Outline of Final Research Achievements

A dietary combination contributes to the development of metabolic disorders. (1) We observed the time course of gene expression changes in peripheral white blood cells to elucidate the metabolic changes in the postprandial state. Several genes involved in glycolysis and fatty acid β-oxidation were markedly changed after the intake of glucose, white rice and rolled barley. Low glycemic index (GI) diet induced improvement of insulin resistance by accelerated beta-oxidation through increased expression of PPAR-alpha and gamma gene. (2)The effect of dietary energy density (ED) on appetite sensation was also examined. High vegetable content in the low-ED diet model provided sufficient fullness and satisfaction and increased rice content is more effective for satiety than increased meat content for adults aged around 40 years. Low rice intake in a low ED diet also caused a relative stimulation of sweetness desire in women.　Thus, GI and ED in diet are useful indexes of health and disease.
