The aim of this study was to determine the e?ectiveness of conventional nutrition education on knowledge and self-e?cacy of COVID-19 prevention e?orts. Study subjects of this study were 23 adults aged 19-65 years and taken by total sampling method. Nutritional knowledge data were collected using a questionnaire containing ten questions, while self-e?cacy was assessed by creating a structured questionnaire on a scale of 0-100. Conventional education was given in the form of lectures related to the role of balanced nutrition, hoaxes related to food to prevent or treat COVID-19, and other COVID-19 prevention e?orts for 90 minutes. Before and after education data were analyzed using paired t-test with SPSS version 23. This study results showed that nutrition education significantly improves nutritional knowledge (mean score before and after = 69.6 + 10.2 and 85.7 + 10.4; p < 0.001), self-e?cacy to apply a balanced nutrition pattern (mean scores before and after = 68.2 + 13.0 and 75.5 + 17.5; p = 0.014), and the self-e?cacy of implementing the health protocol (mean score before and after = 82.3 + 7.8 and 87.0 + 6.8; p = 0.002). This research can be used as a benchmark for the importance of expanding the coverage of conventional nutrition education to the wider community.
