[Cow milk protein allergies: primary prevention. Nutritional aspects].

In 2001 the Nutrition Committee of the Spanish Association of Pediatrics, published a position paper on "Recommendations on the use of formulae for the treatment and prevention of adverse reactions to cow milk proteins" (An Esp Pediatr. 2001;54:372-9). Since most of the recommendations given in this report still remain effective, the Nutrition Committee of the Spanish Association of Pediatrics reaffirms its support of the data expressed in it. In the present publication we only approach the aspects that have changed due to new knowledge and the accumulated clinical experience, especially on the primary prevention of allergy to cow milk proteins, and on the basis of it, the present recommendations for this prevention are set out. In addition, the importance of the nutritional aspects in all infants and small children receiving special nutritional formulae and exclusion diets are reviewed.
