RESUMO
BACKGROUND/OBJECTIVES: The basic treatment for cow's milk allergy (CMA) is the elimination of all cow's milk proteins (CMP) from the diet. This study aimed at characterizing the diet of children with a diagnosis of CMA, to assess the degree of adherence to the elimination diet and to evaluate the factors associated with the adherence and age of recovery. SUBJECTS/METHODS: From a birth cohort study, food records of 267 children diagnosed with CMA were studied to define how strictly the elimination diet was adhered to. Subsequent food records were studied to assess the age at reintroduction of milk products in the child's diet. RESULTS: The families adhered to the elimination diet of the child with extreme accuracy in 85% of the cases. Older and monosensitized children had more often small amounts of CMP in their diet, possibly because of the absence of nutritional information by a dietitian/nutritionist. Adherence to the diet was neither related to any other sociodemographic factor studied nor to the age at reintroduction of milk products into the diet. CONCLUSIONS: The therapeutic elimination diet of children diagnosed with CMA was well adhered to. Low intakes of vitamin D, calcium, and riboflavin are of concern in children who follow or have followed a cow's milk-free diet.
