Food allergy refers to a specific allergic reaction,it happens due to the bad food that we have and by our food eating items.Most food allergies in children are triggered by cows milk, egg, nut, sesame seed, soy, wheat and seafood proteins. Food allergies can have effects at several different sites in the body, including the mouth, throat, lungs, skin and gastrointestinal tract. Often more than one site in the body is affected at the same time due to this food allergy.Reasons for this food allergy are not identified so easily
* Foods are rarely eaten on their own. For example, a cake may contain milk, eggs and peanuts, and investigations are required to determine which ingredient caused the reaction.
* Cooking food can change the protein structure of the food and make it more or less likely to cause a reaction (for example, pasteurized milk is less likely to cause a reaction than unheated milk, and roasted peanuts are more likely to cause a reaction than peanuts that are not roasted).
The best treatment of food allergies is avoidance,and consulting the doctor immediately.
