Food allergies are the body’s response to proteins found in food. For more than 12 million Americans alone, food allergy is a significant medical condition. All food contains proteins that enter the body when the food is eaten, or in some cases if it is touched. Allergic reaction occurs when the body reacts to these proteins as if they were harmful, and for individuals with food allergy, the offending food is harmful.
