Metabolomics is of particular interest in the field of nutrition, since nutrients interact with a number of targets, metabolic pathways and functions.~A suitable biofluid to study nutrient intake is urine, which is the most commonly used biological sample for metabolomic analysis and can be collected with simple and non-invasive methods.~Up to now, no studies have investigated healthy term infants metabolome and its modulation according to different dietary regimens such as formula-feeding or breastfeeding.~The aim of this study is to evaluate, with untargeted modalities, the urine metabolomic profile of a group of infants fed with a standard formula, a group of infants fed with a formula supplemented with functional ingredients and a group of breast-fed infants.~Formula-fed infants participate to PLA-LENI-09 study (NCT01197365). We have included also a control group of breast-fed infants, as, from a scientific point of view, they represent the gold standard and no data are available on their metabolomic profile.
The purpose of this study is the evaluation with untargeted modalities, of the urine metabolomic profile in a group of infants fed with a standard formula, a group of infants fed with a formula supplemented with functional ingredients and a group of breast-fed infants.
