Background : The Food Balance Wheel, the current Korean food-based dietary guideline, fails to convey personalized recommendations on serving size, proportionality between five food groups, and fluid intake. An alternative design, the Food Balance Lunchbox, was designed in the CCW Treemap format for more effective visualization of personalized calorie intake and proportionality. Labelled photo icons exemplify serving sizes in weight and volume. Text information further clarifies the proportionality in percentages and recommended fluid intake in cups. Methods : In a randomized trial with 200 participants, the two designs were tested. Part I compared communication performance in terms of Moderation, Diversity, Proportionality, and Hydration tasks. Part II collected ratings on Interestingness, Aesthetics, and Proportionality Visualization for each design. Results : Part I scores were higher for Lunchbox (Mdn = 19) than Wheel (Mdn = 5) at p < 0.001 in total, and for each of the four tasks. Qualitative data confirmed the participants’ appreciation of labelled photo icons that enhanced information granularity on serving size. Part II scores, however, were higher for the Wheel design in terms of Interestingness and Aesthetics, while Proportionality Visualization scores were similar between the designs. The Lunchbox design was perceived as dull and too crowded with information. Conclusions : The Food Balance Lunchbox, while more informative than the Food Balance Wheel, needs improvements. In future studies, an interactive version will be developed with contextual presentation of information, as well as a customizable food list and enhanced proportionality visualization.
