ABSTRACT
In the last few years, owing to their potential or proven benefits in infancy, new additions of nonnutritive components and semiessential nutrients to infant formulas have been implemented by a number of milk formula manufacturers. Nucleotides and long-chain polyunsaturated fatty acids are the most relevant recent additions to infant formulas, and these have been approved by a number of international agencies. Other nutrients-namely, amino acids, aminosugars, and glycolipids-a few of them with prebiotic functions, are under consideration to be added in the near future (2). Moreover, selected strains of bacteria with probi-
otic functions have recently been added to follow-on infant formulas in the European Union and other countries.
