<;P>;PROBLEM TO BE SOLVED: To clarify a new action mechanism of a sterol glycoside contained in germinated unpolished rice and, particularly, to provide a safe IGF-1 secretion promoter exhibiting effects for ameliorating diabetic pathology and protecting a pancreatic cell. <;P>;SOLUTION: The IGF-1 secretion promoter comprises a sterol glycoside derived from germinated unpolished rice as an effective ingredient. In the IGF-1 secretion promoter, the sterol glycoside derived from germinated unpolished rice is a sterol derived from bran of germinated unpolished rice. <;P>;COPYRIGHT: (C)2011,JPO&INPIT
