This study used a questionnaire and photographs of dishes to analyze daily meals of students, with a focus on staple food preference. The study compares the characteristics of actual meals of two groups: a “rice group” who regularly eat rice for breakfast, and a “bread group” who regularly eat bread for breakfast. In addition, the impact of staple food consumption for breakfast on dietary patterns of breakfast and dinner was analyzed. Using a brief-type self-administered diet history questionnaire (BDHQ), we also examined whether there was any difference between the rice group and the bead group in terms of nutrients and food products consumed.
In terms of feeling satisfied after a main dish and side dish for breakfast, the rice group felt more satisfied. Regarding the impact of staple food consumption for breakfast on dietary patterns of dinner, the rice group consumed more fruits. From the results of a brief-type self-administered diet history questionnaire (BDHQ) on those who answered “almost always eat rice for breakfast” and “almost always eat bread for breakfast”, there was no significant difference in nutrients. With respect to types of food products, a significant difference was found in rice, bread, and seasonal citrus fruits. It was found that seasonal citrus fruits were consumed more by the “almost always eat rice” group.
These results suggest that those who have a habit of eating rice for breakfast may adopt a more balanced diet
