Tailoring Infographics of the Norwegian National Dietary Guidelines

Abstract

This research explores how infographics can enhance public understanding of nutrition based on the Norwegian Directorate of Health’s dietary guidelines. Although these guidelines are designed for the entire population, the Directorate has indicated to target younger Norwegians in their outreach efforts. To make the guidelines more accessible across age groups, we transformed the Directorate's text-based content into engaging infographics. Three mid-fidelity prototypes were developed: Infographic 1 emphasizes simplicity with basic illustrations and structured text; Infographic 2 uses a colorful segmented wheel; and Infographic 3 combines detailed illustrations with unboxed text. These designs were evaluated by 72 participants in age-stratified focus groups. Results showed a preference for Infographics 1 and 3, valued for heir clarity and visual appeal, with age and gender influencing preferences. Based on participant feedback, revised versions of the infographics were created. The findings confirm that well-designed infographics can significantly boost engagement, interaction, and retention of nutritional information.
