Polyphenols Protect Against Blood Vessel Deterioration

The endothelium is the inner lining of your blood vessels. Its functions include enabling coagulation, platelet adhesion and immune reaction, and endothelial dysfunction is associated with reduced anticoagulant properties and other problems. The gradual decrease in endothelial function over time is a key factor in diseases associated with aging.

A new study examined whether intake of red wine polyphenols, a rich source of natural antioxidants, could prevents age-related impairment of vascular function. It found that intake of these polyphenols provided a protective effect against both aging-induced endothelial dysfunction and decline in physical performance.

According to Eurekalert:

"These effects likely involve the ability of [red wine polyphenols] to normalize oxidative stress and the expression of proteins involved in the formation of NO and the angiotensin II pathway."
