Food and human behaviour: consumption, waste and sustainability

The current global economic crisis implies new problems of knowledge and management of food and nutrition safety and security with respect to all their components.It is not by chance that the 2013 World Food Day theme, Sustainable Food Systems for Food Security and Nutrition, insisted that this fundamental aspect of daily life profoundly influences − as a risk or a protective factor − not only the health of each subject but the health of the planet as a whole. From this perspective, the dynamics of consumption and waste assume a new meaning, especially in relation to the emerging idea of sustainability in food and nutrition.
