[Role of food allergy in atopic dermatitis]

Food allergy is one of the main causes of atopic dermatitis. Its frequency was established at 41.3% in our study. Eggs, cows milk and wheat were the foods most often responsible for DA. Proof by elimination-reintroduction is the best diagnostic criterion in food allergy, leading to suppression of the food if its nutritional importance permits this. This food suppression leads to 84% clinical improvement of DA.
