Summary
Brief summary
Australians are not eating enough vegetables. The CSIRO Healthy Diet Score survey has found that reported to ‘always’ consume 3 different types of vegetables at their evening meal were twice as likely to meet their daily requirements.
An explosion of health promoting mobile apps has occurred in recent years including healthy eating ones. However, most mobile apps are not scientifically developed and have yet to undergo rigorous evaluation. Therefore, this research aims to develop and test the useability and effectiveness of a mobile App to increase the variety and amount of vegetables participants consume.

Aims / Objectives:
The overarching aim is to develop a highly engaging mobile App which motivates adults to increase the variety of vegetables they consume at their main/evening meal to at least 3 different types, as impetus to increase their total variety and the total amount of vegetables they usually consume.
