Abstract
Pediatric obesity represents an important health issue. In recent years applications of metabolomics have led to evaluation of responses to the various nutrients (nutrigenomics), in particular to lipids, in diseases such as obesity and diabetes.
The experimental data and the studies in pediatrics that evaluated the metabolic condition in infant obesity are presented. It is thus to be hoped that future progress in connection with this new technique, together with a metabolomic study of mother's milk and formula milk, will lead to the creation of better personalized nutritional therapies to prevent infantile obesity and the chronic pathologies of adults connected with it.
