Soy is one of the main staples in the United States food chain. Though we do not eat soy beans the way we eat corn, soy products and extracts are used in a number of our foods and recipes. Since soy is very widespread, it is important to read all food labels and recipes when serving customers with a soy allergy. A single protein is enough to cause an allergic reaction.
When preparing a dish for a guest that has a soy allergy, avoid using the following ingredients as they may contain soy proteins:
Textured vegetable protein
Soy can also be found in a variety of common food products that may be used to prepare certain menu items.
Canned broth and soups
Canned tuna and meat
Low-fat peanut butter
