Introduction: The Sustainable Development Goals promote quality education and healthy eating, and nursing is a fundamental profession for their fulfilment due to its educational role. Project-based learning is an innovative methodology for acquiring competencies; however, its impact on nursing students needs further study.
Aim: This study evaluates whether project-based learning effectively modifies nursing students' nutritional behaviours to align with the Sustainable Development Goals.
Materials and methods: A longitudinal quasi-experimental study with a pretest-posttest design was conducted. 50 first-year nursing students participated, completing an online questionnaire at four stages: program start, pre-implementation, six weeks post-implementation, and one year later. The questionnaire assessed eating habits, food consumption frequency, choices, beliefs and preferences.
Results: Project-based learning was associated with small short-term improvements in some eating habits and indicators of long-term adherence to the Mediterranean Diet, although effects were not consistent across time points.
Conclusions: Project-based learning is an effective tool in nursing education, enhancing nutrition knowledge application in real-life situations, leading to sustainable improvements in eating habits and supporting the simulation of quality education and health promotion.
