Food allergy develops when the body‘s immune system wrongly reacts to a specific food as if it was a harmful substance in the body. The severity of a food allergic reaction differs in different people and can as well be different in the same person during different times. Food allergies are prevalent in young children.

Previous studies of twins suggest that about 80 percent of the risk of food allergies is heritable. However, little is known about these genetic risk factors. Environmental factors are known to play a major role in food allergies. The established environmental factors include dietary exposures, the influence of the microbiota and aerosol allergen exposures. Studies have shown that the more food a child is exposed to in early life, may lead to sensitization. However, there have been few studies to look into the genetic causes of food
