Purpose: In this study, we compared the subjective symptoms and changes in skin condition of university students that consumed sub-aleurone layer residual rinse-free rice (SARFR; Kinmemai rice) for one month, with polished rice free intake group.
Method: The 59 subjects analyzed consisted of 37 in the SARFR group (24 males, 13 females 21.0 ± 1.5 years), and 22 in the control group (13 males, 9 females, 22.0 ± 1.2 years). In the SARFR group, 150 g or more of the test meal was ingested once a day for one month. In the control group, normal ingestion of polished rice was freely decided by participants. Before and after the test, the questionnaire, skin function by Clreo-Pro (Fujitex), and skin AGEs fluorescence by AGEs sensor (Sharp) were evaluated.
Results: SARFR intake compliance was 84%, and no adverse events due to dyspepsia were observed. Skin age was significantly improved in the SARFR group compared to the control. This effect was remarkable for males and home students, and was not observed in boarding house students. There was no significant difference in skin AGEs fluorescence.
Conclusion: It was suggested that SARFR contributes to health promotion, including skin condition, by reducing the indigestibility of brown rice and ensuring nutrition, which facilitates continuous intake.
