| Outline of Final Research Achievements |
We analyzed the food substances that inhibit intestinal monosaccharide absorption to prevent the diseases caused by excessive carbohydrates. We searched for phytochemicals that inhibit glucose transporter SGLT1, responsible for glucose absorption, and also GLUT5, responsible for fructose absorption. We found that tangeretin contained in citrus fruits and epicatechin gallate contained in green tea inhibited SGLT1 and GLUT5 activity. Oral glucose tolerance test using mice showed that tangeretin significantly suppressed the increase in mouse blood glucose level.
