Effects of phenolics on vascular endothelial function
Abstract
Purpose of review: There continues to be considerable interest in the concept that antioxidant therapy may reduce cardiovascular risk. Phenols have antioxidant properties and may be important micronutrients. Epidemiological studies have demonstrated a strong link between phenolic intake and reduced cardiovascular risk, but the mechanism of benefit has not been determined.
Recent findings: Recent evidence has emerged that a number of phenolic compounds, particularly flavonoids, reverse vascular endothelial dysfunction. The normal endothelium plays a critical role in regulating vascular function, and endothelial dysfunction is associated with increased cardiovascular risk. The present article reviews the links between phenolic intake, endothelial function and cardiovascular risk.
Summary: Endothelium-derived nitric oxide bioactivity appears to be increased by supplementation with a number of phenols, and this may explain some of the favourable effects of high phenolic intake seen in epidemiological studies.
