| Outline of Final Research Achievements |
Bacterial species in human gut microbiota, which are analyzed by a next-generation genome sequencer, reviled to be available to apply in epidemiologic studies. To make use of cancer prevention method on the prostate and breast, this study showed each proportion of carriers with bacteria species, but not genus, on the metabolism of soy isoflavone daizein to equol, and their seasonal variations in Japanese men and women.
This study also demonstrated that there were both seasonal variations and chrono-nutritional effects on negative relationships between green tea intake and the two types of obesity on body weight and visceral fat, especially in Shizuoka men and women with the highest levels of healthy aging and lower rates of obesity. For preventing obesity and longevity of health expectancy, the findings may be thought to be available to advice when and how much to take green tea.
