Authors' conclusions: aluminum content of some infant formulas is high, particularly in preterm infant formulas and soy milk designed for children with cow's milk allergy or intolerance. Children can be very vulnerable to early exposure to aluminum. Therefore it has to be highlighted the urgent need to reduce to the minimum possible the content of this product in the formulas.
Reviewers' commentary: presence of aluminum in infant formulas is shown in several studies. The formulas with the highest concentrations were the preparations in powder, the soy-based ones and the designed for preterm infants. The toxic effects of aluminum on the metabolism of both bone and neurodevelopment are shown in infants undergoing parenteral nutrition. Pediatricians and health professionals in charge of child health must ensure, whenever possible, that infants receive breast feeding, especially if they are premature.
