Allergy is reaction of human body to certain substances that are normally not harmful. When there is a failure in immune system, it can’t differentiate between dangerous and non-dangerous things and it reacts causing the allergic reaction.
About 3% of the adult population experienced food allergy, but this number is almost twice higher in children. Something these people eat triggers their immune system and it reacts abnormally, starting the reaction against this substance. This defense mechanism can’t tell if this is the bacteria or the virus or something else, so it starts the attack and provoke allergic reaction in the body.
Some of the foods known to provoke allergic reactions are: peanuts, various tree nuts, milk, eggs, soy, wheat, fish, shrimps, shellfishes and lobster.
