Everything About Allergy

Food allergy is different from food poisoning or food intolerance. It is the immune system’s reaction to certain food proteins. These proteins that trigger an allergic reaction is called food allergen. A person allergic to certain foods are advised to avoid eating these foods, and those who are sensitive to the allergens should also avoid touching the food or anything it has come into contact with, or inhaling the aroma of the food.

Symptoms of food allergy include swelling of the eyelids, face lips and tongue, also called angioedema. This may result to difficulty in breathing if the tongue, larynx and trachea are swollen.
