According to a study published in the American Academy of Allergy, Asthma and Immunology scientific meeting in 2012, egg allergies are among the eight most common food allergens that children are most likely to overcome.
Dr. Gupta reported that in their study, a quarter of children were observed to have food tolerance; 55% of them could overcome egg allergies at the age of seven.
Dr. Gupta and the research team conducted an electronic survey with 40104 children from June 2009 to February 2010, in the age group of above 10 years old, 2104 of them is confirmed to suffer from food allergies. On the whole, 28% of those children has developed tolerance to food that they were sensitive to.
By age 10, children who were allergic to milk (45%) or eggs (55%) were more tolerant than those with other food allergies, while children allergic to tree nuts (16%) or shellfish (14%) developed less tolerability.
The average age of becoming tolerant to egg was 7.2 years, and that of milk was 6.0 years. However, the average age of becoming tolerant to tree nuts was 9.6 years, and that of shellfish was 11.6 years. In addition, the age of becoming tolerant to soy, fish and peanuts are 7, 9.3 and 8.4 years old respectively.
Dr. Gupta reported that if allergies only show up as eczema, it is more possible to overcome them. If the symptoms appear as angioneurotic edema, dyspnea or anaphylactic shock, they are less likely to be overcome.
Boys are more likely to overcome allergies; children with severe food allergies are less likely to overcome than those with mild or moderate disease.
