The goal of this clinical trial is aimed to examine the effect of food safety and security and waste reduction education on the knowledge, attitudes, behavior, and practices of undergraduates.

The main questions it aims to answer are:

Will the food consumption record of the experimental group be lower than the control group after the training? Will the experimental group's post-training food insecurity scale scores be higher than the control group? Will the experimental group's waste level be lower after the training than the control group? Will the experimental group's food safety knowledge test scores be higher than the control group?

Initiatives aimed at ensuring access to safe, nutritious, and adequate food and the reduction of food waste are critical for social well-being and sustainable development. This project is aimed to examine the effect of food safety and security and waste reduction education on the knowledge, attitudes, behavior, and practices of undergraduates. The research was designed as a randomized controlled trial in which the pre-test-post-test method will be applied. The participants of the study will consist of 110 (n intervention = 55, n control = 55) students studying at Selcuk University with the G*Power 3.1.9.7 power analysis program. A grading randomization method will be used accordingly to the faculties. Through the research, participants will be provided with training consisting of 14 sessions on food safety, food security, and the reduction of food waste. Research data will be collected with; general information part, 24-hour recalled food consumption record, Food Insecurity Experience Scale, food consumption frequency form, management of food consumption-related behaviors, and food waste questionnaire form, and Food Safety, Attitudes, and Behaviors Scale. In addition, body weight (kg), height (m), waist (cm), hip (cm), and neck (cm) measurements will be taken from the participants in the study. The research findings will be analyzed by t-test in the groups dependent on the changes within the intervention and control groups; t-test in the independent groups. Furthermore, the Cohen d power level will be calculated, and the group time interaction between the groups will be evaluated by two-way analysis of variance and partial ETA recalculation in repetitive measurements. In case of data loss, a Little's Mcar test will be performed based upon the result of which the data will be analyzed and evaluated via the Intention-to-treat protocol by completing the data.
