Scavenging of Reactive Carbonyl Species by Dietary Flavonoids in Humans

Status Completed

Clinical Trial Summary

This is an interventional study to investigate the formation and pharmacokinetics of reactive carbonyl species adducts of dietary polyphenols (soymilk, green tea, and blueberry) in humans after a single dose of dietary flavonoids.

Clinical Trial Description

A crossover design was used. Sixteen healthy volunteers (16 for each study, in total 48) were recruited and asked to avoid the consumption of any soymilk, green tea, and blueberry products starting 1 week before intervention and continuing throughout the entire study for a total of 3 weeks. On week 2, each of the eight participants received 460 ml of soymilk, green tea, and blueberry in a single dose, and afterward, urine and blood samples at different time points over 24 h and fecal samples at different time points over 48 h were collected. Meanwhile, the other eight participants received breakfast (without any soymilk, green tea, and blueberry) at different time points over 48 h were collected. On the contrary, on week 3, eight participants who received regular milk or water on week 2 received breakfast only, and eight participants who were used as a control on week 2 received soymilk, green tea, and blueberry. And urine and blood samples at different time points over 24 h, and fecal samples at different time points over 48 h for both groups were collected. Samples will be analyzed by LC-MS/MS. The Pharmacokinetics of conjugates will be investigated. ;
