Few studies have examined the antecedents of nutritioninvolvement. Similarly, conflicting results have been recorded on the relationship between nutritioninvolvement and knowledge, knowledge and dietary behaviors, and nutritioninvolvement and dietary behaviors.
This paper addresses these research gaps by exploring the role of regulatoryfocus as an antecedent of nutritioninvolvement. It also examines the effect of nutritioninvolvement on nutritionknowledge and the effects of both involvement and knowledge on diet adjustment. A large-scale study with 1125 Taiwanese consumers demonstrates a positive effect of promotion focus and no significant effect of prevention focus, on nutrition involvement. Income moderates the effect of promotion focus on nutritioninvolvement, which in turn has positive effects on nutrition knowledge and diet adjustment. Nutritionknowledge also has a positive effect on diet adjustment.
The study clarifies these relationships and provides suggestions to policy making.
