Severe nutrition problems afflict more than half the world's population and food systems will need to undergo significant changes to improve people's diets and lives, speakers told country representatives and experts as they opened a meeting organized by FAO and the World Health Organization (WHO) yesterday. The 13-15 November event is a preparatory technical meeting designed to lay the groundwork for the Second International Conference on Nutrition (ICN2), scheduled to take place in 2014, from 19 to 21 November. The aim is to boost coordination of international efforts to tackle the agricultural, economic, health, food system and other factors that negatively influence what and how people eat, especially in developing countries. "It is clear that the ways in which food is managed today are failing to result in sufficient improvements in nutrition. The most shocking fact is that over 840 million people still suffer from hunger today, despite the fact that the world already produces enough food for all, and wastes one-third of it" said Jose Graziano da Silva, Director-General of FAO. "The total amount of food produced but not consumed would be enough to feed an additional two billion. The truth of the matter is that, today, consumers are not receiving the right signals from current policies about how to eat healthily. That is what we need to address," Graziano da Silva added.
