Objectives To apply a healthy dietary program with reduced sodium intake, developed using data from the Korea National Health and Nutrition Examination Survey (KNHANES), focusing on the sodium intake level and eating patterns.
Methods The program was implemented using a living lab model, an open innovation ecosystem for user-centered problem-solving. Analysis of the KNHANES data revealed that older age groups had a low energy intake but a high sodium intake, particularly among those who frequently dined out. The program was designed to improve sodium-reduction literacy and enhance practical competency. Over four weeks, 40 participants tracked their dietary intake and worked with a clinical nutritionist through a process of diagnosis, experience, improvement, and expansion. A self-administered survey was conducted before and after the program to assess effectiveness.
Results Participants were four teenagers (10%), 26 in their twenties (65%), and 10 aged ≥ 30 years (25%), with eight males (20%) and 32 females (80%). Post-program analysis showed significant improvements in sodium-related nutrition knowledge (P < 0.01), with increased agreement on adopting low-sodium intake practices (e.g., interest in sodium content, choosing lower-sodium foods). Nutrient intake analysis showed a decrease in energy, carbohydrates, lipids, and proteins (P < 0.001), with sodium intake decreasing from 3,382.37 mg/d to 2,119.05 mg/d (P < 0.001).
Conclusion The community-based, living lab model for the sodium-reduction program effectively improved participant sodium-reduction literacy and practical competency, suggesting that step-by-step, autonomous learning, can reduce sodium intake and promote healthier eating habits.
