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.

The Relationship Between Ultra-Processed Food Consumption and Oral Health

The goal of this observational study is to examine the potential relationship between ultra-processed food consumption and the presence of dental caries and periodontal disease, and to evaluate the role of the Ultra-Processed Food Index (UPFI) in this association. The main question it aims to answer is: Does increased consumption of ultra-processed foods raise the risk or severity of dental caries and periodontal disease in individuals? Participants will include individuals within a specified age range who voluntarily agree to participate in the study. Oral health status will be assessed through standard clinical parameters, including the presence of caries, plaque index, probing pocket depth, clinical attachment loss, and bleeding on probing. Dietary habits will be evaluated using a validated food frequency questionnaire, and individual UPFI scores will be calculated. The study will aim to observe and analyze the effects of ultra-processed food consumption on oral health outcomes.
