Childhood obesity is a worsening social emergency. It affects even the youngest children and has become a major issue in schools throughout the developed world and beyond. In Italy, recent data from the Ministry of Health show that more than 1 million children, a quarter of all young people between 6 and 11 years old, are overweight; 12% of the child population is obese. In southern regions, the situation has reached staggering proportions: half of all children are overweight or obese. In fact, Italy is now third in the world for childhood obesity – behind the USA and Portugal.
