The objective as formulated in the JPI (Joint Programming Initiative - A healthy diet for an healthy life) is “to understand the determinants, at both the individual and group levels, regarding dietary, physical activity and sedentary behaviours using a broad multidisciplinary approach, including biological, ecological, psychological, sociological, economic and other socio-economic perspectives, and their interrelationships and to translate this knowledge into a more effective promotion of a healthy diet and physical activity.”
