The development of healthy eating habits in adolescents is challenging. Resultantly, health educators are turning to digital devices to engage young people in nutrition education. This paper focuses on the development and evaluation of a computer game (Test Game B) to support healthier food choices. Test Game B was developed at an Australian university and trialled with 72 tertiary student volunteers along with a control game (Control Game A). Both games provided information related to the progression of food along the digestive tract with knowledge of digestion, nutrition, a healthy diet and attitudes to food choice measured before and after game use. Change in these indicator variables assessed game effectiveness. The study found that the transformational aspects of problem-based learning within a digital context can support healthier food choices in young people, whilst pre-service health education teachers may require learning in food digestion to support nutrition education in schools.
