Food allergies are also known as food allergy, the immune response is due to a certain food or food additives caused by IgE-mediated and non-IgE-mediated, resulting in digestive system or systemic allergy. Most foods can cause immune reactions almost antigenic molecules are proteins, the majority of water soluble glycoprotein. Simply put, when a certain protein in the food into the body, the immune system as caused by the invasion of pathogens the immune system attacks the immune system to release substances in combination with food will generate a lot of chemicals, cause skin irritation, diarrhea , indigestion, headache, sore throat, asthma and other allergic symptoms.
Thousands of types of food, but an allergic reaction caused only by a handful of food, about 90% of allergic reactions is made from milk, eggs, peanuts and wheat caused by food.
