Food Dudes is an award-winning healthy eating programme for children (age 2-11) that combines leading behavioural science techniques with fun activities. It is based upon 3 key psychological principles, Role-Modelling, Repeated Tasting and Rewards. The programme is very effective in bringing about large and long-lasting increases in children’s consumption of fruit and vegetables and in reducing consumption of sweet and fatty foods. This makes a major contribution to the prevention of childhood obesity. It is the only Programme in the UK that has been shown to do this. Food Dudes is a whole-school approach and has been specially designed for delivery by teachers in schools.
