Abstract: University students have low levels of fruit and vegetable consumption (FVC). There is a paucity of research about changing FVC in this population, including the specific use of environmental cues to influence behaviour change. The purpose of this research was to investigate the effect of a cue (a modified plate design and/or plate size) on FVC while exploring explicit cognitions and attitudes in first year undergraduates. Methods: This study utilized an experimental pre-post randomized control group design across six weeks, with two recruitment waves. First year full-time University students living off campus and consuming less than six servings of fruits and vegetables were eligible. Participants (n=39) were randomly assigned to intervention with an 8-inch dinner plate displaying recommended portion sizes, with an 8-inch dinner plate with no design, or a control group. All participants completed a food frequency questionnaire (FFQ), 24-hour food recall (24Hr), demographics, anthropometry and intentions toward FVC, with intervention groups receiving a lesson on Canada's Food Guide in addition to their plate.
