We examined the skin condition effect of pre-germinated brown rice on healthy female university students. They ingested 320g of cooked pre-germinated brown rice as the staple food daily for 8 weeks. Consequently, in spite of being examined in the autumn to winter period, a significant change was not seen in the moisture content of the horny layer, the “rough skin” condition has been improved. It was proved that the tendency on the skin color showed a rise of brightness and decrease of redness by apparatus tools of analysis and the questionnaire. The moisture content of the horny layer, improvement in softness, and the rise in the amount of collagen in the skin was noted on the arm and cheek. Therefore 70% persons with the condition, “the inelastic skin”, before the examination have shown improvement by questionnaire. Moreover, as for the constipation condition, 95% have been improved by the increase in the amount of dietary fiber intake of the pre-germinated brown rice origin, along with improvement in the environment of the intestines. As a result of this study, the validity of the benefits of pre-germinated brown rice was demonstrated with the improvement of skin condition, such as the moisture content of horny layer, skin color and softness was accomplished by ingestion.
