[How much nutrition matters for children].

Overweight/obesity is a growing epidemic in the Western world and a leading cause of morbidity and mortality, mainly from cardiovascular disease. Doctors are going to play a major role as they are being called on to adapt their practices to confront it. In particular, nutrition seems to be at the core of obesity in children. The ascending trend of this phenomenon in pediatric age, with inherent healthcare implications, was already reported in epidemiological studies of the mid '90s. Public health programs of primary prevention should be stimulated and recommended, with the aim of promoting diet and lifestyle changes in the general population. In addition, accurate anthropometric measurements should be performed for use by pediatricians, who should focus efforts on preventing obesity during infancy and childhood. Nutrition plays such a pivotal role that it may be considered a valuable treatment strategy for multiple pediatric conditions, including celiac disease, Crohn's disease, short bowel syndrome, galactosemia, congenital deficiency of urea cycle enzymes. In view of all this, it would be advisable that food science be given higher relevance in medical education.
