimp, etc), soy, and wheat are the eight most popular allergies! Hope this is what you need :)
