Brief Summary
In this proposed human trial, the investigators aim to establish whether 4 weeks of daily consumption of beta-glucan matched meals providing either a high dose or a moderate dose of oat avenanthramides and phenolic acids leads to dose-dependent chronic improvements in markers of CVD risk and gut health relative to an energy matched control intervention in healthy adults with above average blood pressure.
