Good nutrition is essential for all treatments and health. Therefore, it is very important for pharmacists to have good nutritional knowledge in carrying out pharmaceutical care, especially for elderly patients. However, pharmaceutical students receive insufficient nutritional education. In the present study, we evaluated the educational effects by means of intervention. Thirty-eight pharmaceutical students attending the hospital practical training participated in this study during the period of 2015. The test was carried out twice; at the beginning of clinical training and after attending the nutrition support team conference and rounds. The test results showed that the total scores significantly increased from 12.2 ± 4.7 to 22.6 ± 5.1 after our intervention (P < 0.01). The questionnaires revealed the current students' situation of nutritional education in the college of pharmacy and the fundamental aim for them. Most answered that they wanted to continue to learn about nutrition. These results suggest that our intervention in hospital practical training was useful not only in improving their knowledge but also in enhancing their interest in nutrition.
