An interventional study of Web-Based Sustainable Food Literacy Program and Web-Based General Nutrition Education Program in Food Literacy and Healthy Eating, sponsored by Kaohsiung Medical University Chung-Ho Memorial Hospital. Not yet recruiting at 1 site in Taiwan. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-11-05.

This randomized controlled trial will evaluate the effectiveness of a web-based sustainable food literacy program for university students in Taiwan.
A total of 180 university students will be randomly assigned to one of three groups: a sustainable food literacy intervention group, a general nutrition education comparison group, or a control group. The two educational programs will be delivered online over 6 weeks and will include 11 learning units.
Participants in all three groups will complete assessments before the intervention, immediately after the 6-week intervention period, and 3 months after the intervention. The primary outcome is comprehensive food literacy. Other outcomes include different domains of food literacy, sustainable eating intentions and strategies, and healthy eating behaviors.
The study aims to determine whether the sustainable food literacy program improves food literacy compared with the control condition and whether it provides additional benefits compared with general nutrition education.

Exclusion Criteria:
-None.
Participants will receive an 11-unit web-based sustainable food literacy program delivered over 6 weeks. The program includes scenario-based learning materials, visual educational content, quizzes with corrective feedback, and reflective learning activities related to food literacy, sustainable eating, and food-system concepts.
Behavioral: Web-Based Sustainable Food Literacy Program
Participants will receive an 11-unit web-based general nutrition education program delivered over 6 weeks using the same online platform and a similar educational schedule. The program uses authoritative nutrition education materials and five-item quizzes with corrective feedback but does not include sustainability- or food-system-specific content.
Behavioral: Web-Based General Nutrition Education Program
Participants will not receive either web-based educational program during the 6-week intervention period. They will complete the same outcome assessments as participants in the other study groups.
The intervention is a 6-week web-based educational program consisting of 11 learning units. Units 1-10 are delivered as two units per week during the first 5 weeks, followed by an integrative unit in week 6. The program focuses on comprehensive food literacy and sustainable eating and includes scenario-based stories, visual educational materials, quizzes with corrective feedback, reflective activities, and food-system- and sustainability-related concepts.
The active comparator is a 6-week web-based general nutrition education program consisting of 11 learning units. Units 1-10 are delivered as two units per week during the first 5 weeks, followed by an integrative unit in week 6. Each unit generally includes authoritative nutrition education materials and a five-item quiz with corrective feedback. The program focuses on general healthy eating and does not include sustainability- or food-system-specific concepts.
Comprehensive Food Literacy Total Score
Comprehensive food literacy will be assessed using a culturally adapted 25-item Comprehensive Food Literacy Measurement Tool. Items are rated on a 5-point scale from 1 (strongly disagree) to 5 (strongly agree). A mean total score will be calculated across the 25 items, ranging from 1 to 5, with higher scores indicating greater comprehensive food literacy.
Time frame: Immediately after the 6-week intervention (T1)
Comprehensive Food Literacy Total Score at 3-Month Follow-Up
Comprehensive food literacy will be assessed using the same culturally adapted 25-item Comprehensive Food Literacy Measurement Tool. Items are rated from 1 to 5, and a mean total score ranging from 1 to 5 will be calculated, with higher scores indicating greater comprehensive food literacy.
Time frame: 3 months after completion of the 6-week intervention (T2)
Comprehensive Food Literacy Domain Scores
The 25-item Comprehensive Food Literacy Measurement Tool includes five domains: production (7 items), selection (5 items), preparation and cooking (7 items), intake (3 items), and disposal (3 items). A mean score ranging from 1 to 5 will be calculated for each domain, with higher scores indicating greater food literacy in that domain.
Time frame: Immediately after the 6-week intervention (T1) and 3 months after the intervention (T2)
Sustainable Eating Action Intention
Sustainable eating action intention will be assessed using three items adapted from the Sustainable Food Literacy Scale. Items are rated on a 7-point scale from 1 (strongly disagree) to 7 (strongly agree). A mean score ranging from 1 to 7 will be calculated, with higher scores indicating stronger intentions to adopt sustainable eating practices.
Time frame: Immediately after the 6-week intervention (T1) and 3 months after the intervention (T2)
Sustainable Eating Action Strategy
Sustainable eating action strategy will be assessed using four items adapted from the Sustainable Food Literacy Scale. Items are rated on a 7-point scale from 1 (strongly disagree) to 7 (strongly agree). A mean score ranging from 1 to 7 will be calculated, with higher scores indicating greater use of sustainable eating strategies.
Time frame: Immediately after the 6-week intervention (T1) and 3 months after the intervention (T2)
Healthy Eating Behaviors
Healthy eating behaviors will be assessed using a 13-item instrument developed for Taiwanese university students. Items are rated on a 5-point scale from 1 (never) to 5 (always). A mean score ranging from 1 to 5 will be calculated, with higher scores indicating healthier eating behaviors.
Time frame: Immediately after the 6-week intervention (T1) and 3 months after the intervention (T2)
