Outline of Final Research Achievements

We fixed flavonoid-enriched test meals considering energy and PFC ratio, and we investigated disposition of dietary-derived flavonoids after consuming test meals in seven healthy subjects. Also, we verify the effects of short-term continual intakes for the flavonoid-enriched diet on inflammatory markers in six obese subjects (BMI≧25) through comparison of a case for flavonoid-poor meals.
It was shown that the plasma flavonoid levels rose significantly and maintained at the high level for nine hours after consuming test meals. Moreover, it was confirmed that gene expression of inflammatory cytokines such as TNF-α in blood cells decreased after continually consuming the flavonoid-enriched meals in extremely obese subjects (BMI≧30).
