Effect of a Nutrition Education Intervention on Ultra-Processed Food Awareness and Consumption Among University Students

Ultra-processed foods are industrially formulated products that often contain high amounts of salt, sugar, and saturated fat, as well as additives. Higher consumption of these foods has been associated with several chronic diseases. Medical students may be at increased risk of unhealthy dietary behaviors and food insecurity. This study aims to evaluate the effects of a low-cost nutrition education program on medical students' knowledge and attitudes about ultra-processed foods, ultra-processed food consumption, nutrition label literacy, and nutrition self-efficacy. A total of 74 sixth-year medical students at Eskisehir Osmangazi University Faculty of Medicine will be assigned by clusters to either an intervention group or a control group. The intervention group will participate in an educational program about ultra-processed foods, food labels, and healthier food choices. The control group will not receive this educational program during the study period. Data will be collected at baseline, immediately after the intervention, and at the one-month follow-up. The study will assess food security, knowledge and attitudes regarding ultra-processed foods, ultra-processed food consumption, nutrition label literacy, nutrition self-efficacy, and dietary intake based on three-day food records.
