Digital Halalan-Toyyiban Intervention to Enhance Dietary Knowledge, Attitudes and Practices among University Students: An Exploratory Assessment

This pilot study assessed the effectiveness of a Religious-Based Digital Intervention Tool (RB-DIT), grounded in the Halalan-Toyyiban dietary concept, to improve knowledge, attitudes, and dietary practices (KAP) among university students. 14 medical students participated in a 10-day intervention using a web-based educational platform. Paired sample t-tests revealed significant post-intervention improvements in knowledge (e.g., K7: M = 1.429, p < 0.001), attitudes (A1: M = 1.000, p < 0.001), and practices (P11: M = 0.929, p < 0.001). The RB-DIT demonstrated strong internal consistency (Cronbach’s α = 0.823) and received high user satisfaction (M = 3.93 out of 4.00). These findings underscore the potential of digitally delivered religiously grounded content to foster informed and ethical dietary choices among young adults. The RB-DIT offers a culturally congruent and scalable approach to nutrition education, as it merges Islamic principles with interactive, learner-centred design. This combination facilitates meaningful engagement and supports sustainable behavioural improvements in line with religious-based values.
