Atopic dermatitis is the most common type of eczema. Characterized by itchy, inflamed skin, this chronic skin disorder usually occurs in infants and children, but it may persist into adulthood. About 10 percent of infants and young children are affected by this disorder.

Scientists have speculated that the cause of atopic dermatitis involves a complex interaction between environmental and genetic factors. Research suggests that more than one-third of children with moderate to severe atopic dermatitis may have an unidentified food allergy that is precipitating or worsening this condition. Food allergies affect about three percent of children. The most common culprits are eggs, peanuts, milk, fish, soy products, and wheat. Doctors have long believed that certain foods act as allergens, triggering atopic dermatitis or aggravating its symptoms. This research confirms that there is indeed a link, but whether the dermatitis is caused or worsened by a food allergy remains a mystery.

Experts recommend that children with chronic, difficult to treat atopic dermatitis be screened for potential food allergies. Eliminating offending items has been shown to significantly improve skin symptoms. It is important to remember that identifying food allergens is often difficult and requires medical supervision. Restricted diets may be emotionally or financially difficult to follow. And unless properly monitored, diets with many restrictions could also lead to nutritional deficiencies. With that in mind, consult with your child’s doctor, allergist, or registered dietician to find if your child’s atopic dermatitis could be helped by changes in diet.
