Abstract
Purpose: In this study, we compared the subjective symptoms and changes in skin condition of university students and staffs with brown rice from which the bran layer had been removed (dewaxed brown rice: DBR) for one month, in comparison with the polished rice free intake group.
Methods: The 65 subjects in the analysis group consisted of 43 in the DBR group (25 males and 18 females 23.8 ± 8.8 years) and 22 in the control group (13 males and 9 females 22.0 ± 1.2 years). In the DBR group, a test meal of 150 g or more was ingested once a day for one month, and in the control group, polished rice was usually taken freely. Before and after the test, the questionnaire, skin condition (Clreo-Pro), and skin AGE fluorescence (by AGEs sensor) were evaluated.
Results: DBR intake compliance was at 87.5%, and no adverse events due to dyspepsia were observed. Skin age, an index of skin condition, was significantly improved in the DBR group compared to the control. There was no significant difference in skin AGE fluorescence. Gender analysis showed that wrinkles and porphyrin levels were significantly improved in the DBR group in women.
Conclusion: It was suggested that DBR could contribute to health promotion including skin condition by reducing the indigestibility of brown rice and ensuring nutritional value, which facilitates continuous intake.
