This talk will start by exploring the different influences on children’s eating behaviour, from birth to adolescence. Then the talk will go on to discuss different interventions which we have developed to improve healthy eating amongst children and adolescents. These will start with interventions we have developed to increase consumption of fruit and vegetables based on planning and increasing motivation, through to an intervention we co-developed with a student advisory group to reduce snacking in adolescents using the Social Norms approach.
