The exact way a food ingredient in the diet causes the symptoms of food allergy is unknown. Sensitivity reactions, such as itching of the skin, vomiting, or diarrhea, may occur within minutes to hours, or even several days later. The offending dietary ingredient is not necessarily something new in the diet.
