Here’s something for teetotalers out there: a new study indicates that not only does Concord grape juice stimulated an arterial relaxation effect in a similar fashion to red wine, in fact it even induced a prolonged relaxation effect that has not yet been reported with red wine.
Dr. ValĂ©rie Schini-Kerth and a team of researchers of the UniversitĂ© Louis Pasteur de Strasbourg, France, found that Concord grape juice stimulated the production of nitric oxide in endothelial cells, providing a vasorelaxation effect. It is known that nitric oxide is important in the bodyâ€™s natural system for maintaining healthy, flexible blood vessels and helps support healthy blood pressure.
Researchers further discovered that Concord grape juice produced this relaxation effect by stimulating the same chemical reactions in the arteries that are activated by red wine. The beneficial effect provided by Concord grape juice lasted up to six hours, whereas this extended effect has not been reported with red wine. This research suggests that the benefits of drinking Concord purple grape juice may last long after finishing the juice.
