Objective: The purpose of this study was to investigate effects of Japanese dietary pattern on defecation in young Japanese women. Methods:The subjects were nineteen female university students (21-24 years old), who gave informed consent to their participation in the study. The total study period was twelve weeks including a four-week observation period,and an eight-week intervention (40 lunch meals of Japanese dietary pattern,5 meals per week)period. The subjects recorded daily defecation,food intake,and special circumstances that may have influenced defecation. Food frequency questionnaires were administered during the observation and intervention periods, respectively. Results: The defecation frequency(from 22 to 31)and quantity(from 22 to 36)in the intervention period from five to eight weeks were significantly increased as compared with those in the observation period. In the food frequency questionnaires, intake of grain,vegetables and seaweeds in the intervention period were significantly increased as compared with those in the observation period. These increased intakes could affect defecation. Conclusion: These results indicate that the Japanese dietary pattern has a beneficial effect on defecation in young Japanese women.
