Why kid develop food allergies

New York: Many children suffer from food allergies that are significant and their ignorance can cause skin rash to a potentially lethal anaphylactic shock, life threatening allergic reaction. According to a new study, the good news is that many affected children outgrow their allergy, presumably as the immune system learns to tolerate food initially mistaken as "foreign".

According to researchers the children, who have more limited exposure to novel foods than adults, are more susceptible to food allergies. The study is the first to demonstrate that consumption of a normal diet stimulates cells in the gut that suppress rejection of food by the immune system. Like pathogens, food displays macromolecular markers known as antigens that announce to the immune system that food is "foreign".
