Identity and Self-efficacy Theories were used to examine the relationship between healthy-eater identity, self-efficacy for healthy eating and healthy eating. Measures of healthy-eater identity, perception of healthy eating, nutrition knowledge, self-efficacy for both intake of fruits and vegetables and foods of low nutritional value were completed by 101 university students and staff. Two weeks later, participants recalled recent consumption of (a) fruits and vegetables and (b) foods of low nutritional value. For both eating outcomes, healthy-eater identity was a significant predictor after controlling for nutrition knowledge. The addition of self-efficacy improved prediction in the case of both eating outcomes.

Key Words: healthy-eater identity • healthy eating • identity theory • self-efficacy theory
