Nutrition Knowledge and Diet in Female College Students in Turkey: Youth Education in Nutrition Initiative/Nutrition Education Works (YENI/NEW)—A Cross-Sectional Pilot Study

Abstract

Healthy dietary patterns can play a major role in preventing chronic diseases. Improving nutrition-related knowledge in young individuals is considered a promising approach to adopting healthy dietary behaviors, thus improving outcomes later in life. However, healthy eating habits in college students may prove challenging to acquire and maintain. This cross-sectional pilot study aimed to investigate the relationship between nutrition knowledge and its effect on dietary factors, body weight, and body composition in female college students in Turkey. Second- and third-year female college nutrition students (NS), (n = 85) and corresponding non-nutrition/non-health sciences students (NNS) (n = 80), aged 20–22 years old, were evaluated using a validated nutrition knowledge questionnaire, 24 h recalls, anthropometry, and body composition analysis using bioelectrical impedance during the 2015–2016 academic year. The findings revealed that nutrition knowledge was positively associated with increased intake of water, fruits and vegetables, grains, and fiber, whereas total carbohydrate intake exhibited an inverse relationship with nutrition knowledge. Moreover, protein and lipid intake, while not significant, appeared to show higher and lower values, respectively, for the NS participants compared to NNS, revealing a healthier trend for more nutrition-knowledgeable students, which was similar to the finding of a marginally better body composition profile in nutrition-knowledgeable students. As young adulthood is critical for the development of dietary habits, demonstrating the effectiveness of nutrition education is important as a potential tool for public health in terms of improving the risk of chronic diseases.
