Integration of behavioural feedback in web‐based systems nutrition learning among university students

This study evaluated whether nutrition knowledge and healthy eating patterns can be achieved through web‐based systems, a secondary analysis of learning activities and assessment records. Students used online dietary recording systems to capture food intake data for 2 weeks. The first cohort used a food photo‐upload method and the second cohort used a food text‐searching (TS) method. We compared nutrient intake profiles, nutrition knowledge, and reflective journals of the 2 groups. Interaction effects were tested by 1‐way multivariate ANOVA on outcomes between groups (p < .05). More reflective and action statements in reflective journals were observed in the TS group. The photo‐upload group exhibited significant improvement in saturated fat, sodium, cholesterol, and fat consumption (p < .001), as compared with TS group. Web‐based dietary systems can be adopted in nutrition education to effectively enhance students' nutrition knowledge and help them to reflect on their dietary patterns.
