Summary

Anthocyanins are a subclass of (poly)phenols very abundant in berries and red grapes. Increasing evidence from human epidemiological and dietary intervention studies suggests that anthocyanins may have cardiovascular health benefits. The present study aimes to investigate whether pure anthocyanin consumption improves endothelial function in healthy individuals and if these effects are dose-dependent.

Detailed description

Anthocyanins are a subclass of (poly)phenols very abundant in berries and red grapes. Increasing evidence from human epidemiological and dietary intervention studies suggests that anthocyanins may have cardiovascular health benefits. A double blind randomized controlled crossover, dose-response study will be conducted in 10 young healthy men. On 6 different days, subjects will consume capsules containing 0, 80, 160, 240, 320 and 480 mg of purified anthocyanins with a one-week wash-out period. Flow-mediated dilation (FMD) and blood pressure will be measured at baseline and at 2 and 6 h after consumption. Blood samples will also be taken and quantification of plasma anthocyanin metabolites using UPLC-Q-TOF-MS will be performed. The aim is to investigate whether purified anthocyanins are able to increase FMD at 2h and 6h post consumption and whether these effects correlate with anthocyanin- derived phenolic acids quantified in the plasma.
