Abstract: Nutrition and disease course is a core interdisciplinary course for doctoral students in medicine, nutrition, and public health; it connects basic nutritional science, clinical disease prevention and treatment, and public health practice, and its teaching quality directly affects the cultivation of high-level nutritional talents'capabilities in scientific research innovation and theoretical application. To address issues in its teaching, such as the disconnection between theory and application, and the separation of scientific research from teaching, a teaching reform plan is proposed based on the Outcome-Based Education (OBE) concept, focusing on three aspects: reconstructing the theoretical teaching system, integrating interdisciplinary teaching, and developing digital teaching resources. This plan has been applied to the teaching of doctoral students in the field of public health and preventive medicine, and its effectiveness has been verified through a two-dimensional knowledge-ability evaluation. Results show that doctoral students have significantly improved their mastery of cutting-edge knowledge in this field and strengthened the connection between their research topic selection and theoretical application. This plan can thus provide a reference for the theoretical teaching of high-level interdisciplinary medical courses under the background of the new medical education initiative.
