Common Food Triggers For Allergies

Food allergies, like many other allergies, are an immune system reaction to a substance referred to as an allergen. A common seasonal allergy, for instance, is to pollen. Food allergies occur when someone eats a particular food. The most common signs of a food allergy include itching in the mouth, hives, eczema, itchy skin, swelling in the lips and face, trouble breathing, and wheezing. Many also deal with gastrointestinal symptoms like diarrhea, nausea, vomiting, and abdominal pain.
